Remove the NU_DISABLE_IR option (#14293)
# Description

Removes the `NU_DISABLE_IR` option and some code related to evaluating
blocks with the AST
evaluator.

Does not entirely remove the AST evaluator yet. We still have some
dependencies on expression
evaluation in a few minor places which will take a little bit of effort
to fix.

Also changes `debug profile` to always include instructions, because the
output is a little
confusing otherwise, and removes the different options for
instructions/exprs.

# User-Facing Changes

- `NU_DISABLE_IR` no longer has any effect, and is removed. There is no
way to use the AST
  evaluator.
- `debug profile` no longer has `--exprs`, `--instructions` options.
- `debug profile` lists `pc` and `instruction` columns by default now.

# Tests + Formatting

Eval tests fixed to only use IR.

# After Submitting

- [ ] release notes
- [ ] finish removing AST evaluator, come up with solutions for the
expression evaluation.

This PR fixes the quoting and escaping of column names in `to nuon`.
Before the PR, column names with quotes inside them would get quoted,
but not escaped:

```nushell
> { 'a"b': 2 } | to nuon
{ "a"b": 2 }

> { 'a"b': 2 } | to nuon | from nuon
Error:   × error when loading nuon text

   ╰────
```

After this PR, the quote is escaped properly:

```nushell
> { 'a"b': 2 } | to nuon
{ "a\"b": 2 }

> { 'a"b': 2 } | to nuon | from nuon
╭─────┬───╮
│ a"b │ 2 │
╰─────┴───╯

> [['a"b']; [2] [3]] | to nuon
[["a\"b"]; [2], [3]]

> [['a"b']; [2] [3]] | to nuon | from nuon
╭─────╮
│ a"b │
├─────┤
│   2 │
│   3 │
╰─────╯
```

The cause of the issue was that `to nuon` simply wrapped column names in
`'"'` instead of calling `escape_quote_string`.

As part of this change, I also moved the functions related to quoting
(`needs_quoting` and `escape_quote_string`) into `nu-utils`, since
previously they were defined in very ad-hoc places (and, in the case of
`escape_quote_string`, it was defined multiple times with the same
body!).

# User-Facing Changes

# Description

This is mainly https://github.com/nushell/nushell/pull/13450 (which got
reverted). Additionally:
 - always clear IDs on import, disallow specifying IDs when piping
 - added extra tests
 - create backup of the history

# User-Facing Changes

New command: `history import`

Add the history import command (#13450)
# Description

Adds a simple command for importing history between different file
formats. It essentially opens the history of the format opposite of the
one currently selected, and writes new items to the current history. It
also supports piping, because why not.

As more history backends are added, this may need to be extended -
either make the source explicit, or autodetect based on existing files.
For now it should be good though.

This should replace some of the work-arounds mentioned in
https://github.com/nushell/nushell/issues/9403.

I suspect it will have at least one problem:
https://github.com/nushell/nushell/issues/9403 mentions the history file
might be locked on Windows. That being said, I was able to successfully
import plaintext history into sqlite on Linux, so the command should be
functional at least in that environment.

The locking issue could be solved later by plumbing reedline history to
the command (so that it doesn't have to reopen it). But first, I want to
get some general input on the approach.

# User-Facing Changes
New command: `history import`

# Tests + Formatting
There's a unit test, but didn't add a proper integration test yet. Not
entirely sure how - I see there's the `nu!` macro for that, but not sure
how feasible it's to inspect history generated by commands ran that way.
Could use a hint.2

Respect user-defined $env.NU_LOG_FORMAT and $env.NU_LOG_DATE_FORMAT (#13692)
Fixes nushell/nushell#13689

# Description

Respect user-defined `$env.NU_LOG_FORMAT` and `$env.NU_LOG_DATE_FORMAT`

Additionally I fixed `nu_with_std!()` macro (it was not working
correctly)

# User-Facing Changes

Users now may set `$env.NU_LOG_FORMAT` and `$env.NU_LOG_DATE_FORMAT` in
`env.nu` and it will work even if `use std` is used after that.

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

This PR adds an internal representation language to Nushell, offering an
alternative evaluator based on simple instructions, stream-containing
registers, and indexed control flow. The number of registers required is
determined statically at compile-time, and the fixed size required is
allocated upon entering the block.

Each instruction is associated with a span, which makes going backwards
from IR instructions to source code very easy.

