# Description
This pull request enhances the `add_parsed_keybinding` function to
provide greater flexibility in specifying keycodes for keybindings in
Nushell. Previously, the function only supported specifying keycodes
directly through character notation (e.g., `char_e` for the character
`e`). This limited users to a small set of keybindings, especially in
scenarios where specific non-English characters were needed.
With this new version, users can also specify characters using their
Unicode codes, such as `char_u003B` for the semicolon (`;`), providing a
more flexible approach to customization, for example like this:
```nushell
{
name: move_to_line_end_or_take_history_hint
modifier: shift
keycode: char_u003B # char_;
mode: vi_normal
event: {
until: [
{ send: historyhintcomplete }
{ edit: movetolineend }
]
}
}
```
# User-Facing Changes
Added support for specifying keycodes using Unicode codes, e.g.,
char_u002C (comma - `,`):
```nushell
{
name: <command_name>, # name of the command
modifier: none, # key modifier
keycode: char_u002C, # Unicode code for the comma (',')
mode: vi_normal, # mode in which this binding should work
event: {
send: <action> # action to be performed
}
}
```

Maybe we can deprecate `encode new-base64` and `decode new-base64`
first, to make the code clean and simple I'd rather remove the old
`encode base64` and `decode base64` and replace them with the `*
new-base64` commands.

It's a breaking change
# Description
After a `use std *`, the environment variables exported from the
submodules' `export-env` blocks are not available because of #13403.
This causes failures in `log` (currently) and will cause issues in
`dirs` once we stop autoloading it separately.
When the submodules are loaded separately (e.g., `use std/log`),
everything already worked correctly. While this is the preferred way of
doing it, we also want `use std *` to work properly.
This is a workaround for the standard library submodules. It is
definitely not ideal, but it can be removed when and if #13403 is fixed.
For now, we need to duplicate any environment settings in both the
submodules (when loaded with `use std/log`) and in the standard library
itself (when loaded with `use std *`). Again, this should not be
necessary, but currently is because of #13403.

This pr does two optimization for the completer:
- Switch `sort_by` to `sort_unstable_by` on `sort_completions` function
since it reduces memory allocation and the orders of the identical
completions are not matter.
- Change `prefix` type from `Vec<u8>` to `&[u8]` to reduce cloning and
memory.

Fxes https://github.com/nushell/nupm/issues/102
Not loading `std` at startup has caused an issue with nupm and std where
the `dirs` module name clashes and nupm won't load. This was technically
a preexisting bug that was previously masked. This could have been fixed
(and also should be) by changing the import statement in nupm, but the
potential for collision would remain in other (user) modules.
This PR explicitly sets the relative path for the import statements in
`std/mod.nu` so that there are no collisions.

Hi there;
I do think it must be fixed.
I also did improve performance for a fraction in case of header on
border.
I want to believe :) I didn't bench it.
But we didn't cached the width in this code branch before.
Which was causing all data reestimation.

Original stated it filled on the left to a width of 5 while showing the
command and output to fill on both sides to a width of 10. Changed
wording of description to match effect of example and displayed result.

Updated summary for commit
[612e0e2](612e0e2160)
- While folks are welcome to read through the entire comments, the core
information is summarized here.
# Description
This PR drastically improves startup times of Nushell by only parsing a
single submodule of the Standard Library that provides the `banner` and
`pwd` commands. All other Standard Library commands and submodules are
parsed when imported by the user. This cuts startup times by more than
60%.
At the moment, we have stopped adding to `std-lib` because every
addition adds a small amount to the Nushell startup time.
With this change, we should once again be able to allow new
functionality to be added to the Standard Library without it impacting
`nu` startup times.
# User-Facing Changes
* Nushell now starts about 60% faster
* Breaking change: The `dirs` (Shells) aliases will return a warning
message that it will not be auto-loaded in the following release, along
with instructions on how to restore it (and disable the message)
* The `use std <submodule> *` syntax is available for convenience, but
should be avoided in scripts as it parses the entire `std` module and
all other submodules and places it in scope. The correct syntax to
*just* load a submodule is `use std/<submodule> *` (asterisk optional).
The slash is important. This will be documented.
* `use std *` can be used for convenience to load all of the library but
still incurs the full loading-time.
* `std/dirs`: Semi-breaking change. The `dirs` command replaces the
`show` command. This is more in line with the directory-stack
functionality found in other shells. Existing users will not be impacted
by this as the alias (`shells`) remains the same.
* Breaking-change: Technically a breaking change, but probably only
impacts maintainers of `std`. The virtual path for the standard library
has changed. It could previously be imported using its virtual path (and
technically, this would have been the correct way to do it):
```nu
use NU_STDLIB_VIRTUAL_DIR/std
```
The path is now simply `std/`:
```nu
use std
```
All submodules have moved accordingly.
# Timings
Comparisons below were made:
* In a temporary, clean config directory using `$env.XDG_CONFIG_HOME =
(mktemp -d)`.
* `nu` was run with a release build
* `nu` was run one time to generate the default `config.nu` (etc.) files
- Otherwise timings would include the user-prompt
* The shell was exited and then restarted several times to get timing
samples
(Note: Old timings based on 0.97 rather than 0.98, but in the range of
being accurate)

*These last two timings point to the opportunity for further
optimization (see comment in thread below (will link once I write it).*
# Implementation details for future maintenance
* `use std banner` is a ridiculously deceptive call. That call parses
and imports *all* of `std` into scope. Simply replacing it with `use
std/core *` is essentially what saves ~14-15ms. This *only* imports the
submodule with the `banner` and `pwd` commands.
* From the code-comments, the reason that `NU_STDLIB_VIRTUAL_DIR` was
used as a prefix was so that there wouldn't be an issue if a user had a
`./std/mod.nu` in the current directory. This does **not** appear to be
an issue. After removing the prefix, I tested with both a relative
module as well as one in the `$env.NU_LIB_DIRS` path, and in all cases
the *internal* `std` still took precedence.
* By removing the prefix, users can now `use std` (and variants) without
requiring that it already be parsed and in scope.
* In the next release, we'll stop autoloading the `dirs` (shells)
functionality. While this only costs an additional 1-1.5ms, I think it's
better moved to the `config.nu` where the user can optionally remove it.
The main reason is its use of aliases (which have also caused issues) -
The `n`, `p`, and `g` short-commands are valuable real-estate, and users
may want to map these to something else.
For this release, there's an `deprecated_dirs` module that is still
autoloaded. As with the top-level commands, use of these will give a
deprecation warning with instructions on how to handle going forward.
To help with this, moved the aliases to their own submodule inside the
`dirs` module.
* Also sneaks in a small change where the top-level `dirs` command is
now the replacement for `dirs show`
* Fixed a double-import of `assert` in `dirs.nu`
* The `show_banner` step is replaced with simply `banner` rather than
re-importing it.
* A `virtual_path` may now be referenced with either a forward-slash or
a backward-slash on Windows. This allows `use std/<submodule>` to work
on all platforms.
# Performance side-notes:
* Future parsing and/or IR improvements should improve performance even
further.
* While the existing load time penalty of `std-lib` was not noticeable
on many systems, Nushell runs on a wide-variety of hardware and OS
platforms. Slower platforms will naturally see a bigger jump in
performance here. For users starting multiple Nushell sessions
frequently (e.g., `tmux`, Zellij, `screen`, et. al.) it is recommended
to keep total startup time (including user configuration) under ~250ms.
# Tests + Formatting
* All tests are green
* Updated tests:
- Removed the test that confirmed that `std` was loaded (since we
don't).
- Removed the `shells` test since it is not autoloaded. Main `dirs.nu`
functionality is tested through `stdlib-test`.
- Many tests assumed that the library was fully loaded, because it was
(even though we didn't intend for it to be). Fixed those tests.
- Tests now import only the necessary submodules (e.g., `use
std/assert`, rather than `use std assert`)
- Some tests *thought* they were loading `std/log`, but were doing so
improperly. This was masked by the now-fixed "load-everything-into-scope
bug". Local CI would pass due the `$env.NU_LOG_<...>` variables being
inherited from the calling process, but would fail in the "clean" GitHub
CI environment. These tests have also been fixed.
* Added additional tests for the changes

