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.

# After Submitting
- [ ] release notes
- [ ] further documentation of instructions?
- [ ] post-release: publish `nu_plugin_explore_ir`

Add and use new Signals struct (#13314)
# Description
This PR introduces a new `Signals` struct to replace our adhoc passing
around of `ctrlc: Option<Arc<AtomicBool>>`. Doing so has a few benefits:
- We can better enforce when/where resetting or triggering an interrupt
is allowed.
- Consolidates `nu_utils::ctrl_c::was_pressed` and other ad-hoc
re-implementations into a single place: `Signals::check`.
- This allows us to add other types of signals later if we want. E.g.,
exiting or suspension.
- Similarly, we can more easily change the underlying implementation if
we need to in the future.
- Places that used to have a `ctrlc` of `None` now use
`Signals::empty()`, so we can double check these usages for correctness
in the future.

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

fixed #12699

When bare dates or naive times are specified in toml files, `from toml`
returns invalid dates or times.
This PR fixes the problem to correctly handle toml datetime.

The current version command returns the default datetime
(`chrono::DateTime::default()`) if the datetime parse fails. However, I
felt that this behavior was a bit unfriendly, so I changed it to return
`Value::string`.

# User-Facing Changes

The command returns a date with default time and timezone if a bare date
is specified.

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

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

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

~/Development/nushell> "tm = 11:00:00" | from toml | get tm
11:00:00

```

# Tests + Formatting

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

Preserve attributes on external ByteStreams (#13305)
# Description

Bug fix: `PipelineData::check_external_failed()` was not preserving the
original `type_` and `known_size` attributes of the stream passed in for
streams that come from children, so `external-command | into binary` did
not work properly and always ended up still being unknown type.

# User-Facing Changes
The following test case now works as expected:

```nushell
> head -c 2 /dev/urandom | into binary
# Expected: pretty hex dump of binary
# Previous behavior: just raw binary in the terminal
```

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

Use pipeline data for http post|put|patch|delete commands. (#13254)
# Description
Provides the ability to use http commands as part of a pipeline.
Additionally, this pull requests extends the pipeline metadata to add a
content_type field. The content_type metadata field allows commands such
as `to json` to set the metadata in the pipeline allowing the http
commands to use it when making requests.

This pull request also introduces the ability to directly stream http
requests from streaming pipelines.

One other small change is that Content-Type will always be set if it is
passed in to the http commands, either indirectly or throw the content
type flag. Previously it was not preserved with requests that were not
of type json or form data.

# User-Facing Changes
* `http post`, `http put`, `http patch`, `http delete` can be used as
part of a pipeline
* `to text`, `to json`, `from json` all set the content_type metadata
field and the http commands will utilize them when making requests.

Skip decoration lines for detect columns --guess (#13274)
# Description
I introduced a regression in #13272 that resulted in `detect columns
--guess` to panic whenever it had to handle empty, whitespace-only, or
non-whitespace-only lines that go all the way to the last column (and as
such, cannot be considered to be lines that only have entries for the
first colum). I fix this by detecting these cases and skipping them,
since these are usually decoration lines. An example is the second line
output by `winget list`:

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

What we don't want to skip, however, is lines that contain no
whitespace, and fit into the detected first column, since these lines
represent cases where data is only available for the first column, and
are not just decoration lines. For example (made up example, there are
no such entries in `winget lits`'s output), in this output we would not
want to skip the `Docker Desktop` line :
```
Name                                                        Id                                           Version     Available Source

NOTE: `winget list | detect columns --guess` does not panic, but sadly
still does not work as expected. I believe this is not a nushell issue
anymore, but a `winget` one. When being piped, `winget` seems to add
extra whitespace and random `\r` symbols at the beginning of the text.
This messes with the column detection, of course.

# User-Facing Changes
`detect columns --guess` should not panic when receiving output from
`winget list` at all anymore.

A breaking change is the skipping of decoration lines, especially since
scripts probably were doing something like
`winget list | lines | reject 1 | str join "\n" | detect columns
--guess`. This will now cause them to reject a line with valid data.

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

This PR fixes #13269. The splitting code in `guess_width.rs` was
creating slices from char indices, instead of byte indices. This works
perfectly fine for 1-byte code points, but panics or returns wrong
results as soon as multibyte codepoints appear in the input. I
originally discovered this by piping `winget list` into `detect columns
--guess`, since winget sometimes uses the unicode ellipsis symbol (`…`)
which is 3 bytes long when encoded in utf-8.

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

fixed #11678

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

starting at index 0 if no header data is passed.

* Add example for `ls **/*` to demonstrate recursive listing using glob
pattern
* Add example for `ls ...(glob )`... to demonstrate recursive listing
using glob command
* Remove `-s` from an example where it had no use (since it was based on
the current directory and was not recursive)
* Update the description of `ls -a ~ `... to clarify that it lists the
full path of directories
* Update the description of `ls -as ~ `... (the difference being the
`-s`) to clarify that it lists only the filenames, not paths.

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

@hustcer reported that slashes were disappearing from external args
since #13089:

```
$> ossutil ls oss://abc/b/c
Error: invalid cloud url: "oss:/abc/b/c", please make sure the url starts with: "oss://"

$> ossutil ls 'oss://abc/b/c'
Error: oss: service returned error: StatusCode=403, ErrorCode=UserDisable, ErrorMessage="UserDisable", RequestId=66791EDEFE87B73537120838, Ec=0003-00000801, Bucket=abc, Object=
```

I narrowed this down to the ndots handling, since that does path parsing
and path reconstruction in every case. I decided to change that so that
it only activates if the string contains at least `...`, since that
would be the minimum trigger for ndots, and also to not activate it if
the string contains `://`, since it's probably undesirable for a URL.

Kind of a hack, but I'm not really sure how else we decide whether
someone wants ndots or not.

# User-Facing Changes
- bare strings not containing ndots are not modified
- bare strings containing `://` are not modified

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

* As discussed in the comments in #11954, this suppresses the index
column on `cal` output. It does that by running `table -i false` on the
results by default.
* Added new `--as-table/-t` flag to revert to the old behavior and
output the calendar as structured data
* Updated existing tests to use `--as-table`
* Added new tests against the string output
* Updated `length` test which also used `cal`
* Added new example for `--as-table`, with result

# User-Facing Changes

## Breaking change

The *default* `cal` output has changed from a `list` to a `string`. To
obtain structured data from `cal`, use the new `--as-table/-t` flag.

Fixed generate command signature (#13200)
# Description

Removes `list<any>` as an input type for the `generate` command. This
command does not accept pipeline input (and cannot, logically). This can
be seen by the use of `_input` in the command's `run()`.

Also, due to #13199, in order to pass `toolkit check pr`, one of the
examples was changed to remove the `result`. This is probably a better
demonstration of the ability of the command to infinitely generate a
list anyway, and an infinite list can't be represented in a `result`.

Should only be a change to the help. The input type was never valid and
couldn't have been used.

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

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

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

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

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

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

# User-Facing Changes

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

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

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

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

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

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

Table help rendering (#13182)
# Description

Mostly fixes #13149 with much of the credit to @fdncred.

This PR runs `table --expand` against `help` example results. This is
essentially the same fix that #13146 was for `std help`.

It also changes the shape of the result for the `table --expand`
example, as it was hardcoded wrong.

~Still needed is a fix for the `table --collapse` example.~ Note that
this is also still a bug in `std help` that I didn't noticed before.

# User-Facing Changes

* `table`
* `zip`
* `flatten`

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

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

cc @abusch

# User-Facing Changes

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

# Tests + Formatting

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

Improves commands that support range input (#13113)
# Description
Fixes: #13105
Fixes: #13077

This pr makes `str substring`, `bytes at` work better with negative
index.

And it also fixes the false range semantic on `detect columns -c` in
some cases.

# User-Facing Changes
For `str substring`, `bytes at`, it will no-longer return an error if
start index is larger than end index. It makes sense to return an empty
string of empty bytes directly.

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

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

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

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

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

Add derive macros for FromValue and IntoValue to ease the use of Values in Rust code (#13031)
# Description
After discussing with @sholderbach the cumbersome usage of
`nu_protocol::Value` in Rust, I created a derive macro to simplify it.
I’ve added a new crate called `nu-derive-value`, which includes two
macros, `IntoValue` and `FromValue`. These are re-exported in
`nu-protocol` and should be encouraged to be used via that re-export.

The macros ensure that all types can easily convert from and into
`Value`. For example, as a plugin author, you can define your plugin
configuration using a Rust struct and easily convert it using
`FromValue`. This makes plugin configuration less of a hassle.

