# Description
This PR adds a new method to `EngineInterface`: `register_ctrlc_handler`
which takes a closure to run when the plugin's driving engine receives a
ctrlc-signal. It also adds a mirror of the `signals` attribute from the
main shell `EngineState`.
This is an example of how a plugin which makes a long poll http request
can end the request on ctrlc:
https://github.com/cablehead/nu_plugin_http/blob/main/src/commands/request.rs#L68-L77
To facilitate the feature, a new attribute has been added to
`EngineState`: `ctrlc_handlers`. This is a Vec of closures that will be
run when the engine's process receives a ctrlc signal.
When plugins are added to an `engine_state` during a `merge_delta`, the
engine passes the ctrlc_handlers to the plugin's
`.configure_ctrlc_handler` method, which gives the plugin a chance to
register a handler that sends a ctrlc packet through the
`PluginInterface`, if an instance of the plugin is currently running.
On the plugin side: `EngineInterface` also has a ctrlc_handlers Vec of
closures. Plugin calls can use `register_ctrlc_handler` to register a
closure that will be called in the plugin process when the
PluginInput::Ctrlc command is received.
For future reference these are some alternate places that were
investigated for tying the ctrlc trigger to transmitting a Ctrlc packet
through the `PluginInterface`:
- Directly from `src/signals.rs`: the handler there would need a
reference to the Vec<Arc<RegisteredPlugins>>, which would require us to
wrap the plugins in a Mutex, which we don't want to do.
- have `PersistentPlugin.get_plugin` pass down the engine's
CtrlcHandlers to .get and then to .spawn (if the plugin isn't already
running). Once we have CtrlcHandlers in spawn, we can register a handler
to write directly to PluginInterface. We don't want to double down on
passing engine_state to spawn this way though, as it's unpredictable
because it would depend on whether the plugin has already been spawned
or not.
- pass `ctrlc_handlers` to PersistentPlugin::new so it can store it on
itself so it's available to spawn.
- in `PersistentPlugin.spawn`, create a handler that sends to a clone of
the GC event loop's tx. this has the same issues with regards to how to
get CtrlcHandlers to the spawn method, and is more complicated than a
handler that writes directly to PluginInterface

# Description
Seems like I developed a bit of a bad habit of trying to link
```rust
/// [`.foo()`]
```
in docstrings, and this just doesn't work automatically; you have to do
```rust
/// [`.foo()`](Self::foo)
```
if you want it to actually link. I think I found and replaced all of
these.
# User-Facing Changes
Just docs.
# Description
Just realized I hadn't been cleaning up the arguments added to the
`Stack` after the `CallDecl` engine call was finished, so there could be
a bit of a memory leak if a plugin made many calls during the duration
of a single plugin call. This is a quick patch to that.
I'm probably going to revise how this all works at some point soon
because I think it is a bit of a pitfall. It would be good to make it
much more difficult to make a mistake with it, perhaps with a guard like
Ian did for the redirection stuff.
# After Submitting
- [ ] release with 0.96.1
# Description
[Discovered](https://discord.com/channels/601130461678272522/614593951969574961/1266503282554179604)
by `@warp` on Discord.
The IR compiler was not properly setting redirect modes for
subexpressions because `FullCellPath` was always being compiled with
capture-out redirection. This is the correct behavior if there is a tail
to the `FullCellPath`, as we need the value in order to try to extract
anything from it (although this is unlikely to work) - however, the
parser also generates `FullCellPath`s with an empty tail quite often,
including for bare subexpressions.
Because of this, the following did not behave as expected:
```nushell
(docker run -it --rm alpine)
```
Capturing the output meant that `docker` didn't have direct access to
the terminal as a TTY.
As this is a minor bug fix, it should be okay to include in the 0.96.1
patch release.
# User-Facing Changes
- Fixes the bug as described when running with IR evaluation enabled.
# Tests + Formatting
I added a test for this, though we're not currently running all tests
with IR on the CI, but it should ensure this behaviour is consistent.
The equivalent minimum repro I could find was:
```nushell
(nu --testbin cococo); null
```
as this should cause the `cococo` message to appear on stdout, and if
Nushell is capturing the output, it would be discarded instead.
# Description

# Description
This corrects the parsing of unknown arguments provided to known
externals to behave exactly like external arguments passed to normal
external calls.
I've done this by adding a `SyntaxShape::ExternalArgument` which
triggers the same parsing rules.
Because I didn't like how the highlighting looked, I modified the
flattener to emit `ExternalArg` flat shapes for arguments that have that
syntax shape and are plain strings/globs. This is the same behavior that
external calls have.
Aside from passing the tests, I've also checked manually that the
completer seems to work adequately. I can confirm that specified
positional arguments get completion according to their specified type
(including custom completions), and then anything remaining gets
filepath style completion, as you'd expect from an external command.
Thanks to @OJarrisonn for originally finding this issue.
# User-Facing Changes
- Unknown args are now parsed according to their specified syntax shape,
rather than `Any`. This may be a breaking change, though I think it's
extremely unlikely in practice.
- The unspecified arguments of known externals are now highlighted /
flattened identically to normal external arguments, which makes it more
clear how they're being interpreted, and should help the completer
function properly.
- Known externals now have an implicit rest arg if not specified named
`args`, with a syntax shape of `ExternalArgument`.

Adds a `--quiet` flag to the `watch` command, silencing the message
usually shown when invoking `watch`.
Resolves#13411
As implemented, `--quiet` is orthogonal to `--verbose`. I'm open to
improving the flag's name, behaviour and/or documentation to make it
more user-friendly, as I realise this may be surprising as-is.
```

# Description
Trying to help @amtoine out here - the spans calculated by `ast::Call`
by `span()` and `argument_span()` are suspicious and are not properly
guarding against `end` that might be before `start`. Just using
`Span::merge()` / `merge_many()` instead to try to make the behaviour as
simple and consistent as possible. Hopefully then even if the arguments
have some crazy spans, we don't have spans that are just totally
invalid.

# User-Facing Changes
It's a breaking change because we have switched the position of
`<initial>` and `<closure>`, after the change, initial value will be
optional. So it's possible to do something like this:
```nushell
> let f = {|fib = [0, 1]| {out: $fib.0, next: [$fib.1, ($fib.0 + $fib.1)]} }
> generate $f | first 5
╭───┬───╮
│ 0 │ 0 │
│ 1 │ 1 │
│ 2 │ 1 │
│ 3 │ 2 │
│ 4 │ 3 │
╰───┴───╯
```
It will also raise error if user don't give initial value, and the
closure don't have default parameter.
```nushell
❯ let f = {|fib| {out: $fib.0, next: [$fib.1, ($fib.0 + $fib.1)]} }
❯ generate $f
Error: × The initial value is missing

# Description
Adds functionality to the plugin interface to support calling internal
commands from plugins. For example, using `view ir --json`:
```rust
let closure: Value = call.req(0)?;
let Some(decl_id) = engine.find_decl("view ir")? else {
return Err(LabeledError::new("`view ir` not found"));
};
let ir_json = engine.call_decl(
decl_id,
EvaluatedCall::new(call.head)
.with_named("json".into_spanned(call.head), Value::bool(true, call.head))
.with_positional(closure),
PipelineData::Empty,
true,
false,
)?.into_value()?.into_string()?;
let ir = serde_json::from_value(&ir_json);
// ...
```
# User-Facing Changes
Plugin developers can now use `EngineInterface::find_decl()` and
`call_decl()` to call internal commands, which could be handy for
formatters like `to csv` or `to nuon`, or for reflection commands that
help gain insight into the engine.

