# Description
Changes miette warnings to use `Severity::Warning` instead of the
default `Severity::Error`. This shows them in a different color and with
a different icon:

src="https://github.com/user-attachments/assets/3ff0d3cf-ab1e-47f2-aff7-586ecea5a32a"
/>
# User-Facing Changes
* Warnings now look less like errors
these documentations say ">" when what they mean is ">>"
# Description
this documentation is about the use of ">>", but the documentation
wrongly says ">". it has been updated to say ">>" instead.
# User-Facing Changes
the user will see ">>" in the documentation instead of ">".
# Tests + Formatting
there is nothing to test. this is a documentation change.
# After Submitting
# Description
Conversion from `AnyType::DatetimeOwned` was missing, so datetime
objects could not be represented in Nushell Values. This adds the
conversion.
A slight refactor of the `datetime_from_epoch_nanos` was needed.
# User-Facing Changes
All datetime types can be represented in Nushell.
> Further tests are welcomed.
It was already implemented that we precalculate widths, but nothing
stops to do heights as well.
Because before all the calculus were wasted (literally).
It affects `table` and `table --expand`.
The only case when it does not work (even makes things slightly less
optimal in case of `table` when `truncation` is used)
Sadly my tests are not showing the clear benefit.
I have no idea why I was expecting something 😞
But it must be there :)
Running `scope commands` + `$env.CMD_DURATION_MS`:
```log
# patch (release)
2355 2462 2210 2356 2303
# main (release)
2375 2240 2202 2297 2385
```
PS: as once mentioned all this stuff ought to be moved out `nu-table`

Rel: #14429, #16079
Finishes up a TODO in the assignment type checking.
- For regular assignment operations (only applies to `mut`), type
checking is now done using `type_compatible` (which is what `let` uses)
- This allows some mutable assignments to work which weren't allowed
before
Before:
```nushell
let x: glob = ""
# => ok, no error
mut x: glob = ""; $x = ""
# => Error: nu::parser::operator_incompatible_types
# =>
# => × Types 'glob' and 'string' are not compatible for the '=' operator.
# => ╭─[entry #6:1:19]
# => 1 │ mut x: glob = ""; $x = ""
# => · ─┬ ┬ ─┬
# => · │ │ ╰── string
# => · │ ╰── does not operate between 'glob' and 'string'
# => · ╰── glob
# => ╰────
let x: number = 1
# ok, no error
mut x: number = 1; $x = 2
# => Error: nu::parser::operator_incompatible_types
# =>
# => × Types 'number' and 'int' are not compatible for the '=' operator.
# => ╭─[source:1:20]
# => 1 │ mut x: number = 1; $x = 2
# => · ─┬ ┬ ┬
# => · │ │ ╰── int
# => · │ ╰── does not operate between 'number' and 'int'
# => · ╰── number
# => ╰────
```
After:
```nushell
let x: glob = ""
# ok, no error (same as before)
mut x: glob = ""; $x = ""
# ok, no error
let x: number = 1
# ok, no error (same as before)
mut x: number = 1; $x = 2
# ok, no error
```
- Properly type check compound operations. First checks if the operation
(eg. `+` for `+=`) type checks successfully, and then checks if the
assignment type checks successfully (also using `type_compatible`)
- This fixes some issues where the "long version" of a compound
assignment operator would error, but the compound assignment operator
itself would not
Before:
```nushell

```
This is technically a breaking change if you relied on the old behavior
(for example, there was a test that broke after this change because it
relied on `/=` improperly type checking)
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
* Mutable assignment operations now use the same type checking rules as
normal assignments
* For example, `$x = 123` now uses the same type checking rules as `let
x = 123` or `mut x = 123`
* Compound assignment operations now type check using the same rules as
the operation they use
* Assignment errors will also now highlight the invalid assignment
operator in red

In #16028 I also added a test to check that identifiers are valid to
ensure that we have consistency there. But I only checked for
alphanumeric strings as identifiers. It doesn't allow underscores or
dashes. @Bahex used in his PR about #15682 a dash to separate words. So
expanded the test to allow that.

