Refactor Record to use a single backing Vec (#12326)
# Description
This shrinks `Record`'s size in half and and allows you to include it in
`Value` without growing the size.

Changing the `Record` internals may have slightly different performance
characteristics as the cache locality changes on lookups (if you
directly need the value, it should be closer, but in other cases may
blow up the cache line budget)

Also different perf characteristics on creation expected. 
`Record::from_raw_cols_vals` now probably worse.

## Benchmarking

Comparison with the main branch (boxed Record) revealed no significant
change to the creation but an improvement when accessing larger N.
The fact that this was more pronounced for nested access (still cloning
before nushell/nushell#12325) leads to the conclusion that this may
still be dominated by the smaller clone necessary for a 24-byte `Record`
over the previous 48 bytes.

Remove serde derive for ShellError, replace via LabeledError (#12319)
# Description

This changes the interface for plugins to always represent errors as
`LabeledError`s. This is good for altlang plugins, as it would suck for
them to have to implement and track `ShellError`. We save a lot of
generated code from the `ShellError` serde impl too, so `nu` and plugins
get to have a smaller binary size.

Reduces the release binary size by 1.2 MiB on my build configuration.

# User-Facing Changes

- Changes plugin protocol. `ShellError` no longer serialized.
- `ShellError` serialize output is different
- `ShellError` no longer deserializes to exactly the same value as
serialized

Reuse existing small allocations if possible (#12335)
Those allocations are all small and insignificant in the grand scheme of
things and the optimizer may be able to resolve some of those but better
to be nice anyways.

Primarily inspired by the new
[`clippy::assigning_clones`](https://rust-lang.github.io/rust-clippy/master/index.html#/assigning_clones)

- **Avoid reallocs with `clone_from` in `nu-parser`**
- **Avoid realloc on assignment in `Stack`**
- **Fix `clippy::assigning_clones` in `nu-cli`**
- **Reuse allocations in `nu-explore` if possible**

Elide clone in V::follow_cell_path for record (#12325)
# Description
This clone is not necessary and tanks the performance of deep nested
access.
As soon as we found the value, we know we discard the old value, so can
`std::mem::take` the inner (`impl Default for Value` to the rescue)

We may be able to further optimize this but not having to clone the
value is vital.

Change PluginCommand API to be more like Command (#12279)
# Description

This is something that was discussed in the core team meeting last
Wednesday. @ayax79 is building `nu-plugin-polars` with all of the
dataframe commands into a plugin, and there are a lot of them, so it
would help to make the API more similar. At the same time, I think the
`Command` API is just better anyway. I don't think the difference is
justified, and the types for core commands have the benefit of requiring
less `.into()` because they often don't own their data

- Broke `signature()` up into `name()`, `usage()`, `extra_usage()`,
`search_terms()`, `examples()`
- `signature()` returns `nu_protocol::Signature`
- `examples()` returns `Vec<nu_protocol::Example>`
- `PluginSignature` and `PluginExample` no longer need to be used by
plugin developers

# User-Facing Changes
Breaking API for plugins yet again 😄

Add command_prelude module (#12291)
# Description
When implementing a `Command`, one must also import all the types
present in the function signatures for `Command`. This makes it so that
we often import the same set of types in each command implementation
file. E.g., something like this:
```rust
use nu_protocol::ast::Call;
use nu_protocol::engine::{Command, EngineState, Stack};
use nu_protocol::{
    record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, PipelineData,
    ShellError, Signature, Span, Type, Value,
};
```

This PR adds the `nu_engine::command_prelude` module which contains the
necessary and commonly used types to implement a `Command`:
```rust
// command_prelude.rs
pub use crate::CallExt;
pub use nu_protocol::{
    ast::{Call, CellPath},
    engine::{Command, EngineState, Stack},
    record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, IntoSpanned,
    PipelineData, Record, ShellError, Signature, Span, Spanned, SyntaxShape, Type, Value,
};
```

This should reduce the boilerplate needed to implement a command and
also gives us a place to track the breadth of the `Command` API. I tried
to be conservative with what went into the prelude modules, since it
might be hard/annoying to remove items from the prelude in the future.
Let me know if something should be included or excluded.

ls, rm, cp, open, touch, mkdir: Don't expand tilde if input path is quoted string or a variable. (#12232)
# Description
Fixes:  #11887
Fixes: #11626

This pr unify the tilde expand behavior over several filesystem relative
commands. It follows the same rule with glob expansion:
|  command  |  result |
| ----------- |  ------ |
| ls ~/aaa  | expand tilde
| ls "~/aaa"  | don't expand tilde
| let f = "~/aaa"; ls $f | don't expand tilde, if you want to: use `ls
($f \| path expand)`
| let f: glob = "~/aaa"; ls $f | expand tilde, they don't expand on
`mkdir`, `touch` comamnd.

Actually I'm not sure for 4th item, currently it's expanding is just
because it followes the same rule with glob expansion.

### About the change
It changes `expand_path_with` to accept a new argument called
`expand_tilde`, if it's true, expand it, if not, just keep it as `~`
itself.

# User-Facing Changes
After this change, `ls "~/aaa"` won't expand tilde.

Add test support crate for plugin developers (#12259)
# Description

Adds a `nu-plugin-test-support` crate with an interface that supports
testing plugins.

Unlike in reality, these plugins run in the same process on separate
threads. This will allow
testing aspects of the plugin internal state and handling serialized
plugin custom values easily.
We still serialize their custom values and all of the engine to plugin
logic is still in play, so
from a logical perspective this should still expose any bugs that would
have been caused by that.
The only difference is that it doesn't run in a different process, and
doesn't try to serialize
everything to the final wire format for stdin/stdout.

TODO still:

- [x] Clean up warnings about private types exposed in trait definition
- [x] Automatically deserialize plugin custom values in the result so
they can be inspected
- [x] Automatic plugin examples test function
- [x] Write a bit more documentation
- [x] More tests
- [x] Add MIT License file to new crate

# User-Facing Changes

Plugin developers get a nice way to test their plugins.

# Tests + Formatting
Run the tests with `cargo test -p nu-plugin-test-support --
--show-output` to see some examples of what the failing test output for
examples can look like. I used the `difference` crate (MIT licensed) to
make it look nice.

Better generic errors for plugins (and perhaps scripts) (#12236)
# Description
This makes `LabeledError` much more capable of representing close to
everything a `miette::Diagnostic` can, including `ShellError`, and
allows plugins to generate multiple error spans, codes, help, etc.

`LabeledError` is now embeddable within `ShellError` as a transparent
variant.

This could also be used to improve `error make` and `try/catch` to
reflect `LabeledError` exactly in the future.

Also cleaned up some errors in existing plugins.

Refactor source cache into CachedFile struct (#12240)
# Description
Get rid of two parallel `Vec`s in `StateDelta` and `EngineState`, that
also duplicated span information. Use a struct with documenting fields.

Also use `Arc<str>` and `Arc<[u8]>` for the allocations as they are
never modified and cloned often (see #12229 for the first improvement).
This also makes the representation more compact as no capacity is
necessary.

Make EngineState clone cheaper with Arc on all of the heavy objects (#12229)
# Description
This makes many of the larger objects in `EngineState` into `Arc`, and
uses `Arc::make_mut` to do clone-on-write if the reference is not
unique. This is generally very cheap, giving us the best of both worlds
- allowing us to mutate without cloning if we have an exclusive
reference, and cloning if we don't.

This started as more of a curiosity for me after remembering that
`Arc::make_mut` exists and can make using `Arc` for mostly immutable
data that sometimes needs to be changed very convenient, and also after
hearing someone complain about memory usage on Discord - this is a
somewhat significant win for that.

The exact objects that were wrapped in `Arc`:

- `files`, `file_contents` - the strings and byte buffers
- `decls` - the whole `Vec`, but mostly to avoid lots of individual
`malloc()` calls on Clone rather than for memory usage
- `blocks` - the blocks themselves, rather than the outer Vec
- `modules` - the modules themselves, rather than the outer Vec
- `env_vars`, `previous_env_vars` - the entire maps
- `config`

The changes required were relatively minimal, but this is a breaking API
change. In particular, blocks are added as Arcs, to allow the parser
cache functionality to work.

With my normal nu config, running on Linux, this saves me about 15 MiB
of process memory usage when running interactively (65 MiB → 50 MiB).

This also makes quick command executions cheaper, particularly since
every REPL loop now involves a clone of the engine state so that we can
recover from a panic. It also reduces memory usage where engine state
needs to be cloned and sent to another thread or kept within an
iterator.

# User-Facing Changes
Shouldn't be any, since it's all internal stuff, but it does change some
public interfaces so it's a breaking change

Make custom value type handling more consistent (#12230)
[Context on
Discord](https://discord.com/channels/601130461678272522/855947301380947968/1219425984990806207)

# Description

- Rename `CustomValue::value_string()` to `type_name()` to reflect its
usage better.
- Change print behavior to always call `to_base_value()` first, to give
the custom value better control over the output.
- Change `describe --detailed` to show the type name as the subtype,
rather than trying to describe the base value.
- Change custom `Type` to use `type_name()` rather than `typetag_name()`
to make things like `PluginCustomValue` more transparent

One question: should `describe --detailed` still include a description
of the base value somewhere? I'm torn on it, it seems possibly useful
for some things (maybe sqlite databases?), but having `describe -d` not
include the custom type name anywhere felt weird. Another option would
be to add another method to `CustomValue` for info to be displayed in
`describe`, so that it can be more type-specific?

Everything above has implications for printing and `describe` on custom
values

Reorganize plugin API around commands (#12170)
[Context on
Discord](https://discord.com/channels/601130461678272522/855947301380947968/1216517833312309419)

# Description
This is a significant breaking change to the plugin API, but one I think
is worthwhile. @ayax79 mentioned on Discord that while trying to start
on a dataframes plugin, he was a little disappointed that more wasn't
provided in terms of code organization for commands, particularly since
there are *a lot* of `dfr` commands.

This change treats plugins more like miniatures of the engine, with
dispatch of the command name being handled inherently, each command
being its own type, and each having their own signature within the trait
impl for the command type rather than having to find a way to centralize
it all into one `Vec`.

For the example plugins that have multiple commands, I definitely like
how this looks a lot better. This encourages doing code organization the
right way and feels very good.

For the plugins that have only one command, it's just a little bit more
boilerplate - but still worth it, in my opinion.

The `Box<dyn PluginCommand<Plugin = Self>>` type in `commands()` is a
little bit hairy, particularly for Rust beginners, but ultimately not so
bad, and it gives the desired flexibility for shared state for a whole
plugin + the individual commands.

# User-Facing Changes
Pretty big breaking change to plugin API, but probably one that's worth
making.

```rust
use nu_plugin::*;
use nu_protocol::{PluginSignature, PipelineData, Type, Value};

struct LowercasePlugin;
struct Lowercase;

IO and redirection overhaul (#11934)
# Description
The PR overhauls how IO redirection is handled, allowing more explicit
and fine-grain control over `stdout` and `stderr` output as well as more
efficient IO and piping.

To summarize the changes in this PR:
- Added a new `IoStream` type to indicate the intended destination for a
pipeline element's `stdout` and `stderr`.
- The `stdout` and `stderr` `IoStream`s are stored in the `Stack` and to
avoid adding 6 additional arguments to every eval function and
`Command::run`. The `stdout` and `stderr` streams can be temporarily
overwritten through functions on `Stack` and these functions will return
a guard that restores the original `stdout` and `stderr` when dropped.
- In the AST, redirections are now directly part of a `PipelineElement`
as a `Option<Redirection>` field instead of having multiple different
`PipelineElement` enum variants for each kind of redirection. This
required changes to the parser, mainly in `lite_parser.rs`.
- `Command`s can also set a `IoStream` override/redirection which will
apply to the previous command in the pipeline. This is used, for
example, in `ignore` to allow the previous external command to have its
stdout redirected to `Stdio::null()` at spawn time. In contrast, the
current implementation has to create an os pipe and manually consume the
output on nushell's side. File and pipe redirections (`o>`, `e>`, `e>|`,
etc.) have precedence over overrides from commands.

This PR improves piping and IO speed, partially addressing #10763. Using
the `throughput` command from that issue, this PR gives the following
speedup on my setup for the commands below:
| Command | Before (MB/s) | After (MB/s) | Bash (MB/s) |
| --------------------------- | -------------:| ------------:|
-----------:|
| `throughput o> /dev/null` | 1169 | 52938 | 54305 |
| `throughput \| ignore` | 840 | 55438 | N/A |
| `throughput \| null` | Error | 53617 | N/A |
| `throughput \| rg 'x'` | 1165 | 3049 | 3736 |
| `(throughput) \| rg 'x'` | 810 | 3085 | 3815 |

(Numbers above are the median samples for throughput)

This PR also paves the way to refactor our `ExternalStream` handling in
the various commands. For example, this PR already fixes the following
code:
```nushell
^sh -c 'echo -n "hello "; sleep 0; echo "world"' | find "hello world"
```
This returns an empty list on 0.90.1 and returns a highlighted "hello
world" on this PR.

Since the `stdout` and `stderr` `IoStream`s are available to commands
when they are run, then this unlocks the potential for more convenient
behavior. E.g., the `find` command can disable its ansi highlighting if
it detects that the output `IoStream` is not the terminal. Knowing the
output streams will also allow background job output to be redirected
more easily and efficiently.

# User-Facing Changes
- External commands returned from closures will be collected (in most
cases):
  ```nushell
  1..2 | each {|_| nu -c "print a" }
  ```
This gives `["a", "a"]` on this PR, whereas this used to print "a\na\n"
and then return an empty list.