# Description
Following from #13377, this PR refactors the related `window` command.
In the case where `window` should behave exactly like `chunks`, it now
reuses the same code that `chunks` does. Otherwise, the other cases have
been rewritten and have resulted in a performance increase:
| window size | stride | old time (ms) | new time (ms) |
| -----------:| ------:| -------------:| -------------:|
| 20 | 1 | 757 | 722 |
| 2 | 1 | 364 | 333 |
| 1 | 1 | 343 | 293 |
| 20 | 20 | 90 | 63 |
| 2 | 2 | 215 | 175 |
| 20 | 30 | 74 | 60 |
| 2 | 4 | 141 | 110 |
# User-Facing Changes
`window` will now error if the window size or stride is 0, which is
technically a breaking change.

# Description
This grew quite a bit beyond its original scope, but I've tried to make
`$in` a bit more consistent and easier to work with.
Instead of the parser generating calls to `collect` and creating
closures, this adds `Expr::Collect` which just evaluates in the same
scope and doesn't require any closure.
When `$in` is detected in an expression, it is replaced with a new
variable (also called `$in`) and wrapped in `Expr::Collect`. During
eval, this expression is evaluated directly, with the input and with
that new variable set to the collected value.
Other than being faster and less prone to gotchas, it also makes it
possible to typecheck the output of an expression containing `$in`,
which is nice. This is a breaking change though, because of the lack of
the closure and because now typechecking will actually happen. Also, I
haven't attempted to typecheck the input yet.
The IR generated now just looks like this:
```gas
collect %in
clone %tmp, %in
store-variable $in, %tmp
# %out <- ...expression... <- %in
drop-variable $in
```
(where `$in` is the local variable created for this collection, and not
`IN_VARIABLE_ID`)
which is a lot better than having to create a closure and call `collect
--keep-env`, dealing with all of the capture gathering and allocation
that entails. Ideally we can also detect whether that input is actually
needed, so maybe we don't have to clone, but I haven't tried to do that
yet. Theoretically now that the variable is a unique one every time, it
should be possible to give it a type - I just don't know how to
determine that yet.
On top of that, I've also reworked how `$in` works in pipeline-initial
position. Previously, it was a little bit inconsistent. For example,
this worked:
```nushell
> 3 | do { let x = $in; let y = $in; print $x $y }
3
3
```
However, this causes a runtime variable not found error on the second
`$in`:
```nushell
> def foo [] { let x = $in; let y = $in; print $x $y }; 3 | foo
Error: nu:🐚:variable_not_found
× Variable not found
╭─[entry #115:1:35]
1 │ def foo [] { let x = $in; let y = $in; print $x $y }; 3 | foo
· ─┬─
· ╰── variable not found
╰────
```
I've fixed this by making the first element `$in` detection *always*
happen at the block level, so if you use `$in` in pipeline-initial
position anywhere in a block, it will collect with an implicit
subexpression around the whole thing, and you can then use that `$in`
more than once. In doing this I also rewrote `parse_pipeline()` and
hopefully it's a bit more straightforward and possibly more efficient
too now.
Finally, I've tried to make `let` and `mut` a lot more straightforward
with how they handle the rest of the pipeline, and using a redirection
with `let`/`mut` now does what you'd expect if you assume that they
consume the whole pipeline - the redirection is just processed as
normal. These both work now:
```nushell
let x = ^foo err> err.txt
let y = ^foo out+err>| str length
```
It was previously possible to accomplish this with a subexpression, but
it just seemed like a weird gotcha that you couldn't do it. Intuitively,
`let` and `mut` just seem to take the whole line.
- closes#13137
# User-Facing Changes
- `$in` will behave more consistently with blocks and closures, since
the entire block is now just wrapped to handle it if it appears in the
first pipeline element
- `$in` no longer creates a closure, so what can be done within an
expression containing `$in` is less restrictive
- `$in` containing expressions are now type checked, rather than just
resulting in `any`. However, `$in` itself is still `any`, so this isn't
quite perfect yet
- Redirections are now allowed in `let` and `mut` and behave pretty much
how you'd expect

Replaces the `dirs_next` family of crates with `dirs`. `dirs_next` was
born when the `dirs` crates were abandoned three years ago, but they're
being maintained again and most projects depend on `dirs` nowadays.
`dirs_next` has been abandoned since.
This came up while working on
https://github.com/nushell/nushell/pull/13382.

# Description
Before this change `default` would dive into lists and replace `null`
elements with the default value.
Therefore there was no easy way to process `null|list<null|string>`
input and receive `list<null|string>`
(IOW to apply the default on the top level only).
However it's trivially easy to apply default values to list elements
with the `each` command:
```nushell
[null, "a", null] | each { default "b" }
```
So there's no need to have this behavior in `default` command.
# User-Facing Changes
* `default` no longer dives into lists to replace `null` elements with
the default value.
# Tests + Formatting
Added a couple of tests for the new (and old) behavior.
# After Submitting
* Update docs.
# Description
The name of the `group` command is a little unclear/ambiguous.
Everything I look at it, I think of `group-by`. I think `chunks` more
clearly conveys what the `group` command does. Namely, it divides the
input list into chunks of a certain size. For example,
[`slice::chunks`](https://doc.rust-lang.org/std/primitive.slice.html#method.chunks)
has the same name. So, this PR adds a new `chunks` command to replace
the now deprecated `group` command.
The `chunks` command is a refactored version of `group`. As such, there
is a small performance improvement:
```nushell
# $data is a very large list
> bench { $data | chunks 2 } --rounds 30 | get mean
474ms 921µs 190ns
# deprecation warning was disabled here for fairness
> bench { $data | group 2 } --rounds 30 | get mean
592ms 702µs 440ns
> bench { $data | chunks 200 } --rounds 30 | get mean
374ms 188µs 318ns
> bench { $data | group 200 } --rounds 30 | get mean
481ms 264µs 869ns
> bench { $data | chunks 1 } --rounds 30 | get mean
642ms 574µs 42ns
> bench { $data | group 1 } --rounds 30 | get mean
981ms 602µs 513ns
```
# User-Facing Changes
- `group` command has been deprecated in favor of new `chunks` command.
- `chunks` errors when given a chunk size of `0` whereas `group` returns
chunks with one element.
# Tests + Formatting
Added tests for `chunks`, since `group` did not have any tests.
# After Submitting
Update book if necessary.
# Description
This is a minor breaking change to JSON output syntax/style of the `to
json` command.
This fixes#13326 by setting `braces_same_line` to true when creating a
new `HjsonFormatter`.
This then simply tells `HjsonFormatter` to keep the braces on the same
line when outputting which is what I expected nu's `to json` command to
do.
There are almost no changes to nushell itself, all changes are contained
within `nu-json` crate (minus any documentation updates).
Oh, almost forgot to mention, to get the tests compiling, I added
fancy_regex as a _dev_ dependency to nu-json. I could look into
eliminating that if desirable.
# User-Facing Changes
**Breaking Change**
nushell now outputs the desired result using the reproduction command
from the issue:
```
echo '{"version": "v0.4.4","notes": "blablabla","pub_date": "2024-05-04T16:05:00Z","platforms":{"windows-x86_64":{"signature": "blablabla","url": "https://blablabla"}}}' | from json | to json
```
outputs:
```
{
"version": "v0.4.4",
"notes": "blablabla",
"pub_date": "2024-05-04T16:05:00Z",
"platforms": {
"windows-x86_64": {
"signature": "blablabla",
"url": "https://blablabla"
}
}
}
```
whereas previously it would push the opening braces onto a new line:
```
{
"version": "v0.4.4",
"notes": "blablabla",
"pub_date": "2024-05-04T16:05:00Z",
"platforms":
{
"windows-x86_64":
{

}
}
```
# Tests + Formatting
toolkit check pr mostly passes - there are regrettably some tests not
passing on my windows machine _before making any changes_ (I may look
into this as a separate issue)
I have re-enabled the [hjson
tests](https://github.com/nushell/nushell/blob/main/crates/nu-json/tests/main.rs).
This is done in the second commit 🙂
They have a crucial difference to what they were previously asserting:
* nu-json outputs in json syntax, not hjson syntax
I think this is desirable, but I'm not aware of the history of these
tests.
# After Submitting
I suspect there `to json` command examples will need updating to match,
haven't checked yet!
# Description
Report parse warnings and compile errors when running script files.
It's useful to report this information to script authors and users so
they can know if they need to update something in the near future.
I also found that moving some errors from eval to compile time meant
some error tests can fail (in `tests/repl`) so this is a good idea to
keep those passing.
# User-Facing Changes
- Report parse warnings when running script files
- Report compile errors when running script files
# Description
Add `README.md` files to each crate in our workspace (-plugins) and also
include it in the `lib.rs` documentation for <docs.rs> (if there is no
existing `lib.rs` crate documentation)
In all new README I added the defensive comment that the crates are not
considered stable for public consumption. If necessary we can adjust
this if we deem a crate useful for plugin authors.
# Description
Fixes#13359
In an attempt to generate names for flat columns resulting from a nested
accesses #3016 generated new column names on nested selection, out of
convenience, that composed the cell path as a string (including `.`) and
then simply replaced all `.` with `_`. As we permit `.` in column names
as long as you quote this surprisingly alters `select`ed columns.
# User-Facing Changes
New columns generated by selection with nested cell paths will for now
be named with a string containing the keys separated by `.` instead of
`_`. We may want to reconsider the semantics for nested access.
# Tests + Formatting

Touch was added to the shell command context twice, once with the other

# Description
This adds tracing for each individual instruction to the `Debugger`
trait. Register contents can be inspected both when entering and leaving
an instruction, and if an instruction produced an error, a reference to
the error is also available. It's not the full `EvalContext` but it's
most of the important parts for getting an idea of what's going on.
Added support for all of this to the `Profiler` / `debug profile` as
well, and the output is quite incredible - super verbose, but you can
see every instruction that's executed and also what the result was if
it's an instruction that has a clearly defined output (many do).
# User-Facing Changes
- Added `--instructions` to `debug profile`, which adds the `pc` and
`instruction` columns to the output.
- `--expr` only works in AST mode, and `--instructions` only works in IR
mode. In the wrong mode, the output for those columns is just blank.

# Description
This improves the error when the determined output of a custom command
doesn't match the specified output type by adding the actual determined
output type.
# User-Facing Changes
Previous: `command doesn't output {0}`
New: `expected {0}, but command outputs {1}`
# Tests + Formatting
Passing.
# After Submitting
- [ ] release notes? (minor change, but helpful)
# Description
Just a quick one, but `List(Any)` has to come before `Table`, because
`List(Any)` is a valid match for `Table`, so it will choose `Table`
output even if the input was actually `List(Any)`. I ended up removing
`Table` because it's just not needed at all anyway.
Though, I'm not really totally sure this is correct - I think the parser
should probably actually just have some idea of what the more specific
type is, and choose the most specific type match, rather than just doing
it in order. I guess this will result in the output just always being
`List(Any)` for now. Still better than a bad typecheck error
# User-Facing Changes
Fixes the following contrived example:
```nushell
def foo []: nothing -> list<int> {
seq 1 10 | # list<int>
each { |n| $n * 20 } | # this causes the type to become list<any>
take until { |x| $x < 10 } } # table is first, so now this is type table
# ...but table is not compatible with list<int>
}
```
# After Submitting
- [ ] make typechecker type choice more robust
- [ ] release notes
Somehow this logic was missed on my end. ( I mean I was not even
thinking about it in original patch 😄 )
Please recheck
Added a regression test too.

# Description
Follow up fix to #13332, so that changes to config when running under IR
actually happen as well. Since I merged them around the same time, I
forgot about this.
# Description
Allows `Stack` to have a modified local `Config`, which is updated
immediately when `$env.config` is assigned to. This means that even
within a script, commands that come after `$env.config` changes will
always see those changes in `Stack::get_config()`.
Also fixed a lot of cases where `engine_state.get_config()` was used
even when `Stack` was available.
Closes#13324.
# User-Facing Changes
- Config changes apply immediately after the assignment is executed,
rather than whenever config is read by a command that needs it.
- Potentially slower performance when executing a lot of lines that
change `$env.config` one after another. Recommended to get `$env.config`
into a `mut` variable first and do modifications, then assign it back.
- Much faster performance when executing a script that made
modifications to `$env.config`, as the changes are only parsed once.
# Tests + Formatting
All passing.

# Description
Add a few more options to `view ir` for finding blocks, which I found
myself wanting while trying to trace through the generated code.
If we end up adding support for plugins to call commands that are in
scope by name, this will also make it possible for
`nu_plugin_explore_ir` to just step through IR automatically (by passing
the block/decl ids) without exposing too many internals. With that I
could potentially add keys that allow you to step in to closures or
decls with the press of a button, just by calling `view ir --json`
appropriately.
# User-Facing Changes
- `view ir` can now take names of custom commands that are in scope.
- integer arguments are treated as block IDs, which sometimes show up in
IR (closure, block, row condition literals).
- `--decl-id` provided to treat the argument as a decl ID instead, which
is also sometimes necessary to access something that isn't in scope.
# Description
Fix `view ir` to use `Signature::build()` rather than `new()`, which is
required for `--help` to work. Also add `Category::Debug`, as that's
most appropriate.
# Description
`Signature::get_positional()` was returning an owned `PositionalArg`,
which contains a bunch of strings. `ClosureEval` uses this in
`try_add_arg`, making all of that unnecessary cloning a little bit hot.
# User-Facing Changes
Slightly better performance
# Description
Just more efficient allocation during `Stack::gather_captures()` so that
we don't have to grow the `Vec` needlessly.
# User-Facing Changes
Slightly better performance.
# Description
Was having an issue compiling main after the IR pr. Talked to devyn and
he led me to change a couple things real quick and we're compiling once
again.
# Description
This is another easy performance lift that just changes `env_vars` and
`env_hidden` on `Stack` to use `Arc`. I noticed that these were being
cloned on essentially every closure invocation during captures
gathering, so we're paying the cost for all of that even when we don't
change anything. On top of that, for `env_vars`, there's actually an
entirely fresh `HashMap` created for each child scope, so it's highly
unlikely that we'll modify the parent ones.
Uses `Arc::make_mut` instead to take care of things when we need to
mutate something, and most of the time nothing has to be cloned at all.
# Benchmarks
The benefits are greater the more calls there are to env-cloning
functions like `captures_to_stack()`. Calling custom commands in a loop
is basically best case for a performance improvement. Plain `each` with
a literal block isn't so badly affected because the stack is set up
once.

