# Description
before 0.83.0, `print` used to allow piping data into it, e.g.
```nushell
"foo" | print
```
instead of
```nushell
print "foo"
```
this PR enables the `any -> nothing` input / output type to allow this
again.
i've double checked and `print` is essentially the following snippet
```rust
if !args.is_empty() {
for arg in args {
arg.into_pipeline_data()
.print(engine_state, stack, no_newline, to_stderr)?;
}
} else if !input.is_nothing() {
input.print(engine_state, stack, no_newline, to_stderr)?;
}
```
1. the first part is for `print a b c`
2. the second part is for `"foo" | print`
# User-Facing Changes
```nushell
"foo" | print
```
works again

# Description
This PR ensures functions exist to extract and create each and every
`Value` case. It also renames `Value::boolean` to `Value::bool` to match
`Value::test_bool`, `Value::as_bool`, and `Value::Bool`. Similarly,
`Value::as_integer` was renamed to `Value::as_int` to be consistent with
`Value::int`, `Value::test_int`, and `Value::Int`. These two renames can
be undone if necessary.
# User-Facing Changes
No user facing changes, but two public functions were renamed which may
affect downstream dependents.
# Description
This PR fixes some problems I found in scripts by adding some additional
input_output_types.
Here's a list of nushell scripts that it fixed. Look for `# broke here:`
below.
This PR fixes 3, 4, 6, 7 by adding additional input_output_types. 1 was
fixed by changing the script. 2. just doesn't work anymore because mkdir
return type has changed. 5, is a problem with the script, the datatype
for `...rest` needed to be removed.
```nushell
# 1.
def terminal-size [] {
let sz = (input (ansi size) --bytes-until 'R')
# $sz should look like this
# Length: 9 (0x9) bytes | printable whitespace ascii_other non_ascii
# 00000000: 1b 5b 33 38 3b 31 35 30 52 •[38;150R
let sz_len = ($sz | bytes length)
# let's skip the esc[ and R
let r = ($sz | bytes at 2..($sz_len - 2) | into string)
# $r should look like 38;150
# broke here: because $r needed to be a string for split row
let size = ($r | split row ';')
# output in record syntax
{
rows: ($size | get 0)
columns: ($size | get 1)
}
}
# 2.
# make and cd to a folder

# Description
This PR removes the compile-time overload system. Unfortunately, this
system never worked correctly because in a gradual type system where
types can be `Any`, you don't have enough information to correctly
resolve function calls with overloads. These resolutions must be done at
runtime, if they're supported.
That said, there's a bit of work that needs to go into resolving
input/output types (here overloads do not execute separate commands, but
the same command and each overload explains how each output type
corresponds to input types).
This PR also removes the type scope, which would give incorrect answers
in cases where multiple subexpressions were used in a pipeline.
# User-Facing Changes
Finishes removing compile-time overloads. These were only used in a few
places in the code base, but it's possible it may impact user code. I'll
mark this as breaking change so we can review.

# Description
Until we bump our minimal Rust version to `1.70.0` we can't use
`std::io::IsTerminal`. The crate `is-terminal` (depending on `rustix` or
`windows-sys`) can provide the same.
Get's rid of the dependency on the outdated `atty` crate.
We already transitively depend on it (e.g. through `miette`)
As soon as we reach the new Rust version we can supersede this with

# Description
Fixes#9268, the issue was due to the fact that when `history_isolation`
was set to true the engine_state's `session_id` wasn't updated.
This PR mainly refactors the code that updates the line_editor's history
information into one function `update_line_editor_history` and also
updates the engine_state's `session_id` when `history_isolation` is set
to `true` by calling the function `store_history_id_in_engine`.

I tried to extract the block that was updating the line_editor's
`session_id` to make it easier to add a test.
The test checks that after a call to the function
`update_line_editor_history`, the `engine_state` and the returned
`line_editor` do have the same `session_id`.
# Description
We previously simply searched all commands in the working set. As our
deprecated/removed subcommands are documented by stub commands that
don't do anything apart from providing a message, they were still
included.