# Description
In the PR #13832 I used some newtypes for the old IDs. `SpanId` and
`RegId` already used newtypes, to streamline the code, I made them into
the same style as the other marker-based IDs.
Since `RegId` should be a bit smaller (it uses a `u32` instead of
`usize`) according to @devyn, I made the `Id` type generic with `usize`
as the default inner value.
The question still stands how `Display` should be implemented if even.
# User-Facing Changes
Users of the internal values of `RegId` or `SpanId` have breaking
changes but who outside nushell itself even uses these?
# After Submitting
The IDs will be streamlined and all type-safe.

# Description
This PR is related #11950 and serves as another potential fix alongside
rolling it back with https://github.com/nushell/nushell/pull/13959. The
idea here is to try and properly setup the input and output console
modes. I searched through a log of GitHub code to come up with this,
including deno, wezterm, conpty, among others. It seems to work but it
would be great if someone else would be able to test. I added comments
from the consoleapi.h from windows to know what the other flags are in
case we need to make other changes.

# Description
In this PR I replaced most of the raw usize IDs with
[newtypes](https://doc.rust-lang.org/rust-by-example/generics/new_types.html).
Some other IDs already started using new types and in this PR I did not
want to touch them. To make the implementation less repetitive, I made
use of a generic `Id<T>` with marker structs. If this lands I would try
to move make other IDs also in this pattern.
Also at some places I needed to use `cast`, I'm not sure if the type was
incorrect and therefore casting not needed or if actually different ID
types intermingle sometimes.
# User-Facing Changes
Probably few, if you got a `DeclId` via a function and placed it later
again it will still work.
# Description
Old code was comparing remaining positional arguments with total number
of arguments, where it should've compared remaining positional with
with remaining arguments of any kind. This means that if a function was
given too few arguments, `calculate_end_span` would believe that it
actually had too many arguments, since after parsing the first few
arguments, the number of remaining arguments needed were fewer than the
*total* number of arguments, of which we had used several.

## Bonus
It also improves the error handling on missing positional arguments
before keywords (no longer crashing since #9851). Instead of just giving
the keyword to the parser for the missing positional, we give an
explicit error about a missing positional argument. I would like better
descriptions than "missing var_name" though, but I'm not sure if that's
available without

This PR sets the current working directory to the location of the
Nushell executable at startup, using `std::env::set_current_dir()`. This
is desirable because after PR
https://github.com/nushell/nushell/pull/12922, we no longer change our
current working directory even after `cd` is executed, and some OS might
lock the directory where Nushell started.
The location of the Nushell executable is chosen because it cannot be
removed while Nushell is running anyways, so we don't have to worry
about OS locking it.
This PR has the side effect that it breaks buggy command even harder.
I'll keep this PR as a draft until these commands are fixed, but it
might be helpful to pull this PR if you're working on fixing one of
those bugs.

This PR updates the `folder_depth` algorithm in order to make `glob` a
bit faster. The algorithm works like this. Since `folder_depth` is
always used we need to set it to a value. If the glob pattern contains
`**` then make `folder_depth` `usize::MAX`. If `--depth` is not
provided, make it 1, otherwise use the provided value.

# Description
This PR tries to allow the `ls` command to use multiple threads if so
specified. The reason why you'd want to use threads is if you notice
`ls` taking a long time. The one place I see that happening is from WSL.
I'm not sure how real-world this test is but you can see that this
simple `ls` of a folder with length takes a while 9366 ms. I've run this
test many times and it ranges from about 15 seconds to about 10 seconds.
But with the `--threads` parameter, it takes less time, 2744ms in this
screenshot.
The only way forward I could find was to _always_ use threading and
adjust the number of threads based on if the user provides a flag. That
seemed the easiest way to do it after applying @devyn's interleave
advice.
No feelings hurt if this doesn't land. It's more of an experiment but I
think it has potential.

# Description
hi hi, this makes the parsing of modifier key combos in config more
general, and adds support for additional kitty keyboard protocol
modifiers. It seems that support for [kitty
keys](https://sw.kovidgoyal.net/kitty/keyboard-protocol) had already
been added to nushell in https://github.com/nushell/nushell/pull/10540,
and this was the only missing piece to making them available in
keybindings.
# User-Facing Changes
- keybindings in config can include the super, hyper and meta modifiers
(e.g. `modifier: super`, `modifier: shift_super`, etc.), and these
modifiers will work in supporting terminals (kitty, foot, wezterm,
alacritty...)
- all permutations of snake_cased modifier combinations now behave
equivalently for the purpose of describing keybindings in config (e.g.
`control_alt_shift` was previously supported where `shift_control_alt`
was a config error — now they're the same)
# Tests
None of this looks to be tested at the moment. I only found a smoke test
under the nu-cli crate, and I couldn't break tests elsewhere by stuffing
around with modifier handling. Works on my machine, though! ✨🌈
# Description
Instead of handling a foreground process being stopped in any way, we
were simply ignoring SIGTSTP (which the terminal usually sends to the
foreground process group when Ctrl-Z is pressed), and propagating this
to our foreground children. This works for most processes, but it
generally fails for applications which put the terminal in raw mode[1]
and implement their own suspension mechanism (typically TUI apps like
helix[2], neovim[3], top[4] or amp[5]). In these cases, triggering
suspension within the app results in the terminal getting blocked, since
the application is waiting for a SIGCONT, while nushell is waiting for
it to exit.
Fix this by unblocking SIGTSTP for our foreground children (neovim,
helix and probably others send this to themselves while trying to
suspend), and displaying the following message whenever one of them gets
stopped:
nushell currently does not support background jobs
press any key to continue
Pressing any key will then send SIGCONT to the child's process group and
resume waiting.
This fix is probably going to be superseded by a proper background job
implementation (#247) at some point, but for now it's better than
completely blocking the terminal.

# User-Facing Changes

`into value` isn't classified with `conversions` like the other `into
...` subcommands. I think this is correct, since it's a `table->table`
operation, so it's a filter that has the side effect of (potentially)
converting (via inference) cell values.
But we should at least have some search terms that help here, so this PR
adds *"conversion"* and *"convert"* to the command.

