# Description
Fixes#12382, where overlay changes from hooks were not preserved into
the global state. This was due to creating child stacks for hooks, when
the global stack should have been used instead.
# Description
This keeps plugin custom values that have requested drop notification
around during the lifetime of a plugin call / stream by sending them to
a channel that gets persisted during the lifetime of the call.
Before this change, it was very likely that the drop notification would
be sent before the plugin ever had a chance to handle the value it
received.
Tests have been added to make sure this works - see the `custom_values`
plugin.

# User-Facing Changes
This is basically just a bugfix, just a slightly big one.
However, I did add an `as_mut_any()` function for custom values, to
avoid having to clone them. This is a breaking change.
Some platforms don't support the `system-clipboard` feature, notably
termux on android.
The default config currently contained references to `reedline` events
that are only available with the feature enabled (#12179). This thus
broke the out of the box config for those users.
For now be more defensive about this and only enable default events. Add
the alternative as commented out code you can quickly enable.
## Tested with:
```
cargo run --no-default-features --features default-no-clipboard -- --config crates/nu-utils/src/sample_config/default_config.nu
```
- [x] `cargo hack` feature flag compatibility run
- [x] reedline released and pinned
- [x] `nu-plugin-test-support` added to release script
- [x] dependency tree checked
- [x] release notes
# Description
Fixes how the directory permissions are calculated in `mkdir`. Instead
of subtraction, the umask is actually used as a mask via negation
followed by bitwise and with the default mode. This matches how [uucore
calculates](cac7155fba/src/uu/mkdir/src/mkdir.rs (L61))
the mode.
# Description
This shrinks `Record`'s size in half and and allows you to include it in
`Value` without growing the size.
Changing the `Record` internals may have slightly different performance
characteristics as the cache locality changes on lookups (if you
directly need the value, it should be closer, but in other cases may
blow up the cache line budget)
Also different perf characteristics on creation expected.
`Record::from_raw_cols_vals` now probably worse.
## Benchmarking
Comparison with the main branch (boxed Record) revealed no significant
change to the creation but an improvement when accessing larger N.
The fact that this was more pronounced for nested access (still cloning
before nushell/nushell#12325) leads to the conclusion that this may
still be dominated by the smaller clone necessary for a 24-byte `Record`
over the previous 48 bytes.
# User-Facing Changes
Reduced memory usage
# Description
Currently `into bits` will try to coerce a `date`/`Value::Date` into a
string with a locale/timezone specific behavior (See #12268).
To resolve the ambiguity, remove the support for `date` entirely.
# User-Facing Changes
`date now | into bits` will now fail.
Instead you can use `... | format date '%c' | into bits` or any more
specific explicit choices to achieve the same behavior.
As `into bits` has minimal uses (and only pulled out of `extra` with
#12140), this doesn't warrant a deprecation.
# Description
Where possible, this PR replaces usages of raw `libc` bindings to
instead use safe interfaces from the `nix` crate. Where not possible,
the `libc` version reexported through `nix` was used instead of having a
separate `libc` dependency.
# Description
This changes the interface for plugins to always represent errors as
`LabeledError`s. This is good for altlang plugins, as it would suck for
them to have to implement and track `ShellError`. We save a lot of
generated code from the `ShellError` serde impl too, so `nu` and plugins
get to have a smaller binary size.
Reduces the release binary size by 1.2 MiB on my build configuration.
# User-Facing Changes
- Changes plugin protocol. `ShellError` no longer serialized.
- `ShellError` serialize output is different
- `ShellError` no longer deserializes to exactly the same value as
serialized

Those allocations are all small and insignificant in the grand scheme of
things and the optimizer may be able to resolve some of those but better
to be nice anyways.
Primarily inspired by the new
[`clippy::assigning_clones`](https://rust-lang.github.io/rust-clippy/master/index.html#/assigning_clones)
- **Avoid reallocs with `clone_from` in `nu-parser`**
- **Avoid realloc on assignment in `Stack`**
- **Fix `clippy::assigning_clones` in `nu-cli`**
- **Reuse allocations in `nu-explore` if possible**
# Description
This clone is not necessary and tanks the performance of deep nested
access.
As soon as we found the value, we know we discard the old value, so can
`std::mem::take` the inner (`impl Default for Value` to the rescue)
We may be able to further optimize this but not having to clone the
value is vital.
# Description
This pr is addressing feedback from
https://github.com/nushell/nushell/pull/12277#issuecomment-2027246752
Currently I think it's fine to replace `--legacy` flag with `--guess`
one. Only use `guess_width` algorithm if `--guess` is provided.
# User-Facing Changes
So it won't be a breaking change to previous version.
# Description
In #10232, the allowed input types were changed to be stricter, only
allowing records with types that can easily map onto sqlite equivalents.
Unfortunately, null was left out of the accepted input types, which
makes inserting rows with null values impossible.
This change fixes that by accepting null values as input.
One caveat of this is that when the command is creating a new table, it
uses the first row to infer an appropriate sqlite schema. If the first
row contains a null value, then it is impossible to tell which type this
column is supposed to have.
Throwing a hard error seems undesirable from a UX perspective, but
guessing can lead to a potentially useless database if we guess wrong.
So as a compromise, for null columns, we will assume the sqlite type is
TEXT and print a warning so the user knows. For the time being, if users
can't avoid a first row with null values, but also wants the right
schema, they are advised to create their table before running `into
sqlite`.
A future PR can add the ability to explicitly specify a schema.
Fixes#12225
# Tests + Formatting
* Tests added to cover expected behavior around insertion of null values