# Description
This PR makes the span of a pipeline accessible through `metadata`,
meaning it's possible to get the span of a pipeline without collecting
it.
Examples:
```nushell
ls | metadata
# => ╭────────┬────────────────────╮
# => │ │ ╭───────┬────────╮ │
# => │ span │ │ start │ 170218 │ │
# => │ │ │ end │ 170220 │ │
# => │ │ ╰───────┴────────╯ │
# => │ source │ ls │
# => ╰────────┴────────────────────╯
```
```nushell
ls | metadata access {|meta|
error make {msg: "error", label: {text: "here", span: $meta.span}}
}
# => Error: × error
# => ╭─[entry #7:1:1]
# => 1 │ ls | metadata access {|meta|
# => · ─┬
# => · ╰── here
# => 2 │ error make {msg: "error", label: {text: "here", span: $meta.span}}
# => ╰────
```
Here's an example that wouldn't be possible before, since you would have
to use `metadata $in` to get the span, collecting the (infinite) stream
```nushell
generate {|x=0| {out: 0, next: 0} } | metadata access {|meta|
# do whatever with stream
error make {msg: "error", label: {text: "here", span: $meta.span}}
}
# => Error: × error
# => ╭─[entry #16:1:1]
# => 1 │ generate {|x=0| {out: 0, next: 0} } | metadata access {|meta|
# => · ────┬───
# => · ╰── here
# => 2 │ # do whatever with stream
# => ╰────
```
I haven't done the tests or anything yet since I'm not sure how we feel
about having this as part of the normal metadata, rather than a new
command like `metadata span` or something. We could also have a
`metadata access` like functionality for that with an optional closure
argument potentially.

- Hooks' environment was not preserved prior to #5982 >
[2309601](2309601dd4/crates/nu-cli/src/repl.rs (L823-L840))

afterwards in #6355 >
[ea8b0e8](ea8b0e8a1d/crates/nu-engine/src/eval.rs (L174-L190))
Simply using `nu_engine::eval::redirect_env` for the environment update
was enough to fix the issue.

# Description
Adds formatting for code in backticks in `help` output. If it's possible
to highlight syntax (`nu-highlight` is available and there's no invalid
syntax) then it's highlighted. If the syntax is invalid or not an
internal command, then it's dimmed and italicized. like some of the
output from `std/help`. If `use_ansi_coloring` is `false`, then we leave
the backticks alone. Here's a couple examples:
(note on this one: usually we can highlight partial commands, like `get`
in the `select` help page which is invalid according to `nu-check` but
is still properly highlighted, however `where` is special cased and just
typing `where` with no row condition is highlighted with the garbage
style so `where` alone isn't highlighted here)
here's the `where` page with `$env.config.use_ansi_coloring = false`:
Technically, some syntax is valid but isn't really "Nushell code". For
example, the `select` help page has a line that says "Select just the
\`name\` column". If you just type `name` in the REPL, Nushell treats it
as an external command, but for the purposes of highlighted we actually
want this to fall back to the generic dimmed/italic style. This is
accomplished by temporarily setting the `shape_external` and
`shape_externalarg` color config to the generic/fallback style, and then
restoring the color config after highlighting. This is a bit hack-ish
but it seems to work pretty well.
# User-Facing Changes
- `help` command now supports code backtick formatting. Code will be
highlighted using `nu-highlight` if possible, otherwise it will fall
back to a generic format.
- Adds `--reject-garbage` flag to `nu-highlight` which will return an
error on invalid syntax (which would otherwise be highlighted with
`$env.config.color_config.shape_garbage`)
# Tests + Formatting
Added tests for the regex. I don't think tests for the actual
highlighting are very necessary since the failure mode is graceful and
it would be difficult to meaningfully test.

# User-Facing Changes
`start` now treats the input path differently. This is a breaking
change, I believe. Although I'm not sure how breaking it would be in the
perspective of the user.
# Tests + Formatting
I've manually tested this. The test suite for `start` is broken. And
even if I fix it, I'm not sure how to test it.
I'll need to override the default command list for `start` in the
sandbox for testing.
# After Submitting
I don't think the documentation needs to be updated.

This PR adds the `only` command to `std-rfc/iter`, which is a command I
wrote a while ago that I've found so useful that I think it could have a
place in the standard library. It acts similarly to `get 0`, but ensures
that the value actually exists, and there aren't additional values. I
find this most useful when chained with `where`, when you want to be
certain that no additional elements are accidentally selected when you
only mean to get a single element.
I'll copy the help page here for additional explanation:
> Get the only element of a list or table, ensuring it exists and there
are no extra elements.
>
> Similar to `first` with no arguments, but errors if there are no
additional
> items when there should only be one item. This can help avoid issues
when more
> than one row than expected matches some criteria.
>
> This command is useful when chained with `where` to ensure that only
one row
> meets the given condition.
>
> If a cell path is provided as an argument, it will be accessed after
the first
> element. For example, `only foo` is roughly equivalent to `get 0.foo`,
with
> the guarantee that there are no additional elements.
>
> Note that this command currently collects streams.
> Examples:
>
> Get the only item in a list, ensuring it exists and there's no
additional items
> ```nushell
> [5] | only
> # => 5
> ```
>
> Get the `name` column of the only row in a table
> ```nushell
> [{name: foo, id: 5}] | only name
> # => foo
> ```
>
> Get the modification time of the file named foo.txt
> ```nushell
> ls | where name == "foo.txt" | only modified
> ```
Here's some additional examples showing the errors:
Most of the time I chain this with a simple `where`, but here's a couple
other real world examples of how I've used this:
[With `parse`, which outputs a
table](https://git.ikl.sh/132ikl/dotfiles/src/branch/main/.scripts/manage-nu#L53):
```nushell
let commit = $selection | parse "{start}.g{commit}-{end}" | only commit
```
[Ensuring that only one row in a table has a name that ends with a
certain
suffix](https://git.ikl.sh/132ikl/dotfiles/src/branch/main/.scripts/btconnect):
```nushell
$devices | where ($chosen_name ends-with $it.name) | only
```
Unfortunately to get these nice errors I had to collect the stream (and
I think the errors are more useful for this). This should be to be
mitigated with (something like) #16014.
Putting this in `std/iter` might be pushing it, but it seems *just*
close enough that I can't really justify putting it in a different/new
module.