# User-Facing Changes
Better performance, particularly for custom commands, especially if
there are a lot of environment variables. Nothing else.
# Tests + Formatting
All passing.
# Description
This PR adds an internal representation language to Nushell, offering an
alternative evaluator based on simple instructions, stream-containing
registers, and indexed control flow. The number of registers required is
determined statically at compile-time, and the fixed size required is
allocated upon entering the block.
Each instruction is associated with a span, which makes going backwards
from IR instructions to source code very easy.
Motivations for IR:
1. **Performance.** By simplifying the evaluation path and making it
more cache-friendly and branch predictor-friendly, code that does a lot
of computation in Nushell itself can be sped up a decent bit. Because
the IR is fairly easy to reason about, we can also implement
optimization passes in the future to eliminate and simplify code.
2. **Correctness.** The instructions mostly have very simple and
easily-specified behavior, so hopefully engine changes are a little bit
easier to reason about, and they can be specified in a more formal way
at some point. I have made an effort to document each of the
instructions in the docs for the enum itself in a reasonably specific
way. Some of the errors that would have happened during evaluation
before are now moved to the compilation step instead, because they don't
make sense to check during evaluation.
3. **As an intermediate target.** This is a good step for us to bring
the [`new-nu-parser`](https://github.com/nushell/new-nu-parser) in at
some point, as code generated from new AST can be directly compared to
code generated from old AST. If the IR code is functionally equivalent,
it will behave the exact same way.
4. **Debugging.** With a little bit more work, we can probably give
control over advancing the virtual machine that `IrBlock`s run on to
some sort of external driver, making things like breakpoints and single
stepping possible. Tools like `view ir` and [`explore
ir`](https://github.com/devyn/nu_plugin_explore_ir) make it easier than
before to see what exactly is going on with your Nushell code.
The goal is to eventually replace the AST evaluator entirely, once we're
sure it's working just as well. You can help dogfood this by running
Nushell with `$env.NU_USE_IR` set to some value. The environment
variable is checked when Nushell starts, so config runs with IR, or it
can also be set on a line at the REPL to change it dynamically. It is
also checked when running `do` in case within a script you want to just
run a specific piece of code with or without IR.
# Example
```nushell
view ir { |data|
mut sum = 0
for n in $data {
$sum += $n
}
$sum
}
```
```gas
# 3 registers, 19 instructions, 0 bytes of data
0: load-literal %0, int(0)
1: store-variable var 904, %0 # let
2: drain %0
3: drop %0
4: load-variable %1, var 903
5: iterate %0, %1, end 15 # for, label(1), from(14:)
6: store-variable var 905, %0
7: load-variable %0, var 904
8: load-variable %2, var 905
9: binary-op %0, Math(Plus), %2
10: span %0
11: store-variable var 904, %0
12: load-literal %0, nothing
13: drain %0
14: jump 5
15: drop %0 # label(0), from(5:)
16: drain %0
17: load-variable %0, var 904
18: return %0
```
# Benchmarks
All benchmarks run on a base model Mac Mini M1.
## Iterative Fibonacci sequence
This is about as best case as possible, making use of the much faster
control flow. Most code will not experience a speed improvement nearly
this large.
```nushell
def fib [n: int] {
mut a = 0
mut b = 1
for _ in 2..=$n {
let c = $a + $b
$a = $b
$b = $c
}

[random-bytes.nu](https://github.com/nushell/nu_scripts/blob/main/benchmarks/random-bytes.nu)
I got pretty random results out of this benchmark so I decided not to
include it. Not clear why.
# User-Facing Changes
- IR compilation errors may appear even if the user isn't evaluating
with IR.
- IR evaluation can be enabled by setting the `NU_USE_IR` environment
variable to any value.
- New command `view ir` pretty-prints the IR for a block, and `view ir
--json` can be piped into an external tool like [`explore
ir`](https://github.com/devyn/nu_plugin_explore_ir).
# Tests + Formatting
All tests are passing with `NU_USE_IR=1`, and I've added some more eval
tests to compare the results for some very core operations. I will
probably want to add some more so we don't have to always check
`NU_USE_IR=1 toolkit test --workspace` on a regular basis.
# After Submitting
- [ ] release notes
- [ ] further documentation of instructions?
- [ ] post-release: publish `nu_plugin_explore_ir`
# Description
Fixes the lexer to recognize `out>|`, `err>|`, `out+err>|`, etc.
Previously only the short-style forms were recognized, which was
inconsistent with normal file redirections.
I also integrated it all more into the normal lex path by checking `|`
in a special way, which should be more performant and consistent, and
cleans up the code a bunch.
Closes#13331.
# User-Facing Changes
- Adds `out>|` (error), `err>|`, `out+err>|`, `err+out>|` as recognized
forms of the pipe redirection.
# Tests + Formatting
All passing. Added tests for the new forms.
# After Submitting
- [ ] release notes
# Description
Makes `polars unpivot` use the same arguments as `polars pivot` and
makes it consistent with the polars' rust api. Additionally, support for
the polar's streaming engine has been exposed on eager dataframes.
Previously, it would only work with lazy dataframes.
# User-Facing Changes
* `polars unpivot` argument `--columns`|`-c` has been renamed to
`--index`|`-i`
* `polars unpivot` argument `--values`|`-v` has been renamed to
`--on`|`-o`
* `polars unpivot` short argument for `--streamable` is now `-t` to make
it consistent with `polars pivot`. It was made `-t` for `polars pivot`
because `-s` is short for `--short`

# Description
This PR introduces a new `Signals` struct to replace our adhoc passing
around of `ctrlc: Option<Arc<AtomicBool>>`. Doing so has a few benefits:
- We can better enforce when/where resetting or triggering an interrupt
is allowed.
- Consolidates `nu_utils::ctrl_c::was_pressed` and other ad-hoc
re-implementations into a single place: `Signals::check`.
- This allows us to add other types of signals later if we want. E.g.,
exiting or suspension.
- Similarly, we can more easily change the underlying implementation if
we need to in the future.
- Places that used to have a `ctrlc` of `None` now use
`Signals::empty()`, so we can double check these usages for correctness
in the future.

This is an internal refactoring for `explore`.
Previously, views inside `explore` were created with default/incorrect
configuration and then the correct configuration was passed to them
using a function called `setup()`. I believe this was because
configuration was dynamic and could change while `explore` was running.
After https://github.com/nushell/nushell/pull/10259, configuration can
no longer be changed on the fly. So we can clean this up by removing
`setup()` and passing configuration to views when they are created.
# Description
Fix `into bits` to have consistent behavior when passed a byte stream.
# User-Facing Changes
Previously, it was returning a binary on stream, even though its
input/output types don't describe this possibility. We don't need this
since we have `into binary` anyway.

# Description
fixed#12699
When bare dates or naive times are specified in toml files, `from toml`
returns invalid dates or times.
This PR fixes the problem to correctly handle toml datetime.
The current version command returns the default datetime
(`chrono::DateTime::default()`) if the datetime parse fails. However, I
felt that this behavior was a bit unfriendly, so I changed it to return
`Value::string`.
# User-Facing Changes
The command returns a date with default time and timezone if a bare date
is specified.
```

╭─────┬────────────╮

Sat, 27 May 2023 00:00:00 +0000 (a year ago)

```
If a bare time is given, a time string is returned.
```

# Description
Bug fix: `PipelineData::check_external_failed()` was not preserving the
original `type_` and `known_size` attributes of the stream passed in for
streams that come from children, so `external-command | into binary` did
not work properly and always ended up still being unknown type.
# User-Facing Changes
The following test case now works as expected:
```nushell
> head -c 2 /dev/urandom | into binary
# Expected: pretty hex dump of binary
# Previous behavior: just raw binary in the terminal

Exotic types like `Duration` and `Filesize` return a float on division
by the same type, i.e., the unit is gone since division results in a
scalar. When using the modulo operator, the output type has the same
unit.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

Division results in a float like the following:
```sh
~/Public/nushell> 512sec / 3sec
170.66666666666666
```
Modulo results in an output with the same unit:
```sh
~/Public/nushell> 512sec mod 3sec
2sec
```
Type checking isn't confused with output types:
```sh
~/Public/nushell> (512sec mod 3sec) / 0.5sec
4

This PR fixes an issue with `explore` where you can "drill down" into
the same value forever. For example:
1. Run `ls | explore`
2. Press Enter to enter cursor mode
3. Press Enter again to open the selected string in a new layer
4. Press Enter again to open that string in a new layer
5. Press Enter again to open that string in a new layer
6. Repeat and eventually you have a bajillion layers open with the same
string
IMO it only makes sense to "drill down" into lists and records.
In a separate commit I also did a little refactoring, cleaning up naming
and comments.
# Description
Fixes: #13189
The issue is caused `error make` returns a `Value::Errror`, and when
nushell pass it to `table -e` in `std help`, it directly stop and render
the error message.
To solve it, I think it's safe to make these examples return None
directly, it doesn't change the reult of `help error make`.

