# Description
The `kill` command returns a stream with a single value. This PR changes
it to simply return the value.
# User-Facing Changes
Technically a breaking change.
# Description
Refactors `drop` using `Vec::truncate` and adds a `NeedsPositiveValue`
error.
# User-Facing Changes
Breaking change: `drop` now errors if the number of rows/columns is
negative.
# Description
This PR just adds better logging for shell_integration and tweaks the
ansi escapes so they're closer to where the action happens. I also added
some perf log entries to help better understand plugin file load and
eval performance.

# Description
`polars ls` is already different that `dfr ls`. Currently it just shows
the cache key, columns, rows, and type. I have added:
- creation time
- size
- span contents
- span start and end

# Description
The CI has been failing lately on macOS, most likely because it's
running out of memory now that
the `polars` plugin has been included and it's quite large on top of
`dfr`.
This PR just makes use use the `macos-13` runner instead of
`macos-latest` because the latter has
only half as much RAM because it's running on the Apple M1 platform.

# Description
while i'm 100% okey with the original intent behind
https://github.com/nushell/nushell/pull/12196, i think the PR did
introduce two unintended things:
- extra parentheses that make the `log.nu` module look like Lisp lol
- a renaming of the `NU_LOG_LEVEL` environment variable to
`NU_log-level`. this breaks previous usage of `std log` and, as it's not
mentionned at all in the PR, i thought it was not intentional 😋
# User-Facing Changes
users can now control `std log` with `$env.NU_LOG_LEVEL`
# Tests + Formatting
the "log" tests have been fixed as well.

# Description
This is an attempt to isolate the unit tests from whatever might be in
the user's config. If the
user's config is broken in some way or incompatible with this version
(for example, especially if
there are plugins that aren't built for this version), tests can
spuriously fail.
This makes tests more reliably pass the same way they would on CI even
if the user has config, and
should also make them run faster.
I think this is _good enough_, but I still think we should have a
specific config dir env variable for nushell specifically (rather than
having to use `XDG_CONFIG_HOME`, which would mess with other things) and
then we can just have `nu-test-support` set that to a temporary dir
containing the shipped default config files.

# Description
I spent a while trying to come up with a good name for what is currently
`IoStream`. Looking back, this name is not the best, because it:
1. Implies that it is a stream, when it all it really does is specify
the output destination for a stream/pipeline.
2. Implies that it handles input and output, when it really only handles
output.
So, this PR renames `IoStream` to `OutDest` instead, which should be
more clear.

# Description
I have `nu` set as my shell in my editor, which allows me to easily pipe
selections of text to things like `str pascal-case` or even more complex
string operation pipelines, which I find super handy. However, the only
annoying thing is that I pretty much always have to add `| print -n` at
the end, because `nu` adds a newline when it prints the resulting value.
This adds a `--no-newline` option to stop that from happening, and then
you don't need to pipe to `print -n` anymore, you can just have your
shell command for your editor contain that flag.
# User-Facing Changes

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

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

# Description
This decouples the serialized representation of `Record` from its
internal implementation. It now gets treated as a map type in `serde`.
This has several benefits:
- more efficient representation (not showing inner fields)
- human readable e.g. as a JSON record
- no breaking changes when refactoring the `Record` internals in the
future (see #12326, or potential introduction of `indexmap::IndexMap`
for large N)
- we now deny the creation of invalid records a non-cooperating plugin
could produce
- guaranteed key-value correspondence
- checking for unique keys
# Breaking change to the plugin protocol:
Now expects a record/map directly as the `Record.val` field instead of a
serialization of it.

Fixes a problem introduced in
https://github.com/nushell/nushell/pull/12420 where one of the config
path tests (`test_xdg_config_symlink`) fails if, on MacOS, a developer
already has config files in the default location for that platform.
This happened because the test is making sure the
`xdg_config_home_invalid` error isn't reported, but to do that, it
asserts that stderr is empty, which it is not if in the case mentioned
above, because Nushell warns that the default location
(`~/.config`/`~/Library/Application Support`) is not empty but
`XDG_CONFIG_HOME` is empty.
If someone with a Mac could test this, that'd be great.

