Fix multiple issues with def --wrapped help example (#13123)
# Description

I've noticed this several times but kept forgetting to fix it:

The example given for `help def` for the `--wrapped` flag is:

```nu
Define a custom wrapper for an external command
> def --wrapped my-echo [...rest] { echo $rest }; my-echo spam
  ╭───┬──────╮
  │ 0 │ spam │
  ╰───┴──────╯
```

That's ... odd, since (a) it specifically says *"for an external"*
command, and yet uses (and shows the output from) the builtin `echo`.
Also, (b) I believe `--wrapped` is *only* applicable to external
commands. Finally, (c) the `my-echo spam` doesn't even demonstrate a
wrapped argument.

Unless I'm truly missing something, the example just makes no sense.

This updates the example to really demonstrate `def --wrapped` with the
*external* version of `^echo`. It uses the `-e` command to interpret the
escape-tab character in the string.

```nu
> def --wrapped my-echo [...rest] { ^echo ...$rest }; my-echo -e 'spam\tspam'
spam  spam
```

path type error and not found changes (#13007)
# Description
Instead of an empty string, this PR changes `path type` to return null
if the path does not exist. If some other IO error is encountered, then
that error is bubbled up instead of treating it as a "not found" case.

# User-Facing Changes
- `path type` will now return null instead of an empty string, which is
technically a breaking change. In most cases though, I think this
shouldn't affect the behavior of scripts too much.
- `path type` can now error instead of returning an empty string if some
other IO error besides a "not found" error occurs.

Since this PR introduces breaking changes, it should be merged after the
0.94.1 patch.

After parsing menu code, the changes weren't merged into the engine
state, which didn't produce any errors (somehow?) until the recent span
ID refactors. With this PR, menus get a new cloned engine state with the
parsed changes correctly merged in.

Deprecate --numbered from for (#13112)
# Description

#7777 removed the `--numbered` flag from `each`, `par-each`, `reduce`,
and `each while`. It was suggested at the time that it should be removed
from `for` as well, but for several reasons it wasn't.

This PR deprecates `--numbered` in anticipation of removing it in 0.96.

Note: Please review carefully, as this is my first "real" Rust/Nushell
code. I was hoping that some prior commit would be useful as a template,
but since this was an argument on a parser keyword, I didn't find too
much useful. So I had to actually find the relevant helpers in the code
and `nu_protocol` doc and learn how to use them - oh darn ;-) But please
make sure I did it correctly.

# User-Facing Changes

* Use of `--numbered` will result in a deprecation warning.
* Changed help example to demonstrate the new syntax.
* Help shows deprecation notice on the flag

Part of https://github.com/nushell/nushell/issues/12963, step 2.

This PR refactors changes the use of `expression.span` to
`expression.span_id` via a new helper `Expression::span()`. A new
`GetSpan` is added to abstract getting the span from both `EngineState`
and `StateWorkingSet`.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

`format pattern` loses the ability to use variables in the pattern,
e.g., `... | format pattern 'value of {$it.name} is {$it.value}'`. This
is because the command did a custom parse-eval cycle, creating spans
that are not merged into the main engine state. We could clone the
engine state, add Clone trait to StateDelta and merge the cloned delta
to the cloned state, but IMO there is not much value from having this
ability, since we have string interpolation nowadays: `... | $"value of
($in.name) is ($in.value)"`.

Fix the colors when completing using a relative path (#12898)
# Description
Fixes a bug where the autocompletion menu has the wrong colors due to
'std::fs::symlink_metadata' not being able to handle relative paths.
Attached below are screenshots before and after applying the commit, in
which the colors are wrong when autocompleting on a path prefixed by a
tilde, whereas the same directory is highlighted correctly when prefixed
by a dot.

Use native toml datetime type in to toml (#13018)
# Description

Makes `to toml` use the `toml::value::Datetime` type, so that `to toml`
serializes dates properly.


# User-Facing Changes

`to toml` will now encode dates differently, in a native format instead
of a string. This could, in theory, break some workflows:

```Nushell

Allow stor insert and stor update to accept pipeline input (#12882)
- this PR should close #11433 

# Description
This PR implements pipeline input support for the stor insert and stor
update commands,
enabling users to directly pass data to these commands without relying
solely on flag parameters.

Previously, it was only possible to specify the record data using flag
parameters,
which could be less intuitive and become cumbersome:

```bash
stor insert --table-name nudb --data-record {bool1: true, int1: 5, float1: 1.1, str1: fdncred, datetime1: 2023-04-17}
stor update --table-name nudb --update-record {str1: nushell datetime1: 2020-04-17}
```

Now it is also possible to pass a record through pipeline input:

```bash
{bool1: true, int1: 5, float1: 1.1, str1: fdncred, datetime1: 2023-04-17} | stor insert --table-name nudb
{str1: nushell datetime1: 2020-04-17} | stor update --table-name nudb"
```

Changes made on code:

- Modified stor insert and stor update to accept a record from the
pipeline.
- Added logic to handle data from the pipeline record.
- Implemented an error case to prevent simultaneous data input from both
pipeline and flag.

# User-facing changes

Returns an error when both ways of inserting data are used.

The examples for both commands were updated and in each command, when
the -d or -u fags are being used at the same time as input is being
passed through the pipeline, it returns an error:


![image](https://github.com/nushell/nushell/assets/120738170/c5b15c1b-716a-4df4-95e8-3bca8f7ae224)

Also returns an error when both of them are missing:

Overhaul explore config (#13075)
Configuration in `explore` has always been confusing to me. This PR
overhauls (and simplifies, I think) how configuration is done.

# Details

1. Configuration is now strongly typed. In `Explore::run()` we create an
`ExploreConfig` struct from the more general Nu configuration and
arguments to `explore`, then pass that struct to other parts of
`explore` that need configuration. IMO this is a lot easier to reason
about and trace than the previous approach of creating a
`HashMap<String, Value>` and then using that to make various structs
elsewhere.
2. We now inherit more configuration from the config used for regular Nu
tables
1. Border/line styling now uses the `separator` style used for regular
Nu tables, the special `explore.split_line` config point has been
retired.
2. Cell padding in tables is now controlled by `table.padding` instead
of the undocumented `column_padding_left`/`column_padding_right` config
3. The (optional, previously not enabled by default) `selected_row` and
`selected_column` configuration has been removed. We now only highlight
the selected cell. I could re-add this if people really like the feature
but I'm guessing nobody uses it.

The interface still looks the same with a default/empty config.nu:

Fix explore panic on empty lists (#13074)
This fixes up a panic I accidentally introduced when refactoring the
cursor code in `explore`: https://github.com/nushell/nushell/pull/12979

Under certain circumstances (running `:nu []`, opening `:try` with the
hidden `try.reactive` setting enabled), `explore` would panic when
handling an empty list. To fix this for now I've removed the validation
I added to the Cursor constructor in that PR.

cd/def --env examples (#13068)
# Description

Per a Discord question
(https://discord.com/channels/601130461678272522/1244293194603167845/1247794228696711198),
this adds examples to the `help` for both:

* `cd`
* `def`

to demonstrate that `def --env` is required when changing directories in
a custom command.

Since the existing examples for `def` were a bit more complex (and had
output) but the `cd` ones were more simplified, I did use slightly
different examples in each. Either or both could be tweaked if desired.

reduce log tracing in nu-cli (#13067)
This one trace message creates thousands of lines of trace messages that
is probably
better suited to using on an *as needed* basis rather than everyone
having to wade
through it...

For now, I just commented it out but eventually this line of code should
be removed
and used simply for the time when someone needs to see it...

Refactor explore cursor code (#12979)
`explore` has 3 cursor-related structs that are extensively used to
track the currently shown "window" of the data being shown. I was
finding the cursor code quite difficult to follow, so this PR:
- rewrites the base `Cursor` struct from scratch, with some tests
- makes big changes to `WindowCursor`
- renames `XYCursor` to `WindowCursor2D`
- makes some of the cursor functions fallible as a start towards better
error handling
- changes lots of function names to things that I find more intuitive
- adds comments, including ASCII diagrams to explain how the cursors
work

More work could be done (I'd like to review/change more function names
in `WindowCursor` and `WindowCursor2D` and add more tests), but this is
the limit of what I can get done in a weekend. I think this part of the
code is in a better place now.

# Testing performed

I did a lot of manual testing in the record view and binary viewer,
moving around with arrow keys / page up+down / home+end.

This can definitely wait until after the release freeze, this area has
very few automated tests and it'd be good to let the changes bake a bit.

Span ID Refactor - Step 1 (#12960)
# Description
First part of SpanID refactoring series. This PR adds a `SpanId` type
and a corresponding `span_id` field to `Expression`. Parser creating
expressions will now add them to an array in `StateWorkingSet`,
generates a corresponding ID and saves the ID to the Expression. The IDs
are not used anywhere yet.

For the rough overall plan, see
https://github.com/nushell/nushell/issues/12963.

# User-Facing Changes
Hopefully none. This is only a refactor of Nushell's internals that
shouldn't have visible side effects.

msgpackz: increase default compression level (#13035)
# Description
Increase default compression level for brotli on msgpackz to 3. This has
the best compression time generally. Level 0 and 1 give weird results
and sometimes cause extremely inflated outputs rather than being
compressed. So far this hasn't really been a problem for the plugin
registry file, but has been for other data.

The `$example` is the web-app example from https://json.org/example.html

Benchmarked with:

```nushell
seq 0 11 | each { |level|
  let compressed = ($example | to msgpackz --quality $level)
  let time = (timeit { $example | to msgpackz --quality $level })
  {
    level: $level
    time: $time
    length: ($compressed | bytes length)
    ratio: (($uncompressed_length | into float) / ($compressed | bytes length))
  }
}
```

Try to preserve the ordering of elements in from toml (#13045)
# Description

Enable the `preserve_order` feature of the `toml` crate to preserve the
ordering of elements when converting from/to toml.

Additionally, use `to_string_pretty()` instead of `to_string()` in `to
toml`. This displays arrays on multiple lines instead of one big single
line. I'm not sure if this one is a good idea or not... Happy to remove
this from this PR if it's not.

# User-Facing Changes
The order of elements will be different when using `from toml`. The
formatting of arrays will also be different when using `to toml`. For
example:

- before
```
❯ "foo=1\nbar=2\ndoo=3" | from toml
╭─────┬───╮
│ bar │ 2 │
│ doo │ 3 │
│ foo │ 1 │
╰─────┴───╯
❯ {a: [a b c d]} | to toml
a = ["a", "b", "c", "d"]
```
- after
```
❯ "foo=1\nbar=2\ndoo=3" | from toml
╭─────┬───╮
│ foo │ 1 │
│ bar │ 2 │
│ doo │ 3 │
╰─────┴───╯
❯ {a: [a b c d]} | to toml
a = [
    "a",
    "b",
    "c",
    "d",
]

Make LS_COLORS functionality faster in explore, especially on Windows (#12984)
Closes #12980. More context there, but basically `explore` was getting

Fix run_external::expand_glob() to return paths that are PWD-relative but reflect the original intent (#13028)
# Description

Fix #13021

This changes the `expand_glob()` function to use
`nu_engine::glob_from()` so that absolute paths are actually preserved,
rather than being made relative to the provided parent. This preserves
the intent of whoever wrote the original path/glob, and also makes it so
that tilde always produces absolute paths.

I also made `expand_glob()` handle Ctrl-C so that it can be interrupted.

Disallow more characters in arguments for internal cmd commands (#13009)
# Description
Makes `run-external` error if arguments to `cmd.exe` internal commands
contain newlines or a percent sign. This is because the percent sign can
expand environment variables, potentially? allowing command injection.
Newlines I think will truncate the rest of the arguments and should
probably be disallowed to be safe.

# After Submitting
- If the user calls `cmd.exe` directly, then this bypasses our
handling/checking for internal `cmd` commands. Instead, we use the
handling from the Rust std lib which, in this case, does not do special
handling and is potentially unsafe. Then again, it could be the user's
specific intention to run `cmd` with whatever trusted input. The problem
is that since we use the std lib handling, it assumes the exe uses the C
runtime escaping rules and will perform some unwanted escaping. E.g., it
will add backslashes to the quotes in `cmd echo /c '""'`.
- If `cmd` is called indirectly via a `.bat` or `.cmd` file, then we use
the Rust std lib which has separate handling for bat files that should
be safe, but will reject some inputs.
- ~~I'm not sure how we handle `PATHEXT`, that can also cause a file
without an extension to be run as a bat file. If so, I don't know where
the handling, if any, is done for that.~~ It looks like we use the
`which` crate to do the lookup using `PATHEXT`. Then, we pass the exe
path from that to the Rust std lib `Command`, which should be safe
(except for the first `cmd.exe` note).

So, in the future we need to unify and/or fix these different
implementations, including our own special handling for internal `cmd`
commands that this PR tries to fix.

Restore tilde expansion on external command names (#13001)
# Description

Fix a regression introduced by #12921, where tilde expansion was no
longer done on the external command name, breaking things like

```nushell
> ~/.cargo/bin/exa
```

This properly handles quoted strings, so they don't expand:

```nushell
> ^"~/.cargo/bin/exa"
Error: nu:🐚:external_command

  × External command failed
   ╭─[entry #1:1:2]
 1 │ ^"~/.cargo/bin/exa"
   ·  ─────────┬────────
   ·           ╰── Command `~/.cargo/bin/exa` not found
   ╰────
  help: `~/.cargo/bin/exa` is neither a Nushell built-in or a known external command

```

This required a change to the parser, so the command name is also parsed
in the same way the arguments are - i.e. the quotes on the outside
remain in the expression. Hopefully that doesn't break anything else. 🤞

Fixes #13000. Should include in patch release 0.94.1

cc @YizhePKU

# User-Facing Changes
- Tilde expansion now works again for external commands
- The `command` of `run-external` will now have its quotes removed like
the other arguments if it is a literal string
- The parser is changed to include quotes in the command expression of
`ExternalCall` if they were present

# Tests + Formatting
I would like to add a regression test for this, but it's complicated
because we need a well-known binary within the home directory, which
just isn't a thing. We could drop one there, but that's kind of a bad
behavior for a test to do. I also considered changing the home directory
for the test, but that's so platform-specific - potentially could get it
working on specific platforms though. Changing `HOME` env on Linux
definitely works as far as tilde expansion works.

make polars plugin use mimalloc (#12967)
# Description
@maxim-uvarov did a ton of research and work with the dply-rs author and
ritchie from polars and found out that the allocator matters on macos
and it seems to be what was messing up the performance of polars plugin.
ritchie suggested to use jemalloc but i switched it to mimalloc to match
nushell and it seems to run better.

