# Description
This PR is just a quick change to add `coreutils` to the `cp` command. I
thought that it would be a good search term as we start to integrate
more `coreutils` commands.

# Description
This PR adds a new command called `debug info`. I'm not sure if the name
is right but we can rename it if needed. The purpose of this command is
to show a user how much memory nushell is using. This is what the output
looks like.
I feel like the further we go with nushell, the more we'll need to
easily monitor the memory usage. With this command, we should easily be
able to do that with scripts or just running the command.
```nushell

Fixes#10696
# Description
As reported, you could mess up the ring of remembered directories in
`std dirs` (a.k.a the `shells` commands) with a sequence like this:
```
~/test> mkdir b c
~/test> pushd b
~/test/b> cd ../c
~/test/c> goto 0
~/test> goto 1
## expect to end up in ~/test/c
## observe you're in ~/test/b
~/test/b>
```
Problem was `dirs goto` was not updating the remembered directories
before leaving the current slot for some other. This matters if the user
did a manual `cd` (which cannot update the remembered directories ring)

Re-fixes #3674, if that is seen as desirable to do.
# Description
This PR changes the implementation of the `--features=extra` string
casing commands from Inflector to `heck`, as in PR #4081. This PR landed
a long time ago, but somewhere along the way (i can't find it) the
implementation ended up being switched back to Inflector.
# User-Facing Changes
Inflector and `heck` implement casing differently, so all of the
commands have different behavior around edge cases (consecutive
capitals, interspersed numbers and letters, etc)
### Before
```nu
G:/Dev/nu-itself/nushell> [UserID ABCdefGHI foo123bar] | str camel-case
╭───┬───────────╮
│ 0 │ userID │
│ 1 │ abcdefGHI │
│ 2 │ foo123Bar │
╰───┴───────────╯
G:/Dev/nu-itself/nushell> [UserID ABCdefGHI foo123bar] | str snake-case
╭───┬─────────────╮
│ 0 │ user_id │
│ 1 │ ab_cdef_ghi │
│ 2 │ foo_12_3bar │
╰───┴─────────────╯
```
### After
```nu
G:/Dev/nu-itself/nushell> [UserID ABCdefGHI foo123bar] | str camel-case
╭───┬───────────╮
│ 0 │ userId │
│ 1 │ abCdefGhi │
│ 2 │ foo123bar │
╰───┴───────────╯
G:/Dev/nu-itself/nushell> [UserID ABCdefGHI foo123bar] | str snake-case
╭───┬─────────────╮
│ 0 │ user_id │
│ 1 │ ab_cdef_ghi │
│ 2 │ foo123bar │
╰───┴─────────────╯
```
# Tests + Formatting
The existing string casing tests pass... because none of them relied on
any of these edge cases
# Description
Open question:
Undocumented behavior for the new argument `ambiguous` to the
`as_datetime`
methods. I cheated by passing a default (assuming empty string).
This appears like an API primarily serving the python impl:
https://pola-rs.github.io/polars/py-polars/html/reference/expressions/api/polars.Expr.str.to_datetime.html#polars-expr-str-to-datetime
# User-Facing Changes
Only dependent on breaking changes to the behavior of polars.
# Tests + Formatting
No observed changes to tests
Manually checked `dfr as-datetime`, doesn't seem to panic.
# Description

# Description
This PR changes the `canonicalize_ndots` tests (renames to
canonicalize_ndots2) so that when it's checking for
`canonicalize_with("...", cwd)` it guarantees it begins in a more deeply

D:\nushell and it can't do `cd ...` from that folder.

Prompted by a question on Discord why completions may be missing.
With standard completion settings getting the subcommands doesn't seem

New command `dfr` that does nothing apart from displaying the
subcommands and hogging a space in the completions

# Description
This PR renames nushell's `cp` command to `cp-old` to make room for

`cp-old` entirely.

# Description
The issue #10318 is resolved by introducing helper methods within the
existing `get_documentation` function in the nu-engine crate. Initially,
I considered using nu-color-config crate to convert HEX config color to
ANSI color and employing the following method
[https://github.com/nushell/nushell/blob/main/crates/nu-color-config/src/color_config.rs#L9C1-L20C2](https://github.com/nushell/nushell/blob/main/crates/nu-color-config/src/color_config.rs#L9C1-L20C2).
However, this approach was deemed impractical due to circular
dependencies. Consequently, in a manner akin to how we invoke the
`table` command from the nu-command crate in `get_documentation`
function to create a themed-colored table, we invoke the `ansi` command
from nu-command to obtain the ANSI theme color code.
# User-Facing Changes
Visual Changes Only: the help command now uses configured theme, else it
falls back on default hard coded values.

This pr fix clippy warnings in latest clippy version(1.72.0):
Unfortunally it's not easy to handle for [try
fold](https://rust-lang.github.io/rust-clippy/master/index.html#/manual_try_fold)
warning in `start command`
Refer to known issue:
> This lint doesn’t take into account whether a function does something
on the failure case, i.e., whether short-circuiting will affect
behavior. Refactoring to try_fold is not desirable in those cases.
That's the case for our code, which does something on the failure case.
So this pr is making a little refactor on `try_commands`.
# Description
Relax typechecking of key-less `table`/`record`
Assume that they are acceptable for more narrowly specified
`table<...>`/`record<...>` where `...` specifies keys and potentially
types for those keys/columns.
This ensures that you can use commands that specify general return
values statically with more specific input-/args-type requirements.
Reduces the power of the type-check a bit but unlocks you to actually
use the specific annotations in more places.
Incompatibilities will only be raised if an output type declares
specific columns/keys.
Closes#9702
Supersedes #10594 as a simpler solution requiring no extra distinction.
h/t @1kinoti, @NotLebedev
# User-Facing Changes
Now legal at type-check time
```nu
def foo []: nothing -> table { [] }
def foo []: nothing -> table<> { ls }
def bar []: table<a:int,b:string> -> nothing {}
foo | bar
```
# Tests + Formatting

# Description
Fixes https://github.com/nushell/nushell/issues/10605 (again).

# Description
Closes#10537. Basically error message was unhelpful, and this temporary
measure adds back the nice previous nushell error message. Ideally, we
would like to add a more permanent solution mentioned in the issue
[comments](https://github.com/nushell/nushell/issues/10537#issuecomment-1743686122),
but since we want to have `ucp` as `cp` on new release, this is hackier
but way simpler so this fix should do it.
Only downside is that now behavior differs from `uutils` in the sense
that:
```
uutils:
> cp a foo/ bar
ls bar
# foo/a
nushell:
>ucp a foo/ bar
# directory error (not copied) ....
```
So, since its non fatal error, uutils copies a, but nushell errors out
with nothing copied. If we go to option 3 mentioned above, then we can
decide what we want to do, and perhaps continue on a non fatal error.

# Description
To my knowledge `type@completer` annotations only make sense in
arguments at the moment.
Restrict the parsing.
Also fix a bug in parsing the completer annotation should there be more
than 1 `@`
- Add test that we disallow completer in type
- Guard against `@` inside command name
- Disallow custom completers in type specification
# User-Facing Changes

Tests to verify the error message
Implemented URL decoding as a url subcommand, created corresponding unit
tests. The logic, examples and descriptions were based on the existing
`url encode` command.
Resolves#10563
# Description
Added a new `url decode` command to compliment the existing `url
encode`, as proposed by myself in #10563.
It takes a string, list of strings or cell path and produces the
corresponding decoded strings.
# User-Facing Changes
New url subcommand `url decode`, as described above.
# Tests + Formatting
I've added unit tests for the new subcommand and ensured all actions
outlined below showed no issues.

# Description
This PR removes the underline from the log format. It's been messing

therefore everything after it is underlined.

Reverts nushell/nushell#10596
Using the long option in examples is going to be confusing as it makes
the reader think the long option is required. It also isn't idiomatic
Nushell.
The examples should be copy-paste-able as idiomatic Nushell, so as such
we shouldn't expand them to the long flag name.

# Description
"can't follow stream paths" errors have always been a bit scary and
obnoxious because they give no information about what happens...
in this PR i try to slightly improve the error message by telling if the
stream was empty or not and give span information when available.

# Description
When referring to the type use `int` consistently. Only when referring
to the concept of integer numbers use `integer`.
- Fix `random integer` to `random int` tests
- Forgot in #10520
- Use int instead of integer in error messages
- Use int type name in bits commands
- Fix messages in `for` examples
- Use int typename in `into` commands
- Use int typename in rest of commands
- Report errors in `nu-protocol` with int typename
Work for #10332
# User-Facing Changes
User errorrs should now use `int` so you can easily find the necessary
commands or type annotations.
# Tests + Formatting
Only two tests found that needed updating
code cleanup of *eval.rs*
I was reviewing the engine code and noticed this...
The *eval_element_with_input* method in eval.rs does not need to be
public at the moment
because no one is calling it...
@jntrnr is making this method not public going to block someone in the
future who might need it ?
Right now its not being used so I decided to tighten up the API a bit...
# Description
This removes the old style "cd with abbreviations" that would attempt to
guess what directory you wanted to `cd` to. This would sometimes have
false positives, so we left it off by default in the config.
In the current main, we have much-improved path completions
(https://github.com/nushell/nushell/pull/10543) so you can now do `cd
a/b<tab>` and get a much better experience (because you can see the
directory you're about to cd to). This removes the need for the previous
abbreviation system.
# User-Facing Changes
This does remove the old abbreviation system. It will likely mean that
old config files that have settings for abbreviations will now get
errors.
update: here's an example of the error you'll see:

Adds warning to `url join` when input key is not supported as suggested
by @amtoine in #10506.

- #10283
# Description
even though it appears defining `to foo` does not allow to do `save
x.foo` for free (see https://github.com/nushell/nushell/issues/10429),
because #10283 did add `from ndjson` and `from jsonl` to the standard
library, i thought adding their `to ...` counterpart would make sense
😋
# User-Facing Changes
users can now convert structured data back to NDJSON and JSONL 👌
# Tests + Formatting
this PR adds the exact same tests as for the `from ...` commands
- structured data is in `result` and the string is now the expected
- the two invalid `from ...` tests cannot be reproduced for `to ...`

# After Submitting
Remove code for 2 no-longer-used configuration options in `explore`:
`explore.config.cursor_color` and `explore.config.border_color`.
Think I made these unnecessary in
https://github.com/nushell/nushell/pull/10533 and
https://github.com/nushell/nushell/pull/10270 but missed this code, my
bad. The `explore` config code is a little hard to follow because it
does so many key lookups in hashmaps.
# Description
Retrieving tests and their annotation no longer uses nu --ide-ast
spawned in a subprocess which should reduce test runner startup time.
# User-Facing Changes
# Tests + Formatting
# After Submitting
This PR removes the `line_head_top`, `line_head_bottom`, `line_shift`,
and `line_index` configuration options from `explore`. These were
previously used to control whether the horizontal+vertical lines in this
`ls | explore -i` screenshot would be displayed:
Now, all lines are displayed (same as the previous default config
values) and this is no longer configurable.
## Context
I'm continuing to chip away at `explore` when I have time. I have a
long-term goal to make `explore` simpler for users+developers. For now
I'm mostly making small incremental changes where I find underused
functionality+configuration and remove it; hopefully eventually this
will make it easier to make larger changes.
I found these specific config options a little hard to understand when
reading `explore` code, and when reading `config.nu` as a user their
behaviour+naming is not obvious. I also think that in the long term,
`explore` styling should inherit most styling from `table` instead of
having its own styling system.
The value rendering code in explore is _very_ flexible; values can be
rendered with orientation `Top`, `Left`, `Bottom`, or `Right`. The
default is `Top` for tables (header at the top) and `Left` for records
(header on the left).
This PR removes `Bottom` and `Right`; they are largely untested,
probably used by nobody, and they complicate the rendering code.
## Testing Performed
I've manually confirmed that tables and records still render the same
ass before, and the `t`/transpose command still works.

> [!NOTE]
> This PR description originally used examples where the `generator`
closure returned a list. It has since been updated to use records
instead.
The `unfold` command allows users to dynamically generate streams of
data. The stream is generated by repeatedly invoking a `generator`
closure. The `generator` closure accepts a single argument and returns a
record containing two optional keys: 'out' and 'next'. Each invocation,
the 'out' value, if present, is added to the stream. If a 'next' key is
present, it is used as the next argument to the closure, otherwise
generation stops.
The name "unfold" is borrowed from other functional-programming
languages. Whereas `fold` (or `reduce`) takes a stream of values and
outputs a single value, `unfold` takes a single value and outputs a
stream of values.
### Examples
A common example of using `unfold` is to generate a fibbonacci sequence.
See
[here](6ffdac103c/src/sources.rs (L65))
for an example of this in rust's `itertools`.
```nushell
> unfold [0, 1] {|fib| {out: $fib.0, next: [$fib.1, ($fib.0 + $fib.1)]} } | first 10
───┬────
0 │ 0
1 │ 1
2 │ 1
3 │ 2
4 │ 3
5 │ 5
6 │ 8
7 │ 13
8 │ 21
9 │ 34
───┴────
```
This command is particularly useful when consuming paginated APIs, like
Github's. Previously, nushell users might use a loop and buffer
responses into a list, before returning all responses at once. However,
this behavior is not desirable if the result result is very large. Using
`unfold` avoids buffering and allows subsequent pipeline stages to use
the data concurrently, as it's being fetched.
#### Before
```nushell
mut pages = []
for page in 1.. {
let resp = http get (
{
scheme: https,
host: "api.github.com",
path: "/repos/nushell/nushell/issues",
params: {
page: $page,
per_page: $PAGE_SIZE
}
} | url join)
$pages = ($pages | append $resp)
if ($resp | length) < $PAGE_SIZE {
break
}
}
$pages
```
#### After
```nu
unfold 1 {|page|
let resp = http get (
{
scheme: https,
host: "api.github.com",
path: "/repos/nushell/nushell/issues",
params: {
page: $page,
per_page: $PAGE_SIZE
}
} | url join)
if ($resp | length) < $PAGE_SIZE {
{out: $resp}
} else {
{out: $resp, next: ($page + 1)}
}
}
```

# Description
Fixes: #7085
Also closes: #7526
# User-Facing Changes
After this change, we need to use `-c` flag like this:
```nushell
[[a, b, c]; [1, 2, 3]] | rename -c { a: ham }
```
But we can rename many columns easily, here is another example:
```nushell
[[a, b, c]; [1, 2, 3]] | rename -c { a: ham, b: ham2 }
```

# Description
Closes#10441
Uses `String::to_lowercase()` when the file's extension `ext` is parsed
to allow `from_decl(format!("from {ext}"))` to return the desired output
regardless of extension case.
It doesn't work with sqlite files since those are handled earlier in the
parsing but I think is good- since there's no standard file extension
used by sqlite so a user will likely want case sensitivity in that case.
This also has the (possibly undesired) effect of making `open`
completely case insensitive, e.g. `open foo.JSON` will work on a file
named `foo.json` and vice versa. This is good on Windows as it treats
`foo.json` and `foo.JSON` as the same file, but may not be the desired
behaviour on Unix.
If this behaviour is undesired I assume it would be fixed with a
`#[cfg(not(unix))]` attribute on the `to_lowercase()` operation but that
produces slightly "uglier" code that I didn't wish to submit unless
necessary.
old behaviour:
new behaviour:

This pr closes#10521.
# Description
The default prompt by nushell will replace `$nu.home-path` with `~`.
E.g. for a user named `user`, `/home/user` would become `~`. This also
works with sub paths, e.g. `/home/user/docs` would become `~/docs`.
The issue is that this replacement was a tad overzealous. A path like
`/home/user-with-suffix` would become `~-with-suffix`. This PR fixes the
issue by updating the home path detection logic.
# User-Facing Changes
The bugged behavior no longer occurs.
# Tests + Formatting
* `cargo` checks were not performed as this does not touch rust.
* The updated logic was tested against
[elvish](https://github.com/elves/elvish)'s path replacement logic, for
~10,000 randomly selected folders on a linux server. All paths were
processed the same.

# User-Facing Changes
You can now either pass a string with the name of the executable or a
list with the executable and any flags to
`$env.config.buffer_editor`/`$env.EDITOR`/`$env.VISUAL`
Both the external buffer editor of reedline (by default bound to
`Ctrl-o`) and the commands `config nu` and `config env` will respect
those variables in the following order:
1. `$env.config.buffer_editor`
2. `$env.EDITOR`
3. `$env.VISUAL`
Example:
```
$env.EDITOR = "nvim" # The system-wide EDITOR is neovim
$env.config.buffer_editor = ["vim" "-p2"] # Force vim to open two tabs (not particularly useful)
$env.config.buffer_editor = null # Unset `buffer_editor` -> Uses `$env.EDITOR` ergo nvim

