# Description
<!--
Thank you for improving Nushell. Please, check our [contributing
guide](../CONTRIBUTING.md) and talk to the core team before making major
changes.

Description of your pull request goes here. **Provide examples and/or
screenshots** if your changes affect the user experience.
-->

Related to #11693. It looks like there is no reason for Nu shell's
`clear` to behave differently than other shells' `clear`. To improve the
UX and fulfill the user expectations, the default has been adjusted to
work the same as in other shells by clearing the scrollback buffer. For
edge cases where someone depends on the current behavior of keeping the
scrollback, a `-k` option has been added.

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

- Improve the UX of `clear` by changing the default behavior to the same
as other popular shells, i.e clear scrollback by default.
- Remove `-a --all` flag, make it the default behavior to clear the
scrollback
- Add `-k --keep-scrollback` flag for backward compat to keep the
scrollback buffer

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` to run the
tests for the standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```
-->

This is a simple change flipping the flag and default behavior, no tests
should be needed.

# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.

fix path exists on a non-directory file (#13763)
# Description
Fixes:  #13460

The issue is caused by `try_exists` method on path, it will return
`Err(NotADirectory)` if user tried to check for a path under a regular
file.
To fix it, I think it's ok to use `exists` rather than `try_exists`,
although
[Path::exists()](https://doc.rust-lang.org/std/path/struct.Path.html#method.exists)
only checks whether or not a path was both found and readable. I think
it's ok, and we can add this information under `extra_description`.

# User-Facing Changes
The following code will no longer raise error:
```
touch a; 'a/b' | path exists
```

# Tests + Formatting
Added 1 test.

add metadata access command (#13785)
# Description
Add `metadata access`, which allows accessing/inspecting the metadata of
a stream in a closure.
```nu
ls | metadata access {|meta|
    ...
}
```

- The metadata is provided as an argument to the closure, identical to
the record obtained with `metadata` command.

- `metadata access` passes its input stream into the closure as it is.

- Within the closure, both the metadata and the stream are available.
The closure may modify, collect or pass the stream as it is.

# Motivation
- Without this command, nu code can't act on metadata without losing the
stream, use cases requiring both the stream and metadata must be
implemented either as a built-in or a plugin.

- This command allows users to enhance presentation of data, similar to
`table` coloring the output of `ls`.

Fix IR for try (#13811)
# Description
Fixes a bug in the IR for `try` to match that of the regular evaluator
(continuing from #13515):
```nushell
# without IR:
try { ^false } catch { 'caught' } # == 'caught'

# with IR:
try { ^false } catch { 'caught' } # error, non-zero exit code
```

In this PR, both now evaluate to `caught`. For the implementation, I had
to add another instruction, and feel free to suggest better
alternatives. In the future, it might be possible to get rid of this
extra instruction.

# User-Facing Changes
Bug fix, `try { ^false } catch { 'caught' }` now works in IR.

Error on non-zero exit statuses (#13515)
# Description
This PR makes it so that non-zero exit codes and termination by signal
are treated as a normal `ShellError`. Currently, these are silent
errors. That is, if an external command fails, then it's code block is
aborted, but the parent block can sometimes continue execution. E.g.,
see #8569 and this example:
```nushell
[1 2] | each { ^false }
```

Before this would give:
```
╭───┬──╮
│ 0 │  │
│ 1 │  │
╰───┴──╯
```

Now, this shows an error:
```
Error: nu:🐚:eval_block_with_input

  × Eval block failed with pipeline input
   ╭─[entry #1:1:2]
 1 │ [1 2] | each { ^false }
   ·  ┬
   ·  ╰── source value
   ╰────

Error: nu:🐚:non_zero_exit_code

  × External command had a non-zero exit code
   ╭─[entry #1:1:17]
 1 │ [1 2] | each { ^false }
   ·                 ──┬──
   ·                   ╰── exited with code 1
   ╰────
```

This PR fixes #12874, fixes #5960, fixes #10856, and fixes #5347. This
PR also partially addresses #10633 and #10624 (only the last command of
a pipeline is currently checked). It looks like #8569 is already fixed,
but this PR will make sure it is definitely fixed (fixes #8569).