I introduced the `IntoValue` trait for a standardized approach to
converting values into `Value` (and a fallible variant `TryIntoValue`).
This trait could potentially replace existing `into_value` methods.
Along with this, I've implemented `FromValue` for several standard types
and refined other implementations to use blanket implementations where
applicable.

I made these design choices with input from @devyn.

There are more improvements possible, but this is a solid start and the
PR is already quite substantial.

# User-Facing Changes

For `nu-protocol` users, these changes simplify the handling of
`Value`s. There are no changes for end-users of nushell itself.

# Tests + Formatting
Documenting the macros itself is not really possible, as they cannot
really reference any other types since they are the root of the
dependency graph. The standard library has the same problem
([std::Debug](https://doc.rust-lang.org/stable/std/fmt/derive.Debug.html)).
However I documented the `FromValue` and `IntoValue` traits completely.

For testing, I made of use `proc-macro2` in the derive macro code. This
would allow testing the generated source code. Instead I just tested
that the derived functionality is correct. This is done in
`nu_protocol::value::test_derive`, as a consumer of `nu-derive-value`
needs to do the testing of the macro usage. I think that these tests
should provide a stable baseline so that users can be sure that the impl
works.

# After Submitting
With these macros available, we can probably use them in some examples
for plugins to showcase the use of them.

Removes the `which-support` cargo feature and makes all of its

path type error and not found changes (#13007)
# Description
Instead of an empty string, this PR changes `path type` to return null
if the path does not exist. If some other IO error is encountered, then
that error is bubbled up instead of treating it as a "not found" case.

# User-Facing Changes
- `path type` will now return null instead of an empty string, which is
technically a breaking change. In most cases though, I think this
shouldn't affect the behavior of scripts too much.
- `path type` can now error instead of returning an empty string if some
other IO error besides a "not found" error occurs.

Since this PR introduces breaking changes, it should be merged after the
0.94.1 patch.

Part of https://github.com/nushell/nushell/issues/12963, step 2.

This PR refactors changes the use of `expression.span` to
`expression.span_id` via a new helper `Expression::span()`. A new
`GetSpan` is added to abstract getting the span from both `EngineState`
and `StateWorkingSet`.

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

`format pattern` loses the ability to use variables in the pattern,
e.g., `... | format pattern 'value of {$it.name} is {$it.value}'`. This
is because the command did a custom parse-eval cycle, creating spans
that are not merged into the main engine state. We could clone the
engine state, add Clone trait to StateDelta and merge the cloned delta
to the cloned state, but IMO there is not much value from having this
ability, since we have string interpolation nowadays: `... | $"value of
($in.name) is ($in.value)"`.

Use native toml datetime type in to toml (#13018)
# Description

Makes `to toml` use the `toml::value::Datetime` type, so that `to toml`

Allow stor insert and stor update to accept pipeline input (#12882)
- this PR should close #11433 

# Description
This PR implements pipeline input support for the stor insert and stor
update commands,
enabling users to directly pass data to these commands without relying
solely on flag parameters.

Previously, it was only possible to specify the record data using flag
parameters,
which could be less intuitive and become cumbersome:

```bash
stor insert --table-name nudb --data-record {bool1: true, int1: 5, float1: 1.1, str1: fdncred, datetime1: 2023-04-17}
stor update --table-name nudb --update-record {str1: nushell datetime1: 2020-04-17}
```

Now it is also possible to pass a record through pipeline input:

```bash
{bool1: true, int1: 5, float1: 1.1, str1: fdncred, datetime1: 2023-04-17} | stor insert --table-name nudb
{str1: nushell datetime1: 2020-04-17} | stor update --table-name nudb"
```

Changes made on code:

- Modified stor insert and stor update to accept a record from the
pipeline.
- Added logic to handle data from the pipeline record.
- Implemented an error case to prevent simultaneous data input from both
pipeline and flag.

# User-facing changes

Returns an error when both ways of inserting data are used.

The examples for both commands were updated and in each command, when
the -d or -u fags are being used at the same time as input is being
passed through the pipeline, it returns an error:


![image](https://github.com/nushell/nushell/assets/120738170/c5b15c1b-716a-4df4-95e8-3bca8f7ae224)

Also returns an error when both of them are missing:

this adds examples to the `help` for both:

to demonstrate that `def --env` is required when changing directories in

Since the existing examples for `def` were a bit more complex (and had

different examples in each. Either or both could be tweaked if desired.

First part of SpanID refactoring series. This PR adds a `SpanId` type
and a corresponding `span_id` field to `Expression`. Parser creating
expressions will now add them to an array in `StateWorkingSet`,
generates a corresponding ID and saves the ID to the Expression. The IDs
are not used anywhere yet.

For the rough overall plan, see
https://github.com/nushell/nushell/issues/12963.

# User-Facing Changes
Hopefully none. This is only a refactor of Nushell's internals that
shouldn't have visible side effects.

msgpackz: increase default compression level (#13035)
# Description
Increase default compression level for brotli on msgpackz to 3. This has
the best compression time generally. Level 0 and 1 give weird results
and sometimes cause extremely inflated outputs rather than being
compressed. So far this hasn't really been a problem for the plugin
registry file, but has been for other data.

The `$example` is the web-app example from https://json.org/example.html

Benchmarked with:

```nushell
seq 0 11 | each { |level|
  let compressed = ($example | to msgpackz --quality $level)
  let time = (timeit { $example | to msgpackz --quality $level })
  {
    level: $level
    time: $time
    length: ($compressed | bytes length)
    ratio: (($uncompressed_length | into float) / ($compressed | bytes length))
  }
}
```

Try to preserve the ordering of elements in from toml (#13045)
# Description

Enable the `preserve_order` feature of the `toml` crate to preserve the
ordering of elements when converting from/to toml.

Additionally, use `to_string_pretty()` instead of `to_string()` in `to
toml`. This displays arrays on multiple lines instead of one big single
line. I'm not sure if this one is a good idea or not... Happy to remove
this from this PR if it's not.

# User-Facing Changes
The order of elements will be different when using `from toml`. The
formatting of arrays will also be different when using `to toml`. For
example:

- before
```
❯ "foo=1\nbar=2\ndoo=3" | from toml
╭─────┬───╮
│ bar │ 2 │
│ doo │ 3 │
│ foo │ 1 │
╰─────┴───╯
❯ {a: [a b c d]} | to toml
a = ["a", "b", "c", "d"]
```
- after
```
❯ "foo=1\nbar=2\ndoo=3" | from toml
╭─────┬───╮
│ foo │ 1 │
│ bar │ 2 │
│ doo │ 3 │
╰─────┴───╯
❯ {a: [a b c d]} | to toml
a = [
    "a",
    "b",
    "c",
    "d",
]
```

Fix run_external::expand_glob() to return paths that are PWD-relative but reflect the original intent (#13028)
# Description

Fix #13021

This changes the `expand_glob()` function to use
`nu_engine::glob_from()` so that absolute paths are actually preserved,
rather than being made relative to the provided parent. This preserves
the intent of whoever wrote the original path/glob, and also makes it so
that tilde always produces absolute paths.

I also made `expand_glob()` handle Ctrl-C so that it can be interrupted.

Disallow more characters in arguments for internal cmd commands (#13009)
# Description
Makes `run-external` error if arguments to `cmd.exe` internal commands
contain newlines or a percent sign. This is because the percent sign can
expand environment variables, potentially? allowing command injection.
Newlines I think will truncate the rest of the arguments and should
probably be disallowed to be safe.

# After Submitting
- If the user calls `cmd.exe` directly, then this bypasses our
handling/checking for internal `cmd` commands. Instead, we use the
handling from the Rust std lib which, in this case, does not do special
handling and is potentially unsafe. Then again, it could be the user's
specific intention to run `cmd` with whatever trusted input. The problem
is that since we use the std lib handling, it assumes the exe uses the C
runtime escaping rules and will perform some unwanted escaping. E.g., it
will add backslashes to the quotes in `cmd echo /c '""'`.
- If `cmd` is called indirectly via a `.bat` or `.cmd` file, then we use
the Rust std lib which has separate handling for bat files that should
be safe, but will reject some inputs.
- ~~I'm not sure how we handle `PATHEXT`, that can also cause a file
without an extension to be run as a bat file. If so, I don't know where
the handling, if any, is done for that.~~ It looks like we use the
`which` crate to do the lookup using `PATHEXT`. Then, we pass the exe
path from that to the Rust std lib `Command`, which should be safe
(except for the first `cmd.exe` note).

So, in the future we need to unify and/or fix these different
implementations, including our own special handling for internal `cmd`
commands that this PR tries to fix.

Restore tilde expansion on external command names (#13001)
# Description

Fix a regression introduced by #12921, where tilde expansion was no
longer done on the external command name, breaking things like

```nushell
> ~/.cargo/bin/exa
```

This properly handles quoted strings, so they don't expand:

```nushell
> ^"~/.cargo/bin/exa"
Error: nu:🐚:external_command

  × External command failed
   ╭─[entry #1:1:2]
 1 │ ^"~/.cargo/bin/exa"
   ·  ─────────┬────────
   ·           ╰── Command `~/.cargo/bin/exa` not found
   ╰────
  help: `~/.cargo/bin/exa` is neither a Nushell built-in or a known external command

```

This required a change to the parser, so the command name is also parsed
in the same way the arguments are - i.e. the quotes on the outside
remain in the expression. Hopefully that doesn't break anything else. 🤞

Fixes #13000. Should include in patch release 0.94.1

cc @YizhePKU

# User-Facing Changes
- Tilde expansion now works again for external commands
- The `command` of `run-external` will now have its quotes removed like
the other arguments if it is a literal string
- The parser is changed to include quotes in the command expression of
`ExternalCall` if they were present

# Tests + Formatting
I would like to add a regression test for this, but it's complicated
because we need a well-known binary within the home directory, which
just isn't a thing. We could drop one there, but that's kind of a bad
behavior for a test to do. I also considered changing the home directory
for the test, but that's so platform-specific - potentially could get it
working on specific platforms though. Changing `HOME` env on Linux
definitely works as far as tilde expansion works.

Allow byte streams with unknown type to be compatiable with binary (#12959)
# Description
Currently, this pipeline doesn't work `open --raw file | take 100`,
since the type of the byte stream is `Unknown`, but `take` expects
`Binary` streams. This PR changes commands that expect
`ByteStreamType::Binary` to also work with `ByteStreamType::Unknown`.
This was done by adding two new methods to `ByteStreamType`:
`is_binary_coercible` and `is_string_coercible`. These return true if
the type is `Unknown` or matches the type in the method name.

Make from json --objects streaming (#12949)
# Description

Makes the `from json --objects` command produce a stream, and read
lazily from an input stream to produce its output.

Also added a helper, `PipelineData::get_type()`, to make it easier to
construct a wrong type error message when matching on `PipelineData`. I
expect checking `PipelineData` for either a string value or an `Unknown`
or `String` typed `ByteStream` will be very, very common. I would have
liked to have a helper that just returns a readable stream from either,
but that would either be a bespoke enum or a `Box<dyn BufRead>`, which
feels like it wouldn't be so great for performance. So instead, taking
the approach I did here is probably better - having a function that
accepts the `impl BufRead` and matching to use it.

# User-Facing Changes

- `from json --objects` no longer collects its input, and can be used
for large datasets or streams that produce values over time.

All passing.

Rewrite run_external.rs (#12921)
This PR is a complete rewrite of `run_external.rs`. The main goal of the
rewrite is improving readability, but it also fixes some bugs related to
argument handling and the PATH variable (fixes
https://github.com/nushell/nushell/issues/6011).

I'll discuss some technical details to make reviewing easier.

## Argument handling

Quoting arguments for external commands is hard. Like, *really* hard.
We've had more than a dozen issues and PRs dedicated to quoting
arguments (see Appendix) but the current implementation is still buggy.

Here's a demonstration of the buggy behavior:

```nu
let foo = "'bar'"
^touch $foo            # This creates a file named `bar`, but it should be `'bar'`
^touch ...[ "'bar'" ]  # Same
```

I'll describe how this PR deals with argument handling.

First, we'll introduce the concept of **bare strings**. Bare strings are
**string literals** that are either **unquoted** or **quoted by
backticks** [^1]. Strings within a list literal are NOT considered bare
strings, even if they are unquoted or quoted by backticks.

When a bare string is used as an argument to external process, we need
to perform tilde-expansion, glob-expansion, and inner-quotes-removal, in
that order. "Inner-quotes-removal" means transforming from
`--option="value"` into `--option=value`.

## `.bat` files and CMD built-ins

On Windows, `.bat` files and `.cmd` files are considered executable, but
they need `CMD.exe` as the interpreter. The Rust standard library
supports running `.bat` files directly and will spawn `CMD.exe` under
the hood (see
[documentation](https://doc.rust-lang.org/std/process/index.html#windows-argument-splitting)).
However, other extensions are not supported [^2].

Nushell also supports a selected number of CMD built-ins. The problem
with CMD is that it uses a different set of quoting rules. Correctly
quoting for CMD requires using
[Command::raw_arg()](https://doc.rust-lang.org/std/os/windows/process/trait.CommandExt.html#tymethod.raw_arg)
and manually quoting CMD special characters, on top of quoting from the
Nushell side. ~~I decided that this is too complex and chose to reject
special characters in CMD built-ins instead [^3]. Hopefully this will
not affact real-world use cases.~~ I've implemented escaping that works
reasonably well.

## `which-support` feature

The `which` crate is now a hard dependency of `nu-command`, making the
`which-support` feature essentially useless. The `which` crate is
already a hard dependency of `nu-cli`, and we should consider removing
the `which-support` feature entirely.

## Appendix

Here's a list of quoting-related issues and PRs in rough chronological
order.

[^1]: The idea that backtick-quoted strings act like bare strings was
introduced by Kubouch and briefly mentioned in [the language
reference](https://www.nushell.sh/lang-guide/chapters/strings_and_text.html#backtick-quotes).

[^2]: The documentation also said "running .bat scripts in this way may
be removed in the future and so should not be relied upon", which is
another reason to move away from this. But again, quoting for CMD is
hard.

[^3]: If anyone wants to try, the best resource I found on the topic is
[this](https://daviddeley.com/autohotkey/parameters/parameters.htm).

# User-Facing Changes

- `to csv` and `to tsv` now have `--columns <List(String)>`, to provide
the exact columns desired in the output. This is required for them to
have streaming output, because otherwise collecting the entire list is
necessary to determine the output columns. If we introduce
`TableStream`, this may become less necessary.

Add support for the ps command on FreeBSD, NetBSD, and OpenBSD (#12892)
# Description

I feel like it's a little sad that BSDs get to enjoy almost everything
other than the `ps` command, and there are some tests that rely on this
command, so I figured it would be fun to patch that and make it work.

The different BSDs have diverged from each other somewhat, but generally
have a similar enough API for reading process information via
`sysctl()`, with some slightly different args.

This supports FreeBSD with the `freebsd` module, and NetBSD and OpenBSD
with the `netbsd` module. OpenBSD is a fork of NetBSD and the interface
has some minor differences but many things are the same.

I had wanted to try to support DragonFlyBSD too, but their Rust version
in the latest release is only 1.72.0, which is too old for me to want to
try to compile rustc up to 1.77.2... but I will revisit this whenever
they do update it. Dragonfly is a fork of FreeBSD, so it's likely to be
more or less the same - I just don't want to enable it without testing
it.

Fixes #6862 (partially, we probably won't be adding `zfs list`)

# User-Facing Changes

Add string/binary type color to ByteStream (#12897)
# Description

This PR allows byte streams to optionally be colored as being
specifically binary or string data, which guarantees that they'll be
converted to `Binary` or `String` appropriately on `into_value()`,
making them compatible with `Type` guarantees. This makes them
significantly more broadly usable for command input and output.

There is still an `Unknown` type for byte streams coming from external
commands, which uses the same behavior as we previously did where it's a
string if it's UTF-8.

A small number of commands were updated to take advantage of this, just
to prove the point. I will be adding more after this merges.

# User-Facing Changes
- New types in `describe`: `string (stream)`, `binary (stream)`
- These commands now return a stream if their input was a stream:
  - `into binary`
  - `into string`
  - `bytes collect`
  - `str join`
  - `first` (binary)
  - `last` (binary)
  - `take` (binary)
  - `skip` (binary)
- Streams that are explicitly binary colored will print as a streaming
hexdump
  - example:
    ```nushell
    1.. | each { into binary } | bytes collect
    ```

# Tests + Formatting
I've added some tests to cover it at a basic level, and it doesn't break
anything existing, but I do think more would be nice. Some of those will
come when I modify more commands to stream.

# After Submitting
There are a few things I'm not quite satisfied with:

- **String trimming behavior.** We automatically trim newlines from
streams from external commands, but I don't think we should do this with
internal commands. If I call a command that happens to turn my string
into a stream, I don't want the newline to suddenly disappear. I changed
this to specifically do it only on `Child` and `File`, but I don't know
if this is quite right, and maybe we should bring back the old flag for
`trim_end_newline`
- **Known binary always resulting in a hexdump.** It would be nice to
have a `print --raw`, so that we can put binary data on stdout
explicitly if we want to. This PR doesn't change how external commands
work though - they still dump straight to stdout.

Otherwise, here's the normal checklist:

- [ ] release notes
- [ ] docs update for plugin protocol changes (added `type` field)

Use CommandType in more places (#12832)
# Description
Kind of a vague title, but this PR does two main things:
1. Rather than overriding functions like `Command::is_parser_keyword`,
this PR instead changes commands to override `Command::command_type`.
The `CommandType` returned by `Command::command_type` is then used to
automatically determine whether `Command::is_parser_keyword` and the
other `is_{type}` functions should return true. These changes allow us
to remove the `CommandType::Other` case and should also guarantee than
only one of the `is_{type}` functions on `Command` will return true.
2. Uses the new, reworked `Command::command_type` function in the `scope
commands` and `which` commands.


# User-Facing Changes
- Breaking change for `scope commands`: multiple columns (`is_builtin`,
`is_keyword`, `is_plugin`, etc.) have been merged into the `type`
column.
- Breaking change: the `which` command can now report `plugin` or
`keyword` instead of `built-in` in the `type` column. It may also now
report `external` instead of `custom` in the `type` column for known
`extern`s.

This changes the `collect` command so that it doesn't require a closure.

allow define it as a variable inside closure (#12888)
# Description
Fixes: #12690 

The issue is happened after
https://github.com/nushell/nushell/pull/12056 is merged. It will raise
error if user doesn't supply required parameter when run closure with
do.
And parser adds a `$it` parameter when parsing closure or block
expression.

I believe the previous behavior is because we allow such syntax on
previous version(0.44):
```nushell
let x = { print $it }
```
But it's no longer allowed after 0.60.  So I think they can be removed.

Add Span merging functions (#12511)
# Description
This PR adds a few functions to `Span` for merging spans together:
- `Span::append`: merges two spans that are known to be in order.
- `Span::concat`: returns a span that encompasses all the spans in a
slice. The spans must be in order.
- `Span::merge`: merges two spans (no order necessary).
- `Span::merge_many`: merges an iterator of spans into a single span (no
order necessary).

These are meant to replace the free-standing `nu_protocol::span`
function.

The spans in a `LiteCommand` (the `parts`) should always be in order
based on the lite parser and lexer. So, the parser code sees the most
usage of `Span::append` and `Span::concat` where the order is known. In
other code areas, `Span::merge` and `Span::merge_many` are used since
the order between spans is often not known.

Replace ExternalStream with new ByteStream type (#12774)
# Description
This PR introduces a `ByteStream` type which is a `Read`-able stream of
bytes. Internally, it has an enum over three different byte stream
sources:
```rust
pub enum ByteStreamSource {
    Read(Box<dyn Read + Send + 'static>),
    File(File),
    Child(ChildProcess),
}
```

This is in comparison to the current `RawStream` type, which is an
`Iterator<Item = Vec<u8>>` and has to allocate for each read chunk.

Currently, `PipelineData::ExternalStream` serves a weird dual role where
it is either external command output or a wrapper around `RawStream`.
`ByteStream` makes this distinction more clear (via `ByteStreamSource`)
and replaces `PipelineData::ExternalStream` in this PR:
```rust
pub enum PipelineData {
    Empty,
    Value(Value, Option<PipelineMetadata>),
    ListStream(ListStream, Option<PipelineMetadata>),
    ByteStream(ByteStream, Option<PipelineMetadata>),
}
```

The PR is relatively large, but a decent amount of it is just repetitive
changes.

This PR fixes #7017, fixes #10763, and fixes #12369.

This PR also improves performance when piping external commands. Nushell
should, in most cases, have competitive pipeline throughput compared to,
e.g., bash.
| Command | Before (MB/s) | After (MB/s) | Bash (MB/s) |
| -------------------------------------------------- | -------------:|
------------:| -----------:|
| `throughput \| rg 'x'` | 3059 | 3744 | 3739 |
| `throughput \| nu --testbin relay o> /dev/null` | 3508 | 8087 | 8136 |

# User-Facing Changes
- This is a breaking change for the plugin communication protocol,
because the `ExternalStreamInfo` was replaced with `ByteStreamInfo`.
Plugins now only have to deal with a single input stream, as opposed to
the previous three streams: stdout, stderr, and exit code.
- The output of `describe` has been changed for external/byte streams.
- Temporary breaking change: `bytes starts-with` no longer works with
byte streams. This is to keep the PR smaller, and `bytes ends-with`
already does not work on byte streams.
- If a process core dumped, then instead of having a `Value::Error` in
the `exit_code` column of the output returned from `complete`, it now is
a `Value::Int` with the negation of the signal number.

# After Submitting
- Update docs and book as necessary
- Release notes (e.g., plugin protocol changes)
- Adapt/convert commands to work with byte streams (high priority is
`str length`, `bytes starts-with`, and maybe `bytes ends-with`).
- Refactor the `tee` code, Devyn has already done some work on this.

There was a question in Discord today about how to remove empty rows

Implement PWD recovery (#12779)
This PR has two parts. The first part is the addition of the
`Stack::set_pwd()` API. It strips trailing slashes from paths for
convenience, but will reject otherwise bad paths, leaving PWD in a good
state. This should reduce the impact of faulty code incorrectly trying
to set PWD.
(https://github.com/nushell/nushell/pull/12760#issuecomment-2095393012)

The second part is implementing a PWD recovery mechanism. PWD can become
bad even when we did nothing wrong. For example, Unix allows you to
remove any directory when another process might still be using it, which
means PWD can just "disappear" under our nose. This PR makes it possible
to use `cd` to reset PWD into a good state. Here's a demonstration:

```sh
mkdir /tmp/foo
cd /tmp/foo

# delete "/tmp/foo" in a subshell, because Nushell is smart and refuse to delete PWD
nu -c 'cd /; rm -r /tmp/foo'

ls          # Error:   × $env.PWD points to a non-existent directory
            # help: Use `cd` to reset $env.PWD into a good state

cd /
pwd         # prints /

Shrink Value by boxing Range/Closure (#12784)
# Description
On 64-bit platforms the current size of `Value` is 56 bytes. The
limiting variants were `Closure` and `Range`. Boxing the two reduces the
size of Value to 48 bytes. This is the minimal size possible with our
current 16-byte `Span` and any 24-byte `Vec` container which we use in
several variants. (Note the extra full 8-bytes necessary for the
discriminant or other smaller values due to the 8-byte alignment of
`usize`)

This is leads to a size reduction of ~15% for `Value` and should overall
be beneficial as both `Range` and `Closure` are rarely used compared to
the primitive types or even our general container types.

Migrate to a new PWD API (part 2) (#12749)
Refer to #12603 for part 1.

We need to be careful when migrating to the new API, because the new API
has slightly different semantics (PWD can contain symlinks). This PR
handles the "obviously safe" part of the migrations. Namely, it handles
two specific use cases:

* Passing PWD into `canonicalize_with()`
* Passing PWD into `EngineState::merge_env()`

The first case is safe because symlinks are canonicalized away. The
second case is safe because `EngineState::merge_env()` only uses PWD to
call `std::env::set_current_dir()`, which shouldn't affact Nushell. The
commit message contains detailed stats on the updated files.

Because these migrations touch a lot of files, I want to keep these PRs
small to avoid merge conflicts.

Add sys subcommands (#12747)
# Description
Adds subcommands to `sys` corresponding to each column of the record
returned by `sys`. This is to alleviate the fact that `sys` now returns
a regular record, meaning that it must compute every column which might
take a noticeable amount of time. The subcommands, on the other hand,
only need to compute and return a subset of the data which should be
much faster. In fact, it should be as fast as before, since this is how
the lazy record worked (it would compute only each column as necessary).

I choose to add subcommands instead of having an optional cell-path
parameter on `sys`, since the cell-path parameter would:
- increase the code complexity (can access any value at any row or
nested column)
- prevents discovery with tab-completion
- hinders type checking and allows users to pass potentially invalid
columns

# User-Facing Changes
Deprecates `sys` in favor of the new `sys` subcommands.

Allow ls works inside dir with [] brackets (#12625)

Fixes: #12429

To fix the issue, we need to pass the `input pattern` itself to

`expanded path of input pattern` to `glob_from` function.
It causes globbing failed if expanded path includes `[]` brackets.

It's a pity that I have to duplicate `nu_engine::glob_from` function
into `ls`, because `ls` might convert from `NuGlob::NotExpand` to
`NuGlob::Expand`, in that case, `nu_engine::glob_from` won't work if
user want to ls for a directory which includes tilde:
```
mkdir "~abc"
ls "~abc"

So I need to duplicate `glob_from` function and pass original

the whole `into_pipeline_data(..)` route).

