# Description
Reallow the commands that take cellpaths as rest parameters to operate
on table input data.
Went through all commands returned by
```
scope commands |
filter { |cmd| $cmd.signatures |
values |
any {|sig| $sig |
any {|$sig| $sig.parameter_type == rest and $sig.syntax_shape ==
cellpath }
}
} | get name
```
Only exception to that was `is-empty` that returns a bool.
# User-Facing Changes
Same table operations as in `0.82` should still be possible
Mitigates effects of #9680
# Description
If we reach the conclusion that the fields of a list are of `Type::Any`
there is no need to continue as the type will remain `Type::Any`
This should improve runtimes of `Value.get_type()` for lists with mixed
types.
# User-Facing Changes
None, a speedup in some cases.
# Tests + Formatting
Relies on existing tests
# Description
Those two commands did *not* vectorize over the input in the pure sense
as they performed a flat map. Now they return a list for each string
that gets split by them.
```
["foo" "bar"] | split chars
```

# Description
All commands that declared `.vectorizes_over_list(true)` now also
explicitly declare the list form of their scalar types.
- Explicit in/out list signatures for nu-command
- Explicit in/out list signatures for nu-cmd-extra
- Add comments about cellpath behavior that is still unresolved
# User-Facing Changes
Our type signatures will now be more explicit about which commands
support vectorization over lists.
On the downside this is a bit more verbose and less systematic.
# Description
Don't just use `List<Any>`, be precise for the vectorized form as well.
# User-Facing Changes
More explicit albeit verbose type information in the signature
should close https://github.com/nushell/nushell/issues/9774
# Description
given the help page of `into datetime`,
```
Parameters:
...rest <cellpath>: for a data structure input, convert data at the given cell paths
```
it looks like `into datetime` should accept tables as input 🤔
this PR
- adds the `table -> table` signature to `into datetime`
- adds a test to make sure the behaviour stays there

# Description
This PR ensures functions exist to extract and create each and every
`Value` case. It also renames `Value::boolean` to `Value::bool` to match
`Value::test_bool`, `Value::as_bool`, and `Value::Bool`. Similarly,
`Value::as_integer` was renamed to `Value::as_int` to be consistent with
`Value::int`, `Value::test_int`, and `Value::Int`. These two renames can
be undone if necessary.
# User-Facing Changes
No user facing changes, but two public functions were renamed which may
affect downstream dependents.