# User-Facing Changes
- Non-zero exit codes and termination by signal now cause an error to be
thrown.
- The error record value passed to a `catch` block may now have an
`exit_code` column containing the integer exit code if the error was due
to an external command.
- Adds new config values, `display_errors.exit_code` and
`display_errors.termination_signal`, which determine whether an error
message should be printed in the respective error cases. For
non-interactive sessions, these are set to `true`, and for interactive
sessions `display_errors.exit_code` is false (via the default config).

# Tests
Added a few tests.

# After Submitting
- Update docs and book.
- Future work:
- Error if other external commands besides the last in a pipeline exit
with a non-zero exit code. Then, deprecate `do -c` since this will be
the default behavior everywhere.
- Add a better mechanism for exit codes and deprecate
`$env.LAST_EXIT_CODE` (it's buggy).

Use String::contains instead of exact match when matching content types for http requests. (#13791)
# Description
The existing code uses exact matches on content type. This can caused
things like "application/json; charset=utf-8" that contain a charset not
using send_json method.

NOTE: The charset portion in the above example would still be ignored as
we rely on serde and the client library to control the encoding, it is
still better to catch the json case.

Don't panic on detect columns with --guess flag (#13752)
# Description
This pr addresses the comment:
https://github.com/nushell/nushell/issues/11791#issuecomment-2308384155

It's caused by if the last row have a very different format to the first
row, the value of `end_char` will exceed the `line_char_boundaries`.
Adding a guard for it should avoid such panic.

# User-Facing Changes
The following code should no longer panic:
```shell
"nu_plugin_highlight = '1.2.2+0.97.1'    # A nushell plugin for syntax highlighting
trace_nu_plugin = '0.3.1'               # A wrapper to trace Nu plugins
nu_plugin_bash_env = '0.13.0'           # Nu plugin bash-env
nu_plugin_from_sse = '0.4.0'            # Nushell plugin to convert a HTTP server sent event stream to structured data
... and 90 crates more (use --limit N to see more)" | detect columns -n --guess

Make tee work more nicely with non-collections (#13652)
# Description

This changes the behavior of `tee` to be more transparent when given a
value that isn't a list or range. Previously, anything that wasn't a
byte stream would converted to a list stream using the iterator
implementation, which led to some surprising results. Instead, now, if
the value is a string or binary, it will be treated the same way a byte
stream is, and the output of `tee` is a byte stream instead of the
original value. This is done so that we can synchronize with the other
thread on collect, and potentially capture any error produced by the
closure.

For values that can't be converted to streams, the closure is just run
with a clone of the value instead on another thread. Because we can't
wait for the other thread, there is no way to send an error back to the
original thread, so instead it's just written to stderr using
`report_error_new()`.

There are a couple of follow up edge cases I see where byte streams
aren't necessarily treated exactly the same way strings are, but this
should mostly be a good experience.

Fixes #13489.

# User-Facing Changes

Breaking change.

- `tee` now outputs and sends string/binary stream for string/binary
input.
- `tee` now outputs and sends the original value for any other input
other than lists/ranges.

# Tests + Formatting

Added for new behavior.

Setup global cargo lint configuration (#13691)
# Description
`cargo` somewhat recently gained the capability to store `lints`
settings for the crate and workspace, that can override the defaults
from `rustc` and `clippy` lints. This means we can enforce some lints
without having to actively pass them to clippy via `cargo clippy -- -W
...`. So users just forking the repo have an easier time to follow
similar requirements like our CI.

## Limitation

An exception that remains is that those lints apply to both the primary
code base and the tests. Thus we can't include e.g. `unwrap_used`
without generating noise in the tests. Here the setup in the CI remains
the most helpful.

## Included lints

- Add `clippy::unchecked_duration_subtraction` (added by #12549)
# User-Facing Changes
Running `cargo clippy --workspace` should be closer to the CI. This has
benefits for editor configured runs of clippy and saves you from having
to use `toolkit` to be close to CI in more cases.

Remove str deunicode (#13693)
# Description
Closes #13677

Remove the command `str deunicode`, as it has a narrow application, is
loosely defined by the data provided by the `deunicode` crate and thus a
stabilization liability post-1.0.

Furthermore the data to perform the look-up is quite substantial.

Removing the command and the `deunicode` dependency saves 0.9 MB of
binary data in release mode (~ 2% of total)

(checked via `cargo bloat --release` for a linux x86 build)

encode/decode for multiple alphabets (#13428)
Based on the discussion in #13419.


## Description

Reworks the `decode`/`encode` commands by adding/changing the following
bases:

- `base32`
- `base32hex`
- `hex`
- `new-base64`

The `hex` base is compatible with the previous version of `hex` out of
the box (it only adds more flags). `base64` isn't, so the PR adds a new
version and deprecates the old one.

All commands have `string -> binary` signature for decoding and `string
| binary -> string` signature for encoding. A few `base64` encodings,
which are not a part of the
[RFC4648](https://datatracker.ietf.org/doc/html/rfc4648#section-6), have
been dropped.


## Example usage