Motivations for IR:

1. **Performance.** By simplifying the evaluation path and making it
more cache-friendly and branch predictor-friendly, code that does a lot
of computation in Nushell itself can be sped up a decent bit. Because
the IR is fairly easy to reason about, we can also implement
optimization passes in the future to eliminate and simplify code.
2. **Correctness.** The instructions mostly have very simple and
easily-specified behavior, so hopefully engine changes are a little bit
easier to reason about, and they can be specified in a more formal way
at some point. I have made an effort to document each of the
instructions in the docs for the enum itself in a reasonably specific
way. Some of the errors that would have happened during evaluation
before are now moved to the compilation step instead, because they don't
make sense to check during evaluation.
3. **As an intermediate target.** This is a good step for us to bring
the [`new-nu-parser`](https://github.com/nushell/new-nu-parser) in at
some point, as code generated from new AST can be directly compared to
code generated from old AST. If the IR code is functionally equivalent,
it will behave the exact same way.
4. **Debugging.** With a little bit more work, we can probably give
control over advancing the virtual machine that `IrBlock`s run on to
some sort of external driver, making things like breakpoints and single
stepping possible. Tools like `view ir` and [`explore
ir`](https://github.com/devyn/nu_plugin_explore_ir) make it easier than
before to see what exactly is going on with your Nushell code.

The goal is to eventually replace the AST evaluator entirely, once we're
sure it's working just as well. You can help dogfood this by running
Nushell with `$env.NU_USE_IR` set to some value. The environment
variable is checked when Nushell starts, so config runs with IR, or it
can also be set on a line at the REPL to change it dynamically. It is
also checked when running `do` in case within a script you want to just
run a specific piece of code with or without IR.

# Example

```nushell
view ir { |data|
  mut sum = 0
  for n in $data {
    $sum += $n
  }
  $sum
}
```
  
```gas
# 3 registers, 19 instructions, 0 bytes of data
   0: load-literal           %0, int(0)
   1: store-variable         var 904, %0 # let
   2: drain                  %0
   3: drop                   %0
   4: load-variable          %1, var 903
   5: iterate                %0, %1, end 15 # for, label(1), from(14:)
   6: store-variable         var 905, %0
   7: load-variable          %0, var 904
   8: load-variable          %2, var 905
   9: binary-op              %0, Math(Plus), %2
  10: span                   %0
  11: store-variable         var 904, %0
  12: load-literal           %0, nothing
  13: drain                  %0
  14: jump                   5
  15: drop                   %0          # label(0), from(5:)
  16: drain                  %0
  17: load-variable          %0, var 904
  18: return                 %0
```

# Benchmarks

All benchmarks run on a base model Mac Mini M1.