  ```nushell
  1..2 | each {|_| nu -c "print -e a" }
  ```
This gives `["", ""]` and prints "a\na\n" to stderr, whereas this used
to return an empty list and print "a\na\n" to stderr.

- Trailing new lines are always trimmed for external commands when
piping into internal commands or collecting it as a value. (Failure to
decode the output as utf-8 will keep the trailing newline for the last
binary value.) In the current nushell version, the following three code
snippets differ only in parenthesis placement, but they all also have
different outputs:

  1. `1..2 | each { ^echo a }`
     ```
     a
     a
     ╭────────────╮
     │ empty list │
     ╰────────────╯
     ```
  2. `1..2 | each { (^echo a) }`
     ```
     ╭───┬───╮
     │ 0 │ a │
     │ 1 │ a │
     ╰───┴───╯
     ```
  3. `1..2 | (each { ^echo a })`
     ```
     ╭───┬───╮
     │ 0 │ a │
     │   │   │
     │ 1 │ a │
     │   │   │
     ╰───┴───╯
     ```

  But in this PR, the above snippets will all have the same output:
  ```
  ╭───┬───╮
  │ 0 │ a │
  │ 1 │ a │
  ╰───┴───╯
  ```

- All existing flags on `run-external` are now deprecated.

- File redirections now apply to all commands inside a code block:
  ```nushell
  (nu -c "print -e a"; nu -c "print -e b") e> test.out
  ```
This gives "a\nb\n" in `test.out` and prints nothing. The same result
would happen when printing to stdout and using a `o>` file redirection.

- External command output will (almost) never be ignored, and ignoring
output must be explicit now:
  ```nushell
  (^echo a; ^echo b)
  ```
This prints "a\nb\n", whereas this used to print only "b\n". This only
applies to external commands; values and internal commands not in return
position will not print anything (e.g., `(echo a; echo b)` still only
prints "b").

- `complete` now always captures stderr (`do` is not necessary).

Because `std::fs::canonicalize` requires the path to exist, this PR
makes it so that when canonicalizing any config file, the
`$nu.default-config-dir/nushell` part is canonicalized first, then
`$nu.default-config-dir/nushell/foo.nu` is canonicalized.

This should also fix the issue @devyn pointed out
[here](https://github.com/nushell/nushell/pull/12118#issuecomment-1989546708)
where a couple of the tests failed if one's `~/.config/nushell` folder
was actually a symlink to a different folder. The tests previously
didn't canonicalize the expected paths.

I was going to make a PR that caches the config directory on startup (as
suggested by fdncred and Ian in Discord), but I can make that part of
this PR if we want to avoid creating unnecessary PRs. I think it
probably makes more sense to separate them though.

Support for all custom value operations on plugin custom values (#12088)
# Description

Adds support for the following operations on plugin custom values, in
addition to `to_base_value` which was already present:

- `follow_path_int()`
- `follow_path_string()`
- `partial_cmp()`
- `operation()`
- `Drop` (notification, if opted into with
`CustomValue::notify_plugin_on_drop`)

There are additionally customizable methods within the `Plugin` and
`StreamingPlugin` traits for implementing these functions in a way that
requires access to the plugin state, as a registered handle model such
as might be used in a dataframes plugin would.

`Value::append` was also changed to handle custom values correctly.

# User-Facing Changes

- Signature of `CustomValue::follow_path_string` and
`CustomValue::follow_path_int` changed to give access to the span of the
custom value itself, useful for some errors.
- Plugins using custom values have to be recompiled because the engine
will try to do custom value operations that aren't supported
- Plugins can do more things 🎉

Closes #12103

# Description
<!--
Thank you for improving Nushell. Please, check our [contributing

As described in #12103, this PR makes Nushell use `XDG_CONFIG_HOME` as
the config directory if it exists. Otherwise, it uses the old behavior,
which was to use `dirs_next::config_dir()`.

Edit: We discussed choosing between `XDG_CONFIG_HOME` and the default
config directory in Discord and decided against it, at least for now.

<s>@kubouch also suggested letting users choose between
`XDG_CONFIG_HOME` and the default config directory if config files
aren't found on startup and `XDG_CONFIG_HOME` is set to a value
different from the default config directory</s>

On Windows and MacOS, if the `XDG_CONFIG_HOME` variable is set but
`XDG_CONFIG_HOME` is either empty or doesn't exist *and* the old config
directory is non-empty, Nushell will issue a warning on startup saying
that it won't move files from the old config directory to the new one.
To do this, I had to add a `nu_path::config_dir_old()` function. I
assume that at some point, we will remove the warning message and the
function can be removed too. Alternatively, instead of having that
function there, `main.rs` could directly call `dirs_next::config_dir()`.

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

When `$env.XDG_CONFIG_HOME` is set to an absolute path, Nushell will use
`$"($env.XDG_CONFIG_HOME)/nushell"` as its config directory (previously,
this only worked on Linux).

To use `App Data\Roaming` (Windows) or `Library/Application Support`
(MacOS) instead (the old behavior), one can either leave
`XDG_CONFIG_HOME` unset or set it to an empty string.

If `XDG_CONFIG_HOME` is set, but to a non-absolute/invalid path, Nushell
will report an error on startup and use the default config directory
instead:

to set `XDG_CONFIG_HOME` to, say, `~/.config/nushell` rather than
`~/.config`, so the documentation could warn about that mistake.

Keep plugins persistently running in the background (#12064)
# Description
This PR uses the new plugin protocol to intelligently keep plugin
processes running in the background for further plugin calls.

Running plugins can be seen by running the new `plugin list` command,
and stopped by running the new `plugin stop` command.

This is an enhancement for the performance of plugins, as starting new
plugin processes has overhead, especially for plugins in languages that
take a significant amount of time on startup. It also enables plugins
that have persistent state between commands, making the migration of
features like dataframes and `stor` to plugins possible.

Plugins are automatically stopped by the new plugin garbage collector,
configurable with `$env.config.plugin_gc`:

```nushell
  $env.config.plugin_gc = {
      # Configuration for plugin garbage collection
      default: {
          enabled: true # true to enable stopping of inactive plugins
          stop_after: 10sec # how long to wait after a plugin is inactive to stop it
      }
      plugins: {
          # alternate configuration for specific plugins, by name, for example:
          #
          # gstat: {
          #     enabled: false
          # }
      }
  }
```

If garbage collection is enabled, plugins will be stopped after
`stop_after` passes after they were last active. Plugins are counted as
inactive if they have no running plugin calls. Reading the stream from
the response of a plugin call is still considered to be activity, but if
a plugin holds on to a stream but the call ends without an active
streaming response, it is not counted as active even if it is reading
it. Plugins can explicitly disable the GC as appropriate with
`engine.set_gc_disabled(true)`.

The `version` command now lists plugin names rather than plugin
commands. The list of plugin commands is accessible via `plugin list`.

Recommend doing this together with #12029, because it will likely force
plugin developers to do the right thing with mutability and lead to less
unexpected behavior when running plugins nested / in parallel.

# User-Facing Changes
- new command: `plugin list`
- new command: `plugin stop`
- changed command: `version` (now lists plugin names, rather than
commands)
- new config: `$env.config.plugin_gc`
- Plugins will keep running and be reused, at least for the configured
GC period
- Plugins that used mutable state in weird ways like `inc` did might
misbehave until fixed
- Plugins can disable GC if they need to
- Had to change plugin signature to accept `&EngineInterface` so that
the GC disable feature works. #12029 does this anyway, and I'm expecting
(resolvable) conflicts with that

# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

Because there is some specific OS behavior required for plugins to not
respond to Ctrl-C directly, I've developed against and tested on both
Linux and Windows to ensure that works properly.

I think this probably needs to be in the book somewhere

Add support for engine calls from plugins (#12029)
# Description

This allows plugins to make calls back to the engine to get config,
evaluate closures, and do other things that must be done within the
engine process.

Engine calls can both produce and consume streams as necessary. Closures
passed to plugins can both accept stream input and produce stream output
sent back to the plugin.

Engine calls referring to a plugin call's context can be processed as
long either the response hasn't been received, or the response created
streams that haven't ended yet.

This is a breaking API change for plugins. There are some pretty major
changes to the interface that plugins must implement, including:

1. Plugins now run with `&self` and must be `Sync`. Executing multiple
plugin calls in parallel is supported, and there's a chance that a
closure passed to a plugin could invoke the same plugin. Supporting
state across plugin invocations is left up to the plugin author to do in
whichever way they feel best, but the plugin object itself is still
shared. Even though the engine doesn't run multiple plugin calls through
the same process yet, I still considered it important to break the API
in this way at this stage. We might want to consider an optional
threadpool feature for performance.

2. Plugins take a reference to `EngineInterface`, which can be cloned.
This interface allows plugins to make calls back to the engine,
including for getting config and running closures.

3. Plugins no longer take the `config` parameter. This can be accessed
from the interface via the `.get_plugin_config()` engine call.


# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
Not only does this have plugin protocol changes, it will require plugins
to make some code changes before they will work again. But on the plus
side, the engine call feature is extensible, and we can add more things
to it as needed.

Plugin maintainers will have to change the trait signature at the very
least. If they were using `config`, they will have to call
`engine.get_plugin_config()` instead.

If they were using the mutable reference to the plugin, they will have
to come up with some strategy to work around it (for example, for `Inc`
I just cloned it). This shouldn't be such a big deal at the moment as
it's not like plugins have ever run as daemons with persistent state in
the past, and they don't in this PR either. But I thought it was
important to make the change before we support plugins as daemons, as an
exclusive mutable reference is not compatible with parallel plugin
calls.

I suggest this gets merged sometime *after* the current pending release,
so that we have some time to adjust to the previous plugin protocol
changes that don't require code changes before making ones that do.

# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`


# After Submitting
I will document the additional protocol features (`EngineCall`,
`EngineCallResponse`), and constraints on plugin call processing if
engine calls are used - basically, to be aware that an engine call could
result in a nested plugin call, so the plugin should be able to handle
that.

Allow for stacks to have parents (#11654)
This is another attempt on #11288 

This allows for a `Stack` to have a parent stack (behind an `Arc`). This
is being added to avoid constant stack copying in REPL code.

Concretely the following changes are included here:
- `Stack` can now have a `parent_stack`, pointing to another stack
- variable lookups can fallback to this parent stack (env vars and
everything else is still copied)
- REPL code has been reworked so that we use parenting rather than
cloning. A REPL-code-specific trait helps to ensure that we do not
accidentally trigger a full clone of the main stack
- A property test has been added to make sure that parenting "looks the
same" as cloning for consumers of `Stack` objects

This PR adds a new evaluator path with callbacks to a mutable trait
object implementing a Debugger trait. The trait object can do anything,
e.g., profiling, code coverage, step debugging. Currently,
entering/leaving a block and a pipeline element is marked with
callbacks, but more callbacks can be added as necessary. Not all
callbacks need to be used by all debuggers; unused ones are simply empty
calls. A simple profiler is implemented as a proof of concept.

The debugging support is implementing by making `eval_xxx()` functions
generic depending on whether we're debugging or not. This has zero
computational overhead, but makes the binary slightly larger (see
benchmarks below). `eval_xxx()` variants called from commands (like
`eval_block_with_early_return()` in `each`) are chosen with a dynamic
dispatch for two reasons: to not grow the binary size due to duplicating
the code of many commands, and for the fact that it isn't possible
because it would make Command trait objects object-unsafe.

In the future, I hope it will be possible to allow plugin callbacks such
that users would be able to implement their profiler plugins instead of
having to recompile Nushell.
[DAP](https://microsoft.github.io/debug-adapter-protocol/) would also be
interesting to explore.

Try `help debug profile`.

## Screenshots

Basic output:

![profiler_new](https://github.com/nushell/nushell/assets/25571562/418b9df0-b659-4dcb-b023-2d5fcef2c865)

To profile with more granularity, increase the profiler depth (you'll
see that repeated `is-windows` calls take a large chunk of total time,
making it a good candidate for optimizing):

![profiler_new_m3](https://github.com/nushell/nushell/assets/25571562/636d756d-5d56-460c-a372-14716f65f37f)

## Benchmarks

### Binary size

Binary size increase vs. main: **+40360 bytes**. _(Both built with
`--release --features=extra,dataframe`.)_

### Time

