This PR:
1. Adds basic support for `CustomValue` to `explore`. Previously `open
foo.db | explore` didn't really work, now we "materialize" the whole
database to a `Value` before loading it
2. Adopts `anyhow` for error handling in `explore`. Previously we were
kind of rolling our own version of `anyhow` by shoving all errors into a
`std::io::Error`; I think this is much nicer. This was necessary because
as part of 1), collecting input is now fallible...
3. Removes a lot of `explore`'s fancy command help system.
- Previously each command (`:help`, `:try`, etc.) had a sophisticated
help system with examples etc... but this was not very visible to users.
You had to know to run `:help :try` or view a list of commands with
`:help :`
- As discussed previously, we eventually want to move to a less modal
approach for `explore`, without the Vim-like commands. And so I don't
think it's worth keeping this command help system around (it's
intertwined with other stuff, and making these changes would have been
harder if keeping it).
4. Rename the `--reverse` flag to `--tail`. The flag scrolls to the end
of the data, which IMO is described better by "tail"
5. Does some renaming+commenting to clear up things I found difficult to
understand when navigating the `explore` code
I initially thought 1) would be just a few lines, and then this PR blew
up into much more extensive changes 😅
## Before
The whole database was being displayed as a single Nuon/JSON line 🤔
## After
The database gets displayed like a record
## Future work
It is sort of annoying that we have to load a whole SQLite database into
memory to make this work; it will be impractical for large databases.
I'd like to explore improvements to `CustomValue` that can make this
work more efficiently.
# Description
This creates an option for building binary data from byte integers.
Previously I think you could only do this by formatting the integers to
hex and using `decode hex`.
One potentially confusing thing is that this is different from the `into
binary` behavior. But since this doesn't support any of the other `into
binary` behaviors, it might be okay.
# User-Facing Changes
- `bytes build` accepts single byte arguments as integers
# Tests + Formatting
Example added.
# After Submitting
- [ ] release notes
This PR changes `nu_path::expand_path_with()` to no longer remove
trailing slashes. It also fixes bugs in the current implementation due
to ineffective tests (Fixes#12602).

This PR changes `$env` to be **case-preserving** instead of
case-sensitive. That is, it preserves the case of the environment
variable when it is first assigned, but subsequent retrieval and update
ignores the case.
Notably, both `$env.PATH` and `$env.Path` can now be used to read or set
the environment variable, but child processes will always see the
correct case based on the platform.
Fixes#11268.

This feature was surprising simple to implement, because most of the
infrastructure to support case-insensitive cell path access already
exists. The `get` command extracts data using a cell path in a
case-insensitive way (!), but accepts a `--sensitive` flag. (I think
this should be flipped around?)
# Description
So sorry to do this during the pre-release freeze, but my plugin crate
split PR broke local socket mode, because `nu-plugin-protocol` didn't
have the compile feature to advertise the `LocalSocket` protocol
feature.
This is a very simple, configuration-only bugfix that I think really
needs to be merged before the release, or else local socket mode won't
work at all.
# Tests + Formatting
There's an oversight in my testing that caused this to not be caught:
the engine really did have the feature, but it just wasn't advertising
it, so for `stress_internals` it was still able to use it successfully.
Post-release I'll try to make sure this is properly handled somehow.

# Description
This breaks `nu-plugin` up into four crates:
- `nu-plugin-protocol`: just the type definitions for the protocol, no
I/O. If someone wanted to wire up something more bare metal, maybe for
async I/O, they could use this.
- `nu-plugin-core`: the shared stuff between engine/plugin. Less stable
interface.
- `nu-plugin-engine`: everything required for the engine to talk to
plugins. Less stable interface.
- `nu-plugin`: everything required for the plugin to talk to the engine,
what plugin developers use. Should be the most stable interface.
No changes are made to the interface exposed by `nu-plugin` - it should
all still be there. Re-exports from `nu-plugin-protocol` or
`nu-plugin-core` are used as required. Plugins shouldn't ever have to
use those crates directly.
This should be somewhat faster to compile as `nu-plugin-engine` and
`nu-plugin` can compile in parallel, and the engine doesn't need
`nu-plugin` and plugins don't need `nu-plugin-engine` (except for test
support), so that should reduce what needs to be compiled too.
The only significant change here other than splitting stuff up was to
break the `source` out of `PluginCustomValue` and create a new
`PluginCustomValueWithSource` type that contains that instead. One bonus
of that is we get rid of the option and it's now more type-safe, but it
also means that the logic for that stuff (actually running the plugin
for custom value ops) can live entirely within the `nu-plugin-engine`
crate.
# User-Facing Changes

- Added `local-socket` feature for `nu` to try to make it possible to
compile without that support if needed.