```Nushell
~/fork/nushell> "string" | encode base32 | decode base32 | decode
string
```

```Nushell
~/fork/nushell> "ORSXG5A=" | decode base32
# `decode` always returns a binary value
Length: 4 (0x4) bytes | printable whitespace ascii_other non_ascii
00000000:   74 65 73 74                                          test
```


## User-Facing Changes

- New commands: `encode/decode base32/base32hex`.
- `encode hex` gets a `--lower` flag.
- `encode/decode base64` deprecated in favor of `encode/decode
new-base64`.

Change the usage misnomer to "description" (#13598)
# Description
    
The meaning of the word usage is specific to describing how a command
function is *used* and not a synonym for general description. Usage can
be used to describe the SYNOPSIS or EXAMPLES sections of a man page
where the permitted argument combinations are shown or example *uses*
are given.
Let's not confuse people and call it what it is a description.

Our `help` command already creates its own *Usage* section based on the
available arguments and doesn't refer to the description with usage.

Change behavior of into record on lists to be more useful (#13637)
# Description

The previous behaviour of `into record` on lists was to create a new
record with each list index as the key. This was not very useful for
creating meaningful records, though, and most people would end up using
commands like `headers` or `transpose` to turn a list of keys and values
into a record.

This PR changes that instead to do what I think the most ergonomic thing
is, and instead:

- A list of records is merged into one record.
- A list of pairs (two element lists) is folded into a record with the
first element of each pair being the key, and the second being the
value.

The former is just generally more useful than having to use `reduce`
with `merge` for such a common operation, and the latter is useful
because it means that `$a | zip $b | into record` *just works* in the
way that seems most obvious.

Example:

```nushell
[[foo bar] [baz quux]] | into record # => {foo: bar, baz: quux}
[{foo: bar} {baz: quux}] | into record # => {foo: bar, baz: quux}
[foo baz] | zip [bar quux] | into record # => {foo: bar, baz: quux}
```

The support for range input has been removed, as it would no longer
reflect the treatment of an equivalent list.

The following is equivalent to the old behavior, in case that's desired:

```
0.. | zip [a b c] | into record # => {0: a, 1: b, 2: c}
```

# User-Facing Changes
- `into record` changed as described above (breaking)
- `into record` no longer supports range input (breaking)

# Tests + Formatting
Examples changed to match, everything works. Some usage in stdlib and
`nu_plugin_nu_example` had to be changed.

Fallback to extension-based content type detection when parsing Content-Type header fails (#13610)
# Description

Previously when nushell failed to parse the content type header, it
would emit an error instead of returning the response. Now it will fall
back to `text/plain` (which, in turn, will trigger type detection based
on file extension).

May fix (potentially) nushell/nushell#11927

Supercedes: #13609 

# User-Facing Changes

It's now possible to fetch content even if the server returns an invalid
content type header. Users may need to parse the response manually, but
it's still better than not getting the response at all.

# Tests + Formatting

Added a test for the new behaviour.

create a better error message for bad glob patterns (#13613)
# Description

@sholderbach pointed out that I could've made this error message better.
So, here's my attempt to make it better.

This should work. I had a hard time figuring out how to trigger the
error anyway because the type checker doesn't allow "bad" parameters to
begin with.

add more helpful error with text/xml (#13609)
# Description

This PR is meant to provide a more helpful error message when using http
get and the content type can't be parsed.

The span isn't perfect but there's no way to get the span of the content
type that I can see.

In the middle of fixing this error, I also discovered how to fix the
problem in general. Since you can now see the error message complaining
about double quotes (char 22 at position 0. 22 hex is `"`). The fix is
just to remove all the double quotes from the content_type and then you
get this.

### After After

![image](https://github.com/user-attachments/assets/2223d34f-4563-4dea-90eb-83326e808af1)

The discussion on Discord about this is that `--raw` or
`--ignore-errors` should eat this error and it "just work" as well as
default to text or binary when the mime parsing fails. I agree but this
PR does not implement that.

Make error-message more helpful when user invokes a non-executable file (#13589)
# Description

Fixes Issue #13477 
This adds a check to see if a user is trying to invoke a
(non-executable) file as a command and returns a helpful error if so.
EDIT: this will not work on Windows, and is arguably not relevant there,
because of the different semantics of executables. I think the
equivalent on Windows would be if a user tries to invoke `./foo`, we
should look for `foo.exe` or `foo.bat` in the directory and recommend
that if it exists.

# User-Facing Changes

When a user invokes an unrecognized command that is the path to an
existing file, the error used to say:
`{name} is neither a Nushell built-in or a known external command` 
This PR proposes to change the message to:
`{name} refers to a file that is not executable. Did you forget to to
set execute permissions?`

# Tests + Formatting
Ran cargo fmt, clippy and test on the workspace. 
EDIT: added test asserting the new behavior

Add --raw switch to print for binary data (#13597)
# Description

Something I meant to add a long time ago. We currently don't have a
convenient way to print raw binary data intentionally. You can pipe it
through `cat` to turn it into an unknown stream, or write it to a file
and read it again, but we can't really just e.g. generate msgpack and
write it to stdout without this. For example:

```nushell
[abc def] | to msgpack | print --raw
```

This is useful for nushell scripts that will be piped into something
else. It also means that `nu_plugin_nu_example` probably doesn't need to
do this anymore, but I haven't adjusted it yet:

```nushell
def tell_nushell_encoding [] {
  print -n "\u{0004}json"
}
```

This happens to work because 0x04 is a valid UTF-8 character, but it
wouldn't be possible if it were something above 0x80.

`--raw` also formats other things without `table`, I figured the two
things kind of go together. The output is kind of like `to text`.
Debatable whether that should share the same flag, but it was easier
that way and seemed reasonable.

# User-Facing Changes
- `print` new flag: `--raw`

Make the math commands const (#13566)
This PR closes [Issue
#13482](https://github.com/nushell/nushell/issues/13482)

# Description
This PR tend to make all math function to be constant. 

# User-Facing Changes
The math commands now can be used as constant methods.

### Some Example
```
> const MODE = [3 3 9 12 12 15] | math mode
> $MODE
╭───┬────╮
│ 0 │  3 │
│ 1 │ 12 │
╰───┴────╯

> const LOG = [16 8 4] | math log 2
> $LOG
╭───┬──────╮
│ 0 │ 4.00 │
│ 1 │ 3.00 │
│ 2 │ 2.00 │
╰───┴──────╯

> const VAR = [1 3 5] | math variance
> $VAR
2.6666666666666665
```

# Tests + Formatting
Tests are added for all of the math command to test there constant
behavior.

I mostly focused on the actual user experience, not the correctness of
the methods and algorithms.

# After Submitting
I think this change don't require any additional documentation. Feel
free to correct me in this topic please.

# User-Facing Changes
`http post --content-type multipart/form-data` now accepts a record
which is uploaded as `multipart/form-data`.
Binary data is uploaded as files (`application/octet-stream`),
everything else is uploaded as plain text.

Previously `http post --content-type multipart/form-data` rejected
records, so there's no BC break.

Allow int input when using a formatstring in into datetime (#13541)
# Description

When using a format string, `into datetime` would disallow an `int` even
when it logically made sense. This was mainly a problem when attempting
to convert a Unix epoch to Nushell `datetime`. Unix epochs are often
stored or returned as `int` in external data sources.

```nu
1722821463 | into datetime -f '%s'
Error: nu:🐚:only_supports_this_input_type

  × Input type not supported.
   ╭─[entry #3:1:1]