Bump base64 to 0.22.1 (#12757)
# Description
Bumps `base64` to 0.22.1 which fixes the alphabet used for binhex
encoding and decoding. This required updating some test expected output.

Related to PR #12469 where `base64` was also bumped and ran into the
failing tests.

# User-Facing Changes
Bug fix, but still changes binhex encoding and decoding output.

# Tests + Formatting
Updated test expected output.

Fix trailing slash in PWD set by cd (#12760)
# Description

Fixes #12758.

#12662 introduced a bug where calling `cd` with a path with a trailing
slash would cause `PWD` to be set to a path including a trailing slash,
which is not allowed. This adds a helper to `nu_path` to remove this,
and uses it in the `cd` command to clean it up before setting `PWD`.

# Tests + Formatting
I added some tests to make sure we don't regress on this in the future.

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

Report errors that occur on file operations in ls (#12033)
Currently errors just create empty entries inside of resulting
dataframes.

This changeset is meant to help debug #12004, though generally speaking
I do think it's worth having ways to make errors be visible in this kind
of pipeline be visible

Migrate to a new PWD API (#12603)
This is the first PR towards migrating to a new `$env.PWD` API that
returns potentially un-canonicalized paths. Refer to PR #12515 for
motivations.

## New API: `EngineState::cwd()`

The goal of the new API is to cover both parse-time and runtime use
case, and avoid unintentional misuse. It takes an `Option<Stack>` as
argument, which if supplied, will search for `$env.PWD` on the stack in
additional to the engine state. I think with this design, there's less
confusion over parse-time and runtime environments. If you have access
to a stack, just supply it; otherwise supply `None`.

## Deprecation of other PWD-related APIs

Other APIs are re-implemented using `EngineState::cwd()` and properly
documented. They're marked deprecated, but their behavior is unchanged.
Unused APIs are deleted, and code that accesses `$env.PWD` directly
without using an API is rewritten.

Deprecated APIs:

* `EngineState::current_work_dir()`
* `StateWorkingSet::get_cwd()`
* `env::current_dir()`
* `env::current_dir_str()`
* `env::current_dir_const()`
* `env::current_dir_str_const()`

Other changes:

* `EngineState::get_cwd()` (deleted)
* `StateWorkingSet::list_env()` (deleted)
* `repl::do_run_cmd()` (rewritten with `env::current_dir_str()`)

## `cd` and `pwd` now use logical paths by default

This pulls the changes from PR #12515. It's currently somewhat broken
because using non-canonicalized paths exposed a bug in our path
normalization logic (Issue #12602). Once that is fixed, this should
work.

## Future plans

This PR needs some tests. Which test helpers should I use, and where
should I put those tests?

I noticed that unquoted paths are expanded within `eval_filepath()` and
`eval_directory()` before they even reach the `cd` command. This means
every paths is expanded twice. Is this intended?

Once this PR lands, the plan is to review all usages of the deprecated
APIs and migrate them to `EngineState::cwd()`. In the meantime, these
usages are annotated with `#[allow(deprecated)]` to avoid breaking CI.

overhaul shell_integration to enable individual control over ansi escape sequences (#12629)
# Description

This PR overhauls the shell_integration system by allowing individual
control over which ansi escape sequences are used. As we continue to
broaden our support for more ansi escape sequences, we can't really have
an all-or-nothing strategy. Some ansi escapes cause problems in certain
operating systems or terminals. We should allow the user to choose which
escapes they want.

TODO:
* Gather feedback
* Should osc7, osc9_9 and osc633p be mutually exclusive?
* Is the naming convention for these settings too nerdy osc2, osc7, etc?

closes #11301

# User-Facing Changes
shell_integration is no longer a boolean value. This is what is
supported in the default_config.nu
```nushell
  shell_integration: {
    # osc2 abbreviates the path if in the home_dir, sets the tab/window title, shows the running command in the tab/window title
    osc2: true
    # osc7 is a way to communicate the path to the terminal, this is helpful for spawning new tabs in the same directory
    osc7: true
    # osc8 is also implemented as the deprecated setting ls.show_clickable_links, it shows clickable links in ls output if your terminal supports it
    osc8: true
    # osc9_9 is from ConEmu and is starting to get wider support. It's similar to osc7 in that it communicates the path to the terminal
    osc9_9: false
    # osc133 is several escapes invented by Final Term which include the supported ones below.
    # 133;A - Mark prompt start
    # 133;B - Mark prompt end
    # 133;C - Mark pre-execution
    # 133;D;exit - Mark execution finished with exit code
    # This is used to enable terminals to know where the prompt is, the command is, where the command finishes, and where the output of the command is
    osc133: true
    # osc633 is closely related to osc133 but only exists in visual studio code (vscode) and supports their shell integration features
    # 633;A - Mark prompt start
    # 633;B - Mark prompt end
    # 633;C - Mark pre-execution
    # 633;D;exit - Mark execution finished with exit code
    # 633;E - NOT IMPLEMENTED - Explicitly set the command line with an optional nonce
    # 633;P;Cwd=<path> - Mark the current working directory and communicate it to the terminal
    # and also helps with the run recent menu in vscode

add raw-string literal support (#9956)
# Description

This PR adds raw string support by using `r#` at the beginning of single
quoted strings and `#` at the end.

Notice that escapes do not process, even within single quotes,
parentheses don't mean anything, $variables don't mean anything. It's
just a string.
```nushell
❯ echo r#'one\ntwo (blah) ($var)'#
one\ntwo (blah) ($var)
```
Notice how they work without `echo` or `print` and how they work without
carriage returns.
```nushell
❯ r#'adsfa'#
adsfa
❯ r##"asdfa'@qpejq'##
asdfa'@qpejq
❯ r#'asdfasdfasf
∙ foqwejfqo@'23rfjqf'#
```
They also have a special configurable color in the repl. (use single
quotes though)

![image](https://github.com/nushell/nushell/assets/343840/8780e21d-de4c-45b3-9880-2425f5fe10ef)

They should work like rust raw literals and allow `r##`, `r###`,
`r####`, etc, to help with having one or many `#`'s in the middle of
your raw-string.

They should work with `let` as well.