This PR fixes the problem pointed out in
https://github.com/nushell/nushell/issues/13204, where the Fish-like
completions aren't sorted properly (this PR doesn't close that issue
because the author there wants more than just fixed sort order).
The cause is all of the file/directory completions being fetched first
and then sorted all together while being treated as strings. Instead,
this PR sorts completions within each individual directory, avoiding
treating `/` as part of the path.
To do this, I removed the `sort` method from the completer trait (as
well as `get_sort_by`) and made all completers sort within the `fetch`
method itself. A generic `sort_completions` helper has been added to
sort lists of completions, and a more specific `sort_suggestions` helper
has been added to sort `Vec<Suggestion>`s.
As for the actual change that fixes the sort order for file/directory
completions, the `complete_rec` helper now sorts the children of each
directory before visiting their children. The file and directory
completers don't bother sorting at the end (except to move hidden files
down).
To reviewers: don't let the 29 changed files scare you, most of those
are just the test fixtures :)

This is the current behavior with prefix matching:
And with fuzzy matching:
Notice how `partial/hello.txt` is the last suggestion, even though it
should come before `partial-a`. This is because the ASCII code for `/`
is greater than that of `-`, so `partial-` is put before `partial/`.
This is this PR's behavior with prefix matching (`partial/hello.txt` is
at the start):

# Description
With #13254, the content-type pipeline metadata field was added. This
pull request allows it to be manipulated with `metadata set`
# User-Facing Changes
* `metadata set` now has a `--content-type` flag
# Description
Provides the ability to use http commands as part of a pipeline.
Additionally, this pull requests extends the pipeline metadata to add a
content_type field. The content_type metadata field allows commands such
as `to json` to set the metadata in the pipeline allowing the http
commands to use it when making requests.
This pull request also introduces the ability to directly stream http
requests from streaming pipelines.
One other small change is that Content-Type will always be set if it is
passed in to the http commands, either indirectly or throw the content
type flag. Previously it was not preserved with requests that were not
of type json or form data.
# User-Facing Changes
* `http post`, `http put`, `http patch`, `http delete` can be used as
part of a pipeline
* `to text`, `to json`, `from json` all set the content_type metadata
field and the http commands will utilize them when making requests.
# Description
I introduced a regression in #13272 that resulted in `detect columns
--guess` to panic whenever it had to handle empty, whitespace-only, or
non-whitespace-only lines that go all the way to the last column (and as
such, cannot be considered to be lines that only have entries for the
first colum). I fix this by detecting these cases and skipping them,
since these are usually decoration lines. An example is the second line
output by `winget list`:
What we don't want to skip, however, is lines that contain no
whitespace, and fit into the detected first column, since these lines
represent cases where data is only available for the first column, and
are not just decoration lines. For example (made up example, there are
no such entries in `winget lits`'s output), in this output we would not
want to skip the `Docker Desktop` line :
```
Name Id Version Available Source
-------------------------------------------------------------------------------------------------------------------------------------
AMD Software ARPMachineX64AMD Catalyst Install Manager 24.4.1
AMD Ryzen Master ARPMachineX64AMD Ryzen Master 2.13.0.2908
Docker Desktop
Mozilla Firefox (x64 en-US) Mozilla.Firefox 127.0.2 winget
```
NOTE: `winget list | detect columns --guess` does not panic, but sadly
still does not work as expected. I believe this is not a nushell issue
anymore, but a `winget` one. When being piped, `winget` seems to add
extra whitespace and random `\r` symbols at the beginning of the text.
This messes with the column detection, of course.
# User-Facing Changes
`detect columns --guess` should not panic when receiving output from
`winget list` at all anymore.
A breaking change is the skipping of decoration lines, especially since
scripts probably were doing something like
`winget list | lines | reject 1 | str join "\n" | detect columns
--guess`. This will now cause them to reject a line with valid data.

# Description
Fixes one of the issues described in #13125
The `do` signature included a `SyntaxShape:Any` as one of the possible
first-positional types. This is incorrect. `do` only takes a closure as
a positional. This had the result of:
1. Moving what should have been a parser error to evaluation-time
## Before
```nu
> do 1
Error: nu:🐚:cant_convert
× Can't convert to Closure.
╭─[entry #26:1:4]
1 │ do 1
· ┬
· ╰── can't convert int to Closure
╰────
```
## After
```nu
> do 1
Error: nu::parser::parse_mismatch
× Parse mismatch during operation.
╭─[entry #5:1:4]
1 │ do 1
· ┬
· ╰── expected block, closure or record
╰────
```
2. Masking a bad test in `std assert`
This is a bit convoluted, but `std assert` tests included testing
`assert error` to make sure it:
* Asserts on bad code
* Doesn't assert on good code
The good-code test was broken, and was essentially bad-code (really
bad-code) that wasn't getting caught due to the bad signature.
Fixing this resulted in *parse time* failures on every call to
`test_asserts` (not something that particular test was designed to
handle.
This PR also fixes the test case to properly evaluate `std assert error`
against a good code path.

This PR adds a new subcommand `query webpage-info` to `plugin_nu_query`.
The subcommand is a basic wrapper for the
[`webpage`](https://crates.io/crates/webpage) crate.
Usage:
```
http get https://phoronix.com | query webpage-info
```
and it returns a `Record` version of
[`webpage::HTML`](https://docs.rs/webpage/latest/webpage/struct.HTML.html).
The PR also takes a shot at bringing @lily-mara 's
[nu-serde::to_value](https://github.com/nushell/nushell/pull/3878/files)
back to life, updating it for the latest version of nushell. That's not
the main focus of the PR though - I just didn't want to have to
implement a custom converter for `webpage::HTML` 😅. If it looks
reasonable we could move it to `nu_protocol`(?) either in this PR or a
future one (along with adding tests for it).

This PR fixes#13269. The splitting code in `guess_width.rs` was
creating slices from char indices, instead of byte indices. This works
perfectly fine for 1-byte code points, but panics or returns wrong
results as soon as multibyte codepoints appear in the input. I
originally discovered this by piping `winget list` into `detect columns
--guess`, since winget sometimes uses the unicode ellipsis symbol (`…`)
which is 3 bytes long when encoded in utf-8.