## Iterative Fibonacci sequence

This is about as best case as possible, making use of the much faster
control flow. Most code will not experience a speed improvement nearly
this large.

```nushell
def fib [n: int] {
  mut a = 0
  mut b = 1
  for _ in 2..=$n {
    let c = $a + $b
    $a = $b
    $b = $c
  }
  $b
}
use std bench
bench { 0..50 | each { |n| fib $n } }

[random-bytes.nu](https://github.com/nushell/nu_scripts/blob/main/benchmarks/random-bytes.nu)

I got pretty random results out of this benchmark so I decided not to
include it. Not clear why.

# User-Facing Changes
- IR compilation errors may appear even if the user isn't evaluating
with IR.
- IR evaluation can be enabled by setting the `NU_USE_IR` environment
variable to any value.
- New command `view ir` pretty-prints the IR for a block, and `view ir
--json` can be piped into an external tool like [`explore
ir`](https://github.com/devyn/nu_plugin_explore_ir).

# Tests + Formatting
All tests are passing with `NU_USE_IR=1`, and I've added some more eval
tests to compare the results for some very core operations. I will
probably want to add some more so we don't have to always check
`NU_USE_IR=1 toolkit test --workspace` on a regular basis.

- [ ] further documentation of instructions?

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

We've had a lot of different issues and PRs related to arg handling with
externals since the rewrite of `run-external` in #12921:

- #12950
- #12955
- #13000
- #13001
- #13021
- #13027
- #13028
- #13073

Many of these are caused by the argument handling of external calls and
`run-external` being very special and involving the parser handing
quoted strings over to `run-external` so that it knows whether to expand
tildes and globs and so on. This is really unusual and also makes it
harder to use `run-external`, and also harder to understand it (and
probably is part of the reason why it was rewritten in the first place).

This PR moves a lot more of that work over to the parser, so that by the
time `run-external` gets it, it's dealing with much more normal Nushell
values. In particular:

- Unquoted strings are handled as globs with no expand
- The unescaped-but-quoted handling of strings was removed, and the
parser constructs normal looking strings instead, removing internal
quotes so that `run-external` doesn't have to do it
- Bare word interpolation is now supported and expansion is done in this
case
- Expressions typed as `Glob` containing `Expr::StringInterpolation` now
produce `Value::Glob` instead, with the quoted status from the expr
passed through so we know if it was a bare word
- Bare word interpolation for values typed as `glob` now possible, but
not implemented
- Because expansion is now triggered by `Value::Glob(_, false)` instead
of looking at the expr, externals now support glob types

# User-Facing Changes

- Bare word interpolation works for external command options, and
otherwise embedded in other strings:
  ```nushell
  ^echo --foo=(2 + 2) # prints --foo=4
  ^echo -foo=$"(2 + 2)" # prints -foo=4
  ^echo foo="(2 + 2)" # prints (no interpolation!) foo=(2 + 2)
  ^echo foo,(2 + 2),bar # prints foo,4,bar
  ```

- Bare word interpolation expands for external command head/args:
  ```nushell
  let name = "exa"
  ~/.cargo/bin/($name) # this works, and expands the tilde
  ^$"~/.cargo/bin/($name)" # this doesn't expand the tilde
  ^echo ~/($name)/* # this glob is expanded
  ^echo $"~/($name)/*" # this isn't expanded
  ```

- Ndots are now supported for the head of an external command
(`^.../foo` works)

- Glob values are now supported for head/args of an external command,
and expanded appropriately:
  ```nushell
  ^("~/.cargo/bin/exa" | into glob) # the tilde is expanded
  ^echo ("*.txt" | into glob) # this glob is expanded
  ```

- `run-external` now works more like any other command, without
expecting a special call convention
  for its args:
  ```nushell
  run-external echo "'foo'"
  # before PR: 'foo'
  # after PR:  foo
  run-external echo "*.txt"
  # before PR: (glob is expanded)
  # after PR:  *.txt
  ```

# Tests + Formatting
Lots of tests added and cleaned up. Some tests that weren't active on
Windows changed to use `nu --testbin cococo` so that they can work.
Added a test for Linux only to make sure tilde expansion of commands
works, because changing `HOME` there causes `~` to reliably change.

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

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

cc @abusch

# User-Facing Changes

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

# Tests + Formatting

Surprisingly, all of the tests pass, including in small windows! I only
had to make one change to a test for `error make` which was looking for
the box drawing characters miette uses to determine whether the span
label was showing up - but the plain error style output is even better
and easier to match on, so this test is actually more specific now.

Msgpack commands (#12664)
# Description

I thought about bringing `nu_plugin_msgpack` in, but that is MPL with a
clause that prevents other licenses, so rather than adapt that code I
decided to take a crack at just doing it straight from `rmp` to `Value`
without any `rmpv` in the middle. It seems like it's probably faster,
though I can't say for sure how much with the plugin overhead.

@IanManske I started on a `Read` implementation for `RawStream` but just
specialized to `from msgpack` here, but I'm thinking after release maybe
we can polish it up and make it a real one. It works!

# User-Facing Changes
New commands:

- `from msgpack`
- `from msgpackz`
- `to msgpack`
- `to msgpackz`

# Tests + Formatting
Pretty thorough tests added for the format deserialization, with a
roundtrip for serialization. Some example tests too for both `from
msgpack` and `to msgpack`.

Deprecate register and add plugin use (#12607)
# Description

Adds a new keyword, `plugin use`. Unlike `register`, this merely loads
the signatures from the plugin cache file. The file is configurable with
the `--plugin-config` option either to `nu` or to `plugin use` itself,
just like the other `plugin` family of commands. At the REPL, one might
do this to replace `register`:

```nushell
> plugin add ~/.cargo/bin/nu_plugin_foo
> plugin use foo
```

This will not work in a script, because `plugin use` is a keyword and
`plugin add` does not evaluate at parse time (intentionally). This means
we no longer run random binaries during parse.

The `--plugins` option has been added to allow running `nu` with certain
plugins in one step. This is used especially for the `nu_with_plugins!`
test macro, but I'd imagine is generally useful. The only weird quirk is
that it has to be a list, and we don't really do this for any of our
other CLI args at the moment.

`register` now prints a deprecation parse warning.

This should fix #11923, as we now have a complete alternative to
`register`.

# User-Facing Changes

- Add `plugin use` command
- Deprecate `register`
- Add `--plugins` option to `nu` to replace a common use of `register`

# Tests + Formatting

I think I've tested it thoroughly enough and every existing test passes.
Testing nu CLI options and alternate config files is a little hairy and
I wish there were some more generic helpers for this, so this will go on
my TODO list for refactoring.

Overhaul the plugin cache file with a new msgpack+brotli format (#12579)
# Description

- Plugin signatures are now saved to `plugin.msgpackz`, which is
brotli-compressed MessagePack.
- The file is updated incrementally, rather than writing all plugin
commands in the engine every time.
- The file always contains the result of the `Signature` call to the
plugin, even if commands were removed.
- Invalid data for a particular plugin just causes an error to be
reported, but the rest of the plugins can still be parsed

# User-Facing Changes

- The plugin file has a different filename, and it's not a nushell
script.
- The default `plugin.nu` file will be automatically migrated the first
time, but not other plugin config files.
- We don't currently provide any utilities that could help edit this
file, beyond `plugin add` and `plugin rm`
  - `from msgpackz`, `to msgpackz` could also help
- New commands: `plugin add`, `plugin rm`

# Tests + Formatting

Tests added for the format and for the invalid handling.

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`

Local socket mode and foreground terminal control for plugins (#12448)
# Description

Adds support for running plugins using local socket communication
instead of stdio. This will be an optional thing that not all plugins
have to support.

This frees up stdio for use to make plugins that use stdio to create
terminal UIs, cc @amtoine, @fdncred.

This uses the [`interprocess`](https://crates.io/crates/interprocess)
crate (298 stars, MIT license, actively maintained), which seems to be
the best option for cross-platform local socket support in Rust. On
Windows, a local socket name is provided. On Unixes, it's a path. The
socket name is kept to a relatively small size because some operating
systems have pretty strict limits on the whole path (~100 chars), so on
macOS for example we prefer `/tmp/nu.{pid}.{hash64}.sock` where the hash
includes the plugin filename and timestamp to be unique enough.

This also adds an API for moving plugins in and out of the foreground
group, which is relevant for Unixes where direct terminal control
depends on that.

TODO:

- [x] Generate local socket path according to OS conventions
- [x] Add support for passing `--local-socket` to the plugin executable
instead of `--stdio`, and communicating over that instead
- [x] Test plugins that were broken, including
[amtoine/nu_plugin_explore](https://github.com/amtoine/nu_plugin_explore)
- [x] Automatically upgrade to using local sockets when supported,
falling back if it doesn't work, transparently to the user without any
visible error messages
  - Added protocol feature: `LocalSocket`
- [x] Reset preferred mode to `None` on `register`
- [x] Allow plugins to detect whether they're running on a local socket
and can use stdio freely, so that TUI plugins can just produce an error
message otherwise
  - Implemented via `EngineInterface::is_using_stdio()`
- [x] Clean up foreground state when plugin command exits on the engine
side too, not just whole plugin
- [x] Make sure tests for failure cases work as intended
  - `nu_plugin_stress_internals` added

# User-Facing Changes
- TUI plugins work
- Non-Rust plugins could optionally choose to use this
- This might behave differently, so will need to test it carefully
across different operating systems

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

Isolate tests from user config (#12437)
# Description
This is an attempt to isolate the unit tests from whatever might be in
the user's config. If the
user's config is broken in some way or incompatible with this version
(for example, especially if
there are plugins that aren't built for this version), tests can
spuriously fail.

This makes tests more reliably pass the same way they would on CI even
if the user has config, and
should also make them run faster.

I think this is _good enough_, but I still think we should have a
specific config dir env variable for nushell specifically (rather than
having to use `XDG_CONFIG_HOME`, which would mess with other things) and
then we can just have `nu-test-support` set that to a temporary dir
containing the shipped default config files.

Unfortunally it's not easy to handle for [try
fold](https://rust-lang.github.io/rust-clippy/master/index.html#/manual_try_fold)
warning in `start command`

Refer to known issue:
> This lint doesn’t take into account whether a function does something
on the failure case, i.e., whether short-circuiting will affect
behavior. Refactoring to try_fold is not desirable in those cases.

That's the case for our code, which does something on the failure case.

So this pr is making a little refactor on `try_commands`.

Simplify nu! test macros. (#10403)
# Description
Unify the logic between `nu!` and `nu_with_std!`.
The inner code actually does not contain any variadic components. So it
can safely be abstracted into a function.
Similarly simplify the variadic to an array in `nu_with_plugin!`

This also seems to simplify the codegen for tests.

Comparing the size of the `/target/debug` folder after running:

```sh
cargo clean --profile dev
cargo build --workspace --tests
```

With this branch a reduction from `8.9GB` to `8.7GB`

# Description

I've been investigating the [issue
mentioned](https://github.com/nushell/nushell/pull/9976#issuecomment-1673290467)
in my prev pr and I've found that plugin.nu file that is used to cache
plugins signatures gets overwritten on every nushell startup and that
may actually mess up with the file content if 2 or more instances of
nushell will run simultaneously.

To reproduce:
1. register at least 2 plugins in your local nushell
2. remember how many entries you have in plugin.nu with `open
$nu.plugin-path | find nu_plugin`
3. run 
    - either `cargo test` inside nushell repo
- or run smth like this `1..100 | par-each {|it| $"(random integer
1..100)ms" | into duration | sleep $in; nu -c "$nu.plugin-path"}` to
simulate parallel access. This approach is not so reliable to reproduce
as running test but still a good point that it may effect users actually
4. validate that your `plugin.nu` file was stripped

# Solution

In this pr I've refactored the code of handling the `register` command
to minimize code duplications and make sure that overwrite of
`plugin.nu` file is happen only when user calls the command and not on
nu startup

Another option would be to use temp `plugin.nu` when running tests, but
as the issue actually can affect users I've decided to prevent
unnecessary writing at all. Although having isolated `plugin.nu` still
worth of doing

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
It changes the behaviour actually as the call `register <plugin>
<signature>` now doesn't updates `plugin.nu` and just reads signatures
to the memory. But as I understand that kind of call with explicit
signature is meant to use only by nushell itself in the `plugin.nu` file
only. I've asked about it in
[discord](https://discordapp.com/channels/601130461678272522/615962413203718156/1140013448915325018)

Actually, I think the way plugins are stored might be reworked to
prevent or mitigate possible issues further:
- problem with writing to file may still arise if we try to register in
parallel as several instances will write to the same file so the lock
for the file might be required
- using additional parameters to command like `register` to implement
some internal logic could be misleading to the users
- `register` call actually affects global state of nushell that sounds a
little bit inconsistent with immutability and isolation of other parts
of the nu. See issues

Put a lock around cargo build invocations for plugin tests (#8333)
I think this _might_ fix the issues we've been seeing with plugin tests.

In a nutshell, the plugin tests run `cargo build` to ensure that plugins
have been built:
f6ca62384e/crates/nu-test-support/src/commands.rs (L6)

This PR adds a mutex to ensure that we're never running `cargo build`
concurrently. It also uses an atomic bool to signal when plugins have
already been built, so we can avoid invoking `cargo build` multiple
times unnecessarily.

I can't be certain yet, but I'm guessing the macOS CI problems we've
been seeing come from plugin tests clobbering each other (something
like: test 1 builds the `foo` plugin, then test2 invokes `cargo build`
again and deletes the `foo` plugin from disk).

Move some from xxx commands to plugin (#7942)
# Description

From nushell 0.8 philosophy:
https://github.com/nushell/nushell.github.io/blob/main/contributor-book/philosophy_0_80.md#core-categories

> The following categories should be moved to plugins:
Uncommon format support

So this pr is trying to move following commands to plugin:
- [X] from eml
- [x] from ics
- [x] from ini
- [x] from vcf

And we can have a new plugin handles for these formatting, currently
it's implemented here:

https://github.com/WindSoilder/nu_plugin_format

The command usage should be the same to original command.

If it's ok, the plugin can support more formats like
[parquet](https://github.com/fdncred/nu_plugin_from_parquet), or [EDN
format](https://github.com/nushell/nushell/issues/6415), or something
else.

Just create a draft pr to show what's the blueprint looks like, and is
it a good direction to move forward?

Make config.filesize_format/config.filesize_metric conflict resolution consistent (#7410)
# Description

Currently, `filesize_format`/`filesize_metric` conflicts are resolved as
follows: if the `filesize_format` ends in "ib", then that overrides
`filesize_metric`, otherwise, `filesize_metric` overrides
`filesize_format`. This removes this difficult-to-predict asymmetric