   · ─────┬────   ──────┬──────
   ·      │             ╰── only string input data is supported
   ·      ╰── input type: int
   ╰────
```

While the solution was simply to `| to text` the `int`, this PR handles
the use-case automatically.

Essentially a ~5 line change that just moves the current parsing to a
closure that is called for both Strings and Ints-converted-to-Strings.

Clarify random int help (#13503)
# Description

Minor nitpicks, but the `random int` help and examples were a bit
ambiguous in several aspects. Updated to clarify that:

* An unconstrained `random int` returns a non-negative integer. That is,
the smallest potential value is 0. Technically integers include negative
numbers as well, and `random int` will never return one unless you pass
it a range with a negative lower-bound.

* To that end, changed the final example to demonstrate a negative
lower-bound.

* The range is inclusive. While most people would probably assume this,
the changes make this explicit in the examples and argument description.

https://github.com/rust-lang/rust-clippy/issues/13188 as the nightly
`byte_char_slices` would require either a global allow or otherwise a
ton of granular allows or possibly confusing bytestring literals.

save: print to stderr for bytestream (#13422)
# Description
Fixes: #13260 

When user run a command like this:

$env.BAZ = " New Err";
do -i {nu -n -c 'nu --testbin echo_env FOO; nu --testbin echo_env_stderr BAZ'} | save -a -r save_test_22/log.txt
```

`save` command sinks the output of previous commands' stderr output. I
think it should be `stderr`.

# User-Facing Changes

Make assignment and const consistent with let/mut (#13385)
# Description

This makes assignment operations and `const` behave the same way `let`
and `mut` do, absorbing the rest of the pipeline.

Changes the lexer to be able to recognize assignment operators as a
separate token, and then makes the lite parser continue to push spans
into the same command regardless of any redirections or pipes if an
assignment operator is encountered. Because the pipeline is no longer
split up by the lite parser at this point, it's trivial to just parse
the right hand side as if it were a subexpression not contained within
parentheses.

# User-Facing Changes
Big breaking change. These are all now possible:

```nushell
const path = 'a' | path join 'b'

mut x = 2
$x = random int
$x = [1 2 3] | math sum

$env.FOO = random chars
```

In the past, these would have led to (an attempt at) bare word string
parsing. So while `$env.FOO = bar` would have previously set the
environment variable `FOO` to the string `"bar"`, it now tries to run
the command named `bar`, hence the major breaking change.

However, this is desirable because it is very consistent - if you see
the `=`, you can just assume it absorbs everything else to the right of
it.

# Tests + Formatting
Added tests for the new behaviour. Adjusted some existing tests that
depended on the right hand side of assignments being parsed as
barewords.

don't force stripping ansi codes from strings in stor (#13464)
# Description

The current version of `stor` forces stripping ansi code coloring from
all the strings.
In this PR, I propose to keep strings unchanged.

The logic behind the proposed changes was best described in the
[discord](https://discord.com/channels/601130461678272522/601130461678272524/1266387441074442272):
<img width="773" alt="image"
src="https://github.com/user-attachments/assets/063cdebd-684f-46f1-aca1-faeb4827723d">

with proposed changes we can store colored output:
```
stor reset; stor create --table-name test --columns {a: str};
ls | table | {a: $in} | stor insert --table-name test | null;
stor open | query db 'select a from test' | get a.0 
```

<img width="704" alt="image"
src="https://github.com/user-attachments/assets/8f062808-18fc-498b-a77e-a118f6b9953a">


# User-Facing Changes

If one was using `stor` together with ansi colored input, and then was
querying `stor` with search operations, they might break. But I don't
think that it is a big problem, as one will just need to use `ansi
reset` before storing data.

Tests are okay.

Fix output format borken in char --list (#13417)
# Description

Resolve #13395 

When we use the `char --list` command, it also outputs the characters
*bel* and *backspace*, which breaks the table's alignment.

16-10-03](https://github.com/user-attachments/assets/54561cbc-f1a1-4ccd-9561-65dccc939280)
I also found that the behaviour at the beginning of the table is not
correct because of some line change characters, as I mentioned in the
issue discussion.

So, the solution is to create a list containing the characters that do
not need to be output. When the name is in the list, we output the
character as an empty string. Here is the behaviour after fixing.

generate: switch the position of <initial> and <closure>, so the closure can have default parameters (#13393)
# Description
Close: #12083 
Close: #12084 

# 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
   ╭─[entry #5:1:1]

Overhaul $in expressions (#13357)
# 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

Remove default list-diving behaviour (#13386)
# 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.

Deprecate group in favor of chunks (#13377)
# 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.

Fix select cell path renaming behavior (#13361)
# 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.

Add IR support to the debugger (#13345)
# 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.

All passing.

Fix order of I/O types in take until (#13356)
# 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>
}

Update config directly at assignment (#13332)
# 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.

Add more argument types to view ir (#13343)
# 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.