Added some tests to cover the behavior
# Description
Partialy addresses #13868. `try` does not catch non-zero exit code
errors from the last command in a pipeline if the result is assigned to
a variable using `let` (or `mut`).
This was fixed by adding a new `OutDest::Value` case. This is used when
the pipeline is in a "value" position. I.e., it will be collected into a
value. This ended up replacing most of the usages of `OutDest::Capture`.
So, this PR also renames `OutDest::Capture` to `OutDest::PipeSeparate`
to better fit the few remaining use cases for it.

# Description
Add content type metadata to the output of `view source`.
I've gone along with the mime type used [here][xdg], but this shouldn't
be merged until there is consensus #13858.
`to nuon`'s output has content type `application/x-nuon`
[xdg]:
https://gitlab.freedesktop.org/xdg/shared-mime-info/-/merge_requests/231
# User-Facing Changes
Combined with `metadata access`, allows richer display_output hooks.
Might be useful with other commands that make use of content_type like
the `http` commands.
# Description
This adds support for reading and writing binary types in the polars
commands.
The `BinaryOffset` type can be read into a Nushell native `Value` type
no problem, but unfortunately this is a lossy conversion, as there's
no Nushell-native semantic equivalent to the fixed size binary type
in Arrow.
# User-Facing Changes
`polars open` and `polars save` now work with binary types.
# Description
Similar to #13870 (thanks @WindSoilder), this PR adds a boolean which
determines whether to ignore any errors from an external command. This
is in order to fix#13876. I.e., `do -p` does not wait for externals to
complete before continuing.

# Description
Fixes: #12726 and #13185
Previously converting columns that contained null caused polars to force
a dtype of object even when using a schema.
Now:
1. When using a schema, the type the schema defines for the column will
always be used.
2. When a schema is not used, the previous type is used when a value is
null.
# User-Facing Changes
- The type defined by the schema we be respected when passing in a null
value `[a]; [null] | polars into-df -s {a: str}` will create a df with
an str dtype column with one null value versus a column of type object.
- *BREAKING CHANGE* If you define a schema, all columns must be in the
schema.

cause a lot of work to be lost. Often you might have multiple dataframes
in memory and you are trying one operation and lose all state.
While it possible the panic can leave things a strange state, it is
pretty unlikely as part of a polars pipeline. Most of the time polars
objects are not manipulating dataframes in memory mutability, but rather
creating a new dataframe the operations being applied. This is always
the case with a lazy pipeline. After the collect call, the original
dataframes are intact still and I haven't observed any side effects.

# Description
Fixes a bug with `set_last_error()` introduced by @IanManske not being
called during the jump to an error handler in IR eval. Without this,
`$env.LAST_EXIT_CODE` wasn't getting set in the `catch` block for an
external.
# Tests + Formatting
Added a `tests/eval` test to cover this in both IR and non-IR eval
This allows parsing of data (e.g. key-value pairs) where the last column
may contain the delimiter.
- this PR should close#13742
# Description
Adds a `--number (-n)` flag to `split column`, analogous to `split row
--number`.

Related to #11693. It looks like there is no reason for Nu shell's
`clear` to behave differently than other shells' `clear`. To improve the
UX and fulfill the user expectations, the default has been adjusted to
work the same as in other shells by clearing the scrollback buffer. For
edge cases where someone depends on the current behavior of keeping the
scrollback, a `-k` option has been added.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
- Improve the UX of `clear` by changing the default behavior to the same
as other popular shells, i.e clear scrollback by default.
- Remove `-a --all` flag, make it the default behavior to clear the
scrollback
- Add `-k --keep-scrollback` flag for backward compat to keep the
scrollback buffer

# Description
Fixes: #13460
The issue is caused by `try_exists` method on path, it will return
`Err(NotADirectory)` if user tried to check for a path under a regular
file.
To fix it, I think it's ok to use `exists` rather than `try_exists`,
although
[Path::exists()](https://doc.rust-lang.org/std/path/struct.Path.html#method.exists)
only checks whether or not a path was both found and readable. I think
it's ok, and we can add this information under `extra_description`.
# User-Facing Changes
The following code will no longer raise error:
```
touch a; 'a/b' | path exists
```
# Tests + Formatting
Added 1 test.
# Description
According to emacs doc, I think `ctrl-k` should map to `cuttolineend`.
# User-Facing Changes
`ctrl-k` will no longer cut to the end of buffer
# Description
Add `metadata access`, which allows accessing/inspecting the metadata of
a stream in a closure.
```nu
ls | metadata access {|meta|
...
}
```
- The metadata is provided as an argument to the closure, identical to
the record obtained with `metadata` command.
- `metadata access` passes its input stream into the closure as it is.
- Within the closure, both the metadata and the stream are available.
The closure may modify, collect or pass the stream as it is.
# Motivation
- Without this command, nu code can't act on metadata without losing the
stream, use cases requiring both the stream and metadata must be
implemented either as a built-in or a plugin.
- This command allows users to enhance presentation of data, similar to
`table` coloring the output of `ls`.
# Description
This PR:
- Removes the lazy_command, expr_command macros and migrates the
commands that were utilizing them.
- Removes the custom logic in DataFrameValues::is_equals to use the
polars DataFrame version of PartialEq
- Adds examples to commands that previously did not have examples or had
inadequate ones.
NOTE: A lot of examples now have a `polars sort` at the end. This is
needed due to the comparison in the result. The new polars version of
equals cares about the ordering. I removed the custom equals logic as it
causes comparisons to lock up when comparing dataframes that contain a
row that contains a list. I discovered this issue when adding examples
to `polars implode`

# Description
This fixes a couple of remaining differences between the IR evaluator's
handling of env vars and the AST evaluator's handling of env vars.
Blocker for #13718 (this is why those tests failed)
# User-Facing Changes
1. Handles checking overlays for hidden env vars properly, when getting
an env var from IR instruction
2. Updates config properly when doing `redirect_env()` (these probably
shouldn't be separate functions anyway, though, they're basically the
same. I did this because I intended to remove one, but now it's just
like that)
# Tests + Formatting
The `nu_repl` testbin now handles `NU_USE_IR` properly, so these tests
now work as expected.
# After Submitting
- [ ] check in on #13718 again
# Description
Fixes a bug in the IR for `try` to match that of the regular evaluator
(continuing from #13515):
```nushell
# without IR:
try { ^false } catch { 'caught' } # == 'caught'
# with IR:
try { ^false } catch { 'caught' } # error, non-zero exit code
```
In this PR, both now evaluate to `caught`. For the implementation, I had
to add another instruction, and feel free to suggest better
alternatives. In the future, it might be possible to get rid of this
extra instruction.
# User-Facing Changes
Bug fix, `try { ^false } catch { 'caught' }` now works in IR.
# Description
This is my first PR, and I'm looking for feedback to help me improve!
This PR fixes#13380 by expanding the path prior to parsing it.
Also I've removed some unused code in
[completion_common.rs](84e92bb02c/crates/nu-cli/src/completions/completion_common.rs
)
# User-Facing Changes
Auto-completion for "cd .../" now works by expanding to "cd ../../".
# Tests + Formatting
Formatted and added 2 tests for triple dots in the middle of a path and
at the end.
Also added a test for the expand_ndots() function.
# Description
This PR bumps our rust version from 1.78 to 1.79.0 due to the 1.81.0
release.

# Description
Previously there were no examples or explanations that you can use '*'
to select all columns. Updated description and added a new example.
# Description
This PR makes it so that non-zero exit codes and termination by signal
are treated as a normal `ShellError`. Currently, these are silent
errors. That is, if an external command fails, then it's code block is
aborted, but the parent block can sometimes continue execution. E.g.,
see #8569 and this example:
```nushell
[1 2] | each { ^false }
```
Before this would give:
```
╭───┬──╮
│ 0 │ │
│ 1 │ │
╰───┴──╯
```
Now, this shows an error:
```
Error: nu:🐚:eval_block_with_input
× Eval block failed with pipeline input
╭─[entry #1:1:2]
1 │ [1 2] | each { ^false }
· ┬
· ╰── source value
╰────
Error: nu:🐚:non_zero_exit_code
× External command had a non-zero exit code
╭─[entry #1:1:17]
1 │ [1 2] | each { ^false }
· ──┬──
· ╰── exited with code 1
╰────
```
This PR fixes#12874, fixes#5960, fixes#10856, and fixes#5347. This
PR also partially addresses #10633 and #10624 (only the last command of
a pipeline is currently checked). It looks like #8569 is already fixed,
but this PR will make sure it is definitely fixed (fixes#8569).
# User-Facing Changes
- Non-zero exit codes and termination by signal now cause an error to be
thrown.
- The error record value passed to a `catch` block may now have an
`exit_code` column containing the integer exit code if the error was due
to an external command.
- Adds new config values, `display_errors.exit_code` and
`display_errors.termination_signal`, which determine whether an error
message should be printed in the respective error cases. For
non-interactive sessions, these are set to `true`, and for interactive
sessions `display_errors.exit_code` is false (via the default config).
# Tests
Added a few tests.
# After Submitting
- Update docs and book.
- Future work:
- Error if other external commands besides the last in a pipeline exit
with a non-zero exit code. Then, deprecate `do -c` since this will be
the default behavior everywhere.
- Add a better mechanism for exit codes and deprecate
`$env.LAST_EXIT_CODE` (it's buggy).
# Description
After merging #13788, I get an error message which says that
`use_grid_icons` is invalid.
I think it's good to report the specific error, and guide user to delete
it.
# Description
The content-type was not being handled appropriately when sending
requests with a string value.
# User-Facing Changes
- Passing a string value through a pipeline with a content-type set as
metadata is handled correctly
- Passing a string value as a parameter with a content-type set as a
flag is handled correctly.
# Description
After looking at #13751 I noticed that the config setting
`use_grid_icons` seems out of place. So, I removed it from the config
and made it a parameter to the `grid` command.
# Description
This PR fixes#13732. However, I don't think it's a proper fix.
1. It doesn't really show what the problem is.
2. It kind of side-steps the error entirely.
I do think the change in span.rs may be valid because I don't think
span.end should ever be 0. In the example in 13732 the span end was
always 0 and so that made contains_span() return true, which seems like
a false positive.
The `checked_sub()` in ide.rs kind of just stops it from failing
outloud.
I'll leave it to smarter folks than me to land this if they think it's
worthy.
Discovered by @cptpiepmatz that #13749 broke the standalone check for
`nu-protocol`
Explicit use of the feature as workspace root also disables all features
for `serde`. Alternatively we could reconsider this there.
# Description
The existing code uses exact matches on content type. This can caused
things like "application/json; charset=utf-8" that contain a charset not
using send_json method.
NOTE: The charset portion in the above example would still be ignored as
we rely on serde and the client library to control the encoding, it is
still better to catch the json case.

# Description
Cleans up and refactors the config code using the `IntoValue` macro.
Shoutout to @cptpiepmatz for making the macro!
# User-Facing Changes
Should be none.
# After Submitting
Somehow refactor the reverse transformation.
Closes#13687Closes#13686
# Description
Light refactoring of `send_request `in `client.rs`. In the end there are
more lines but now the logic is more concise and facilitates adding new
conditions in the future. Unit tests ran fine and I tested a few cases
manually.
Cool project btw, I'll be using nushell from now on.
# Description
This PR allows the helper attribute `nu_value(rename = "...")` to be
used on struct fields and enum variants. This allows renaming keys and
variants just like [`#[serde(rename =
"name")]`](https://serde.rs/field-attrs.html#rename). This has no
singular variants for `IntoValue` or `FromValue`, both need to use the
same (but I think this shouldn't be an issue for now).
# User-Facing Changes
Users of the derive macros `IntoValue` and `FromValue` may now use
`#[nu_value(rename = "...")]` to rename single fields, but no already
existing code will break.

# Description
This pr addresses the comment:
https://github.com/nushell/nushell/issues/11791#issuecomment-2308384155
It's caused by if the last row have a very different format to the first
row, the value of `end_char` will exceed the `line_char_boundaries`.
Adding a guard for it should avoid such panic.
# User-Facing Changes
The following code should no longer panic:
```shell
"nu_plugin_highlight = '1.2.2+0.97.1' # A nushell plugin for syntax highlighting
trace_nu_plugin = '0.3.1' # A wrapper to trace Nu plugins
nu_plugin_bash_env = '0.13.0' # Nu plugin bash-env
nu_plugin_from_sse = '0.4.0' # Nushell plugin to convert a HTTP server sent event stream to structured data
... and 90 crates more (use --limit N to see more)" | detect columns -n --guess
```
# Tests + Formatting
Added 1 test.
# Description
This changes the behavior of `tee` to be more transparent when given a
value that isn't a list or range. Previously, anything that wasn't a
byte stream would converted to a list stream using the iterator
implementation, which led to some surprising results. Instead, now, if
the value is a string or binary, it will be treated the same way a byte
stream is, and the output of `tee` is a byte stream instead of the
original value. This is done so that we can synchronize with the other
thread on collect, and potentially capture any error produced by the
closure.
For values that can't be converted to streams, the closure is just run
with a clone of the value instead on another thread. Because we can't
wait for the other thread, there is no way to send an error back to the
original thread, so instead it's just written to stderr using
`report_error_new()`.
There are a couple of follow up edge cases I see where byte streams
aren't necessarily treated exactly the same way strings are, but this
should mostly be a good experience.
Fixes#13489.
# User-Facing Changes
Breaking change.
- `tee` now outputs and sends string/binary stream for string/binary
input.
- `tee` now outputs and sends the original value for any other input
other than lists/ranges.
# Tests + Formatting
Added for new behavior.
# After Submitting
- [ ] release notes: breaking change, command change
removing the `std` feature as well would drop some dependencies tied to
`rust_decimal` from the `Cargo.lock` but unclear to me what the actual
impact on compile times is.
We may want to consider dropping the `byte-unit` dependency altogether
as we have a significant fraction of our own logic to support the byte
units with 1024 and 1000 prefixes. Not sure which fraction is covered by
us or the dependency.
# Description
Implements `IntoValue` for `&str` and `DateTime` as well as other
nushell types like `Record` and `Closure`. Also allows `HashMap`s with
keys besides `String` to implement `IntoValue`.
# Description
This changes the serialization of custom values within the plugin
protocol to use MessagePack instead of bincode, removing the dependency
on bincode entirely.
Bincode does not seem to be very maintained anymore, and the externally
tagged enum representation doesn't seem to always work now even though
it should. Since we use MessagePack already anyway for the plugin
protocol, this seems like an obvious choice. This uses the unnamed
variant of the serialization rather than the named variant, which is
what the plugin protocol in general uses. The unnamed variant does not
include field names, which aren't really required here, so this should
give us something that's more or less as efficient as bincode is.
Should fix#13743.
# User-Facing Changes
- Will need to recompile plugins (but always do anyway)
- Doesn't technically break the plugin protocol (custom value data is a
black box / plugin implementation specific), but breaks compatibility
between `nu-plugin-engine` and `nu-plugin` so they do need to both be
updated to match.
# Tests + Formatting
All tests pass.