```nushell
# bench_debug.nu
use std bench

let test = {
    1..100
    | each {
        ls | each {|row| $row.name | str length }
    }
    | flatten
    | math avg
}

print 'debug:'
let res2 = bench { debug profile $test } --pretty
print $res2
```

```nushell
# bench_nodebug.nu
use std bench

let test = {
    1..100
    | each {
        ls | each {|row| $row.name | str length }
    }
    | flatten
    | math avg
}

print 'no debug:'
let res1 = bench { do $test } --pretty
print $res1
```

`cargo run --release -- bench_debug.nu` is consistently 1--2 ms slower
than `cargo run --release -- bench_nodebug.nu` due to the collection
overhead + gathering the report. This is expected. When gathering more
stuff, the overhead is obviously higher.

`cargo run --release -- bench_nodebug.nu` vs. `nu bench_nodebug.nu` I
didn't measure any difference. Both benchmarks report times between 97
and 103 ms randomly, without one being consistently higher than the
other. This suggests that at least in this particular case, when not
running any debugger, there is no runtime overhead.

## API changes

This PR adds a generic parameter to all `eval_xxx` functions that forces
you to specify whether you use the debugger. You can resolve it in two
ways:
* Use a provided helper that will figure it out for you. If you wanted
to use `eval_block(&engine_state, ...)`, call `let eval_block =
get_eval_block(&engine_state); eval_block(&engine_state, ...)`
* If you know you're in an evaluation path that doesn't need debugger
support, call `eval_block::<WithoutDebug>(&engine_state, ...)` (this is
the case of hooks, for example).

I tried to add more explanation in the docstring of `debugger_trait.rs`.

## TODO

- [x] Better profiler output to reduce spam of iterative commands like
`each`
- [x] Resolve `TODO: DEBUG` comments
- [x] Resolve unwraps
- [x] Add doc comments
- [x] Add usage and extra usage for `debug profile`, explaining all
columns

Introduce workspace dependencies (#12043)
# Description
This PR introduces [workspaces
dependencies](https://doc.rust-lang.org/cargo/reference/workspaces.html#the-dependencies-table).
The advantages are:
- a single place where dependency versions are declared
- reduces the number of files to change when upgrading a dependency
- reduces the risk of accidentally depending on 2 different versions of
the same dependency

I've only done a few so far. If this PR is accepted, I might continue
and progressively do the rest.

I've added a couple of tests to check that even if the config folder
and/or any of the config files within are symlinks, the `$nu.*`
variables are properly canonicalized. These tests unfortunately only run
on Linux and MacOS, because I couldn't figure out how to change the
config directory on Windows. Also, given that they involve creating
files, I'm not sure if they're excessive, so I could remove one or two
of them.

Replace panics with errors in thread spawning (#12040)
# Description
Replace panics with errors in thread spawning.

Also adds `IntoSpanned` trait for easily constructing `Spanned`, and an
implementation of `From<Spanned<std::io::Error>>` for `ShellError`,
which is used to provide context for the error wherever there was a span
conveniently available. In general this should make it more convenient
to do the right thing with `std::io::Error` and always add a span to it
when it's possible to do so.

Glob: don't allow implicit casting between glob and string (#11992)
# Description
As title, currently on latest main, nushell confused user if it allows
implicit casting between glob and string:
```nushell
let x = "*.txt"
def glob-test [g: glob] { open $g } 
glob-test $x
```
It always expand the glob although `$x` is defined as a string.
This pr implements a solution from @kubouch :
> We could make it really strict and disallow all autocasting between
globs and strings because that's what's causing the "magic" confusion.
Then, modify all builtins that accept globs to accept oneof(glob,
string) and the rules would be that globs always expand and strings
never expand

# User-Facing Changes
After this pr, user needs to use `into glob` to invoke `glob-test`, if
user pass a string variable:
```nushell
let x = "*.txt"
def glob-test [g: glob] { open $g } 
glob-test ($x | into glob)
```
Or else nushell will return an error.
```
 3 │ glob-test $x
   ·           ─┬
   ·            ╰── can't convert string to glob

Currently, there's multiple places that look for a config directory, and
each of them has different error messages when it can't be found. This
PR makes a `ConfigDirNotFound` error to standardize the error message
for all of these cases.

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

Previously, the errors in `create_nu_constant()` would say which config
file Nushell was trying to get when it couldn't find the config
directory. Now it doesn't. However, I think that's fine, given that it
doesn't matter whether it couldn't find the config directory while
looking for `login.nu` or `env.nu`, it only matters that it couldn't
find it.

This is what the error looks like:

changes.

Span fields were previously renamed to `internal_span` to discourage
their use in Rust code, but this change also affected the serde I/O for
Value. I don't believe the Python plugin was ever updated to reflect
this change.

This effectively changes it back, but just for the serialized form.
There are good reasons for doing this:

1. `internal_span` is a much longer name, and would be one of the most
common strings found in serialized Value data, probably bulking up the
plugin I/O

2. This change was never really meant to have implications for plugins,
and was just meant to be a hint that `.span()` should be used instead in
Rust code.

When Span refactoring is complete, the serialized form of Value will
probably change again in some significant way, so I think for now it's
best that it's left like this.

This has implications for #11911, particularly for documentation and for
the Python plugin as that was already updated in that PR to reflect
`internal_span`. If this is merged first, I will update that PR.

This would probably be considered a breaking change as it would break
plugin I/O compatibility (but not Rust code). I think it can probably go
in any major release though - all things considered, it's pretty minor,
and users are already expected to recompile plugins for new major
versions. However, it may also be worth holding off to do it together
with #11911 as that PR makes breaking changes in general a little bit
friendlier.

# User-Facing Changes

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

Nothing outside of `Value` itself had to be changed to make tests pass.
I did not check the Python plugin and whether it works now, but it was
broken before. It may work again as I think the main incompatibility it
had was expecting to use `span`

Avoid unnecessary allocations or larger iterator structs

- Turn static `Vec`s into arrays when possible
- Use `std::iter::once`/`empty` where applicable
- Use `bool::then_some` in `detect column` `.chain`
- Drop in the bucket: de-vec-ing tests

Related to #11928 - `tee --stderr` doesn't really work as expected
without it

Print stderr streams to stderr in `pipeline_data::print_if_stream()`

This corrects unexpected behavior if a stream from an external program
is transformed while still preserving its stderr output. Before this
change, that output is just drained and discarded. Worse, it's drained
to a buffer, which could be really slow and memory hungry if there's a
lot of output on stderr.

This is needed to make `tee --stderr` function in a non-surprising way.
See #11928

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

A script that was erroneously not producing stderr output before might
now, but I can't think of a lot of examples of an external stream being
transformed without being converted.

open, rm, umv, cp, rm and du: Don't globs if inputs are variables or string interpolation (#11886)
# Description
This is a follow up to
https://github.com/nushell/nushell/pull/11621#issuecomment-1937484322

Also Fixes: #11838 

## About the code change
It applys the same logic when we pass variables to external commands:


0487e9ffcb/crates/nu-command/src/system/run_external.rs (L162-L170)

That is: if user input dynamic things(like variables, sub-expression, or
string interpolation), it returns a quoted `NuPath`, then user input
won't be globbed
 
# User-Facing Changes
Given two input files: `a*c.txt`, `abc.txt`

* `let f = "a*c.txt"; rm $f` will remove one file: `a*c.txt`. 
~* `let f = "a*c.txt"; rm --glob $f` will remove `a*c.txt` and
`abc.txt`~
* `let f: glob = "a*c.txt"; rm $f` will remove `a*c.txt` and `abc.txt`

## Rules about globbing with *variable*
Given two files: `a*c.txt`, `abc.txt`
| Cmd Type | example | Result |
| ----- | ------------------ | ------ |
| builtin | let f = "a*c.txt"; rm $f | remove `a*c.txt` |
| builtin | let f: glob = "a*c.txt"; rm $f | remove `a*c.txt` and
`abc.txt`
| builtin | let f = "a*c.txt"; rm ($f \| into glob) | remove `a*c.txt`
and `abc.txt`
| custom | def crm [f: glob] { rm $f }; let f = "a*c.txt"; crm $f |
remove `a*c.txt` and `abc.txt`
| custom | def crm [f: glob] { rm ($f \| into string) }; let f =
"a*c.txt"; crm $f | remove `a*c.txt`
| custom | def crm [f: string] { rm $f }; let f = "a*c.txt"; crm $f |
remove `a*c.txt`
| custom | def crm [f: string] { rm $f }; let f = "a*c.txt"; crm ($f \|
into glob) | remove `a*c.txt` and `abc.txt`

In general, if a variable is annotated with `glob` type, nushell will
expand glob pattern. Or else, we need to use `into | glob` to expand
glob pattern

# Tests + Formatting
Done

# After Submitting
I think `str glob-escape` command will be no-longer required. We can
remove it.

Debug assertions don't run at release, which means that `cargo test
--release` fails because the tests for name checks don't run properly.
These checks are not really expensive, and there shouldn't be any
noticeable difference to startup time, so there isn't much reason not to
just leave them in.

It's valuable to be able to run `cargo test --release`, as that can
expose race conditions and dependencies on undefined behavior that
aren't exposed in debug builds.

This shouldn't affect anything. Any violations of this rule were being

wrapping run_repl with catch_unwind and restarting the repl on panic (#11860)
Provides the ability to cleanly recover from panics, falling back to the
last known good state of EngineState and Stack. This pull request also
utilizes miette's panic handler for better formatting of panics.

Specify which file not found in error (#11868)
# Description
Currently, `ShellError::FileNotFound` shows the span where the error
occurred but doesn't say which file wasn't found. This PR makes it so
the help includes that (like the `DirectoryNotFound` error).

# User-Facing Changes
No breaking changes, it's just that when a file can't be found, the help
will say which file couldn't be found:

Remove unused Index(Mut) impls on AST types (#11903)
# Description
Both `Block` and `Pipeline` had `Index`/`IndexMut` implementations to
access their elements, that are currently unused.
Explicit helpers or iteration would generally be preferred anyways but
in the current state the inner containers are `pub` and are liberally
used. (Sometimes with potentially panicking indexing or also iteration)

As it is potentially unclear what the meaning of the element from a
block or pipeline queried by a usize is, let's remove it entirely until
we come up with a better API.

# User-Facing Changes
None

Plugin authors shouldn't dig into AST internals

# Description
Hi, 

Fixes #10838, where before the `date` would be formatted incorrectly,
and was not picking `LC_TIME` for time formatting, but it picked the
first locale returned by the `sys-locale` crate instead. Now it will
format time based on `LC_TIME`. For example,

```
// my locale `nl_NL.UTF-8`
❯ date now | format date '%x %X'
20-02-24 17:17:12

$env.LC_TIME = "en_US.UTF-8"

❯ date now | format date '%x %X'
02/20/2024 05:16:28 PM
```
Note that I also changed the `default_env.nu` as otherwise the Time will
show AM/PM twice. Also reason for the `chrono` update is because this
relies on a fix to upstream repo, which i initially submitted an
[issue](https://github.com/chronotope/chrono/issues/1349#event-11765363286)

Add Value::coerce_str (#11885)
# Description
Following #11851, this PR adds one final conversion function for
`Value`. `Value::coerce_str` takes a `&Value` and converts it to a
`Cow<str>`, creating an owned `String` for types that needed converting.
Otherwise, it returns a borrowed `str` for `String` and `Binary`
`Value`s which avoids a clone/allocation. Where possible, `coerce_str`
and `coerce_into_string` should be used instead of `coerce_string`,
since `coerce_string` always allocates a new `String`.