Internal representation (IR) compiler and evaluator (#13330)
# 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

   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

  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
  }
  $b
}
use std bench
bench { 0..50 | each { |n| fib $n } }

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`

Add and use new Signals struct (#13314)
# 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.

Fix from toml to handle toml datetime correctly (#13315)
# 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.

```
~/Development/nushell> "dob = 2023-05-27" | from toml
╭─────┬────────────╮
│ dob │ a year ago │
╰─────┴────────────╯
~/Development/nushell> "dob = 2023-05-27" | from toml |
Sat, 27 May 2023 00:00:00 +0000 (a year ago)
~/Development/nushell>                            
```

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

```
~/Development/nushell> "tm = 11:00:00" | from toml
╭────┬──────────╮
│ tm │ 11:00:00 │
╰────┴──────────╯
~/Development/nushell> "tm = 11:00:00" | from toml | get tm
11:00:00
~/Development/nushell>  
```

# Tests + Formatting

When I ran tests, `commands::touch::change_file_mtime_to_reference`
failed with the following error.
The error also occurs in the master branch, so it's probably unrelated
to these changes.
(maybe a problem with my dev environment)

Preserve attributes on external ByteStreams (#13305)
# 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
```

# Tests + Formatting
Added a test to cover this to `into binary`

Use pipeline data for http post|put|patch|delete commands. (#13254)
# 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.

Skip decoration lines for detect columns --guess (#13274)
# 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`:

![image](https://github.com/nushell/nushell/assets/20356389/06c873fb-0a26-45dd-b020-3bcc737d027f)

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

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.

# Tests + Formatting
Added tests that exercise these edge cases, as well as a single-column
test to make sure that trivial cases keep working.

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

--guess`, since winget sometimes uses the unicode ellipsis symbol (`…`)

Make the subcommands (from {csv, tsv, ssv}) 0-based for consistency (#13209)
# Description

fixed #11678

The sub-commands of from command (`from {csv, tsv, ssv}`) name columns
starting from index 0.
This behaviour is inconsistent with other commands such as `detect
columns`.
This PR makes the subcommands index 0-based.

# User-Facing Changes

starting at index 0 if no header data is passed.

Mitigate the poor interaction between ndots expansion and non-path strings (#13218)
# 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

Suppress column index for default cal output (#13188)
# 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.

Fixed generate command signature (#13200)
# 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.

Move most of the peculiar argument handling for external calls into the parser (#13089)
# 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.

Table help rendering (#13182)
# 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.

# User-Facing Changes

Change the error style during tests to plain (#13061)
# Description

This fixes issues with trying to run the tests with a terminal that is
small enough to cause errors to wrap around, or in cases where the test
environment might produce strings that are reasonably expected to wrap
around anyway. "Fancy" errors are too fancy for tests to work
predictably 😉

cc @abusch

# User-Facing Changes

- Added `--error-style` option for use with `--commands` (like
`--table-mode`)

# Tests + Formatting

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.

Improves commands that support range input (#13113)
# Description
Fixes: #13105
Fixes: #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.

### Before
```nushell
# str substring
❯ ("aaa" | str substring 2..-3) == ""
Error: nu:🐚:type_mismatch

  × Type mismatch.
   ╭─[entry #23:1:10]
 1 │ ("aaa" | str substring 2..-3) == ""
   ·          ──────┬──────
   ·                ╰── End must be greater than or equal to Start
 2 │ true
   ╰────

# bytes at
❯ ("aaa" | encode utf-8 | bytes at 2..-3) == ("" | encode utf-8)
Error: nu:🐚:type_mismatch

  × Type mismatch.
   ╭─[entry #27:1:25]
 1 │ ("aaa" | encode utf-8 | bytes at 2..-3) == ("" | encode utf-8)
   ·                         ────┬───
   ·                             ╰── End must be greater than or equal to Start
   ╰────
```
### After
```nushell
# str substring
❯ ("aaa" | str substring 2..-3) == ""
true

# bytes at
❯  ("aaa" | encode utf-8 | bytes at 2..-3) == ("" | encode utf-8)

Add derive macros for FromValue and IntoValue to ease the use of Values in Rust code (#13031)
# 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.

Make which-support feature non-optional (#13125)
# 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.

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.

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)"`.

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:

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.

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.

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",
]
```

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.

# Tests + Formatting
No additional tests here... but that might be a good idea.

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.