# Description
The second `Value` is redundant and will consume five extra bytes on
each transmission of a custom value to/from a plugin.
# User-Facing Changes
This is a breaking change to the plugin protocol.
The [example in the protocol
reference](https://www.nushell.sh/contributor-book/plugin_protocol_reference.html#value)
becomes
```json
{
"Custom": {
"val": {

"notify_on_drop": true
},
"span": {
"start": 320,
"end": 340
}
}
}
```
instead of
```json
{
"CustomValue": {
...
}
}
```
# After Submitting
Update plugin protocol reference
# Description
Now we only use `nix 0.28.0`
Achieved by
- updating `ctrlc` to `3.4.4`
- updating `wl-clipboard-rs` to `0.8.1`
- update our own dependency on `nix` from `0.27` to `0.28`
- required fixing uses of `nix::unistd::{tcgetpgrp,tcsetpgrp}`
- now requires an I/O safe file descriptor
- fake one pointing to `libc::STDIN_FILENO` (we were only accessing
`0` previously, dito for fish)
# User-Facing Changes
Better compile times and less to download as source dependencies
# Description
This is something that was discussed in the core team meeting last
Wednesday. @ayax79 is building `nu-plugin-polars` with all of the
dataframe commands into a plugin, and there are a lot of them, so it
would help to make the API more similar. At the same time, I think the
`Command` API is just better anyway. I don't think the difference is
justified, and the types for core commands have the benefit of requiring
less `.into()` because they often don't own their data
- Broke `signature()` up into `name()`, `usage()`, `extra_usage()`,
`search_terms()`, `examples()`
- `signature()` returns `nu_protocol::Signature`
- `examples()` returns `Vec<nu_protocol::Example>`
- `PluginSignature` and `PluginExample` no longer need to be used by
plugin developers
# User-Facing Changes
Breaking API for plugins yet again 😄

# Description
When implementing a `Command`, one must also import all the types
present in the function signatures for `Command`. This makes it so that
we often import the same set of types in each command implementation
file. E.g., something like this:
```rust
use nu_protocol::ast::Call;
use nu_protocol::engine::{Command, EngineState, Stack};
use nu_protocol::{
record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, PipelineData,
ShellError, Signature, Span, Type, Value,
};
```
This PR adds the `nu_engine::command_prelude` module which contains the
necessary and commonly used types to implement a `Command`:
```rust
// command_prelude.rs
pub use crate::CallExt;
pub use nu_protocol::{
ast::{Call, CellPath},
engine::{Command, EngineState, Stack},
record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, IntoSpanned,
PipelineData, Record, ShellError, Signature, Span, Spanned, SyntaxShape, Type, Value,
};
```
This should reduce the boilerplate needed to implement a command and
also gives us a place to track the breadth of the `Command` API. I tried
to be conservative with what went into the prelude modules, since it
might be hard/annoying to remove items from the prelude in the future.
Let me know if something should be included or excluded.

# Description
Binary values passed to `table` may or may not be pretty formatted based
on the output destination. This leads to weird behavior as documented in
#12287. This PR changes `table` to always pretty print binary values.
However, binary values passed to external commands will not be formatted
(this is the existing behavior).
# User-Facing Changes
This is a breaking change. E.g.:
```nushell
0x[8989] | table | cat -
```
used to print raw bytes, but it will now print the pretty formatted
bytes.
# After Submitting
Add to 0.92.0 release notes and update documentation.
Tables are the most common "large" data structures Nushell itself
creates. Benchmarking them and their common operations are central
- Creation via the explicit `[[]; [] []]` literal syntax
- `get` Access (`math sum` to guarantee consumption)
- `select` Slicing by columns
Currently low column count and high row count as the default example.
Future benchmarks should diversify this and provide tables with
irregular column order/presence (as this is currently allowed but rare
and requires extra bookkeeping in different commands)
# Description
Closes https://github.com/nushell/nushell/issues/12257
This was down to the use of `eval_block` instead of
`eval_block_with_early_return`. We may want to reconsider how we
differentiate between this behavior. We currently need to check all the
remaining commands that can invoke a closure block, if they properly
handle `ShellError::Return` as a passing of a `Value`
- **Add test for `return` in `filter` closure**
- **Fix use of `return` in `filter` closure**
# User-Facing Changes
You can now return a value from a `filter` closure

# Description
@fdncred found another histogram based algorithm to detect columns, and
rewrite it in rust: https://github.com/fdncred/guess-width
I have tested it manually, and it works good with `df`, `docker ps`,
`^ps`. This pr is going to use the algorithm in `detect columns`
Fix: #4183
The pitfall of new algorithm:
1. it may not works well if there isn't too much rows of input
2. it may not works well if the length of value is less than the header
to value, e.g:
```
c1 c2 c3 c4 c5
a b c d e
g h i j k
g a a q d
a v c q q | detect columns
```
In this case, users might need to use ~~`--old`~~ `--legacy` to make it
works well.
# User-Facing Changes
User might need to add ~~`--old`~~ `--legacy` to scripts if they find
`detect columns` in their scripts broken.

# Description
Uses the new `nu-plugin-test-support` crate to test the examples of
commands provided by plugins in the repo.
Also fixed some of the examples to pass.
# User-Facing Changes
- Examples that are more guaranteed to work
# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`
Fixes#12280.
# Description
This removes the dependency on the `difference` crate, which is
unmaintained, for `nu-plugin-test-support`. The `similar` crate
(Apache-2.0) is used instead, which is a bit larger and more complex,
but still suitable for a dev dep for tests. Also switched to use
`crossterm` for colors, since `similar` doesn't come with any terminal
pretty printing functionality.
# User-Facing Changes
None - output should be identical.
# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`
# Description
Cleanup search terms and help usage to be consistent and include
coreutils so people can easily find out which commands are coreutils.