Name the Value conversion functions more clearly (#11851)
# Description
This PR renames the conversion functions on `Value` to be more consistent.
It follows the Rust [API guidelines](https://rust-lang.github.io/api-guidelines/naming.html#ad-hoc-conversions-follow-as_-to_-into_-conventions-c-conv) for ad-hoc conversions.
The conversion functions on `Value` now come in a few forms:
- `coerce_{type}` takes a `&Value` and attempts to convert the value to
`type` (e.g., `i64` are converted to `f64`). This is the old behavior of
some of the `as_{type}` functions -- these functions have simply been
renamed to better reflect what they do.
- The new `as_{type}` functions take a `&Value` and returns an `Ok`
result only if the value is of `type` (no conversion is attempted). The
returned value will be borrowed if `type` is non-`Copy`, otherwise an
owned value is returned.
- `into_{type}` exists for non-`Copy` types, but otherwise does not
attempt conversion just like `as_type`. It takes an owned `Value` and
always returns an owned result.
- `coerce_into_{type}` has the same relationship with `coerce_{type}` as
`into_{type}` does with `as_{type}`.
- `to_{kind}_string`: conversion to different string formats (debug,
abbreviated, etc.). Only two of the old string conversion functions were
removed, the rest have been renamed only.
- `to_{type}`: other conversion functions. Currently, only `to_path`
exists. (And `to_string` through `Display`.)

This table summaries the above:
| Form | Cost | Input Ownership | Output Ownership | Converts `Value`
case/`type` |
| ---------------------------- | ----- | --------------- |
---------------- | -------- |
| `as_{type}` | Cheap | Borrowed | Borrowed/Owned | No |
| `into_{type}` | Cheap | Owned | Owned | No |
| `coerce_{type}` | Cheap | Borrowed | Borrowed/Owned | Yes |
| `coerce_into_{type}` | Cheap | Owned | Owned | Yes |
| `to_{kind}_string` | Expensive | Borrowed | Owned | Yes |
| `to_{type}` | Expensive | Borrowed | Owned | Yes |

# User-Facing Changes
Breaking API change for `Value` in `nu-protocol` which is exposed as
part of the plugin API.

Spreading lists automatically when calling externals was deprecated in
0.89 (#11289), and this PR is to remove it in 0.91.

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

The new error message looks like this:

```
>  ^echo [1 2]
Error: nu:🐚:cannot_pass_list_to_external

  × Lists are not automatically spread when calling external commands
   ╭─[entry #13:1:8]
 1 │  ^echo [1 2]
   ·        ──┬──
   ·          ╰── Spread operator (...) is necessary to spread lists
   ╰────
  help: Either convert the list to a string or use the spread operator, like so: ...[1 2]
```

The old error message didn't say exactly where to put the `...` and
seemed to confuse a lot of people, so hopefully this helps.

Support redirect stderr and stdout+stderr with a pipe (#11708)
# Description
Close: #9673
Close: #8277
Close: #10944

This pr introduces the following syntax:
1. `e>|`, pipe stderr to next command. Example: `$env.FOO=bar nu
--testbin echo_env_stderr FOO e>| str length`
2. `o+e>|` and `e+o>|`, pipe both stdout and stderr to next command,
example: `$env.FOO=bar nu --testbin echo_env_mixed out-err FOO FOO e+o>|
str length`

Note: it only works for external commands. ~There is no different for
internal commands, that is, the following three commands do the same
things:~ Edit: it raises errors if we want to pipes for internal
commands
``` 
❯ ls e>| str length
Error:   × `e>|` only works with external streams
   ╭─[entry #1:1:1]
 1 │ ls e>| str length
   ·    ─┬─
   ·     ╰── `e>|` only works on external streams
   ╰────

❯ ls e+o>| str length
Error:   × `o+e>|` only works with external streams
   ╭─[entry #2:1:1]
 1 │ ls e+o>| str length
   ·    ──┬──
   ·      ╰── `o+e>|` only works on external streams
   ╰────
```

This can help us to avoid some strange issues like the following:

`$env.FOO=bar (nu --testbin echo_env_stderr FOO) e>| str length`

Which is hard to understand and hard to explain to users.

Enforce call stack depth limit for all calls (#11729)
# Description
Previously, only direcly-recursive calls were checked for recursion
depth. But most recursive calls in nushell are mutually recursive since
expressions like `for`, `where`, `try` and `do` all execute a separte
block.

```nushell
def f [] {
    do { f }
}
```
Calling `f` would crash nushell with a stack overflow.

I think the only general way to prevent such a stack overflow is to
enforce a maximum call stack depth instead of only disallowing directly
recursive calls.

This commit also moves that logic into `eval_call()` instead of
`eval_block()` because the recursion limit is tracked in the `Stack`,
but not all blocks are evaluated in a new stack. Incrementing the
recursion depth of the caller's stack would permanently increment that
for all future calls.

Fixes #11667

# User-Facing Changes
Any function call can now fail with `recursion_limit_reached` instead of
just directly recursive calls. Mutually-recursive calls no longer crash
nushell.

Fixes https://github.com/nushell/nushell/issues/11716

The problem is in our [record creation
API](0d518bf813/crates/nu-protocol/src/value/record.rs (L33))
which panics if the numbers of columns and values are different. I added
a safe variant that returns a `Result` and used it in the `rotate`
command.

## TODO in another PR:

Go through all `from_raw_cols_vals_unchecked()` (this includes the
`record!` macro which uses the unchecked version) and make sure that
either
a) it is guaranteed the number of cols and vals is the same, or
b) convert the call to `from_raw_cols_vals()`

Reason: Nushell should never panic.

fix exit_code handling when running a scripts with ctrlc (#11466)
# Description
Fixes: #11394

When run `^sleep 3` we have an `exit_code ListStream`, and when we press
ctrl-c, this `ListStream` will return None. But it's not expected,
because `exit_code` sender in `run_external` always send an exit code
out.

This pr is trying to fix the issue by introducing a `first_guard` into
ListStream, it will always generate a value from underlying stream if
`first_guard` is true, so it's guarantee to have at least one value to
return.

And the pr also do a little refactor, which makes use of
`ListStream::from_stream` rather than construct it manually.

Unify glob behavior on open, rm, cp-old, mv, umv, cp and du commands (#11621)
# Description
This pr is a follow up to
[#11569](https://github.com/nushell/nushell/pull/11569#issuecomment-1902279587)
> Revert the logic in https://github.com/nushell/nushell/pull/10694 and
apply the logic in this pr to mv, cp, rv will require a larger change, I
need to think how to achieve the bahavior

And sorry @bobhy for reverting some of your changes.

This pr is going to unify glob behavior on the given commands:
* open
* rm
* cp-old
* mv
* umv
* cp
* du

So they have the same behavior to `ls`, which is:
If given parameter is quoted by single quote(`'`) or double quote(`"`),
don't auto-expand the glob pattern. If not quoted, auto-expand the glob
pattern.

Fixes: #9558  Fixes: #10211 Fixes: #9310 Fixes: #10364 

# TODO
But there is one thing remains: if we give a variable to the command, it
will always auto-expand the glob pattern, e.g:
```nushell
let path = "a[123]b"
rm $path
```
I don't think it's expected. But I also think user might want to
auto-expand the glob pattern in variables.

So I'll introduce a new command called `glob escape`, then if user
doesn't want to auto-expand the glob pattern, he can just do this: `rm
($path | glob escape)`

## NOTE
This pr changes the semantic of `GlobPattern`, before this pr, it will
`expand path` after evaluated, this makes `nu_engine::glob_from` have no
chance to glob things right if a path contains glob pattern.

e.g: [#9310
](https://github.com/nushell/nushell/issues/9310#issuecomment-1886824030)
#10211

I think changing the semantic is fine, because it makes glob works if
path contains something like '*'.

It maybe a breaking change if a custom command's argument are annotated
by `: glob`.

Add into cell-path for dynamic cell-path creation (#11322)
# Description

The `cell-path` is a type that can be created statically with
`$.nested.structure.5`, but can't be created from user input. This makes
it difficult to take advantage of commands that accept a cell-path to
operate on data structures.

This PR adds `into cell-path` for dynamic cell-path creation.

`into cell-path` accepts the following input shapes:
* Bare integer (equivalent to `$.1`)
* List of strings and integers
* List of records with entries `value` and `optional`
* String (parsed into a cell-path)

## Example usage

An example of where `into cell-path` can be used is in working with `git
config --list`. The git configuration has a tree structure that maps
well to nushell records. With dynamic cell paths it is easy to convert
`git config list` to a record:

```nushell
git config --list
| lines
| parse -r '^(?<key>[^=]+)=(?<value>.*)'
| reduce --fold {} {|entry, result|
  let path = $entry.key | into cell-path

  $result
  | upsert $path {||
    $entry.value
  }
}
| select remote
```

Output:

```
╭────────┬──────────────────────────────────────────────────────────────────╮
│        │ ╭──────────┬───────────────────────────────────────────────────╮ │

╰────────┴──────────────────────────────────────────────────────────────────╯
```

## Errors

`lex()` + `parse_cell_path()` are forgiving about what is allowed in a
cell-path so it will allow what appears to be nonsense to become a
cell-path:

```nushell
let table = [["!@$%^&*" value]; [key value]]

$table | get ("!@$%^&*.0" | into cell-path)
# => key
```

But it will reject bad cell-paths:

```
❯ "a b" | into cell-path
Error: nu:🐚:cant_convert

  × Can't convert to cell-path.
   ╭─[entry #14:1:1]

This PR will allow string interpolation at parse time.

Since the actual config hasn't been loaded at parse time, this uses the
`get_config()` method on `StateWorkingSet`. So file sizes and datetimes
(I think those are the only things whose string representations depend
on the config) may be formatted differently from how users have
configured things, which may come as a surprise to some. It does seem
unlikely that anyone would be formatting file sizes or date times at
parse time. Still, something to think about if/before this PR merged.

Also, I changed the `ModuleNotFound` error to include the name of the
module.

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

Users will be able to do stuff like:

```nu
const x = [1 2 3]
const y = $"foo($x)" // foo[1, 2, 3]
```

The main use case is `use`-ing and `source`-ing files at parse time:

```nu
const file = "foo.nu"
use $"($file)"
```

If the module isn't found, you'll see an error like this:
```
Error: nu::parser::module_not_found

  × Module not found.
   ╭─[entry #3:1:1]
 1 │  use $"($file)"
   ·      ─────┬────

Although there's user-facing changes, there's probably no need to change
the docs since people probably already expect string interpolation to
work at parse time.

Edit: @kubouch pointed out that we'd need to document the fact that
stuff like file sizes and datetimes won't get formatted according to
user's runtime configs, so I'll make a PR to nushell.github.io after
this one

If something is on the boundary of a unit (e.g. 1024 bytes = 1
kibibytes), that will now be formatted as `1.0 KiB` where it used to be
formatted as `1,024 B`.

do not attempt to glob expand if the file path is wrapped in quotes (#11569)
# Description
Fixes: #11455

### For arguments which is annotated with `:path/:directory/:glob`
To fix the issue, we need to have a way to know if a path is originally
quoted during runtime. So the information needed to be added at several
levels:
* parse time (from user input to expression)
We need to add quoted information into `Expr::Filepath`,
`Expr::Directory`, `Expr::GlobPattern`
* eval time
When convert from `Expr::Filepath`, `Expr::Directory`,
`Expr::GlobPattern` to `Value::String` during runtime, we won't auto
expanded the path if it's quoted

### For `ls`
It's really special, because it accepts a `String` as a pattern, and it
generates `glob` expression inside the command itself.

So the idea behind the change is introducing a special SyntaxShape to
ls: `SyntaxShape::LsGlobPattern`. So we can track if the pattern is
originally quoted easier, and we don't auto expand the path either.

Then when constructing a glob pattern inside ls, we check if input
pattern is quoted, if so: we escape the input pattern, so we can run `ls
a[123]b`, because it's already escaped.
Finally, to accomplish the checking process, we also need to introduce a
new value type called `Value::QuotedString` to differ from
`Value::String`, it's used to generate an enum called `NuPath`, which is
finally used in `ls` function. `ls` learned from `NuPath` to know if
user input is quoted.

# User-Facing Changes

Allow plugins to receive configuration from the nushell configuration (#10955)
# Description

When nushell calls a plugin it now sends a configuration `Value` from
the nushell config under `$env.config.plugins.PLUGIN_SHORT_NAME`. This
allows plugin authors to read configuration provided by plugin users.

The `PLUGIN_SHORT_NAME` must match the registered filename after
`nu_plugin_`. If you register `target/debug/nu_plugin_config` the
`PLUGIN_NAME` will be `config` and the nushell config will loook like:

        $env.config = {
          # ...
          plugins: {
            config: [
              some
              values
            ]
          }
        }

Configuration may also use a closure which allows passing values from
`$env` to a plugin:

        $env.config = {
          # ...
          plugins: {
            config: {||
              $env.some_value
            }
          }
        }

This is a breaking change for the plugin API as the `Plugin::run()`
function now accepts a new configuration argument which is an
`&Option<Value>`. If no configuration was supplied the value is `None`.

Plugins compiled after this change should work with older nushell, and
will behave as if the configuration was not set.