# Description
Support keyboard enhancement protocol as implemented by Kitty console,
hence Kitty protocol.
This PR enables Nushell to use keybinding that is not available before,
such as Ctrl+i (that alias to Tab) or Ctrl+e (that alias to Esc, likely
I mistaken). After this PR merged and you set `use_kitty_protocol`
enabled, if your console app support Kitty protocol (WezTerm, Kitty,
etc.) you will be able to set more fine-grained keybinding.
For Colemak users, this feature is a blessing, because some Ctrl+[hjkl]
that previously unmap-able to Ctlr+[hnei] now it is.
# User-Facing Changes
This adds `use_kitty_protocol` config which defaults to false. When set
to `true`, it enables kitty protocol on the line editor when supported,
or else it warns.

More incremental `explore` improvements!
This PR removes the `show_cursor` config from the `explore` command, in
favour of always using the background colour to highlight the selected
cell. I believe this is a better default and I'd like to remove the
`show_cursor` functionality entirely as part of the effort to simplify
`explore`.
The style for selected cells is still configurable. I went with light
blue for the default background colour, it looks OK to me.

As a nushell user I could not find a way to implement custom completion

# Description
because we already have `null` as the value of the type `nothing` and as
a followup to the two other attempts of mine, i propose to remove the
redundant `$nothing` built-in variable 😋
this PR is the first step, deprecating `$nothing`.
a followup PR will remove it altogether and wait for 0.87 👍⚙️ **details**: a new `NOTHING_VARIABLE_ID = 3` has been added,
parsing `$nothing` will create it, finally a `Value::Nothing` will be
produced and a warning will be reported.
this PR already fixes the `toolkit.nu` module so that it does not throw
a bunch of warnings each time 👌

Closes#5436
When I opened this issue more than a year ago, I mainly wanted the
following capacity: easily access the full env and have the hability to
update it when a new version of `nushell` comes out.
With this PR I can now do the following:
```nu
source-env ~/.config/nushell/defaults/env.nu
source ~/.config/nushell/defaults/config.nu
# Update nushell default config & env file (run this after a version update)
def update-defaults [] {
config env --default | save -f ~/.config/nushell/defaults/env.nu
config nu --default | save -f ~/.config/nushell/defaults/config.nu
}
```
Which is more than enough for me. Along with `nushell` respecting the
XDG spec on macOS (`dirs-next` should be banned for CLI tools on macOS),
this should be one of the last hurdle before fully switching for me!

### Update winget submission workflow include only default msi files:

The new release workflow after
https://github.com/nushell/nushell/pull/10457 will add full featured
packages like: `nu-*-x86_64-windows-msvc-full.msi` and
`nu-*-aarch64-windows-msvc-full.msi` (A release preview could be found
here: https://github.com/nushell/nightly/releases/tag/nightly-6a2fd91 )
and this change will make sure only the default packages will be
included just the same as before to make sure that nothing will be
broken.
BTW: Due to lots of changes made recently about the release workflow, I
will stand-by for the next release.

Fix type checking in arguments default values not adhering to subtyping
rules
Currently following examples produce a parse error:
```nu
def test [ --qwe: record<a: int> = {a: 1 b: 1} ] { }
def test [ --qwe: list<any> = [ 1 2 3 ] ] { }
```
despite types matching. Type equality check is replaced with subtyping
check and everything parses fine:
# User-Facing Changes
Default values of flag arguments type checking behavior is in line with
`let` statements
# Description
This PR fixes#9702 on the side of parse. I.e. input/output types in
signature and type annotations in `let` now should correctly parse with
type annotations that contain commas and spaces:

@KAAtheWiseGit, I'm sorry, I didn't mean to block your first PR #10461,
didn't see you had submitted it till I got around to submitting this. If
you want to incoporate useful ideas from this PR into yours, I do not
mind deferring to you.
# Description
Changes made in `datetime-diff`:
* Initialize millisecond and microsecond fields in `$current`, to fix
the error when borrow needs to refer to them.
* Fix `borrow_nanoseconds` to borrow from seconds, not from (unused)
microseconds.
* Added error check to insist that first argument is >= second argument.
`datetime-diff` doesn't represent negative durations correctly (it tries
to borrow out of the year, resulting in negative year and positive all
other fields). We don't currently have a use case requiring negative
durations.
* Add comments so help is a bit clearer (I was surprised that the first
argument, named `$from` was actually supposed to be the *later*
datetime. The order of arguments is reasonable (reminiscent of <later>
<minus> <earlier>), so I just changed the param name to match its
purpose.
Changes made in `pretty-print-duration`:
* changed type of argument from `duration` to `record`. (it's not clear
why Nu was not complaining about this!)
* changed test for skipping a clause from `> 0` to `!= 0`. Even though
`datetime-diff` won't present a negative field in the record, user might
call `pretty-print-duration` with one, might as well handle it. (but I
think `hour:-2` will be rendered as `-2hr`, not `-2hrs`...).
* added help and an example.