```nushell
r#'some\nraw\nstring'# | str upcase
```

Make bytes build accept integer values as individual bytes (#12685)
# Description
This creates an option for building binary data from byte integers.
Previously I think you could only do this by formatting the integers to
hex and using `decode hex`.

One potentially confusing thing is that this is different from the `into
binary` behavior. But since this doesn't support any of the other `into
binary` behaviors, it might be okay.

# User-Facing Changes
- `bytes build` accepts single byte arguments as integers

Fix inconsistent print behavior (#12675)
# Description

I found a bunch of issues relating to the specialized reimplementation
of `print()` that's done in `nu-cli` and it just didn't seem necessary.
So I tried to unify the behavior reasonably. `PipelineData::print()`
already handles the call to `table` and it even has a `no_newline`
option.

One of the most major issues before was that we were using the value
iterator, and then converting to string, and then printing each with
newlines. This doesn't work well for an external stream, because its
iterator ends up creating `Value::binary()` with each buffer... so we
were doing lossy UTF-8 conversion on those and then printing them with
newlines, which was very weird:


![Screenshot_2024-04-26_02-02-29](https://github.com/nushell/nushell/assets/10729/131c2224-08ee-4582-8617-6ecbb3ce8da5)

You can see the random newline inserted in a break between buffers, but
this would be even worse if it were on a multibyte UTF-8 character. You
can produce this by writing a large amount of text to a text file, and
then doing `nu -c 'open file.txt'` - in my case I just wrote `^find .`;
it just has to be large enough to trigger a buffer break.

Using `print()` instead led to a new issue though, because it doesn't
abort on errors. This is so that certain commands can produce a stream
of errors and have those all printed. There are tests for e.g. `rm` that
depend on this behavior. I assume we want to keep that, so instead I
made my target `BufferedReader`, and had that fuse closed if an error
was encountered. I can't imagine we want to keep reading from a wrapped
I/O stream if an error occurs; more often than not the error isn't going
to magically resolve itself, it's not going to be a different error each
time, and it's just going to lead to an infinite stream of the same
error.

The test that broke without that was `open . | lines`, because `lines`
doesn't fuse closed on error. But I don't know if it's expected or not
for it to do that, so I didn't target that.

I think this PR makes things better but I'll keep looking for ways to
improve on how errors and streams interact, especially trying to
eliminate cases where infinite error loops can happen.

# User-Facing Changes
- **Breaking**: `BufferedReader` changes + no more public fields
- A raw I/O stream from e.g. `open` won't produce infinite errors
anymore, but I consider that to be a plus
- the implicit `print` on script output is the same as the normal one
now

# Tests + Formatting
Everything passes but I didn't add anything specific.

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`.

Shrink the size of Expr (#12610)
# Description
Continuing from #12568, this PR further reduces the size of `Expr` from
64 to 40 bytes. It also reduces `Expression` from 128 to 96 bytes and
`Type` from 32 to 24 bytes.

This was accomplished by:
- for `Expr` with multiple fields (e.g., `Expr::Thing(A, B, C)`),
merging the fields into new AST struct types and then boxing this struct
(e.g. `Expr::Thing(Box<ABC>)`).
- replacing `Vec<T>` with `Box<[T]>` in multiple places. `Expr`s and
`Expression`s should rarely be mutated, if at all, so this optimization
makes sense.

By reducing the size of these types, I didn't notice a large performance
improvement (at least compared to #12568). But this PR does reduce the
memory usage of nushell. My config is somewhat light so I only noticed a
difference of 1.4MiB (38.9MiB vs 37.5MiB).

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.

Add ErrSpan extension trait for Result (#12626)
# Description
This adds an extension trait to `Result` that wraps errors in `Spanned`,
saving the effort of calling `.map_err(|err| err.into_spanned(span))`
every time. This will hopefully make it even more likely that someone
will want to use a spanned `io::Error` and make it easier to remove the
impl for `From<io::Error> for ShellError` because that doesn't have span
information.

Refactor using ClosureEval types (#12541)
# Description
Adds two new types in `nu-engine` for evaluating closures: `ClosureEval`
and `ClosureEvalOnce`. This removed some duplicate code and centralizes
our logic for setting up, running, and cleaning up closures. For
example, in the future if we are able to reduce the cloning necessary to
run a closure, then we only have to change the code related to these
types.

`ClosureEval` and `ClosureEvalOnce` are designed with a builder API.
`ClosureEval` is used to run a closure multiple times whereas
`ClosureEvalOnce` is used for a one-shot closure.

# User-Facing Changes
Should be none, unless I messed up one of the command migrations.
Actually, this will fix any unreported environment bugs for commands
that didn't reset the env after running a closure.

Make the same file error more likely to appear (#12601)
# Description
When saving to a file we currently try to check if the data source in
the pipeline metadata is the same as the file we are saving to. If so,
we create an error, since reading and writing to a file at the same time
is currently not supported/handled gracefully. However, there are still
a few instances where this error is not properly triggered, and so this
PR attempts to reduce these cases. Inspired by #12599.

# Tests + Formatting
Added a few tests.

# After Submitting
Some commands still do not properly preserve metadata (e.g., `str trim`)
and so prevent us from detecting this error.

Remove the Value::Block case (#12582)
# Description
`Value` describes the types of first-class values that users and scripts
can create, manipulate, pass around, and store. However, `Block`s are
not first-class values in the language, so this PR removes it from
`Value`. This removes some unnecessary code, and this change should be
invisible to the user except for the change to `scope modules` described
below.

# User-Facing Changes
Breaking change: the output of `scope modules` was changed so that
`env_block` is now `has_env_block` which is a boolean value instead of a
`Block`.

# After Submitting
Update the language guide possibly.

add search_term "str extract" to parse command (#12600)

For a long time, I was searching for the `str extract` command to
extract regexes from strings. I often painfully used `str replace -r
'(.*)(pattern_to_find)(.*)' '$2'` for such purposes.
Only this morning did I realize that `parse` is what I needed for so
many times, which I had only used for parsing data in tables.

add "to nuon" enumeration of possible styles (#12591)
# Description
in order to change the style of the _serialized_ NUON data,
`nuon::to_nuon` takes three mutually exclusive arguments, `raw: bool`,
`tabs: Option<usize>` and `indent: Option<usize>` 🤔
this begs to use an enumeration with all possible alternatives, right?

this PR changes the signature of `nuon::to_nuon` to use `nuon::ToStyle`
which has three variants
- `Raw`: no newlines
- `Tabs(n: usize)`: newlines and `n` tabulations as indent
- `Spaces(n: usize)`: newlines and `n` spaces as indent

# User-Facing Changes
the signature of `nuon::to_nuon` changes from
```rust
to_nuon(
    input: &Value,
    raw: bool,
    tabs: Option<usize>,
    indent: Option<usize>,
    span: Option<Span>,
) -> Result<String, ShellError>
```
to
```rust
to_nuon(
    input: &Value,
    style: ToStyle,
    span: Option<Span>
) -> Result<String, ShellError>

create nuon crate from from nuon and to nuon (#12553)
# Description
playing with the NUON format in Rust code in some plugins, we agreed
with the team it was a great time to create a standalone NUON format to
allow Rust devs to use this Nushell file format.

> **Note**
> this PR almost copy-pastes the code from
`nu_commands/src/formats/from/nuon.rs` and
`nu_commands/src/formats/to/nuon.rs` to `nuon/src/from.rs` and
`nuon/src/to.rs`, with minor tweaks to make then standalone functions,
e.g. remove the rest of the command implementations

### TODO
- [x] add tests
- [x] add documentation

# User-Facing Changes
devs will have access to a new crate, `nuon`, and two functions,
`from_nuon` and `to_nuon`
```rust
from_nuon(
    input: &str,
    span: Option<Span>,
) -> Result<Value, ShellError>
```
```rust
to_nuon(

    indent: Option<usize>,
    span: Option<Span>,
) -> Result<String, ShellError>

# Tests + Formatting

`crates/nu-command/tests/format_conversions/nuon.rs` and converted them
to use `from_nuon` and `to_nuon` instead of Nushell commands

optional middle value to check that all is fine

Fix circular source causing Nushell to crash (#12262)
# Description

EngineState now tracks the script currently running, instead of the
parent directory of the script. This also provides an easy way to expose
the current running script to the user (Issue #12195).

Similarly, StateWorkingSet now tracks scripts instead of directories.
`parsed_module_files` and `currently_parsed_pwd` are merged into one
variable, `scripts`, which acts like a stack for tracking the current
running script (which is on the top of the stack).

Circular import check is added for `source` operations, in addition to
module import. A simple testcase is added for circular source.

add ability to set metadata (#12564)
# Description

This PR adds the ability to set metadata. This is especially useful for
activating LS_COLORS when using table literals.


![image](https://github.com/nushell/nushell/assets/343840/feef6433-f592-43ea-890a-38cb2df35686)

You can also set the filepath metadata, although I'm not really user how
useful this is. We may end up removing this option entirely.
```nushell
❯ "crates" | metadata set --datasource-filepath $'(pwd)/crates' | metadata
╭────────┬───────────────────────────────────╮
│ source │ /Users/fdncred/src/nushell/crates │
╰────────┴───────────────────────────────────╯
```

No file paths are checked. You could also do this.
```nushell
❯ "crates" | metadata set --datasource-filepath $'a/b/c/d/crates' | metadata
╭────────┬────────────────╮
│ source │ a/b/c/d/crates │
╰────────┴────────────────╯
```

The command name and parameter names are still WIP. We could change
them.

There are currently 3 kinds of metadata in nushell.
```rust
pub enum DataSource {
    Ls,
    HtmlThemes,
    FilePath(PathBuf),
}
```

I've skipped adding `HtmlThemes` because it seems to be specific to our
`to html` command only.

Add ListItem type for Expr::List (#12529)
# Description
This PR adds a `ListItem` enum to our set of AST types. It encodes the
two possible expressions inside of list expression: a singular item or a
spread. This is similar to the existing `RecordItem` enum. Adding
`ListItem` allows us to remove the existing `Expr::Spread` case which
was previously used for list spreads. As a consequence, this guarantees
(via the type system) that spreads can only ever occur inside lists,
records, or as command args.

This PR also does a little bit of cleanup in relevant parser code.

Replace subtraction of Instants and Durations with saturating subtractions (#12549)
# Description
Duration can not be negative, and an underflow causes a panic.

This should fix #12539 as from what I can tell that bug was caused in
`nu-explore:📟:events` from subtracting durations, but I figured
this might be more widespread, and saturating to zero generally makes
sense.

I also added the relevant clippy lint to try to prevent this from
happening in the future. I can't think of a reason we would ever want to
subtract durations without checking first.

Make group-by return errors in closure (#12508)
# Description
When a closure if provided to `group-by`, errors that occur in the
closure are currently ignored. That is, `group-by` will fall back and
use the `"error"` key if an error occurs. For example, the code snippet
below will group all `ls` entries under the `"error"` column.
```nushell
ls | group-by { get nope } 
```

This PR changes `group-by` to instead bubble up any errors triggered
inside the closure. In addition, this PR also does some refactoring and
cleanup inside `group-by`.

# User-Facing Changes
Errors are now returned from the closure provided to `group-by` instead
of falling back to the `"error"` group/key.

Copy-on-write for record values (#12305)
# Description
This adds a `SharedCow` type as a transparent copy-on-write pointer that
clones to unique on mutate.

As an initial test, the `Record` within `Value::Record` is shared.

There are some pretty big wins for performance. I'll post benchmark
results in a comment. The biggest winner is nested access, as that would
have cloned the records for each cell path follow before and it doesn't
have to anymore.

The reusability of the `SharedCow` type is nice and I think it could be
used to clean up the previous work I did with `Arc` in `EngineState`.
It's meant to be a mostly transparent clone-on-write that just clones on
`.to_mut()` or `.into_owned()` if there are actually multiple
references, but avoids cloning if the reference is unique.

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.

Rename IoStream to OutDest (#12433)
# Description
I spent a while trying to come up with a good name for what is currently

1. Implies that it is a stream, when it all it really does is specify
the output destination for a stream/pipeline.
2. Implies that it handles input and output, when it really only handles
output.

So, this PR renames `IoStream` to `OutDest` instead, which should be
more clear.

Fix nushell#10591: encode returns error with utf-16le and utf-16be encodings (nushell#10591) (#12411)

This closes (nushell#10591)

The Command encode's help text says that utf-16le and utf-16be encodings

Fix stop suggesting --trash when already enabled (issue #12361) (#12362)
fixes #12361

Looking at the condition, `TRASH_SUPPORTED && (trash || (rm_always_trash
&& !permanent))`, this code path seems only to run when `--trash` is
enabled and `--permanent` is disabled.

This suggests that the `--trash` suggestion is a mistake and should have

Fix #12391: mkdir uses process startup directory instead of current script directory (#12394)
# Description

This fixes #12391.

nushell/nushell@87c5f6e455 accidentally introduced a bug where the path
was not being properly
expanded according to the cwd. This makes both 'touch' and 'mkdir' use
globs just like the rest of
the commands to preserve tilde behavior while still expanding the paths
properly.

This doesn't actually expand the globs. Should it?

# User-Facing Changes

- Restore behavior of `mkdir`, `touch`
- Help text now says they can take globs, but they won't actually expand
them, maybe this should be changed

# Tests + Formatting

Regression tests added.


# After Submitting

This is severe enough and should be included in the point release.

Make drop notification timing for plugin custom values more consistent (#12341)
# Description
This keeps plugin custom values that have requested drop notification
around during the lifetime of a plugin call / stream by sending them to
a channel that gets persisted during the lifetime of the call.

Before this change, it was very likely that the drop notification would
be sent before the plugin ever had a chance to handle the value it
received.

Tests have been added to make sure this works - see the `custom_values`
plugin.

# User-Facing Changes
This is basically just a bugfix, just a slightly big one.

However, I did add an `as_mut_any()` function for custom values, to
avoid having to clone them. This is a breaking change.

into sqlite: Fix insertion of null values (#12328)
# Description

In #10232, the allowed input types were changed to be stricter, only
allowing records with types that can easily map onto sqlite equivalents.
Unfortunately, null was left out of the accepted input types, which
makes inserting rows with null values impossible.

This change fixes that by accepting null values as input.

One caveat of this is that when the command is creating a new table, it
uses the first row to infer an appropriate sqlite schema. If the first
row contains a null value, then it is impossible to tell which type this
column is supposed to have.

Throwing a hard error seems undesirable from a UX perspective, but
guessing can lead to a potentially useless database if we guess wrong.

So as a compromise, for null columns, we will assume the sqlite type is
TEXT and print a warning so the user knows. For the time being, if users
can't avoid a first row with null values, but also wants the right
schema, they are advised to create their table before running `into
sqlite`.

A future PR can add the ability to explicitly specify a schema.

Fixes #12225

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.

handle `ShellError::Return` as a passing of a `Value`

Change default algorithm in detect columns (#12277)
# Description
@fdncred found another histogram based algorithm to detect columns, and
rewrite it in rust: https://github.com/fdncred/guess-width

I have tested it manually, and it works good with `df`, `docker ps`,
`^ps`. This pr is going to use the algorithm in `detect columns`

Fix: #4183

The pitfall of new algorithm:
1. it may not works well if there isn't too much rows of input
2. it may not works well if the length of value is less than the header
to value, e.g:
```
c1 c2 c3 c4 c5
a b c d e
g h i j k
g a a q d
a v c q q | detect columns
```
In this case, users might need to use ~~`--old`~~ `--legacy` to make it
works well.

# User-Facing Changes
User might need to add ~~`--old`~~ `--legacy` to scripts if they find
`detect columns` in their scripts broken.

# Tests + Formatting
Done

Initial implementation for uutils uname (#11684)
Hi,
This PR aims at implementing the first iteration for `uname` using
`uutils`. Couple of things:
* Currently my [PR](https://github.com/uutils/coreutils/pull/5921) to
make the required changes is pending in `uutils` repo.
* I guess the number of flags has to be investigated. Still the tests
cover all of them.

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.

Initial --params implementation (#12249)
# Description
This PR adds a `--params` param to `query db`. This closes #11643.

You can't combine both named and positional parameters, I think this
might be a limitation with rusqlite itself. I tried using named
parameters with indices like `{ ':named': 123, '1': "positional" }` but
that always failed with a rusqlite error. On the flip side, the other
way around works: for something like `VALUES (:named, ?)`, you can treat
both as positional: `-p [hello 123]`.

This PR introduces some very gnarly code repetition in
`prepared_statement_to_nu_list`. I tried, I swear; the compiler wasn't
having any of it, it kept telling me to box my closures and then it said
that the reference lifetimes were incompatible in the match arms. I gave
up and put the mapping code in the match itself, but I'm still not
happy.

Another thing I'm unhappy about: I don't like how you have to put the
`:colon` in named parameters. I think nushell should insert it if it's
[missing](https://www.sqlite.org/lang_expr.html#parameters). But this is
the way [rusqlite
works](https://docs.rs/rusqlite/latest/rusqlite/trait.Params.html#example-named),
so for now, I'll let it be consistent. Just know that it's not really a
blocker, and it isn't a compatibility change to later make `{ colon: 123
}` work, without the quotes and `:`. This would require allocating and
turning our pretty little `&str` into a `String`, though

# User-Facing Changes
Less incentive to leave yourself open to SQL injection with statements
like `query db $"INSERT INTO x VALUES \($unsafe_user_input)"`.
Additionally, the `$""` syntax being annoying with parentheses plays in
our favor, making users even more likely to use ? with `--params`.

Bump base64 from 0.21.7 to 0.22.0 (#12188)
Bumps [base64](https://github.com/marshallpierce/rust-base64) from

<p><em>Sourced from <a

changelog</a>.</em></p>
<blockquote>
<h1>0.22.0</h1>
<ul>
<li><code>DecodeSliceError::OutputSliceTooSmall</code> is now
conservative rather than precise. That is, the error will only occur if
the decoded output <em>cannot</em> fit, meaning that
<code>Engine::decode_slice</code> can now be used with exactly-sized
output slices. As part of this, <code>Engine::internal_decode</code> now
returns <code>DecodeSliceError</code> instead of
<code>DecodeError</code>, but that is not expected to affect any
external callers.</li>
<li><code>DecodeError::InvalidLength</code> now refers specifically to
the <em>number of valid symbols</em> being invalid (i.e. <code>len % 4
== 1</code>), rather than just the number of input bytes. This avoids
confusing scenarios when based on interpretation you could make a case
for either <code>InvalidLength</code> or <code>InvalidByte</code> being
appropriate.</li>
<li>Decoding is somewhat faster (5-10%)</li>

When the `command_not_found` hook is entered, we set an environment
variable for context. If an unknown command is encountered and the
`command_not_found` context environment variable is already present, it
implies a command in the hook closure is also not found. We stop the
recursion right there.

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.

# User-Facing Changes

Fix usage of --tabs flag while converting to json (#12115) (#12251)
closes #12115 

# Description
This fix addresses a bug where the --tabs flag couldn't be utilized due
to improper handling of the tab quantity provided by the user.
Previously, the code mistakenly attempted to convert the tab quantity to
a boolean value, leading to a conversion error. The resolution involves
adjusting the condition clauses to properly validate the presence of the
flag's value. Now, the code checks whether the get_flag() function
returns a value or None associated with the --tabs flag. This adjustment
enables the --tabs flag to function correctly, triggering the
appropriate condition and allowing the conversion to proceed as
expected. Similarly, the fix applies to the --indent flag. Additionally,
a default case was added, and the conversion now works properly without
flags. Two tests were added to validate the corrected behavior of these
flags.

# User-Facing Changes
Now the conversion should work properly instead of displaying an error.

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?

values

With this change, `mkdir` mirrors coreutils works. Closes #12161

I referred to the implementation of `mkdir` in uutils/coreutils. I add
`uucore` required for implementation to dependencies. Since `uucore` is
already included in dependencies of `uu_mkdir`, I don't think there will
be any additional dependencies.

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).

The language guide and other documentation will need to be updated.

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 🎉 

# Tests + Formatting
Tests were added for all of the new custom values functionality.

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

# After Submitting
- [ ] Document protocol reference `CustomValueOp` variants:
  - [ ] `FollowPathInt`
  - [ ] `FollowPathString`
  - [ ] `PartialCmp`
  - [ ] `Operation`
  - [ ] `Dropped`
- [ ] Document `notify_on_drop` optional field in `PluginCustomValue`

Remove feat extra and include in default (#12140)
# Description
The intended effect of the `extra` feature has been undermined by
introducing the full builds on our release pages and having more
activity on some of the extra commands.

To simplify the feature matrix let's get rid of it and focus our effort
on truly either refining a command to well-specified behavior or
discarding it entirely from the `nu` binary and moving it into plugins.

## Details
- Remove `--features extra` from CI
- Don't explicitly name `extra` in full build wf
- Remove feature extra from build-help scripts
- Update README in `nu-cmd-extra`
- Remove feature `extra`
- Fix previously dead `format pattern` tests
- Relax signature of `to html`
- Fix/ignore `html::test_no_color_flag`
- Remove dead features from `version`
- Refine `to html` type signature

# User-Facing Changes
The commands that were previously only available when building with
`--features extra` will now be available to everyone. This increases the
number of dependencies slightly but has a limited impact on the overall
binary size.

# Tests + Formatting
Some tests that were left in `nu-command` during cratification were dead
because the feature was not passed to `nu-command` and only to
`nu-cmd-lang` for feature-flag mention in `version`.
Those tests have now been either fixed or ignored in one case.

# After Submitting
There may be places in the documentation where we point to `--features
extra` that will now be moot (apart from the generated command help)

This PR refactors `nu-check` and makes it possible to check module
directories. Also removes the requirement for files to end with .nu: It
was too limiting for module directories and there are executable scripts
[around](https://github.com/nushell/nu_scripts/tree/main/make_release/release-note)
that do not end with .nu, it's a common practice for scripts to omit it.

Other changes are:
* Removed the `--all` flag and heuristic parse because these are
irrelevant now when module syntax is a subset of script syntax (i.e.,
every module can be parsed as script).
* Reduced code duplication and in general tidied up the code
* Replaced unspanned errors with spanned ones.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

Fix up ctrl+C handling in into_sqlite (#12130)
I noticed that ctrl+C handling wasn't fully wired up in `into sqlite`,
for some data types we were ignoring ctrl+C presses.

I fixed that up and also made sure we roll back the current transaction
when cancelling (without that, I think we leak memory and database
locks).

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

Change the ignore command to use drain() instead of collecting a value (#12120)
# Description

Change the `ignore` command to use `drain()` instead of collecting a
value.

This saves memory usage when piping a lot of output to `ignore`. There's
no reason to keep the output in memory if it's going to be discarded
anyway.

# User-Facing Changes
Probably none

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.

fix du --exclude globbing bug (#12093)
# Description

This PR fixes a globbing bug in the `du` command. The problem was that
`--exclude` needed to be a `NuGlob` instead of a `String`. A variety of
ways were tried to fix this, including spread operators and `into glob`
but none of them worked. Here's the [Discord

Adjust examples in date commands (#12055)
Hello! This is my first PR to nushell, as I was looking at things for
#5066. The usage text for the date commands seemed fine to me, so this
is just a bit of a tidy up of the examples, mostly the description text.

# Description

- Remove two incorrect examples for `date to-record` and `date to-table`
where nothing was piped in (which causes an error in actual use).

- Fix misleading descriptions in `date to-timezone` which erroneously
referred to Hawaii's time zone.

- Standardise on "time zone" in written descriptions.

- Generally tidy up example descriptions and improve consistency.

# User-Facing Changes

Only in related help text showing examples.

Improve sleep resolution (#12049)
# Description
This improves the resolution of the sleep commands by simply not
clamping to the default 100ms ctrl+c signal checking loop if the
passed-in duration is shorter.

# User-Facing Changes
You can use smaller values in sleep.

```
# Before
timeit { 0..100 | each { |row| print $row; sleep 10ms; } } # +10sec

It still depends on the internal behavior of thread::sleep and the OS
timers. In windows it doesn't seem to go much lower than 15 or 10ms, or
0 if you asked for that.

# After Submitting
Sleep didn't have anything documenting its minimum value, so this should
be more in line with its standard procedure. It will still never sleep
for less time than allocated.

Did you know `sleep` can take multiple durations, and it'll add them up?

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.

# User-Facing Changes
Fewer panics!

This command mixes input from multiple sources and sends items to the
final stream as soon as they're available. It can be called as part of a
pipeline with input, or it can take multiple closures and mix them that
way.

See `crates/nu-command/tests/commands/interleave.rs` for a practical
example. I imagine this will be most often used to run multiple commands
in parallel and print their outputs line-by-line. A stdlib command could
potentially use `interleave` to make this particular use case easier.

It's quite common to wish that nushell had a command for running things
in the background, and instead of providing job control, this provides
an alternative to some use cases for that by just allowing multiple
commands to run simultaneously and direct their output to the same
place.

This enables certain things that are not possible with `par-each` - for
example, you may wish to run `make` across several projects in parallel:

```nushell
(ls projects).name | par-each { |project| cd $project; make }
```

This works well enough, but the output will only be available after each
`make` command finishes. `interleave` allows you to get each line:

```nushell
interleave ...(
  (ls projects).name | each { |project|
    {
      cd $project
      make | lines | each { |line| {project: $project, out: $line} }
    }
  }
)
```

The result of this is a stream that you could process further - for
example, by saving to a text file.

Note that the closures themselves are not run in parallel. The initial
execution happens serially, and then the streams are consumed in
parallel.

Fix for #11757.
The main issue in #11757 is I tried to copy the timestamp from one
directory to another only to realize that did not work whereas the
coreutils `^touch` had no problems. I thought `--reference` just did not
work, but apparently the whole `touch` command could not work on
directories because
`OpenOptions::new().write(true).create(true).open(&item)` tries to
create `touch`'s target in advance and then modify its timestamps. But
if the target is a directory that already exists then this would fail
even though the crate used for working with timestamps, `filetime`,
already works on directories.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

I don't believe this should change any existing valid behaviors. It just
changes a non-working behavior.

add is-not-empty command as a QOL improvement (#11991)
# Description

This PR adds `is-not-empty` as a counterpart to `is-empty`. It's the
same code but negates the results. This command has been asked for many
times. So, I thought it would be nice for our community to add it just
as a quality-of-life improvement. This allows people to stop writing
their `def is-not-empty [] { not ($in | is-empty) }` custom commands.

I'm sure there will be some who disagree with adding this, I just think
it's like we have `in` and `not-in` and helps fill out the language and
makes it a little easier to use.

This is inspired by the Unix tee command, but significantly more
powerful. Rather than just writing to a file, you can do any kind of
stream operation that Nushell supports within the closure.

The equivalent of Unix `tee -a file.txt` would be, for example, `command
| tee { save -a file.txt }` - but of course this is Nushell, and you can
do the same with structured data to JSON objects, or even just run any
other command on the system with it.

A `--stderr` flag is provided for operating on the stderr stream from
external programs. This may produce unexpected results if the stderr
stream is not then also printed by something else - nushell currently
doesn't. See #11929 for the fix for that.

If someone was using the system `tee` command, they might be surprised

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.
```