Initially discussed in #10867

# User-Facing Changes

* Plugins can read configuration data stored in `$env.config.plugins`
* The plugin `CallInfo` now includes a `config` entry, existing plugins

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

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

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

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

Fix incorrect handling of boolean flags for builtin commands (#11492)
# Description
Possible fix of #11456
This PR fixes a bug where builtin commands did not respect the logic of
dynamically passed boolean flags. The reason is
[has_flag](6f59abaf43/crates/nu-protocol/src/ast/call.rs (L204C5-L212C6))
method did not evaluate and take into consideration expression used with
flag.

To address this issue a solution is proposed:
1. `has_flag` method is moved to `CallExt` and new logic to evaluate
expression and check if it is a boolean value is added
2. `has_flag_const` method is added to `CallExt` which is a constant
version of `has_flag`
3. `has_named` method is added to `Call` which is basically the old
logic of `has_flag`
4. All usages of `has_flag` in code are updated, mostly to pass
`engine_state` and `stack` to new `has_flag`. In `run_const` commands it
is replaced with `has_flag_const`. And in a few select places: parser,
`to nuon` and `into string` old logic via `has_named` is used.

# User-Facing Changes
Explicit values of boolean flags are now respected in builtin commands.

Finishes implementing https://github.com/nushell/nushell/issues/10598,
which asks for a spread operator in lists, in records, and when calling
commands.

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

This PR will allow spreading arguments to commands (both internal and
external). It will also deprecate spreading arguments automatically when
passing to external commands.

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

- Users will be able to use `...` to spread arguments to custom/builtin
commands that have rest parameters or allow unknown arguments, or to any
external command
- If a custom command doesn't have a rest parameter and it doesn't allow
unknown arguments either, the spread operator will not be allowed
- Passing lists to external commands without `...` will work for now but
will cause a deprecation warning saying that it'll stop working in 0.91
(is 2 versions enough time?)

Here's a function to help with demonstrating some behavior:
```nushell
> def foo [ a, b, c?, d?, ...rest ] { [$a $b $c $d $rest] | to nuon }
```

You can pass a list of arguments to fill in the `rest` parameter using
`...`:
```nushell
> foo 1 2 3 4 ...[5 6]
[1, 2, 3, 4, [5, 6]]
```

If you don't use `...`, the list `[5 6]` will be treated as a single
argument:

```nushell
> foo 1 2 3 4 [5 6] # Note the double [[]]
[1, 2, 3, 4, [[5, 6]]]
```

You can omit optional parameters before the spread arguments:
```nushell
> foo 1 2 3 ...[4 5] # d is omitted here
[1, 2, 3, null, [4, 5]]
```

If you have multiple lists, you can spread them all:
```nushell
> foo 1 2 3 ...[4 5] 6 7 ...[8] ...[]
[1, 2, 3, null, [4, 5, 6, 7, 8]]
```

Here's the kind of error you get when you try to spread arguments to a
command with no rest parameter:

![image](https://github.com/nushell/nushell/assets/45539777/93faceae-00eb-4e59-ac3f-17f98436e6e4)

And this is the warning you get when you pass a list to an external now
(without `...`):

Added tests to cover the following cases:
- Spreading arguments to a command that doesn't have a rest parameter
(unexpected spread argument error)
- Spreading arguments to a command that doesn't have a rest parameter
*but* there's also a missing positional argument (missing positional
error)
- Spreading arguments to a command that doesn't have a rest parameter
but does allow unknown arguments, such as `exec` (allowed)
- Spreading a list literal containing arguments of the wrong type (parse
error)
- Spreading a non-list value, both to internal and external commands
- Having named arguments in the middle of rest arguments
- `explain`ing a command call that spreads its arguments

# Examples

Suppose you have multiple tables:
```nushell
let people = [[id name age]; [0 alice 100] [1 bob 200] [2 eve 300]]
let evil_twins = [[id name age]; [0 ecila 100] [-1 bob 200] [-2 eve 300]]
```

Maybe you often find yourself needing to merge multiple tables and want
a utility to do that. You could write a function like this:
```nushell
def merge_all [ ...tables ] { $tables | reduce { |it, acc| $acc | merge $it } }
```

Then you can use it like this:
```nushell
> merge_all ...([$people $evil_twins] | each { |$it| $it | select name age })
╭───┬───────┬─────╮
│ # │ name  │ age │
├───┼───────┼─────┤
│ 0 │ ecila │ 100 │
│ 1 │ bob   │ 200 │
│ 2 │ eve   │ 300 │
╰───┴───────┴─────╯
```

Except they had duplicate columns, so now you first want to suffix every
column with a number to tell you which table the column came from. You
can make a command for that:
```nushell
def select_and_merge [ --cols: list<string>, ...tables ] {
  let renamed_tables = $tables
    | enumerate
    | each { |it|
      $it.item | select $cols | rename ...($cols | each { |col| $col + ($it.index | into string) })
    };
  merge_all ...$renamed_tables
}
```
And call it like this:
```nushell
> select_and_merge --cols [name age] $people $evil_twins
╭───┬───────┬──────┬───────┬──────╮
│ # │ name0 │ age0 │ name1 │ age1 │
├───┼───────┼──────┼───────┼──────┤
│ 0 │ alice │  100 │ ecila │  100 │
│ 1 │ bob   │  200 │ bob   │  200 │
│ 2 │ eve   │  300 │ eve   │  300 │
╰───┴───────┴──────┴───────┴──────╯
```

---

Suppose someone's made a command to search for APT packages:

```nushell
# The main command
def search-pkgs [
    --install                   # Whether to install any packages it finds
    log_level: int              # Pretend it's a good idea to make this a required positional parameter
    exclude?: list<string>      # Packages to exclude
    repositories?: list<string> # Which repositories to look in (searches in all if not given)
    ...pkgs                     # Package names to search for
] {
  { install: $install, log_level: $log_level, exclude: ($exclude | to nuon), repositories: ($repositories | to nuon), pkgs: ($pkgs | to nuon) }
}
```

It has a lot of parameters to configure it, so you might make your own
helper commands to wrap around it for specific cases. Here's one
example:
```nushell
# Only look for packages locally
def search-pkgs-local [
    --install              # Whether to install any packages it finds
    log_level: int
    exclude?: list<string> # Packages to exclude
    ...pkgs                # Package names to search for
] {
  # All required and optional positional parameters are given
  search-pkgs --install=$install $log_level [] ["<local URI or something>"] ...$pkgs
}
```
And you can run it like this:
```nushell
> search-pkgs-local --install=false 5 ...["python2.7" "vim"]
╭──────────────┬──────────────────────────────╮
│ install      │ false                        │
│ log_level    │ 5                            │
│ exclude      │ []                           │
│ repositories │ ["<local URI or something>"] │
│ pkgs         │ ["python2.7", vim]           │
╰──────────────┴──────────────────────────────╯
```

One thing I realized when writing this was that if we decide to not
allow passing optional arguments using the spread operator, then you can
(mis?)use the spread operator to skip optional parameters. Here, I
didn't want to give `exclude` explicitly, so I used a spread operator to
pass the packages to install. Without it, I would've needed to do
`search-pkgs-local --install=false 5 [] "python2.7" "vim"` (explicitly
pass `[]` (or `null`, in the general case) to `exclude`). There are
probably more idiomatic ways to do this, but I just thought it was
something interesting.

If you're a virologist of the [xkcd](https://xkcd.com/350/) kind,
another helper command you might make is this:
```nushell
# Install any packages it finds
def live-dangerously [ ...pkgs ] {
  # One optional argument was given (exclude), while another was not (repositories)
  search-pkgs 0 [] ...$pkgs --install # Flags can go after spread arguments
}
```

Running it:
```nushell
> live-dangerously "git" "*vi*" # *vi* because I don't feel like typing out vim and neovim
╭──────────────┬─────────────╮
│ install      │ true        │
│ log_level    │ 0           │
│ exclude      │ []          │
│ repositories │ null        │
│ pkgs         │ [git, *vi*] │
╰──────────────┴─────────────╯
```

Here's an example that uses the spread operator more than once within
the same command call:
```nushell
let extras = [ chrome firefox python java git ]

def search-pkgs-curated [ ...pkgs ] {
  (search-pkgs
      1
      [emacs]
      ["example.com", "foo.com"]
      vim # A must for everyone!
      ...($pkgs | filter { |p| not ($p | str contains "*") }) # Remove packages with globs
      python # Good tool to have
      ...$extras
      --install=false
      python3) # I forget, did I already put Python in extras?
}
```

Running it:
```nushell
> search-pkgs-curated "git" "*vi*"
╭──────────────┬───────────────────────────────────────────────────────────────────╮
│ install      │ false                                                             │
│ log_level    │ 1                                                                 │
│ exclude      │ [emacs]                                                           │
│ repositories │ [example.com, foo.com]                                            │
│ pkgs         │ [vim, git, python, chrome, firefox, python, java, git, "python3"] │

Remove unnecessary replace_in_variable (#11424)
# Description
`Expression::replace_in_variable` is only called in one place, and it is
called with `new_var_id` = `IN_VARIABLE_ID`. So, it ends up doing
nothing. E.g., adding `debug_assert_eq!(new_var_id, IN_VARIABLE_ID)` in
`replace_in_variable` does not trigger any panic.

Lock out new direct construction of Record (#11414)
# Description
With #11386 we don't have any nushell-internal code directly accessing
the `vals` field of `Record`, so let's make it private so everyone in
the future uses the checked ways guaranteeing matching cols/vals.

The `cols` feel has to remain pub for now as `rename` still directly
mutates this field. See #11020 for challenges for this refactor.

Deprecate --flag: bool in custom command (#11365)
# Description
While #11057 is merged, it's hard to tell the difference between
`--flag: bool` and `--flag`, and it makes user hard to read custom
commands' signature, and hard to use them correctly.

After discussion, I think we can deprecate `--flag: bool` usage, and
encourage using `--flag` instead.

# User-Facing Changes

Remove Value::MatchPattern (#11356)
# Description
`Value::MatchPattern` implies that `MatchPattern`s are first-class
values. This PR removes this case, and commands must now instead use
`Expr::MatchPattern` to extract `MatchPattern`s just like how the
`match` command does using `Expr::MatchBlock`.

Fix replacement closures for update, insert, and upsert (#11258)
# Description
This PR addresses #11204 which points out that using a closure for the
replacement value with `update`, `insert`, or `upsert` does not work for
lists.

# User-Facing Changes
- Replacement closures should now work for lists in `upsert`, `insert`,
and `update`. E.g., `[0] | update 0 {|i| $i + 1 }` now gives `[1]`
instead of an unhelpful error.
- `[1 2] | insert 4 20` no longer works. Before, this would give `[1, 2,
null, null, 20]`, but now it gives an error. This was done to match the
intended behavior in `Value::insert_data_at_cell_path`, whereas the
behavior before was probably unintentional. Following
`Value::insert_data_at_cell_path`, inserting at the end of a list is
also fine, so the valid indices for `upsert` and `insert` are
`0..=length` just like `Vec::insert` or list inserts in other languages.

# Tests + Formatting
Added tests for `upsert`, `insert`, and `update`:
- Replacement closures for lists, list streams, records, and tables
- Other list stream tests

Spread operator in record literals (#11144)
Goes towards implementing #10598, which asks for a spread operator in
lists, in records, and when calling commands (continuation of #11006,
which only implements it in lists)

# Description
This PR is for adding a spread operator that can be used when building
records. Additional functionality can be added later.

Changes:

- Previously, the `Expr::Record` variant held `(Expression, Expression)`
pairs. It now holds instances of an enum `RecordItem` (the name isn't
amazing) that allows either a key-value mapping or a spread operator.
- `...` will be treated as the spread operator when it appears before
`$`, `{`, or `(` inside records (no whitespace allowed in between) (not
implemented yet)
- The error message for duplicate columns now includes the column name
itself, because if two spread records are involved in such an error, you
can't tell which field was duplicated from the spans alone

`...` will still be treated as a normal string outside records, and even
in records, it is not treated as a spread operator when not followed
immediately by a `$`, `{`, or `(`.

# User-Facing Changes
Users will be able to use `...` when building records.

```
> let rec = { x: 1, ...{ a: 2 } }
> $rec
╭───┬───╮
│ x │ 1 │
│ a │ 2 │
╰───┴───╯
> { foo: bar, ...$rec, baz: blah }
╭─────┬──────╮
│ foo │ bar  │
│ x   │ 1    │
│ a   │ 2    │
│ baz │ blah │
╰─────┴──────╯
```
If you want to update a field of a record, you'll have to use `merge`
instead:
```
> { ...$rec, x: 5 }
Error: nu:🐚:column_defined_twice

  × Record field or table column used twice: x
   ╭─[entry #2:1:1]
 1 │  { ...$rec, x: 5 }
   ·       ──┬─  ┬
   ·         │   ╰── field redefined here
   ·         ╰── field first defined here

Support o>>, e>>, o+e>> to append output to an external file (#10764)

~~1. currently internal commands with `o+e>` redirect to a variable is
broken: `let x = "a.txt"; echo abc o+e> $x`, not sure when it was
introduced...~~
~~2. redirect stdout and stderr with append mode doesn't supported yet:

add shape ExternalResolved to show found externals via syntax highlighting in the repl (#11135)
# Description

This PR enables a new feature that shows which externals are found in
your path via the syntax highlighter as you type.

