# Description
Simple `parse` patterns let you quickly put together simple parsers, but
sometimes you aren't actually interested in some of the output (such as
variable whitespace). This PR lets you use `{_}` to discard part of the
input.
Example:
```nushell
"hello world" | parse "{foo} {_}"
# => ╭───┬───────╮
# => │ # │ foo │
# => ├───┼───────┤
# => │ 0 │ hello │
# => ╰───┴───────╯
```
here's a simple parser for the `apropops` using the `_` placeholder to
discard the variable whitespace, without needing to resort to a full
regex pattern:
```nushell
apropos linux | parse "{name} ({section}) {_}- {topic}"
# => ╭───┬───────────────────────────────────────┬─────────┬─────────────────────────────────────────────────────────────────────╮
# => │ # │ name │ section │ topic │
# => ├───┼───────────────────────────────────────┼─────────┼─────────────────────────────────────────────────────────────────────┤
# => │ 0 │ PAM │ 8 │ Pluggable Authentication Modules for Linux │
# => │ 1 │ aarch64-linux-gnu-addr2line │ 1 │ convert addresses or symbol+offset into file names and line numbers │
# => │ 2 │ ... │ ... │ ... │
# => │ 3 │ xcb_selinux_set_window_create_context │ 3 │ (unknown subject) │
# => │ 4 │ xorriso-dd-target │ 1 │ Device evaluator and disk image copier for GNU/Linux │
# => ╰───┴───────────────────────────────────────┴─────────┴─────────────────────────────────────────────────────────────────────╯

## Summary
This PR removes the required positional argument from the `which`
command, allowing it to accept input via the spread (`...`) operator.
This enables expressions like:
```nu
[notepad cmd] | which ...$in
```
Previously, this failed due to a missing required positional argument.
The Nushell runtime already handles empty input gracefully, so the
change aligns with existing behavior.
---
## Motivation
Making `which` compatible with splatted input improves composability and
aligns with user expectations in scriptable environments. It supports
patterns where the input may be constructed dynamically or piped in from
earlier commands.
---
## Changes
* Removed the `required` attribute from the positional argument in the
`which` command signature.
* No additional runtime logic required since empty input is handled
gracefully already.
---
## Examples
### Before
```nu
[notepad cmd] | which ...$in
# ❌ Error: Missing required positional argument
```
### After
```nu
[notepad cmd] | which ...$in
# ✅ Executes correctly
```
---
## Testing
* Ran `cargo test --all` and `cargo test -p nu-command`
* Manually tested using spread input with the `which` command
* Confirmed that empty and non-empty inputs behave correctly

# Description
Regex search and search with directly provided search terms used to
follow two different code paths. Now all possible search options get
turned into a regex, with optional additional search options, and
handled using a unified code path which mostly follows the logic of the
current term code path.
# User-Facing Changes
Regex search will now behave in the same way as non-regex search:
- split multiline strings into lists of lines, and filter out the lines
that don't match
- highlight matching string sections (unless --no-highlight flag is
used)
- search through the specified record columns if the --columns flag is
used
The behavior of non-regex search should be unaffected by this commit.

# Description
Currently various commands have differing behavior regarding cell-paths
```nushell
{a: 1, A: 2} | get a A
# => ╭───┬───╮
# => │ 0 │ 2 │
# => │ 1 │ 2 │
# => ╰───┴───╯
{a: 1, A: 2} | select a A
# => ╭───┬───╮
# => │ a │ 1 │
# => │ A │ 2 │
# => ╰───┴───╯
{A: 1} | update a 2
# => Error: nu:🐚:column_not_found
# =>
# => × Cannot find column 'a'
# => ╭─[entry #62:1:1]
# => 1 │ {A: 1} | update a 2
# => · ───┬── ┬
# => · │ ╰── cannot find column 'a'
# => · ╰── value originates here
# => ╰────
```
Proposal: making cell-path access case-sensitive by default and adding
new syntax for case-insensitive parts, similar to optional (?) parts.
```nushell
{FOO: BAR}.foo
# => Error: nu:🐚:name_not_found
# =>
# => × Name not found
# => ╭─[entry #60:1:21]
# => 1 │ {FOO: BAR}.foo
# => · ─┬─
# => · ╰── did you mean 'FOO'?
# => ╰────
{FOO: BAR}.foo!
# => BAR
```
This would solve the problem of case sensitivity for all commands
without causing an explosion of flags _and_ make it more granular
Assigning to a field using a case-insensitive path is case-preserving.
```nushell
mut val = {FOO: "I'm FOO"}; $val
# => ╭─────┬─────────╮
# => │ FOO │ I'm FOO │
# => ╰─────┴─────────╯
$val.foo! = "I'm still FOO"; $val
# => ╭─────┬───────────────╮
# => │ FOO │ I'm still FOO │
# => ╰─────┴───────────────╯
```
For `update`, case-insensitive is case-preserving.
```nushell
{FOO: 1} | update foo! { $in + 1 }
# => ╭─────┬───╮
# => │ FOO │ 2 │
# => ╰─────┴───╯
```
`insert` can insert values into nested values so accessing into existing
columns is case-insensitive, but creating new columns uses the cell-path
as it is.
So `insert foo! ...` and `insert FOO! ...` would work exactly as they do
without `!`
```nushell
{FOO: {quox: 0}}
# => ╭─────┬──────────────╮
# => │ │ ╭──────┬───╮ │
# => │ FOO │ │ quox │ 0 │ │
# => │ │ ╰──────┴───╯ │
# => ╰─────┴──────────────╯
{FOO: {quox: 0}} | insert foo.bar 1
# => ╭─────┬──────────────╮
# => │ │ ╭──────┬───╮ │
# => │ FOO │ │ quox │ 0 │ │
# => │ │ ╰──────┴───╯ │
# => │ │ ╭─────┬───╮ │
# => │ foo │ │ bar │ 1 │ │
# => │ │ ╰─────┴───╯ │
# => ╰─────┴──────────────╯
{FOO: {quox: 0}} | insert foo!.bar 1
# => ╭─────┬──────────────╮
# => │ │ ╭──────┬───╮ │
# => │ FOO │ │ quox │ 0 │ │
# => │ │ │ bar │ 1 │ │
# => │ │ ╰──────┴───╯ │
# => ╰─────┴──────────────╯
```
`upsert` is tricky, depending on the input, the data might end up with
different column names in rows. We can either forbid case-insensitive
cell-paths for `upsert` or trust the user to keep their data in a
sensible shape.
This would be a breaking change as it would make existing cell-path
accesses case-sensitive, however the case-sensitivity is already
inconsistent and any attempt at making it consistent would be a breaking
change.
> What about `$env`?
1. Initially special case it so it keeps its current behavior.
2. Accessing environment variables with non-matching paths gives a
deprecation warning urging users to either use exact casing or use the
new explicit case-sensitivity syntax
3. Eventuall remove `$env`'s special case, making `$env` accesses
case-sensitive by default as well.
> `$env.ENV_CONVERSIONS`?
In addition to `from_string` and `to_string` add an optional field to
opt into case insensitive/preserving behavior.
# User-Facing Changes
- `get`, `where` and other previously case-insensitive commands are now
case-sensitive by default.
- `get`'s `--sensitive` flag removed, similar to `--ignore-errors` there
is now an `--ignore-case` flag that treats all parts of the cell-path as
case-insensitive.
- Users can explicitly choose the case case-sensitivity of cell-path
accesses or commands.

Closes#14469
# Description
- ~~Implement the ``--unit`` conversion in "into int" command~~
- New ``ShellError::InvalidUnit`` unit if users enter wrong units
- Made ``ShellError::CantConvertToDuration`` more generic: became
``CantConvertToUnit``
- Tried to improve the way we parse units and get the supported units.
It's not complete, though, I will continue this refactoring in another
PR. But I already did some small refactorings in the "format duration"
and "format filesize" commands
- Add tests for "format filesize" and "format duration"

# Description
This PR adds lazy closure evaluation to the `default` command (closes
#14160).
- For non-closure values and without providing a column name, `default`
acts the same as before
- The user can now provide multiple column names to populate if empty
- If the user provides a column name, the input must be a record or
list, otherwise an error is created.
