# 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(
input: &Value,
raw: bool,
tabs: Option<usize>,
indent: Option<usize>,
span: Option<Span>,
) -> Result<String, ShellError>
```
# Tests + Formatting
i've basically taken all the tests from
`crates/nu-command/tests/format_conversions/nuon.rs` and converted them
to use `from_nuon` and `to_nuon` instead of Nushell commands
- i've created a `nuon_end_to_end` to run both conversions with an
optional middle value to check that all is fine
> **Note**
> the `nuon::tests::read_code_should_fail_rather_than_panic` test does
give different results locally and in the CI...
> i've left it ignored with comments to help future us :)

mention that in the release notes for sure!!
# 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.
# Description

About the change: it make pattern handling into a function:
`ls_for_one_pattern`(for ls), `du_for_one_pattern`(for du). Then
iterates on user input pattern, call these core function, and chaining
these iterator to one pipelinedata.
# Description
- Refactors `first` and `last` using `Vec::truncate` and `Vec::drain`.
- `std::mem::take` was also used to eliminate a few `Value` clones.
- The `NeedsPositiveValue` error now uses the span of the `rows`
argument instead of the call head span.
- `last` now errors on an empty stream to match `first` which does
error.
- Made metadata preservation more consistent.
# User-Facing Changes
Breaking change: `last` now errors on an empty stream to match `first`
which does error.
# Description
Fixes: #11996
After this change `let t = timeit ^ls` will list current directory to
stdout.

# 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.

Possibly support `get` `get`ting negative numbers, as per #12346
discussion. Alternatively, we can consider adding a cellpath for
negative indexing?
# 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.
# Description
Fixes how the directory permissions are calculated in `mkdir`. Instead
of subtraction, the umask is actually used as a mask via negation
followed by bitwise and with the default mode. This matches how [uucore
calculates](cac7155fba/src/uu/mkdir/src/mkdir.rs (L61))
the mode.
# Description
This pr is addressing feedback from
https://github.com/nushell/nushell/pull/12277#issuecomment-2027246752
Currently I think it's fine to replace `--legacy` flag with `--guess`
one. Only use `guess_width` algorithm if `--guess` is provided.
# User-Facing Changes
So it won't be a breaking change to previous version.
# 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
# Tests + Formatting
* Tests added to cover expected behavior around insertion of null values
# Description
Closes https://github.com/nushell/nushell/issues/12257
This was down to the use of `eval_block` instead of
`eval_block_with_early_return`. We may want to reconsider how we
differentiate between this behavior. We currently need to check all the
remaining commands that can invoke a closure block, if they properly
handle `ShellError::Return` as a passing of a `Value`

Regression test
# 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.

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.

# Description
Fixes: #11887Fixes: #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.

# 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`.

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.

# User-Facing Changes

# 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).
# After Submitting
The language guide and other documentation will need to be updated.
# Description
There are lots of duplicate test for `cp`, it's because we once have
`old-cp` command.
Today `old-cp` is removed, so there is no need to keep these tests.
# Description
Fixes some ignored clippy lints.
# User-Facing Changes
Changes some signatures and return types to `&dyn Command` instead of
`&Box<dyn Command`, but I believe this is only an internal change.
# 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.

# 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.

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.

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.

# Description
As title, currently on latest main, nushell confused user if it allows
implicit casting between glob and string:
```nushell
let x = "*.txt"
def glob-test [g: glob] { open $g }
glob-test $x
```
It always expand the glob although `$x` is defined as a string.
This pr implements a solution from @kubouch :
> We could make it really strict and disallow all autocasting between
globs and strings because that's what's causing the "magic" confusion.
Then, modify all builtins that accept globs to accept oneof(glob,
string) and the rules would be that globs always expand and strings
never expand
# User-Facing Changes
After this pr, user needs to use `into glob` to invoke `glob-test`, if
user pass a string variable:
```nushell
let x = "*.txt"
def glob-test [g: glob] { open $g }
glob-test ($x | into glob)
```
Or else nushell will return an error.
```
3 │ glob-test $x
· ─┬
· ╰── can't convert string to glob

The feature `sqlite` is not active by default on `nu-command`.
Only when building `cargo b --all --tests` would the feature be
activated via `nu`'s feature requirements.
Make the tests conditional
Saw this when double checking the removals from #11938.
Making sure each crate still compiles individually, ensures both that
you can run subcrate tests independently and that the `cargo publish`
run will succeed to build the crate with the default feature set (see
the problems occurring for the `0.90.0` release.
Hi there;
Sorry took that long to respond.
I guess it's good?
It will consume the whole stream whether possible.
I do believe it will be faster in WSL in general too (in a sense of
whole buffer output), but its interesting issue probably needed to be
separated. It was not very well explained as well.

