# Description
I've noticed that unlike everything else in nushell the output of `ansi
--list` has a column named `short name` instead of `short_name`, so I
changed it. While I was at it, I also added a shortname `rst` to `reset`
since it is often used.
# User-Facing Changes
Changed the column name of `ansi --list` from `short name` to
`short_name`
# Description
I have added a `--no-prefix` flag to the `format number` command to not
include the `0b`, `0x` and `0o` prefixes in the output. Also, I've
changed the order in which the formats are displayed to one I thinks
makes it easier to read, with the upper and lower alternatives next to
each other.
# User-Facing Changes
The formatting of floats previously did not include prefixes while
integers did. Now prefixes are on by default for both, while including
the new flag removes them. Changing the order of the record shouldn't
have any effect on previous code.
# Tests + Formatting
I have added an additional example that test this behavior.

Closes#15848. Currently, we expand unquoted strings to absolute paths
if they are of type `path` or `directory`. This PR makes this no longer
happen. `~`, `.`, and `..+` are still expanded, but a path like
`.../foo/bar/..` will only be turned into `../../foo`, rather than a
full absolute path.
This is mostly so that paths don't get modified before being sent to
known external commands (as in the linked issue). But also, it seems
unnecessary to make all unquoted paths absolute.
After feedback from @132ikl, this PR also makes it so that unquoted
paths are expanded at parse time, so that it matches the runtime
behavior. Previously, `path` expressions were turned into strings
verbatim, while `directory` expressions were treated as not being const.
API change: `nu_path::expansions::expand_path` is now exposed as
`nu_path::expand_path`.
# User-Facing Changes
This has the potential to silently break a lot of scripts. For example,
if someone has a command that expects an already-expanded absolute path,
changes the current working directory, and then passes the path
somewhere, they will now need to use `path expand` to expand the path
themselves before changing the current working directory.
# Tests + Formatting
Just added one test to make sure unquoted `path` arguments aren't made
absolute.
# After Submitting
This is a breaking change, so will need to be mentioned in the release
notes.
# Description
This PR makes the last specified CLI arguments take precedence over the
earlier ones.
Existing command line tools that align with the new behaviour include:
- `neovim`: `nvim -u a.lua -u b.lua` will use `b.lua`
- `ripgrep`: you can have `--smart-case` in your user config but
override it later with `--case-sensitive` or `--ignore-case` (not
exactly the same flag override as the one I'm talking about but I think
it's still a valid example of latter flags taking precedence over the
first ones)
I think a flag defined last can be considered an override. This allows
having a `nu` alias that includes some default config (`alias nu="nu
--config something.nu"`) but being able to override that default config
as if using `nu` normally.
## Example
```sh
nu --config config1.nu --config config2.nu -c '$nu.config-path'
```
The current behavior would print `config1.nu`, and the new one would
print `config2.nu`
## Implementation
Just `.rev()` the iterator to search for arguments starting from the end
of the list. To support that I had to modify the return type of
`named_iter` (I couldn't find a more generic way than
`DoubleEndedIterator`).
# User-Facing Changes
- Users passing repeated flags and relying in nushell using the first
value will experience breakage. Given that right now there's no point in
passing a flag multiple times I guess not many users will be affected
# Tests + Formatting
I added a test that checks the new behavior with `--config` and
`--env-config`. I'm happy to add more cases if needed