- The user can now provide a closure as a default value
- This closure is run without any arguments or input
- The closure is never evaluated if the value isn't needed
- Even when column names are supplied, the closure is only run once (and
cached to prevent re-calling it)
For example:
```nushell
> default { 1 + 2 } # => 3
> null | default 3 a # => previously `null`, now errors
> 1 | default { sleep 5sec; 3 } # => `1`, without waiting 5 seconds
> let optional_var = null; $optional_var | default { input 'Enter value: ' } # => Returns user input
> 5 | default { input 'Enter value: ' } # => `5`, without prompting user
> ls | default { sleep 5sec; 'N/A' } name # => No-op since `name` column is never empty
> ls | default { sleep 5sec; 'N/A' } foo bar # => creates columns `foo` and `bar`; only takes 5 seconds since closure result is cached
# Old behavior is the same
> [] | default 'foo' # => []
> [] | default --empty 'foo' # => 'foo'
> default 5 # => 5
```
# User-Facing Changes
- Users can add default values to multiple columns now.
- Users can now use closures as the default value passed to `default`.
- To return a closure, the user must wrap the closure they want to
return inside another closure, which will be run (`default { $my_closure
}`).

All tests pass.

Thanks for reproducible.
So @Bahex indeed padding was not properly handled.
I am not sure whether there's more issues related to your examples

Also added a test for future regressions (well to be honest didn't
tested that it's failing on main but at least at may catch something)
PS: Also got some panic related to #15138 (which PR fixed) :(
There's nothing on my end stopping me releasing a WASM issue fix; I just

- A few days back I've got this idea regarding recalculus of width.
Now it calculates step by step.
So 1 loop over all data was removed.
All though there's full recalculation in case of `header_on_border`
😞 (can be fixed..... but I decided to be short)
In perfect world it also shall be refactored ......
- Also have done small refactoring to switch build table from
`Vec<Vec<_>>>` to table itself. To hide internals (kind of still there's
things which I don't like).
It touched the `--expand` algorithm lightly you can see the tests
changes.
- And when doing that noticed one more opportunity, to remove HashMap
usage and directly use `tabled::ColoredConfig`. Which reduces copy
operations and allocations.
- And fixed a small issue where trailing column being using deleted
column styles.
To conclude optimizations;
I did small testing and it's not slower.
But I didn't get the faster results either.
But I believe it must be faster well in all cases, I think maybe bigger
tables must be tested.
Maybe someone could have a few runs to compare performance.

# Description
This PR implements an experimental inter-job communication model,
through direct message passing, aka "mail"ing or "dm"ing:
- `job send <id>`: Sends a message the job with the given id, the root
job has id 0. Messages are stored in the recipient's "mailbox"
- `job recv`: Returns a stored message, blocks if the mailbox is empty
- `job flush`: Clear all messages from mailbox
Additionally, messages can be sent with a numeric tag, which can then be
filtered with `mail recv --tag`.
This is useful for spawning jobs and receiving messages specifically
from those jobs.
This PR is mostly a proof of concept for how inter-job communication
could look like, so people can provide feedback and suggestions
Closes #15199
May close#15220 since now jobs can access their own id.

# Description
Try to fixes https://github.com/nushell/nushell/issues/15326 in another
way.
The main point of this change is to avoid duplicate `write` and `close`
a redirected file. So during compile, if compiler know current element
is a sub-expression(defined by private `is_subexpression` function), it
will no longer invoke `finish_redirection`.
In this way, we can avoid duplicate `finish_redirection`.
# User-Facing Changes

Fixes#15559
# Description
The glob command wasn't working correctly with symlinks in the /sys
filesystem. This commit adds a new flag that allows users to explicitly
control whether symlinks should be followed, with special handling for
the /sys directory.
The issue was that the glob command didn't follow symbolic links when
traversing the /sys filesystem, resulting in an empty list even though
paths should be found. This implementation adds a new
`--follow-symlinks` flag that explicitly enables following symlinks. By
default, it now follows symlinks in most paths but has special handling
for /sys paths where the flag is required.
Example:
`
# Before: This would return an empty list on Linux systems
glob /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
# Now: This works as expected with the new flag
glob /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
--follow-symlinks
`
# User-Facing Changes
1. Added the --follow-symlinks (-l) flag to the glob command that allows
users to explicitly control whether symbolic links should be followed
2. Added a new example to the glob command help text demonstrating the
use of this flag
# Tests + Formatting

# Description
Previously, outer joins would remove rows without join columns, since
the "did not match" logic only executed when the row had the join
column.