# User-Facing Changes

- `polars replace-all` can be used with polars expressions
# Description
`cargo` somewhat recently gained the capability to store `lints`
settings for the crate and workspace, that can override the defaults
from `rustc` and `clippy` lints. This means we can enforce some lints
without having to actively pass them to clippy via `cargo clippy -- -W
...`. So users just forking the repo have an easier time to follow
similar requirements like our CI.
## Limitation
An exception that remains is that those lints apply to both the primary
code base and the tests. Thus we can't include e.g. `unwrap_used`
without generating noise in the tests. Here the setup in the CI remains
the most helpful.
## Included lints
- Add `clippy::unchecked_duration_subtraction` (added by #12549)
# User-Facing Changes
Running `cargo clippy --workspace` should be closer to the CI. This has
benefits for editor configured runs of clippy and saves you from having
to use `toolkit` to be close to CI in more cases.
this PR should close#12168
# Description
Add `split cell-path`, inverse of `into cell-path`.
# User-Facing Changes
Currently there is no way to make use of cell-path values as a user,
other than passing them to builtin commands. This PR makes more use
cases possible.
This PR is an attempt to fix#8257 and fix#10985 (which is
duplicate-ish)
# Description
The parser currently doesn't know how to deal with colons appearing
while lexing whitespace-terminated tokens specifying a record value.
Most notably, this means you can't use datetime literals in record value
position (and as a consequence, `| to nuon | from nuon` roundtrips can
fail), but it also means that bare words containing colons cause a
non-useful error message.
`parser::parse_record` calls `lex::lex` with the `:` colon character in
the `special_tokens` argument. This allows colons to terminate record
keys, but as a side effect, it also causes colons to terminate record
*values*. I added a new function `lex::lex_n_tokens`, which allows the
caller to drive the lexing process more explicitly, and used it in
`parser::parse_record` to let colons terminate record keys while not
giving them special treatment when appearing in record values.
This PR description previously said: *Another approach suggested in one
of the issues was to support an additional datetime literal format that
doesn't require colons. I like that that wouldn't require new
`lex::lex_internal` behaviour, but an advantage of my approach is that
it also newly allows for string record values given as bare words
containing colons. I think this eliminates another possible source of
confusion.* It was determined that this is undesirable, and in the
current state of this PR, bare word record values with colons are
rejected explicitly. The better error message is still a win.
# User-Facing Changes
In addition to the above, this PR also disables the use of "special"
(non-item) tokens in record key and value position, and the use of a
single bare `:` as a record key.
Examples of behaviour *before* this PR:
```nu
{ a: b } # Valid, same as { 'a': 'b' }
{ a: b:c } # Error: expected ':'
{ a: 2024-08-13T22:11:09 } # Error: expected ':'
{ :: 1 } # Valid, same as { ':': 1 }
{ ;: 1 } # Valid, same as { ';': 1 }
{ a: || } # Valid, same as { 'a': '||' }
```
Examples of behaviour *after* this PR:
```nu
{ a: b } # (Unchanged) Valid, same as { 'a': 'b' }
{ a: b:c } # Error: colon in bare word specifying record value
{ a: 2024-08-13T22:11:09 } # Valid, same as { a: (2024-08-13T22:11:09) }
{ :: 1 } # Error: colon in bare word specifying record key
{ ;: 1 } # Error: expected item in record key position
{ a: || } # Error: expected item in record value position
```
# Tests + Formatting
I added tests, but I'm not sure if they're sufficient and in the right
place.
# After Submitting
I don't think documentation changes are needed for this, but please let
me know if you disagree.
# Description
This feature tried to connect reedline with the system clipboard for
three special bindings.
To do so it uses the `arboard` crate with heavy dependencies for the
system X or Wayland server or the Windows APIs. We had issues in the
headless CI with it and builds with musl seem to stall.
Removing it from the default build should negatively impact only a small
subset of users aware of the extra bindings. You can still use the
internal clipboard for binding based selection and the terminals extra
bindings to copy arbitrary content into the system clipboard.
For all other users it removes potential sources of failure and a whole
1 MB of release mode binary size (> 2% reduction). Furthermore a
potentially substantial attack surface for Nushell is gone for default
builds.
- Should resolve#13019
- Work in the spirit of #13603
# User-Facing Changes
The `edit` entries
`copyselectionsystem`/`copyselectionsystem`/`pastesystem` for
keybindings are gone in the default build
If you strictly depend on this behavior, you can still build with the
addition of `--features system-clipboard`

@sholderbach mentioned that I introduced `convert_case` as a dependency
while we already had `heck` for case conversion. So in this PR replaced
the use `convert_case` with `heck`. Mostly I rebuilt the `convert_case`
API with `heck` to work with it as I like the API of `convert_case` more
than `heck`.

Closes#13677
Remove the command `str deunicode`, as it has a narrow application, is
loosely defined by the data provided by the `deunicode` crate and thus a
stabilization liability post-1.0.
Furthermore the data to perform the look-up is quite substantial.
Removing the command and the `deunicode` dependency saves 0.9 MB of
binary data in release mode (~ 2% of total)
(checked via `cargo bloat --release` for a linux x86 build)

# Description
Using derived `IntoValue` and `FromValue` implementations on structs
with named fields currently produce `Value::Record`s where each key is
the key of the Rust struct. For records like the `$nu` constant, that
won't work as this record uses `kebab-case` for it's keys. To accomodate
this, I upgraded the `#[nu_value(rename_all = "...")]` helper attribute
to also work on structs with named fields which will rename the keys via
the same case conversion as the enums already have.
# User-Facing Changes
Users of these macros may choose different key styles for their in
`Value` representation.
# Tests + Formatting
I added the same test suite as enums already have and updated the traits
documentation with more examples that also pass the doc test.
# After Submitting
I played around with the `$nu` constant but got stuck at the point that
these keys are kebab-cased, with this, I can play around more with it.