behaviour, and makes it so that `filesize_metric` always overrides
`filesize_format`.

This also adds tests for `$env.config.filesize.format` and
`$env.config.filesize.metric` values.

REMINDER: `filesize_metric` means "increments of 1000", and refers to
KB-MB-GB-TB etc.

Use nu-path correctly in nu! test macro to make dev-dependency transitive (#7488)
## Fix `nu-path` usage in `nu!` testing macro

The `nu-path` crate needs to be properly re-exported so the generated
code is valid if `nu-path` is not present among the dependencies of the
using crate.

Usage of crates in `macro_rules!` macros has to follow the
`$crate::symbol_in_crate` path pattern (With an absolute path-spec also
for macros defined in submodules)

## Move `nu-test-support` to devdeps in `nu-protocol`

Also remove the now unnecessary direct dependency on `nu-path`.
`nu!` macro had to be changed to make it a proper transitive dependency.

Add decimals to int when using into string --decimals (#6085)
* Add decimals to int when using `into string --decimals`

* Add tests for `into string` when converting int with `--decimals`

* Apply formatting

* Merge `into_str` test files

* Comment out unused code and add TODOs

* Use decimal separator depending on system locale

* Add test helper to run closure in different locale

* Add tests for int-to-string conversion using different locales

* Add utils function to get system locale

* Add panic message when locking mutex fails

* Catch and resume panic later to prevent Mutex poisoning when test fails

* Move test to `nu-test-support` to keep `nu-utils` free of `nu-*` dependencies

See https://github.com/nushell/nushell/pull/6085#issuecomment-1193131694

* Rename test support fn `with_fake_locale` to `with_locale_override`

* Move `get_system_locale()` to `locale` module

* Allow overriding locale with special env variable (when not in release)

* Use special env var to override locale during testing

* Allow callback to return a value in `with_locale_override()`

* Allow multiple options in `nu!` macro

* Allow to set locale as `nu!` macro option

* Use new `locale` option of `nu!` macro instead of `with_locale_override`

Using the `locale` options does not lock the `LOCALE_OVERRIDE_MUTEX`
mutex in `nu-test-support::locale_override` but instead calls the `nu`
command directly with the `NU_LOCALE_OVERRIDE` environment variable.
This allows for parallel test excecution.

* Fix: Add option identifier for `cwd` in usage of `nu!` macro

* Rely on `Display` trait for formatting `nu!` macro command

- Removed the `DisplayPath` trait
- Implement `Display` for `AbsolutePath`, `RelativePath` and
  `AbsoluteFile`

* Default to locale `en_US.UTF-8` for tests when using `nu!` macro

* Add doc comment to `nu!` macro

* Format code using `cargo fmt --all`

* Pass function directly instead of wrapping the call in a closure

Restore nu_with_plugins test macro (#6065)
* Updated nu_with_plugins to handle new nushell

- Now it requires the plugin format and name to be passed in, because
  we can't really guess the format
- It calls `register` with format and plugin path
- It creates a temporary folder and in it an empty temporary plugin.nu
  so that the tests don't conflict with each other or with local copy of
  plugin.nu
- Instead of passing the commands via stdin it passes them via the new
  --commands command line argument

* Rename path to command for clarity

* Enable core_inc tests

Remove deprecated inc feature and replace with new plugin feature

* Update core_inc tests for new nu_with_plugins syntax

* Rework core_inc::can_only_apply_one

The new inc plugin doesn't error if passed more than one but instead
chooses the highest increment

* Gate all plugin tests behind feature = "plugin" instead of one by one

* Remove format!-like behavior from nu_with_plugins

nu_with_plugins had format!-like behavior where it would allow calls
such as this:
```rs
nu_with_plugins!(
  cwd: "dir/",
  "open {} | get {}",
  "Cargo.toml",
  "package.version"
)
```
And although nifty it seems to have never been used before and the same
can be achieved with a format! like so:
```rs
nu_with_plugins!(
  cwd: "dir/",
  format!("open {} | get {}", "Cargo.toml", "package.version")
)
```
So I am removing it to keep the complexity of the macro in check

* Add multi-plugin support to nu_with_plugins

Useful for testing interactions between plugins

* Alternative 1: run `cargo build` inside of tests

* Handle Windows by canonicalizing paths and add .exe