## Before (default allocator)
note - using 1..10 vs 1..100 since it takes so long. also notice how
high the `max` timings are compared to mimalloc below.
```nushell

Do not propagate glob creation error for external args (#12955)
# Description
Instead of returning an error, this PR changes `expand_glob` in
`run_external.rs` to return the original string arg if glob creation
failed. This makes it so that, e.g.,
```nushell
^echo `[`
^echo `***`
```
no longer fail with a shell error. (This follows from #12921.)

Allow byte streams with unknown type to be compatiable with binary (#12959)
# Description
Currently, this pipeline doesn't work `open --raw file | take 100`,
since the type of the byte stream is `Unknown`, but `take` expects
`Binary` streams. This PR changes commands that expect
`ByteStreamType::Binary` to also work with `ByteStreamType::Unknown`.
This was done by adding two new methods to `ByteStreamType`:
`is_binary_coercible` and `is_string_coercible`. These return true if
the type is `Unknown` or matches the type in the method name.

Make from json --objects streaming (#12949)
# Description

Makes the `from json --objects` command produce a stream, and read
lazily from an input stream to produce its output.

Also added a helper, `PipelineData::get_type()`, to make it easier to
construct a wrong type error message when matching on `PipelineData`. I
expect checking `PipelineData` for either a string value or an `Unknown`
or `String` typed `ByteStream` will be very, very common. I would have
liked to have a helper that just returns a readable stream from either,
but that would either be a bespoke enum or a `Box<dyn BufRead>`, which
feels like it wouldn't be so great for performance. So instead, taking
the approach I did here is probably better - having a function that
accepts the `impl BufRead` and matching to use it.

# User-Facing Changes

- `from json --objects` no longer collects its input, and can be used
for large datasets or streams that produce values over time.

# Tests + Formatting
All passing.

explore cleanup: remove+move binary viewer config (#12920)
Small change, removing 4 more configuration options from `explore`'s
binary viewer:

1. `show_index`
2. `show_data`
3. `show_ascii`
4. `show_split`

These controlled whether the 3 columns in the binary viewer (index, hex
data, ASCII) and the pipe separator (`|`) in between them are shown. I
don't think we need this level of configurability until the `explore`
command is more mature, and maybe even not then; we can just show them
all.

I think it's very unlikely that anyone is using these configuration
points.

Also, the row offset (e.g. how many rows we have scrolled down) was
being stored in config/settings when it's arguably not config; more like
internal state of the binary viewer. I moved it to a more appropriate
location and renamed it.

Rewrite run_external.rs (#12921)
This PR is a complete rewrite of `run_external.rs`. The main goal of the
rewrite is improving readability, but it also fixes some bugs related to
argument handling and the PATH variable (fixes
https://github.com/nushell/nushell/issues/6011).

I'll discuss some technical details to make reviewing easier.

## Argument handling

Quoting arguments for external commands is hard. Like, *really* hard.
We've had more than a dozen issues and PRs dedicated to quoting
arguments (see Appendix) but the current implementation is still buggy.

Here's a demonstration of the buggy behavior:

```nu
let foo = "'bar'"
^touch $foo            # This creates a file named `bar`, but it should be `'bar'`
^touch ...[ "'bar'" ]  # Same
```

I'll describe how this PR deals with argument handling.

First, we'll introduce the concept of **bare strings**. Bare strings are
**string literals** that are either **unquoted** or **quoted by
backticks** [^1]. Strings within a list literal are NOT considered bare
strings, even if they are unquoted or quoted by backticks.

When a bare string is used as an argument to external process, we need
to perform tilde-expansion, glob-expansion, and inner-quotes-removal, in
that order. "Inner-quotes-removal" means transforming from
`--option="value"` into `--option=value`.

## `.bat` files and CMD built-ins

On Windows, `.bat` files and `.cmd` files are considered executable, but
they need `CMD.exe` as the interpreter. The Rust standard library
supports running `.bat` files directly and will spawn `CMD.exe` under
the hood (see
[documentation](https://doc.rust-lang.org/std/process/index.html#windows-argument-splitting)).
However, other extensions are not supported [^2].

Nushell also supports a selected number of CMD built-ins. The problem
with CMD is that it uses a different set of quoting rules. Correctly
quoting for CMD requires using
[Command::raw_arg()](https://doc.rust-lang.org/std/os/windows/process/trait.CommandExt.html#tymethod.raw_arg)
and manually quoting CMD special characters, on top of quoting from the
Nushell side. ~~I decided that this is too complex and chose to reject
special characters in CMD built-ins instead [^3]. Hopefully this will
not affact real-world use cases.~~ I've implemented escaping that works
reasonably well.

## `which-support` feature

The `which` crate is now a hard dependency of `nu-command`, making the
`which-support` feature essentially useless. The `which` crate is
already a hard dependency of `nu-cli`, and we should consider removing
the `which-support` feature entirely.

## Appendix

Here's a list of quoting-related issues and PRs in rough chronological
order.

* https://github.com/nushell/nushell/issues/4609
* https://github.com/nushell/nushell/issues/4631

[^1]: The idea that backtick-quoted strings act like bare strings was
introduced by Kubouch and briefly mentioned in [the language
reference](https://www.nushell.sh/lang-guide/chapters/strings_and_text.html#backtick-quotes).

[^2]: The documentation also said "running .bat scripts in this way may
be removed in the future and so should not be relied upon", which is
another reason to move away from this. But again, quoting for CMD is
hard.

[^3]: If anyone wants to try, the best resource I found on the topic is
[this](https://daviddeley.com/autohotkey/parameters/parameters.htm).

Implement streaming I/O for CSV and TSV commands (#12918)
# Description

Implements streaming for:

- `from csv`
- `from tsv`
- `to csv`
- `to tsv`

via the new string-typed ByteStream support.

# User-Facing Changes
Commands above. Also:

- `to csv` and `to tsv` now have `--columns <List(String)>`, to provide
the exact columns desired in the output. This is required for them to
have streaming output, because otherwise collecting the entire list is
necessary to determine the output columns. If we introduce
`TableStream`, this may become less necessary.

Add support for the ps command on FreeBSD, NetBSD, and OpenBSD (#12892)
# Description

I feel like it's a little sad that BSDs get to enjoy almost everything
other than the `ps` command, and there are some tests that rely on this
command, so I figured it would be fun to patch that and make it work.

The different BSDs have diverged from each other somewhat, but generally
have a similar enough API for reading process information via
`sysctl()`, with some slightly different args.

This supports FreeBSD with the `freebsd` module, and NetBSD and OpenBSD
with the `netbsd` module. OpenBSD is a fork of NetBSD and the interface
has some minor differences but many things are the same.

I had wanted to try to support DragonFlyBSD too, but their Rust version
in the latest release is only 1.72.0, which is too old for me to want to
try to compile rustc up to 1.77.2... but I will revisit this whenever
they do update it. Dragonfly is a fork of FreeBSD, so it's likely to be
more or less the same - I just don't want to enable it without testing
it.

Fixes #6862 (partially, we probably won't be adding `zfs list`)

# User-Facing Changes
`ps` added for FreeBSD, NetBSD, and OpenBSD.

# Tests + Formatting
The CI doesn't run tests for BSDs, so I'm not entirely sure if
everything was already passing before. (Frankly, it's unlikely.) But
nothing appears to be broken.

# After Submitting
- [ ] release notes?
- [ ] DragonflyBSD, whenever they do update Rust to something close
enough for me to try it

Add completer for std help (#12929)
# Description

While each of the `help <subcommands>` in `std` had completers, there
wasn't one for the main `help` command.

This adds all internals and custom commands (as with `help commands`) as
possible completions.

# User-Facing Changes

`help ` + <kbd>Tab</kbd> will now suggest completions for both the `help
<subcommands>` as well as all internal and custom commands.

# Tests + Formatting

Note: Cannot add tests for completion functions since they are
module-internal and not visible to test cases, that I can see.

explore: consolidate padding config, handle ByteStream, tweak naming+comments (#12915)
Some minor changes to `explore`, continuing on my mission to simplify
the command in preparation for a larger UX overhaul:

1. Consolidate padding configuration. I don't think we need separate
config points for the (optional) index column and regular data columns
in the normal pager, they can share padding configuration. Likewise, in
the binary viewer all 3 columns (index, data, ASCII) had their
left+right padding configured independently.
2. Update `explore` so we use the binary viewer for the new `ByteStream`
type. `cat foo.txt | into binary | explore` was not using the binary
viewer after the `ByteStream` changes.
3. Tweak the naming of a few helper functions, add a comment

I've put the changes in separate commits to make them easier to review.

Add string/binary type color to ByteStream (#12897)
# Description

This PR allows byte streams to optionally be colored as being
specifically binary or string data, which guarantees that they'll be
converted to `Binary` or `String` appropriately on `into_value()`,
making them compatible with `Type` guarantees. This makes them
significantly more broadly usable for command input and output.

There is still an `Unknown` type for byte streams coming from external
commands, which uses the same behavior as we previously did where it's a
string if it's UTF-8.

A small number of commands were updated to take advantage of this, just
to prove the point. I will be adding more after this merges.

# User-Facing Changes
- New types in `describe`: `string (stream)`, `binary (stream)`
- These commands now return a stream if their input was a stream:
  - `into binary`
  - `into string`
  - `bytes collect`
  - `str join`
  - `first` (binary)
  - `last` (binary)
  - `take` (binary)
  - `skip` (binary)
- Streams that are explicitly binary colored will print as a streaming
hexdump
  - example:
    ```nushell
    1.. | each { into binary } | bytes collect
    ```

# Tests + Formatting
I've added some tests to cover it at a basic level, and it doesn't break
anything existing, but I do think more would be nice. Some of those will
come when I modify more commands to stream.

# After Submitting
There are a few things I'm not quite satisfied with:

- **String trimming behavior.** We automatically trim newlines from
streams from external commands, but I don't think we should do this with
internal commands. If I call a command that happens to turn my string
into a stream, I don't want the newline to suddenly disappear. I changed
this to specifically do it only on `Child` and `File`, but I don't know
if this is quite right, and maybe we should bring back the old flag for
`trim_end_newline`
- **Known binary always resulting in a hexdump.** It would be nice to
have a `print --raw`, so that we can put binary data on stdout
explicitly if we want to. This PR doesn't change how external commands
work though - they still dump straight to stdout.

Otherwise, here's the normal checklist:

- [ ] release notes
- [ ] docs update for plugin protocol changes (added `type` field)

Make get_full_help take &dyn Command (#12903)
# Description
Changes `get_full_help` to take a `&dyn Command` instead of multiple
arguments (`&Signature`, `&Examples` `is_parser_keyword`). All of these
arguments can be gathered from a `Command`, so there is no need to pass
the pieces to `get_full_help`.

`--help` is used on a command.

Use CommandType in more places (#12832)
# Description
Kind of a vague title, but this PR does two main things:
1. Rather than overriding functions like `Command::is_parser_keyword`,
this PR instead changes commands to override `Command::command_type`.
The `CommandType` returned by `Command::command_type` is then used to
automatically determine whether `Command::is_parser_keyword` and the
other `is_{type}` functions should return true. These changes allow us
to remove the `CommandType::Other` case and should also guarantee than
only one of the `is_{type}` functions on `Command` will return true.
2. Uses the new, reworked `Command::command_type` function in the `scope
commands` and `which` commands.


# User-Facing Changes
- Breaking change for `scope commands`: multiple columns (`is_builtin`,
`is_keyword`, `is_plugin`, etc.) have been merged into the `type`
column.
- Breaking change: the `which` command can now report `plugin` or
`keyword` instead of `built-in` in the `type` column. It may also now
report `external` instead of `custom` in the `type` column for known
`extern`s.

Preserve metadata in more places (#12848)
# Description
This PR makes some commands and areas of code preserve pipeline
metadata. This is in an attempt to make the issue described in #12599
and #9456 less likely to occur. That is, reading and writing to the same
file in a pipeline will result in an empty file. Since we preserve
metadata in more places now, there will be a higher chance that we
successfully detect this error case and abort the pipeline.

collect: don't require a closure (#12788)
# Description

This changes the `collect` command so that it doesn't require a closure.
Still allowed, optionally.

Before:

```nushell
open foo.json | insert foo bar | collect { save -f foo.json }
```

After:

```nushell
open foo.json | insert foo bar | collect | save -f foo.json
```

The closure argument isn't really necessary, as collect values are also
supported as `PipelineData`.

# User-Facing Changes
- `collect` command changed

# Tests + Formatting
Example changed to reflect.

# After Submitting
- [ ] release notes
- [ ] we may want to deprecate the closure arg?

Fix the way the output of table is printed in print() (#12895)
# Description

Forgot that I fixed this already on my branch, but when printing without

allow define it as a variable inside closure (#12888)
# Description
Fixes: #12690 

The issue is happened after
https://github.com/nushell/nushell/pull/12056 is merged. It will raise
error if user doesn't supply required parameter when run closure with
do.
And parser adds a `$it` parameter when parsing closure or block
expression.

I believe the previous behavior is because we allow such syntax on
previous version(0.44):
```nushell
let x = { print $it }
```
But it's no longer allowed after 0.60.  So I think they can be removed.

# User-Facing Changes
```nushell
let tmp = {
  let it = 42
  print $it
}

do -c $tmp
```
should be possible again.

Add Span merging functions (#12511)
# Description
This PR adds a few functions to `Span` for merging spans together:
- `Span::append`: merges two spans that are known to be in order.
- `Span::concat`: returns a span that encompasses all the spans in a
slice. The spans must be in order.
- `Span::merge`: merges two spans (no order necessary).
- `Span::merge_many`: merges an iterator of spans into a single span (no
order necessary).

These are meant to replace the free-standing `nu_protocol::span`
function.

The spans in a `LiteCommand` (the `parts`) should always be in order
based on the lite parser and lexer. So, the parser code sees the most
usage of `Span::append` and `Span::concat` where the order is known. In
other code areas, `Span::merge` and `Span::merge_many` are used since
the order between spans is often not known.

Replace ExternalStream with new ByteStream type (#12774)
# Description
This PR introduces a `ByteStream` type which is a `Read`-able stream of
bytes. Internally, it has an enum over three different byte stream
sources:
```rust
pub enum ByteStreamSource {
    Read(Box<dyn Read + Send + 'static>),
    File(File),
    Child(ChildProcess),
}
```

This is in comparison to the current `RawStream` type, which is an
`Iterator<Item = Vec<u8>>` and has to allocate for each read chunk.

Currently, `PipelineData::ExternalStream` serves a weird dual role where
it is either external command output or a wrapper around `RawStream`.
`ByteStream` makes this distinction more clear (via `ByteStreamSource`)
and replaces `PipelineData::ExternalStream` in this PR:
```rust
pub enum PipelineData {
    Empty,
    Value(Value, Option<PipelineMetadata>),
    ListStream(ListStream, Option<PipelineMetadata>),
    ByteStream(ByteStream, Option<PipelineMetadata>),
}
```

The PR is relatively large, but a decent amount of it is just repetitive
changes.

This PR fixes #7017, fixes #10763, and fixes #12369.

This PR also improves performance when piping external commands. Nushell
should, in most cases, have competitive pipeline throughput compared to,
e.g., bash.
| Command | Before (MB/s) | After (MB/s) | Bash (MB/s) |
| -------------------------------------------------- | -------------:|
------------:| -----------:|
| `throughput \| rg 'x'` | 3059 | 3744 | 3739 |
| `throughput \| nu --testbin relay o> /dev/null` | 3508 | 8087 | 8136 |

# User-Facing Changes
- This is a breaking change for the plugin communication protocol,
because the `ExternalStreamInfo` was replaced with `ByteStreamInfo`.
Plugins now only have to deal with a single input stream, as opposed to
the previous three streams: stdout, stderr, and exit code.
- The output of `describe` has been changed for external/byte streams.
- Temporary breaking change: `bytes starts-with` no longer works with
byte streams. This is to keep the PR smaller, and `bytes ends-with`
already does not work on byte streams.
- If a process core dumped, then instead of having a `Value::Error` in
the `exit_code` column of the output returned from `complete`, it now is
a `Value::Int` with the negation of the signal number.

# After Submitting
- Update docs and book as necessary
- Release notes (e.g., plugin protocol changes)
- Adapt/convert commands to work with byte streams (high priority is
`str length`, `bytes starts-with`, and maybe `bytes ends-with`).
- Refactor the `tee` code, Devyn has already done some work on this.

Remove stack debug assert (#12861)
# Description
In order for `Stack::unwrap_unique` to work as intended, we currently
manually track all references to the parent stack and ensure that they
are cleared before calling `Stack::unwrap_unique` in the REPL. We also
only call `Stack::unwrap_unique` after all code from the current REPL
entry has finished executing. Since `Value`s cannot store `Stack`
references, then this should have worked in theory. However, we forgot
to account for threads. `run-external` (and maybe the plugin writers)
can spawn threads that clone the `Stack`, holding on to references of
the parent stack. These threads are not waited/joined upon, and so may
finish after the eval has already returned. This PR removes the
`Stack::unwrap_unique` function and associated debug assert that was
[causing
panics](https://gist.github.com/cablehead/f3d2608a1629e607c2d75290829354f7)
like @cablehead found.

# After Submitting
Make values cheaper to clone as a more robust solution to the
performance issues with cloning the stack.

make better messages for incomplete string (#12868)
# Description
Fixes: #12795

The issue is caused by an empty position of `ParseError::UnexpectedEof`.
So no detailed message is displayed.
To fix the issue, I adjust the start of span to `span.end - 1`. In this
way, we can make sure that it never points to an empty position.

After lexing item, I also reorder the unclosed character checking . Now
it will be checking unclosed opening delimiters first.

There was a question in Discord today about how to remove empty rows

Add Stack::stdout_file and Stack::stderr_file to capture stdout/-err of external commands (#12857)
# Description
In this PR I added two new methods to `Stack`, `stdout_file` and
`stderr_file`. These two modify the inner `StackOutDest` and set a
`File` into the `stdout` and `stderr` respectively. Different to the
`push_redirection` methods, these do not require to hold a guard up all
the time but require ownership of the stack.

This is primarly useful for applications that use `nu` as a language but
not the `nushell`.

This PR replaces my first attempt #12851 to add a way to capture
stdout/-err of external commands. Capturing the stdout without having to
write into a file is possible with crates like
[`os_pipe`](https://docs.rs/os_pipe), an example for this is given in
the doc comment of the `stdout_file` command and can be executed as a
doctest (although it doesn't validate that you actually got any data).

This implementation takes `File` as input to make it easier to implement
on different operating systems without having to worry about
`OwnedHandle` or `OwnedFd`. Also this doesn't expose any use `os_pipe`
to not leak its types into this API, making it depend on it.

As in my previous attempt, @IanManske guided me here.

# User-Facing Changes
This change has no effect on `nushell` and therefore no user-facing
changes.

# Tests + Formatting
This only exposes a new way of using already existing code and has
therefore no further testing. The doctest succeeds on my machine at
least (x86 Windows, 64 Bit).

Add example and search term for 'repeat' to the fill command (#12844)
# Description

It's commonly forgotten or overlooked that a lot of `std repeat`
functionality can be handled with the built-in `fill`. Added 'repeat` as
a search term for `fill` to improve discoverability.

Also replaced one of the existing examples with one `fill`ing an empty
string, a la `repeat`. There were 6 examples already, and 3 of them
pretty much were variations on the same theme, so I repurposed one of
those rather than adding a 7th.

# Description
This PR resolves an inconsistency between different `str` subcommands,
notably `str contains`, `str starts-with` and `str ends-with`. Only the
`str contains` command has the `--not` flag and a desicion was made in
this #12781 PR to remove the `--not` flag and use the `not` operator
instead.

Before:
`"blob" | str contains --not o`
After:
`not ("blob" | str contains o)` OR `"blob" | str contains o | not $in`

> Note, you can currently do all three, but the first will be broken
after this PR is merged.

Implement PWD recovery (#12779)
This PR has two parts. The first part is the addition of the
`Stack::set_pwd()` API. It strips trailing slashes from paths for
convenience, but will reject otherwise bad paths, leaving PWD in a good
state. This should reduce the impact of faulty code incorrectly trying
to set PWD.
(https://github.com/nushell/nushell/pull/12760#issuecomment-2095393012)

The second part is implementing a PWD recovery mechanism. PWD can become
bad even when we did nothing wrong. For example, Unix allows you to
remove any directory when another process might still be using it, which
means PWD can just "disappear" under our nose. This PR makes it possible
to use `cd` to reset PWD into a good state. Here's a demonstration:

```sh
mkdir /tmp/foo
cd /tmp/foo

# delete "/tmp/foo" in a subshell, because Nushell is smart and refuse to delete PWD
nu -c 'cd /; rm -r /tmp/foo'

ls          # Error:   × $env.PWD points to a non-existent directory
            # help: Use `cd` to reset $env.PWD into a good state

cd /
pwd         # prints /
```

Also, auto-cd should be working again.

Shrink Value by boxing Range/Closure (#12784)
# Description
On 64-bit platforms the current size of `Value` is 56 bytes. The
limiting variants were `Closure` and `Range`. Boxing the two reduces the
size of Value to 48 bytes. This is the minimal size possible with our
current 16-byte `Span` and any 24-byte `Vec` container which we use in
several variants. (Note the extra full 8-bytes necessary for the
discriminant or other smaller values due to the 8-byte alignment of
`usize`)

This is leads to a size reduction of ~15% for `Value` and should overall
be beneficial as both `Range` and `Closure` are rarely used compared to
the primitive types or even our general container types.

# User-Facing Changes
Less memory used, potential runtime benefits.

This PR adds a new `echo` command to the `nu_plugin_example` plugin that
simply [streams all of its input to its

cleanup osc calls for shell_integration (#12810)
# Description

This PR is a continuation of #12629 and meant to address [Reilly's
stated
issue](https://github.com/nushell/nushell/pull/12629#issuecomment-2099660609).

With this PR, nushell should work more consistently with WezTerm on
Windows. However, that means continued scrolling with typing if osc133
is enabled. If it's possible to run WezTerm inside of vscode, then
having osc633 enabled will also cause the display to scroll with every
character typed. I think the cause of this is that reedline paints the
entire prompt on each character typed. We need to figure out how to fix
that, but that's in reedline.

For my purposes, I keep osc133 and osc633 set to true and don't use
WezTerm on Windows.

Thanks @rgwood for reporting the issue. I found several logic errors.
It's often good to come back to PRs and look at them with fresh eyes. I
think this is pretty close to logically correct now. However, I'm
approaching burn out on ansi escape codes so i could've missed
something.

Kudos to [escape-artist](https://github.com/rgwood/escape-artist) for
helping me debug an ansi escape codes that are actually being sent to
the terminal. It was an invaluable tool.

Make the message when running a plugin exe directly clearer (#12806)
# Description

This changes the message that shows up when running a plugin executable
directly rather than as a plugin to direct the user to run `plugin add
--help`, which should have enough information to figure out what's going
on. The message previously just vaguely suggested that the user needs to
run the plugin "from within Nushell", which is not really enough - it
has to be added with `plugin add` to be used as a plugin.

Also fix docs for `plugin add` to mention `plugin use` rather than
`register` (oops)

Migrate to a new PWD API (part 2) (#12749)
Refer to #12603 for part 1.

We need to be careful when migrating to the new API, because the new API
has slightly different semantics (PWD can contain symlinks). This PR
handles the "obviously safe" part of the migrations. Namely, it handles
two specific use cases:

* Passing PWD into `canonicalize_with()`
* Passing PWD into `EngineState::merge_env()`

The first case is safe because symlinks are canonicalized away. The
second case is safe because `EngineState::merge_env()` only uses PWD to
call `std::env::set_current_dir()`, which shouldn't affact Nushell. The
commit message contains detailed stats on the updated files.

Because these migrations touch a lot of files, I want to keep these PRs
small to avoid merge conflicts.

Add sys subcommands (#12747)
# Description
Adds subcommands to `sys` corresponding to each column of the record
returned by `sys`. This is to alleviate the fact that `sys` now returns
a regular record, meaning that it must compute every column which might
take a noticeable amount of time. The subcommands, on the other hand,
only need to compute and return a subset of the data which should be
much faster. In fact, it should be as fast as before, since this is how
the lazy record worked (it would compute only each column as necessary).

I choose to add subcommands instead of having an optional cell-path
parameter on `sys`, since the cell-path parameter would:
- increase the code complexity (can access any value at any row or
nested column)
- prevents discovery with tab-completion
- hinders type checking and allows users to pass potentially invalid
columns

# User-Facing Changes
Deprecates `sys` in favor of the new `sys` subcommands.

Polars lazy refactor (#12669)
This moves to predominantly supporting only lazy dataframes for most
operations. It removes a lot of the type conversion between lazy and
eager dataframes based on what was inputted into the command.

For the most part the changes will mean:
* You will need to run `polars collect` after performing operations
* The into-lazy command has been removed as it is redundant.
* When opening files a lazy frame will be outputted by default if the
reader supports lazy frames

Allow ls works inside dir with [] brackets (#12625)
# Description
Fixes: #12429

To fix the issue, we need to pass the `input pattern` itself to
`glob_from` function, but currently on latest main, nushell pass
`expanded path of input pattern` to `glob_from` function.
It causes globbing failed if expanded path includes `[]` brackets.

It's a pity that I have to duplicate `nu_engine::glob_from` function
into `ls`, because `ls` might convert from `NuGlob::NotExpand` to
`NuGlob::Expand`, in that case, `nu_engine::glob_from` won't work if
user want to ls for a directory which includes tilde:
```
mkdir "~abc"
ls "~abc"
```
So I need to duplicate `glob_from` function and pass original
`expand_tilde` information.

ListStream touchup (#12524)
# Description

Does some misc changes to `ListStream`:
- Moves it into its own module/file separate from `RawStream`.
- `ListStream`s now have an associated `Span`.
- This required changes to `ListStreamInfo` in `nu-plugin`. Note sure if
this is a breaking change for the plugin protocol.
- Hides the internals of `ListStream` but also adds a few more methods.
- This includes two functions to more easily alter a stream (these take
a `ListStream` and return a `ListStream` instead of having to go through
the whole `into_pipeline_data(..)` route).
  -  `map`: takes a `FnMut(Value) -> Value`
  - `modify`: takes a function to modify the inner stream.

Refactor flattening to reduce intermediate allocations (#12756)
# Description
Our current flattening code creates a bunch of intermediate `Vec`s for
each function call. These intermediate `Vec`s are then usually appended
to the current `output` `Vec`. By instead passing a mutable reference of
the `output` `Vec` to each flattening function, this `Vec` can be
reused/appended to directly thereby eliminating the need for
intermediate `Vec`s in most cases.

Fix PWD cannot point to root paths (#12761)
PR https://github.com/nushell/nushell/pull/12603 made it so that PWD can
never contain a trailing slash. However, a root path (such as `/` or

doesn't work.

quickly before anyone else finds out...

This is a rewrite for some parts of the recursive completion system. The
Rust `std::path` structures often ignores things like a trailing `.`
because for a complete path, it implies the current directory. We are
replacing the use of some of these structs for Strings.

A side effect is the slashes being normalized in Windows. For example if
we were to type `foo/bar/b`, it would complete it to `foo\bar\baz`
because a backward slash is the main separator in windows.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

Relative paths are preserved. `..`s in the paths won't eagerly show
completions from the parent path. For example, `asd/foo/../b` will now
complete to `asd/foo/../bar` instead of `asd/bar`.

add more tests to the polars plugin (#12719)
# Description

I added some more tests to our mighty `polars` ~~, yet I don't know how
to add expected results in some of them. I would like to ask for help.~~

~~My experiments are in the last commit: [polars:
experiments](f7e5e72019).
Without those experiments `cargo test` goes well.~~
 
UPD. I moved out my unsuccessful test experiments into a separate
[branch](https://github.com/maxim-uvarov/nushell/blob/polars-tests-broken2/).
So, this branch seems ready for a merge.

@ayax79, maybe you'll find time for me please? It's not urgent for sure.

P.S. I'm very new to git. Please feel free to give me any suggestions on
how I should use it better

Report errors that occur on file operations in ls (#12033)
Currently errors just create empty entries inside of resulting
dataframes.

This changeset is meant to help debug #12004, though generally speaking
I do think it's worth having ways to make errors be visible in this kind
of pipeline be visible

An example of what this looks like

Migrate to a new PWD API (#12603)
This is the first PR towards migrating to a new `$env.PWD` API that
returns potentially un-canonicalized paths. Refer to PR #12515 for
motivations.

## New API: `EngineState::cwd()`

The goal of the new API is to cover both parse-time and runtime use
case, and avoid unintentional misuse. It takes an `Option<Stack>` as
argument, which if supplied, will search for `$env.PWD` on the stack in
additional to the engine state. I think with this design, there's less
confusion over parse-time and runtime environments. If you have access
to a stack, just supply it; otherwise supply `None`.

## Deprecation of other PWD-related APIs

Other APIs are re-implemented using `EngineState::cwd()` and properly
documented. They're marked deprecated, but their behavior is unchanged.
Unused APIs are deleted, and code that accesses `$env.PWD` directly
without using an API is rewritten.

Deprecated APIs:

* `EngineState::current_work_dir()`
* `StateWorkingSet::get_cwd()`
* `env::current_dir()`
* `env::current_dir_str()`
* `env::current_dir_const()`
* `env::current_dir_str_const()`

Other changes:

* `EngineState::get_cwd()` (deleted)
* `StateWorkingSet::list_env()` (deleted)
* `repl::do_run_cmd()` (rewritten with `env::current_dir_str()`)

## `cd` and `pwd` now use logical paths by default

This pulls the changes from PR #12515. It's currently somewhat broken
because using non-canonicalized paths exposed a bug in our path
normalization logic (Issue #12602). Once that is fixed, this should
work.

## Future plans

This PR needs some tests. Which test helpers should I use, and where
should I put those tests?

I noticed that unquoted paths are expanded within `eval_filepath()` and
`eval_directory()` before they even reach the `cd` command. This means
every paths is expanded twice. Is this intended?

Once this PR lands, the plan is to review all usages of the deprecated
APIs and migrate them to `EngineState::cwd()`. In the meantime, these
usages are annotated with `#[allow(deprecated)]` to avoid breaking CI.

Upgrade to interprocess 2.0.0 (#12729)
# Description

This fixes #12724. NetBSD confirmed to work with this change.

The update also behaves a bit better in some ways - it automatically
unlinks and reclaims sockets on Unix, and doesn't try to flush/sync the
socket on Windows, so I was able to remove that platform-specific logic.

They also have a way to split the socket so I could just use one socket
now, but I haven't tried to do that yet. That would be more of a
breaking change but I think it's more straightforward.

Flush on every plugin Data message (#12728)
# Description

This helps to ensure data produced on a stream is immediately available
to the consumer of the stream. The BufWriter introduced for performance
reasons in 0.93 exposed the behavior that data messages wouldn't make it
to the other side until they filled the buffer in @cablehead's
[`nu_plugin_from_sse`](https://github.com/cablehead/nu_plugin_from_sse).

I had originally not flushed on every `Data` message because I figured
that it isn't really critical that the other side sees those messages
immediately, since they're not used for control and they are flushed
when waiting for acknowledgement or when the buffer is too full anyway.

Increasing the amount of data that can be sent with a single underlying
write increases performance, but this interferes with some plugins that
want to use streams in a more real-time way. In the future I would like
to make this configurable, maybe even per-command, so that a command can
decide what the priority is. But for now I think this is reasonable.

In the worst case, this decreases performance by about 40%, when sending
very small values (just numbers). But for larger values, this PR
actually increases performance by about 20%, because I've increased the
buffer size about 2x to 16,384 bytes. The previous value of 8,192 bytes
was too small to fit a full buffer coming from an external command, so
doubling it makes sense, and now a write of a buffer from an external
command can be done in exactly one write call, which I think makes
sense. I'm doing this at the same time because flushing each data
message would make it very likely that each individual data message from
an external stream would require exactly two writes rather than
approximately one (amortized).

Again, hopefully the tradeoff isn't too bad, and if it is I'll just make
it configurable.

- Performance of plugin streams will be a bit different
- Plugins that expect to send streams in real-time will work again

overhaul shell_integration to enable individual control over ansi escape sequences (#12629)
# Description

This PR overhauls the shell_integration system by allowing individual
control over which ansi escape sequences are used. As we continue to
broaden our support for more ansi escape sequences, we can't really have
an all-or-nothing strategy. Some ansi escapes cause problems in certain
operating systems or terminals. We should allow the user to choose which
escapes they want.

TODO:
* Gather feedback
* Should osc7, osc9_9 and osc633p be mutually exclusive?
* Is the naming convention for these settings too nerdy osc2, osc7, etc?

closes #11301

# User-Facing Changes
shell_integration is no longer a boolean value. This is what is
supported in the default_config.nu
```nushell
  shell_integration: {
    # osc2 abbreviates the path if in the home_dir, sets the tab/window title, shows the running command in the tab/window title
    osc2: true
    # osc7 is a way to communicate the path to the terminal, this is helpful for spawning new tabs in the same directory
    osc7: true
    # osc8 is also implemented as the deprecated setting ls.show_clickable_links, it shows clickable links in ls output if your terminal supports it
    osc8: true
    # osc9_9 is from ConEmu and is starting to get wider support. It's similar to osc7 in that it communicates the path to the terminal
    osc9_9: false
    # osc133 is several escapes invented by Final Term which include the supported ones below.
    # 133;A - Mark prompt start
    # 133;B - Mark prompt end
    # 133;C - Mark pre-execution
    # 133;D;exit - Mark execution finished with exit code
    # This is used to enable terminals to know where the prompt is, the command is, where the command finishes, and where the output of the command is
    osc133: true
    # osc633 is closely related to osc133 but only exists in visual studio code (vscode) and supports their shell integration features
    # 633;A - Mark prompt start
    # 633;B - Mark prompt end
    # 633;C - Mark pre-execution
    # 633;D;exit - Mark execution finished with exit code
    # 633;E - NOT IMPLEMENTED - Explicitly set the command line with an optional nonce
    # 633;P;Cwd=<path> - Mark the current working directory and communicate it to the terminal
    # and also helps with the run recent menu in vscode
    osc633: true
    # reset_application_mode is escape \x1b[?1l and was added to help ssh work better
    reset_application_mode: true

add raw-string literal support (#9956)
# Description

This PR adds raw string support by using `r#` at the beginning of single
quoted strings and `#` at the end.

Notice that escapes do not process, even within single quotes,
parentheses don't mean anything, $variables don't mean anything. It's
just a string.
```nushell
❯ echo r#'one\ntwo (blah) ($var)'#
one\ntwo (blah) ($var)
```
Notice how they work without `echo` or `print` and how they work without
carriage returns.
```nushell
❯ r#'adsfa'#
adsfa
❯ r##"asdfa'@qpejq'##
asdfa'@qpejq
❯ r#'asdfasdfasf
∙ foqwejfqo@'23rfjqf'#
```
They also have a special configurable color in the repl. (use single
quotes though)

![image](https://github.com/nushell/nushell/assets/343840/8780e21d-de4c-45b3-9880-2425f5fe10ef)

They should work like rust raw literals and allow `r##`, `r###`,
`r####`, etc, to help with having one or many `#`'s in the middle of
your raw-string.

They should work with `let` as well.

```nushell
r#'some\nraw\nstring'# | str upcase
```

explore: adopt anyhow, support CustomValue, remove help system (#12692)
This PR:
1. Adds basic support for `CustomValue` to `explore`. Previously `open
foo.db | explore` didn't really work, now we "materialize" the whole
database to a `Value` before loading it
2. Adopts `anyhow` for error handling in `explore`. Previously we were
kind of rolling our own version of `anyhow` by shoving all errors into a
`std::io::Error`; I think this is much nicer. This was necessary because
as part of 1), collecting input is now fallible...
3. Removes a lot of `explore`'s fancy command help system.
- Previously each command (`:help`, `:try`, etc.) had a sophisticated
help system with examples etc... but this was not very visible to users.
You had to know to run `:help :try` or view a list of commands with
`:help :`
- As discussed previously, we eventually want to move to a less modal
approach for `explore`, without the Vim-like commands. And so I don't
think it's worth keeping this command help system around (it's
intertwined with other stuff, and making these changes would have been
harder if keeping it).
4. Rename the `--reverse` flag to `--tail`. The flag scrolls to the end
of the data, which IMO is described better by "tail"
5. Does some renaming+commenting to clear up things I found difficult to
understand when navigating the `explore` code


I initially thought 1) would be just a few lines, and then this PR blew
up into much more extensive changes 😅


## Before
The whole database was being displayed as a single Nuon/JSON line 🤔 

![image](https://github.com/nushell/nushell/assets/26268125/6383f43b-fdff-48b4-9604-398438ad1499)


## After
The database gets displayed like a record

![image](https://github.com/nushell/nushell/assets/26268125/2f00ed7b-a3c4-47f4-a08c-98d07efc7bb4)


## Future work

It is sort of annoying that we have to load a whole SQLite database into
memory to make this work; it will be impractical for large databases.
I'd like to explore improvements to `CustomValue` that can make this
work more efficiently.

Make bytes build accept integer values as individual bytes (#12685)
# Description
This creates an option for building binary data from byte integers.
Previously I think you could only do this by formatting the integers to
hex and using `decode hex`.

One potentially confusing thing is that this is different from the `into
binary` behavior. But since this doesn't support any of the other `into
binary` behaviors, it might be okay.

# User-Facing Changes
- `bytes build` accepts single byte arguments as integers

Change environment variables to be case-preserving (#12701)
This PR changes `$env` to be **case-preserving** instead of
case-sensitive. That is, it preserves the case of the environment
variable when it is first assigned, but subsequent retrieval and update
ignores the case.

Notably, both `$env.PATH` and `$env.Path` can now be used to read or set
the environment variable, but child processes will always see the
correct case based on the platform.

Fixes #11268.

---

This feature was surprising simple to implement, because most of the
infrastructure to support case-insensitive cell path access already
exists. The `get` command extracts data using a cell path in a
case-insensitive way (!), but accepts a `--sensitive` flag. (I think
this should be flipped around?)

Fix missing local socket feature (#12698)
# Description

So sorry to do this during the pre-release freeze, but my plugin crate
split PR broke local socket mode, because `nu-plugin-protocol` didn't
have the compile feature to advertise the `LocalSocket` protocol
feature.

This is a very simple, configuration-only bugfix that I think really
needs to be merged before the release, or else local socket mode won't
work at all.

# Tests + Formatting

There's an oversight in my testing that caused this to not be caught:
the engine really did have the feature, but it just wasn't advertising
it, so for `stress_internals` it was still able to use it successfully.
Post-release I'll try to make sure this is properly handled somehow.

Split the plugin crate (#12563)
# Description

This breaks `nu-plugin` up into four crates:

- `nu-plugin-protocol`: just the type definitions for the protocol, no
I/O. If someone wanted to wire up something more bare metal, maybe for
async I/O, they could use this.
- `nu-plugin-core`: the shared stuff between engine/plugin. Less stable
interface.
- `nu-plugin-engine`: everything required for the engine to talk to
plugins. Less stable interface.
- `nu-plugin`: everything required for the plugin to talk to the engine,
what plugin developers use. Should be the most stable interface.

No changes are made to the interface exposed by `nu-plugin` - it should
all still be there. Re-exports from `nu-plugin-protocol` or
`nu-plugin-core` are used as required. Plugins shouldn't ever have to
use those crates directly.

This should be somewhat faster to compile as `nu-plugin-engine` and
`nu-plugin` can compile in parallel, and the engine doesn't need
`nu-plugin` and plugins don't need `nu-plugin-engine` (except for test
support), so that should reduce what needs to be compiled too.

The only significant change here other than splitting stuff up was to
break the `source` out of `PluginCustomValue` and create a new
`PluginCustomValueWithSource` type that contains that instead. One bonus
of that is we get rid of the option and it's now more type-safe, but it
also means that the logic for that stuff (actually running the plugin
for custom value ops) can live entirely within the `nu-plugin-engine`
crate.

# User-Facing Changes
- New crates.
- Added `local-socket` feature for `nu` to try to make it possible to
compile without that support if needed.

Fix inconsistent print behavior (#12675)
# Description

I found a bunch of issues relating to the specialized reimplementation
of `print()` that's done in `nu-cli` and it just didn't seem necessary.
So I tried to unify the behavior reasonably. `PipelineData::print()`
already handles the call to `table` and it even has a `no_newline`
option.

One of the most major issues before was that we were using the value
iterator, and then converting to string, and then printing each with
newlines. This doesn't work well for an external stream, because its
iterator ends up creating `Value::binary()` with each buffer... so we
were doing lossy UTF-8 conversion on those and then printing them with
newlines, which was very weird:


![Screenshot_2024-04-26_02-02-29](https://github.com/nushell/nushell/assets/10729/131c2224-08ee-4582-8617-6ecbb3ce8da5)

You can see the random newline inserted in a break between buffers, but
this would be even worse if it were on a multibyte UTF-8 character. You
can produce this by writing a large amount of text to a text file, and
then doing `nu -c 'open file.txt'` - in my case I just wrote `^find .`;
it just has to be large enough to trigger a buffer break.

Using `print()` instead led to a new issue though, because it doesn't
abort on errors. This is so that certain commands can produce a stream
of errors and have those all printed. There are tests for e.g. `rm` that
depend on this behavior. I assume we want to keep that, so instead I
made my target `BufferedReader`, and had that fuse closed if an error
was encountered. I can't imagine we want to keep reading from a wrapped
I/O stream if an error occurs; more often than not the error isn't going
to magically resolve itself, it's not going to be a different error each
time, and it's just going to lead to an infinite stream of the same
error.

The test that broke without that was `open . | lines`, because `lines`
doesn't fuse closed on error. But I don't know if it's expected or not
for it to do that, so I didn't target that.

I think this PR makes things better but I'll keep looking for ways to
improve on how errors and streams interact, especially trying to
eliminate cases where infinite error loops can happen.

# User-Facing Changes
- **Breaking**: `BufferedReader` changes + no more public fields
- A raw I/O stream from e.g. `open` won't produce infinite errors
anymore, but I consider that to be a plus
- the implicit `print` on script output is the same as the normal one
now

Everything passes but I didn't add anything specific.

Add plugin error propagation on write/flush (#12670)
# Description
Yet another attempt to fix the `stress_internals::test_wrong_version()`
test...

This time I think it's probably because we are getting a broken pipe
write error when we try to send `Hello` or perhaps something after it,
because the pipe has already been closed by the reader when it saw the
invalid version. In that case, an error should be available in state. It
probably makes more sense to send that back to the user rather than an
unhelpful I/O error.

Msgpack commands (#12664)
# Description

I thought about bringing `nu_plugin_msgpack` in, but that is MPL with a
clause that prevents other licenses, so rather than adapt that code I
decided to take a crack at just doing it straight from `rmp` to `Value`
without any `rmpv` in the middle. It seems like it's probably faster,
though I can't say for sure how much with the plugin overhead.

@IanManske I started on a `Read` implementation for `RawStream` but just
specialized to `from msgpack` here, but I'm thinking after release maybe
we can polish it up and make it a real one. It works!

# User-Facing Changes

Shrink the size of Expr (#12610)
# Description
Continuing from #12568, this PR further reduces the size of `Expr` from
64 to 40 bytes. It also reduces `Expression` from 128 to 96 bytes and
`Type` from 32 to 24 bytes.

This was accomplished by:
- for `Expr` with multiple fields (e.g., `Expr::Thing(A, B, C)`),
merging the fields into new AST struct types and then boxing this struct
(e.g. `Expr::Thing(Box<ABC>)`).
- replacing `Vec<T>` with `Box<[T]>` in multiple places. `Expr`s and
`Expression`s should rarely be mutated, if at all, so this optimization
makes sense.

By reducing the size of these types, I didn't notice a large performance
improvement (at least compared to #12568). But this PR does reduce the
memory usage of nushell. My config is somewhat light so I only noticed a
difference of 1.4MiB (38.9MiB vs 37.5MiB).

Fix (and test) for a deadlock that can happen while waiting for protocol info (#12633)
# Description

The local socket PR introduced a `Waitable` type, which could either
hold a value or be waited on until a value is available. Unlike a
channel, it would always return that value once set.

However, one issue with this design was that there was no way to detect
whether a value would ever be written. This splits the writer into a
different type `WaitableMut`, so that when it is dropped, waiting
threads can fail (because they'll never get a value).

Fix error message propagation on plugin call failure (#12632)
# Description

This should fix the sometimes failing wrong version test for
stress_internals.

The plugin interface state stores an error if some kind of critical
error happened, and this error should be propagated to any future
operations on the interface, but this wasn't being propagated to plugin
calls that were already waiting.

During plugin registration, the wrong version error needs to be received
as a response to the `get_signature()` to show up properly, but this
would only happen if `get_signature()` started after the `Hello` was
already received and processed. That would be a race condition, which
this commit solves.

Deprecate register and add plugin use (#12607)
# Description

Adds a new keyword, `plugin use`. Unlike `register`, this merely loads
the signatures from the plugin cache file. The file is configurable with
the `--plugin-config` option either to `nu` or to `plugin use` itself,
just like the other `plugin` family of commands. At the REPL, one might
do this to replace `register`:

```nushell
> plugin add ~/.cargo/bin/nu_plugin_foo
> plugin use foo
```

This will not work in a script, because `plugin use` is a keyword and
`plugin add` does not evaluate at parse time (intentionally). This means
we no longer run random binaries during parse.

The `--plugins` option has been added to allow running `nu` with certain
plugins in one step. This is used especially for the `nu_with_plugins!`
test macro, but I'd imagine is generally useful. The only weird quirk is
that it has to be a list, and we don't really do this for any of our
other CLI args at the moment.

`register` now prints a deprecation parse warning.

This should fix #11923, as we now have a complete alternative to
`register`.

# User-Facing Changes

- Add `plugin use` command
- Deprecate `register`
- Add `--plugins` option to `nu` to replace a common use of `register`

# Tests + Formatting

I think I've tested it thoroughly enough and every existing test passes.
Testing nu CLI options and alternate config files is a little hairy and
I wish there were some more generic helpers for this, so this will go on
my TODO list for refactoring.

Add ErrSpan extension trait for Result (#12626)
# Description
This adds an extension trait to `Result` that wraps errors in `Spanned`,
saving the effort of calling `.map_err(|err| err.into_spanned(span))`
every time. This will hopefully make it even more likely that someone
will want to use a spanned `io::Error` and make it easier to remove the
impl for `From<io::Error> for ShellError` because that doesn't have span
information.

The panic can happened if we pipe a variable to a custom command which

Refactor using ClosureEval types (#12541)
# Description
Adds two new types in `nu-engine` for evaluating closures: `ClosureEval`
and `ClosureEvalOnce`. This removed some duplicate code and centralizes
our logic for setting up, running, and cleaning up closures. For
example, in the future if we are able to reduce the cloning necessary to
run a closure, then we only have to change the code related to these
types.

`ClosureEval` and `ClosureEvalOnce` are designed with a builder API.
`ClosureEval` is used to run a closure multiple times whereas
`ClosureEvalOnce` is used for a one-shot closure.

# User-Facing Changes
Should be none, unless I messed up one of the command migrations.
Actually, this will fix any unreported environment bugs for commands
that didn't reset the env after running a closure.

Make the same file error more likely to appear (#12601)
# Description
When saving to a file we currently try to check if the data source in
the pipeline metadata is the same as the file we are saving to. If so,
we create an error, since reading and writing to a file at the same time
is currently not supported/handled gracefully. However, there are still
a few instances where this error is not properly triggered, and so this
PR attempts to reduce these cases. Inspired by #12599.

# Tests + Formatting
Added a few tests.

# After Submitting
Some commands still do not properly preserve metadata (e.g., `str trim`)
and so prevent us from detecting this error.

Added commands for working with the plugin cache. (#12576)
# Description
This pull request provides three new commands:
`polars store-ls` - moved from `polars ls`. It provides the list of all
object stored in the plugin cache
`polars store-rm` - deletes a cached object
`polars store-get` - gets an object from the cache. 

The addition of `polars store-get` required adding a reference_count to
cached entries. `polars get` is the only command that will increment
this value. `polars rm` will remove the value despite it's count. Calls
to PolarsPlugin::custom_value_dropped will decrement the value.

The prefix store- was chosen due to there already being a `polars cache`
command. These commands were not made sub-commands as there isn't a way
to display help for sub commands in plugins (e.g. `polars store`
displaying help) and I felt the store- seemed fine anyways.

The output of `polars store-ls` now shows the reference count for each
object.

# User-Facing Changes
polars ls has now moved to polars store-ls

stress_internals: exit(1) on io error (#12612)
# Description

The `stress_internals` tests can fail sometimes, but usually not on the
CI, because Nushell exits while the plugin is still trying to read or
maybe write something, leading to a broken pipe.

`nu-plugin` already exits with 1 without printing a message on a
protocol-level I/O error, so this just doing the same thing.

I think there's probably a way to correct the plugin handling so that we
wait for plugins to shut down before exiting and this doesn't happen,
but this is the quick fix in the meantime.

Overhaul the plugin cache file with a new msgpack+brotli format (#12579)
# Description

- Plugin signatures are now saved to `plugin.msgpackz`, which is
brotli-compressed MessagePack.
- The file is updated incrementally, rather than writing all plugin
commands in the engine every time.
- The file always contains the result of the `Signature` call to the
plugin, even if commands were removed.
- Invalid data for a particular plugin just causes an error to be
reported, but the rest of the plugins can still be parsed

# User-Facing Changes

- The plugin file has a different filename, and it's not a nushell
script.
- The default `plugin.nu` file will be automatically migrated the first
time, but not other plugin config files.
- We don't currently provide any utilities that could help edit this
file, beyond `plugin add` and `plugin rm`
  - `from msgpackz`, `to msgpackz` could also help
- New commands: `plugin add`, `plugin rm`

# Tests + Formatting

Tests added for the format and for the invalid handling.

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

Remove the Value::Block case (#12582)
# Description
`Value` describes the types of first-class values that users and scripts
can create, manipulate, pass around, and store. However, `Block`s are
not first-class values in the language, so this PR removes it from
`Value`. This removes some unnecessary code, and this change should be
invisible to the user except for the change to `scope modules` described
below.

# User-Facing Changes
Breaking change: the output of `scope modules` was changed so that
`env_block` is now `has_env_block` which is a boolean value instead of a
`Block`.

# After Submitting
Update the language guide possibly.

add search_term "str extract" to parse command (#12600)
# Description

For a long time, I was searching for the `str extract` command to
extract regexes from strings. I often painfully used `str replace -r
'(.*)(pattern_to_find)(.*)' '$2'` for such purposes.
Only this morning did I realize that `parse` is what I needed for so
many times, which I had only used for parsing data in tables.

Add version details in `version`'s output. The intended use is for
third-party tools to be able to quickly check version numbers without
having to the parsing from `(version).version` or `$env.NU_VERSION`.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

This adds 4 new values to the record from `version`:

```
...
│ major              │ 0                                               │

```

`pre` is optional and won't be present most of the time I think.

add "to nuon" enumeration of possible styles (#12591)
# Description
in order to change the style of the _serialized_ NUON data,
`nuon::to_nuon` takes three mutually exclusive arguments, `raw: bool`,
`tabs: Option<usize>` and `indent: Option<usize>` 🤔
this begs to use an enumeration with all possible alternatives, right?

this PR changes the signature of `nuon::to_nuon` to use `nuon::ToStyle`
which has three variants
- `Raw`: no newlines
- `Tabs(n: usize)`: newlines and `n` tabulations as indent
- `Spaces(n: usize)`: newlines and `n` spaces as indent

# User-Facing Changes
the signature of `nuon::to_nuon` changes from
```rust
to_nuon(
    input: &Value,
    raw: bool,
    tabs: Option<usize>,
    indent: Option<usize>,
    span: Option<Span>,
) -> Result<String, ShellError>
```
to
```rust
to_nuon(
    input: &Value,
    style: ToStyle,
    span: Option<Span>
) -> Result<String, ShellError>
```

Switch plugin msgpack protocol to named format (#12580)
# Description
In conflict with the documentation, the msgpack serializer for plugins
is actually using the compact format, which doesn't name struct fields,
and is instead dependent on their ordering, rendering them as tuples.
This is not a good idea for a robust protocol even if it makes the
serialization and deserialization faster.