# Description
I would like to help with `polars` plugin development and add tests to
all the `polars` command's existing params.
Since I have never written any lines of Rust, even though the task of
creating tests is relatively simple, I would like to ask for feedback to
ensure I did everything correctly here.
# Description
I found a bunch of issues relating to the specialized reimplementation
of `print()` that's done in `nu-cli` and it just didn't seem necessary.
So I tried to unify the behavior reasonably. `PipelineData::print()`
already handles the call to `table` and it even has a `no_newline`
option.
One of the most major issues before was that we were using the value
iterator, and then converting to string, and then printing each with
newlines. This doesn't work well for an external stream, because its
iterator ends up creating `Value::binary()` with each buffer... so we
were doing lossy UTF-8 conversion on those and then printing them with
newlines, which was very weird:
You can see the random newline inserted in a break between buffers, but
this would be even worse if it were on a multibyte UTF-8 character. You
can produce this by writing a large amount of text to a text file, and
then doing `nu -c 'open file.txt'` - in my case I just wrote `^find .`;
it just has to be large enough to trigger a buffer break.
Using `print()` instead led to a new issue though, because it doesn't
abort on errors. This is so that certain commands can produce a stream
of errors and have those all printed. There are tests for e.g. `rm` that
depend on this behavior. I assume we want to keep that, so instead I
made my target `BufferedReader`, and had that fuse closed if an error
was encountered. I can't imagine we want to keep reading from a wrapped
I/O stream if an error occurs; more often than not the error isn't going
to magically resolve itself, it's not going to be a different error each
time, and it's just going to lead to an infinite stream of the same
error.
The test that broke without that was `open . | lines`, because `lines`
doesn't fuse closed on error. But I don't know if it's expected or not
for it to do that, so I didn't target that.
I think this PR makes things better but I'll keep looking for ways to
improve on how errors and streams interact, especially trying to
eliminate cases where infinite error loops can happen.
# User-Facing Changes
- **Breaking**: `BufferedReader` changes + no more public fields
- A raw I/O stream from e.g. `open` won't produce infinite errors
anymore, but I consider that to be a plus
- the implicit `print` on script output is the same as the normal one
now
# Tests + Formatting
Everything passes but I didn't add anything specific.
# Description
Bandaid fix for #12643, where it is not possible to get the exit code of
a failed external command while also having the external command inherit
nushell's stdout and stderr. This changes `try` so that the exit code of
external command is available in the `catch` block via the usual
`$env.LAST_EXIT_CODE`.
# Tests + Formatting
Added one test.
# After Submitting
Rework I/O redirection and possibly exit codes.

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

# Description
I thought about bringing `nu_plugin_msgpack` in, but that is MPL with a
clause that prevents other licenses, so rather than adapt that code I
decided to take a crack at just doing it straight from `rmp` to `Value`
without any `rmpv` in the middle. It seems like it's probably faster,
though I can't say for sure how much with the plugin overhead.
@IanManske I started on a `Read` implementation for `RawStream` but just
specialized to `from msgpack` here, but I'm thinking after release maybe
we can polish it up and make it a real one. It works!

# Description
Continuing from #12568, this PR further reduces the size of `Expr` from
64 to 40 bytes. It also reduces `Expression` from 128 to 96 bytes and
`Type` from 32 to 24 bytes.
This was accomplished by:
- for `Expr` with multiple fields (e.g., `Expr::Thing(A, B, C)`),
merging the fields into new AST struct types and then boxing this struct
(e.g. `Expr::Thing(Box<ABC>)`).
- replacing `Vec<T>` with `Box<[T]>` in multiple places. `Expr`s and
`Expression`s should rarely be mutated, if at all, so this optimization
makes sense.
By reducing the size of these types, I didn't notice a large performance
improvement (at least compared to #12568). But this PR does reduce the
memory usage of nushell. My config is somewhat light so I only noticed a
difference of 1.4MiB (38.9MiB vs 37.5MiB).

# Description
The local socket PR introduced a `Waitable` type, which could either
hold a value or be waited on until a value is available. Unlike a
channel, it would always return that value once set.
However, one issue with this design was that there was no way to detect
whether a value would ever be written. This splits the writer into a
different type `WaitableMut`, so that when it is dropped, waiting
threads can fail (because they'll never get a value).

# Description
This should fix the sometimes failing wrong version test for
stress_internals.
The plugin interface state stores an error if some kind of critical
error happened, and this error should be propagated to any future
operations on the interface, but this wasn't being propagated to plugin
calls that were already waiting.
During plugin registration, the wrong version error needs to be received
as a response to the `get_signature()` to show up properly, but this
would only happen if `get_signature()` started after the `Hello` was
already received and processed. That would be a race condition, which
this commit solves.

# Description
Adds a new keyword, `plugin use`. Unlike `register`, this merely loads
the signatures from the plugin cache file. The file is configurable with
the `--plugin-config` option either to `nu` or to `plugin use` itself,
just like the other `plugin` family of commands. At the REPL, one might
do this to replace `register`:
```nushell
> plugin add ~/.cargo/bin/nu_plugin_foo
> plugin use foo
```
This will not work in a script, because `plugin use` is a keyword and
`plugin add` does not evaluate at parse time (intentionally). This means
we no longer run random binaries during parse.
The `--plugins` option has been added to allow running `nu` with certain
plugins in one step. This is used especially for the `nu_with_plugins!`
test macro, but I'd imagine is generally useful. The only weird quirk is
that it has to be a list, and we don't really do this for any of our
other CLI args at the moment.
`register` now prints a deprecation parse warning.
This should fix#11923, as we now have a complete alternative to
`register`.
# User-Facing Changes
- Add `plugin use` command
- Deprecate `register`
- Add `--plugins` option to `nu` to replace a common use of `register`
# Tests + Formatting
I think I've tested it thoroughly enough and every existing test passes.
Testing nu CLI options and alternate config files is a little hairy and
I wish there were some more generic helpers for this, so this will go on
my TODO list for refactoring.

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

The panic can happened if we pipe a variable to a custom command which
recursively called itself inside another block.
TBH, I think I figure out how it works to panic, but I'm not sure if
there is a potention issue if nushell don't mutate a block in such case.

# Description
Adds two new types in `nu-engine` for evaluating closures: `ClosureEval`
and `ClosureEvalOnce`. This removed some duplicate code and centralizes
our logic for setting up, running, and cleaning up closures. For
example, in the future if we are able to reduce the cloning necessary to
run a closure, then we only have to change the code related to these
types.
`ClosureEval` and `ClosureEvalOnce` are designed with a builder API.
`ClosureEval` is used to run a closure multiple times whereas
`ClosureEvalOnce` is used for a one-shot closure.
# User-Facing Changes
Should be none, unless I messed up one of the command migrations.
Actually, this will fix any unreported environment bugs for commands
that didn't reset the env after running a closure.
# Description
When saving to a file we currently try to check if the data source in
the pipeline metadata is the same as the file we are saving to. If so,
we create an error, since reading and writing to a file at the same time
is currently not supported/handled gracefully. However, there are still
a few instances where this error is not properly triggered, and so this
PR attempts to reduce these cases. Inspired by #12599.
# Tests + Formatting
Added a few tests.
# After Submitting
Some commands still do not properly preserve metadata (e.g., `str trim`)
and so prevent us from detecting this error.
# Description
This pull request provides three new commands:
`polars store-ls` - moved from `polars ls`. It provides the list of all
object stored in the plugin cache
`polars store-rm` - deletes a cached object
`polars store-get` - gets an object from the cache.
The addition of `polars store-get` required adding a reference_count to
cached entries. `polars get` is the only command that will increment
this value. `polars rm` will remove the value despite it's count. Calls
to PolarsPlugin::custom_value_dropped will decrement the value.
The prefix store- was chosen due to there already being a `polars cache`
command. These commands were not made sub-commands as there isn't a way
to display help for sub commands in plugins (e.g. `polars store`
displaying help) and I felt the store- seemed fine anyways.
The output of `polars store-ls` now shows the reference count for each
object.
# User-Facing Changes
polars ls has now moved to polars store-ls

# Description
The `stress_internals` tests can fail sometimes, but usually not on the
CI, because Nushell exits while the plugin is still trying to read or
maybe write something, leading to a broken pipe.
`nu-plugin` already exits with 1 without printing a message on a
protocol-level I/O error, so this just doing the same thing.
I think there's probably a way to correct the plugin handling so that we
wait for plugins to shut down before exiting and this doesn't happen,
but this is the quick fix in the meantime.

# Description
there was a typo in the doc of `nuon::ToStyle`.

# Description
- Plugin signatures are now saved to `plugin.msgpackz`, which is
brotli-compressed MessagePack.
- The file is updated incrementally, rather than writing all plugin
commands in the engine every time.
- The file always contains the result of the `Signature` call to the
plugin, even if commands were removed.
- Invalid data for a particular plugin just causes an error to be
reported, but the rest of the plugins can still be parsed
# User-Facing Changes
- The plugin file has a different filename, and it's not a nushell
script.
- The default `plugin.nu` file will be automatically migrated the first
time, but not other plugin config files.
- We don't currently provide any utilities that could help edit this
file, beyond `plugin add` and `plugin rm`
- `from msgpackz`, `to msgpackz` could also help
- New commands: `plugin add`, `plugin rm`
# Tests + Formatting
Tests added for the format and for the invalid handling.
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

# Description
`Value` describes the types of first-class values that users and scripts
can create, manipulate, pass around, and store. However, `Block`s are
not first-class values in the language, so this PR removes it from
`Value`. This removes some unnecessary code, and this change should be
invisible to the user except for the change to `scope modules` described
below.
# User-Facing Changes
Breaking change: the output of `scope modules` was changed so that
`env_block` is now `has_env_block` which is a boolean value instead of a
`Block`.
# After Submitting
Update the language guide possibly.
# Description
For a long time, I was searching for the `str extract` command to
extract regexes from strings. I often painfully used `str replace -r
'(.*)(pattern_to_find)(.*)' '$2'` for such purposes.
Only this morning did I realize that `parse` is what I needed for so
many times, which I had only used for parsing data in tables.

Add version details in `version`'s output. The intended use is for
third-party tools to be able to quickly check version numbers without
having to the parsing from `(version).version` or `$env.NU_VERSION`.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

This adds 4 new values to the record from `version`:
```
...
│ major │ 0 │
│ minor │ 92 │
│ patch │ 3 │
│ pre │ a-value │
...
```
`pre` is optional and won't be present most of the time I think.

After this is merged I would like to write docs somewhere for scripts
writer to advise using these members instead of the string values. Where
should I put said docs ?
# Description
This PR improves the `nu --lsp` tooltips by using nu code blocks around
the examples and a few other places.
This is what it looks like in Zed.
Here it is in Helix.
This coloring is far from perfect, but it's what the tree-sitter-nu
queries generate.

# Description
in order to change the style of the _serialized_ NUON data,
`nuon::to_nuon` takes three mutually exclusive arguments, `raw: bool`,
`tabs: Option<usize>` and `indent: Option<usize>` 🤔
this begs to use an enumeration with all possible alternatives, right?
this PR changes the signature of `nuon::to_nuon` to use `nuon::ToStyle`
which has three variants
- `Raw`: no newlines
- `Tabs(n: usize)`: newlines and `n` tabulations as indent
- `Spaces(n: usize)`: newlines and `n` spaces as indent
# User-Facing Changes
the signature of `nuon::to_nuon` changes from
```rust
to_nuon(
input: &Value,
raw: bool,
tabs: Option<usize>,
indent: Option<usize>,
span: Option<Span>,
) -> Result<String, ShellError>
```
to
```rust
to_nuon(
input: &Value,
style: ToStyle,
span: Option<Span>
) -> Result<String, ShellError>
```