![external_resolved](https://github.com/nushell/nushell/assets/343840/e5fa91f0-6fac-485c-8afc-5711fc0ed9bc)

This idea could use some improvement where it caches the items in your
path and on some trigger, expires that cache and creates a new on. Right
now, all it does is call the `which` crate on every character you type.
This could be problematic if you have hundreds of paths in your PATH or
if some of your paths in your Path point to extraordinarily slow file
systems. WSL pointing to Windows comes to mind. Either way, I've thrown
it up here for people to try and provide feedback. I think the novelty
of showing what is valid and what isn't is pretty cool. I believe
fish-shell also does this, IIRC.

Redirect: support redirect stderr with piping stdout to next commands. (#10851)
# Description
Fixes: #10271

Given the following script:
```shell
# test.sh
echo aaaaa
echo bbbbb 1>&2
echo cc
```

This pr makes the following command possible:
```nushell
bash test.sh err> /dev/null | lines | each {|line| $line | str length}
```


## General idea behind the change:
When nushell redirect stderr message to external file
1. it take stdout of external stream, and pass this stream to next
command, so it won't block next pipeline command from running.
2. relative stderr stream are handled by `save` command

These two streams are handled separately, so we need to delegate a
thread to `save` command, or else we'll have a chance to hang nushell,
we have meet a similar before: #5625.

### One case to consider
What if we're failed to save to an external stream? (Like we don't have
a permission to save to a file)?
In this case nushell will just print a waning message, and don't stop
the following scripts from running.

# User-Facing Changes
## Before
```nushell
❯ bash test2.sh err> /dev/null | lines | each {|line| $line | str length}
aaaaa
cc
```

## After
```nushell
❯ bash test2.sh err> /dev/null | lines | each {|line| $line | str length}
╭───┬───╮
│ 0 │ 5 │
│ 1 │ 2 │
╰───┴───╯
```

BTY, after this pr, the following commands are impossible either, it's
important to make sure that the implementation doesn't introduce too
much costs:
```nushell
❯ echo a e> a.txt e> a.txt
Error:   × Can't make stderr redirection twice
   ╭─[entry #1:1:1]
 1 │ echo a e> a.txt e> a.txt

I can't see this error being used since it was introduced with #4364. I

a large merge with that PR but I can't penetrate the secrets of git to
find out where its earlier history went.

Refactor Value cell path functions to fix bugs (#11066)
# Description
Slightly refactors the cell path functions (`insert_data_at_cell_path`,
etc.) for `Value` to fix a few bugs and ensure consistent behavior.
Namely, case (in)sensitivity now applies to lazy records just like it
does for regular `Records`. Also, the insert behavior of `insert` and
`upsert` now match, alongside fixing a few related bugs described below.
Otherwise, a few places were changed to use the `Record` API.

# Tests
Added tests for two bugs:
- `{a: {}} | insert a.b.c 0`: before this PR, doesn't create the
innermost record `c`.
- `{table: [[col]; [{a: 1}], [{a: 1}]]} | insert table.col.b 2`: before
this PR, doesn't add the field `b: 2` to each row.

Add Argument::span() and Call::arguments_span() (#10983)
# Description

These make it easy to make a Span that covers an entire argument and the
span of all arguments in a Call.

Call::arguments_span() is useful for errors where a command may accept
arguments or the pipeline, but not both.

Argument::span() is useful for errors where an arguments is incompatible
with one or more other arguments.

In particular, I wish to use this to create an error for an
implementation of #9563 that either allows arguments to set limits:

```nushell
limits set RLIMIT_NOFILE --soft 255 --hard 1024
```

Or pipeline:

```nushell
{name: RLIMIT_NOFILE, soft: 255} | limits set
```

But not both:

```
❯ [{name: RLIMIT_NOFILE, soft: 255, hard: 1024}] | limits set AS --soft 5 --hard 5
Error: nu:🐚:incompatible_parameters

  × Incompatible parameters.

add "default" table theme (#11072)
# Description

This PR fixes a minor bug that prevented this command from running.
```nushell
table --list | each {|r| print ($r); print (ls | first 3 | table --theme $r)}
```
Here's the output now of the first few themes.

![image](https://github.com/nushell/nushell/assets/343840/21bc8942-5106-4b6a-8905-e90d6cb9a153)

It prevented it from running because "default" wasn't a real table
theme. Now "default" is a synonym of rounded.

Also tweaked the error message when a bad theme name is provided.

Implement Display for CellPath (#11023)
# Description
Because `CellPath::into_string` takes a borrowed `self`, I renamed it to
`to_string` to follow Rust [API
guidelines](https://rust-lang.github.io/api-guidelines/naming.html#ad-hoc-conversions-follow-as_-to_-into_-conventions-c-conv).
This then triggered the clippy lint
[inherent_to_string](https://rust-lang.github.io/rust-clippy/master/index.html#/inherent_to_string),
which is... correct! The current `CellPath::into_string` is being used
as if it were the `Display` implementation for `CellPath`.

# User-Facing Changes
Breaking API change for `nu-protocol`, since `CellPath::into_string` was
removed.

Improve case insensitivity consistency (#10884)
# Description

Add an extension trait `IgnoreCaseExt` to nu_utils which adds some case
insensitivity helpers, and use them throughout nu to improve the
handling of case insensitivity. Proper case folding is done via unicase,
which is already a dependency via mime_guess from nu-command.

In actuality a lot of code still does `to_lowercase`, because unicase
only provides immediate comparison and doesn't expose a `to_folded_case`
yet. And since we do a lot of `contains`/`starts_with`/`ends_with`, it's
not sufficient to just have `eq_ignore_case`. But if we get access in
the future, this makes us ready to use it with a change in one place.

Plus, it's clearer what the purpose is at the call site to call
`to_folded_case` instead of `to_lowercase` if it's exclusively for the
purpose of case insensitive comparison, even if it just does
`to_lowercase` still.

# User-Facing Changes

- Some commands that were supposed to be case insensitive remained only
insensitive to ASCII case (a-z), and now are case insensitive w.r.t.
non-ASCII characters as well.

- 🟢 `toolkit clippy`

Use record API in more parts of nu-protocol (#10928)
# Description

This is pretty complementary/orthogonal to @IanManske 's changes to
`Value` cellpath accessors in:
- #10925
- to a lesser extent #10926

## Steps
- Use `R.remove` in `Value.remove_data_at_cell_path`
- Pretty sound after #10875 (tests mentioned in commit message have been
removed by that)
- Update `did_you_mean` helper to use iterator
- Change `Value::columns` to return iterator
  - This is not a place of honor
- Use `Record::get` in `Value::get_data_by_key`
# User-Facing Changes
None intentional, potential edge cases on duplicated columns could
change (considered undefined behavior)

Add Record::drain to take out elements by range (#11002)
Matches the general behavior of `Vec::drain` or
`indexmap::IndexMap::drain`:
- Drop the remaining elements (implementing the unstable `keep_rest()`
would not be compatible with something like `indexmap`)
- No `AsRef<[T]>` or `Drain::as_slice()` behavior as this would make
layout assumptions.
- `Drain: DoubleEndedIterator`

Refactor and fix Config<->Value mechanism (#10896)
# Description
Our config exists both as a `Config` struct for internal consumption and
as a `Value`. The latter is exposed through `$env.config` and can be
both set and read.
Thus we have a complex bug-prone mechanism, that reads a `Value` and
then tries to plug anything where the value is unrepresentable in
`Config` with the correct state from `Config`.

The parsing involves therefore mutation of the `Value` in a nested
`Record` structure. Previously this was wholy done manually, with
indices.
To enable deletion for example, things had to be iterated over from the
back. Also things were indexed in a bunch of places. This was hard to
read and an invitation for bugs.

With #10876 we can now use `Record::retain_mut` to traverse the records,
modify anything that needs fixing, and drop invalid fields.

# Parts:

- Error messages now consistently use the correct spans pointing to the
problematic value and the paths displayed in some messages are also
aligned with the keys used for lookup.
- Reconstruction of values has been fixed for:
	- `table.padding`
	- `buffer_editor`
	- `hooks.command_not_found`
	- `datetime_format` (partial solution)
- Fix validation of `table.padding` input so value is not set (and
underflows `usize` causing `table` to run forever with negative values)
- New proper types for settings. Fully validated enums instead of
strings:
  - `config.edit_mode` -> `EditMode` 
  	- Don't fall back to vi-mode on invalid string
  - `config.table.mode` -> `TableMode`
- there is still a fall back to `rounded` if given an invalid
`TableMode` as argument to the `nu` binary
  - `config.completions.algorithm` -> `CompletionAlgorithm`
  - `config.error_style` -> `ErrorStyle`
    - don't implicitly fall back to `fancy` when given an invalid value.
- This should also shrink the size of `Config` as instead of 4x24 bytes
those fields now need only 4x1 bytes in `Config`
- Completely removed macros relying on the scope of `Value::into_config`
so we can break it up into smaller parts in the future.
- Factored everything into smaller files with the types and helpers for
particular topics.
- `NuCursorShape` now explicitly expresses the `Inherit` setting.
conversion to option only happens at the interface to `reedline`

Use Vec for Closure captures (#10940)
# Description
Changes the `captures` field in `Closure` from a `HashMap` to a `Vec`
and makes `Stack::captures_to_stack` take an owned `Vec` instead of a
borrowed `HashMap`.

This eliminates the conversion to a `Vec` inside `captures_to_stack` and
makes it possible to avoid clones altogether when using an owned
`Closure` (which is the case for most commands). Additionally, using a
`Vec` reduces the size of `Value` by 8 bytes (down to 72).

Consequences of #10841

This does not yet make the assumption that columns are always
duplicated. Follow the existing logic here

- Use saner record API in `nu-engine/src/eval.rs`
- Use checked record construction in `nu-engine/src/scope.rs`
- Use `values` iterator in `nu-engine/src/scope.rs`
- Use `columns` iterator in `nu_engine::get_columns()`
- Start using record API in `value/mod.rs`
- Use `.insert` in `eval_const.rs` Record code
- Record API for `eval_const.rs` table code

Disallow duplicated columns in table literals (#10875)
# Description
Pretty much all operations/commands in Nushell assume that the column
names/keys in a record and thus also in a table (which consists of a
list of records) are unique.
Access through a string-like cell path should refer to a single column
or key/value pair and our output through `table` will only show the last
mention of a repeated column name.

```nu
[[a a]; [1 2]]
╭─#─┬─a─╮
│ 0 │ 2 │
╰───┴───╯
```

While the record parsing already either errors with the
`ShellError::ColumnDefinedTwice` or silently overwrites the first
occurence with the second occurence, the table literal syntax `[[header
columns]; [val1 val2]]` currently still allowed the creation of tables
(and internally records with more than one entry with the same name.

This is not only confusing, but also breaks some assumptions around how
we can efficiently perform operations or in the past lead to outright
bugs (e.g. #8431 fixed by #8446).

This PR proposes to make this an error.
After this change another hole which allowed the construction of records
with non-unique column names will be plugged.

## Parts
- Fix `SE::ColumnDefinedTwice` error code
- Remove previous tests permitting duplicate columns
- Deny duplicate column in table literal eval
- Deny duplicate column in const eval
- Deny duplicate column in `from nuon`

# User-Facing Changes
`[[a a]; [1 2]]` will now return an error:

```
Error: nu:🐚:column_defined_twice

  × Record field or table column used twice
   ╭─[entry #2:1:1]
 1 │ [[a a]; [1 2]]
   ·   ┬ ┬
   ·   │ ╰── field redefined here
   ·   ╰── field first defined here
   ╰────
```

this may under rare circumstances block code from evaluating.

Furthermore this makes some NUON files invalid if they previously
contained tables with repeated column names.

# Tests + Formatting
Added tests for each of the different evaluation paths that materialize
tables.

Add Record::remove/retain/retain_mut (#10876)
# Description
While we have now a few ways to add items or iterate over the
collection, we don't have a way to cleanly remove items from `Record`.