# Description
The standard library's `path add` function has some surprising side
effects that I attempt to address in this PR:
1. Paths added, if they are symbolic links, should not be resolved to
their targets. Currently, resolution happens.
Imagine the following:
```nu
# Some time earlier, perhaps even not by the user, a symlink is created
mkdir real-dir
ln -s real-dir link-dir
# Then, step to now, with link-dir that we want in our PATHS variable
use std
path add link-dir
```
In the current implementation of `path add`, it is _not_ `link-dir` that
will be added, as has been stated in the command. It is instead
`real-dir`. This is surprising. Users have the agency to do this
resolution if they wish with `path expand` (sans a `--no-symlink` flag):
for example, `path add (link-dir | path expand)`
In particular, when I was trying to set up
[fnm](https://github.com/Schniz/fnm), a Node.js version manager, I was
bitten by this fact when `fnm` told me that an expected path had not
been added to the PATHS variable. It was looking for the non-resolved
link. The user in [this
comment](https://github.com/Schniz/fnm/issues/463#issuecomment-1710050737)
was likely affected by this too.
Shells, such as nushell, can handle path symlinks just fine. Binary
lookup is unaffected. Let resolution be opt-in.
Lastly, there is some convention already in place for **not** resolving
path symlinks in the [default $env.ENV_CONVERSIONS
table](57452337ff/crates/nu-utils/src/sample_config/default_env.nu (L65)).
2. All existing paths in the path variable should be left untouched.
Currently, they are `path expand`-ed (including symbolic link
resolution).
Path add should mean just that: prepend/append this path.
Instead, it currently means that, _plus mutate all other paths in the
variable_.
Again, users have the agency to do this with something like `$env.PATH =
$env.PATH | split row (char esep) | path expand`.
3. Minorly, I update documentation on running tests in
`crates/nu-std/CONTRIBUTING.md`. The offered command to run the standard
library test suite was no longer functional. Thanks to @weirdan in [this
Discord
conversation](https://discord.com/channels/601130461678272522/614593951969574961/1256029201119576147)
for the context.
# User-Facing Changes
(Written from the perspective of release notes)
- The standard library's `path add` function no longer resolves symlinks
in either the newly added paths, nor the other paths already in the
variable.
# Tests + Formatting
A test for the changes working correctly has been added to
`crates/nu-std/tests/test_std.nu` under the test named
`path_add_expand`.
You can quickly verify this new test and the existing `path add` test
with the following command:
```nu
cargo run -- -c 'use crates/nu-std/testing.nu; NU_LOG_LEVEL=INFO testing run-tests --path crates/nu-std --test path_add'
```
All commands suggested in the issue template have been run and complete
without error.
# After Submitting
I'll add a release note to [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged.
# Description
Allows specifying multiple attributes to retrieve from the selected
nodes. E.g. you may want to select both hrefs and targets from the list
of links:
```nushell
.... | query web --query a --attribute [href target]
```
# User-Facing Changes
`query web --attribute` previously accepted a string. Now it accepts
either a string or a list of strings.
The shape definition for this flag was relaxed temporarily, until
nushell/nushell#13253 is fixed.
# Description
Upgrading to Polars 0.41
# User-Facing Changes
* `polars melt` has been renamed to `polars unpivot` to match the change
in the polars API. Additionally, it now supports lazy dataframes.
Introduced a `--streamable` option to use the polars streaming engine
for lazy frames.
* The parameter `outer` has been replaced with `full` in `polars join`
to match polars change.
* `polars value-count` now supports the column (rename count column),
parallelize (multithread), sort, and normalize options.
The list of polars changes can be found
[here](https://github.com/pola-rs/polars/releases/tag/rs-0.41.2)
# Description
This might help @hustcer debug problems with `setup-nu`. The error
messages with the file I/O in `modify_plugin_file()` are not currently
not specific about what file path was involved in the I/O operation.
The spans on those errors have also changed to the span of the custom
path if provided.
# User-Facing Changes
- Slightly better error
In this pull request, I converted the `perf` function within `nu_utils`
to a macro. This change facilitates easier usage within plugins by
allowing the use of `env_logger` and setting `RUST_LOG=nu_plugin_polars`
(or another plugin). Without this conversion, the `RUST_LOG` variable
would need to be set to `RUST_LOG=nu_utils::utils`, which is less
intuitive and impossible to narrow the perf results to one plugin.

# Description
This PR adds new types to `nu-path` to enforce path invariants. Namely,
this PR adds:
- `Path` and `PathBuf`. These types are different from, but analogous to
`std::path::Path` and `std::path::PathBuf`.
- `RelativePath` and `RelativePathBuf`. These types must be/contain
strictly relative paths.
- `AbsolutePath` and `AbsolutePathBuf`. These types must be/contain
strictly absolute paths.
- `CanonicalPath` and `CanonicalPathBuf`. These types must be/contain
canonical paths.
Operations are prohibited as necessary to ensure that the invariants of
each type are upheld (needs double-checking).
Only paths that are absolute (or canonical) can be easily used as /
converted to `std::path::Path`s. This is to help force us to account for
the emulated current working directory instead of accidentally using the
current directory of the Nushell process (i.e.,
`std::env::current_dir`). Related to #12975 and #12976.
Note that this PR uses several declarative macros, as the file / this PR
would otherwise be 5000 lines long.
# User-Facing Changes
No major changes yet, just adds types to `nu-path` to be used in the
future.
# After Submitting
Actually use the new path types in all our crates where it makes sense,
removing usages of `std::path` types.
# Description
Fixes: https://github.com/nushell/nushell/issues/12099
Currently if user run `use voice.nu`, and file is unchanged, then run
`use voice.nu` again. nushell will use the module directly, even if
submodule inside `voice.nu` is changed.
After discussed with @kubouch, I think it's ok to re-parse the module
file when:
1. It exports sub modules which are defined by a file
2. It uses other modules which are defined by a file
## About the change:
To achieve the behavior, we need to add 2 attributes to `Module`:
1. `imported_modules`: it tracks the other modules is imported by the
givem `module`, e.g: `use foo.nu`
2. `file`: the path of a module, if a module is defined by a file, it
will be `Some(path)`, or else it will be `None`.
After the change:
use voice.nu always read the file and parse it.

# Description
Some commands in `nu-cmd-lang` are not classified as keywords even
though they should be.
# User-Facing Changes
In the output of `which`, `scope commands`, and `help commands`, some
commands will now have a `type` of `keyword` instead of `built-in`.

This PR implements script or module autoloading. It does this by finding
the `$nu.vendor-autoload-dir`, lists the contents and sorts them by file
name. These files are evaluated in that order.

# Description
@hustcer reported that slashes were disappearing from external args
since #13089:
```
$> ossutil ls oss://abc/b/c
Error: invalid cloud url: "oss:/abc/b/c", please make sure the url starts with: "oss://"
$> ossutil ls 'oss://abc/b/c'
Error: oss: service returned error: StatusCode=403, ErrorCode=UserDisable, ErrorMessage="UserDisable", RequestId=66791EDEFE87B73537120838, Ec=0003-00000801, Bucket=abc, Object=
```
I narrowed this down to the ndots handling, since that does path parsing
and path reconstruction in every case. I decided to change that so that
it only activates if the string contains at least `...`, since that
would be the minimum trigger for ndots, and also to not activate it if
the string contains `://`, since it's probably undesirable for a URL.
Kind of a hack, but I'm not really sure how else we decide whether
someone wants ndots or not.
# User-Facing Changes
- bare strings not containing ndots are not modified
- bare strings containing `://` are not modified

Fixesnushell/nushell#13207
# Description
This fixes the parsing of command usage when that command comes from a
file with CRLF line endings.
See nushell/nushell#13207 for more details.
# User-Facing Changes
Users on Windows will get correct autocompletion for `std` commands.
# Description
In #13031 I added the derive macros for `FromValue` and `IntoValue`. In
that implementation, in particular for structs with named fields, it was
not possible to omit fields while loading them from a value, when the
field is an `Option`. This PR adds extra handling for this behavior, so
if a field is an `Option` and that field is missing in the `Value`, then
the field becomes `None`. This behavior is also tested in
`nu_protocol::value::test_derive::missing_options`.
# User-Facing Changes
When using structs for options or similar, users can now just emit
fields in the record and the derive `from_value` method will be able to
understand this, if the struct has an `Option` type for that field.

# After Submitting
A showcase for this feature would be great, I tried to use the current
derive macro in a plugin of mine for a config but without this addition,
they are annoying to use. So, when this is done, I would add an example
for such plugin configs that may be loaded via `FromValue`.
# Description
* As discussed in the comments in #11954, this suppresses the index
column on `cal` output. It does that by running `table -i false` on the
results by default.
* Added new `--as-table/-t` flag to revert to the old behavior and
output the calendar as structured data
* Updated existing tests to use `--as-table`
* Added new tests against the string output
* Updated `length` test which also used `cal`
* Added new example for `--as-table`, with result
# User-Facing Changes
## Breaking change
The *default* `cal` output has changed from a `list` to a `string`. To
obtain structured data from `cal`, use the new `--as-table/-t` flag.