To solve this, missing join columns are now treated the same as "exists
but did not match" cases. The logic now executes both when the join
column doesn't exist and when it exists but doesn't match, ensuring rows
without join columns are preserved. If the join column is not defined at
all, the previous behavior remains unchanged.
Example:
```
For the tables:
let left_side = [{a: a1 ref: 1} {a: a2 ref: 2} {a: a3}]
let right_side = [[b ref]; [b1 1] [b2 2] [b3 3]]
Running "$left_side | join -l $right_side ref" now outputs:
╭───┬────┬─────┬────╮
│ # │ a │ ref │ b │
├───┼────┼─────┼────┤
│ 0 │ a1 │ 1 │ b1 │
│ 1 │ a2 │ 2 │ b2 │
│ 2 │ a3 │ │ │
╰───┴────┴─────┴────╯
```
# User-Facing Changes
The ```join``` command will behave more similarly to SQL-style joins. In
this case, rows that lack the join column are preserved.

Added 2 test cases.
fmt + clippy OK.

Closes#12858
# Description
As explained in the ticket, easy to reproduce. Example: 1.07 minute is
1.07*60=64.2 secondes
```nushell
# before - wrong
> 1.07min
1min 4sec
# now - right
> 1.07min
1min 4sec 200ms
```
# User-Facing Changes
Bug is fixed when using ``into duration``.

Closes #13972
# Description
First commit: a hotfix concerning my last PR #15544! I had a
``unwrap_or_default`` that resulted in all years before ~1800 being
considered as "now", because the ``num_nanoseconds()`` overflowed.
Cc @fdncred
Second: about #13972
Negative years are not allowed with RFC 2822 formatting, so I fallback
RTC 3339 in such cases.
If you want you might Rebase and Merge, and not squash.

Nothing required IMO
This addresses color issue; Yeees just got forgotten it :(
As far as I understand an acceptance test can't be created because ansi
got stripped in `nu!`. (for future regressions)
But wrapping I need to take a deeper look.

Issue #12289, can be closed when this is merged
# Description
Currently, the ``into datetime`` command's signature indicates that it
supports input as record, but it was actually not supported.
This PR implements this feature.

# User-Facing Changes
Certain errors no longer leave the argument stack in an unexpected
state:
```diff
let x: any = 1; try { $x | get path } catch { print caught }
-$.path # extra `print` argument from the failed `get` call
caught
```
# Description
If `eval_call` fails in `check_input_types` or `gather_arguments`, the
cleanup code is still executed.
We only have one valid `datetime` type, but the string representation of
that type was `date`. This PR updates the string representation of the
`datetime` type to be `datetime` and updates other affected
dependencies:
* A `describe` example that used `date`
* The style computer automatically recognized the new change, but also
changed the default `date: purple` to `datetime: purple`.
* Likewise, changed the `default_config.nu` to populate
`$env.config.color_config.datetime`
* Likewise, the dark and light themes in `std/config`
* Updates tests
* Unrelated, but changed the `into value` error messages to use
*"datetime"* if there's an issue.
Fixes#9916 and perhaps others.
## Breaking Changes:
* Code that expected `describe` to return a `date` will now return a
`datetime`
* User configs and themes that override `$env.config.color_config.date`
will need to be updated to use `datetime`
# Description
Closes#15351
Adds quotes that were missed in #14698 with the proper escaping.
# User-Facing Changes
`to nuon --serialize` will now produce a quoted string instead of
illegal nuon when given a closure
# Tests + Formatting
Reenable the `to nuon` rejection of closures in the base state test.
Added test for quoting.
# Description
Adds a new `--empty/-e` flag to the `default` command.
# User-Facing Changes
Before:
```nushell
$env.FOO = ""
$env.FOO = $env.FOO? | default bar
$env.FOO
# => Empty string
```
After:
```nushell
$env.FOO = ""
$env.FOO = $env.FOO? | default -e bar
$env.FOO
# => bar
```
* Uses `val.is_empty`, which means that empty lists and records are also
replaced
* Empty values in tables (with a column specifier) are also replaced.

Fixes issue #15135
Result
Also this works with other commands: min, max, sum, product, avg...
### User-Facing Changes
Error is returned, instead of console completely blocked and having to
be killed
I chose "Incorrect value", because commands accept inputs of range type,
just cannot work with unbounded ranges.

