This PR fixes the problem pointed out in
https://github.com/nushell/nushell/issues/13204, where the Fish-like
completions aren't sorted properly (this PR doesn't close that issue
because the author there wants more than just fixed sort order).
The cause is all of the file/directory completions being fetched first
and then sorted all together while being treated as strings. Instead,
this PR sorts completions within each individual directory, avoiding
treating `/` as part of the path.
To do this, I removed the `sort` method from the completer trait (as
well as `get_sort_by`) and made all completers sort within the `fetch`
method itself. A generic `sort_completions` helper has been added to
sort lists of completions, and a more specific `sort_suggestions` helper
has been added to sort `Vec<Suggestion>`s.
As for the actual change that fixes the sort order for file/directory
completions, the `complete_rec` helper now sorts the children of each
directory before visiting their children. The file and directory
completers don't bother sorting at the end (except to move hidden files
down).
To reviewers: don't let the 29 changed files scare you, most of those
are just the test fixtures :)

Notice how `partial/hello.txt` is the last suggestion, even though it
should come before `partial-a`. This is because the ASCII code for `/`
is greater than that of `-`, so `partial-` is put before `partial/`.
This is this PR's behavior with prefix matching (`partial/hello.txt` is

even fixed anything
- Modified fixture to test sort order of .nu completions (a previous
version of my changes didn't sort all the completions at the end but
there were no tests catching that)
- Added a test for making sure subcommand completions are sorted by
Levenshtein distance (a previous version of my changes sorted in

In this pull request, I converted the `perf` function within `nu_utils`
to a macro. This change facilitates easier usage within plugins by
allowing the use of `env_logger` and setting `RUST_LOG=nu_plugin_polars`
(or another plugin). Without this conversion, the `RUST_LOG` variable
would need to be set to `RUST_LOG=nu_utils::utils`, which is less
intuitive and impossible to narrow the perf results to one plugin.

