# Description
this PR deprecates the `std testing` module in favor of Nupm.
the plan is to simply hide the module to the user but still use it
internally when running the tests so that
- users don't start to use this module and rather focus on Nupm
- devs don't have to install anything to run the tests locally, they can
just use `toolkit test stdlib` for instance
the deprecation message will be very similar to
https://github.com/nushell/nushell/pull/11097
> **Note**
> to demonstrate that the removal of such a command from the exposed
modules of `std` will be transparent and not require the user to install
anything, i have it [prepared in a branch based on this
PR](https://github.com/amtoine/nushell/compare/deprecate-std-testing...amtoine:nushell:hide-std-testing)
> running `toolkit test stdlib` will run the standard library tests
without an issue and yet `use std testing` won't work 👌
# User-Facing Changes
`std testing run-tests` will be removed in `0.90`
# Tests + Formatting
# After Submitting
this should

# Description
this is band-aid...
but it should address the issue in
https://github.com/nushell/nushell/issues/11134 until we have a better
long-term fix for this i/o types bug 😇
# User-Facing Changes
the following will now parse and run fine
```nushell
def get-initial-commit []: nothing -> string {
^git rev-list HEAD | lines | last
}
```
# Tests + Formatting
# After Submitting
`input list` now allows all types by using `into_string`.
Custom formatting logic for records was removed.
Allow ranges as an input types.
Also made the prompt check depend on option, so `input list ""` will
have an empty prompt, while `input list` does not.

# Description
Fixes: #11153
To make sure scripts stop from running on non-zero exit code, we need to
invoke `might_consume_external_result` on
`PipelineData::ExternalStream`, so it can tell nushell if this command
exists with non-zero exit code.
And this pr also adjusts some test cases.
# User-Facing Changes

This only affects existing tests, which still pass.
Goes towards implementing #10598, which asks for a spread operator in
lists, in records, and when calling commands (continuation of #11006,
which only implements it in lists)
# Description
This PR is for adding a spread operator that can be used when building
records. Additional functionality can be added later.
Changes:
- Previously, the `Expr::Record` variant held `(Expression, Expression)`
pairs. It now holds instances of an enum `RecordItem` (the name isn't
amazing) that allows either a key-value mapping or a spread operator.
- `...` will be treated as the spread operator when it appears before
`$`, `{`, or `(` inside records (no whitespace allowed in between) (not
implemented yet)
- The error message for duplicate columns now includes the column name
itself, because if two spread records are involved in such an error, you
can't tell which field was duplicated from the spans alone
`...` will still be treated as a normal string outside records, and even
in records, it is not treated as a spread operator when not followed
immediately by a `$`, `{`, or `(`.
# User-Facing Changes
Users will be able to use `...` when building records.
```
> let rec = { x: 1, ...{ a: 2 } }
> $rec
╭───┬───╮
│ x │ 1 │
│ a │ 2 │
╰───┴───╯
> { foo: bar, ...$rec, baz: blah }
╭─────┬──────╮
│ foo │ bar │
│ x │ 1 │
│ a │ 2 │
│ baz │ blah │
╰─────┴──────╯
```
If you want to update a field of a record, you'll have to use `merge`
instead:
```
> { ...$rec, x: 5 }
Error: nu:🐚:column_defined_twice
× Record field or table column used twice: x
╭─[entry #2:1:1]
1 │ { ...$rec, x: 5 }
· ──┬─ ┬
· │ ╰── field redefined here
· ╰── field first defined here
╰────
> $rec | merge { x: 5 }
╭───┬───╮
│ x │ 5 │
│ a │ 2 │
╰───┴───╯
```

Works for all arguments and flags. Because the signature parsing doesn't
give the spans, it is flags the entire signature.
Also added a constant with reserved variable names.
Fix#11158.
Reverts nushell/nushell#10943
The current implementation of `arr_to_value` is unsound, as it allows
casts of arbitrary data to arbitrary types without being marked
`unsafe`.
The full safety requirements to perform both the cast and the following
unchecked access are not as clear that a simple change of `fn
arr_to_value` to `unsafe fn arr_to_value` could be blessed without
further investigation.

# Description
Close: #10278
This pr introduces `o>>`, `e>>`, `o+e>>` to allow redirection to append
to a file.
Examples:
```nushell
echo abc o>> a.txt
echo abc o>> a.txt
cat asdf e>> a.txt
cat asdf e>> a.txt
cat asdf o+e>> a.txt
```
~~TODO:~~
~~1. currently internal commands with `o+e>` redirect to a variable is
broken: `let x = "a.txt"; echo abc o+e> $x`, not sure when it was
introduced...~~
~~2. redirect stdout and stderr with append mode doesn't supported yet:
`cat asdf o>>a.txt e>>b.ext`~~
~~For these 2 items, I'd like to fix them in different prs.~~
Already done in this pr
# Description
This PR addresses issue with cp brough up on
[discord](https://discord.com/channels/601130461678272522/614593951969574961/1177669443917189130)
where target of cp is not correctly expanded.
If one has directory `test` with file `file.txt` in it then the
following command (in one line or inside a `do` block):
```nu
cd test; let file = 'copy.txt'; cp file.txt $file
```
will create a `copy.txt` in `.` not in `test` instead. This happens
because target of `cp` is a variable which is not expanded unlike a
string literal
# User-Facing Changes
`cp` will correctly parse realative target paths