I didn't see the `save.rs::convert_to_extension` function tested
anywhere, but maybe I missed it.

This PR implements the changes proposed in #15112 without any breaking
changes. Should close#15112 post the review.
# Description
Added functionality to generate `uuid` versions 1, 3, 4, 5, 7 instead of
just the version 4.
- Users can now add a `-v n` flag to specify the version of uuid they
want to generate and it maintains backward compatibility by returning a
v4 uuid by default if no flags are passed.
- Versions 3 and 5 have the additional but required namespace (`-s`) and
name (`-n`) arguments too. Version 1 requires a mac address (`-m`).
# User-Facing Changes
- Added support for uuid versions 1, 3, 5 and 7.
- For v3 and v5, the namespace and name arguments are required and hence
there will be an error if those are not passed. Similarly the mac
address for v1.
- Full backward compatibility by setting v4 as default.

Fixes#14971, fixes#15229
# User-Facing Changes
Fixes a panic when variable data is accessed after invalid usage of the
`|` separator, which made it impossible to type certain match arms:
```nushell
> match $in { 1 |
Error: x Main thread panicked.
|-> at crates/nu-protocol/src/engine/state_delta.rs💯14
`-> internal error: missing required scope frame
```
# Description
Removes duplicative calls to `exit_scope` from an inner loop when `|`
parse errors are encountered. The outer loop creates and exits scopes
for each match arm.

Add ansi codes to move cursor position: `ansi cursor_left`, `ansi
cursor_right`, `ansi cursor_up`, `ansi cursor_down`
Why I add these? I'm trying to add a spinner to the message end for a
long running task, just to find that I need to move the cursor left to
make it work as expected: `with-progress 'Waiting for the task to
finish' { sleep 10sec }`
```nu
def with-progress [
message: string, # Message to display
action: closure, # Action to perform
--success: string, # Success message
--error: string # Error message
] {
print -n $'($message) '
# ASCII spinner frames
let frames = ['⠋', '⠙', '⠹', '⠸', '⠼', '⠴', '⠦', '⠧', '⠇', '⠏']
# Start the spinner in the background
let spinner_pid = job spawn {
mut i = 0
print -n (ansi cursor_off)
loop {
print -n (ansi cursor_left)
print -n ($frames | get $i)
sleep 100ms
$i = ($i + 1) mod ($frames | length)
}
}
# Run the action and capture result
let result = try {
do $action
{ success: true }
} catch {
{ success: false }
}
# Stop the spinner
job kill $spinner_pid
print "\r \r"
# Show appropriate message
if $result.success {
print ($success | default '✓ Done!')
} else {
print ($error | default '✗ Failed!')
exit 1
}
}

If a table contains an empty list or record in one column and both column
and -e flags are used, then skip that row.
`compact -e` now skips empty values in a column where as before they were
ignored. Example:
```nu
[["a", "b"]; ["c", "d"], ["h", []]]
| compact -e b
```
before
```plain
# a b
────────────────────────
0 c d
1 h [list 0 items]
```
after
```plain
# a b
───────────
0 c d
```
# Description
This is an attempt to improve the nushell situation with regard to issue
#247.
This PR implements:
- [X] spawning jobs: `job spawn { do_background_thing }`
Jobs will be implemented as threads and not forks, to maintain a
consistent behavior between unix and windows.
- [X] listing running jobs: `job list`
This should allow users to list what background tasks they currently
have running.
- [X] killing jobs: `job kill <id>`
- [X] interupting nushell code in the job's background thread
- [X] interrupting the job's currently-running process, if any.
Things that should be taken into consideration for implementation:
- [X] (unix-only) Handling `TSTP` signals while executing code and
turning the current program into a background job, and unfreezing them
in foreground `job unfreeze`.
- [X] Ensuring processes spawned by background jobs get distinct process
groups from the nushell shell itself
This PR originally aimed to implement some of the following, but it is
probably ideal to be left for another PR (scope creep)
- Disowning external process jobs (`job dispatch`)
- Inter job communication (`job send/recv`)
Roadblocks encountered so far:
- Nushell does some weird terminal sequence magics which make so that
when a background process or thread prints something to stderr and the
prompt is idle, the stderr output ends up showing up weirdly