I added a new capability to `bracoxide` which is for `brace expansion`
(it's almost like bash brace expressions).
Anyway, this change adds this capability:
`A{,B,C} | str expand`, returns:
```md
- A
- AB
- AC
```
`A{B,,C} | str expand`, returns:
```md
- AB
- A
- AC
```
`A{B,C,} | str expand`, returns:
```md
- AB
- AC
- A
```
Updated examples, according to the new feature.
# Description
in the help page of `metadata`, there is the following example
```nushell
ls | metadata
```
which gives the following error
```

╭─[entry #2:1:1]

this PR adds `any -> record` to the signatures of `metadata` to allow
the use of that kind of example.

# Description
This fixes the variable capture logic for closures in two cases:
* Closures inside of closures did not properly register the closures (or
lack thereof) in the outer closure
* Closures which called their inner closures before definition did not
properly calculate the closures of the outer closure
Example of the first case:
```
do { let b = 3; def c [] { $b }; c }
```
Example of the second case (notice `c` is called before it is defined):
```
do { let b = 3; c; def c [] { $b }; c }
```
# User-Facing Changes
This should strictly allow closures to work more correctly.

## About the change
Before the pr, nushell only parse redirection target as a string(through
`parse_string` call).
In the pr, I'm trying to make the value more generic(using `parse_value`
with `SyntaxShape::Any`)
And during eval stage, we guard it to only eval `String`,
`StringInterpolation`, `FullCellPath`, `FilePath`, so other type of
redirection target like `1ms` won't be permitted.
# User-Facing Changes
After the pr: redirection support something like the following:
1. `let a = "x"; cat toolkit.nu o> $a`
2. `let a = "x"; cat toolkit.nu o> $"($a).txt"`
3. `cat toolkit.nu out> ("~/a.txt" | path expand)`
# Description
Thie PR adds `Type::Range` input to `par-each` to allow `1..3 | do
something` again.

# Description
After #9693, tests will stop and go into the background if run locally
in bash, since nushell is being run in interactive mode even though
`--testbin` is supplied. This makes nushell run in non-interactive mode
if `--testbin` is supplied.
# Description
We only used this procmacro crate in one place to generate two trivial
getters. Straightforward to replace. Should reduce test-compilation
requirements a bit.

# Description
this PR updates the `default_config.nu` config file and the `config.rs`
module in `nu_protocol` so that the default behaviour of Nushell,
without any config, and the one with `default_config.nu` and
`default_env.nu` are the same.
## changelog
- 3e2bfc9bb: copy the structure of `default_config.nu` inside the
implementation of `Default` in the `config.rs` module for easier check
of the default values
- e25e5ccd6: sync all the *simple* config fields, i.e. the
non-structured ones
- ae7e8111c: set the `display_output` hook to always run `table`
- a09a1c564: leave only the default menus => i've removed
`commands_menu`, `vars_menu` and `commands_with_description`
## todo
- [x] ~~check the defaults in `$env.config.explore`~~ done in 173bdbba5
and b9622084c
- [x] ~~check the defaults in `$env.config.color_config`~~ done in
c411d781d => the theme is now `{}` by default so that it's the same as
the default one with `--no-config`
- [x] ~~check the defaults `$env.config.keybindings`~~ done in 715a69797
- already available with the selected mode: `completion_previous`,
`next_page`, `undo_or_previous_page`, `yank`, `unix-line-discard` and
`kill-line`, e.g. in *vi* mode, `unlix-line-discard` is done in NORMAL
mode with either `d0` from the end of the line or `dd` from anywhere in
the line and `kill-line` is done in NORMAL mode with `shift + d`. these
bindings are available by default in *emacs* mode as well.
- previously with removed custom menus: `commands_menu`, `vars_menu` and
`commands_with_description`
- [x] ~~check `$env.config.datetime_format`~~ done in 0ced6b8ec => as
there is no *human* format for datetimes, i've commented out both
`$env.config.datetime_format` fields
- [x] ~~fix `default_env.nu`~~ done in 67c215011

# 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
❯ 9..17 | filter {|el| $el mod 2 != 0}

# 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

| 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

# User-Facing Changes
`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 updates `let` and `mut` to allow for any input. This lets them
typecheck any collection they do.
For example, this now compiles:
```
def foo []: [int -> int, string -> int] {
let x = $in
if ($x | describe) == "int" { 3 } else { 4 }
}
100 | foo
```

# 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
Due to a typo? in the
[reference](https://www.gnu.org/software/libc/manual/html_node/Initializing-the-Shell.html)
used to implement SIGTTIN handling, nushell will crash when being sent
to the background from within another shell.
For example, currently in bash:
```bash
$ nu -n &
[1] 176058
$ ERROR: failed to SIGTTIN ourselves
[1]+ Exit 1 nu -n
$
```
Now fixed:
```bash
$ nu -n &
[1] 178788
$ jobs
[1]+ Stopped nu -n
$
```
For further reference, this is how
[fish](493cbeb84c/src/reader.cpp (L2571))
does it.
# User-Facing Changes
Bug fix only -- users should now be able to send nushell to the
background.
# 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 ($x | str starts-with "aaa") { print "bbb" }
}
# 7.
# repeat a string x amount of times
def repeat [arg: string, dupe: int] {
# broke here: 'command does not support range input'
0..<$dupe | reduce -f '' {|i acc| $acc + $arg}
}

# 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.