I expect this to have some impact on performance, but I think the
robustness is probably worth it.

Deserialization always accepts either format, so this shouldn't cause
too many incompatibilities.

# User-Facing Changes
This does technically change the protocol, but it makes it reflect the
documentation. It shouldn't break deserialization, so plugins shouldn't
necessarily need a recompile.

Performance is likely worse and I should benchmark the difference.

create nuon crate from from nuon and to nuon (#12553)
# Description
playing with the NUON format in Rust code in some plugins, we agreed
with the team it was a great time to create a standalone NUON format to
allow Rust devs to use this Nushell file format.

> **Note**
> this PR almost copy-pastes the code from
`nu_commands/src/formats/from/nuon.rs` and
`nu_commands/src/formats/to/nuon.rs` to `nuon/src/from.rs` and
`nuon/src/to.rs`, with minor tweaks to make then standalone functions,
e.g. remove the rest of the command implementations

### TODO
- [x] add tests
- [x] add documentation

# User-Facing Changes
devs will have access to a new crate, `nuon`, and two functions,
`from_nuon` and `to_nuon`
```rust
from_nuon(
    input: &str,
    span: Option<Span>,
) -> Result<Value, ShellError>
```
```rust
to_nuon(
    input: &Value,
    raw: bool,
    tabs: Option<usize>,
    indent: Option<usize>,
    span: Option<Span>,
) -> Result<String, ShellError>
```

# Tests + Formatting
i've basically taken all the tests from
`crates/nu-command/tests/format_conversions/nuon.rs` and converted them
to use `from_nuon` and `to_nuon` instead of Nushell commands
- i've created a `nuon_end_to_end` to run both conversions with an
optional middle value to check that all is fine

Add an example Nushell plugin written in Nushell itself (#12574)
# Description

As suggested by @fdncred.

It's neat that this is possible, but the particularly useful part of
this is that we can actually
test it because it doesn't have any external dependencies, unlike the
python plugin.

Right now this just implements exactly the same behavior as the python
plugin, but we could have it
exercise a few more things.

Also fixes a couple of bugs:

- `.nu` plugins were not run with `nu --stdin`, so they couldn't take
input.
- `register` couldn't be called if `--no-config-file` was set, because
it would error on trying to
  update the plugin file.

# User-Facing Changes

- `nu_plugin_nu_example` plugin added.
- `register` now works in `--no-config-file` mode.

# Tests + Formatting
Tests added for `nu_plugin_nu_example`.

- 🟢 `toolkit test stdlib`

Fix circular source causing Nushell to crash (#12262)
# Description

EngineState now tracks the script currently running, instead of the
parent directory of the script. This also provides an easy way to expose
the current running script to the user (Issue #12195).

Similarly, StateWorkingSet now tracks scripts instead of directories.
`parsed_module_files` and `currently_parsed_pwd` are merged into one
variable, `scripts`, which acts like a stack for tracking the current
running script (which is on the top of the stack).

Circular import check is added for `source` operations, in addition to
module import. A simple testcase is added for circular source.

fix(shell_integration): set window title on startup (#12569)
Should close #10833 — though I'd imagine that should have already been
closed.

# Description

Very minor tweak, but it was quite noticeable when using Zellij which
relies on OSC 2 to set pane titles. Before the change:

![image](https://github.com/nushell/nushell/assets/6251883/b944bbce-2040-4886-9955-3c5b57d368e9)

Note that the default `Pane #1` is still showing for the untouched
shell, but running a command like `htop` or `ls` correctly sets the
title during / afterwards.

After this PR:

![image](https://github.com/nushell/nushell/assets/6251883/dd513cfe-923c-450f-b0f2-c66938b0d6f0)

There are now no-longer any unset titles — even if the shell hasn't been
touched.

**As an aside:** I feel quite strongly that (at least OSC 2) shell
integration should be enabled by default, as it is for every other Linux
shell I've used, but I'm not sure which issues that caused that the
default config refers to? Which terminals are broken by shell
integration, and could some of the shell integrations be turned on by
default after splitting things into sub-options as suggested in #11301 ?

# User-Facing Changes

You'll just have shell integrations working from right after the shell
has been launched, instead of needing to run something first.

# Tests + Formatting

Not quite sure how to test this one? Are there any other tests that
currently exist for shell integration? I couldn't quite track them
down...

# After Submitting

Let me know if you think this needs any user-facing docs changes!

You can also set the filepath metadata, although I'm not really user how
useful this is. We may end up removing this option entirely.
```nushell

No file paths are checked. You could also do this.
```nushell
❯ "crates" | metadata set --datasource-filepath $'a/b/c/d/crates' | metadata
╭────────┬────────────────╮
│ source │ a/b/c/d/crates │
╰────────┴────────────────╯
```

The command name and parameter names are still WIP. We could change
them.

There are currently 3 kinds of metadata in nushell.
```rust
pub enum DataSource {
    Ls,
    HtmlThemes,
    FilePath(PathBuf),
}
```

I've skipped adding `HtmlThemes` because it seems to be specific to our
`to html` command only.

Only mark collected dataframes as from_lazy=false when collect is called from the collect command. (#12571)
I had previously changed NuLazyFrame::collect to set the NuDataFrame's
from_lazy field to false to prevent conversion back to a lazy frame. It
appears there are cases where this should happen. Instead, I am only
setting from_lazy=false inside the `polars collect` command.

Box ImportPattern in Expr (#12568)
# Description
Adds a `Box` around the `ImportPattern` in `Expr` which decreases the
size of `Expr` from 152 to 64 bytes (and `Expression` from 216 to 128
bytes). This seems to speed up parsing a little bit according to the
benchmarks (main is top, PR is bottom):

Add ListItem type for Expr::List (#12529)
# Description
This PR adds a `ListItem` enum to our set of AST types. It encodes the
two possible expressions inside of list expression: a singular item or a
spread. This is similar to the existing `RecordItem` enum. Adding
`ListItem` allows us to remove the existing `Expr::Spread` case which
was previously used for list spreads. As a consequence, this guarantees
(via the type system) that spreads can only ever occur inside lists,
records, or as command args.

This PR also does a little bit of cleanup in relevant parser code.

Replace subtraction of Instants and Durations with saturating subtractions (#12549)
# Description
Duration can not be negative, and an underflow causes a panic.

This should fix #12539 as from what I can tell that bug was caused in
`nu-explore:📟:events` from subtracting durations, but I figured
this might be more widespread, and saturating to zero generally makes
sense.

I also added the relevant clippy lint to try to prevent this from
happening in the future. I can't think of a reason we would ever want to
subtract durations without checking first.

Improve safety of get_unchecked_str in nu_system::macos (#12550)
# Description
The implementation of this function had a few issues before:

- It didn't check that the `cp` pointer is actually ahead of the `start`
pointer, so `len` could potentially underflow and wrap around, which
would be a violation of memory safety
- It used `Vec::from_raw_parts` even though the buffer is borrowed, not
owned. Although `std::mem::forget` is used later to ensure the
destructor doesn't run, there is a risk that the destructor would run if
a panic happened during `String::from_utf8_unchecked`, which would lead
to a `free()` of a pointer we don't own

Make group-by return errors in closure (#12508)
# Description
When a closure if provided to `group-by`, errors that occur in the
closure are currently ignored. That is, `group-by` will fall back and
use the `"error"` key if an error occurs. For example, the code snippet
below will group all `ls` entries under the `"error"` column.
```nushell
ls | group-by { get nope } 
```

This PR changes `group-by` to instead bubble up any errors triggered
inside the closure. In addition, this PR also does some refactoring and
cleanup inside `group-by`.

# User-Facing Changes
Errors are now returned from the closure provided to `group-by` instead
of falling back to the `"error"` group/key.

Add a panic unwind handler during plugin calls (#12526)
# Description
If a panic happens during a plugin call, because it always happens
outside of the main thread, it currently just hangs Nushell because the
plugin stays running without ever producing a response to the call.

This adds a panic handler that calls `exit(1)` after the unwind finishes
to the plugin runner. The panic error is still printed to stderr as
always, and waiting for the unwind to finish helps to ensure that
anything on the stack with `Drop` behavior that needed to run still
runs, at least on that thread.

# User-Facing Changes
Panics now look like this, which is what they looked like before the
plugin behavior was moved to a separate thread:

```
thread 'plugin runner (primary)' panicked at crates/nu_plugin_example/src/commands/main.rs:45:9:
Test panic
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Error: nu:🐚:plugin_failed_to_decode

Ensure that lazy frames converted via to-lazy are not converted back to eager frames later in the pipeline. (#12525)
# Description
@maxim-uvarov discovered the following error:
```
> [[a b]; [6 2] [1 4] [4 1]] | polars into-lazy | polars sort-by a | polars unique --subset [a]
Error:   × Error using as series
   ╭─[entry #1:1:68]

   ╰────
 ```
 
During investigation, I discovered the root cause was that the lazy frame was incorrectly converted back to a eager dataframe. In order to keep this from happening, I explicitly set that the dataframe did not come from an eager frame. This causes the conversion logic to not attempt to convert the dataframe later in the pipeline.

Local socket mode and foreground terminal control for plugins (#12448)
# Description

Adds support for running plugins using local socket communication
instead of stdio. This will be an optional thing that not all plugins
have to support.

This frees up stdio for use to make plugins that use stdio to create
terminal UIs, cc @amtoine, @fdncred.

This uses the [`interprocess`](https://crates.io/crates/interprocess)
crate (298 stars, MIT license, actively maintained), which seems to be
the best option for cross-platform local socket support in Rust. On
Windows, a local socket name is provided. On Unixes, it's a path. The
socket name is kept to a relatively small size because some operating
systems have pretty strict limits on the whole path (~100 chars), so on
macOS for example we prefer `/tmp/nu.{pid}.{hash64}.sock` where the hash
includes the plugin filename and timestamp to be unique enough.

This also adds an API for moving plugins in and out of the foreground
group, which is relevant for Unixes where direct terminal control
depends on that.

TODO:

- [x] Generate local socket path according to OS conventions
- [x] Add support for passing `--local-socket` to the plugin executable
instead of `--stdio`, and communicating over that instead
- [x] Test plugins that were broken, including
[amtoine/nu_plugin_explore](https://github.com/amtoine/nu_plugin_explore)
- [x] Automatically upgrade to using local sockets when supported,
falling back if it doesn't work, transparently to the user without any
visible error messages
  - Added protocol feature: `LocalSocket`
- [x] Reset preferred mode to `None` on `register`
- [x] Allow plugins to detect whether they're running on a local socket
and can use stdio freely, so that TUI plugins can just produce an error
message otherwise
  - Implemented via `EngineInterface::is_using_stdio()`
- [x] Clean up foreground state when plugin command exits on the engine
side too, not just whole plugin
- [x] Make sure tests for failure cases work as intended
  - `nu_plugin_stress_internals` added

# User-Facing Changes
- TUI plugins work
- Non-Rust plugins could optionally choose to use this
- This might behave differently, so will need to test it carefully

Improve error messages for plugin protocol by removing #[serde(untagged)] (#12510)
# Description

In the plugin protocol, I had used `#[serde(untagged)]` on the `Stream`
variant to make it smaller and include all of the stream messages at the
top level, but unfortunately this causes serde to make really unhelpful
errors if anything fails to decode anywhere:

```
Error: nu:🐚:plugin_failed_to_decode

  × Plugin failed to decode: data did not match any variant of untagged enum PluginOutput
```

If you are trying to develop something using the plugin protocol
directly, this error is incredibly unhelpful. Even as a user, this
basically just says 'something is wrong'. With this change, the errors
are much better:

```
Error: nu:🐚:plugin_failed_to_decode

  × Plugin failed to decode: unknown variant `PipelineDatra`, expected one of `Error`, `Signature`, `Ordering`, `PipelineData` at line 2 column 37
```

The only downside is it means I have to duplicate all of the
`StreamMessage` variants manually, but there's only 4 of them and
they're small.

This doesn't actually change the protocol at all - everything is still
identical on the wire.

Copy-on-write for record values (#12305)
# Description
This adds a `SharedCow` type as a transparent copy-on-write pointer that
clones to unique on mutate.

As an initial test, the `Record` within `Value::Record` is shared.

There are some pretty big wins for performance. I'll post benchmark
results in a comment. The biggest winner is nested access, as that would
have cloned the records for each cell path follow before and it doesn't
have to anymore.

The reusability of the `SharedCow` type is nice and I think it could be
used to clean up the previous work I did with `Arc` in `EngineState`.
It's meant to be a mostly transparent clone-on-write that just clones on
`.to_mut()` or `.into_owned()` if there are actually multiple
references, but avoids cloning if the reference is unique.

Two consecutive calls to into-lazy should not fail (#12505)
# Description

From @maxim-uvarov's

When calling `to-lazy` back to back in a pipeline, an error should not
occur:

```
> [[a b]; [6 2] [1 4] [4 1]] | polars into-lazy | polars into-lazy
Error: nu:🐚:cant_convert

  × Can't convert to NuDataFrame.

This pull request ensures that custom value's of NuLazyFrameCustomValue are properly converted when passed in.

Refactor first and last (#12478)
# Description

- Refactors `first` and `last` using `Vec::truncate` and `Vec::drain`.
- `std::mem::take` was also used to eliminate a few `Value` clones.
- The `NeedsPositiveValue` error now uses the span of the `rows`
argument instead of the call head span.
- `last` now errors on an empty stream to match `first` which does
error.
-  Made metadata preservation more consistent.

Ensure that two columns named index don't exist when converting a Dataframe to a nu Value. (#12501)
# Description
@maxim-uvarov discovered an issue with the current implementation. When
executing [[index a]; [1 1]] | polars into-df, a plugin_failed_to_decode
error occurs. This happens because a Record is created with two columns
named "index" as an index column is added during conversion. This pull
request addresses the problem by not adding an index column if there is
already a column named "index" in the dataframe.

Handle relative paths correctly on polars to-(parquet|jsonl|arrow|etc) commands (#12486)
# Description

All polars commands that output a file were not handling relative paths
correctly.

A command like
``` [[a b]; [6 2] [1 4] [4 1]] | polars into-df | polars to-parquet foo.json``` 
was outputting the foo.json to the directory of the plugin executable. 

This pull request pulls in nu-path and using it for resolving the file paths.

fix std log (#12470)
related to
- https://github.com/nushell/nushell/pull/12196

# Description
while i'm 100% okey with the original intent behind
https://github.com/nushell/nushell/pull/12196, i think the PR did
introduce two unintended things:
- extra parentheses that make the `log.nu` module look like Lisp lol
- a renaming of the `NU_LOG_LEVEL` environment variable to
`NU_log-level`. this breaks previous usage of `std log` and, as it's not
mentionned at all in the PR, i thought it was not intentional 😋

# User-Facing Changes
users can now control `std log` with `$env.NU_LOG_LEVEL`

# Tests + Formatting
the "log" tests have been fixed as well.

Isolate tests from user config (#12437)
# Description
This is an attempt to isolate the unit tests from whatever might be in
the user's config. If the
user's config is broken in some way or incompatible with this version
(for example, especially if
there are plugins that aren't built for this version), tests can
spuriously fail.

This makes tests more reliably pass the same way they would on CI even
if the user has config, and
should also make them run faster.

I think this is _good enough_, but I still think we should have a
specific config dir env variable for nushell specifically (rather than
having to use `XDG_CONFIG_HOME`, which would mess with other things) and
then we can just have `nu-test-support` set that to a temporary dir
containing the shipped default config files.

Rename IoStream to OutDest (#12433)
# Description
I spent a while trying to come up with a good name for what is currently
`IoStream`. Looking back, this name is not the best, because it:
1. Implies that it is a stream, when it all it really does is specify
the output destination for a stream/pipeline.
2. Implies that it handles input and output, when it really only handles
output.

So, this PR renames `IoStream` to `OutDest` instead, which should be
more clear.

Add --no-newline option to nu (#12410)
# Description
I have `nu` set as my shell in my editor, which allows me to easily pipe
selections of text to things like `str pascal-case` or even more complex
string operation pipelines, which I find super handy. However, the only
annoying thing is that I pretty much always have to add `| print -n` at
the end, because `nu` adds a newline when it prints the resulting value.

This adds a `--no-newline` option to stop that from happening, and then
you don't need to pipe to `print -n` anymore, you can just have your
shell command for your editor contain that flag.

Add GetSpanContents engine call (#12439)
# Description
This allows plugins to view the source code of spans.

Requested by @ayax79 for implementing `polars ls`. Note that this won't
really help you find the location of the span. I'm planning to add
another engine call that will return information more similar to what
shows up in the miette diagnostics, with filename / line number / some
context, but I'll want to refactor some of the existing logic to make
that happen, so it was easier to just do this first. I hope this is
enough to at least have something somewhat useful show up for `polars
ls`.