With this change we check the `Signature.category` to not be
`Category::Deprecated`.
## Note on performance
Making this change will exercise `Command.signature()` more
frequently! As the rust-implemented commands include their builders here
this probably will cause a number of extra allocations. There is
actually no valid reason why the commands should construct a new
`Signature` for each call to `Command.signature()`.
This will introduce some overhead to generate the completions for
commands.

This PR reverts https://github.com/nushell/nushell/pull/9391
We try not to revert PRs like this, though after discussion with the
Nushell team, we decided to revert this one.
The main reason is that Nushell, as a codebase, isn't ready for these
kinds of optimisations. It's in the part of the development cycle where
our main focus should be on improving the algorithms inside of Nushell
itself. Once we have matured our algorithms, then we can look for
opportunities to switch out technologies we're using for alternate
forms.
Much of Nushell still has lots of opportunities for tuning the codebase,
paying down technical debt, and making the codebase generally cleaner
and more robust. This should be the focus. Performance improvements
should flow out of that work.
Said another, optimisation that isn't part of tuning the codebase is
premature at this stage. We need to focus on doing the hard work of
making the engine, parser, etc better.

# Description
Make sure that our different crates that contain commands can be
compiled in parallel.
This can under certain circumstances accelerate the compilation with
sufficient multithreading available.
## Details
- Move `help` commands from `nu-cmd-lang` back to `nu-command`
- This also makes sense as the commands are implemented in an
ANSI-terminal specific way
- Make `nu-cmd-lang` only a dev dependency for `nu-command`
- Change context creation helpers for `nu-cmd-extra` and
`nu-cmd-dataframe` to have a consistent api used in
`src/main.rs`:`get_engine_state()`
- `nu-command` now indepedent from `nu-cmd-extra` and `nu-cmd-dataframe`
that are now dependencies of `nu` directly. (change to internal
features)
- Fix tests that previously used `nu-command::create_default_context()`
with replacement functions
## From scratch compilation times:
just debug (dev) build and default features
```
cargo clean --profile dev && cargo build --timings
```

# User-Facing Changes
None direct, only change to compilation on multithreaded jobs expected.
# Tests + Formatting
Tests that previously chose to use `nu-command` for their scope will
still use `nu-cmd-lang` + `nu-command` (command list in the granularity
at the time)
# Description
Makes use of the feature introduced by nushell/reedline#566
If we consider this to be problematic we can decide to add a config
point for this behavior, but at first I was a bit hesistant expanding
the config in this area.
# User-Facing Changes
Follows precedent found in bash/zsh/fish to exclude lines starting with
a space from the history.

# Description
Fixes: #8565
Here is another pr #7240 tried to address the issue, but it works in a
wrong way.
After this change `o+e>` won't redirect all stdout message then stderr
message and it works more like how bash does.
# User-Facing Changes
For the given python code:
```python
# test.py
import sys
print('aa'*300, flush=True)
print('bb'*999999, file=sys.stderr, flush=True)
print('cc'*300, flush=True)
```
Running `python test.py out+err> a.txt` shoudn't hang nushell, and
`a.txt` keeps output in the same order
## About the change
The core idea is that when doing lite-parsing, introduce a new variant
`LiteElement::SameTargetRedirection` if we meet `out+err>` redirection
token(which is generated by lex function),
During converting from lite block to block,
LiteElement::SameTargetRedirection will be converted to
PipelineElement::SameTargetRedirection.
Then in the block eval process, if we get
PipelineElement::SameTargetRedirection, we'll invoke `run-external` with
`--redirect-combine` flag, then pipe the result into save command
## What happened internally?
Take the following command as example:
`^ls o+e> log.txt`
lex parsing result(`Tokens`) are not changed, but `LiteBlock` and
`Block` is changed after this pr.
### LiteBlock before
```rust
LiteBlock {
block: [
LitePipeline { commands: [
Command(None, LiteCommand { comments: [], parts: [Span { start: 39041, end: 39044 }] }),
// actually the span of first Redirection is wrong too..