Fixes#12416. Turns out that in src/main.rs, `XDG_CONFIG_HOME` wasn't

rectified now.

I manually tested it and the error has disappeared:
New behavior (this branch):
Old behavior (main):
Thanks to a pointer from Devyn, I've now added tests to make sure the
`xdg_config_home_invalid` error doesn't pop up when `XDG_CONFIG_HOME` is
a symlink (and does when it's actually invalid).
Turns out two of the tests in `test_config_path` tried modifying
`XDG_CONFIG_HOME` using `playground.with_env` but used `nu!`, so the
subprocess didn't actually use the modified value of `XDG_CONFIG_HOME`.
When I added them, I was unaware that the `.with_env` didn't actually
modify the environment. This has now been rectified.

# Description
Some of the tests in `tests::shell` were using `sh` unnecessarily, and
had `#[cfg(not(windows))]` when they should be testable on Windows if
`sh` is not used.
I also found that they were using `.expect()` incorrectly, under the
assumption that that would check their output, when really an
`assert_eq!` on the output is needed to do that. So these tests weren't
even really working properly before.

This speeds up writing messages to the plugin, because otherwise every
individual piece of the messages (not even the entire message) is
written with one syscall, leading to a lot of back and forth with the
kernel.
I learned this by running `strace` to debug something and saw a ton of
`write()` calls.

# Description
Requested by @ayax79. This makes the custom value behavior more correct,
by calling the methods on the plugin to handle the custom values in
examples rather than the methods on the custom values themselves. This
helps for handle-type custom values (like what he's doing with
dataframes).
- Equality checking in `PluginTest::test_examples()` changed to use
`PluginInterface::custom_value_partial_cmp()`
- Base value rendering for `PluginSignature` changed to use
`Plugin::custom_value_to_base_value()`
- Had to be moved closer to `serve_plugin` for this reason, so the test
for writing signatures containing custom values was removed
- That behavior should still be tested to some degree, since if custom
values are not handled, signatures will fail to parse, so all of the
other tests won't work.
# User-Facing Changes
- `Record::sort_cols()` method added to share functionality required by
`PartialCmp`, and it might also be slightly faster
- Otherwise, everything should mostly be the same but better. Plugins
that don't implement special handling for custom values will still work
the same way, because the default implementation is just a pass-through
to the `CustomValue` methods.

# Description
Because the plugin interface reader thread can be responsible for
sending a drop notification, it's possible for it to end up in a
deadlock where it's waiting for the response to the drop notification
call.
I decided that the best way to address this is to just discard the
response and not wait for it. It's not really important to synchronize
with the response to `Dropped`, so this is probably faster anyway.
cc @ayax79, this is your issue where polars is getting stuck
# User-Facing Changes
- A bug fix
- Custom value plugin: `custom-value handle update` command
# Tests + Formatting
Tried to add a test with a long pipeline with a lot of drops and run it
over and over to reproduce the deadlock.
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`
Encountered repeated build failure that vanished after clearing the
existing build caches.
- Don't `fail-fast` (this is highly annoying, if a severe problem is
detected, there is still the possibility to intervene manually)
- Don't cache the build process, we do it rarely so any potential
speed-up is offset by the uncertainty if this affects the artefact
fixes#12361
Looking at the condition, `TRASH_SUPPORTED && (trash || (rm_always_trash
&& !permanent))`, this code path seems only to run when `--trash` is
enabled and `--permanent` is disabled.
This suggests that the `--trash` suggestion is a mistake and should have
suggested `--permanent`.

- shows type signatures
# 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 std testing; testing run-tests --path
crates/nu-std"` 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