# Description
Fixes: #10450
This pr differentiating between `--x: bool` and `--x`
Here are examples which demostrate difference between them:
```nushell
def a [--x: bool] { $x };
a --x # not allowed, you need to parse a value to the flag.
a # it's allowed, and the value of `$x` is false, which behaves the same to `def a [--x] { $x }; a`
```
For boolean flag with default value, it works a little bit different to
#10450 mentioned:
```nushell
def foo [--option: bool = false] { $option }
foo # output false
foo --option # not allowed, you need to parse a value to the flag.
foo --option true # output true
```
# User-Facing Changes
After the pr, the following code is not allowed:
```nushell
def a [--x: bool] { $x }; a --x
```
Instead, you have to pass a value to flag `--x` like `a --x false`. But
bare flag works in the same way as before.
## Update: one more breaking change to help on #7260
```
def foo [--option: bool] { $option == null }
foo
```
After the pr, if we don't use a boolean flag, the value will be `null`
instead of `true`. Because here `--option: bool` is treated as a flag
rather than a switch

## Description
This PR uses environment variables to enable and set a transient prompt,
which lets you draw a different prompt once you've entered a command and
you've moved on to the next line. This is useful if you have a fancy
two-line prompt with a bunch of info about time and git status that you
don't really need in your scrollback buffer.
Here's a screenshot. You can see how my usual prompt has two lines and
would take up a lot more space if every past command also used the full
prompt, but reducing past prompts to `🚀` or `>` makes it take up less
space.
I added the following lines to my `env.nu` to get that rocket as the
prompt initially:
```nu
$env.TRANSIENT_PROMPT_COMMAND = {|| "" }
$env.TRANSIENT_PROMPT_INDICATOR = {|| open --raw "~/.prompt-indicator" }
$env.TRANSIENT_PROMPT_INDICATOR_VI_INSERT = $env.TRANSIENT_PROMPT_INDICATOR
```
## User-Facing Changes
If you want to change a segment of the prompt, set the corresponding
`TRANSIENT_PROMPT_*` variable.
<!-- If your PR had any user-facing changes, update [the

-->
## Problems/Things to Consider:
- The transient prompt clones the `Stack` at the very beginning of the
session and keeps that around. I'm not sure if that could cause
problems, but if so, it could probably take an `Arc<State>` instead.
- This isn't truly a problem, but now there's even more environment
variables, which is kinda annoying.
- There might be some performance issues with creating a new
`NushellPrompt` object and cloning the `Stack` for every segment of the
transient prompt. What's more, the transient prompt is added to the
`Reedline` object whether or not the user has enabled transient prompt,
so if there are indeed performance issues, simply disabling the
transient prompt won't help.
- Perhaps instead of a separate `TRANSIENT_PROMPT_INDICATOR_VI_INSERT`
and `TRANSIENT_PROMPT_INDICATOR_VI_NORMAL`, `TRANSIENT_PROMPT_INDICATOR`
could be used for both (if it exists). Insert and normal mode don't
really matter for previously entered commands.

When parse_range get an item like ((((1..2)))) it would try to parse
"((((1" with a long chain of recursive parsers, namely:
- parse_value
- parse_paren_expr
- parse_full_cell_path
- parse_block
- parse_pipeline
- parse_builtin_commands
- parse_expression
- parse_math_expression
- parse_value
- ...
where `parse_paren_expr` calls `parse_range` in turn. Because at any
time in the chain `parse_paren_expr` can call `parse_range`, which will
then continue the chain, we get quadratic number of function calls, each
linear on the size of the input
By checking with the lexer that the parens are matched, we prevent the
long chain from being called on unmatched braces. Now, this is still
more quadratic than it needs to be, to fix that, we should process
parens only once, instead of on each recursive call

Found using the fuzzer, by setting a timeout on max run-time. It also
found a stack-overflow on too many parentheses, which this doesn't fix.
# Description
This PR fixes a bug found by @kubouch where `$nu` is not evaluated as a

# Description
While reviewing #10350 I noticed that a `HashSet<usize>` was used to
deduplicate the incoming rows, which are then sorted after cloning to a
separate `Vec`. This sounds like a candidate for a `BTreeSet` which
guarantees the ordering.
In the process I removed some dead code.
- Use `BTreeSet` instead of `HashSet`
- Remove dead `skip` logic
- Use `BTreeSet` directly in `NthIterator`
- Consume `BTreeSet` through `Peekable<IntoIter>`
Factor the big parts into separate files:
- `state_delta.rs`
- `state_working_set.rs`
- smaller `usage.rs`
This required adjusting the visibility of several parts.
Makes `StateDelta` transparent for the module.
Trying to reduce visibility in some other places