Redirection(Span { start: 39058, end: 39062 }, StdoutAndStderr, LiteCommand { comments: [], parts: [Span { start: 39050, end: 39057 }] }),
]
}]
}
```
### LiteBlock after
```rust
LiteBlock {
block: [
LitePipeline {
commands: [
SameTargetRedirection {
cmd: (None, LiteCommand { comments: [], parts: [Span { start: 147945, end: 147948}]}),
redirection: (Span { start: 147949, end: 147957 }, LiteCommand { comments: [], parts: [Span { start: 147958, end: 147965 }]})
}
]
}
]
}
```
### Block before
```rust
Pipeline {
elements: [
Expression(None, Expression {
expr: ExternalCall(Expression { expr: String("ls"), span: Span { start: 39042, end: 39044 }, ty: String, custom_completion: None }, [], false),
span: Span { start: 39041, end: 39044 },
ty: Any, custom_completion: None
}),
Redirection(Span { start: 39058, end: 39062 }, StdoutAndStderr, Expression { expr: String("out.txt"), span: Span { start: 39050, end: 39057 }, ty: String, custom_completion: None })] }
```
### Block after
```rust
Pipeline {
elements: [
SameTargetRedirection {
cmd: (None, Expression {
expr: ExternalCall(Expression { expr: String("ls"), span: Span { start: 147946, end: 147948 }, ty: String, custom_completion: None}, [], false),
span: Span { start: 147945, end: 147948},
ty: Any, custom_completion: None
}),
redirection: (Span { start: 147949, end: 147957}, Expression {expr: String("log.txt"), span: Span { start: 147958, end: 147965 },ty: String,custom_completion: None}

Show parameter defaults in scope command signature, where they're
available for display by help.
per https://github.com/nushell/nushell/issues/8928.
I found unexpected ramifications in one completer (NuHelpCompleter) and
plugins, which both use the flag-formatting routine from builtin help.
For the moment I made the minimum necessary changes to get the mainline
scenario to pass tests and run. But we should circle back on what to do
with plugins and help completer..
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
1. New `parameter_default` column to `signatures` table in
`$nu.scope.commands`
It is populated with whatever parameters can be defaulted: currently
positional args and named flags.
2. Built in help (both `help <command>` and `<command> --help` will
display the defaults
3. Help completer will display defaults for flags, but not for
positionals.
Example:
A custom command with some default parameters:
```
〉cat ~/work/dflts.nu
# sample function to show defaults in help
export def main [
arg1: string # mandatory positional
arg2:string=abc # optional positional
--switch # no default here
--named:int # named flag, no default
--other:string=def # flag
--hard:record<foo:int bar:string, bas:bool> # default can be compound type
= {foo:22, bar:"other worlds", bas:false}
] { {arg1: $arg1,
arg2: $arg2,
switch: $switch,
named: $named,
other: $other,
hard: $hard, }
}
〉use ~/work/dflts.nu
〉$nu.scope.commands | where name == 'dflts' | get signatures.0.any | reject short_flag description custom_completion

〉help dflts
sample function to show defaults in help
Usage:
> dflts {flags} <arg1> (arg2)
Flags:
--switch - switch -- no default here
--named <Int> - named flag, typed, but no default
--other <String> - flag with default (default: 'def')
--hard <Record([("foo", Int), ("bar", String), ("bas", Boolean)])> - default can be compound type (default: {foo: 22, bar: 'other worlds', bas: false})
-h, --help - Display the help message for this command
Parameters:
arg1 <string>: mandatory positional
arg2 <string>: optional positional (optional, default: 'abc')
```
Compared to (relevant bits of) help output previously:
```
Flags:
-h, --help - Display the help message for this command
-, --switch - no default here
-, --named <int> - named flag, no default
-, --other <string> - flag
-, --hard <record<foo: int, bar: string, bas: bool>> - default can be compound type
Signatures:
<any> | dflts <string> <string> -> <any>
Parameters:
arg1 <string>: mandatory positional
(optional) arg2 <string>: optional positional

- #8353
# Description
with the new `$nu.startup-time` from #8353 and as mentionned in #8311,
we are now able to fully move the `nushell` banner from the `rust`
source base to the standard library.