This PR fixes that:

- Add `Record.remove()` to remove by key
- makes the assumption that keys are unique, so can not be used
universally, yet (see #10875 for an important example)
- Add naive `Record.retain()` for inplace removal
- This follows the two separate `retain`/`retain_mut` in the Rust std
library types, compared to the value-mutating `retain` in `indexmap`
- Add `Record.retain_mut()` for one-pass pruning

Continuation of #10841

Add common map-like API to nu_protocol::Record (#10841)
# Description

> Our `Record` looks like a map, quacks like a map, so let's treat it
with the API for a map

Implement common methods found on e.g. `std::collections::HashMap` or
the insertion-ordered [indexmap](https://docs.rs/indexmap).

This allows contributors to not have to worry about how to get to the
relevant items and not mess up the assumptions of a Nushell record.

## Record assumptions
- `cols` and `vals` are of equal length
- for all practical purposes, keys/columns should be unique

## End goal

The end goal of the upcoming series of PR's is to allow us to make
`cols` and `vals` private.
Then it would be possible to exchange the backing datastructure to best
fit the expected workload.
This could be statically (by finding the best balance) or dynamically by
using an `enum` of potential representations.

## Parts
- Add validating explicit part constructor
`Record::from_raw_cols_vals()`
- Add `Record.columns()` iterator
- Add `Record.values()` iterator
- Add consuming `Record.into_values()` iterator
- Add `Record.contains()` helper
- Add `Record.insert()` that respects existing keys
- Add key-based `.get()`/`.get_mut()` to `Record`
- Add `Record.get_index()` for index-based access
- Implement `Extend` for `Record` naively
- Use checked constructor in `record!` macro
- Add `Record.index_of()` to get index by key

# User-Facing Changes
None directly

# Developer facing changes
You don't have to roll your own record handling and can use a familiar
API

# Tests + Formatting
No explicit unit tests yet. Wouldn't be too tricky to validate core
properties directly.
Will be exercised by the following PRs using the new
methods/traits/iterators.

Convert more examples and tests to record! macro (#10840)
# Description
Use `record!` macro instead of defining two separate `vec!` for `cols`
and `vals` when appropriate.
This visually aligns the key with the value.
Further more you don't have to deal with the construction of `Record {
cols, vals }` so we can hide the implementation details in the future.

## State

Not covering all possible commands yet, also some tests/examples are
better expressed by creating cols and vals separately.

# User/Developer-Facing Changes
The examples and tests should read more natural. No relevant functional
change

# Bycatch

Where I noticed it I replaced usage of `Value` constructors with
`Span::test_data()` or `Span::unknown()` to the `Value::test_...`
constructors. This should make things more readable and also simplify
changes to the `Span` system in the future.

Allow filesystem commands to access files with glob metachars in name (#10694)
(squashed version of #10557, clean commit history and review thread)

Fixes #10571, also potentially: #10364, #10211, #9558, #9310,


# Description
Changes processing of arguments to filesystem commands that are source
paths or globs.
Applies to `cp, cp-old, mv, rm, du` but not `ls` (because it uses a
different globbing interface) or `glob` (because it uses a different
globbing library).

The core of the change is to lookup the argument first as a file and
only glob if it is not. That way,
a path containing glob metacharacters can be referenced without glob
quoting, though it will have to be single quoted to avoid nushell
parsing.

Before: A file path that looks like a glob is not matched by the glob
specified as a (source) argument and takes some thinking about to
access. You might say the glob pattern shadows a file with the same
spelling.
```
> ls a*

> ## Note -- a[bc]d *not* copied, and seemingly hard to access.
> cp --verbose 'a\[bc\]d' dest
Error:   × No matches found
   ╭─[entry #33:1:1]

> cp --verbose 'a[[]bc[]]d' dest
copied /home/bobhy/src/rust/work/r4/a[bc]d to /home/bobhy/src/rust/work/r4/dest/a[bc]d
```
Before_2: if file has glob metachars but isn't a valid pattern, user
gets a confusing error:

```
> touch 'a[b'
> cp 'a[b' dest
Error:   × Pattern syntax error near position 30: invalid range pattern
   ╭─[entry #13:1:1]
 1 │ cp 'a[b' dest
   ·    ──┬──
   ·      ╰── invalid pattern
   ╰────
```

After: Args to cp, mv, etc. are tried first as literal files, and only
as globs if not found to be files.

```
> cp --verbose 'a[bc]d' dest
copied /home/bobhy/src/rust/work/r4/a[bc]d to /home/bobhy/src/rust/work/r4/dest/a[bc]d
> cp --verbose '[a][bc]d' dest
copied /home/bobhy/src/rust/work/r4/abd to /home/bobhy/src/rust/work/r4/dest/abd
copied /home/bobhy/src/rust/work/r4/acd to /home/bobhy/src/rust/work/r4/dest/acd
```
After_2: file with glob metachars but invalid pattern just works.
(though Windows does not allow file name to contain `*`.).

```
> cp --verbose 'a[b' dest
copied /home/bobhy/src/rust/work/r4/a[b to /home/bobhy/src/rust/work/r4/dest/a[b
```

So, with this fix, a file shadows a glob pattern with the same spelling.
If you have such a file and really want to use the glob pattern, you
will have to glob quote some of the characters in the pattern. I think
that's less confusing to the user: if ls shows a file with a weird name,
s/he'll still be able to copy, rename or delete it.

# User-Facing Changes
Could break some existing scripts. If user happened to have a file with
a globbish name but was using a glob pattern with the same spelling, the
new version will process the file and not expand the glob.

Remove cd w/ abbreviations (#10588)
# Description

This removes the old style "cd with abbreviations" that would attempt to
guess what directory you wanted to `cd` to. This would sometimes have
false positives, so we left it off by default in the config.

In the current main, we have much-improved path completions
(https://github.com/nushell/nushell/pull/10543) so you can now do `cd
a/b<tab>` and get a much better experience (because you can see the
directory you're about to cd to). This removes the need for the previous
abbreviation system.

# User-Facing Changes

This does remove the old abbreviation system. It will likely mean that
old config files that have settings for abbreviations will now get
errors.

update: here's an example of the error you'll see:

Add kitty protocol config to nushell (#10540)
# Description

Support keyboard enhancement protocol as implemented by Kitty console,
hence Kitty protocol.

This PR enables Nushell to use keybinding that is not available before,
such as Ctrl+i (that alias to Tab) or Ctrl+e (that alias to Esc, likely
I mistaken). After this PR merged and you set `use_kitty_protocol`
enabled, if your console app support Kitty protocol (WezTerm, Kitty,
etc.) you will be able to set more fine-grained keybinding.

For Colemak users, this feature is a blessing, because some Ctrl+[hjkl]
that previously unmap-able to Ctlr+[hnei] now it is.

# User-Facing Changes

This adds `use_kitty_protocol` config which defaults to false. When set
to `true`, it enables kitty protocol on the line editor when supported,
or else it warns.

thanks to @jntrnr and their super useful tips on this PR, i learned
about the parser + evaluation, so 🙏

# Description
because we already have `null` as the value of the type `nothing` and as
a followup to the two other attempts of mine, i propose to remove the
redundant `$nothing` built-in variable 😋

this PR is the first step, deprecating `$nothing`.
a followup PR will remove it altogether and wait for 0.87 👍 

⚙️ **details**: a new `NOTHING_VARIABLE_ID = 3` has been added,
parsing `$nothing` will create it, finally a `Value::Nothing` will be
produced and a warning will be reported.

this PR already fixes the `toolkit.nu` module so that it does not throw
a bunch of warnings each time 👌

# User-Facing Changes
`$nothing` is now deprecated and will be removed in 0.87

- `nothing_fails_string`
- `nothing_fails_int`
which use a variable called `nil` now to make sure `nothing` does not

will get a "directory not found" error but the variable won't be
expanded and you won't be able to see which one of the variable was the
issue...

this PR adds this information to the error.

# User-Facing Changes
let's define a variable
```nushell
let does_not_exist = "i_do_not_exist_in_the_current_directory"
```

close #10393

PS: Maybe as a separate issue (good candidate for `GOOD FIRST ISSUE`)
add a config option to change a default `...` truncation sign to a
custom? (which would be applicable not only for `--abbreviated` but all
kind of tables)

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

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

Work for #10332

# User-Facing Changes

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

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

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

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

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

Work for #10233

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

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

We should bless a good alternative before landing this

Remove pythonic int * list behavior (#10292)
# Description
The pythonism that multiplying a scalar integer with a list results in a
repeated concatenation of the list, is ambiguous with other possible
interpretations and thus actively harmful to clear semantics in nushell.

Another possible reading of this scalar/vector product would be trying
to perform elementwise multiplication with the scalar.

Before we bless this alternative as a more reasonable design the best
course of action is to remove this pythonism.

Work related to #10233


# User-Facing Changes
Breaking change as this turns `int * list` or `list * int` into hard
errors.

remove profiling from nushell's hot loop (#10325)
# Description

This removes pipeline element profiling. This could be a useful feature,
but pipeline elements are going to be the most sensitive to in terms of
performance, as `eval_block` and how pipelines are built is one of the
hot loops inside of the eval engine.

# User-Facing Changes

Removes pipeline element profiling.

Make cursor_shape optional (#10289)
# Description
There are several cursor shape related issues #7151 #9243 #7271 #8452
#10169, you can't disable the cursor shape feature even if you comment
out the entire `cursor_shape` block in the config.nu, and even worse,
when nushell exits with an error, the cursor shape can't be restored,
that is annoying.

This PR provides an opportunity to disable setting the cursor shape.

# User-Facing Changes
If you use the default config.nu, nothing changes, but if you comment
out `cursor_shape` block or set them to `inherit`, related cursor shape
will not be set.

update format date when using %x %X %r (#10272)
# Description

Apparently some strftime formats are already localized and when you
"double localize" them, they don't work. This PR fixes that so that %x
%X %r %c don't go through the localization step.

Example: %x %X
### Before
```nushell
❯ date now | format date "%x %X %p"
09/08/2023 08 AM
```
### After
```nushell
❯ date now | format date "%x %X %p"
09/08/23 08:09:14 AM
```

I started to make one format_datetime to rule them all but one returns a
string and one returns a value. If we convert to the string, we lose the
nice error messages. If we change to value, more code has to be changed
elsewhere. So, I decided to just leave two functions.

rename the types with spaces in them to use - (#9929)
# Description
before this PR,
```nushell
> $.a.b | describe
cell path
```
which feels inconsistent with the `cell-path` type annotation, like in
```nushell
> def foo [x: cell-path] { $x | describe }; foo $.a.b
cell path
```

this PR changes the name of the "cell path" type from `cell path` to
`cell-path`

# User-Facing Changes
`cell path` is now `cell-path` in the output of `describe`.
this might be a breaking change in some scripts.

same goes with
- `list stream` -> `list-stream`
- `match pattern` -> `match-pattern`

# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
-  `toolkit test`
-  `toolkit test stdlib`

this PR adds a new `cell_path_type` test to make sure it stays equal to
`cell-path` in the future.

add plugin path when there are no signatures (#10201)
# Description

This PR adds the ability to have a `$nu.plugin-path` even when you
plugins are registered and it also should work with `nu -n --no-stdlib`.

### Before
It would give an error
```
│ plugin-path        │ IOError("Could not get plugin signature location")             │
```

### After
It returns the proper path, like this for me
```
│ plugin-path        │ /Users/fdncred/Library/Application Support/nushell/plugin.nu   │
```

Move Value to helpers, separate span call (#10121)
# Description

As part of the refactor to split spans off of Value, this moves to using
helper functions to create values, and using `.span()` instead of
matching span out of Value directly.

lot of commands to update :)

Screen reader-friendly errors (#10122)
- Hopefully closes #10120  

# Description

This PR adds a new config item, `error_style`. It will render errors in
a screen reader friendly mode when set to `"simple"`. This is done using
`miette`'s own `NarratableReportHandler`, which seamlessly replaces the
default one when needed.

Before:
```
Error: nu:🐚:external_command

  × External command failed
   ╭─[entry #2:1:1]
 1 │ doesnt exist
   · ───┬──
   ·    ╰── executable was not found
   ╰────
  help: No such file or directory (os error 2)
```

After:
```
Error: External command failed
    Diagnostic severity: error
Begin snippet for entry #4 starting at line 1, column 1

snippet line 1: doesnt exist
    label at line 1, columns 1 to 6: executable was not found
diagnostic help: No such file or directory (os error 2)
diagnostic code: nu:🐚:external_command

```

## Things to be determined

- ~Review naming. `errors.style` is not _that_ consistent with the rest
of the code. Menus use a `style` record, but table rendering mode is set
via `mode`.~ As it's a single config, we're using `error_style` for now.
- Should this kind of setting be toggable with one single parameter?
`accessibility.no_decorations` or similar, which would adjust the style
of both errors and tables accordingly.

# User-Facing Changes

No changes by default, errors will be rendered differently if
`error_style` is set to `simple`.

