# Description
The meaning of the word usage is specific to describing how a command
function is *used* and not a synonym for general description. Usage can
be used to describe the SYNOPSIS or EXAMPLES sections of a man page
where the permitted argument combinations are shown or example *uses*
are given.
Let's not confuse people and call it what it is a description.
Our `help` command already creates its own *Usage* section based on the
available arguments and doesn't refer to the description with usage.
# User-Facing Changes
`help commands` and `scope commands` will now use `description` or
`extra_description`
`usage`-> `description`
`extra_usage` -> `extra_description`
Breaking change in the plugin protocol:
In the signature record communicated with the engine.
`usage`-> `description`
`extra_usage` -> `extra_description`
The same rename also takes place for the methods on
`SimplePluginCommand` and `PluginCommand`
# Tests + Formatting

# After Submitting

# Description
Prefer process name over executable path. This in practice causes the
`name` column to use just the base executable name.
Also set start_time to nothing on error, because why not.

# Description
This PR introduces a new `Signals` struct to replace our adhoc passing
around of `ctrlc: Option<Arc<AtomicBool>>`. Doing so has a few benefits:
- We can better enforce when/where resetting or triggering an interrupt
is allowed.
- Consolidates `nu_utils::ctrl_c::was_pressed` and other ad-hoc
re-implementations into a single place: `Signals::check`.
- This allows us to add other types of signals later if we want. E.g.,
exiting or suspension.
- Similarly, we can more easily change the underlying implementation if
we need to in the future.
- Places that used to have a `ctrlc` of `None` now use
`Signals::empty()`, so we can double check these usages for correctness
in the future.
# Description
I feel like it's a little sad that BSDs get to enjoy almost everything
other than the `ps` command, and there are some tests that rely on this
command, so I figured it would be fun to patch that and make it work.
The different BSDs have diverged from each other somewhat, but generally
have a similar enough API for reading process information via
`sysctl()`, with some slightly different args.
This supports FreeBSD with the `freebsd` module, and NetBSD and OpenBSD
with the `netbsd` module. OpenBSD is a fork of NetBSD and the interface
has some minor differences but many things are the same.
I had wanted to try to support DragonFlyBSD too, but their Rust version
in the latest release is only 1.72.0, which is too old for me to want to
try to compile rustc up to 1.77.2... but I will revisit this whenever
they do update it. Dragonfly is a fork of FreeBSD, so it's likely to be
more or less the same - I just don't want to enable it without testing
it.
Fixes#6862 (partially, we probably won't be adding `zfs list`)
# User-Facing Changes
`ps` added for FreeBSD, NetBSD, and OpenBSD.
# Tests + Formatting
The CI doesn't run tests for BSDs, so I'm not entirely sure if
everything was already passing before. (Frankly, it's unlikely.) But
nothing appears to be broken.
# After Submitting
- [ ] release notes?
- [ ] DragonflyBSD, whenever they do update Rust to something close
enough for me to try it
# Description
Does some misc changes to `ListStream`:
- Moves it into its own module/file separate from `RawStream`.
- `ListStream`s now have an associated `Span`.
- This required changes to `ListStreamInfo` in `nu-plugin`. Note sure if
this is a breaking change for the plugin protocol.
- Hides the internals of `ListStream` but also adds a few more methods.
- This includes two functions to more easily alter a stream (these take
a `ListStream` and return a `ListStream` instead of having to go through
the whole `into_pipeline_data(..)` route).
- `map`: takes a `FnMut(Value) -> Value`
- `modify`: takes a function to modify the inner stream.
# Description
Continuing from #12568, this PR further reduces the size of `Expr` from
64 to 40 bytes. It also reduces `Expression` from 128 to 96 bytes and
`Type` from 32 to 24 bytes.
This was accomplished by:
- for `Expr` with multiple fields (e.g., `Expr::Thing(A, B, C)`),
merging the fields into new AST struct types and then boxing this struct
(e.g. `Expr::Thing(Box<ABC>)`).
- replacing `Vec<T>` with `Box<[T]>` in multiple places. `Expr`s and
`Expression`s should rarely be mutated, if at all, so this optimization
makes sense.
By reducing the size of these types, I didn't notice a large performance
improvement (at least compared to #12568). But this PR does reduce the
memory usage of nushell. My config is somewhat light so I only noticed a
difference of 1.4MiB (38.9MiB vs 37.5MiB).

# 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
nushell is verified to work on FreeBSD 14 with these patches.
What isn't supported on FreeBSD:
* the crate 'procfs' doesn't support FreeBSD yet, all functionality
depending on procfs is disabled
* several RLIMIT_* values aren't supported on FreeBSD - functions
related to these are disabled

# Description
Replace `.to_string()` used in `GenericError` with `.into()` as
`.into()` seems more popular
Replace `Vec::new()` used in `GenericError` with `vec![]` as `vec![]`
seems more popular
(There are so, so many)
Fix the breaking changes.
Get's rid of some outdated transitive dependencies.
Sadly we need to expose more of `procfs` to `nu-command` based on how
the features of `nu-system` are exposed right now.
Conditional compilation/dependencies from hell included
Supersedes #11101
# Description
This PR tried to add a few more columns to the Linux `ps -l` command.
Those columns are:
* start_time
* user_id
* priority
* process_threads
There are a few that I left commented out that could be added but the
screen was beginning to look crowded. So, I left out:
* group_id
* session_id
* tgp_id (which could be helpful for eventual job control)
And there's like 100 more things that could be added that didn't seem
especially useful right now.

# Description
This PR creates a new `Record` type to reduce duplicate code and
possibly bugs as well. (This is an edited version of #9648.)
- `Record` implements `FromIterator` and `IntoIterator` and so can be
iterated over or collected into. For example, this helps with
conversions to and from (hash)maps. (Also, no more
`cols.iter().zip(vals)`!)
- `Record` has a `push(col, val)` function to help insure that the
number of columns is equal to the number of values. I caught a few
potential bugs thanks to this (e.g. in the `ls` command).
- Finally, this PR also adds a `record!` macro that helps simplify
record creation. It is used like so:
```rust
record! {
"key1" => some_value,
"key2" => Value::string("text", span),
"key3" => Value::int(optional_int.unwrap_or(0), span),
"key4" => Value::bool(config.setting, span),
}
```
Since macros hinder formatting, etc., the right hand side values should
be relatively short and sweet like the examples above.
Where possible, prefer `record!` or `.collect()` on an iterator instead
of multiple `Record::push`s, since the first two automatically set the
record capacity and do less work overall.
# User-Facing Changes