this PR
- removes all the `rust` source code for the banner
- rewrites a perfect clone of the banner to `std.nu`, called `std
banner`
- call `std banner` from `default_config.nu`
# User-Facing Changes
see the demo: https://asciinema.org/a/566521
- no config will show the banner (e.g. `cargo run --release --
--no-config-file`)
- a custom config without the `if $env.config.show_banner` block and no
call to `std banner` would never show the banner
- a custom config with the block and `config.show_banner = true` will
show the banner
- a custom config with the block and `config.show_banner = false` will
NOT show the banner
# Tests + Formatting
a new test line has been added to `tests.nu` to check the length of the
`std banner` output.

# Description
This PR impacts the nushell sqlite history only.
This is the first PR that enables history isolation in nushell for the
sqlite history. Hopefully, we can continue building on this.
This PR allows "history isolation" which means that other nushell
session's history won't be available in the current session when using
the uparrow/downarrow history navigation. This change only impacts the
uparrow downarrow history navigation.
What remains to be done is making ctrl+r history menu respect this
setting too. Right now, the history menu will still show you all entries
from all sessions.
The history command also shows all history items from all sessions. This
may remain unchanged since you can just filter by history session right
now.
This also fixes a bug where the session id is 0 in the sqlite history
since my April 18th reedline PR.
Closes#9064

Close: #8988
Thanks to new crossterm version, nushell can support blink cursor shape.
It can be config with the following value:
1. blink_block
2. blink_line
3. blink_underscore
And original block, line, underscore will be steady. It also fixes wrong
shape of `underscore`.
# User-Facing Changes
Here is a little breaking change, before the change: `line` cursor shape
is blinking line, but after this pr, it will be `steady line`. To make a
blink line, we need to change the value to `blink_line`.
But I think it's ok, because after the change, we have a good naming
convention about the name of shape

# Description
Part of the larger cratification effort.
Moves all `reedline` or shell line editor specific commands to `nu-cli`.
## From `nu-cmd-lang`:
- `commandline`
- This shouldn't have moved there. Doesn't directly depend on reedline
but assumes parts in the engine state that are specific to the use of
reedline or a REPL
## From `nu-command`:
- `keybindings` and subcommands
- `keybindings default`
- `keybindings list`
- `keybindings listen`
- very `reedline` specific
- `history`
- needs `reedline`
- `history session`
## internal use
Instead of having a separate `create_default_context()` that calls
`nu-command`'s `create_default_context()`, I added a `add_cli_context()`
that updates an `EngineState`
# User-Facing Changes
None
## Build time comparison
`cargo build --timings` from a `cargo clean --profile dev`
### total
main: 64 secs
this: 59 secs
### `nu-command` build time
branch | total| codegen | fraction
---|---|---|---
main | 14.0s | 6.2s | (44%)
this | 12.5s | 5.5s | (44%)
`nu-cli` depends on `nu-command` at the moment.
Thus it is built during the code-gen phase of `nu-command` (on 16
virtual cores)
# Tests + Formatting
I removed the `test_example()` facilities for now as we had not run any
of the commands in an `Example` test and importing the right context for
those tests seemed more of a hassle than the duplicated
`test_examples()` implementations in `nu-cmd-lang` and `nu-command`
# Description
We were seeing duplicate entries for the std lib files, and this PR
addresses that. Each file should now only be added once.
Note: they are still parsed twice because it's hard to recover the
module from the output of `parse` but a bit of clever hacking in a
future PR might be able to do that.

now nu_std only depends on nu_parser, nu_protocol and miette
and removes the nu_cli dependency
this enables developers moving forward to come along and implement their
own CLI's without having to pull in a redundant nu-cli which will not be
needed for them.
I did this by moving report_error into nu_protocol
which nu_std already has a dependency on anyway....

# Description
This is a pretty heavy refactor of the parser to support multiple parser
errors. It has a few issues we should address before landing:
- [x] In some cases, error quality has gotten worse `1 / "bob"` for
example
- [x] if/else isn't currently parsing correctly
- probably others

This may have error quality degradation as we adjust to the new error
reporting mechanism.

