Expand tables in help examples in std (#13146)
# 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
Zip two lists
> [1 2] | zip [3 4]
╭───┬────────────────╮
│ 0 │ [list 2 items] │
│ 1 │ [list 2 items] │
╰───┴────────────────╯
```

After:

```nu
Zip two lists
> [1 2] | zip [3 4]
╭───┬───────────╮
│ 0 │ ╭───┬───╮ │
│   │ │ 0 │ 1 │ │
│   │ │ 1 │ 3 │ │

Fixed help for banner (#13138)
# 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* The Asciinema recording is out of date anyway.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).

complete the type of --error-label in std assert commands (#12998)
i was looking at the website documentation of `std assert` and i noticed
one thing
- the `--error-label` argument of `assert` and `assert not` was just a
`record` -> now it's that complete type `record<text: string, span:
record<start: int, end: int>>`

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.

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.

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.

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`

add type check during eval time (#11475)
# Description
Fixes: #11438 

Take the following as example:
```nushell
def spam [foo: string] {
    $'foo: ($foo | describe)'
}
def outer [--foo: string] {
    spam $foo
}

outer
```
When we call `outer`, type checker only check the all for `outer`, but
doesn't check inside the body of `outer`. This pr is trying to introduce
a type checking process through `Type::is_subtype()` during eval time.

## NOTE
I'm not really sure if it's easy to make a check inside the body of
`outer`. Adding an eval time type checker seems like an easier solution.
As a result: `outer` will be caught by runtime, not parse time type
checker

disable directory submodule auto export (#11157)
should
- close https://github.com/nushell/nushell/issues/11133

# Description
to allow more freedom when writing complex modules, we are disabling the
auto-export of director modules.

the change was as simple as removing the crawling of files and modules
next to any `mod.nu` and update the standard library.

# User-Facing Changes
users will have to explicitely use `export module <mod>` to define
submodules and `export use <mod> <cmd>` to re-export definitions, e.g.
```nushell
# my-module/mod.nu
export module foo.nu     # export a submodule
export use bar.nu bar-1  # re-export an internal command

export def top [] {
    print "`top` from `mod.nu`"
}
```
```nushell
# my-module/foo.nu
export def "foo-1" [] {
    print "`foo-1` from `lib/foo.nu`"
}

export def "foo-2" [] {
    print "`foo-2` from `lib/foo.nu`"
}
```
```nushell
# my-module/bar.nu
export def "bar-1" [] {
    print "`bar-1` from `lib/bar.nu`"
}
```

# Tests + Formatting
i had to add `export module` calls in the `tests/modules/samples/spam`
directory module and allow the `not_allowed` module to not give an
error, it is just empty, which is fine.

deprecate std testing (#11151)
# Description
this PR deprecates the `std testing` module in favor of Nupm.
the plan is to simply hide the module to the user but still use it
internally when running the tests so that
- users don't start to use this module and rather focus on Nupm
- devs don't have to install anything to run the tests locally, they can

deprecate std clip (#11097)
related to 
- https://github.com/nushell/nushell/issues/11041
- https://github.com/nushell/nu_scripts/pull/674

cc/ @FMotalleb 

# Description
reading the [frontpage of the standard
library](https://github.com/nushell/nushell/blob/main/crates/nu-std/README.md#--welcome-to-the-standard-library-of-nushell--)
and according to the last Nushell meeting, i has been agreed that `std
clip` does not belong to the standard library 😮
- it is not written in pure Nushell and requires external dependencies
which might not even work properly as in
https://github.com/nushell/nushell/issues/11041
- it is not a building block to build more complex applications

this PR deprecates the `std clip` command in favor of [`modules/system
clip`](https://github.com/nushell/nu_scripts/pull/674) for now.

the `std clip` command will be removed in Nushell 0.89.

# User-Facing Changes

> **Note**
> the link has been changed to the `nu_scripts` in fa6c17da0 according
to the review comments

std: add cross platform null-device name (#11070)
# Description
We have meet a discord discussion about cross platform `null-device`:
https://discord.com/channels/601130461678272522/988303282931912704/1165966467095875624

I want the same feature too...And I think it's good enough to add it
into `nu-std`.

Different to https://github.com/nushell/nu_scripts/pull/649/files, I
think named it to `null-device`(the name comes from
[wiki](https://en.wikipedia.org/wiki/Null_device)) is better than
`null-stream`.

Refactor error make (#10923)
- Replaced `start`/`end` with span.
- Fixed standard library.
- Add `help` option.
- Add a couple more errors for invalid record types.