# Description
When attempting to pass a null byte in a commandline argument, Nu
currently fails with:
```
> ^echo (char -i 0)
Error: nu:🐚:io::invalid_input
× I/O error
╰─▶ × Could not spawn foreground child
╭────
1 │ crates/nu-command/src/system/run_external.rs:284:17
· ─────────────────────────┬─────────────────────────
· ╰── Invalid input parameter
╰────
```
This does not explain which input parameter is invalid, or why. Since Nu
does not typically seem to escape null bytes when printing values
containing them, this can make it a bit tricky to track down the
problem.
After this change, it fails with:
```
> ^echo (char -i 0)
Error: nu:🐚:io::invalid_input
× I/O error
╰─▶ × Could not spawn foreground child: nul byte found in provided data
╭────
1 │ crates/nu-command/src/system/run_external.rs:282:17
· ─────────────────────────┬─────────────────────────
· ╰── Invalid input parameter
╰────
```
which is more useful. This could be improved further but this is niche
enough that is probably not necessary.
This might make some other errors unnecessarily verbose but seems like
the better default. I did check that attempting to execute a
non-executable file still has a reasonable error: the error message for
that failure is not affected by this change.
It is still an "internal" error (referencing the Nu code triggering it,
not the user's input) because the `call.head` span available to this
code is for the command, not its arguments. Using it would result in
```
× I/O error
╰─▶ × Could not spawn foreground child: nul byte found in provided data
╭─[entry #1:1:2]
1 │ ^echo (char -i 0)
· ──┬─
· ╰── Invalid input parameter
╰────
```
which is actively misleading because "echo" does not contain the nul
byte.

# Description
Closes: #15755
I think it's a good feature, to achieve this, we need to get all hidden
envs(it's defined in `get_hidden_env_vars`, and then restore these envs
back to stack)
# User-Facing Changes
### Before
```nushell

### After
```nushell
> $env.foo = 'bar'
> overlay new xxx
> hide-env foo

```
## Note
But it doesn't work if it runs the example code in script:
`nu -c "$env.foo = 'bar'; overlay new xxx; hide-env foo; overlay hide
xxx; $env.foo"`
still raises an error says `foo` doesn't found. That's because if we run
the script at once, the envs in stack doesn't have a chance to merge
back into `engine_state`, which is only called in `repl`.
It introduces some sort of inconsistency, but I think users use overlays
mostly in repl, so it's good to have such feature first.

- improves rounding error reported in #15851
- my ~~discussion~~ monologue on how filesizes are parsed currently:
#15944
# Description
The issue linked above reported rounding errors when converting MiB to
GiB, which is mainly caused by parsing of the literal.
Nushell tries to convert all filesize values to bytes, but currently
does so in 2 steps:
- first converting it to the next smaller unit in `nu-parser` (so `MiB`
to `KiB`, in this case), and truncating to an `i64` here
- then converting that to bytes in `nu-engine`, again truncating to
`i64`
In the specific example above (`95307.27MiB`), this causes 419 bytes of
rounding error. By instead directly converting to bytes while parsing,
the value is accurate (truncating those 0.52 bytes, or 4.12 bits).
Rounding error in the conversion to GiB is also multiple magnitudes
lower.
(Note that I haven't thoroughly tested this, so I can't say with
confidence that all values would be parsed accurate to the byte.)
# User-Facing Changes
More accurate filesize values, and lower accumulated rounding error in
calculations.
# Tests + Formatting

Closes#14552
# Description
Implemented a new flag to the ```to md``` command to center specific
columns in Markdown table output using a list of CellPaths.
This enhances formatting control for users exporting tables to markdown.
## Example
For the table:
```shell
let t = version | select version build_time | transpose k v
```
```
╭───┬────────────┬────────────────────────────╮
│ # │ k │ v │
├───┼────────────┼────────────────────────────┤
│ 0 │ version │ 0.104.1 │
│ 1 │ build_time │ 2025-05-21 11:15:45 +01:00 │
╰───┴────────────┴────────────────────────────╯
```
Running ```$t | to md``` or ```$t | to md --pretty``` gives us,
respectively:
```
|k|v|
|-|-|
|version|0.104.1|
|build_time|2025-05-21 11:15:45 +01:00|
```
|k|v|
|-|-|
|version|0.104.1|
|build_time|2025-05-21 11:15:45 +01:00|
and
```
| k | v |
| ---------- | -------------------------- |
| version | 0.104.1 |
| build_time | 2025-05-21 11:15:45 +01:00 |
```
| k | v |
| ---------- | -------------------------- |
| version | 0.104.1 |
| build_time | 2025-05-21 11:15:45 +01:00 |
With the new ```center``` flag, when adding ```--center [v]``` to the
previous commands, we obtain, respectively:
```
|k|v|
|-|:-:|
|version|0.104.1|
|build_time|2025-05-21 11:15:45 +01:00|
```
|k|v|
|-|:-:|
|version|0.104.1|
|build_time|2025-05-21 11:15:45 +01:00|
and
```
| k | v |
| ---------- |:--------------------------:|
| version | 0.104.1 |
| build_time | 2025-05-21 11:15:45 +01:00 |
```
| k | v |
| ---------- |:--------------------------:|
| version | 0.104.1 |
| build_time | 2025-05-21 11:15:45 +01:00 |
The new ```center``` option, as demonstrated in the example, not only
formats the Markdown table to center columns but also, when paired with
```pretty```, it also centers the string values within those columns.
The logic works by extracting the column from the CellPath and applying
centering. So, ```--center [1.v]``` is also valid and centers the
```v``` column.
You can also specify multiple columns, for instance, ```--center [v
k]``` will center both columns in the example above.
# User-Facing Changes
The ```to md``` command will support column centering with the new
```center``` flag.
# Tests + Formatting
Added test cases to ensure correct behaviour.
fmt + clippy OK.
# After Submitting
The command documentation needs to be updated with the new ```center```
flag and an example.