This is a follow up to
https://github.com/nushell/nushell/pull/11621#issuecomment-1937484322
Also Fixes: #11838
## About the code change
It applys the same logic when we pass variables to external commands:
0487e9ffcb/crates/nu-command/src/system/run_external.rs (L162-L170)
That is: if user input dynamic things(like variables, sub-expression, or
string interpolation), it returns a quoted `NuPath`, then user input
won't be globbed
# User-Facing Changes
Given two input files: `a*c.txt`, `abc.txt`
* `let f = "a*c.txt"; rm $f` will remove one file: `a*c.txt`.
~* `let f = "a*c.txt"; rm --glob $f` will remove `a*c.txt` and
`abc.txt`~
* `let f: glob = "a*c.txt"; rm $f` will remove `a*c.txt` and `abc.txt`
## Rules about globbing with *variable*
Given two files: `a*c.txt`, `abc.txt`
| Cmd Type | example | Result |
| ----- | ------------------ | ------ |
| builtin | let f = "a*c.txt"; rm $f | remove `a*c.txt` |
| builtin | let f: glob = "a*c.txt"; rm $f | remove `a*c.txt` and
`abc.txt`
| builtin | let f = "a*c.txt"; rm ($f \| into glob) | remove `a*c.txt`
and `abc.txt`
| custom | def crm [f: glob] { rm $f }; let f = "a*c.txt"; crm $f |
remove `a*c.txt` and `abc.txt`
| custom | def crm [f: glob] { rm ($f \| into string) }; let f =
"a*c.txt"; crm $f | remove `a*c.txt`
| custom | def crm [f: string] { rm $f }; let f = "a*c.txt"; crm $f |
remove `a*c.txt`
| custom | def crm [f: string] { rm $f }; let f = "a*c.txt"; crm ($f \|
into glob) | remove `a*c.txt` and `abc.txt`
In general, if a variable is annotated with `glob` type, nushell will
expand glob pattern. Or else, we need to use `into | glob` to expand
glob pattern

# Description
Hi,
Fixes#10838, where before the `date` would be formatted incorrectly,
and was not picking `LC_TIME` for time formatting, but it picked the
first locale returned by the `sys-locale` crate instead. Now it will
format time based on `LC_TIME`. For example,
```
// my locale `nl_NL.UTF-8`
❯ date now | format date '%x %X'
20-02-24 17:17:12
$env.LC_TIME = "en_US.UTF-8"
❯ date now | format date '%x %X'
02/20/2024 05:16:28 PM
```
Note that I also changed the `default_env.nu` as otherwise the Time will
show AM/PM twice. Also reason for the `chrono` update is because this
relies on a fix to upstream repo, which i initially submitted an
[issue](https://github.com/chronotope/chrono/issues/1349#event-11765363286)

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

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.
Make sure you've run and fixed any issues with these commands:
- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use std testing; testing run-tests --path
crates/nu-std"` to run the tests for the standard library

# Description
Requires each of the rest args for `select` and `reject` to be a cell
path instead of the current `oneof(cellpath, list<cellpath>`. This
simplifies the command signatures and code for `select` and `reject`.
Users can now spread lists into the rest arguments instead of providing
them as is.
For example,
```nushell
ls | select [name size]
```
must now be
```nushell
ls | select ...[name size]
```
# User-Facing Changes
Breaking change for the `select` and `reject` command signatures.
# Description
Close: #9673Close: #8277Close: #10944
This pr introduces the following syntax:
1. `e>|`, pipe stderr to next command. Example: `$env.FOO=bar nu
--testbin echo_env_stderr FOO e>| str length`
2. `o+e>|` and `e+o>|`, pipe both stdout and stderr to next command,
example: `$env.FOO=bar nu --testbin echo_env_mixed out-err FOO FOO e+o>|
str length`
Note: it only works for external commands. ~There is no different for
internal commands, that is, the following three commands do the same
things:~ Edit: it raises errors if we want to pipes for internal
commands
```
❯ ls e>| str length
Error: × `e>|` only works with external streams
╭─[entry #1:1:1]
1 │ ls e>| str length
· ─┬─
· ╰── `e>|` only works on external streams
╰────
❯ ls e+o>| str length
Error: × `o+e>|` only works with external streams
╭─[entry #2:1:1]
1 │ ls e+o>| str length
· ──┬──
· ╰── `o+e>|` only works on external streams
╰────
```
This can help us to avoid some strange issues like the following:
`$env.FOO=bar (nu --testbin echo_env_stderr FOO) e>| str length`
Which is hard to understand and hard to explain to users.

Maybe update documentation about these syntax.
