# Description
Fixes#15485
This PR changes pipeline checking to keep track of all possible output
types instead of only first type matching input type which appears in
the input/output types. For example, in this command:
```nushell
def foo []: [int -> string, int -> record] {
# ...
}
```
An `int` input to the command may result in a string or a record to be
output. Before this PR, Nushell would always assume that an `int` input
would cause a `string` output because it's the first matching
input/output type pair. This would cause issues during type checking
where the parser would incorrectly determine the output type. After this
PR, Nushell considers the command to output either a string or a record.
# User-Facing Changes

# Description
As title: this pr is try to introduce 2 functions to `PipelineData`:
1. PipelineData::list_stream --> create a PipelineData::ListStream
2. PipelineData::byte_stream -> create a PipelineData::ByteStream
And use these functions everywhere.
### Reason behind this change
I tried to implement `pipefail` feature, but this would required to
change `PipelineData` from enum to struct. So use these functions can
reduce diff if I finally change to struct. [Discord message

is my plan.

Using a custom `dialoguer::theme::Theme` implementation, how `input
list` renders items are overridden.
Unfortunately, implementing one of the methods requires
`fuzzy_matcher::skim::SkimMatcherV2` which `dialoguer` does not export
by itself.
Had to add an explicit dependency to `fuzzy_matcher`, which we already
depend on through `dialoguer`. Version specification is copied from
`dialoguer`.

Fix commit ID hex formatting in gstat, closes#16307
Leading zeros are preserved, maintaining the correct hex representation
This issue is relatively easy to fix, but it's not very easy to verify.
However, I have already tested several scenarios, it works for commit
sha like `000baeef`, `000003c7` and `00000002` etc.

# Description
## Problem
Parsing a multi span value as RowCondition always produces a RowCondition
expression that covers all the spans.
Which is problematic inside OneOf and can produce multiple expressions with
overlapping spans.
Which results in funky highlighting that duplicates text.
## Solution
Only reason for including `SyntaxShape::Closure` in the signature (#15697) was
for documentation purposes, making it clear in `help` texts that a closure can
be used as the argument.
As our current parser is shape directed, simplifying the command signature
means simplifies the parsing, so using a RowCondition on its own, and instead
making it always look like a union with `closure(any)` solves the issue without
any changes in the parser.
Also, RowCondition always accepts closure values anyway, so its textual
representation should indicate that without the need to wrap it in OneOf.

# Description
Fixes#15308. Surprisingly, I can't find any more issues that bring this
up.
This PR adds a check for interrupt before evaluating each IR
instruction. This makes it possible to ctrl-c out of things that were
difficult/impossible previously, like:
```nushell
loop {}
```
@devyn also [mentioned
previously](https://discord.com/channels/601130461678272522/615329862395101194/1268674828492083327)
that this might be a feasible option, but mentioned some performance
concerns.
I did some benchmarking previously but it turns out tango isn't the
greatest for this. I don't have hard numbers anymore but based on some
experimenting I shared in the Discord it seems like no experimental
option and limiting this to specific instructions should keep the
performance impact minimal.
<details>
<summary>Old benchmarking info</summary>
I did some benchmarks against main. It seems like most benchmarks are
between 1-6% slower, with some oddball exceptions.
The worst case seems to a giant loop, which makes sense since it's
mostly just jumping back to the beginning, meaning we hit the check over
and over again.
With `bench --pretty -n 100 { for i in 0..1000000 { 1 } }`, it seems
like the `ir-interrupt` branch is ~10% slower for this stress case:
```
main: 94ms 323µs 29ns +/- 1ms 291µs 759ns
ir-interrupt: 103ms 54µs 708ns +/- 1ms 606µs 571ns
(103ms + 54µs + 708ns) / (94ms + 323µs + 29ns) = 1.0925720801438639
```
The performance numbers here aren't great, but they're not terrible
either, and I think the usability improvement is probably worth it here.

# Description
I added a debug-only check that makes sure only non-other I/O errors get
converted.
Since tests run in debug mode, that should help us catch these errors early.
I left the check out in release mode on purpose so we don't crash users who
have nu as their main shell. It's similar to the debug assertions in the same
file that check for unknown spans.