This issue was reported by kira in
[Discord](https://discord.com/channels/601130461678272522/1276981416307069019).
In https://github.com/nushell/nushell/pull/13311, I accidentally made it
so that custom completions are filtered according to the user's
configured completion options (`$env.config.completions`) rather than
the completion options provided as part of the custom completions. This
PR is a quick fix for that.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
It should once again be possible to override match algorithm, case
sensitivity, and substring matching (`positional`) in custom
completions.

fdncred and I discussed this in Discord a bit and we thought it might be
better to not allow custom completions to override the user's config.
However, `positional` can't currently be set inside one's config, so you
can only do strict prefix matching, no substring matching. Another PR
could do one of the following:
- Document the fact that you can provide completion options inside
custom completions
- Remove the ability to provide completion options with custom
completions and add a `$env.config.completions.positional: true` option
- Remove the ability to provide completion options with custom
completions and add a new match algorithm `substring` (this is the one I
like most, since `positional` only applies to prefix matching anyway)
Separately from these options, we could also allow completers to specify
that they don't Nushell to do any filtering and sorting on the provided
custom completions.
Mistakes have been made. I forgot about a bunch of `todo`s in the helper
functions. So, this PR replaces them with proper errors. It also adds
tests for parse-time evaluation, because one `todo` I missed was in a
`run_const` function.
Hi there
Here I am using latest tabled.
My tests shows it does fixes panics, but I am wanna be sure.
@fdncred could you verify that it does fixes those panics/errors?

Currently the parser and the documentation generation use the signature
of the command, which means that it doesn't pick up on the changed name
of the `main` block, and therefore shows the name of the command as
"main" and doesn't find the subcommands. This PR changes the
aforementioned places to use the block signature to fix these issues.
This closes#13397. Incidentally it also causes input/output types to be
shown in the help, which is kinda pointless for scripts since they don't
operate on structured data but maybe not worth the effort to remove.

Based on the discussion in #13419.
## Description
Reworks the `decode`/`encode` commands by adding/changing the following
bases:
- `base32`
- `base32hex`
- `hex`
- `new-base64`
The `hex` base is compatible with the previous version of `hex` out of
the box (it only adds more flags). `base64` isn't, so the PR adds a new
version and deprecates the old one.
All commands have `string -> binary` signature for decoding and `string
| binary -> string` signature for encoding. A few `base64` encodings,
which are not a part of the
[RFC4648](https://datatracker.ietf.org/doc/html/rfc4648#section-6), have
been dropped.
## Example usage
```Nushell
~/fork/nushell> "string" | encode base32 | decode base32 | decode
string
```
```Nushell
~/fork/nushell> "ORSXG5A=" | decode base32
# `decode` always returns a binary value
Length: 4 (0x4) bytes | printable whitespace ascii_other non_ascii
00000000: 74 65 73 74 test
```
## User-Facing Changes
- New commands: `encode/decode base32/base32hex`.
- `encode hex` gets a `--lower` flag.
- `encode/decode base64` deprecated in favor of `encode/decode
new-base64`.

In this PR I expanded the helper attribute `#[nu_value]` on
`#[derive(FromValue)]`. It now allows the usage of `#[nu_value(type_name

I'd like to change that without having to manually implement the entire
trait on my own.

I was working with byte collections like `Vec<u8>` and
[`bytes::Bytes`](https://docs.rs/bytes/1.7.1/bytes/struct.Bytes.html),
both are currently not possible to be used directly in a struct that
derives `IntoValue` and `FromValue` at the same time. The `Vec<u8>` will
convert itself into a `Value::List` but expects a `Value::String` or
`Value::Binary` to load from. I now also implemented that it can load
from `Value::List` just like the other `Vec<uX>` versions. For further
working with byte collections the type `bytes::Bytes` is wildly used,
therefore I added a implementation for it. `bytes` is already part of
the dependency graph as many crates (more than 5000 to crates.io) use
it.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

User of `nu-protocol` as library, e.g. plugin developers, can now use
byte collections more easily in their data structures and derive
`IntoValue` and `FromValue` for it.

I added a few tests that check that these byte collections are correctly
translated in and from `Value`. They live in `test_derive.rs` as part of
the `ByteContainer` and I also explicitely tested that `FromValue` for
`Vec<u8>` works as expected.

Maybe it should be explored if `Value::Binary` should use `bytes::Bytes`
instead of `Vec<u8>`.
# Description
`bits rol` and `bits ror` were both undefined for the full byte rotates
and panicked when exceeding the byte rotation range.
`bits ror` further more produced nonsensical results by pulling bits
from the following byte instead of the preceding byte.
Those bugs are now fixed
# User-Facing Changes
Sound Nushell `IncorrectValue` error when exceeding the available bits
# Tests + Formatting

# Description
The meaning of the word usage is specific to describing how a command
function is *used* and not a synonym for general description. Usage can
be used to describe the SYNOPSIS or EXAMPLES sections of a man page
where the permitted argument combinations are shown or example *uses*
are given.
Let's not confuse people and call it what it is a description.
Our `help` command already creates its own *Usage* section based on the
available arguments and doesn't refer to the description with usage.
# User-Facing Changes
`help commands` and `scope commands` will now use `description` or
`extra_description`
`usage`-> `description`
`extra_usage` -> `extra_description`
Breaking change in the plugin protocol:
In the signature record communicated with the engine.
`usage`-> `description`
`extra_usage` -> `extra_description`

`SimplePluginCommand` and `PluginCommand`

Fixes#11267
Shifting by a `shift >= num_bits` is undefined in the underlying
operation. Previously we also had an overflow on negative shifts for the
operators `bit-shl` and `bit-shr`
Furthermore I found a severe bug in the implementation of shifting of
`binary` data with the commands `bits shl` and `bits shr`, this
categorically produced incorrect results with shifts that were not
`shift % 4 == 0`. `bits shr` also was able to produce outputs with
different size to the input if the shift was exceeding the length of the
input data by more than a byte.
# User-Facing Changes
It is now an error trying to shift by more than the available bits with:
- `bit-shl` operator
- `bit-shr` operator
- command `bits shl`
- command `bits shr`
# Tests + Formatting
Added testing for all relevant cases
# Description
The previous behaviour of `into record` on lists was to create a new
record with each list index as the key. This was not very useful for
creating meaningful records, though, and most people would end up using
commands like `headers` or `transpose` to turn a list of keys and values
into a record.
This PR changes that instead to do what I think the most ergonomic thing
is, and instead:
- A list of records is merged into one record.
- A list of pairs (two element lists) is folded into a record with the
first element of each pair being the key, and the second being the
value.
The former is just generally more useful than having to use `reduce`
with `merge` for such a common operation, and the latter is useful
because it means that `$a | zip $b | into record` *just works* in the
way that seems most obvious.
Example:
```nushell
[[foo bar] [baz quux]] | into record # => {foo: bar, baz: quux}
[{foo: bar} {baz: quux}] | into record # => {foo: bar, baz: quux}
[foo baz] | zip [bar quux] | into record # => {foo: bar, baz: quux}
```
The support for range input has been removed, as it would no longer
reflect the treatment of an equivalent list.
The following is equivalent to the old behavior, in case that's desired:
```
0.. | zip [a b c] | into record # => {0: a, 1: b, 2: c}
```
# User-Facing Changes
- `into record` changed as described above (breaking)
- `into record` no longer supports range input (breaking)
# Tests + Formatting
Examples changed to match, everything works. Some usage in stdlib and
`nu_plugin_nu_example` had to be changed.