One VM install later and lots of learning about how command line
arguments work and here we are

Test support fixes (#4517)
* Fix failing pipeline()

The `skip(1)` was there likely to remove the welcome message.

* Fix typo

* Fix nu! test macro to enter cwd correctly

Nushell's current working directory is determined primarily by the PWD
environment variable.

nu-path crate refactor (#3730)
* Resolve rebase artifacts

* Remove leftover dependencies on removed feature

* Remove unnecessary 'pub'

* Start taking notes and fooling around

* Split canonicalize to two versions; Add TODOs

One that takes `relative_to` and one that doesn't.
More TODO notes.

* Merge absolutize to and rename resolve_dots

* Add custom absolutize fn and use it in path expand

* Convert a couple of dunce::canonicalize to ours

* Update nu-path description

* Replace all canonicalize with nu-path version

* Remove leftover dunce dependencies

* Fix broken autocd with trailing slash

Trailing slash is preserved *only* in paths that do not contain "." or
"..". This should be fixed in the future to cover all paths but for now
it at least covers basic cases.

* Use dunce::canonicalize for canonicalizing

* Alow cd recovery from non-existent cwd

* Disable removed canonicalize functionality tests

Remove unused import

* Break down nu-path into separate modules

* Remove unused public imports

* Remove abundant cow mapping

* Fix clippy warning

* Reformulate old canonicalize tests to expand_path

They wouldn't work with the new canonicalize.

* Canonicalize also ~ and ndots; Unify path joining

Also, add doc comments in nu_path::expansions.

* Add comment

* Avoid expanding ndots if path is not valid UTF-8

With this change, no lossy path->string conversion should happen in the
nu-path crate.

* Fmt

* Slight expand_tilde refactor; Add doc comments

* Start nu-path integration tests

* Add tests TODO

* Fix docstring typo

* Fix some doc strings

* Add README for nu-path crate

* Add a couple of canonicalize tests

* Add nu-path integration tests

* Add trim trailing slashes tests

* Update nu-path dependency

* Remove unused import

* Regenerate lockfile

History, more test coverage improvements, and refactorings. (#3217)
Improvements overall to Nu. Also among the changes here, we can also be more confident towards incorporating `3041`. End to end tests for checking envs properly exported to externals is not added here (since it's in the other PR)

A few things added in this PR (probably forgetting some too)

* no writes happen to history during test runs.
* environment syncing end to end coverage added.
* clean up / refactorings few areas.
* testing API for finer control (can write tests passing more than one pipeline)
* can pass environment variables in tests that nu will inherit when running.

* No longer needed.

* no longer under a module. No need to use super.

Extract .nu-env tests and more granularity (#3078)
The autoenv logic mutates environment variables in the running session as
it operates and decides what to do for trusted directories containing `.nu-env`
files. Few of the ways to interact with it were all in a single test function.

We separate out all the ways that were done in the single test function to document
 it better. This will greatly help once we start refactoring our way out from setting
 environment variables this way to just setting them to `Scope`.

This is part of an on-going effort to keep variables (`PATH` and `ENV`)
in our `Scope` and rely on it for everything related to variables.

We expect to move away from setting (`std::*`) envrironment variables in the current
running process. This is non-trivial since we need to handle cases from vars
coming in from the outside world, prioritize, and also compare to the ones
we have both stored in memory and in configuration files.

Also to send out our in-memory (in `Scope`) variables properly to external
programs once we no longer rely on `std::env` vars from the running process.

Core nu plugin load capability. (#2544)
We introduce the `plugin` nu sub command (`nu plugin`) with basic plugin
loading support. We can choose to load plugins from a directory. Originally
introduced to make integration tests faster (by not loading any plugins on startup at all)
but `nu plugin --load some_path ; test_pipeline_that_uses_plugins_just_loaded` does not see it.

Therefore, a `nu_with_plugins!` macro for tests was introduced on top of nu`s `--skip-plugins`
switch executable which is set to true when running the integration tests that use the `nu!` macro now..