# Description
Updates `help where` to better explain row conditions, and provide more
examples. Also, the syntax shape is changed to `one_of(condition,
closure())>`. I don't think this should affect parsing at all because it
should still always be parsed as `SyntaxShape::RowCondition`, but it
should be more clear that you can use a row condition _or_ a closure
here, even if technically we consider closures to be row conditions
internally. In a similar vein, the help text makes this distinction
explicitly to make it more clear to users that closures are supported.

- Updated the second @example for `find` to "Try to find an even

- Updated the second @example for `find-index` to "Try to find the index

I did a naive fix; which is probably all right.
But I want to spend some time to refactor a neighboring stuff.
And it's yet not to be released I guess;
I hope to add a few things beforehand.

**Title**: Better error handling for negative integer exponents in `**`
operator
---
### Bug Fix
This PR addresses an issue where attempting to raise an integer to a
negative power (e.g. `10 ** -1`) incorrectly triggered an
`OperatorOverflow` error. This behavior was misleading since the
overflow isn't actually the root problem — it's the unsupported
operation of raising integers to negative powers.
---
### Fix Summary
* Updated `Value::pow` to:
* Check for negative exponents when both operands are integers.
* Return a `ShellError::IncorrectValue` with a helpful message guiding
users to use floating point values instead.
#### Example:
```bash
> 10 ** -1
Error: nu:🐚:incorrect_value
× Incorrect value.
╝─[entry #2:1:4]
1 │ 10 ** -1
· ─┬┬
· │╰── encountered here
· ╰── Negative exponent for integer power is unsupported; use floats instead.
```
---
### Testing
Manual testing:
* `10 ** -1` → now returns a clear and appropriate `IncorrectValue`
error.
* `10.0 ** -1`, `10 ** -1.0`, etc. continue to work as expected.

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

When calling external commands, we convert our `$env` into a map where
each value is a string. If a value cannot be converted, it will be
skipped or when an `ENV_CONVERSION` is defined, will be converted via
that. This makes this conversion not that trivial. To ease debugging
this behavior or allowing to generate `.env` files from the current
environment did I add `debug env`.

# Description
This test has failed a number of times specifically on macOS. I'm not
exactly sure what the issue is, it seemed to work fine before. We should
probably actually fix it, but flaky CI is worse than missing this one

# Description
Following #15843, I have tinkered more with it and realized that there
are plenty of features from
[hyperfine](https://github.com/sharkdp/hyperfine) that could be
implemented pretty easily.
- `--warmup` flag to do `n` runs without benchmarking first, useful to
fill disk cache
```nu
@example "use --warmup to fill the disk cache before benchmarking" { bench { fd } { jwalk . -k } -w 1 -n 10 }
```
- `--setup`, `--prepare`, `--cleanup`, `--conclude` flags to run code
before/after benchmarks
```nu
@example "use `--setup` to compile before benchmarking" { bench { ./target/release/foo } --setup { cargo build --release } }
@example "use `--prepare` to benchmark rust compilation speed" { bench { cargo build --release } --prepare { cargo clean } }
```
- `--ignore-errors` to ignore any errors in the benchmarked commands
- benchmarked commands are now `| ignore` so that externals don't fill
the screen
## 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
---