Use nu-cmd-lang default context for plugin tests (#12434)
# Description
@ayax79 added `nu-cmd-lang` as a dep for `nu-plugin-test-support` in
order to get access to `let`. Since we have the dep anyway now, we might
as well just add all of the lang commands - there aren't very many of
them and it would be less confusing than only `let` working.

# User-Facing Changes
- Can use some more core nu language features in plugin tests, like
loops and `do`

- 🟢 `toolkit clippy`
- 🟢 `toolkit test`

# After Submitting

Implement De-/Serialize for Record manually (#12365)
# Description
This decouples the serialized representation of `Record` from its
internal implementation. It now gets treated as a map type in `serde`.

This has several benefits:
- more efficient representation (not showing inner fields)
- human readable e.g. as a JSON record
- no breaking changes when refactoring the `Record` internals in the
future (see #12326, or potential introduction of `indexmap::IndexMap`
for large N)
- we now deny the creation of invalid records a non-cooperating plugin
could produce
  - guaranteed key-value correspondence
  - checking for unique keys

# Breaking change to the plugin protocol:
Now expects a record/map directly as the `Record.val` field instead of a
serialization of it.

Fix nushell#10591: encode returns error with utf-16le and utf-16be encodings (nushell#10591) (#12411)
# Description

This closes (nushell#10591)

The Command encode's help text says that utf-16le and utf-16be encodings
are not supported, however you could still use these encodings and they
didn't work properly, since they returned the bytes UTF-8 encoded:

time guarantees.

specifically the permissions checking and users.

Add BufWriter to ChildStdin on the plugin interface (#12419)
# Description
This speeds up writing messages to the plugin, because otherwise every
individual piece of the messages (not even the entire message) is
written with one syscall, leading to a lot of back and forth with the
kernel.

I learned this by running `strace` to debug something and saw a ton of
`write()` calls.

# Before
1..10 | each { timeit { example seq 1 10000 | example sum } } | math avg

Improve handling of custom values in plugin examples (#12409)
# Description
Requested by @ayax79. This makes the custom value behavior more correct,
by calling the methods on the plugin to handle the custom values in
examples rather than the methods on the custom values themselves. This
helps for handle-type custom values (like what he's doing with
dataframes).

- Equality checking in `PluginTest::test_examples()` changed to use
`PluginInterface::custom_value_partial_cmp()`
- Base value rendering for `PluginSignature` changed to use
`Plugin::custom_value_to_base_value()`
- Had to be moved closer to `serve_plugin` for this reason, so the test
for writing signatures containing custom values was removed
- That behavior should still be tested to some degree, since if custom
values are not handled, signatures will fail to parse, so all of the
other tests won't work.

# User-Facing Changes

- `Record::sort_cols()` method added to share functionality required by
`PartialCmp`, and it might also be slightly faster
- Otherwise, everything should mostly be the same but better. Plugins
that don't implement special handling for custom values will still work
the same way, because the default implementation is just a pass-through
to the `CustomValue` methods.

Fix deadlock on PluginCustomValue drop (#12418)
# Description
Because the plugin interface reader thread can be responsible for
sending a drop notification, it's possible for it to end up in a
deadlock where it's waiting for the response to the drop notification
call.

I decided that the best way to address this is to just discard the
response and not wait for it. It's not really important to synchronize
with the response to `Dropped`, so this is probably faster anyway.

cc @ayax79, this is your issue where polars is getting stuck

# User-Facing Changes
- A bug fix

Looking at the condition, `TRASH_SUPPORTED && (trash || (rm_always_trash

enabled and `--permanent` is disabled.

This suggests that the `--trash` suggestion is a mistake and should have

Fix #12391: mkdir uses process startup directory instead of current script directory (#12394)
# Description

This fixes #12391.

nushell/nushell@87c5f6e455 accidentally introduced a bug where the path
was not being properly
expanded according to the cwd. This makes both 'touch' and 'mkdir' use
globs just like the rest of
the commands to preserve tilde behavior while still expanding the paths
properly.

This doesn't actually expand the globs. Should it?

# User-Facing Changes

- Restore behavior of `mkdir`, `touch`
- Help text now says they can take globs, but they won't actually expand
them, maybe this should be changed

# Tests + Formatting

Regression tests added.


# After Submitting

This is severe enough and should be included in the point release.

Fix hooks on 0.92.0 (#12383)
# Description
Fixes #12382, where overlay changes from hooks were not preserved into
the global state. This was due to creating child stacks for hooks, when
the global stack should have been used instead.

Make drop notification timing for plugin custom values more consistent (#12341)
# Description
This keeps plugin custom values that have requested drop notification
around during the lifetime of a plugin call / stream by sending them to
a channel that gets persisted during the lifetime of the call.

Before this change, it was very likely that the drop notification would
be sent before the plugin ever had a chance to handle the value it
received.

Tests have been added to make sure this works - see the `custom_values`
plugin.

# User-Facing Changes
This is basically just a bugfix, just a slightly big one.

However, I did add an `as_mut_any()` function for custom values, to
avoid having to clone them. This is a breaking change.

Make default config conservative about clipboard (#12385)
Some platforms don't support the `system-clipboard` feature, notably
termux on android.
The default config currently contained references to `reedline` events
that are only available with the feature enabled (#12179). This thus
broke the out of the box config for those users.

For now be more defensive about this and only enable default events. Add
the alternative as commented out code you can quickly enable.

## Tested with:

```
cargo run --no-default-features --features default-no-clipboard -- --config crates/nu-utils/src/sample_config/default_config.nu

mkdir umask fix (#12354)
# Description
Fixes how the directory permissions are calculated in `mkdir`. Instead
of subtraction, the umask is actually used as a mask via negation
followed by bitwise and with the default mode. This matches how [uucore
calculates](cac7155fba/src/uu/mkdir/src/mkdir.rs (L61))
the mode.

Refactor Record to use a single backing Vec (#12326)
# Description
This shrinks `Record`'s size in half and and allows you to include it in
`Value` without growing the size.

Changing the `Record` internals may have slightly different performance
characteristics as the cache locality changes on lookups (if you
directly need the value, it should be closer, but in other cases may
blow up the cache line budget)

Also different perf characteristics on creation expected. 
`Record::from_raw_cols_vals` now probably worse.

## Benchmarking

Comparison with the main branch (boxed Record) revealed no significant
change to the creation but an improvement when accessing larger N.
The fact that this was more pronounced for nested access (still cloning
before nushell/nushell#12325) leads to the conclusion that this may
still be dominated by the smaller clone necessary for a 24-byte `Record`
over the previous 48 bytes.

Remove ambiguous into bits impl for date (#12313)
# Description
Currently `into bits` will try to coerce a `date`/`Value::Date` into a
string with a locale/timezone specific behavior (See #12268).

To resolve the ambiguity, remove the support for `date` entirely.


# User-Facing Changes
`date now | into bits` will now fail.

Instead you can use `... | format date '%c' | into bits` or any more
specific explicit choices to achieve the same behavior.

As `into bits` has minimal uses (and only pulled out of `extra` with
#12140), this doesn't warrant a deprecation.

Remove serde derive for ShellError, replace via LabeledError (#12319)
# Description

This changes the interface for plugins to always represent errors as
`LabeledError`s. This is good for altlang plugins, as it would suck for
them to have to implement and track `ShellError`. We save a lot of
generated code from the `ShellError` serde impl too, so `nu` and plugins
get to have a smaller binary size.

Reduces the release binary size by 1.2 MiB on my build configuration.

# User-Facing Changes

- Changes plugin protocol. `ShellError` no longer serialized.
- `ShellError` serialize output is different
- `ShellError` no longer deserializes to exactly the same value as
serialized

Elide clone in V::follow_cell_path for record (#12325)
# Description
This clone is not necessary and tanks the performance of deep nested
access.
As soon as we found the value, we know we discard the old value, so can
`std::mem::take` the inner (`impl Default for Value` to the rescue)

We may be able to further optimize this but not having to clone the
value is vital.

into sqlite: Fix insertion of null values (#12328)
# Description

In #10232, the allowed input types were changed to be stricter, only
allowing records with types that can easily map onto sqlite equivalents.
Unfortunately, null was left out of the accepted input types, which
makes inserting rows with null values impossible.

This change fixes that by accepting null values as input.

One caveat of this is that when the command is creating a new table, it
uses the first row to infer an appropriate sqlite schema. If the first
row contains a null value, then it is impossible to tell which type this
column is supposed to have.

Throwing a hard error seems undesirable from a UX perspective, but
guessing can lead to a potentially useless database if we guess wrong.

So as a compromise, for null columns, we will assume the sqlite type is
TEXT and print a warning so the user knows. For the time being, if users
can't avoid a first row with null values, but also wants the right
schema, they are advised to create their table before running `into
sqlite`.

A future PR can add the ability to explicitly specify a schema.

Fixes #12225

* Tests added to cover expected behavior around insertion of null values

The second `Value` is redundant and will consume five extra bytes on

# User-Facing Changes
This is a breaking change to the plugin protocol.

    "val": {
      "type": "PluginCustomValue",
      "name": "database",
      "data": [36, 190, 127, 40, 12, 3, 46, 83],
      "notify_on_drop": true
    },
    "span": {
      "start": 320,
      "end": 340

- updating `wl-clipboard-rs` to `0.8.1`
- update our own dependency on `nix` from `0.27` to `0.28`
  - required fixing uses of `nix::unistd::{tcgetpgrp,tcsetpgrp}`
  - now requires an I/O safe file descriptor
  - fake one pointing to `libc::STDIN_FILENO` (we were only accessing

Change PluginCommand API to be more like Command (#12279)
# Description

This is something that was discussed in the core team meeting last
Wednesday. @ayax79 is building `nu-plugin-polars` with all of the
dataframe commands into a plugin, and there are a lot of them, so it
would help to make the API more similar. At the same time, I think the
`Command` API is just better anyway. I don't think the difference is
justified, and the types for core commands have the benefit of requiring
less `.into()` because they often don't own their data

- Broke `signature()` up into `name()`, `usage()`, `extra_usage()`,
`search_terms()`, `examples()`
- `signature()` returns `nu_protocol::Signature`
- `examples()` returns `Vec<nu_protocol::Example>`
- `PluginSignature` and `PluginExample` no longer need to be used by
plugin developers

Add command_prelude module (#12291)
# Description
When implementing a `Command`, one must also import all the types
present in the function signatures for `Command`. This makes it so that
we often import the same set of types in each command implementation
file. E.g., something like this:
```rust
use nu_protocol::ast::Call;
use nu_protocol::engine::{Command, EngineState, Stack};
use nu_protocol::{
    record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, PipelineData,
    ShellError, Signature, Span, Type, Value,
};
```

This PR adds the `nu_engine::command_prelude` module which contains the
necessary and commonly used types to implement a `Command`:
```rust
// command_prelude.rs
pub use crate::CallExt;
pub use nu_protocol::{
    ast::{Call, CellPath},
    engine::{Command, EngineState, Stack},
    record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, IntoSpanned,
    PipelineData, Record, ShellError, Signature, Span, Spanned, SyntaxShape, Type, Value,
};
```

This should reduce the boilerplate needed to implement a command and
also gives us a place to track the breadth of the `Command` API. I tried
to be conservative with what went into the prelude modules, since it
might be hard/annoying to remove items from the prelude in the future.
Let me know if something should be included or excluded.

Always pretty print binary values in table (#12294)
# Description
Binary values passed to `table` may or may not be pretty formatted based
on the output destination. This leads to weird behavior as documented in
#12287. This PR changes `table` to always pretty print binary values.
However, binary values passed to external commands will not be formatted
(this is the existing behavior).

# User-Facing Changes
This is a breaking change. E.g.:
```nushell
0x[8989] | table | cat -
```
used to print raw bytes, but it will now print the pretty formatted
bytes.

# After Submitting
Add to 0.92.0 release notes and update documentation.

Fix return in filter closure eval (#12292)
# Description
Closes https://github.com/nushell/nushell/issues/12257

This was down to the use of `eval_block` instead of
`eval_block_with_early_return`. We may want to reconsider how we
differentiate between this behavior. We currently need to check all the
remaining commands that can invoke a closure block, if they properly
handle `ShellError::Return` as a passing of a `Value`

- **Add test for `return` in `filter` closure**
- **Fix use of `return` in `filter` closure**

# User-Facing Changes
You can now return a value from a `filter` closure

Change default algorithm in detect columns (#12277)
# Description
@fdncred found another histogram based algorithm to detect columns, and
rewrite it in rust: https://github.com/fdncred/guess-width

I have tested it manually, and it works good with `df`, `docker ps`,
`^ps`. This pr is going to use the algorithm in `detect columns`

Fix: #4183

The pitfall of new algorithm:
1. it may not works well if there isn't too much rows of input
2. it may not works well if the length of value is less than the header
to value, e.g:
```
c1 c2 c3 c4 c5
a b c d e
g h i j k
g a a q d
a v c q q | detect columns
```
In this case, users might need to use ~~`--old`~~ `--legacy` to make it
works well.

# User-Facing Changes
User might need to add ~~`--old`~~ `--legacy` to scripts if they find
`detect columns` in their scripts broken.

Fix #12280: replace difference crate with similar (#12282)
Fixes #12280.

# Description

This removes the dependency on the `difference` crate, which is
unmaintained, for `nu-plugin-test-support`. The `similar` crate
(Apache-2.0) is used instead, which is a bit larger and more complex,
but still suitable for a dev dep for tests. Also switched to use
`crossterm` for colors, since `similar` doesn't come with any terminal
pretty printing functionality.

# User-Facing Changes

None - output should be identical.

Initial implementation for uutils uname (#11684)
Hi,
This PR aims at implementing the first iteration for `uname` using
`uutils`. Couple of things:
* Currently my [PR](https://github.com/uutils/coreutils/pull/5921) to
make the required changes is pending in `uutils` repo.
* I guess the number of flags has to be investigated. Still the tests
cover all of them.

ls, rm, cp, open, touch, mkdir: Don't expand tilde if input path is quoted string or a variable. (#12232)
# Description
Fixes:  #11887
Fixes: #11626

This pr unify the tilde expand behavior over several filesystem relative
commands. It follows the same rule with glob expansion:
|  command  |  result |
| ----------- |  ------ |
| ls ~/aaa  | expand tilde
| ls "~/aaa"  | don't expand tilde
| let f = "~/aaa"; ls $f | don't expand tilde, if you want to: use `ls
($f \| path expand)`
| let f: glob = "~/aaa"; ls $f | expand tilde, they don't expand on
`mkdir`, `touch` comamnd.

Actually I'm not sure for 4th item, currently it's expanding is just
because it followes the same rule with glob expansion.

### About the change
It changes `expand_path_with` to accept a new argument called
`expand_tilde`, if it's true, expand it, if not, just keep it as `~`
itself.

# User-Facing Changes
After this change, `ls "~/aaa"` won't expand tilde.

# Tests + Formatting
Done

Initial --params implementation (#12249)
# Description
This PR adds a `--params` param to `query db`. This closes #11643.

You can't combine both named and positional parameters, I think this
might be a limitation with rusqlite itself. I tried using named
parameters with indices like `{ ':named': 123, '1': "positional" }` but
that always failed with a rusqlite error. On the flip side, the other
way around works: for something like `VALUES (:named, ?)`, you can treat
both as positional: `-p [hello 123]`.

This PR introduces some very gnarly code repetition in
`prepared_statement_to_nu_list`. I tried, I swear; the compiler wasn't
having any of it, it kept telling me to box my closures and then it said
that the reference lifetimes were incompatible in the match arms. I gave
up and put the mapping code in the match itself, but I'm still not
happy.

Another thing I'm unhappy about: I don't like how you have to put the
`:colon` in named parameters. I think nushell should insert it if it's
[missing](https://www.sqlite.org/lang_expr.html#parameters). But this is
the way [rusqlite
works](https://docs.rs/rusqlite/latest/rusqlite/trait.Params.html#example-named),
so for now, I'll let it be consistent. Just know that it's not really a
blocker, and it isn't a compatibility change to later make `{ colon: 123
}` work, without the quotes and `:`. This would require allocating and
turning our pretty little `&str` into a `String`, though

# User-Facing Changes
Less incentive to leave yourself open to SQL injection with statements
like `query db $"INSERT INTO x VALUES \($unsafe_user_input)"`.
Additionally, the `$""` syntax being annoying with parentheses plays in
our favor, making users even more likely to use ? with `--params`.

🐛 remove 3 backticks messing the hover (#12273)
# Description

The hover was bugged with 3 backticks. I don't understand how it worked
before, but this apparently now works correctly on my machine. This is
really puzzling. My next step is to make a test to assert this will
break a little less. I fixed it 3 times in the past

Added a test to be sure this doesn't breaks again 😄 (at least from

Make some of the stream tests more robust against bad timeouts (#12271)
# Description

@WindSoilder [reported on

that some plugin stream tests have been failing on the CI. It seems to
just be a timing thing (probably due to busy CI), so this extends the
amount of time that we can wait for a condition to be true.

Support for getting help text from a plugin command (#12243)
# Description
There wasn't really a good way to implement a command group style (e.g.
`from`, `query`, etc.) command in the past that just returns the help
text even if `--help` is not passed. This adds a new engine call that
just does that.

This is actually something I ran into before when developing the dbus
plugin, so it's nice to fix it.

Add test support crate for plugin developers (#12259)
# Description

Adds a `nu-plugin-test-support` crate with an interface that supports
testing plugins.

Unlike in reality, these plugins run in the same process on separate
threads. This will allow
testing aspects of the plugin internal state and handling serialized
plugin custom values easily.
We still serialize their custom values and all of the engine to plugin
logic is still in play, so
from a logical perspective this should still expose any bugs that would
have been caused by that.
The only difference is that it doesn't run in a different process, and
doesn't try to serialize
everything to the final wire format for stdin/stdout.

TODO still:

- [x] Clean up warnings about private types exposed in trait definition
- [x] Automatically deserialize plugin custom values in the result so
they can be inspected
- [x] Automatic plugin examples test function
- [x] Write a bit more documentation
- [x] More tests
- [x] Add MIT License file to new crate

# User-Facing Changes

Plugin developers get a nice way to test their plugins.

# Tests + Formatting
Run the tests with `cargo test -p nu-plugin-test-support --
--show-output` to see some examples of what the failing test output for
examples can look like. I used the `difference` crate (MIT licensed) to
make it look nice.

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

# After Submitting

- [ ] Add a section to the book about testing
- [ ] Test some of the example plugins this way
- [ ] Add example tests to nu_plugin_template so plugin developers have
something to start with

nu-explore/ Use hex-dump for binary data (#12184)
Hi there

So as 2 minute thing we could show `hex-dump` as it is as a string
(no-coloring).

But I'd do some more things around,.
Probably will take a few days (WIP).

Bump base64 from 0.21.7 to 0.22.0 (#12188)

<blockquote>
<h1>0.22.0</h1>
<ul>
<li><code>DecodeSliceError::OutputSliceTooSmall</code> is now
conservative rather than precise. That is, the error will only occur if
the decoded output <em>cannot</em> fit, meaning that
<code>Engine::decode_slice</code> can now be used with exactly-sized
output slices. As part of this, <code>Engine::internal_decode</code> now
returns <code>DecodeSliceError</code> instead of
<code>DecodeError</code>, but that is not expected to affect any
external callers.</li>
<li><code>DecodeError::InvalidLength</code> now refers specifically to
the <em>number of valid symbols</em> being invalid (i.e. <code>len % 4
== 1</code>), rather than just the number of input bytes. This avoids
confusing scenarios when based on interpretation you could make a case
for either <code>InvalidLength</code> or <code>InvalidByte</code> being
appropriate.</li>
<li>Decoding is somewhat faster (5-10%)</li>

changes.

Description of your pull request goes here. **Provide examples and/or

-->
When the `command_not_found` hook is entered, we set an environment
variable for context. If an unknown command is encountered and the
`command_not_found` context environment variable is already present, it
implies a command in the hook closure is also not found. We stop the
recursion right there.

Fix: missing parse error when extra tokens are given to let bindings (#12238)
Manual checks are added to `parse_let`, `parse_mut`, and `parse_const`.
`parse_var_with_opt_type` is also fixed to update `spans_idx` correctly.
Fixes #12125.

It's technically a fix, but I'd rather not merge this directly. I'm
making this PR to bring into attention the code quality of the parser
code. For example:

* Inconsistent usage of `spans_idx`. What is its purpose, and which
parsing functions need it? I suspect it's possible to remove the usage
of `spans_idx` entirely.
* Lacking documentation for top-level functions. What does `mutable`
mean for `parse_var_with_opt_type()`?
* Inconsistent error reporting. Usage of both `working_set.error()` and
`working_set.parse_errors.push()`. Using `ParseError::Expected` for an
invalid variable name when there's `ParseError::VariableNotValid` (from
`parser.rs:5237`). Checking variable names manually when there's
`is_variable()` (from `parser.rs:2905`).
* `span()` is a terrible name for a function that flattens a bunch of
spans into one (from `nu-protocal/src/span.rs:92`). The top-level
comment (`Used when you have a slice of spans of at least size 1`)
doesn't help either.

I've only looked at a small portion of the parser code; I expect there
are a lot more. These issues made it much harder to fix a simple bug
like #12125. I believe we should invest some effort to cleanup the
parser code, which will ease maintainance in the future. I'll willing to
help if there is interest.

Better generic errors for plugins (and perhaps scripts) (#12236)
# Description
This makes `LabeledError` much more capable of representing close to
everything a `miette::Diagnostic` can, including `ShellError`, and
allows plugins to generate multiple error spans, codes, help, etc.

`LabeledError` is now embeddable within `ShellError` as a transparent
variant.

This could also be used to improve `error make` and `try/catch` to
reflect `LabeledError` exactly in the future.

Also cleaned up some errors in existing plugins.

Refactor source cache into CachedFile struct (#12240)

This also makes the representation more compact as no capacity is

Fix usage of --tabs flag while converting to json (#12115) (#12251)
closes #12115 

# Description
This fix addresses a bug where the --tabs flag couldn't be utilized due
to improper handling of the tab quantity provided by the user.
Previously, the code mistakenly attempted to convert the tab quantity to
a boolean value, leading to a conversion error. The resolution involves
adjusting the condition clauses to properly validate the presence of the
flag's value. Now, the code checks whether the get_flag() function
returns a value or None associated with the --tabs flag. This adjustment
enables the --tabs flag to function correctly, triggering the
appropriate condition and allowing the conversion to proceed as
expected. Similarly, the fix applies to the --indent flag. Additionally,
a default case was added, and the conversion now works properly without
flags. Two tests were added to validate the corrected behavior of these
flags.

# User-Facing Changes
Now the conversion should work properly instead of displaying an error.

Make EngineState clone cheaper with Arc on all of the heavy objects (#12229)
# Description
This makes many of the larger objects in `EngineState` into `Arc`, and
uses `Arc::make_mut` to do clone-on-write if the reference is not
unique. This is generally very cheap, giving us the best of both worlds
- allowing us to mutate without cloning if we have an exclusive
reference, and cloning if we don't.

This started as more of a curiosity for me after remembering that
`Arc::make_mut` exists and can make using `Arc` for mostly immutable
data that sometimes needs to be changed very convenient, and also after
hearing someone complain about memory usage on Discord - this is a
somewhat significant win for that.

The exact objects that were wrapped in `Arc`:

- `files`, `file_contents` - the strings and byte buffers
- `decls` - the whole `Vec`, but mostly to avoid lots of individual
`malloc()` calls on Clone rather than for memory usage
- `blocks` - the blocks themselves, rather than the outer Vec
- `modules` - the modules themselves, rather than the outer Vec
- `env_vars`, `previous_env_vars` - the entire maps
- `config`

The changes required were relatively minimal, but this is a breaking API
change. In particular, blocks are added as Arcs, to allow the parser
cache functionality to work.

With my normal nu config, running on Linux, this saves me about 15 MiB
of process memory usage when running interactively (65 MiB → 50 MiB).

This also makes quick command executions cheaper, particularly since
every REPL loop now involves a clone of the engine state so that we can
recover from a panic. It also reduces memory usage where engine state
needs to be cloned and sent to another thread or kept within an
iterator.

# User-Facing Changes
Shouldn't be any, since it's all internal stuff, but it does change some
public interfaces so it's a breaking change

Make custom value type handling more consistent (#12230)
[Context on
Discord](https://discord.com/channels/601130461678272522/855947301380947968/1219425984990806207)

# Description

- Rename `CustomValue::value_string()` to `type_name()` to reflect its
usage better.
- Change print behavior to always call `to_base_value()` first, to give
the custom value better control over the output.
- Change `describe --detailed` to show the type name as the subtype,
rather than trying to describe the base value.
- Change custom `Type` to use `type_name()` rather than `typetag_name()`
to make things like `PluginCustomValue` more transparent

One question: should `describe --detailed` still include a description
of the base value somewhere? I'm torn on it, it seems possibly useful
for some things (maybe sqlite databases?), but having `describe -d` not
include the custom type name anywhere felt weird. Another option would
be to add another method to `CustomValue` for info to be displayed in
`describe`, so that it can be more type-specific?

Support for custom values in plugin examples (#12213)
# Description
@ayax79 says that the dataframe commands all have dataframe custom
values in their examples, and they're used for tests.

Rather than send the custom values to the engine, if they're in
examples, this change just renders them using `to_base_value()` first.
That way we avoid potentially having to hold onto custom values in
`plugins.nu` that might not be valid indefinitely - as will be the case
for dataframes in particular - but we still avoid forcing plugin writers
to not use custom values in their examples.

With the introduction of the system clipboard to nushell, many commands
changed their behavior from using a local cut buffer to the system
clipboard, perhaps surprisingly for many users. (See #11907)
This PR changes most of them back to using the local cut buffer and
introduces three commands (`CutSelectionSystem`, `CopySelectionSystem`
and `PasteSystem`) to explicitly use the system clipboard.


# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

Users who in the meantime already used the system clipboard now default

Allow plugins to set environment variables in their caller's scope (#12204)
# Description

Adds the `AddEnvVar` plugin call, which allows plugins to set
environment variables in the caller's scope. This is the first engine
call that mutates the caller's stack, and opens the door to more
operations like this if needed.

This also comes with an extra benefit: in doing this, I needed to
refactor how context was handled, and I was able to avoid cloning
`EngineInterface` / `Stack` / `Call` in most cases that plugin calls are
used. They now only need to be cloned if the plugin call returns a
stream. The performance increase is welcome (5.5x faster on `inc`!):