# Description
Unify the logic between `nu!` and `nu_with_std!`.
The inner code actually does not contain any variadic components. So it
can safely be abstracted into a function.
Similarly simplify the variadic to an array in `nu_with_plugin!`
This also seems to simplify the codegen for tests.

```sh

# Description
This new command `into value` is a command that tries to infer the type
of data you have in a table. It converts each cell to a string and then
runs a set of regular expressions on that string. This was mostly
cobbled together after looking at how polars does similar things. The
regular expressions were taken straight form polars and tweaked.

It's definitely not perfect. There are ways it will fail because on
regular expressions not working on all formats. My hope is that people
will pick this up and add more regular expressions and if there are
problems with the existing ones, change them. This is meant as a
"starter command" with easy entry for newcomers that are looking to chip
in and help out.
Also, some tests probably need to be added to ensure what we have now
doesn't break with updates.

# Description
Fixes: #10410
So the following script is possible:
```nushell
def a [b: any = null] { let b = ($b | default "default_b"); }
a "given_b"
```
## About the change
When parsing signature, and nushell meets something like `a: any`, it
force the parser to treat `a` as `any` type. This is what
`arg_explicit_type` means, it's only set when we goes into
`ParseMode::TypeMode`, and it will be reset to `false` if the token goes
to next argument.
so, when we have something like this: `def a [b: any = null] { $b }`,
the type of `$b` won't be overwritten.
But if we have something like this: `def a [b = null] { $b }`, the type
of `$b` is not annotated, so we make it to be `nothing`(which is the
type of null)

Before this change, parsing `[[[[[[[[[[[[[[[[[[[[[[` would cause nushell
to consume several gigabytes of memory, now it should be linear in time.
The old code first tried parsing the head of the table as a list and
then after that it checked if it got more arguments. If it didn't, it
throws away the previous result and tries to parse the whole thing as a
list, which means we call `parse_list_expression` twice for each call to
`parse_table_expression`, resulting in the exponential growth
The fix is to simply check that we have all the arguments we need before
parsing the head of the table, so we know that we will either call
parse_list_expression only on sub-expressions or on the whole thing,
never both.
Fixes#10438

# Description
We made the decision that our floating point type should be referred to
as `float` over `decimal`.
Commands were updated by #9979 and #10320
Now make the internal codebase consistent in referring to this data type
as `float`.
Work for #10332
# User-Facing Changes
`decimal` has been removed as a type name/symbol.
Instead of
```nushell
def foo [bar: decimal] decimal -> decimal {}
```
use
```nushell
def foo [bar: float] float -> float {}
```
Potential effect of `SyntaxShape`'s `Display` implementation now also
referring to `float` instead of `decimal`
# Details
- Rename `SyntaxShape::Decimal` to `Float`
- Update `Display for SyntaxShape` to `float`
- Update error message + fn name in dataframe code
- Fix docs in command examples
- Rename tests that are float specific
- Update doccomment on `SyntaxShape`
- Update comment in script
# Tests + Formatting
Updates the names of some tests
# Description
This PR adds a helper flag named `--cursor-end`/`-e` that allows you to
set the cursor to the end of the buffer. Before this, you'd have to do
something like `--cursor 100` where you're guessing that 100 would be
longer than the buffer and just put it at the end.

# Description
By using a `from: 1` the additional subexpression for `to` becomes
unnecessary.

note: test are not actually make scenes cause `nu!` strips colors.
(Ideally it would need a flag to not do so)
note: It does does does ... slower down quite a bit rendering... (
PS: Maybe it's better being a flag to `table` rather then a
configuration option?
PS: I am not sure why the logic was removed in a first place
This PR is in reference to #10215.
This PR changes `select` to work even if multiple equal items were
provided.
This would previously error, but now works
```nushell
let arg = [ 1 a ]
[[a b c]; [1 2 3] [4 5 6] [7 8 9]]
| select $arg
```
# User-Facing Changes
Nothing too radical, just experience improvements. Users won't need to
pass the values through `unique` beforehand.
# Description
Currently we support "multiplication" of strings, resulting in a terse
way to repeat a particular string.
This can have unintended side effects when dealing with mixed data (e.g.
after parsing data that is not all numbers).
Furthermore as we frequently fall-back to strings while parsing source
code, this introduced a runaway edge case in const evaluation (#10212)
Work for #10233
## Details
- Remove python-like string multiplication.
- Workaround for indentation
- This should probably be addressed with a purpose built command
- Remove special const-eval error test
# User-Facing Changes
**Major breaking change!**
`"string" * 42` will stop working. (This was used for example in the
stdlib)
We should bless a good alternative before landing this
---------
Co-authored-by: JT <547158+jntrnr@users.noreply.github.com>
Elide the reference for `Copy` type (`usize`)
Use the canonical deref where possible.
* `&Box` -> `&`
* `&String` -> `&str`
* `&PathBuf` -> `&Path`
Skips the ctrl-C handler for now.
# Description
The pythonism that multiplying a scalar integer with a list results in a
repeated concatenation of the list, is ambiguous with other possible
interpretations and thus actively harmful to clear semantics in nushell.
Another possible reading of this scalar/vector product would be trying
to perform elementwise multiplication with the scalar.
Before we bless this alternative as a more reasonable design the best
course of action is to remove this pythonism.
Work related to #10233
# User-Facing Changes
Breaking change as this turns `int * list` or `list * int` into hard
errors.
# Tests + Formatting
Remove the associated test

# Description
this PR adds a `repeat` command to the standard library
# User-Facing Changes
a new `repeat` command in `std`
```nushell
repeat anything a bunch of times, yielding a list of *n* times the input
# Examples
repeat a string
> "foo" | std repeat 3 | str join
"foofoofoo"
Usage:
> repeat <n>
Flags:
-h, --help - Display the help message for this command
Parameters:
n <int>: the number of repetitions, must be positive
Input/output types:
╭───┬───────┬───────────╮
│ # │ input │ output │
├───┼───────┼───────────┤
│ 0 │ any │ list<any> │
╰───┴───────┴───────────╯
```
# Tests + Formatting
a new test called `repeat_things` in `test_std.nu`
# After Submitting
# Description
This PR tried to add a few more columns to the Linux `ps -l` command.
Those columns are:
* start_time
* user_id
* priority
* process_threads
There are a few that I left commented out that could be added but the
screen was beginning to look crowded. So, I left out:
* group_id
* session_id
* tgp_id (which could be helpful for eventual job control)
And there's like 100 more things that could be added that didn't seem
especially useful right now.

# Description
This changes `echo` to work more closely to what users of other shells
would expect:
* when redirected, `echo` works as before and sends values through the
pipeline
* when not redirected, `echo` will print values to the screen/terminal
# User-Facing Changes
A standalone `echo` now will print to the terminal, if not redirected.
The `echo` command is no longer const eval-able, as it will now print to
the terminal in some cases.

fixes#8551
# Description
Use `open::commands` function to get list of command available for
starting given path. run commands directly, providing environment, until
one of them is successful.
example of output if start was not successful:
```
~\code\nushell> start ..\nustart\a.myext 09/12/2023 01:37:55 PM
Error: nu:🐚:external_command
× External command failed
╭─[entry #1:1:1]
1 │ start ..\nustart\a.myext
· ─────────┬────────
· ╰── No command found to start with this path
╰────
help: Try different path or install appropriate command
Command `cmd /c start "" "..\nustart\a.myext"` failed with exit code: 1
```
# User-Facing Changes
`start` command now provides environment to the external command. This
is how it worked in `nu 0.72`, see linked issue.
# Tests + Formatting
`start` command didn't have any tests and this PR does not add any.
Integration-level tests will require setup specific to OS and
potentially change global environment on testing machine. For unit-level
test it is possible to test `try_commands` function. But is still runs
external commands, and robust test will require apriori knowledge which
commands are necessary successful to run and which are not.
# Description
Similar to #9979
# User-Facing Changes
`random decimal` will now raise a warning and can be removed in an
upcoming release.
New command is named `random float`
# Tests + Formatting
Tests updated and improved.
# Description
We keep "into decimal" for a release and warn through a message that it
will be removed in 0.86.
All tests are updated to use `into float`
# User-Facing Changes
`into decimal` raises a deprecation warning, will be removed soon.

# Description
This generally makes for nicer APIs, as you are not forced to use an
existing allocation covering the full `String`.
Some exceptions remain where the underlying type requirements favor it.
# User-Facing Changes
None
# Description
This removes pipeline element profiling. This could be a useful feature,
but pipeline elements are going to be the most sensitive to in terms of
performance, as `eval_block` and how pipelines are built is one of the
hot loops inside of the eval engine.
# User-Facing Changes
Removes pipeline element profiling.

# Description
This PR adds new flag `--keep-order/-k` for the `par_each` filter. This
flag keeps sequence of output same as the order of input.
Output without the flag:
```nu
> 1..6 | par-each {|n| $n * 2 }
╭────╮
│ 4 │
│ 10 │
│ 2 │
│ 8 │
│ 12 │
│ 6 │
╰────╯
```
Output with the `--keep-order` flag:
```nu
> 1..6 | par-each --keep-order {|n| $n * 2 }
╭────╮
│ 2 │
│ 4 │
│ 6 │
│ 8 │
│ 10 │
│ 12 │
╰────╯
```
I think the presence of this flag is justified, since:
- Much easier to use than `.. | enumerate | par-each {|p| update item
..} | sort-by index | get item`
- Faster, as it uses internally parallel sorting in the same thread pool
A note about naming: it may conflict with `--keep-empty/-k` flag of the
`each` filter if the same feature will be used in `par-each`, so maybe
it needs some other name.

# Description
Fixes#10300 , where using variables didnt work with `ucp` as it was
only expecting a `Expr::FilePath`.
Before: (from the issue)
```
❯ ucp -r $var $folder
Error: × Missing file operand
╭─[entry #40:1:1]
1 │ ucp -r $var $folder
· ─┬─
· ╰── Missing file operand
╰────
help: Please provide source and destination paths
```
Now:
```
`ucp -r $var $folder`
# success
```
Also added the test to ensure its working:) . Oh, and I tweaked again
slightly the messages on two tests because now the whole `path` is
printed rather than `a`. Say:
```
#before
`cp a a` --> 'a' and 'a' are the same file
# now
`cp a a` --> /home/current/location/a and /home/current/location/a are the same file
```

two cool things about the `where` command
- it's versatile enough to allow creating a case-insensitive version of
itself
- it does not require the explicit use of a closure

case-insensitively and without an explicite closure.
# User-Facing Changes

This PR is in relation to #10215
# Description
This PR introduces `reject` to receive list of columns or rows as
argument.
This change is similar to change of `select` and the code used is
similar.
# User-Facing Changes
The user will be able to pass a list as rejection arguments.
```nushell
let arg = [ type size ]
[[name type size]; [ cargo.toml file 20mb ] [ Cargo.lock file 20mb] [src dir 100mb]] | reject $arg
```
# Description
This PR fixes `reject` failing when providing row items in ascending
order.
# User-Facing Changes
users can now `reject` multiple rows independently of each other.
```nushell
let foo = [[a b]; [ 1 2] [3 4] [ 5 6]]
# this will work independant of the order
print ($foo | reject 2 1)
print ($foo | reject 1 2)
```

# Description
There are several cursor shape related issues #7151#9243#7271#8452#10169, you can't disable the cursor shape feature even if you comment
out the entire `cursor_shape` block in the config.nu, and even worse,
when nushell exits with an error, the cursor shape can't be restored,
that is annoying.
This PR provides an opportunity to disable setting the cursor shape.
# User-Facing Changes
If you use the default config.nu, nothing changes, but if you comment
out `cursor_shape` block or set them to `inherit`, related cursor shape
will not be set.

Supercedes https://github.com/nushell/nushell/pull/10196
# Description
After reading
https://github.com/nushell/nushell/pull/10196#issuecomment-1703986359 I
added a signpost from `keybindings listen` to `input listen`
When I initially tried `input listen` it always immediately returned
with:
```
╭───────┬────────╮
│ type │ focus │
│ event │ gained │
╰───────┴────────╯
```
I added an example to `input listen --help` to suggest only listening to
key events
Initially I also included a `result` but it prints as:
```
╭───────────┬───────────────╮
│ type │ key │
│ key_type │ char │
│ code │ c │
│ modifiers │ [list 1 item] │
╰───────────┴───────────────╯
```
rather than:
```
╭───────────┬───────────────────────────────╮
│ type │ key │
│ key_type │ char │
│ code │ c │
│ │ ╭───┬───────────────────────╮ │
│ modifiers │ │ 0 │ keymodifiers(control) │ │
│ │ ╰───┴───────────────────────╯ │
╰───────────┴───────────────────────────────╯
```
so I removed it.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
* Example describing how to use `input list --types [key]` to listen for
keybindings.
* Signpost pointing at `use std input; input list --types [key]` from
`keybindings list`.
## After merging
It is probably worth:
a) signposting to the keybindings section of the book from both of these
subcommands (like I did in
https://github.com/nushell/nushell/pull/10193),
b) giving an example in the book of how to take the output from `input
listen --types [key]` and format it for including in `config nu`
c) there are not currently any examples in
crates/nu-utils/src/sample_config/default_config.nu for keybindings with
multiple modifiers. Should I add alt+backspace-in-macos-vscode as an
example (gets translated to `{ modifier: control_alt keycode: char_h }`
for historical reasons)?

# Description
Hi. Basically, this is a continuation of the work that @fdncred started.
Given some nice discussions on #9463 , and [merged uutils
PR](https://github.com/uutils/coreutils/pull/5152) from @tertsdiepraam
we have decided to give the `cp` command the `crawl` stage as it was
named.
> [!NOTE]
Given that the `uutils` crate has not made the release for the merged
PR, just make sure you checkout latest and put it in the required place
to make this PR work.
The aim of this PR is for is to see how to move forward using `uutils`
crate. In order to getting this started, I have made the current
`nushell cp tests` pass along with some extra ones I copied over from
the `uutils` repo.
With all of that being said, things that would be nice to decide, and
keep working on:
Crawl:
- Handling of certain `named` flags, with their long and short
forms(e.g. --update, --reflink, --preserve, etc), and using default
values. Maybe `-u` can already have a `default_missing_value`.
- Should we maybe just support one single option `switch` flags (see
`--backup` in code) as a contrast to the other named args.
- Complete test coverage from `uutils`. They had > 100 tests, and I
could only port like 12 as they are a bit time consuming given they
cannot be straight up copy pasted. Maybe we do not need all >100, but
maybe the more relevant to what we want.
- Refactor this code
Walk:
- Non fatal errors on `copy` from `utils`. Currently it just sends it to
stdout but errors have no span
- Better integration
An added possibility is the addition of `SyntaxShape::OneOf()` for
`Named` arguments which was briefly mentioned in the discord server, but
that is still to be decided. This could greatly improve some of the
integration. This would enable something like `cp --preserve [all
timestamp]` or `cp --preserve all` to both work.
I did not want to keep holding on this, and wait till I was happy with
the code because I think its nice if everyone can start up and suggest
refactors, but the main important part now was getting it out the door,
as if I take my sweet time this will take way longer 😛

# Description
When launching nushell interactively from another shell, the parent
shell usually gives us own our process group and handles restoring
control to itself. However, other programs that do not support job
control expect us to give control of the terminal back to them. This PR
makes it so that we record the initial foreground process group and
restore it when nushell exits. An "exit" can be from the `exit` command,
a panic, or a `SIGTERM` signal.
The changes in `terminal.rs` mostly follow [fish's
example](0874dd6a96/fish-rust/src/common.rs (L1634)).
# User-Facing Changes
Fixes interactions between nushell and other interactive CLI commands
(e.g., VIFM #10015).
This PR removes the `explore.try.border_color` config item, and instead
always uses the `separator` colour (the one used for regular table
borders) from the current theme.
The PR also removes some unused `explore.config` bits from the default
config (I missed this in https://github.com/nushell/nushell/pull/10259).
### Future Work
This PR is intentionally small, I want to confirm that I'm on the right
track before I rip out more colour config from `explore`. If all goes
well, expect more PRs like this soon.
### Testing
I confirmed that this works by changing my `separator` colour in
`config.nu`, and also confirmed that nothing breaks if a user still has
`explore.try.border_color` in their config.
# Description
Apparently some strftime formats are already localized and when you
"double localize" them, they don't work. This PR fixes that so that %x
%X %r %c don't go through the localization step.
Example: %x %X
### Before
```nushell
❯ date now | format date "%x %X %p"
09/08/2023 08 AM
```
### After
```nushell
❯ date now | format date "%x %X %p"
09/08/23 08:09:14 AM
```
I started to make one format_datetime to rule them all but one returns a
string and one returns a value. If we convert to the string, we lose the
nice error messages. If we change to value, more code has to be changed
elsewhere. So, I decided to just leave two functions.

Currently, `ctrl+z` is the command to exit `explore` no matter where you
are in the UI. IMO this is a bit unintuitive since that's usually used
to suspend a process.
After this change, `ctrl+c`, `ctrl+d`, and `ctrl+q` all work to exit
`explore`.
I think these are all shortcuts that users might try when attempting to
exit `explore`, and I think we might as well handle them all.
More trimming of underused `explore` functionality.
The `explore` command has subcommands that can be run like `:config` or
`:try` or whatnot. This PR removes the `:config`, `:show-config`, and
`:tweak` commands which are all for viewing+modifying config.
These are interesting commands and they were cool experiments, but
ultimately I don't think they fit with our plans for a simplified
`explore`. They'd need a lot more polish if we want to keep them and I
don't think we do. Happy to discuss if I've missed a good reason to keep
these.
cc @fdncred
Removing 2 underused config options from `explore`.
`show_banner` controls whether `For help type :help"` is shown in the
message area when `explore is first launched. I don't think there's any
good reason not to show it, it's not a modal dialog or anything.
`exit_esc` controls whether to exit `explore` when `esc` is pressed and
we can't "go up" any further (or at least that's what it's supposed to
do, looking at the code I'm not so sure). IMO we don't need to make this
kind of basic interaction configurable unless there's a really good
reason.
## Context
`explore` is complicated and we want to overhaul its design. It will be
easier to make meaningful changes if `explore` is a little slimmer
first, so I'm trying to pare back unused/underused code and config as a
starting point.
I'm gonna be making more PRs like this, I'll try to keep them
small+self-contained.
Add Dorothy — https://github.com/bevry/dorothy — to the supported by
section. Dorothy is a dotfile ecosystem that enables a cross-shell and
cross-operating system dotfile experience. Allowing you to easily switch
to Nu, while keeping your existing env configuration, and allowing you
to write Nu commands that are accessible to other shells.
Dorothy now has CI testing for its Nu integration.
# Description
This PR reverts some changes to NU_LIB_DIRS and NU_PLUGIN_DIRS in the
default_env.config file. Our practice is to have default configs that
match if you were to run `nu -n`. I agree with this goal, but until
someone adds NU_LIB_DIRS and NU_PLUGIN_DIRS, we should revert this
change and not penalize users, breaking their scripts that run with `nu
-c blah` when `blah` is located in the default_env's NU_LIB_DIRS.

# Description
This PR allows the `--login`/`-l` parameter to be used with nushell's
`--commands`/`-c` parameter. When you do this, since you're invoking it
with the `-l` flag, nushell will load your env.nu, config.nu, and
login.nu, in that order. Then it will proceed to run your commands. I
think this provides a better quality of life when you want to run
scripts with your personal config files as a login shell.

# Description
before this PR,
```nushell
> $.a.b | describe
cell path
```
which feels inconsistent with the `cell-path` type annotation, like in
```nushell
> def foo [x: cell-path] { $x | describe }; foo $.a.b
cell path
```
this PR changes the name of the "cell path" type from `cell path` to
`cell-path`
# User-Facing Changes
`cell path` is now `cell-path` in the output of `describe`.
this might be a breaking change in some scripts.
same goes with
- `list stream` -> `list-stream`
- `match pattern` -> `match-pattern`
# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- ⚫ `toolkit test`
- ⚫ `toolkit test stdlib`
this PR adds a new `cell_path_type` test to make sure it stays equal to
`cell-path` in the future.

As soon as this information is documented people are much more likely to

sparks joy or not.
this closes#10248
@fdncred pointed out the problem and he was correct 😄
I went ahead and made the simple change and the
https://github.com/influxdata/influxdb_iox binary
works like a charm...
@amtoine hopefully there are no issues with this change
I believe its a good one as other rust binaries might take advantage of
this common
environment variable as well...
should close https://github.com/nushell/nushell/issues/10237

I think this is `sleep`'s specific issue, it's because it always return
a `Value::nothing` where it's interrupted by `ctrl-c`.
To fix the issue, I'd propose to make it returns Err(ShellError)
This is how it behaves:
```nushell
❯ sleep 5sec; echo "hello!"
^CError: nu:🐚:sleep_breaked
× Sleep is breaked.
❯ sleep 5sec; ^echo "hello!"

# Description
Currently on Android, there are warnings about unused variables. This PR
fixes that with more conditional guards for the unused variables.
Additionally, in #10013, @kubouch gave feedback in [the last
PR](https://github.com/nushell/nushell/pull/10013#pullrequestreview-1596828128)
that it was unwieldy to repeat
```rust
#[cfg(all(
feature = "trash-support",
not(target_os = "android"),
not(target_os = "ios")
))]
```
# Description
* The path to the binaries for tests is slightly incorrect. It is
missing the build target when it is set with the `CARGO_BUILD_TARGET`
environment variable. For example, when `CARGO_BUILD_TARGET` is set to
`aarch64-linux-android`, the path to the `nu` binary is:
`./target/aarch64-linux-android/debug/nu`
rather than
`./target/debug/nu`
This is common on Termux since the default target that rustc detects can
cause problems on some projects, such as [python's `cryptography`
package](https://github.com/pyca/cryptography/issues/7248).
This technically isn't a problem specific to Android, but is more likely
to happen on Android due to the latter.
* Additionally, the existing variable named `NUSHELL_CARGO_TARGET` is in
fact the profile, not the build target, so this was renamed to
`NUSHELL_CARGO_PROFILE`. This change is included because without the
rename, the build system would be using `CARGO_BUILD_TARGET` for the
build target and `NUSHELL_CARGO_TARGET` for the build profile, which is
confusing.
* `std path add` tests were missing `android` test
# User-Facing Changes
For those who would like to build nushell on Termux, the unit tests will
pass now.
# Description
This PR makes `append`/`prepend` more consistent, in particular, it allows you to
work with ranges. Previously, you couldn't append a list by range:
```nu
> 0..1 | append 2..4
╭──────╮
│ 0 │
│ 1 │
│ 2..4 │
╰──────╯
```
Now it works:
```nu
> 0..1 | append 2..4
╭───╮
│ 0 │
│ 1 │
│ 2 │
│ 3 │
│ 4 │
╰───╯
```
# User-Facing Changes
If someone needs the old behavior, then it can be obtained like this:
```nu
> 0..1 | append [2..4]
╭──────╮
│ 0 │
│ 1 │
│ 2..4 │
╰──────╯
```
the example for `history` was out of date, this PR updates it.

Fix https://github.com/nushell/nushell/issues/10136
# Description
Current nushell only handle path containing '*' as match pattern and
treat '?' as just normal path.
This pr makes path containing '?' is also processed as pattern.
🔴 **Concerns: Need to design/comfirm a consistent rule to handle
dirs/files with '?' in their names.**
Currently:
- if no dir has exactly same name with pattern, it will print the list
of matched directories
- if pattern exactly matches an empty dir's name, it will just print the
empty dir's content ( i.e. `[]`)
- if pattern exactly matches an dir's name, it will perform pattern
match and print all the dir contains
e.g.
```bash
mkdir src
ls s?c
```
| name | type | size | modified |
| ---- | ---- | ------ | --------------------------------------------- |
| src | dir | 1.1 KB | Tue, 29 Aug 2023 07:39:41 +0900 (9 hours ago) |

# Description
This updates most crates to 0.27 `crossterm`.
To do so we need the most recent `ratatui`
`reedline` can now update as well.
See https://github.com/nushell/reedline/pull/625
Sadly this introduces some crate duplication again as there are some
other dependency updates.
Furthermore we have another crate depending on 0.26.1 crossterm
(`comfy-table` that some how gets pulled in by polars)

# Description
i have been annoyed enough by this missing feature, so let's add that to
Nushell without requiring any user configuration 😏
# User-Facing Changes
this PR should allow tab completion cycling everytime, without requiring
the user to use the default config files or add the following
keybindings to their config
```nushell
{
name: completion_menu
modifier: none
keycode: tab
mode: [emacs vi_normal vi_insert]
event: {
until: [
{ send: menu name: completion_menu }
{ send: menunext }
{ edit: complete }
]
}
}
```
### 🧪 try it out
from the root of the repo, one can try `<tab>` in each of the following
cases:
- `cargo run -- -n` to load Nushell without any config
- `cargo run -- --config
crates/nu-utils/src/sample_config/default_config.nu --env-config
crates/nu-utils/src/sample_config/default_env.nu` to load the default
configuration
- `cargo run` to load the user configuration
## before
- `<tab>`, `ls <tab>` and `str <tab>` only work with the second `cargo
run`, i.e. when loading the default config files
## after
- `<tab>` should cycle through the available commands
- `ls <tab>` should cycle through the available files and directories
- `str <tab>` should cycle the subcommands of `str`
in all three cases

# Description
This PR adds the ability to have a `$nu.plugin-path` even when you
plugins are registered and it also should work with `nu -n --no-stdlib`.
### Before
It would give an error
```
│ plugin-path │ IOError("Could not get plugin signature location") │
```
### After
It returns the proper path, like this for me
```
│ plugin-path │ /Users/fdncred/Library/Application Support/nushell/plugin.nu │
```

close#8074
I attempted to refactor the "input" command. The reason for this is that
the current implementation of the "input" command lacks consistency for
different options. For instance, some parts use `std::io::stdin` while
others use `crossterm::event::read`.
In this pull request, I have made changes to use crossterm consistently:
- Detection of the -u option is now done using `crossterm`'s
`KeyCode::Char`.
- The current input is displayed when using `crossterm` for input (it
won't be displayed when -s is present).
- Ctrl-C triggers SIGINT.
# User-Facing Changes
Users can interrupt "input" with ctrl-c.
# Description
Changed the default env file so that home is found using `$nu.home-path`
instead to using an if-else statement to find the os then find the
specific environment variable
They relied on the `nu_plugin_inc` but where behind a feature flag that
isn't actually defined anywhere. These tests of `update` or `upsert`
shouldn't really depend on `inc` so I decided to remove them outright as
they haven't been used to exercise the commands under test.
As described in Issue #8670, removed `pipeline()` wherever its argument
contained no line breaks.

- fixes https://github.com/nushell/nushell/issues/5559
# Description
Current `lite_parse` does not handle multiple line comments and eols in
pipeline.
When parsing the following tokens:
| `"abcdefg"` | ` \|` | `# foobar` | ` \n` | `split chars` |
| ------------- | ------------- |------------- |-------------
|------------- |
| [Command] | [Pipe] | [Comment] | [Eol] | [Command] |
| | | Last Token |Current Token | |
`TokenContent::Eol` handler only checks if `last_token` is `Pipe` but it
will be broken if there exist any other thing, e.g. extra `[Comment]` in
this example.
This pr make the following change:
- While parsing `[Eol]`, try to find the last non-comment token as
`last_token`
- Comment is supposed as `[Comment]+` or `([Comment] [Eol])+`
- `[Eol]+` is still parsed just like current nu (i.e. generates
`nothing`).
Notice that this pr is just a quick patch if more comment/eol related
issue occures, `lite_parser` may need a rewrite.
# User-Facing Changes
Now the following pipeline works:
```bash
1 | # comment
each { |it| $it + 2 } | # comment
math sum
```
Comment will not end the pipeline in interactive mode:
```bash

▶▶ # foo
▶▶ 2

other developers to continue to use hook even if they decide to write
their on cli or NOT depend on nu-cli
Then they will still have the hook functionality because they can
include nu-cmd-base
- fixes#10083
# Description
nushell crashes in the following 2 condition:
- `let a = {}` , then delete `{`
- `let a = | {}`, then delete `{`
When delete `{` the pipeline becomes empty but current `nu-parser`
assume they are non-empty. This pr adds extra empty check to avoid
crash.

# Description
This PR names the hooks as they're executing so that you can see them
with debug statements. So, at the beginning of `eval_hook()` you could
put a dbg! or eprintln! to see what hook was executing. It also shows up
in View files.
### Before - notice item 14 and 25
### After - The hooks are now named (14 & 25)
Curiosity, on my mac, the display_output hook fires 3 times before
anything else. Also, curious is that the value if the display_output, is
not what I have in my config but what is in the default_config. So,
there may be a bug or some shenanigans going on somewhere with hooks.

# Description
This PR adds a new config item, `error_style`. It will render errors in
a screen reader friendly mode when set to `"simple"`. This is done using
`miette`'s own `NarratableReportHandler`, which seamlessly replaces the
default one when needed.
Before:
```
Error: nu:🐚:external_command
× External command failed
╭─[entry #2:1:1]
1 │ doesnt exist
· ───┬──
· ╰── executable was not found
╰────
help: No such file or directory (os error 2)
```
After:
```
Error: External command failed
Diagnostic severity: error
Begin snippet for entry #4 starting at line 1, column 1
snippet line 1: doesnt exist
label at line 1, columns 1 to 6: executable was not found
diagnostic help: No such file or directory (os error 2)
diagnostic code: nu:🐚:external_command
```
## Things to be determined
- ~Review naming. `errors.style` is not _that_ consistent with the rest
of the code. Menus use a `style` record, but table rendering mode is set
via `mode`.~ As it's a single config, we're using `error_style` for now.
- Should this kind of setting be toggable with one single parameter?
`accessibility.no_decorations` or similar, which would adjust the style
of both errors and tables accordingly.
# User-Facing Changes
No changes by default, errors will be rendered differently if
`error_style` is set to `simple`.

# Description
this PR does not quite address

implement configurable keybindings for `explore` but rather only adds
support for Vim-like motions *out of the box*.
# User-Facing Changes
in *view* and *cursor* modes,
- `h`, `j`, `k` and `l` give standard Qwerty-based Vim motions
- `g` and `G` go to the top and the end respectively
- `u` and `d` scroll up and down
> **Note**
> the bindings do not support the use of modifiers for now, so it's not
`c-u` and `c-d` which scroll pages but rather `u` and `d`

# Description
This doesn't really do much that the user could see, but it helps get us
ready to do the steps of the refactor to split the span off of Value, so
that values can be spanless. This allows us to have top-level values
that can hold both a Value and a Span, without requiring that all values
have them.
We expect to see significant memory reduction by removing so many
unnecessary spans from values. For example, a table of 100,000 rows and
5 columns would have a savings of ~8megs in just spans that are almost
always duplicated.

# Description
This PR creates a new `Record` type to reduce duplicate code and
possibly bugs as well. (This is an edited version of #9648.)
- `Record` implements `FromIterator` and `IntoIterator` and so can be
iterated over or collected into. For example, this helps with
conversions to and from (hash)maps. (Also, no more
`cols.iter().zip(vals)`!)
- `Record` has a `push(col, val)` function to help insure that the
number of columns is equal to the number of values. I caught a few
potential bugs thanks to this (e.g. in the `ls` command).
- Finally, this PR also adds a `record!` macro that helps simplify
record creation. It is used like so:
```rust
record! {
"key1" => some_value,
"key2" => Value::string("text", span),
"key3" => Value::int(optional_int.unwrap_or(0), span),
"key4" => Value::bool(config.setting, span),
}
```
Since macros hinder formatting, etc., the right hand side values should
be relatively short and sweet like the examples above.
Where possible, prefer `record!` or `.collect()` on an iterator instead
of multiple `Record::push`s, since the first two automatically set the
record capacity and do less work overall.
# User-Facing Changes
Besides the changes in `nu-protocol` the only other breaking changes are
to `nu-table::{ExpandedTable::build_map, JustTable::kv_table}`.
Developer mode needs to be enabled to create symlinks on Windows. Since
creating symlinks is part of the testbench, this needs to be enabled.
(I always wondered why two tests fail on my Windows machine, but not on
the CI)

I had fixed the issue on Linux but not Windows. Context:
https://github.com/nushell/nushell/issues/9910#issuecomment-1689308886

`watch . {|a,b| print $a; print $b}` and confirming that it prints once
when I change a file in the current directory.
# Description
This PR removes `record` processing from the `length` command. It just
doesn't make sense to try and get the length of a record. This PR also
removes the `--column` parameter. If you want to list or count columns,
you could use `$table | columns` or `$table | columns | length`.

# Description
We allowed two default lints due to false positives. This should be
locally addressed with explicit information what causes either a false
positive or why a particular design choice in the code is made.
# User-Facing Changes
None
# Tests + Formatting
We should detect a few more things with clippy out of the box. If you
encounter a false positive you will need to address it on a case by case
basis.
If you have a `config` variable defined at some point after reading
config files, Nushell would print
```
warning: use `$env.config = ...` instead of `let config = ...`
```
I think it's long enough since we've used `$env.config` that we can
remove this. Furthermore, it should be printed during `let` parsing
because you can end up with a `config` constant after importing a
`config` module (that was my case). The warning thus can be misleading.

https://github.com/nushell/nushell/pull/9773 introduced constants to
modules and allowed to export them, but only within one level. This PR:
* allows recursive exporting of constants from all submodules
* fixes submodule imports in a list import pattern
* makes sure exported constants are actual constants
Should unblock https://github.com/nushell/nushell/pull/9678
### Example:
```nushell
module spam {
export module eggs {
export module bacon {
export const viking = 'eats'
}
}
}
use spam
print $spam.eggs.bacon.viking # prints 'eats'
use spam [eggs]
print $eggs.bacon.viking # prints 'eats'
use spam eggs bacon viking
print $viking # prints 'eats'
```
### Limitation 1:
Considering the above `spam` module, attempting to get `eggs bacon` from
`spam` module doesn't work directly:
```nushell
use spam [ eggs bacon ] # attempts to load `eggs`, then `bacon`
use spam [ "eggs bacon" ] # obviously wrong name for a constant, but doesn't work also for commands
```
Workaround (for example):
```nushell
use spam eggs
use eggs [ bacon ]
print $bacon.viking # prints 'eats'
```
I'm thinking I'll just leave it in, as you can easily work around this.
It is also a limitation of the import pattern in general, not just
constants.
### Limitation 2:
`overlay use` successfully imports the constants, but `overlay hide`
does not hide them, even though it seems to hide normal variables
successfully. This needs more investigation.

# Description
This PR tries to fix `into datetime`. The problem was that it didn't
support many input formats and the `--format` was clunky. `--format` is
still a bit clunky but can work. The big change here is that it first
tries to use `dtparse` to convert text into datetime.
### Before
```nushell
❯ '20220604' | into datetime
Thu, 01 Jan 1970 00:00:00 +0000 (53 years ago)
```
### After
```nushell
❯ '20220604' | into datetime
Sat, 04 Jun 2022 00:00:00 -0500 (a year ago)
```
## Supported Input Formats
`dtparse` should support all these formats. Taken from their

# Description
in order to make the charpage for Windows as general as possible, `chcp`
will only run on Windows when `--charpage` is given an integer.
while i was at it, i fixed the system messages given to
`check-clipboard` because some of the were incorrect => see the second
commit 6865ec9a5
# User-Facing Changes
this is a breaking change as users relying on the fact that `std clip`
changed the page to `65001` by itself is not true anymore => they will
have to add `--charpage 65001`.

# Description
This PR updates some `Example` tests so that they work again. The only
one I couldn't figure out is the one in the `filter` command. It should
work but does not. However, I left the test in because it's valuable, it
just has a `None` result. I'd like to fix this but I'm not sure how.

# Description
this PR
- prints a colorful warning when a user uses either `--format` or
`--list` on `into datetime`
- does NOT remove the features for now, i.e. the two options still work
- redirect to the `format date` command instead
i propose to
- land this now
- prepare a removal PR right after this
- land the removal PR in between 0.84 and 0.85
# User-Facing Changes
`into datetime --format` and `into datetime --list` will be deprecated
in 0.85.

Winget Releaser now supports non-Windows runners, and `ubuntu-latest` is
generally faster.
# Description
* All output of `scope` commands is sorted by the "name" column. (`scope
externs` and some other commands had entries in a weird/random order)
* The output of `scope externs` does not have extra newlines (that was
due to wrong usage creation of known externals)
# Description
As described in https://github.com/nushell/nushell/issues/9912, the
`http` command could display the request headers with the `--full` flag,
which could help in debugging the requests. This PR adds such
functionality.
# User-Facing Changes
If `http get` or other `http` command which supports the `--full` flag
is invoked with the flag, it used to display the `headers` key which
contained an table of response headers. Now this key contains two nested
keys: `response` and `request`, each of them being a table of the
response and request headers accordingly.
# Description
This PR enables `select` to take a constructed list of columns as a
variable.
```nushell

╭#┬───name───┬type╮

# Description
In the past we named the process of completely removing a command and
providing a basic error message pointing to the new alternative
"deprecation".
But this doesn't match the expectation of most users that have seen
deprecation _warnings_ that alert to either impending removal or
discouraged use after a stability promise.
# User-Facing Changes
Command category changed from `deprecated` to `removed`

# Description
I've been investigating the [issue
mentioned](https://github.com/nushell/nushell/pull/9976#issuecomment-1673290467)
in my prev pr and I've found that plugin.nu file that is used to cache
plugins signatures gets overwritten on every nushell startup and that
may actually mess up with the file content if 2 or more instances of
nushell will run simultaneously.
To reproduce:
1. register at least 2 plugins in your local nushell
2. remember how many entries you have in plugin.nu with `open
$nu.plugin-path | find nu_plugin`
3. run
- either `cargo test` inside nushell repo