# Description
Removes `list<any>` as an input type for the `generate` command. This
command does not accept pipeline input (and cannot, logically). This can
be seen by the use of `_input` in the command's `run()`.
Also, due to #13199, in order to pass `toolkit check pr`, one of the
examples was changed to remove the `result`. This is probably a better
demonstration of the ability of the command to infinitely generate a
list anyway, and an infinite list can't be represented in a `result`.
# User-Facing Changes
Should only be a change to the help. The input type was never valid and
couldn't have been used.

Addresses performance issues that @maxim-uvarov found with CSV and JSON
lines.
This ensures that the schema inference follows the polars defaults of
100 lines. Recent changes caused the default values to be override and
caused the entire file to be scanned when inferring the schema.
Somehow I believe that split lines were implemented originally; (I
haven't got to find it though; from a quick look)
I mean a long time ago before a lot a changes were made.
Probably adding horizontal lines would make also some sense.

If `explore` is used, frequently, or planned to be so.
I guess it would be a good one to create a test suite for it; to not
break things occasionally 😅
I did approached it one time back then using `expectrl` (literally
`expect`), but there was some issues.
Maybe smth. did change.
Or some `clean` mode could be introduced for it, to being able to be
used by outer programs; to control `nu`.
Just thoughts here.
# Description
This allows plugins to report their version (and potentially other
metadata in the future). The version is shown in `plugin list` and in
`version`.
The metadata is stored in the registry file, and reflects whatever was
retrieved on `plugin add`, not necessarily the running binary. This can
help you to diagnose if there's some kind of mismatch with what you
expect. We could potentially use this functionality to show a warning or
error if a plugin being run does not have the same version as what was
in the cache file, suggesting `plugin add` be run again, but I haven't
done that at this point.
It is optional, and it requires the plugin author to make some code
changes if they want to provide it, since I can't automatically
determine the version of the calling crate or anything tricky like that
to do it.
Example:
```
> plugin list | select name version is_running pid
╭───┬────────────────┬─────────┬────────────┬─────╮
│ # │ name │ version │ is_running │ pid │
├───┼────────────────┼─────────┼────────────┼─────┤

# Description
Just missed this during #13089. Adds `shape_glob_interpolation` to the
config.
This actually isn't really going to be seen at all yet, so I debated
whether it's really needed at all. It's only used to highlight the
quotes themselves, and we don't have any quoted glob interpolations at
the moment.
# Description
Fixes#13194
`ki_stat` is supposed to be a `c_char`, but was defined was `i8`.
Unfortunately, `c_char` is `u8` on Aarch64 (on all platforms), so this
doesn't compile. I fixed it to use `c_char` instead.
Double checked whether NetBSD is affected, but the `libc` code defines
it as `i8` for some reason (erroneously, really) but that doesn't matter
too much. Anyway should be ok there.
Confirmed to be working.
# Description
#12056 added support for default and type-checked arguments in `do`

This allows performance debugging to be turned on by setting:
```nushell
$env.POLARS_PLUGIN_PERF = "true"
```
Furthermore, this improves the other plugin debugging by allowing the
env variable for debugging to be set at any time versus having to be
available when nushell is launched:
```nushell
$env.POLARS_PLUGIN_DEBUG = "true"
```
This plugin introduces a `perf` function that will output timing
results. This works very similar to the perf function available in
nu_utils::utils::perf. This version prints everything to std error to
not break the plugin stream and uses the engine interface to see if the
env variable is configured.
This pull requests uses this `perf` function when:
* opening csv files as dataframes
* opening json lines files as dataframes
This will hopefully help provide some more fine grained information on
how long it takes polars to open different dataframes. The `perf` can
also be utilized later for other dataframes use cases.
# Description
This PR adds a directory to the `$nu` constant that shows where the
system level autoload directory is located at. This folder is modifiable
at compile time with environment variables.
```rust
// Create a system level directory for nushell scripts, modules, completions, etc
// that can be changed by setting the NU_VENDOR_AUTOLOAD_DIR env var on any platform
// before nushell is compiled OR if NU_VENDOR_AUTOLOAD_DIR is not set for non-windows
// systems, the PREFIX env var can be set before compile and used as PREFIX/nushell/vendor/autoload
// pseudo code
// if env var NU_VENDOR_AUTOLOAD_DIR is set, in any platform, use it
// if not, if windows, use ALLUSERPROFILE\nushell\vendor\autoload
// if not, if non-windows, if env var PREFIX is set, use PREFIX/share/nushell/vendor/autoload
// if not, use the default /usr/share/nushell/vendor/autoload
```
### Windows default
```nushell
❯ $nu.vendor-autoload-dir
C:\ProgramData\nushell\vendor\autoload
```
### Non-Windows default
```nushell
❯ $nu.vendor-autoload-dir
/usr/local/share/nushell/vendor/autoload
```
### Non-Windows with PREFIX set
```nushell
❯ PREFIX=/usr/bob cargo r
❯ $nu.vendor-autoload-dir
/usr/bob/share/nushell/vendor/autoload
```
### Non-Windows with NU_VENDOR_AUTOLOAD_DIR set
```nushell
❯ NU_VENDOR_AUTOLOAD_DIR=/some/other/path/nushell/stuff cargo r
❯ $nu.vendor-autoload-dir
/some/other/path/nushell/stuff
```
> [!IMPORTANT]
To be clear, this PR does not do the auto-loading, it just sets up the
folder to support that functionality that can be added in a later PR.
The PR also does not create the folder defined. It's just setting the
$nu constant.

# Description
We've had a lot of different issues and PRs related to arg handling with
externals since the rewrite of `run-external` in #12921:
- #12950
- #12955
- #13000
- #13001
- #13021
- #13027
- #13028
- #13073
Many of these are caused by the argument handling of external calls and
`run-external` being very special and involving the parser handing
quoted strings over to `run-external` so that it knows whether to expand
tildes and globs and so on. This is really unusual and also makes it
harder to use `run-external`, and also harder to understand it (and
probably is part of the reason why it was rewritten in the first place).
This PR moves a lot more of that work over to the parser, so that by the
time `run-external` gets it, it's dealing with much more normal Nushell
values. In particular:
- Unquoted strings are handled as globs with no expand
- The unescaped-but-quoted handling of strings was removed, and the
parser constructs normal looking strings instead, removing internal
quotes so that `run-external` doesn't have to do it
- Bare word interpolation is now supported and expansion is done in this
case
- Expressions typed as `Glob` containing `Expr::StringInterpolation` now
produce `Value::Glob` instead, with the quoted status from the expr
passed through so we know if it was a bare word
- Bare word interpolation for values typed as `glob` now possible, but
not implemented
- Because expansion is now triggered by `Value::Glob(_, false)` instead
of looking at the expr, externals now support glob types
# User-Facing Changes
- Bare word interpolation works for external command options, and
otherwise embedded in other strings:
```nushell
^echo --foo=(2 + 2) # prints --foo=4
^echo -foo=$"(2 + 2)" # prints -foo=4
^echo foo="(2 + 2)" # prints (no interpolation!) foo=(2 + 2)
^echo foo,(2 + 2),bar # prints foo,4,bar
```
- Bare word interpolation expands for external command head/args:
```nushell
let name = "exa"
~/.cargo/bin/($name) # this works, and expands the tilde
^$"~/.cargo/bin/($name)" # this doesn't expand the tilde
^echo ~/($name)/* # this glob is expanded
^echo $"~/($name)/*" # this isn't expanded
```
- Ndots are now supported for the head of an external command
(`^.../foo` works)
- Glob values are now supported for head/args of an external command,
and expanded appropriately:
```nushell
^("~/.cargo/bin/exa" | into glob) # the tilde is expanded
^echo ("*.txt" | into glob) # this glob is expanded
```
- `run-external` now works more like any other command, without
expecting a special call convention
for its args:
```nushell
run-external echo "'foo'"
# before PR: 'foo'
# after PR: foo
run-external echo "*.txt"
# before PR: (glob is expanded)
# after PR: *.txt
```
# Tests + Formatting
Lots of tests added and cleaned up. Some tests that weren't active on
Windows changed to use `nu --testbin cococo` so that they can work.
Added a test for Linux only to make sure tilde expansion of commands
works, because changing `HOME` there causes `~` to reliably change.

# Description
Mostly fixes#13149 with much of the credit to @fdncred.
This PR runs `table --expand` against `help` example results. This is
essentially the same fix that #13146 was for `std help`.
It also changes the shape of the result for the `table --expand`
example, as it was hardcoded wrong.
~Still needed is a fix for the `table --collapse` example.~ Note that
this is also still a bug in `std help` that I didn't noticed before.

Surprisingly, all of the tests pass, including in small windows! I only
had to make one change to a test for `error make` which was looking for
the box drawing characters miette uses to determine whether the span
label was showing up - but the plain error style output is even better
and easier to match on, so this test is actually more specific now.

# Description
Fixes: #13105Fixes: #13077
This pr makes `str substring`, `bytes at` work better with negative
index.
And it also fixes the false range semantic on `detect columns -c` in
some cases.
# User-Facing Changes
For `str substring`, `bytes at`, it will no-longer return an error if
start index is larger than end index. It makes sense to return an empty
string of empty bytes directly.

# Description
After discussing with @sholderbach the cumbersome usage of
`nu_protocol::Value` in Rust, I created a derive macro to simplify it.
I’ve added a new crate called `nu-derive-value`, which includes two
macros, `IntoValue` and `FromValue`. These are re-exported in
`nu-protocol` and should be encouraged to be used via that re-export.
The macros ensure that all types can easily convert from and into
`Value`. For example, as a plugin author, you can define your plugin
configuration using a Rust struct and easily convert it using
`FromValue`. This makes plugin configuration less of a hassle.
I introduced the `IntoValue` trait for a standardized approach to
converting values into `Value` (and a fallible variant `TryIntoValue`).
This trait could potentially replace existing `into_value` methods.
Along with this, I've implemented `FromValue` for several standard types
and refined other implementations to use blanket implementations where
applicable.
I made these design choices with input from @devyn.
There are more improvements possible, but this is a solid start and the
PR is already quite substantial.
# User-Facing Changes
For `nu-protocol` users, these changes simplify the handling of
`Value`s. There are no changes for end-users of nushell itself.
# Tests + Formatting
Documenting the macros itself is not really possible, as they cannot
really reference any other types since they are the root of the
dependency graph. The standard library has the same problem
([std::Debug](https://doc.rust-lang.org/stable/std/fmt/derive.Debug.html)).
However I documented the `FromValue` and `IntoValue` traits completely.
For testing, I made of use `proc-macro2` in the derive macro code. This
would allow testing the generated source code. Instead I just tested
that the derived functionality is correct. This is done in
`nu_protocol::value::test_derive`, as a consumer of `nu-derive-value`
needs to do the testing of the macro usage. I think that these tests
should provide a stable baseline so that users can be sure that the impl
works.
# After Submitting
With these macros available, we can probably use them in some examples
for plugins to showcase the use of them.

# Description
Some command help has example results with nested `table` data which is
displayed as the "non-expanded" form. E.g.:
```nu
╭───┬────────────────╮
│ 0 │ [list 2 items] │
│ 1 │ [list 2 items] │
╰───┴────────────────╯
```
For a good example, see `help zip`.
While we could simply remove the offending Example `result`'s from the
command itself, `std help` is capable of expanding the table properly.
It already formats the output of each example result using `table`, so
simply making it a `table -e` fixes the output.
While I wish we had a way of expanding the tables in the builtin `help`,
that seems to be the same type of problem as in formatting the `cal`
output (see #11954).
I personally think it's better to add this feature to `std help` than to
remove the offending example results, but as long as `std help` is
optional, only a small percentage of users are going to see the
"expected" results.
# User-Facing Changes
Excerpt from `std help zip` before change:
```nu

> [1 2] | zip [3 4]
╭───┬────────────────╮
│ 0 │ [list 2 items] │
│ 1 │ [list 2 items] │
╰───┴────────────────╯
```
After:
```nu

# Description
In this PR, I continue my tradition of trivial but hopefully helpful
`help` tweaks. As mentioned in #13143, I noticed that `help -f else`
oddly didn't return the `if` statement itself. Perhaps not so oddly,
since who the heck is going to go looking for *"else"* in the help?
Well, I did ...
Added *"else"* and *"conditional"* to the search terms for `if`.
I'll work on the meat of #13143 next - That's more substantiative.

# Description
Removes the `which-support` cargo feature and makes all of its
feature-gated code enabled by default in all builds. I'm not sure why
this one command is gated behind a feature. It seems to be a relic of
older code where we had features for what seems like every command.
# Description
`help banner` had several issues:
* It used a Markdown link to an Asciinema recording, but Markdown links
aren't rendered as Markdown links by the help system (and can't be,
since (most?) terminals don't support that)
* Minor grammatical issues
* The Asciinema recording is out of date anyway. It still uses `use
stdn.nu banner` which isn't valid syntax any longer.
Since everyone at this point knows exactly what `banner` does 😉, I chose
to simply remove the link to the recording. Also tweaked the text
(initial caps and removed comma).

# Description
This PR is an attempt to add a standard location for people to put
completions in. I saw this topic come up again recently and IIRC we
decided to create a standard location. I used the dirs-next crate to
dictate where these locations are. I know some people won't like that
but at least this gets the ball rolling in a direction that has a
standard directory.
This is what the default NU_LIB_DIRS looks like now in the
default_env.nu. It should also be like this when starting nushell with
`nu -n`
```nushell
$env.NU_LIB_DIRS = [
($nu.default-config-dir | path join 'scripts') # add <nushell-config-dir>/scripts
($nu.data-dir | path join 'completions') # default home for nushell completions
]
```
I also added these default folders to the `$nu` variable so now there is
`$nu.data-path` and `$nu.cache-path`.
## Data Dir Default
While I was in there, I also decided to add a cache dir
## Cache Dir Default
### This is what the default looks like in Ubuntu.
### This is what it looks like with XDG_CACHE_HOME and XDG_DATA_HOME
overridden
```nushell
XDG_DATA_HOME=/tmp/data_home XDG_CACHE_HOME=/tmp/cache_home cargo r
```
### This is what the defaults look like in Windows (username scrubbed to
protect the innocent)
How my NU_LIB_DIRS is set in the images above
```nushell
$env.NU_LIB_DIRS = [
($nu.default-config-dir | path join 'scripts') # add <nushell-config-dir>/scripts
'/Users/fdncred/src/nu_scripts'
($nu.config-path | path dirname)
($nu.data-dir | path join 'completions') # default home for nushell completions
]
```
Let the debate begin.

# 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
```

# 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.

# Description
Removes the old, deprecated behavior of the `sys` command. That is, it
will no longer return the full system information record.
# User-Facing Changes
Breaking change: `sys` no longer outputs anything and will instead
display help text.
# 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
Per discussion on discord dataframes channel with @maxim-uvarov and pyz.
When converting a dataframe to an nushell value via `polars into-nu`,
the index column should not be added by default and should only be added
when specifying `--index`