# Description
This allows plugins to report their version (and potentially other
metadata in the future). The version is shown in `plugin list` and in
`version`.
The metadata is stored in the registry file, and reflects whatever was
retrieved on `plugin add`, not necessarily the running binary. This can
help you to diagnose if there's some kind of mismatch with what you
expect. We could potentially use this functionality to show a warning or
error if a plugin being run does not have the same version as what was
in the cache file, suggesting `plugin add` be run again, but I haven't
done that at this point.
It is optional, and it requires the plugin author to make some code
changes if they want to provide it, since I can't automatically
determine the version of the calling crate or anything tricky like that
to do it.
Example:
```
> plugin list | select name version is_running pid
╭───┬────────────────┬─────────┬────────────┬─────╮
│ # │ name │ version │ is_running │ pid │
├───┼────────────────┼─────────┼────────────┼─────┤
│ 0 │ example │ 0.93.1 │ false │ │

# Description
This PR adds a directory to the `$nu` constant that shows where the
system level autoload directory is located at. This folder is modifiable
at compile time with environment variables.
```rust
// Create a system level directory for nushell scripts, modules, completions, etc
// that can be changed by setting the NU_VENDOR_AUTOLOAD_DIR env var on any platform
// before nushell is compiled OR if NU_VENDOR_AUTOLOAD_DIR is not set for non-windows
// systems, the PREFIX env var can be set before compile and used as PREFIX/nushell/vendor/autoload
// pseudo code
// if env var NU_VENDOR_AUTOLOAD_DIR is set, in any platform, use it
// if not, if windows, use ALLUSERPROFILE\nushell\vendor\autoload
// if not, if non-windows, if env var PREFIX is set, use PREFIX/share/nushell/vendor/autoload
// if not, use the default /usr/share/nushell/vendor/autoload
```
### Windows default
```nushell
❯ $nu.vendor-autoload-dir
C:\ProgramData\nushell\vendor\autoload
```
### Non-Windows default
```nushell
❯ $nu.vendor-autoload-dir
/usr/local/share/nushell/vendor/autoload
```
### Non-Windows with PREFIX set
```nushell
❯ PREFIX=/usr/bob cargo r
❯ $nu.vendor-autoload-dir
/usr/bob/share/nushell/vendor/autoload
```
### Non-Windows with NU_VENDOR_AUTOLOAD_DIR set
```nushell
❯ NU_VENDOR_AUTOLOAD_DIR=/some/other/path/nushell/stuff cargo r
❯ $nu.vendor-autoload-dir
/some/other/path/nushell/stuff
```
> [!IMPORTANT]
To be clear, this PR does not do the auto-loading, it just sets up the
folder to support that functionality that can be added in a later PR.
The PR also does not create the folder defined. It's just setting the
$nu constant.

# 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.
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`
# After Submitting
- [ ] release notes: make sure to mention the new syntaxes that are
supported
# 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 😉

# 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.
# Description
This PR is an attempt to add a standard location for people to put
completions in. I saw this topic come up again recently and IIRC we
decided to create a standard location. I used the dirs-next crate to
dictate where these locations are. I know some people won't like that
but at least this gets the ball rolling in a direction that has a
standard directory.
This is what the default NU_LIB_DIRS looks like now in the
default_env.nu. It should also be like this when starting nushell with
`nu -n`
```nushell
$env.NU_LIB_DIRS = [
($nu.default-config-dir | path join 'scripts') # add <nushell-config-dir>/scripts
($nu.data-dir | path join 'completions') # default home for nushell completions
]
```
I also added these default folders to the `$nu` variable so now there is
`$nu.data-path` and `$nu.cache-path`.
## Data Dir Default

## Cache Dir Default

How my NU_LIB_DIRS is set in the images above
```nushell
$env.NU_LIB_DIRS = [
($nu.default-config-dir | path join 'scripts') # add <nushell-config-dir>/scripts
'/Users/fdncred/src/nu_scripts'
($nu.config-path | path dirname)
($nu.data-dir | path join 'completions') # default home for nushell completions
]
```
Let the debate begin.

This one trace message creates thousands of lines of trace messages that
is probably
better suited to using on an *as needed* basis rather than everyone
having to wade

For now, I just commented it out but eventually this line of code should
be removed
and used simply for the time when someone needs to see it...
# Description
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

As discussed in https://github.com/nushell/nushell/pull/12749, we no
longer need to call `std::env::set_current_dir()` to sync `$env.PWD`
with the actual working directory. This PR removes the call from
`EngineState::merge_env()`.

- **Remove unused `serde_json` dep on `nu-protocol`**
- Unnecessary after moving the plugin file to msgpack (still a

# 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)

# Description
Changes `get_full_help` to take a `&dyn Command` instead of multiple
arguments (`&Signature`, `&Examples` `is_parser_keyword`). All of these
arguments can be gathered from a `Command`, so there is no need to pass
the pieces to `get_full_help`.
This PR also fixes an issue where the search terms are not shown if
`--help` is used on a command.
# 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.
# 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.

# Description
In order for `Stack::unwrap_unique` to work as intended, we currently
manually track all references to the parent stack and ensure that they
are cleared before calling `Stack::unwrap_unique` in the REPL. We also
only call `Stack::unwrap_unique` after all code from the current REPL
entry has finished executing. Since `Value`s cannot store `Stack`
references, then this should have worked in theory. However, we forgot
to account for threads. `run-external` (and maybe the plugin writers)
can spawn threads that clone the `Stack`, holding on to references of
the parent stack. These threads are not waited/joined upon, and so may
finish after the eval has already returned. This PR removes the
`Stack::unwrap_unique` function and associated debug assert that was
[causing
panics](https://gist.github.com/cablehead/f3d2608a1629e607c2d75290829354f7)
like @cablehead found.
# After Submitting
Make values cheaper to clone as a more robust solution to the
performance issues with cloning the stack.

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 /
```
Also, auto-cd should be working again.
# Description
Refactors the code in `nu-cli`, `main.rs`, `run.rs`, and few others.
Namely, I added `EngineState::generate_nu_constant` function to
eliminate some duplicate code. Otherwise, I changed a bunch of areas to
return errors instead of calling `std::process::exit`.
# User-Facing Changes
Should be none.
# Description
Fixes#12813 where a panic occurs when syntax highlighting `not`. Also
fixes#12814 where syntax highlighting for `not` no longer works.
# User-Facing Changes
Bug fix.
# Description
Adds an additional `&Stack` parameter to `Completer::fetch` so that the
completers don't have to store a `Stack` themselves. I also removed
unnecessary `EngineState`s from the completers, since the same
`EngineState` is available in the `working_set.permanent_state` also
passed to `Completer::fetch`.
# 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.
# User-Facing Changes
Less memory used, potential runtime benefits.
(Too late in the evening to run the benchmarks myself right now)
# Description
This PR is a continuation of #12629 and meant to address [Reilly's
stated
issue](https://github.com/nushell/nushell/pull/12629#issuecomment-2099660609).
With this PR, nushell should work more consistently with WezTerm on
Windows. However, that means continued scrolling with typing if osc133
is enabled. If it's possible to run WezTerm inside of vscode, then
having osc633 enabled will also cause the display to scroll with every
character typed. I think the cause of this is that reedline paints the
entire prompt on each character typed. We need to figure out how to fix
that, but that's in reedline.
For my purposes, I keep osc133 and osc633 set to true and don't use
WezTerm on Windows.
Thanks @rgwood for reporting the issue. I found several logic errors.
It's often good to come back to PRs and look at them with fresh eyes. I
think this is pretty close to logically correct now. However, I'm
approaching burn out on ansi escape codes so i could've missed
something.
Kudos to [escape-artist](https://github.com/rgwood/escape-artist) for
helping me debug an ansi escape codes that are actually being sent to
the terminal. It was an invaluable tool.