# Description
Before this PR, errors without error codes are printed somewhat
strangely, with the `×` and the description being printed on the same
line as the `Error:` text:
Error: × Invalid literal
╭─[entry #1:1:2]
1 │ "\z"
· ─┬─
· ╰── unrecognized escape after '\' in string
╰────
This PR adds a default error code for the different error types:
Error: nu::parser::error
× Invalid literal
╭─[entry #1:1:2]
1 │ "\z"
· ─┬─
· ╰── unrecognized escape after '\' in string
╰────
While maybe not as informative as a proper error code, it makes
`GenericError`s and other things which don't have error codes look a lot
nicer.
It would be nicer if we could just set `diagnostic(code:
"nu:🐚:error")` at the top of `ShellError`, but unfortunately you
can't set a "default" at the `enum` level and then override it in the
variants. @cptpiepmatz mentioned he might change miette's derive macro
to accommodate this, in that case we can switch the approach here.
# User-Facing Changes
* Errors without error codes now have a default error code corresponding
to from which part of Nushell the error occurred (shell, parser,
compile, etc)

As decided on the team meeting on 2025-06-19, rename `--ignore-errors
(-i)` to `--optional (-o)` with a (currently) indefinite grace period.
After `--ignore-errors (-i)` is removed, the short flag `-i` can be used
for `--ignore-case` (not implemented as of this PR)
# User-Facing Changes
`get`/`select`/`reject`: rename `--ignore-errors (-i)` to `--optional
(-o)` to better reflect its behavior.

#16075
# Description
# User-Facing Changes
Improved experience: more meaningful items on top of the completion
menu.
Mostly for the fuzzy/substring matcher.
# Tests + Formatting

# After Submitting
# Description
Adds an `extern` definition (`KnownExternal`) for the `nu` command. This
way you can do `help nu` and get tab completions for flags on the `nu`
executable
# User-Facing Changes
* You can now view the flags for Nushell itself with `help nu`, and tab
completion for flags on `nu` works
# Description
Partially handles #14799
It's difficult to fix all cases there, but I think it's good to improve
one of this with a small step
# User-Facing Changes
Given the following code in c:
```C
// write.c
#include <stdio.h>
int main() {
while (1) {
printf("a\n");
}
}
```
After this pr, `./write | 0` will exit immediately, in that case,
`./write` will receive `SIGPIPE` in unix. Before this pr, `./write | 0`
runs indefinitely.
-----------------------
Maybe it's easier to see what happened internally by the different
output of `view ir { ./write | 0 }` command.
### Before
```
# 2 registers, 6 instructions, 7 bytes of data
0: load-literal %1, glob-pattern("./write", no_expand = false)
1: push-positional %1
2: redirect-out null
3: call decl 135 "run-external", %0
4: load-literal %0, int(0)
5: return %0
```
### After
```
# 2 registers, 6 instructions, 7 bytes of data
0: load-literal %1, glob-pattern("./write", no_expand = false)
1: push-positional %1
2: redirect-out pipe # changed, the command's output is a pipe rather than null
3: call decl 136 "run-external", %0
4: load-literal %0, int(0)
5: return %0
```

The setup in #16159 produced a `ByteStream` that held the `ShellError`
inside an `std::io::Error`. For exactly this setup is the
`ShellErrorBridge` designed, while figuring out what happened I found
out that inside `BytesStream::into_bytes` a sneaky `ShellErrorBridge`
was hiding:

src="https://github.com/user-attachments/assets/a0d16ca6-1a60-4c3c-a4cb-5e4b0695f20c"
/>
To fix this, I try to unwrap the bridge and if that is possible, return
the original `ShellError`. This is done at multiple occasions inside
`byte_stream.rs` already.
With this fix, we get the original error that looks like this:

<!--
Don't forget to add tests that cover your changes.
Make sure you've run and fixed any issues with these commands:
- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` to run the
tests for the standard library

To have less situations with other I/O errors, I opened #16160 to find
out faster what other error was passed around.

# Description
Unconditionally update the config state after each `overlay use` and
`overlay hide`.
The fix looks simple, but only because of the constant improvements and
refactors to the codebase that have taken place over time made it
possible.
Fixing these issue when they were initially filed would have been much
harder.
# User-Facing Changes
Overlays can add hooks, change color_config, update the config in
general.
# Tests + Formatting
No tests added as I still haven't figured out how to simulate the repl
in tests.

# Description
Cell-path accesses on `null` values throw an error, unless the initial
cell-path member is optional:
```nushell
">"; (null).a
# => Error: nu:🐚:incompatible_path_access
# =>
# => x Data cannot be accessed with a cell path
# => ,-[source:1:8]
# => 1 | (null).a
# => : |
# => : `-- nothing doesn't support cell paths
# => `----
">"; (null).a? | describe
# => nothing
```
`get` throws an error on `null` even when the cell-path is optional, and
only returns `null` quietly with the `--ignore-errors` flag
```nushell
">"; null | get a?
# => Error: nu:🐚:only_supports_this_input_type
# =>
# => x Input type not supported.
# => ,-[source:1:1]
# => 1 | null | get a?
# => : ^^|^ ^|^
# => : | `-- only table or record input data is supported
# => : `-- input type: nothing
# => `----
">"; null | get -i a? | describe
# => nothing

# 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:
