# Description
Fixes a regression from #9681 where nushell will attempt to place itself
into the background or take control of the terminal even in
non-interactive mode.
Using the same
[reference](https://www.gnu.org/software/libc/manual/html_node/Initializing-the-Shell.html)
from #6584:
>A subshell that runs *interactively* has to ensure that it has been
placed in the foreground...
>A subshell that runs *non-interactively* cannot and should not support
job control.
`fish`
[code](54fa1ad6ec/src/reader.cpp (L4862))
also seems to follow this.
This *partially* fixes
[9026](https://github.com/nushell/nushell/issues/9026). That is, nushell
will no longer set the foreground process group in non-interactive mode.
# Description
The working directory doesn't have to be set for those tests (or would
be the default anyways). When appropriate also remove calls to the
`pipeline()` function. In most places kept the diff minimal and only
removed the superfluous part to not pollute the blame view. With simpler
tests also simplified things to make them more readable overall (this
included removal of the raw string literal).
Work for #8670
# Description
This PR allows `Type::Range` on the `filter` command so you can do
things like this:
```nushell

# Description
i have the following command that should give a table of all the mounted
devices with information about their sizes, etc, etc... a glorified
output for the `df -h` command:
```nushell
def disk [] {
df -h
| str replace "Mounted on" "Mountpoint"
| detect columns
| rename filesystem size used avail used% mountpoint
| into filesize size used avail
| upsert used% {|it| 100 * (1 - $it.avail / $it.size)}
}
```
this should work given the first example of `into filesize`
```nushell
Convert string to filesize in table
> [[bytes]; ['5'] [3.2] [4] [2kb]] | into filesize bytes
```
## before this PR
it does not even parse
```nushell
Error: nu::parser::input_type_mismatch
× Command does not support table input.
╭─[entry #1:5:1]
5 │ | rename filesystem size used avail used% mountpoint

· ╰── command doesn't support table input
7 │ | upsert used% {|it| 100 * (1 - $it.avail / $it.size)}
╰────
```
> **Note**
> this was working before the recent input / output type changes
## with this PR
it parses again and gives
```nushell
> disk | where mountpoint == "/" | into record

`into filesize` works back with tables and this effectively fixes the
doc.
# Tests + Formatting

## description
this pr adds [match
guards](https://doc.rust-lang.org/reference/expressions/match-expr.html#match-guards)
to match patterns
```nushell
match $x {
_ if $x starts-with 'nu' => {},
$x => {}
}
```
these work pretty much like rust's match guards, with few limitations:
1. multiple matches using the `|` are not (yet?) supported
```nushell
match $num {
0 | _ if (is-odd $num) => {},
_ => {}
}
```
2. blocks cannot be used as guards, (yet?)
```nushell
match $num {
$x if { $x ** $x == inf } => {},
_ => {}
}
```

# Description
This adds input/output types to custom commands. These are input/output
pairs that related an input type to an output type.
For example (a single int-to-int input/output pair):
```
def foo []: int -> int { ... }
```
You can also have multiple input/output pairs:
```
def bar []: [int -> string, string -> list<string>] { ... }
```
These types are checked during definition time in the parser. If the
block does not match the type, the user will get a parser error.
This `:` to begin the input/output signatures should immediately follow
the argument signature as shown above.
The PR also improves type parsing by re-using the shape parser. The
shape parser is now the canonical way to parse types/shapes in user
code.
This PR also splits `extern` into `extern`/`extern-wrapped` because of
the parser limitation that a multi-span argument (which Signature now
is) can't precede an optional argument. `extern-wrapped` now takes the
required block that was previously optional.
# User-Facing Changes
The change to `extern` to split into `extern` and `extern-wrapped` is a
breaking change.

# Description
This PR fixes some problems I found in scripts by adding some additional
input_output_types.
Here's a list of nushell scripts that it fixed. Look for `# broke here:`
below.
This PR fixes 3, 4, 6, 7 by adding additional input_output_types. 1 was
fixed by changing the script. 2. just doesn't work anymore because mkdir
return type has changed. 5, is a problem with the script, the datatype
for `...rest` needed to be removed.
```nushell
# 1.
def terminal-size [] {
let sz = (input (ansi size) --bytes-until 'R')
# $sz should look like this
# Length: 9 (0x9) bytes | printable whitespace ascii_other non_ascii
# 00000000: 1b 5b 33 38 3b 31 35 30 52 •[38;150R
let sz_len = ($sz | bytes length)
# let's skip the esc[ and R
let r = ($sz | bytes at 2..($sz_len - 2) | into string)
# $r should look like 38;150
# broke here: because $r needed to be a string for split row
let size = ($r | split row ';')
# output in record syntax
{
rows: ($size | get 0)
columns: ($size | get 1)
}
}
# 2.
# make and cd to a folder
def-env mkcd [name: path] {
# broke here: but apparently doesn't work anymore
# It looks like mkdir returns nothing where it used to return a value
cd (mkdir $name -v | first)
}
# 3.
# changed 'into datetime'
def get-monday [] {
(seq date -r --days 7 |
# broke here: because into datetime didn't support list input
into datetime |
where { |e|
($e | date format %u) == "1" }).0 |
date format "%Y-%m-%d"
}
# 4.
# Delete all branches that are not in the excepts list
# Usage: del-branches [main]
def del-branches [
excepts:list # don't delete branch in the list
--dry-run(-d) # do a dry-run
] {
let branches = (git branch | lines | str trim)
# broke here: because str replace didn't support list<string>
let remote_branches = (git branch -r | lines | str replace '^.+?/' '' | uniq)
if $dry_run {
print "Starting Dry-Run"
} else {
print "Deleting for real"
}
$branches | each {|it|
if ($it not-in $excepts) and ($it not-in $remote_branches) and (not ($it | str starts-with "*")) {
# git branch -D $it
if $dry_run {
print $"git branch -D ($it)"
} else {
print $"Deleting ($it) for real"
#git branch -D $it
}
}
}
}
# 5.
# zoxide script
def-env __zoxide_z [...rest] {
# `z -` does not work yet, see https://github.com/nushell/nushell/issues/4769
# broke here: 'append doesn't support string input'
let arg0 = ($rest | append '~').0
# broke here: 'length doesn't support string input' so change `...rest:string` to `...rest`
let path = if (($rest | length) <= 1) and ($arg0 == '-' or ($arg0 | path expand | path type) == dir) {
$arg0
} else {
(zoxide query --exclude $env.PWD -- $rest | str trim -r -c "\n")
}
cd $path
}
# 6.
def a [] {
let x = (commandline)
if ($x | is-empty) { return }
# broke here: because commandline was previously only returning Type::Nothing
if not ($x | str starts-with "aaa") { print "bbb" }
}
# 7.
# repeat a string x amount of times
def repeat [arg: string, dupe: int] {
# broke here: 'command does not support range input'

# Description
This PR tights input/output type-checking a bit more. There are a lot of
commands that don't have correct input/output types, so part of the
effort is updating them.
This PR now contains updates to commands that had wrong input/output
signatures. It doesn't add examples for these new signatures, but that
can be follow-up work.
# User-Facing Changes
BREAKING CHANGE BREAKING CHANGE
This work enforces many more checks on pipeline type correctness than
previous nushell versions. This strictness may uncover incompatibilities
in existing scripts or shortcomings in the type information for internal
commands.

# Description
Until we bump our minimal Rust version to `1.70.0` we can't use
`std::io::IsTerminal`. The crate `is-terminal` (depending on `rustix` or
`windows-sys`) can provide the same.
Get's rid of the dependency on the outdated `atty` crate.
We already transitively depend on it (e.g. through `miette`)
As soon as we reach the new Rust version we can supersede this with
@nibon7's #9550
Co-authored-by: nibon7 <nibon7@163.com>
# Description
- A new one is the removal of unnecessary `#` in raw strings without `"`
inside.
-
https://rust-lang.github.io/rust-clippy/master/index.html#/needless_raw_string_hashes
- The automatically applied removal of `.into_iter()` touched several
places where #9648 will change to the use of the record API. If
necessary I can remove them @IanManske to avoid churn with this PR.
- Manually applied `.try_fold` in two places
- Removed a dead `if`
- Manual: Combat rightward-drift with early return
# Description
This extends the syntax fix for `let` (#9589) to `mut` as well.
Example: `mut x = "hello world" | str length; print $x`
closes#9634
# User-Facing Changes
`mut` now joins `let` in being able to be assigned from a pipeline

The following math commands are being moved to nu-cmd-extra
* cos
* cosh
* egamma
* phi
* pi
* sin
* sinh
* tan
* tanh
* tau
For now I think we have most of the obvious commands moved over based on
@sholderbach this should cover moving the "high school" commands..
>>Yeah I think this rough separation into "high school" math in extra
and "middle school"/"programmer" math in the core makes a ton of sense.
And to reference the @fdncred list from
https://github.com/nushell/nushell/pull/9647#issuecomment-1629498812
* arccos
* arccosh
* arcsin
* arcsinh
* arctan
* arctanh
The above commands are being ported over to nu-cmd-extra
I initially moved all of the math commands over but there are some
issues with the tests...
So we will move them over slowly --- and actually I kind of like this
idea better...
Because some of the math commands we might want to leave in the core
nushell...
Stay tuned...

# Description
Apart from `polars` (only used with `--features dataframe`) and the
dev-dependencies our deps use `indexmap 2.0`.
Thus the default or `extra` `cargo build` will reduce deps.
This also will help deduplicating `hashbrown` and `ahash`.
For #8060
- Bump `indexmap` to 2.0
- Remove unneeded `serde` feature from `indexmap`

# Description
follow up to #8529 and #8914
this works very similarly to record annotations, only difference being
that
```sh
table<name: string>
^^^^ ^^^^^^
| |
| represents the type of the items in that column
|
represents the column name
```
more info on the syntax can be found
[here](https://github.com/nushell/nushell/pull/8914#issue-1672113520)
# User-Facing Changes
**[BREAKING CHANGE]**
this change adds a field to `SyntaxShape::Table` so any plugins that
used it will have to update and include the field. though if you are
unsure of the type the table expects, `SyntaxShape::Table(vec![])` will
suffice
# Description
This fixes the `headers` command handling of missing values (issue
#9602). Previously, each row in the table would have its columns set to
be exactly equal to the first row even if it had less columns than the
first row. This would cause to values magically change their column or
cause panics in other commands if rows ended up having more columns than
values.
# Tests
Added a missing values test for the `headers` command
requires

# ⚙️ Description
in this PR i move the commands we've all agreed, in the core team, to
move out of the core Nushell to the `extra` feature.
> **Warning**
> in the first commits here, i've
> - moved the implementations to `nu-cmd-extra`
> - removed the declaration of all the commands below from `nu-command`
> - made sure the commands were not available anymore with `cargo run --

## the list of commands to move
with the current command table downloaded as `commands.csv`, i've run
```bash
let commands = (
open commands.csv
| where is_plugin == "FALSE" and category != "deprecated"
| select name category "approv. %"
| rename name category approval
| insert treated {|it| (
($it.approval == 100) or # all the core team agreed on them
($it.name | str starts-with "bits") or # see https://github.com/nushell/nushell/pull/9241
($it.name | str starts-with "dfr") # see https://github.com/nushell/nushell/pull/9327
)}
)
```
to preprocess them and then
```bash
$commands | where {|it| (not $it.treated) and ($it.approval == 0)}
```
to get all untreated commands with no approval, which gives

# Description
The `users` crate hasn't been updated for a long time, this PR tries to
replace `users` with `nix`.
See [advisory
page](https://rustsec.org/advisories/RUSTSEC-2023-0040.html) for
additional details.
# Description
in most of the tests for `last` and `first`, we do not need to
- give `cwd` to `nu!`
- use pipeline as the tests are all short pipes
- use `r#" ... "#` as the pipes never contain quotes
this PR removes all these points from the tests for the `last` and
`first` commands.
# Description
Add a `keybindings get` command to listen and get individual "keyboard"
events. This includes different keyboard keys (see example of use) on
seemingly all terminals and mouse, resize, focus and paste events on
some special once. The record returned by this command is similar to
crossterm event structure and is documented in help message. For ease of
use, option `--types` can get a list of event types to filter only
desired events automatically. Additionally `--raw` options displays raw
code of char keys and numeric format of modifier flags.
Example of use, moving a character around a grid with arrow keys:
```nu
def test [] {
mut x = 0
mut y = 0
loop {
clear
$x = ([([$x 4] | math min) 0] | math max)
$y = ([([$y 4] | math min) 0] | math max)

# Description
Hi nushell!
Thanks so much for [adding http headers][headers]! I've been waiting for
this feature for a long time and it's great. However, I found that
`Record` as a return type and using `ureq`'s `response.header` api
results in missing header values when there are multiple with the same
name, as can occur with `set-cookie` and others.
This issue with http has been discussed at length [on
stackoverflow][stackoverflow] and in [`ureq` itself][ureq]. It seems
like concatenating header values with `,` is a common solution, but
tricky especially with `set-cookie` which may contain `,` in the
`Expires` field, as discussed in the former post.
I propose changing the return type to a `List` of `Record` so we can get
all of the header values without relying on ad-hoc mutation. This
solution does not return the headers in the same order as they appear in
the `Response` due to `ureq`'s `Response.all` API, but it's better than
dropping values imo.
This is a **breaking change**. I'm sure `ureq`'s
[`CookieStore`][cookiestore] is a better long-term solution for
returning cookies as a separate record on `http <method>`, but other
headers can be set multiple times as well.
# User-Facing Changes
- Changes the return type of an `http <method>` `header` field from
`Record` to `List` (Table with columns `name` and `value`)
- Returns all values of a header set multiple times instead of just the
first one duplicated
# Implementation
Quick note that running `header_names.dedup()` does not resolve the
necessity to iterate through the previously parsed headers since `dedup`
only removes identical values when they are next to each other in the
`Vec`. You could do a `sort` first, but header ordering can be important
in some cases, so I tried to avoid messing with that more than is
already the case with `Response.all`. Would love to see a better way of
doing this though!
# Tests + Formatting
No tests broke implementing this change. Not sure what endpoint to hit
or mock server to use to verify this in tests. I have some screenshots
to illustrate what I'm talking about.
Before:
> `set-cookie` has the same value for every record field.
> Even if it did not I'm not sure how you would access the different
values since they all have the same key.
After:
> Actual values from the response returned for the same name

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

- Previously, `last` on binary data returned an integer. Now it returns
a binary
- Now, `[] | last` and `[] | first` are both errors.
- Now, `ls | table | first` and `ls | table | last` are both errors.
# Description
This changes the default behaviour of `let` to be able to take a
pipeline as its initial value.
For example:
```
> let x = "hello world" | str length
```
This is a change from the existing behaviour, where the right hand side
is assumed to be an expression. Pipelines are more general, and can be
more powerful.
My google foo is failing me, but this also fixes this issue:
```
let x = foo
```
Currently, this reads `foo` as a bareword that gets converted to a
string rather than running the `foo` command. In practice, this is
really annoying and is a really hard to spot bug in a script.
# User-Facing Changes
BREAKING CHANGE BREAKING CHANGE
`let` gains the power to be assigned via a pipeline. However, this
changes the behaviour of `let x = foo` from assigning the string "foo"
to `$x` to being "run the command `foo` and give the result to `$x`"

# Description
For years, Nushell has used `let-env` to set a single environment
variable. As our work on scoping continued, we refined what it meant for
a variable to be in scope using `let` but never updated how `let-env`
would work. Instead, `let-env` confusingly created mutations to the
command's copy of `$env`.
So, to help fix the mental model and point people to the right way of
thinking about what changing the environment means, this PR removes
`let-env` to encourage people to think of it as updating the command's
environment variable via mutation.
Before:
```
let-env FOO = "BAR"
```
Now:
```
$env.FOO = "BAR"
```
It's also a good reminder that the environment owned by the command is
in the `$env` variable rather than global like it is in other shells.
# User-Facing Changes
BREAKING CHANGE BREAKING CHANGE
This completely removes `let-env FOO = "BAR"` so that we can focus on
`$env.FOO = "BAR"`.

# Description
Closes: #8108
Adding a new `-b` flag to `rename` command. I have thought about making
it as a positional argument, but I don't think it's ok because we alredy
have `...rest` parameters
Here are how they works:
```
# Rename fields based on a given closure
> {a: 1, b: 2} | rename -b {str upcase}
╭───┬───╮
│ A │ 1 │
│ B │ 2 │
╰───┴───╯
# Rename fields based on fields' value
> {a: abc, b: def} | rename -b {|it| $it.value | str upcase}
╭─────┬─────╮
│ ABC │ abc │
│ DEF │ def │
╰─────┴─────╯
```

# Description
This PR fixes a bug that @amtoine found. It adds an input_output type so
that `input list`'s signature supports `string` as an output.
## Before
```
Signatures:
list<any> | input list <string?> -> list<any>
```
## After
```
Signatures:
list<any> | input list <string?> -> list<any>
list<string> | input list <string?> -> <string>
```

# Description
This PR does a few things to help improve type hovers and, in the
process, fixes a few outstanding issues in the type system. Here's a
list of the changes:
* `for` now will try to infer the type of the iteration variable based
on the expression it's given. This fixes things like `for x in [1, 2, 3]
{ }` where `x` now properly gets the int type.
* Removed old input/output type fields from the signature, focuses on
the vec of signatures. Updated a bunch of dataframe commands that hadn't
moved over. This helps tie things together a bit better
* Fixed inference of types from subexpressions to use the last
expression in the block
* Fixed handling of explicit types in `let` and `mut` calls, so we now
respect that as the authoritative type
I also tried to add `def` input/output type inference, but unfortunately
we only know the predecl types universally, which means we won't have
enough information to properly know what the types of the custom
commands are.
# User-Facing Changes
Script typechecking will get tighter in some cases
Hovers should be more accurate in some cases that previously resorted to
any.