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.
# Description
Does some misc changes to `ListStream`:
- Moves it into its own module/file separate from `RawStream`.
- `ListStream`s now have an associated `Span`.
- This required changes to `ListStreamInfo` in `nu-plugin`. Note sure if
this is a breaking change for the plugin protocol.
- Hides the internals of `ListStream` but also adds a few more methods.
- This includes two functions to more easily alter a stream (these take
a `ListStream` and return a `ListStream` instead of having to go through
the whole `into_pipeline_data(..)` route).
- `map`: takes a `FnMut(Value) -> Value`
- `modify`: takes a function to modify the inner stream.

This is a rewrite for some parts of the recursive completion system. The
Rust `std::path` structures often ignores things like a trailing `.`
because for a complete path, it implies the current directory. We are
replacing the use of some of these structs for Strings.
A side effect is the slashes being normalized in Windows. For example if
we were to type `foo/bar/b`, it would complete it to `foo\bar\baz`
because a backward slash is the main separator in windows.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

Relative paths are preserved. `..`s in the paths won't eagerly show
completions from the parent path. For example, `asd/foo/../b` will now
complete to `asd/foo/../bar` instead of `asd/bar`.

This touches many tests purely in changing from owned to borrowed/static
data
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.

# Description
Removes lazy records from the language, following from the reasons
outlined in #12622. Namely, this should make semantics more clear and
will eliminate concerns regarding maintainability.
# User-Facing Changes
- Breaking change: `lazy make` is removed.
- Breaking change: `describe --collect-lazyrecords` flag is removed.
- `sys` and `debug info` now return regular records.
# After Submitting
- Update nushell book if necessary.
- Explore new `sys` and `debug info` APIs to prevent them from taking
too long (e.g., subcommands or taking an optional column/cell-path
argument).
# 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?

# 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

# 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.

# 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
```

# Description
This breaks `nu-plugin` up into four crates:
- `nu-plugin-protocol`: just the type definitions for the protocol, no
I/O. If someone wanted to wire up something more bare metal, maybe for
async I/O, they could use this.
- `nu-plugin-core`: the shared stuff between engine/plugin. Less stable
interface.
- `nu-plugin-engine`: everything required for the engine to talk to
plugins. Less stable interface.
- `nu-plugin`: everything required for the plugin to talk to the engine,
what plugin developers use. Should be the most stable interface.
No changes are made to the interface exposed by `nu-plugin` - it should
all still be there. Re-exports from `nu-plugin-protocol` or
`nu-plugin-core` are used as required. Plugins shouldn't ever have to
use those crates directly.
This should be somewhat faster to compile as `nu-plugin-engine` and
`nu-plugin` can compile in parallel, and the engine doesn't need
`nu-plugin` and plugins don't need `nu-plugin-engine` (except for test
support), so that should reduce what needs to be compiled too.
The only significant change here other than splitting stuff up was to
break the `source` out of `PluginCustomValue` and create a new
`PluginCustomValueWithSource` type that contains that instead. One bonus
of that is we get rid of the option and it's now more type-safe, but it
also means that the logic for that stuff (actually running the plugin
for custom value ops) can live entirely within the `nu-plugin-engine`
crate.
# User-Facing Changes
- New crates.
- Added `local-socket` feature for `nu` to try to make it possible to
compile without that support if needed.

# 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.
# Description
Removes the `commandline` flags and API that was deprecated in 0.91.0
with #11877.
# User-Facing Changes
Users need to migrate to the new `commandline` subcommands introduced in
0.91.0.
# Description
So far this seems like the winner of my poll on what the name should be.
I'll take this off draft once the poll expires, if this is indeed the
winner.
# 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).