# Solution
In this pr I've refactored the code of handling the `register` command
to minimize code duplications and make sure that overwrite of
`plugin.nu` file is happen only when user calls the command and not on
nu startup
Another option would be to use temp `plugin.nu` when running tests, but
as the issue actually can affect users I've decided to prevent
unnecessary writing at all. Although having isolated `plugin.nu` still
worth of doing
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

It changes the behaviour actually as the call `register <plugin>
<signature>` now doesn't updates `plugin.nu` and just reads signatures
to the memory. But as I understand that kind of call with explicit
signature is meant to use only by nushell itself in the `plugin.nu` file
only. I've asked about it in
[discord](https://discordapp.com/channels/601130461678272522/615962413203718156/1140013448915325018)

Actually, I think the way plugins are stored might be reworked to
prevent or mitigate possible issues further:
- problem with writing to file may still arise if we try to register in
parallel as several instances will write to the same file so the lock
for the file might be required
- using additional parameters to command like `register` to implement
some internal logic could be misleading to the users
- `register` call actually affects global state of nushell that sounds a
little bit inconsistent with immutability and isolation of other parts
of the nu. See issues
[1](https://github.com/nushell/nushell/issues/8581),

I noticed that`watch` was not catching all filesystem changes, because

This was happening on Ubuntu 23.04, ext4.
# Description
This PR does three related changes:
* Keeps the originally declared name in help outputs.
* Updates the name of the commands called `main` in the user script to
the name of the script.
* Fixes the source of signature information in multiple places. This
allows scripts to have more complete help output.
Combined, the above allow the user to see the script name in the help
output of scripts, like so:
NOTE: You still declare and call the definition `main`, so from inside
the script `main` is still the correct name. But multiple folks agreed
that seeing `main` in the script help was confusing, so this PR changes
that.
# User-Facing Changes
One potential minor breaking change is that module renames will be shown
as their originally defined name rather than the renamed name. I believe
this to be a better default.

# Description
Those two commands are very complementary to `into duration` and `into
filesize` when you want to coerce a particular string output.
This keeps the old `format` command with its separate formatting syntax
still in `nu-cmd-extra`.

`format filesize` is back accessible with the default build. The new
`format duration` command is also available to everybody

# Description
in its documentation, `input list` says it only accepts the following
signatures
- `list<any> -> list<any>`
- `list<string> -> string`
however this is incorrect as the following is allowed and even in the
help page
```nushell
[1 2 3] | input list # -> returns an `int`
```
this PR fixes the signature of `input list`.
- with no option or `--fuzzy`, `input list` takes a `list<any>` and
outputs a single `any`
- with `--multi`, `input list` takes a `list<any>` and outputs a
`list<any>`
# User-Facing Changes
the input output signature of `input list` is now
```
╭───┬───────────┬───────────╮
│ # │ input │ output │

│ 0 │ list<any> │ list<any> │

Context from Discord:

I was working on Nu for the first time in a while and I noticed that
sometimes rust-analyzer takes a really long time to run `cargo check` on
the entire workspace. I dug in and it was checking a bunch of
dataframe-related dependencies even though the `dataframe` feature is
not built by default.
It looks like this is a regression of sorts, introduced by
https://github.com/nushell/nushell/pull/9241. Thankfully the fix is
pretty easy, we can make it so everything important in
`nu-cmd-dataframe` is only used when the `dataframe` feature is enabled.

This PR should close#8036, #9028 (in the negative) and #9118.
Fix for #9118 is a bit pedantic. As reported, the issue is:
```
> 2023-05-07T04:08:45+12:00 - 2019-05-10T09:59:12+12:00
3yr 12month 2day 18hr 9min 33sec
```
with this PR, you now get:
```

208wk 1day 18hr 9min 33sec
```
Which is strictly correct, but could still fairly be called "weird date
arithmetic".
# Description
* [x] Abide by constraint that Value::Duration remains a number of
nanoseconds with no additional fields.
* [x] `to_string()` only displays weeks .. nanoseconds. Duration doesn't
have base date to compute months or years from.
* [x] `duration | into record` likewise only has fields for weeks ..
nanoseconds.
* [x] `string | into duration` now accepts compound form of duration
to_string() (e.g '2day 3hr`, not just '2day')
* [x] `duration | into string` now works (and produces the same
representation as to_string(), which may be compound).
# User-Facing Changes
## duration -> string -> duration
Now you can "round trip" an arbitrary duration value: convert it to a
string that may include multiple time units (a "compound" value), then
convert that string back into a duration. This required changes to
`string | into duration` and the addition of `duration | into string'.
```
> 2day + 3hr
2day 3hr # the "to_string()" representation (in this case, a compound value)
> 2day + 3hr | into string
2day 3hr # string value
> 2day + 3hr | into string | into duration
2day 3hr # round-trip duration -> string -> duration
```
Note that `to nuon` and `from nuon` already round-tripped durations, but
use a different string representation.
## potentially breaking changes
* string rendering of a duration no longer has 'yr' or 'month' phrases.
* record from `duration | into record` no longer has 'year' or 'month'
fields.
The excess duration is all lumped into the `week` field, which is the
largest time unit you can
convert to without knowing the datetime from which the duration was
calculated.
Scripts that depended on month or year time units on output will need to
be changed.
### Examples
```
> 365day
52wk 1day
## Used to be:
## 1yr
> 365day | into record
╭──────┬────╮
│ week │ 52 │
│ day │ 1 │
│ sign │ + │
╰──────┴────╯
## used to be:
##╭──────┬───╮
##│ year │ 1 │

##╰──────┴───╯
> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns)
56wk 6day 6hr 7min 8sec 9ms 10µs 11ns
## used to be:
## 1yr 1month 3day 6hr 7min 8sec 9ms 10µs 11ns
## which looks reasonable, but was actually only correct in 75% of the years and 25% of the months in the last 4 years.
> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns) | into record
╭─────────────┬────╮
│ week │ 56 │