```nushell

I referred to the implementation of `mkdir` in uutils/coreutils. I add

be any additional dependencies.

Reorganize plugin API around commands (#12170)
[Context on
Discord](https://discord.com/channels/601130461678272522/855947301380947968/1216517833312309419)

# Description
This is a significant breaking change to the plugin API, but one I think
is worthwhile. @ayax79 mentioned on Discord that while trying to start
on a dataframes plugin, he was a little disappointed that more wasn't
provided in terms of code organization for commands, particularly since
there are *a lot* of `dfr` commands.

This change treats plugins more like miniatures of the engine, with
dispatch of the command name being handled inherently, each command
being its own type, and each having their own signature within the trait
impl for the command type rather than having to find a way to centralize
it all into one `Vec`.

For the example plugins that have multiple commands, I definitely like
how this looks a lot better. This encourages doing code organization the
right way and feels very good.

For the plugins that have only one command, it's just a little bit more
boilerplate - but still worth it, in my opinion.

The `Box<dyn PluginCommand<Plugin = Self>>` type in `commands()` is a
little bit hairy, particularly for Rust beginners, but ultimately not so
bad, and it gives the desired flexibility for shared state for a whole
plugin + the individual commands.

# User-Facing Changes
Pretty big breaking change to plugin API, but probably one that's worth
making.

```rust
use nu_plugin::*;
use nu_protocol::{PluginSignature, PipelineData, Type, Value};

struct LowercasePlugin;
struct Lowercase;

// Plugins can now have multiple commands
impl PluginCommand for Lowercase {
    type Plugin = LowercasePlugin;

    // The signature lives with the command
    fn signature(&self) -> PluginSignature {
        PluginSignature::build("lowercase")
            .usage("Convert each string in a stream to lowercase")
            .input_output_type(Type::List(Type::String.into()), Type::List(Type::String.into()))
    }

    // We also provide SimplePluginCommand which operates on Value like before
    fn run(
        &self,
        plugin: &LowercasePlugin,
        engine: &EngineInterface,
        call: &EvaluatedCall,
        input: PipelineData,
    ) -> Result<PipelineData, LabeledError> {
        let span = call.head;
        Ok(input.map(move |value| {
            value.as_str()
                .map(|string| Value::string(string.to_lowercase(), span))
                // Errors in a stream should be returned as values.
                .unwrap_or_else(|err| Value::error(err, span))
        }, None)?)
    }
}

// Plugin now just has a list of commands, and the custom value op stuff still goes here
impl Plugin for LowercasePlugin {
    fn commands(&self) -> Vec<Box<dyn PluginCommand<Plugin=Self>>> {
        vec![Box::new(Lowercase)]
    }
}

fn main() {
    serve_plugin(&LowercasePlugin{}, MsgPackSerializer)
}
```

Time this however you like - we're already breaking stuff for 0.92, so
it might be good to do it now, but if it feels like a lot all at once,
it could wait.

IO and redirection overhaul (#11934)
# Description
The PR overhauls how IO redirection is handled, allowing more explicit
and fine-grain control over `stdout` and `stderr` output as well as more
efficient IO and piping.

To summarize the changes in this PR:
- Added a new `IoStream` type to indicate the intended destination for a
pipeline element's `stdout` and `stderr`.
- The `stdout` and `stderr` `IoStream`s are stored in the `Stack` and to
avoid adding 6 additional arguments to every eval function and
`Command::run`. The `stdout` and `stderr` streams can be temporarily
overwritten through functions on `Stack` and these functions will return
a guard that restores the original `stdout` and `stderr` when dropped.
- In the AST, redirections are now directly part of a `PipelineElement`
as a `Option<Redirection>` field instead of having multiple different
`PipelineElement` enum variants for each kind of redirection. This
required changes to the parser, mainly in `lite_parser.rs`.
- `Command`s can also set a `IoStream` override/redirection which will
apply to the previous command in the pipeline. This is used, for
example, in `ignore` to allow the previous external command to have its
stdout redirected to `Stdio::null()` at spawn time. In contrast, the
current implementation has to create an os pipe and manually consume the
output on nushell's side. File and pipe redirections (`o>`, `e>`, `e>|`,
etc.) have precedence over overrides from commands.

This PR improves piping and IO speed, partially addressing #10763. Using
the `throughput` command from that issue, this PR gives the following
speedup on my setup for the commands below:
| Command | Before (MB/s) | After (MB/s) | Bash (MB/s) |
| --------------------------- | -------------:| ------------:|
-----------:|
| `throughput o> /dev/null` | 1169 | 52938 | 54305 |
| `throughput \| ignore` | 840 | 55438 | N/A |
| `throughput \| null` | Error | 53617 | N/A |
| `throughput \| rg 'x'` | 1165 | 3049 | 3736 |
| `(throughput) \| rg 'x'` | 810 | 3085 | 3815 |

(Numbers above are the median samples for throughput)

This PR also paves the way to refactor our `ExternalStream` handling in
the various commands. For example, this PR already fixes the following
code:
```nushell
^sh -c 'echo -n "hello "; sleep 0; echo "world"' | find "hello world"
```
This returns an empty list on 0.90.1 and returns a highlighted "hello
world" on this PR.

Since the `stdout` and `stderr` `IoStream`s are available to commands
when they are run, then this unlocks the potential for more convenient
behavior. E.g., the `find` command can disable its ansi highlighting if
it detects that the output `IoStream` is not the terminal. Knowing the
output streams will also allow background job output to be redirected
more easily and efficiently.

# User-Facing Changes
- External commands returned from closures will be collected (in most
cases):
  ```nushell
  1..2 | each {|_| nu -c "print a" }
  ```
This gives `["a", "a"]` on this PR, whereas this used to print "a\na\n"
and then return an empty list.

  ```nushell
  1..2 | each {|_| nu -c "print -e a" }
  ```
This gives `["", ""]` and prints "a\na\n" to stderr, whereas this used
to return an empty list and print "a\na\n" to stderr.

- Trailing new lines are always trimmed for external commands when
piping into internal commands or collecting it as a value. (Failure to
decode the output as utf-8 will keep the trailing newline for the last
binary value.) In the current nushell version, the following three code
snippets differ only in parenthesis placement, but they all also have
different outputs:

  1. `1..2 | each { ^echo a }`
     ```
     a
     a
     ╭────────────╮
     │ empty list │
     ╰────────────╯
     ```
  2. `1..2 | each { (^echo a) }`
     ```
     ╭───┬───╮
     │ 0 │ a │
     │ 1 │ a │
     ╰───┴───╯
     ```
  3. `1..2 | (each { ^echo a })`
     ```
     ╭───┬───╮
     │ 0 │ a │
     │   │   │
     │ 1 │ a │
     │   │   │
     ╰───┴───╯
     ```

  But in this PR, the above snippets will all have the same output:
  ```
  ╭───┬───╮
  │ 0 │ a │
  │ 1 │ a │
  ╰───┴───╯
  ```

- All existing flags on `run-external` are now deprecated.

- File redirections now apply to all commands inside a code block:
  ```nushell
  (nu -c "print -e a"; nu -c "print -e b") e> test.out
  ```
This gives "a\nb\n" in `test.out` and prints nothing. The same result
would happen when printing to stdout and using a `o>` file redirection.