# Description
I wanted to know if `version` is a const command and thought that it
would be in the "This command" section but it wasn't, so I added it.
```
→ help version
Display Nu version, and its build configuration.
Category: core
This command:
Creates scope | ❌
Is built-in | ✅
Is const | ✅
Is a subcommand | ❌
Is a part of a plugin | ❌
Is a custom command | ❌
Is a keyword | ❌
```
# Description
Adding to #15962, I have realized that there are windows gui programs
like `prismlauncher` or `firefox` that do accept the `--help` flag but
won't output on the terminal unless `collect`ed, so now it collects the
output on windows.

## ✅ Improve `drop nth` command to support spreadable arguments
### Summary
This PR updates the `drop nth` command to support **spreadable
arguments** in a way consistent with other commands like `which`,
enabling:
```nu
[1 2 3 4 5] | drop nth 0 2 4
```
### What's Changed
* **Previously**: only a single index or a single range was accepted as
the first argument, with rest arguments ignored for ranges.
* **Now**: the command accepts any combination of:
* Integers: to drop individual rows
* Ranges: to drop slices of rows
* Unbounded ranges: like `3..`, to drop from index onward
Example:
```nu
[one two three four five six] | drop nth 0 2 4..5
# drops "one", "three", "five", and "six"
```
### Test
Manual Test:
### Notes
As per feedback:
* We **only collect the list of indices** to drop, not the input stream.
* Unbounded ranges are handled by terminating the stream early.
Let me know if you'd like further changes

Fixes the default behavior of #15790
# Description
As for the mentioned carapace version: `cat ~"/Downloads/Obsidian
Vault/"`, the problem lies in the unexpanded home directory `~`. Either
we encourage users to manually expand that in
`$env.config.completions.external.completer` or open an issue on the
carapace project.

# Description
Add 'double' table mode, that is similar to `compact_double` but with
left and right border lines. This is similar to how there exist both
`single` and `compact`, but there is no `double` to compliment
`compact_double`. Printing `[ { a: 1, b: 11 }, { a: 2, b:12 } ]` looks
like this:
```
╔═══╦═══╦════╗
║ # ║ a ║ b ║
╠═══╬═══╬════╣
║ 0 ║ 1 ║ 11 ║
║ 1 ║ 2 ║ 12 ║
╚═══╩═══╩════╝
```
The implementation is mostly a one-to-one of #15672 and #15681.
# User-Facing Changes
New value `double` to set as `$env.config.table.mode`.
# Tests + Formatting
Tests are added following the example of adding 'single' mode.
# After Submitting
# Description
fixes#16010
When `$env.LS_COLORS = 'fi=0' and `$env.config.color_config.string =
'red'` were set, regular files without file extensions would be colored
red. Now they're colored based on the LS_COLORS definition which, in
this case, means use default colors.
This is done by checking if a style was applied from ls_colors and if
none was applied, create a default nu_ansi_term style with
'Color::Default' for foreground and background.

Use hashset for existence checking.
Still needs a vector collection to keep the column order for tables.
# User-Facing Changes

# Description
I have just discovered the `std/help` command and that it can use `man`
or other programs for externals. Coming from windows, I don't have `man`
so what I want is just to run `external_program --help` in most cases.
This pr adds that option, if you set `$env.NU_HELPER = "--help"`, it
will run the command you passed with `--help` added as the last
argument.

This PR introduces a new switch for `query xml`, `--namespaces`,
and thus allows people to use namespace prefixes in the XPath query
to query namespaced XML.

Addresses #15997
Adds a `--backtrack` or `-b` named flag to the `parse` command. Allows a
user to specify a max backtrack limit for fancy-regex other than the
default 1,000,000 limit.
Uses a RegexBuilder to add the manual config.