│ second │ 8 │
│ millisecond │ 9 │

╰─────────────┴────╯
```
Strictly speaking, these changes could break an existing user script.
Losing years and months as time units is arguably a regression in
behavior.
Also, the corrected duration calculation could break an existing script
that was calibrated using the old algorithm.

# Description
This PR adds back the functionality to auto-expand tables based on the
terminal width, using the logic that if the terminal is over 100 columns
to expand.
This sets the default config value in both the Rust and the default
nushell config.
To do so, it also adds back the ability for hooks to be strings of code
and not just code blocks.
Fixed a couple tests: two which assumed that the builtin display hook
didn't use a table -e, and one that assumed a hook couldn't be a string.

- will force Nushell to recompile the `version` information correctly
this PR adds a call to `touch` on that file to `toolkit install`.

@jntrnr and I discussed the fact that we can now *graduate* nuon to be a
first class citizen...
This PR moves
* from nuon
* to nuon
out of the *experimental* stage and into *formats*
# Description
Add a few tests to ensure that you can add subcommands to scripts. We've
supported this for a long time, though I'm not sure if anyone has
actually tried it. As we weren't testing the support, this PR adds a few
tests to ensure it stays working.
Example script subcommand:
```
def "main addten" [x: int] {
print ($x + 10)
}
```
then call it with:
```
> nu ./script.nu addten 5
```

In an effort to go through and review all of the remaining commands to
find anything else that could possibly
be moved to *nu-cmd-extra*
I noticed that there are still some commands that have not been
categorized...
I am going to *Categorize* the remaining commands that still *do not
have Category homes*
In PR land I will call this *Categorification* as a play off of
*Cratification*
* str substring
* str trim
* str upcase
were in the *default* category because for some reason they had not yet
been categorized.
I went ahead and moved them to the
```rust
.category(Category::Strings)
```
I am moving the following str case commands to nu-cmd-extra (as
discussed in the core team meeting the other day)
* camel-case
* kebab-case
* pascal-case
* screaming-snake-case
* snake-case
* title-case
# Description
This PR adds a keybinding in the rust code for `search-history` aka
reverse-search as `ctrl+q` so it does not overwrite `history-search`
with `ctrl+r` as it does now.
This PR supercedes #9862. Thanks to @SUPERCILEX for bringing this to our
attention.

Currently `parse` acts like a `.filter` over an iterator, except that it
emits `None` for elements that can't be parsed. This causes consumers of
the adapted iterator to stop iterating too early. The correct behaviour
is to keep pulling the inner iterator until either the end of it is
reached or an element can be parsed.

# Description
Currently, foreground process management is disabled for macOS, since
the original code had issues (see #7068).
This PR re-enables process management on macOS in combination with the
changes from #9693.
# User-Facing Changes
Fixes hang on exit for nested nushells on macOS (issue #9859). Nushell
should now manage processes in the same way on macOS and other unix
systems.

fix#9796
Sorry that you've had the issues.
I've actually encountered them yesterday too (seems like they have
appeared after some refactoring in the middle) but was not able to fix
that rapid.
Created a bunch of tests.
cc: @fdncred
Note:
This option will be certainly slower then a default ones. (could be
fixed but ... maybe later).
Maybe it shall be cited somewhere.
PS: Haven't tested on a wrapped/expanded tables.

# Description
https://github.com/nushell/nushell/pull/9907 removed the front space
from all `PROMPT_INDICATOR`s but this is not what the default behaviour
of Nushell is, i.e. in `nu --no-config-file`.
this PR
- removes the space that is prepended by Nushell before the prompt
indicator to match the `default_env.nu`
- swaps INSERT and NORMAL in the Rust code to match the `:` and `>`
respectively in `default_env.nu`
## 🔍 try the changes
> **Warning**
> i had to comment out in my config all the `$env.PROMPT_INDICATOR... =
...` to avoid these variables to propagate to `cargo run -- -n`
in either `cargo run -- -n` or `cargo run -- --config
crates/nu-utils/src/sample_config/default_config.nu --env-config
crates/nu-utils/src/sample_config/default_env.nu`,
- see `/path/to/nushell>` as the prompt with the default `emacs` edit
mode
- run `$env.config.edit_mode = vi`
- see `/path/to/nushell:` as the INSERT prompt in Vi mode
- press Escape to go into NORMAL mode
- see `/path/to/nushell>` as the NORMAL prompt in Vi mode
- press I to go back into INSERT mode
- see `/path/to/nushell:` as the INSERT prompt in Vi mode
# User-Facing Changes
the prompts in `nu --no-config-file` and `nu --config default_config.nu

This is just draft since we're seeing some issues with the latest fixes
to table drawing that just landed with #9796. We're hoping to get these
fixed, but if we're not able to fix them before the next release, we'll
need to revert (hence this PR, just in case we need it).

Closes: #9891
I also think it's good to keep command name consistency.
And moving `date format` to deprecated.
# User-Facing Changes
Running `date format` will lead to deprecate message:

# Description
This PR aligns the default config in the Rust code to the default config
in the nushell file.
To do so, it removes closures from the default file, opting instead to
pick a simple style as default. This allows easier maintenance of both
Rust and Nushell code without removing the ability to use closures for
styling in your configuration.
The default theme is now "dark mode" in both the Rust and nushell config
code.

Relative: #8248
After this pr, user can define const variable inside a module.
And user can export const variables, the following screenshot shows how
it works (it follows
https://github.com/nushell/nushell/issues/8248#issuecomment-1637442612):
## About the change
1. To make module support const, we need to change `parse_module_block`
to support `const` keyword.
2. To suport export `const`, we need to make module tracking variables,
so we add `variables` attribute to `Module`
3. During eval, the const variable may not exists in `stack`, because we
don't eval `const` when we define a module, so we need to find variables
which are already registered in `engine_state`
## One more thing to note about the const value.
Consider the following code
```
module foo { const b = 3; export def bar [] { $b } }
use foo bar
const b = 4;
bar
```
The result will be 3 (which is defined in module) rather than 4. I think
it's expected behavior.
It's something like [dynamic
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Dynamic-Binding-Tips.html)
vs [lexical
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Lexical-Binding.html)
in lisp like language, and lexical binding should be right behavior
which generates more predicable result, and it doesn't introduce really
subtle bugs in nushell code.
What if user want dynamic-binding?(For example: the example code returns
`4`)
There is no way to do this, user should consider passing the value as
argument to custom command rather than const.
## TODO
- [X] adding tests for the feature.
- [X] support export const out of module to use.

# Description
`Span` is `Copy`, so we probably should not be passing references of
`Span` around. This PR replaces all instances of `&Span` with `Span`,
copying spans where necessary.
# User-Facing Changes
This alters some public functions to take `Span` instead of `&Span` as
input. Namely, `EngineState::get_span_contents`,
`nu_protocol::extract_value`, a bunch of the math commands, and
`Gstat::gstat`.
# Description

Before:
`http <subcommand> -H` took a list in the form:
```nushell
[my-header-key-A my-header-value-A my-header-key-B my-header-value-B]
```
Now:
In addition to the old format, Records can be passed, For example,
```nushell
> let reqHeaders = {
Cookie: "acc=barfoo",
User-Agent: "Mozilla/7.0 (Windows NT 33.0; Win64; x64) AppleWebKit/1038.90 (KHTML, like Gecko)"
}
> http get -H $reqHeaders https://example.com
```
is now equivalent to
```nushell
http get -H [Cookie "acc=barfoo" User-Agent "Mozilla/7.0 (Windows NT 33.0; Win64; x64) AppleWebKit/1038.90 (KHTML, like Gecko)"] https://example.com
```
# User-Facing Changes
No breaking changes, but Records can now also be passed to `http

# Description
Add `format duration` cmd to choose output unit.
This takes the previous `into duration --convert ...` behavior which
returned a string into its own `format duration` command.
This was suprising and not fitting with the general type signature for
the `into ...` commands.
This command for now lives in the `nu-cmd-extra` nursery.
# User-Facing Changes
## Breaking change
Removes formatting behavior from `into duration`
Now use `format duration` instead of `into duration --convert`
## Usage:
```
1sec | format duration us # Output data in microseconds
"2ms" | into duration | format duration sec # go from string to string
```

This command will always return a list, either because there are
multiple entries with the same frequency or just one.
It's implementation doesn't care about the composition of types as long
as they are number like, can be heterogeneous, will report
independently.

Still support forming the median over homogeneous lists of `Duration` or
`Filesize`. Don't advertise `list<any>` as this can become funky when
given an even number of elements...

# Description
before 0.83.0, `print` used to allow piping data into it, e.g.
```nushell
"foo" | print
```
instead of
```nushell
print "foo"
```
this PR enables the `any -> nothing` input / output type to allow this
again.
i've double checked and `print` is essentially the following snippet
```rust
if !args.is_empty() {
for arg in args {
arg.into_pipeline_data()
.print(engine_state, stack, no_newline, to_stderr)?;
}
} else if !input.is_nothing() {
input.print(engine_state, stack, no_newline, to_stderr)?;
}
```
1. the first part is for `print a b c`
2. the second part is for `"foo" | print`
# User-Facing Changes

# Description
Previously, we had a bug slip in about implied collection caused by
`$in`, that this output type would be of type `string`.
The type system fixes in 0.83 now make this more visible and cause
issues. This PR changes the output of the implied collection to `any`.
At some point in the future, we may want to carry the type through where
we can, but `any` should unblock using `$in`.

# Description
With the current typechecking logic this property has no effect.
It was only used in the example testing, and provided some indication of
this vectorizing property.
With #9742 all commands that previously declared it have explicit list

it from the signature.
Simplifies the example testing a bit.
# User-Facing Changes

this causes a compile fail, this was already broken by our more
stringent type checking.
This will be a good reminder for plugin authors to update their
signature as well to reflect the more stringent type checking.

### License
## Our Rust style
To make the collaboration on a project the scale of Nushell easy, we want to work towards a style of Rust code that can easily be understood by all of our contributors. We conservatively rely on most of [`clippy`s suggestions](https://github.com/rust-lang/rust-clippy) to get to the holy grail of "idiomatic" code. Good code in our eyes is not the most clever use of all available language features or with the most unique personal touch but readable and strikes a balance between being concise, and also unsurprising and explicit in the places where it matters.
One example of this philosophy is that we generally avoid to fight the borrow-checker in our data model but rather try to get to a correct and simple solution first and then figure out where we should reuse data to achieve the necessary performance. As we are still pre-1.0 this served us well to be able to quickly refactor or change larger parts of the code base.
### Generally discouraged
#### `+nightly` language features or things only available in the most recent `+stable`
To make life for the people easier that maintain the Nushell packages in various distributions with their own release cycle of `rustc` we typically rely on slightly older Rust versions. We do not make explicit guarantees how far back in the past we live but you can find out in our [`rust-toolchain.toml`](https://github.com/nushell/nushell/blob/main/rust-toolchain.toml)
(As a rule of thumb this has been typically been approximately 2 releases behind the newest stable compiler.)
The use of nightly features is prohibited.
#### Panicking
As Nushell aims to provide a reliable foundational way for folks to interact with their computer, we cannot carelessly crash the execution of their work by panicking Nushell.
Thus panicking is not an allowed error handling strategy for anything that could be triggered by user input OR behavior of the outside system. If Nushell panics this is a bug or we are against all odds already in an unrecoverable state (The system stopped cooperating, we went out of memory). The use of `.unwrap()` is thus outright banned and any uses of `.expect()` or related panicking macros like `unreachable!` should include a helpful description which assumptions have been violated.
#### `unsafe` code
For any use of `unsafe` code we need to require even higher standards and additional review. If you add or alter `unsafe` blocks you have to be familiar with the promises you need to uphold as found in the [Rustonomicon](https://doc.rust-lang.org/nomicon/intro.html). All `unsafe` uses should include `// SAFETY:` comments explaining how the invariants are upheld and thus alerting you what to watch out for when making a change.
##### FFI with system calls and the outside world
As a shell Nushell needs to interact with system APIs in several places, for which FFI code with unsafe blocks may be necessary. In some cases this can be handled by safe API wrapper crates but in some cases we may choose to directly do those calls.
If you do so you need to document the system behavior on top of the Rust memory model guarantees that you uphold. This means documenting whether using a particular system call is safe to use in a particular context and all failure cases are properly recovered.
##### Implementing self-contained data structures
Another motivation for reaching to `unsafe` code might be to try to implement a particular data structure that is not expressible on safe `std` library APIs. Doing so in the Nushell code base would have to clear a high bar for need based on profiling results. Also you should first do a survey of the [crate ecosystem](https://crates.io) that there doesn't exist a usable well vetted crate that already provides safe APIs to the desired datastructure.
##### Make things go faster by removing checks
This is probably a bad idea if you feel tempted to do so. Don't
#### Macros
Another advanced feature people feel tempted to use to work around perceived limitations of Rusts syntax and we are not particularly fans of are custom macros.
They have clear downsides not only in terms of readability if they locally introduce a different syntax. Most tooling apart from the compiler will struggle more with them. This limits for example consistent automatic formatting or automated refactors with `rust-analyzer`.
That you can fluently read `macro_rules!` is less likely than regular code. This can lead people to introduce funky behavior when using a macro. Be it because a macro is not following proper hygiene rules or because it introduces excessive work at compile time.
So we generally discourage the addition of macros. In a lot of cases your macro may start do something that can be expressed with functions or generics in a much more reusable fashion.
The only exceptions we may allow need to demonstrate that the macro can fix something that is otherwise extremely unreadable, error-prone, or consistently worse at compile time.
### Things we want to get better at
These are things we did pretty liberally to get Nushell off the ground, that make things harder for a high quality stable product. You may run across them but shouldn't take them as an endorsed example.
#### Liberal use of third-party dependencies
The amazing variety of crates on [crates.io](https://crates.io) allowed us to quickly get Nushell into a feature rich state but it left us with a bunch of baggage to clean up.
Each dependency introduces a compile time cost and duplicated code can add to the overall binary size. Also vetting more for correct and secure implementations takes unreasonably more time as this is also a continuous process of reacting to updates or potential vulnerabilities.
Thus we only want to accept dependencies that are essential and well tested implementations of a particular requirement of Nushells codebase.
Also as a project for the move to 1.0 we will try to unify among a set of dependencies if they possibly implement similar things in an area. We don't need three different crates with potentially perfect fit for three problems but rather one reliable crate with a maximized overlap between what it provides and what we need.
We will favor crates that are well tested and used and promise to be more stable and still frequently maintained.
#### Deeply nested code
As Nushell uses a lot of enums in its internal data representation there are a lot of `match` expressions. Combined with the need to handle a lot of edge cases and be defensive about any errors this has led to some absolutely hard to read deeply nested code (e.g. in the parser but also in the implementation of several commands).
This can be observed both as a "rightward drift" where the main part of the code is found after many levels of indentations or by long function bodies with several layers of branching with seemingly repeated branching inside the higher branch level.
This can also be exacerbated by "quick" bugfixes/enhancements that may just try to add a special case to catch a previously unexpected condition. The likelihood of introducing a bug in a sea of code duplication is high.
To combat this, consider using the early-`return` pattern to reject invalid data early in one place instead of building a tree through Rust's expression constructs with a lot of duplicated paths. Unpacking data into a type that expresses that the necessary things already have been checked and using functions to properly deal with separate and common behavior can also help.