@devyn found that https://github.com/nushell/nushell/pull/13595, which
made ranges be type-checked at parse time, introduced a bug that caused
`../foo` to be parsed as a string rather than a command call. This was
caused by `parse_range` returning a `Some` despite there being parse
errors (`/foo` doesn't match `SyntaxShape::Number`). To go back to the
old behavior, `parse_range` now returns `None` anytime there's any parse
errors met while parsing the range.
Unfortunately, this means that something like `..$foo` will be parsed as
a string if `$foo` isn't defined and as a range if it is defined. That
was the behavior before #13595, and it should probably be fixed at some
point, but I'm just trying to quickly fix the bug.
# User-Facing Changes

Fixes issue [12828](https://github.com/nushell/nushell/issues/12828).
When attempting a `polars collect` on an eager dataframe, we return
dataframe as is. However, before this fix I failed to increment the
internal cache reference count. This caused the value to be dropped from
the internal cache when the references were decremented again.
This fix adds a call to cache.get to increment the value before
returning.
# Description
Previously when nushell failed to parse the content type header, it
would emit an error instead of returning the response. Now it will fall
back to `text/plain` (which, in turn, will trigger type detection based
on file extension).
May fix (potentially) nushell/nushell#11927

# User-Facing Changes
It's now possible to fetch content even if the server returns an invalid

it's still better than not getting the response at all.

# Description
@sholderbach pointed out that I could've made this error message better.
So, here's my attempt to make it better.
This should work. I had a hard time figuring out how to trigger the
error anyway because the type checker doesn't allow "bad" parameters to
begin with.

# Description
This PR is meant to provide a more helpful error message when using http
get and the content type can't be parsed.
### Before
### After
The span isn't perfect but there's no way to get the span of the content
type that I can see.
In the middle of fixing this error, I also discovered how to fix the
problem in general. Since you can now see the error message complaining
about double quotes (char 22 at position 0. 22 hex is `"`). The fix is
just to remove all the double quotes from the content_type and then you
get this.
### After After
The discussion on Discord about this is that `--raw` or
`--ignore-errors` should eat this error and it "just work" as well as
default to text or binary when the mime parsing fails. I agree but this
PR does not implement that.

# Tests + Formatting
Fixes existing code, no new coverage. Existing code doesn't seem to be
covered, we could be it would be somewhat involved and the fix was
simple, so didn't bother..
# Description
As part of fixing https://github.com/nushell/nushell/issues/13586, this
PR checks the types of the operands when creating a range. Stuff like
`0..(glob .)` will be rejected at parse time. Additionally, `0..$x` will
be treated as a range and rejected if `x` is not defined, rather than
being treated as a string. A separate PR will need to be made to do
reject streams at runtime, so that stuff like `0..(open /dev/random)`
doesn't hang.
Internally, this PR adds a `ParseError::UnsupportedOperationTernary`
variant, for when you have a range like `1..2..(glob .)`.
# User-Facing Changes
Users will now receive an error if any of the operands in the ranges
they construct have types that aren't compatible with `Type::Number`.
Additionally, if a piece of code looks like a range but some parse error
is encountered while parsing it, that piece of code will still be
treated as a range and the user will be shown the parse error. This
means that a piece of code like `0..$x` will be treated as a range no
matter what. Previously, if `x` weren't the expression would've been
treated as a string `"0..$x"`. I feel like it makes the language less
complicated if we make it less context-sensitive.
Here's an example of the error you get:
```
> 0..(glob .)
Error: nu::parser::unsupported_operation
× range is not supported between int and any.
╭─[entry #1:1:1]
1 │ 0..(glob .)
· ─────┬─────┬┬
· │ │╰── any
· │ ╰── int
· ╰── doesn't support these values
╰────
```
And as an image:
Note: I made the operands themselves (above, `(glob .)`) be garbage,
rather than the `..` operator itself. This doesn't match the behavior of
the math operators (if you do `1 + "foo"`, `+` gets highlighted red).
This is because with ranges, the range operators aren't `Expression`s
themselves, so they can't be turned into garbage. I felt like here, it
makes more sense to highlight the individual operand anyway.
# Description
Fixes: #13253
The issue is because nushell use `parse_value` to parse named args, but
`parse_value` doesn't parse `OneOf` syntax shape.
# User-Facing Changes
`OneOf` in named args should works again.
# Tests + Formatting
I think it's hard to add a test, because nushell doesn't support `oneof`
syntax in custom command yet.

# Description
Fixes Issue #13477
This adds a check to see if a user is trying to invoke a
(non-executable) file as a command and returns a helpful error if so.
EDIT: this will not work on Windows, and is arguably not relevant there,
because of the different semantics of executables. I think the
equivalent on Windows would be if a user tries to invoke `./foo`, we
should look for `foo.exe` or `foo.bat` in the directory and recommend
that if it exists.
# User-Facing Changes
When a user invokes an unrecognized command that is the path to an
existing file, the error used to say:
`{name} is neither a Nushell built-in or a known external command`
This PR proposes to change the message to:
`{name} refers to a file that is not executable. Did you forget to to
set execute permissions?`
# Tests + Formatting
Ran cargo fmt, clippy and test on the workspace.
EDIT: added test asserting the new behavior
# Description
Something I meant to add a long time ago. We currently don't have a
convenient way to print raw binary data intentionally. You can pipe it
through `cat` to turn it into an unknown stream, or write it to a file
and read it again, but we can't really just e.g. generate msgpack and
write it to stdout without this. For example:
```nushell
[abc def] | to msgpack | print --raw
```
This is useful for nushell scripts that will be piped into something
else. It also means that `nu_plugin_nu_example` probably doesn't need to
do this anymore, but I haven't adjusted it yet:
```nushell
def tell_nushell_encoding [] {
print -n "\u{0004}json"
}
```
This happens to work because 0x04 is a valid UTF-8 character, but it
wouldn't be possible if it were something above 0x80.
`--raw` also formats other things without `table`, I figured the two
things kind of go together. The output is kind of like `to text`.
Debatable whether that should share the same flag, but it was easier
that way and seemed reasonable.

# Description
As per our Wednesday meeting, this adds a parse error when something
that would be parsed as an external call is present at the top level,
unless the head of the external call begins with a caret (to make it
explicit).
I tried to make the error quite descriptive about what should be done.
# User-Facing Changes
These now cause a parse error:
```nushell
$foo = bar
$foo = `bar`
```
These would have been interpreted as strings before this version, but
now they'd be interpreted as external calls. This behavior is consistent
with `let`/`mut` (which is unaffected by this change).
Here is an example of the error:
```
Error: × External command calls must be explicit in assignments
╭─[entry #3:1:8]
1 │ $foo = bar
· ─┬─
· ╰── add a caret (^) before the command name if you intended to run and capture its output
╰────
help: the parsing of assignments was changed in 0.97.0, and this would have previously been treated as a string.
Alternatively, quote the string with single or double quotes to avoid it being interpreted as a command name. This
restriction may be removed in a future release.
```
# Tests + Formatting
Tests added to cover the change. Note made about it being temporary.
# Description
Cleanups:
- Add "key_press" to event reading function names to match reality
- Move the relevant comment about why only key press events are
interesting one layer up
- Remove code duplication in handle_events
- Make `try_next` try harder (instead of bail on a boring event); I
think that was the original intention
- Remove recursion from `next` (I think that's clearer? but maybe just
what I'm used to)

# Description
This pull request merges `polars sink` and `polars to-*` into one
command `polars save`.
# User-Facing Changes
- `polars to-*` commands have all been replaced with `polars save`. When
saving a lazy frame to a type that supports a polars sink operation, a
sink operation will be performed. Sink operations are much more
performant, performing a collect while streaming to the file system.
This PR closes [Issue
#13482](https://github.com/nushell/nushell/issues/13482)
# Description
This PR tend to make all math function to be constant.
# User-Facing Changes
The math commands now can be used as constant methods.
### Some Example
```
> const MODE = [3 3 9 12 12 15] | math mode
> $MODE
╭───┬────╮
│ 0 │ 3 │
│ 1 │ 12 │
╰───┴────╯
> const LOG = [16 8 4] | math log 2
> $LOG
╭───┬──────╮
│ 0 │ 4.00 │
│ 1 │ 3.00 │
│ 2 │ 2.00 │
╰───┴──────╯
> const VAR = [1 3 5] | math variance
> $VAR
2.6666666666666665
```
# Tests + Formatting
Tests are added for all of the math command to test there constant
behavior.
I mostly focused on the actual user experience, not the correctness of
the methods and algorithms.
# After Submitting
I think this change don't require any additional documentation. Feel
free to correct me in this topic please.
# Description
This exposes the `LazyFrame::sink_*` functionality to allow a streaming
collect directly to the filesystem. This useful when working with data
that is too large to fit into memory.
# User-Facing Changes
- Introduction of the `polars sink` command
# Description
Prior this pull request `polars first` and `polars last` would collect a
lazy frame into an eager frame before performing operations. Now `polars
first` will to a `LazyFrame::limit` and `polars last` will perform a
`LazyFrame::tail`. This is really useful in working with very large
datasets.
# Description
When opening a dataframe the default operation will be to create a lazy
frame if possible. This works much better with large datasets and
supports hive format.
# User-Facing Changes
- `--lazy` is nolonger a valid option. `--eager` must be used to
explicitly open an eager dataframe.

# Description
This PR expands on [the relay of signals to running plugin
processes](https://github.com/nushell/nushell/pull/13181). The Ctrlc
relay has been generalized to SignalAction::Interrupt and when
reset_signal is called on the main EngineState, a SignalAction::Reset is
now relayed to running plugins.
# User-Facing Changes
The signal handler closure now takes a `signals::SignalAction`, while
previously it took no arguments. The handler will now be called on both
interrupt and reset. The method to register a handler on the plugin side
is now called `register_signal_handler` instead of
`register_ctrlc_handler`
[example](https://github.com/nushell/nushell/pull/13510/files#diff-3e04dff88fd0780a49778a3d1eede092ec729a1264b4ef07ca0d2baa859dad05L38).
This will only affect plugin authors who have started making use of
https://github.com/nushell/nushell/pull/13181, which isn't currently
part of an official release.
The change will also require all of user's plugins to be recompiled in
order that they don't error when a signal is received on the
PluginInterface.

# User-Facing Changes
- Content of files can be directly piped into commands like `http post`
with the content type set appropriately when using `--raw`.
# Description
When using a format string, `into datetime` would disallow an `int` even
when it logically made sense. This was mainly a problem when attempting
to convert a Unix epoch to Nushell `datetime`. Unix epochs are often
stored or returned as `int` in external data sources.
```nu
1722821463 | into datetime -f '%s'
Error: nu:🐚:only_supports_this_input_type
× Input type not supported.
╭─[entry #3:1:1]
1 │ 1722821463 | into datetime -f '%s'
· ─────┬──── ──────┬──────
· │ ╰── only string input data is supported
· ╰── input type: int
╰────
```
While the solution was simply to `| to text` the `int`, this PR handles
the use-case automatically.
Essentially a ~5 line change that just moves the current parsing to a
closure that is called for both Strings and Ints-converted-to-Strings.
# User-Facing Changes

# Description
Part 4 of replacing std::path types with nu_path types added in
https://github.com/nushell/nushell/pull/13115. This PR migrates various
tests throughout the code base.
In some `if let`s we ran the `SharedCow::to_mut` for the test and to get
access to a mutable reference in the happy path. Internally
`Arc::into_mut` has to read atomics and if necessary clone.
For else branches, where we still want to modify the record we
previously called this again (not just in rust, confirmed in the asm).
This would have introduced a `call` instruction and its cost (even if it
would be guaranteed to take the short path in `Arc::into_mut`).
Lifting it get's rid of this.
# Description
Since we make the promise that record keys/columns are exclusice we
don't have to go through all columns after we have found the first one.
Should permit some short-circuiting if the column is found early.

Original implementation contains multiple `expect` which can cause
internal runtime panic.
This pr forks the `css` selector impl and make it return an error that
nushell can recognize.
**Note:** The original impl is still used in pre-defined selector
implementations, but they
should never fail, so the `css` fn is preserved.
Closes#13496.

This is mainly cleanup, but introduces a slight (positive, if anything)
behavior change:
Some menu layouts support only a subset of styles, but with this change
the user will still be able to configure them. This seems strictly
better - if reedline starts supporting one of the existing styles for a
particular layout, there won't be any need to update nushell code.

# Description
Minor nitpicks, but the `random int` help and examples were a bit
ambiguous in several aspects. Updated to clarify that:
* An unconstrained `random int` returns a non-negative integer. That is,
the smallest potential value is 0. Technically integers include negative
numbers as well, and `random int` will never return one unless you pass
it a range with a negative lower-bound.
* To that end, changed the final example to demonstrate a negative
lower-bound.
* The range is inclusive. While most people would probably assume this,
the changes make this explicit in the examples and argument description.

# After Submitting
N/A
- **Doccomment style fixes**
- **Forgotten stuff in `nu-pretty-hex`**
- **Don't `for` around an `Option`**

I think the suggestions here are a net positive, some of the suggestions
moved into #13498 feel somewhat arbitrary, I also raised
https://github.com/rust-lang/rust-clippy/issues/13188 as the nightly
`byte_char_slices` would require either a global allow or otherwise a
ton of granular allows or possibly confusing bytestring literals.
# Description
Fixes: #13260
When user run a command like this:
```nushell
$env.FOO = " New";
$env.BAZ = " New Err";
do -i {nu -n -c 'nu --testbin echo_env FOO; nu --testbin echo_env_stderr BAZ'} | save -a -r save_test_22/log.txt
```
`save` command sinks the output of previous commands' stderr output. I
think it should be `stderr`.
# User-Facing Changes
```nushell
$env.FOO = " New";
$env.BAZ = " New Err";
do -i {nu -n -c 'nu --testbin echo_env FOO; nu --testbin echo_env_stderr BAZ'} | save -a -r save_test_22/log.txt
```
The command will output ` New Err` to stderr.
# Tests + Formatting
Added 2 cases.
- **Suggested default impl for the new `*Stack`s**
- **Change a hashmap to make clippy happy**
- **Clone from fix**
- **Fix conditional unused in test**
- then **Bump rust toolchain**