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

Fix release and nightly build workflow:
https://github.com/nushell/nightly/issues/15
I think the `mv` command in v0.87.1 still has some bugs, when downgrade
to v0.86 everything works as expected
# Description
Fixes: #10271
Given the following script:
```shell
# test.sh
echo aaaaa
echo bbbbb 1>&2
echo cc
```
This pr makes the following command possible:
```nushell
bash test.sh err> /dev/null | lines | each {|line| $line | str length}
```
## General idea behind the change:
When nushell redirect stderr message to external file
1. it take stdout of external stream, and pass this stream to next
command, so it won't block next pipeline command from running.
2. relative stderr stream are handled by `save` command
These two streams are handled separately, so we need to delegate a
thread to `save` command, or else we'll have a chance to hang nushell,
we have meet a similar before: #5625.
### One case to consider
What if we're failed to save to an external stream? (Like we don't have
a permission to save to a file)?
In this case nushell will just print a waning message, and don't stop
the following scripts from running.
# User-Facing Changes
## Before
```nushell
❯ bash test2.sh err> /dev/null | lines | each {|line| $line | str length}
aaaaa
cc
```
## After
```nushell
❯ bash test2.sh err> /dev/null | lines | each {|line| $line | str length}
╭───┬───╮
│ 0 │ 5 │
│ 1 │ 2 │
╰───┴───╯
```
BTY, after this pr, the following commands are impossible either, it's
important to make sure that the implementation doesn't introduce too
much costs:
```nushell
❯ echo a e> a.txt e> a.txt
Error: × Can't make stderr redirection twice
╭─[entry #1:1:1]
1 │ echo a e> a.txt e> a.txt
· ─┬
· ╰── try to remove one
╰────
❯ echo a o> a.txt o> a.txt
Error: × Can't make stdout redirection twice
╭─[entry #2:1:1]
1 │ echo a o> a.txt o> a.txt
· ─┬
· ╰── try to remove one
╰────
```
# Description
Closes: #7260
About the change:
When we make an internalcall, and meet a `switch` (Flag.arg is None),
nushell will try to see if the switch is called like `--xyz=false` , if
that is true, `parse_long_flag` will return relative value.
# User-Facing Changes
So after the pr, the following would be possible:
```nushell
def build-imp [--push, --release] {
echo $"Doing a build with push: ($push) and release: ($release)"
}
def build [--push, --release] {
build-imp --push=$push --release=$release
}
build --push --release=false
build --push=false --release=true
build --push=false --release=false
build --push --release
build
```
# Tests + Formatting
Done
# After Submitting
Needs to submit a doc update, mentioned about the difference between
`def a [--x] {}` and `def a [--x: bool] {}`
# Description
Further work towards the goal that we can make `Record`'s field private
and experiment with different internal representations
## Details
- Use inplace record iter in `nu-command/math/utils`
- Guarantee that existing allocation can be reused
- Use proper record iterators in `path join`
- Remove unnecesary hashmap in `path join`
- Should minimally reduce the overhead
- Unzip records in `nu-command`
- Refactor `query web` plugin to use record APIs
- Use `Record::into_values` for `values` command
- Use `Record::columns()` in `join` instead.
- Potential minor pessimisation
- Not the hot value path
- Use sane `Record` iters in example `Debug` impl
- Avoid layout assumption in `nu-cmd-extra/roll/mod`
- Potential minor pessimisation
- relegated to `extra`, changing the representation may otherwise break
this op.
- Use record api in `rotate`
- Minor risk that this surfaces some existing invalid behavior as panics
as we now validate column/value lengths
- `extra` so things are unstable
- Remove unnecessary references in `rotate`
- Bonus cleanup

None functional, minor potential differences in runtime. You win some,
you lose some.

# Description
I'm not sure if "is-terminal" is the best name for this command as there
is also "term size". Uses
[`is_terminal()`](https://doc.rust-lang.org/stable/std/io/trait.IsTerminal.html#tymethod.is_terminal)
which is cross-platform.
Possible alternative names:
* `term is-tty --stdout`
* `term is-tty stdout`
* `term is-terminal stdout`
If multiple streams are provided an error is returned. The error span
covers all arguments as the incompatible one is not known. This may be
new?
Fixes#10517
# User-Facing Changes
* Add `is-terminal` to check if stdin, stdout, or stderr are a terminal
(TTY)
# Tests + Formatting
The nu tests always redirect stdin, stdout, and stderr so a positive
test case is not possible without extra work
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`
# After Submitting
The new command will be added automatically

This is still work in progress. But let's start somewhere.
Goal for this being in the repo is to make sure we update it more
frequently than the
https://github.com/nushell/nushell.github.io/tree/main/contributor-book
- Add folder for in-repo developer documentation
- Move PLATFORM_SUPPORT into devdocs
- Move our rust style to devdocs
- Use nushell code formatting in CONTRIBUTING
- Add FAQ file for developers with example questions
- Describe error handling best practices
# Description
`ShellError::FlagNotFound` had a note that said it may be removable so
this PR removes it instead of updating it to named fields per #10700
I can't see this error being used since it was introduced with #4364. I
can't find why or where it was used before that date, though. There was
a large merge with that PR but I can't penetrate the secrets of git to
find out where its earlier history went.

Fix the breaking changes.
Get's rid of some outdated transitive dependencies.
Sadly we need to expose more of `procfs` to `nu-command` based on how
the features of `nu-system` are exposed right now.
Conditional compilation/dependencies from hell included
Supersedes #11101