This PR seeks to port the polars command `replace`
(https://docs.pola.rs/api/python/stable/reference/expressions/api/polars.Expr.replace.html)
and `replace_strict`
(https://docs.pola.rs/api/python/stable/reference/expressions/api/polars.Expr.replace_strict.html).
See examples below.
Consequently, the current `polars replace` and `polars replace-all` have
been renamed to `polars str-replace` and `polars str-replace-all` to
bring their naming better in-line with `polars str-join` and related str
commands.
```nushell
Usage:
> polars replace {flags} <old> (new)
Flags:
-h, --help: Display the help message for this command
-s, --strict: Require that all values must be replaced or throw an error (ignored if `old` or `new` are expressions).
-d, --default <any>: Set values that were not replaced to this value. If no default is specified, (default), an error is raised if any values were not replaced. Accepts expression input. Non-expression inputs are parsed as literals.
-t, --return-dtype <string>: Data type of the resulting expression. If set to `null` (default), the data type is determined automatically based on the other inputs.
Parameters:
old <one_of(record, list<any>)>: Values to be replaced
new <list<any>>: Values to replace by (optional)

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
**BREAKING CHANGE**: `polars replace` and `polars replace-all` have been
renamed to `polars str-replace` and `polars str-replace-all`.
The new `polars replace` now replaces elements in a series/column rather
than patterns within strings.

This PR involves two changes: (1) adding `maintain-order` flag to
`polars group-by` for stable sorting when aggregating and (2) allow
expression inputs in `polars filter`. The first change was necessary to
reliably test the second change, and the two commits are therefore
combined in one PR. See example:
```nushell
# Filter a single column in a group-by context
> [[a b]; [foo 1] [foo 2] [foo 3] [bar 2] [bar 3] [bar 4]] | polars into-df
| polars group-by a --maintain-order
| polars agg {
lt: (polars col b | polars filter ((polars col b) < 2) | polars sum)
gte: (polars col b | polars filter ((polars col b) >= 3) | polars sum)
}
| polars collect

- refactor `filter` to use `where` as its implementation
- replace usages of `filter` with `where` in `std`
# User-Facing Changes
- `get --sensitive` will raise a warning only once, during parsing
whereas before it was raised during runtime for each usage.
- using `filter` will raise a deprecation warning, once

Hello!
This is my 1st contribution and an attempt at fixing #15417.
# Description
When parsing a brace expression, check if the shape is a block or match
block before attempting to parse it as a closure.
Results:
- `if true {|| print hi}` now produces a `nu::parser` error instead of
executing and outputting `hi`. The `nu::parser` error is the same one
produced by running `|| print hi` (`nu::parser::shell_oror`)
- `match true {|| print hi}` now fails with a `nu::parser` error instead
of passing parsing and failing with `nu::compile::invalid_keyword_call`
My understanding reading the code/docs is that the shape is a contextual
constraint that needs to be satisfied for parsing to succeed, in this
case the `if` placing a `Block` shape constraint on next tokens. So it
would need to be checked in priority (if not `Any`) to understand how
the next tokens should be parsed. Is that correct? Or is there a reason
I'm not aware of to ignore the shape and attempt to parse as closure
like it's currently the case when the parser sees `|` or `||` as next
tokens?
# User-Facing Changes
No change in behaviour, but this PR fixes parsing to fail on some
incorrect syntax which could be considered a breaking change.
# Tests + Formatting
- Added corresponding tests
- `toolkit check pr` passed
Fixes#15788
# Description
Fixes null handling. Thanks to @MMesch for reporting and taking a first
stab at fixing.