Spanned Value step 1: span all value cases (#10042)
# Description

This doesn't really do much that the user could see, but it helps get us
ready to do the steps of the refactor to split the span off of Value, so
that values can be spanless. This allows us to have top-level values
that can hold both a Value and a Span, without requiring that all values
have them.

We expect to see significant memory reduction by removing so many
unnecessary spans from values. For example, a table of 100,000 rows and
5 columns would have a savings of ~8megs in just spans that are almost
always duplicated.

Create Record type (#10103)
# Description
This PR creates a new `Record` type to reduce duplicate code and
possibly bugs as well. (This is an edited version of #9648.)
- `Record` implements `FromIterator` and `IntoIterator` and so can be
iterated over or collected into. For example, this helps with
conversions to and from (hash)maps. (Also, no more
`cols.iter().zip(vals)`!)
- `Record` has a `push(col, val)` function to help insure that the
number of columns is equal to the number of values. I caught a few
potential bugs thanks to this (e.g. in the `ls` command).
- Finally, this PR also adds a `record!` macro that helps simplify
record creation. It is used like so:
   ```rust
   record! {
       "key1" => some_value,
       "key2" => Value::string("text", span),
       "key3" => Value::int(optional_int.unwrap_or(0), span),
       "key4" => Value::bool(config.setting, span),
   }
   ```
Since macros hinder formatting, etc., the right hand side values should
be relatively short and sweet like the examples above.

Where possible, prefer `record!` or `.collect()` on an iterator instead
of multiple `Record::push`s, since the first two automatically set the
record capacity and do less work overall.

# User-Facing Changes
Besides the changes in `nu-protocol` the only other breaking changes are
to `nu-table::{ExpandedTable::build_map, JustTable::kv_table}`.

https://github.com/nushell/nushell/pull/9773 introduced constants to
modules and allowed to export them, but only within one level. This PR:
* allows recursive exporting of constants from all submodules
* fixes submodule imports in a list import pattern
* makes sure exported constants are actual constants

Should unblock https://github.com/nushell/nushell/pull/9678

### Example:
```nushell
module spam {
    export module eggs {
        export module bacon {
            export const viking = 'eats'
        }
    }
}

use spam 
print $spam.eggs.bacon.viking  # prints 'eats'

use spam [eggs]
print $eggs.bacon.viking  # prints 'eats'

use spam eggs bacon viking
print $viking  # prints 'eats'
```

### Limitation 1:

Considering the above `spam` module, attempting to get `eggs bacon` from
`spam` module doesn't work directly:
```nushell
use spam [ eggs bacon ]  # attempts to load `eggs`, then `bacon`
use spam [ "eggs bacon" ]  # obviously wrong name for a constant, but doesn't work also for commands
```

Workaround (for example):
```nushell
use spam eggs
use eggs [ bacon ]

print $bacon.viking  # prints 'eats'
```

I'm thinking I'll just leave it in, as you can easily work around this.
It is also a limitation of the import pattern in general, not just
constants.

### Limitation 2:

`overlay use` successfully imports the constants, but `overlay hide`
does not hide them, even though it seems to hide normal variables
successfully. This needs more investigation.

discouraged use after a stability promise.

Rename main to script name when running scripts (#9948)
# Description

This PR does three related changes:

* Keeps the originally declared name in help outputs.
* Updates the name of the commands called `main` in the user script to
the name of the script.
* Fixes the source of signature information in multiple places. This
allows scripts to have more complete help output.

Combined, the above allow the user to see the script name in the help
output of scripts, like so:


![image](https://github.com/nushell/nushell/assets/547158/741d192c-0a39-45a7-8f36-3a0dc8eeae2b)

NOTE: You still declare and call the definition `main`, so from inside
the script `main` is still the correct name. But multiple folks agreed
that seeing `main` in the script help was confusing, so this PR changes
that.

# User-Facing Changes

One potential minor breaking change is that module renames will be shown
as their originally defined name rather than the renamed name. I believe
this to be a better default.

Fix duration type to not report months or years (#9632)
<!--

- this PR should close #xxxx
- fixes #xxxx

you can also mention related issues, PRs or discussions!
-->
This PR should close #8036, #9028 (in the negative) and #9118.

Fix for #9118 is a bit pedantic.  As reported, the issue is:
```
> 2023-05-07T04:08:45+12:00 - 2019-05-10T09:59:12+12:00
3yr 12month 2day 18hr 9min 33sec
```
with this PR, you now get:
```
> 2023-05-07T04:08:45+12:00 - 2019-05-10T09:59:12+12:00
208wk 1day 18hr 9min 33sec
```
Which is strictly correct, but could still fairly be called "weird date
arithmetic".

# Description
* [x] Abide by constraint that Value::Duration remains a number of
nanoseconds with no additional fields.
* [x] `to_string()` only displays weeks .. nanoseconds. Duration doesn't
have base date to compute months or years from.
* [x] `duration | into record` likewise only has fields for weeks ..
nanoseconds.
* [x] `string | into duration` now accepts compound form of duration
to_string() (e.g '2day 3hr`, not just '2day')
* [x] `duration | into string` now works (and produces the same
representation as to_string(), which may be compound).

# User-Facing Changes
## duration -> string -> duration
Now you can "round trip" an arbitrary duration value: convert it to a
string that may include multiple time units (a "compound" value), then
convert that string back into a duration. This required changes to
`string | into duration` and the addition of `duration | into string'.
```
> 2day + 3hr
2day 3hr # the "to_string()" representation (in this case, a compound value)
> 2day + 3hr | into string
2day 3hr # string value
> 2day + 3hr | into string | into duration
2day 3hr # round-trip duration -> string -> duration
```
Note that `to nuon` and `from nuon` already round-tripped durations, but
use a different string representation.

## potentially breaking changes
* string rendering of a duration no longer has 'yr' or 'month' phrases.
* record from `duration | into record` no longer has 'year' or 'month'
fields.
The excess duration is all lumped into the `week` field, which is the
largest time unit you can
convert to without knowing the datetime from which the duration was
calculated.

Scripts that depended on month or year time units on output will need to
be changed.

### Examples
```
> 365day
52wk 1day
## Used to be: 
## 1yr

> 365day | into record
╭──────┬────╮
│ week │ 52 │
│ day  │ 1  │
│ sign │ +  │
╰──────┴────╯

## used to be:
##╭──────┬───╮
##│ year │ 1 │
##│ sign │ + │
##╰──────┴───╯

> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns)
56wk 6day 6hr 7min 8sec 9ms 10µs 11ns
## used to be:
## 1yr 1month 3day 6hr 7min 8sec 9ms 10µs 11ns
## which looks reasonable, but was actually only correct in 75% of the years and 25% of the months in the last 4 years.

> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns) | into record
╭─────────────┬────╮
│ week        │ 56 │
│ day         │ 6  │
│ hour        │ 6  │
│ minute      │ 7  │
│ second      │ 8  │
│ millisecond │ 9  │
│ microsecond │ 10 │
│ nanosecond  │ 11 │
│ sign        │ +  │
╰─────────────┴────╯
```
Strictly speaking, these changes could break an existing user script.
Losing years and months as time units is arguably a regression in
behavior.

Also, the corrected duration calculation could break an existing script
that was calibrated using the old algorithm.

Auto-expand table based on terminal width (#9934)
# Description

This PR adds back the functionality to auto-expand tables based on the
terminal width, using the logic that if the terminal is over 100 columns
to expand.

This sets the default config value in both the Rust and the default
nushell config.

To do so, it also adds back the ability for hooks to be strings of code
and not just code blocks.

Fixed a couple tests: two which assumed that the builtin display hook
didn't use a table -e, and one that assumed a hook couldn't be a string.

Make Value::columns return slice instead of cloned Vec (#9927)
# Description
This PR changes `Value::columns` to return a slice of columns instead of
cloning said columns. If the caller needs an owned copy, they can use
`slice::to_vec` or the like. This eliminates unnecessary Vec clones
(e.g., in `update cells`).

# User-Facing Changes

Nothing return type (#9935)
# Description
Fix #9928. When parsing input/output types `nothing` was incorrectly
coerced to `any`. This is addressed by changing how
[to_type](0ad1ad4277/crates/nu-protocol/src/syntax_shape.rs (L121))
method handles `nothing` syntax shape. Also `range` syntax shape is
addressed the same way.

# User-Facing Changes
`nothing` and `range` are correctly displayed in help and strictly
processed by type checking. This will break definitions that were not in
fact output nothing or range and incorrect uses of functions which input
nothing or range.

Examples of correctly defined functions:

Add an option to set header on border (style) (#9920)
fix #9796

Sorry that you've had the issues.
I've actually encountered them yesterday too (seems like they have
appeared after some refactoring in the middle) but was not able to fix
that rapid.

Created a bunch of tests.

cc: @fdncred 

Note:

This option will be certainly slower then a default ones. (could be
fixed but ... maybe later).
Maybe it shall be cited somewhere.

PS: Haven't tested on a wrapped/expanded tables.

Revert "Add an option to move header on borders" (#9908)
Reverts nushell/nushell#9796

This is just draft since we're seeing some issues with the latest fixes
to table drawing that just landed with #9796. We're hoping to get these
fixed, but if we're not able to fix them before the next release, we'll
need to revert (hence this PR, just in case we need it).

Add an option to move header on borders (#9796)
A patch to play with.
Need to make a few tests after all.

The question is what shall be done with `table.mode = none`, as it has
no borders.

```nu
$env.config.table.move_header = true
```

Relative: #8248 

After this pr, user can define const variable inside a module.

![image](https://github.com/nushell/nushell/assets/22256154/e3e03e56-c4b5-4144-a944-d1b20bec1cbd)

And user can export const variables, the following screenshot shows how
it works (it follows
https://github.com/nushell/nushell/issues/8248#issuecomment-1637442612):

![image](https://github.com/nushell/nushell/assets/22256154/b2c14760-3f27-41cc-af77-af70a4367f2a)

## About the change
1. To make module support const, we need to change `parse_module_block`
to support `const` keyword.
2. To suport export `const`, we need to make module tracking variables,
so we add `variables` attribute to `Module`
3. During eval, the const variable may not exists in `stack`, because we
don't eval `const` when we define a module, so we need to find variables
which are already registered in `engine_state`

## One more thing to note about the const value.
Consider the following code
```
module foo { const b = 3; export def bar [] { $b } }
use foo bar
const b = 4;
bar
```
The result will be 3 (which is defined in module) rather than 4. I think
it's expected behavior.

It's something like [dynamic
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Dynamic-Binding-Tips.html)
vs [lexical
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Lexical-Binding.html)
in lisp like language, and lexical binding should be right behavior
which generates more predicable result, and it doesn't introduce really
subtle bugs in nushell code.

What if user want dynamic-binding?(For example: the example code returns
`4`)
There is no way to do this, user should consider passing the value as
argument to custom command rather than const.

## TODO
- [X] adding tests for the feature.
- [X] support export const out of module to use.

Replace &Span with Span since Span is Copy (#9770)
# Description
`Span` is `Copy`, so we probably should not be passing references of
`Span` around. This PR replaces all instances of `&Span` with `Span`,
copying spans where necessary.

# User-Facing Changes
This alters some public functions to take `Span` instead of `&Span` as
input. Namely, `EngineState::get_span_contents`,
`nu_protocol::extract_value`, a bunch of the math commands, and
`Gstat::gstat`.

Remove Signature.vectorizes_over_list entirely (#9777)
# Description
With the current typechecking logic this property has no effect.
It was only used in the example testing, and provided some indication of
this vectorizing property.
With #9742 all commands that previously declared it have explicit list
signatures. If we want to get it back in the future we can reconstruct
it from the signature.

Simplifies the example testing a bit.

# User-Facing Changes
Causes a breaking change for plugins that previously declared it. While
this causes a compile fail, this was already broken by our more
stringent type checking.
This will be a good reminder for plugin authors to update their
signature as well to reflect the more stringent type checking.

Abort type determination for List early (#9779)
# Description
If we reach the conclusion that the fields of a list are of `Type::Any`
there is no need to continue as the type will remain `Type::Any`

This should improve runtimes of `Value.get_type()` for lists with mixed
types.

None, a speedup in some cases.

Add functions for each Value case (#9736)
# Description
This PR ensures functions exist to extract and create each and every
`Value` case. It also renames `Value::boolean` to `Value::bool` to match
`Value::test_bool`, `Value::as_bool`, and `Value::Bool`. Similarly,
`Value::as_integer` was renamed to `Value::as_int` to be consistent with
`Value::int`, `Value::test_int`, and `Value::Int`. These two renames can
be undone if necessary.

# User-Facing Changes
No user facing changes, but two public functions were renamed which may
affect downstream dependents.