This adds a set of new flags on the `nu` binary intended for use in
IDEs. Here is the set of supported functionality so far:
* goto-def - go to the definition of a variable or custom command
* type hints - see the inferred type of variables
* check - see the errors in the document (currently only one error is
supported)
* hover - get information about the variable or custom command
* complete - get a completion list at the current position

Some minor code cleanup.
We've accumulated a few macros over the years that arguably don't need
to be macros. This PR removes 4 macros by either:
1. Inlining the macro
2. Replacing the macro with a local function
3. Replacing the macro with a closure
# Description
This adds `match` and basic pattern matching.
An example:
```
match $x {
1..10 => { print "Value is between 1 and 10" }
{ foo: $bar } => { print $"Value has a 'foo' field with value ($bar)" }
[$a, $b] => { print $"Value is a list with two items: ($a) and ($b)" }
_ => { print "Value is none of the above" }
}
```
Like the recent changes to `if` to allow it to be used as an expression,
`match` can also be used as an expression. This allows you to assign the
result to a variable, eg) `let xyz = match ...`
I've also included a short-hand pattern for matching records, as I think
it might help when doing a lot of record patterns: `{$foo}` which is
equivalent to `{foo: $foo}`.
There are still missing components, so consider this the first step in
full pattern matching support. Currently missing:
* Patterns for strings
* Or-patterns (like the `|` in Rust)
* Patterns for tables (unclear how we want to match a table, so it'll
need some design)
* Patterns for binary values
* And much more

# Description
This PR fixes a bug that prevented you from having multiple modifiers on
your keybindings.
TODO:
- The docs need to be fixed too
https://www.nushell.sh/book/line_editor.html#keybindings.
(https://github.com/nushell/nushell.github.io/pull/840)
- I think reedline needs to be changed to show this too since it
provides the list of available modifiers.
(https://github.com/nushell/reedline/pull/559)
Now you can do something like this where `shift` and `alt` are combined
with an underscore.
```
{
name: fuzzy_history_fzf
modifier: shift_alt
keycode: char_r
mode: [emacs , vi_normal, vi_insert]
event: {
blah
}
```
Here's the list of available combinations
```rust
"control" => KeyModifiers::CONTROL,
"shift" => KeyModifiers::SHIFT,

# Tests + Formatting
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 -A
clippy::needless_collect` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass
> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr

…ion` hook
# Description
Previously when a `executehostcommand` shortcut calls `commandline`, to
get the current command line, it's incorrectly set to the value of
`executehostcommand` `cmd`.
This fixes the regression (due to #8207), so it's correctly set to
what's in the REPL buffer.

# Description
Add a `command_not_found` function to `$env.config.hooks`. If this
function outputs a string, then it's included in the `help`.
An example hook on *Arch Linux*, to find packages that contain the
binary, looks like:
```nushell
let-env config = {
# ...
hooks: {
command_not_found: {
|cmd_name| (
try {
let pkgs = (pkgfile --binaries --verbose $cmd_name)
(
$"(ansi $env.config.color_config.shape_external)($cmd_name)(ansi reset) " +
$"may be found in the following packages:\n($pkgs)"
)
} catch {
null
}
)
}
# ...
```
# User-Facing Changes

Reverts nushell/nushell#8310
In anticipation that we may want to revert this PR. I'm starting the
process because of this issue.
This stopped working
```
let-env NU_LIB_DIRS = [
($nu.config-path | path dirname | path join 'scripts')
'C:\Users\username\source\repos\forks\nu_scripts'
($nu.config-path | path dirname)
]
```
You have to do this now instead.
```
const NU_LIB_DIRS = [
'C:\Users\username\AppData\Roaming\nushell\scripts'
'C:\Users\username\source\repos\forks\nu_scripts'
'C:\Users\username\AppData\Roaming\nushell'
]
```
In talking with @kubouch, he was saying that the `let-env` version
should keep working. Hopefully it's a small change.