Resolve #10914


# Description



# User-Facing Changes

- **BREAKING CHANGE:** `error make` now takes in `span` instead of
`start`/`end`:

  ```Nushell
  error make {
      msg: "Message"
      label: {
          text: "Label text"
          span: (metadata $var).span
      }
  }
  ```
- `error make` now has a `help` argument for custom error help.

group-by now returns a table instead of a record (#10848)
# Description

Previously `group-by` returned a record containing each group as a
column. This data layout is hard to work with for some tasks because you
have to further manipulate the result to do things like determine the
number of items in each group, or the number of groups. `transpose` will
turn the record returned by `group-by` into a table, but this is
expensive when `group-by` is run on a large input.

In a discussion with @fdncred [several
workarounds](https://github.com/nushell/nushell/discussions/10462) to
common tasks were discussed, but they seem unsatisfying in general.

Now when `group-by --to-table` is used a table is returned with the
columns "groups" and "items" making it easier to do things like count
the number of groups (`| length`) or count the number of items in each
group (`| each {|g| $g.items | length`)

# User-Facing Changes

* `group-by` returns a `table` with "group" and "items" columns instead
of a `record` with one column per group name

# Tests + Formatting

Tests for `group-by` were updated

# After Submitting

* No breaking changes were made. The new `--to-table` switch should be
added automatically to the [`group-by`
documentation](https://www.nushell.sh/commands/docs/group-by.html)

dirs goto: update current ring slot before leaving it. (#10706)
Fixes #10696

# Description

As reported, you could mess up the ring of remembered directories in
`std dirs` (a.k.a the `shells` commands) with a sequence like this:
```
~/test> mkdir b c

~/test> pushd b
~/test/b> cd ../c
~/test/c> goto 0
~/test> goto 1
## expect to end up in ~/test/c
## observe you're in ~/test/b
~/test/b>
```
Problem was `dirs goto` was not updating the remembered directories
before leaving the current slot for some other. This matters if the user
did a manual `cd` (which cannot update the remembered directories ring)

add to ndjson and to jsonl to the standard library (#10519)

# Description
even though it appears defining `to foo` does not allow to do `save
x.foo` for free (see https://github.com/nushell/nushell/issues/10429),
because #10283 did add `from ndjson` and `from jsonl` to the standard
library, i thought adding their `to ...` counterpart would make sense
😋

# User-Facing Changes
users can now convert structured data back to NDJSON and JSONL 👌

# Tests + Formatting
this PR adds the exact same tests as for the `from ...` commands
- structured data is in `result` and the string is now the expected
- the two invalid `from ...` tests cannot be reproduced for `to ...`

improve assertion error messages in std assert (#10551)
should close #10549 

# Description
this PR is twofold
- uses `to nuon --raw` in the error messages to make sure #10549 is
solved and makes a difference between `"1"` and `1`
- tries to introduce slightly better errors, i.e. by putting left /
right on new lines => this should hopefully help when the values become
a bit big 😋

std dt datetime-diff: fix uninitialized field ref when borrowing (#10466)
fixes #10455 

@KAAtheWiseGit, I'm sorry, I didn't mean to block your first PR #10461,
didn't see you had submitted it till I got around to submitting this. If
you want to incoporate useful ideas from this PR into yours, I do not
mind deferring to you.


# Description
Changes made in `datetime-diff`:
* Initialize millisecond and microsecond fields in `$current`, to fix
the error when borrow needs to refer to them.
* Fix `borrow_nanoseconds` to borrow from seconds, not from (unused)
microseconds.
* Added error check to insist that first argument is >= second argument.
`datetime-diff` doesn't represent negative durations correctly (it tries
to borrow out of the year, resulting in negative year and positive all
other fields). We don't currently have a use case requiring negative
durations.
* Add comments so help is a bit clearer (I was surprised that the first
argument, named `$from` was actually supposed to be the *later*
datetime. The order of arguments is reasonable (reminiscent of <later>
<minus> <earlier>), so I just changed the param name to match its
purpose.

Changes made in `pretty-print-duration`:
* changed type of argument from `duration` to `record`. (it's not clear
why Nu was not complaining about this!)
* changed test for skipping a clause from `> 0` to `!= 0`. Even though
`datetime-diff` won't present a negative field in the record, user might
call `pretty-print-duration` with one, might as well handle it. (but I
think `hour:-2` will be rendered as `-2hr`, not `-2hrs`...).
* added help and an example.

# User-Facing Changes
none requiring code changes.

differentiating between --x and --x: bool (#10456)
# Description
Fixes: #10450 

This pr differentiating between `--x: bool` and `--x`

Here are examples which demostrate difference between them:
```nushell
def a [--x: bool] { $x };
a --x    # not allowed, you need to parse a value to the flag.
a        # it's allowed, and the value of `$x` is false, which behaves the same to `def a [--x] { $x }; a`
```

For boolean flag with default value, it works a little bit different to
#10450 mentioned:
```nushell
def foo [--option: bool = false] { $option }
foo                  # output false
foo --option         # not allowed, you need to parse a value to the flag.
foo --option true    # output true
```

# User-Facing Changes
After the pr, the following code is not allowed:
```nushell
def a [--x: bool] { $x }; a --x
```

Instead, you have to pass a value to flag `--x` like `a --x false`. But
bare flag works in the same way as before.

## Update: one more breaking change to help on #7260 
```
def foo [--option: bool] { $option == null }
foo
```
After the pr, if we don't use a boolean flag, the value will be `null`
instead of `true`. Because here `--option: bool` is treated as a flag
rather than a switch

Update internal use of decimal to float (#10333)
# Description
We made the decision that our floating point type should be referred to
as `float` over `decimal`.
Commands were updated by #9979 and #10320

Now make the internal codebase consistent in referring to this data type
as `float`.

Work for #10332

# User-Facing Changes

`decimal` has been removed as a type name/symbol. 

Instead of 
```nushell
def foo [bar: decimal] decimal -> decimal {}
```
use 
```nushell
def foo [bar: float] float -> float {}
```

Potential effect of `SyntaxShape`'s `Display` implementation now also
referring to `float` instead of `decimal`

# Details
- Rename `SyntaxShape::Decimal` to `Float`
- Update `Display for SyntaxShape` to `float`
- Update error message + fn name in dataframe code
- Fix docs in command examples
- Rename tests that are float specific

Remove python-like string multiplication (#10293)
# Description
Currently we support "multiplication" of strings, resulting in a terse
way to repeat a particular string.
This can have unintended side effects when dealing with mixed data (e.g.
after parsing data that is not all numbers).
Furthermore as we frequently fall-back to strings while parsing source
code, this introduced a runaway edge case in const evaluation (#10212)

Work for #10233

## Details
- Remove python-like string multiplication.
- Workaround for indentation
  - This should probably be addressed with a purpose built command
- Remove special const-eval error test

# User-Facing Changes
**Major breaking change!**
`"string" * 42` will stop working. (This was used for example in the
stdlib)

We should bless a good alternative before landing this

Rename into decimal to into float (#9979)
# Description
We keep "into decimal" for a release and warn through a message that it
will be removed in 0.86.

All tests are updated to use `into float`

# User-Facing Changes
`into decimal` raises a deprecation warning, will be removed soon.
Use `into float` as the new functionally identical command instead.

```
~/nushell> 2 | into decimal
Error:   × Deprecated command
   ╭─[entry #1:1:1]
 1 │ 2 | into decimal
   ·     ──────┬─────
   ·           ╰── `into decimal` is deprecated and will be removed in 0.86.
   ╰────
  help: Use `into float` instead

Users can use functions like "from ndjson" in standard library, and can
open ndjson files with `open` command.
```
use std formats *
# `from ndjson` is available now
open sample.ndjson
```

change LOG_FORMAT to NU_LOG_FORMAT in nu-std library (#10254)
this closes #10248 

@fdncred pointed out the problem and he was correct 😄 

I went ahead and made the simple change and the
https://github.com/influxdata/influxdb_iox binary
works like a charm...

@amtoine hopefully there are no issues with this change

I believe its a good one as other rust binaries might take advantage of
this common
environment variable as well...

move math constants to standard library (#9678)
# Description
we talked about this before in some meetings so i thought, why not?

the hope is that these constants do not require Rust code to be
implemented and that this move will make the Rust source base a bit
smaller 🤞

# User-Facing Changes
mathematical constants (e, pi, tau, phi and gamma) are now in `std math`
rather than `math`

## what can be done
```nushell
> use std; $std.math
> use std math; $math
> use std *; $math
```
will all give
```
╭───────┬────────────────────╮
│ GAMMA │ 0.5772156649015329 │
│ E     │ 2.718281828459045  │
│ PI    │ 3.141592653589793  │
│ TAU   │ 6.283185307179586  │
│ PHI   │ 1.618033988749895  │
╰───────┴────────────────────╯
```
and the following will work too
```nushell
> use std math E; $E
2.718281828459045
```
```nushell
> use std math *; $GAMMA
0.5772156649015329
```

## what can NOT be done
looks like every export works fine now 😌