- External command output will (almost) never be ignored, and ignoring
output must be explicit now:
  ```nushell
  (^echo a; ^echo b)
  ```
This prints "a\nb\n", whereas this used to print only "b\n". This only
applies to external commands; values and internal commands not in return
position will not print anything (e.g., `(echo a; echo b)` still only
prints "b").

- `complete` now always captures stderr (`do` is not necessary).

Disable fmt feature of polars(-core) (#12151)
In normal operations we don't display the dataframes directly.
The `fmt` feature on `polars-core` pulls in the `comfy-table` crate with
its own dependencies on `crossterm` and `strum(_macros)`.
This has the chance to duplicate dependencies. (currently strum version
divergence)

Without this feature only the shapes should be displayed.

May degrade the error output during testing.

MsgPack deserializer: improve handling of EOF (#12183)
# Description

`rmp_serde` has two kinds of errors that contain I/O errors, and an EOF
can occur inside either of them, but we were only treating an EOF inside
an `InvalidMarkerRead` as an EOF, which would make sense for the
beginning of a message.

However, we should also treat an incomplete message + EOF as an EOF.
There isn't really any point in reporting that an EOF was received
mid-message.

This should fix the issue where the
`seq_describe_no_collect_succeeds_without_error` test would sometimes
fail, as doing a `describe --no-collect` followed by nushell exiting
could (but was not guaranteed to) cause this exact scenario.

# User-Facing Changes
Will probably remove useless `read error` messages from plugins after
exit of `nu`

Because `std::fs::canonicalize` requires the path to exist, this PR
makes it so that when canonicalizing any config file, the
`$nu.default-config-dir/nushell` part is canonicalized first, then
`$nu.default-config-dir/nushell/foo.nu` is canonicalized.

This should also fix the issue @devyn pointed out
[here](https://github.com/nushell/nushell/pull/12118#issuecomment-1989546708)
where a couple of the tests failed if one's `~/.config/nushell` folder
was actually a symlink to a different folder. The tests previously
didn't canonicalize the expected paths.

I was going to make a PR that caches the config directory on startup (as
suggested by fdncred and Ian in Discord), but I can make that part of
this PR if we want to avoid creating unnecessary PRs. I think it
probably makes more sense to separate them though.

Fix locking soundness in PersistentPlugin (#12182)
# Description

There were two problems in `PersistentPlugin` which could cause a
deadlock:

1. There were two mutexes being used, and `get()` could potentially hold
both simultaneously if it had to spawn. This won't necessarily cause a
deadlock on its own, but it does mean that lock order is sensitive

2. `set_gc_config()` called `flush()` while still holding the lock,
meaning that the GC thread had to proceed before the lock was released.
However, waiting for the GC thread to proceed could mean waiting for the
GC thread to call `stop()`, which itself would try to lock the mutex.
So, it's not safe to wait for the GC thread while the lock is held. This
is fixed now.

I've also reverted #12177, as @IanManske reported that this was also
happening for him on Linux, and it seems to be this problem which should
not be platform-specific at all. I believe this solves it.

Add environment engine calls for plugins (#12166)
# Description

This adds three engine calls: `GetEnvVar`, `GetEnvVars`, for getting
environment variables from the plugin command context, and
`GetCurrentDir` for getting the current working directory.

Plugins are now launched in the directory of their executable to try to
make improper use of the current directory without first setting it more
obvious. Plugins previously launched in whatever the current directory
of the engine was at the time the plugin command was run, but switching
to persistent plugins broke this, because they stay in whatever
directory they launched in initially.

This also fixes the `gstat` plugin to use `get_current_dir()` to
determine its repo location, which was directly affected by this
problem.

# User-Facing Changes
- Adds new engine calls (`GetEnvVar`, `GetEnvVars`, `GetCurrentDir`)
- Runs plugins in a different directory from before, in order to catch
bugs
- Plugins will have to use the new engine calls if they do filesystem
stuff to work properly

# After Submitting

Sync with the plugin garbage collector when setting config (#12152)
# Description
This causes `PersistentPlugin` to wait for the plugin garbage collector
to actually receive and process its config when setting it in
`set_gc_config`.

The motivation behind doing this is to make setting GC config in scripts
more deterministic. Before this change we couldn't really guarantee that
the GC could see your config before you started doing other things.

There is a slight cost to performance to doing this - we set config
before each plugin call because we don't necessarily know that it
reflects what's in `$env.config`, and now to do that we have to
synchronize with the GC thread.

This was probably the cause of spuriously failing tests as mentioned by
@sholderbach. Hopefully this fixes it. It might be the case that
launching threads on some platforms (or just on a really busy test
runner) sometimes takes a significant amount of time.

# User-Facing Changes
- possibly slightly worse performance for plugin calls

Support for all custom value operations on plugin custom values (#12088)
# Description

Adds support for the following operations on plugin custom values, in
addition to `to_base_value` which was already present:

- `follow_path_int()`
- `follow_path_string()`
- `partial_cmp()`
- `operation()`
- `Drop` (notification, if opted into with
`CustomValue::notify_plugin_on_drop`)

There are additionally customizable methods within the `Plugin` and
`StreamingPlugin` traits for implementing these functions in a way that
requires access to the plugin state, as a registered handle model such
as might be used in a dataframes plugin would.

`Value::append` was also changed to handle custom values correctly.

# User-Facing Changes

- Signature of `CustomValue::follow_path_string` and
`CustomValue::follow_path_int` changed to give access to the span of the
custom value itself, useful for some errors.
- Plugins using custom values have to be recompiled because the engine
will try to do custom value operations that aren't supported
- Plugins can do more things 🎉 

# Tests + Formatting

Closes #12103

# Description

As described in #12103, this PR makes Nushell use `XDG_CONFIG_HOME` as
the config directory if it exists. Otherwise, it uses the old behavior,
which was to use `dirs_next::config_dir()`.

Edit: We discussed choosing between `XDG_CONFIG_HOME` and the default
config directory in Discord and decided against it, at least for now.

<s>@kubouch also suggested letting users choose between
`XDG_CONFIG_HOME` and the default config directory if config files
aren't found on startup and `XDG_CONFIG_HOME` is set to a value
different from the default config directory</s>

On Windows and MacOS, if the `XDG_CONFIG_HOME` variable is set but
`XDG_CONFIG_HOME` is either empty or doesn't exist *and* the old config
directory is non-empty, Nushell will issue a warning on startup saying
that it won't move files from the old config directory to the new one.
To do this, I had to add a `nu_path::config_dir_old()` function. I
assume that at some point, we will remove the warning message and the
function can be removed too. Alternatively, instead of having that
function there, `main.rs` could directly call `dirs_next::config_dir()`.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

When `$env.XDG_CONFIG_HOME` is set to an absolute path, Nushell will use
`$"($env.XDG_CONFIG_HOME)/nushell"` as its config directory (previously,
this only worked on Linux).

To use `App Data\Roaming` (Windows) or `Library/Application Support`
(MacOS) instead (the old behavior), one can either leave
`XDG_CONFIG_HOME` unset or set it to an empty string.

If `XDG_CONFIG_HOME` is set, but to a non-absolute/invalid path, Nushell
will report an error on startup and use the default config directory
instead:

`~/.config`, so the documentation could warn about that mistake.

do command: Make closure support default parameters and type checking (#12056)
# Description
Fixes: #11287
Fixes: #11318

It's implemented by porting the similar logic in `eval_call`, I've tried
to reduce duplicate code, but it seems that it's hard without using
macros.

3ee2fc60f9/crates/nu-engine/src/eval.rs (L60-L130)

It only works for `do` command.

# User-Facing Changes
## Closure supports optional parameter
```nushell
let code = {|x?| print ($x | default "i'm the default")}
do $code
```
Previously it raises an error, after this change, it prints `i'm the
default`.

## Closure supports type checking
```nushell
let code = {|x: int| echo $x}
do $code "aa"
```
After this change, it will raise an error with a message: `can't convert
string to int`

Restructure nu-protocol in more meaningful units (#11917)
This is partially "feng-shui programming" of moving things to new
separate places.

The later commits include "`git blame` tollbooths" by moving out chunks
of code into new files, which requires an extra step to track things
with `git blame`. We can negiotiate if you want to keep particular
things in their original place.

If egregious I tried to add a bit of documentation. If I see something
that is unused/unnecessarily `pub` I will try to remove that.


- Move `nu_protocol::Exportable` to `nu-parser`
- Guess doccomment for `Exportable`
- Move `Unit` enum from `value` to `AST`
- Move engine state `Variable` def into its folder
- Move error-related files in `nu-protocol` subdir
- Move `pipeline_data` module into its own folder
- Move `stream.rs` over into the `pipeline_data` mod
- Move `PipelineMetadata` into its own file
- Doccomment `PipelineMetadata`
- Remove unused `is_leap_year` in `value/mod`
- Note about criminal `type_compatible` helper
- Move duration fmting into new `value/duration.rs`
- Move filesize fmting logic to new `value/filesize`
- Split reexports from standard imports in `value/mod`

Remove feat extra and include in default (#12140)
# Description
The intended effect of the `extra` feature has been undermined by
introducing the full builds on our release pages and having more
activity on some of the extra commands.

To simplify the feature matrix let's get rid of it and focus our effort
on truly either refining a command to well-specified behavior or
discarding it entirely from the `nu` binary and moving it into plugins.

## Details
- Remove `--features extra` from CI
- Don't explicitly name `extra` in full build wf
- Remove feature extra from build-help scripts
- Update README in `nu-cmd-extra`
- Remove feature `extra`
- Fix previously dead `format pattern` tests
- Relax signature of `to html`
- Fix/ignore `html::test_no_color_flag`
- Remove dead features from `version`
- Refine `to html` type signature

# User-Facing Changes
The commands that were previously only available when building with
`--features extra` will now be available to everyone. This increases the
number of dependencies slightly but has a limited impact on the overall
binary size.

# Tests + Formatting
Some tests that were left in `nu-command` during cratification were dead
because the feature was not passed to `nu-command` and only to
`nu-cmd-lang` for feature-flag mention in `version`.
Those tests have now been either fixed or ignored in one case.

# After Submitting
There may be places in the documentation where we point to `--features
extra` that will now be moot (apart from the generated command help)

Canonicalize config dir (#12136)
It turns out that my previous PR,
https://github.com/nushell/nushell/pull/11999, didn't properly
canonicalize `$nu.default-config-dir` in a scenario where
`XDG_CONFIG_HOME` (or the equivalent on each platform) was a symlink. To
remedy that, this PR makes `nu_path::config_dir()` return a
canonicalized path. This probably shouldn't break anything (except maybe
tests relying on the old behavior), since the canonical path will be
equivalent to non-canonical paths.

# User-Facing Changes

A user may get a path with symlinks resolved and `..`s replaced where
they previously didn't. I'm not sure where this would happen, though,
and anyway, the canonical path is probably the "correct" thing to
present to the user. We're using `omnipath` to make the path presentable
to the user on Windows, so there's no danger of someone getting an path
with `\\?` there.

# Tests + Formatting

The tests for config files have been updated to run the binary using the
`Director` so that it has access to the `XDG_CONFIG_HOME`/`HOME`
environment variables to be able to change the config directory.

Keep plugins persistently running in the background (#12064)
# Description
This PR uses the new plugin protocol to intelligently keep plugin
processes running in the background for further plugin calls.

Running plugins can be seen by running the new `plugin list` command,
and stopped by running the new `plugin stop` command.

This is an enhancement for the performance of plugins, as starting new
plugin processes has overhead, especially for plugins in languages that
take a significant amount of time on startup. It also enables plugins
that have persistent state between commands, making the migration of
features like dataframes and `stor` to plugins possible.

Plugins are automatically stopped by the new plugin garbage collector,
configurable with `$env.config.plugin_gc`:

```nushell
  $env.config.plugin_gc = {
      # Configuration for plugin garbage collection
      default: {
          enabled: true # true to enable stopping of inactive plugins
          stop_after: 10sec # how long to wait after a plugin is inactive to stop it
      }
      plugins: {
          # alternate configuration for specific plugins, by name, for example:
          #
          # gstat: {
          #     enabled: false
          # }
      }
  }
```

If garbage collection is enabled, plugins will be stopped after
`stop_after` passes after they were last active. Plugins are counted as
inactive if they have no running plugin calls. Reading the stream from
the response of a plugin call is still considered to be activity, but if
a plugin holds on to a stream but the call ends without an active
streaming response, it is not counted as active even if it is reading
it. Plugins can explicitly disable the GC as appropriate with
`engine.set_gc_disabled(true)`.

The `version` command now lists plugin names rather than plugin
commands. The list of plugin commands is accessible via `plugin list`.

Recommend doing this together with #12029, because it will likely force
plugin developers to do the right thing with mutability and lead to less
unexpected behavior when running plugins nested / in parallel.

# User-Facing Changes
- new command: `plugin list`
- new command: `plugin stop`
- changed command: `version` (now lists plugin names, rather than
commands)
- new config: `$env.config.plugin_gc`
- Plugins will keep running and be reused, at least for the configured
GC period
- Plugins that used mutable state in weird ways like `inc` did might
misbehave until fixed
- Plugins can disable GC if they need to
- Had to change plugin signature to accept `&EngineInterface` so that
the GC disable feature works. #12029 does this anyway, and I'm expecting
(resolvable) conflicts with that

# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

Because there is some specific OS behavior required for plugins to not
respond to Ctrl-C directly, I've developed against and tested on both
Linux and Windows to ensure that works properly.

I think this probably needs to be in the book somewhere

Add support for engine calls from plugins (#12029)
# Description

This allows plugins to make calls back to the engine to get config,
evaluate closures, and do other things that must be done within the
engine process.

Engine calls can both produce and consume streams as necessary. Closures
passed to plugins can both accept stream input and produce stream output
sent back to the plugin.

Engine calls referring to a plugin call's context can be processed as
long either the response hasn't been received, or the response created
streams that haven't ended yet.

This is a breaking API change for plugins. There are some pretty major
changes to the interface that plugins must implement, including:

1. Plugins now run with `&self` and must be `Sync`. Executing multiple
plugin calls in parallel is supported, and there's a chance that a
closure passed to a plugin could invoke the same plugin. Supporting
state across plugin invocations is left up to the plugin author to do in
whichever way they feel best, but the plugin object itself is still
shared. Even though the engine doesn't run multiple plugin calls through
the same process yet, I still considered it important to break the API
in this way at this stage. We might want to consider an optional
threadpool feature for performance.

2. Plugins take a reference to `EngineInterface`, which can be cloned.
This interface allows plugins to make calls back to the engine,
including for getting config and running closures.

3. Plugins no longer take the `config` parameter. This can be accessed
from the interface via the `.get_plugin_config()` engine call.


# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
Not only does this have plugin protocol changes, it will require plugins
to make some code changes before they will work again. But on the plus
side, the engine call feature is extensible, and we can add more things
to it as needed.

Plugin maintainers will have to change the trait signature at the very
least. If they were using `config`, they will have to call
`engine.get_plugin_config()` instead.

If they were using the mutable reference to the plugin, they will have
to come up with some strategy to work around it (for example, for `Inc`
I just cloned it). This shouldn't be such a big deal at the moment as
it's not like plugins have ever run as daemons with persistent state in
the past, and they don't in this PR either. But I thought it was
important to make the change before we support plugins as daemons, as an
exclusive mutable reference is not compatible with parallel plugin
calls.

I suggest this gets merged sometime *after* the current pending release,
so that we have some time to adjust to the previous plugin protocol
changes that don't require code changes before making ones that do.

# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`

# After Submitting
I will document the additional protocol features (`EngineCall`,
`EngineCallResponse`), and constraints on plugin call processing if
engine calls are used - basically, to be aware that an engine call could
result in a nested plugin call, so the plugin should be able to handle
that.

This PR refactors `nu-check` and makes it possible to check module
directories. Also removes the requirement for files to end with .nu: It
was too limiting for module directories and there are executable scripts
[around](https://github.com/nushell/nu_scripts/tree/main/make_release/release-note)
that do not end with .nu, it's a common practice for scripts to omit it.

Other changes are:
* Removed the `--all` flag and heuristic parse because these are
irrelevant now when module syntax is a subset of script syntax (i.e.,
every module can be parsed as script).
* Reduced code duplication and in general tidied up the code
* Replaced unspanned errors with spanned ones.

Allow for stacks to have parents (#11654)
This is another attempt on #11288 

This allows for a `Stack` to have a parent stack (behind an `Arc`). This
is being added to avoid constant stack copying in REPL code.

Concretely the following changes are included here:
- `Stack` can now have a `parent_stack`, pointing to another stack
- variable lookups can fallback to this parent stack (env vars and
everything else is still copied)
- REPL code has been reworked so that we use parenting rather than
cloning. A REPL-code-specific trait helps to ensure that we do not
accidentally trigger a full clone of the main stack
- A property test has been added to make sure that parenting "looks the
same" as cloning for consumers of `Stack` objects
