# Description
i was installing Nushell and, as we have the `dataframe` feature and
very soon at least the `extra` feature with more and more commands, i
thought it could be cool to have a little `toolkit install` command
😋
# User-Facing Changes
exposes the following command to developers
```
install Nushell and features you want
Usage:
> install ...(features)
Flags:
-h, --help - Display the help message for this command
Parameters:
...features <string>: a space-separated list of feature to install with Nushell

# Description
I noticed recently these timing discrepancies. I was thinking they would
be nearly identical but they were not.
```
> nu --no-std-lib -n -c "$nu.startup-time"
13ms 686µs 209ns
> nu --no-std-lib -n
> $nu.startup-time
2ms 520µs 416ns
```
My research showed that if `-n` was passed with `-c`, then the `-n` was
essentially being ignored. This PR corrects that.
Also worthy of understanding, if `nu -c "some command"` is passed, the
default env file is always loaded. I believe that's on purpose so that a
NU_LIB_DIRS env is available.
## After this PR (on a different system)
```
> nu --no-std-lib -n -c "$nu.startup-time"
6ms 688µs 600ns
> nu -n --no-std-lib
> $nu.startup-time
6ms 661µs 800ns
```

Fixes https://github.com/nushell/nushell/issues/9229.
Supersedes #9234
The reported problem was that `shells` list of active shells (a.k.a `std
dirs show` would show an inaccurate active
working directory if user changed it via `cd` command.
The fix here is for the `std dirs` module to let `$env.PWD` mask the
active slot of `$env.DIRS_LIST`. The user is free to invoke CD (or write
to `$env.PWD`) and `std dirs show` will display that as the active
working directory.
When user changes the active slot (via `n`, `p`, `add` or `drop`) `std
dirs` remembers the then current PWD in the about-to-be-vacated active
slot in `$env.DIRS_LIST`, so it is there if you come back to that slot.

I was trying `-H [key-A val-A] -H [key-B val-B]` but thanks to @Dorumin
I discovered how it should be used.
This PR just adds an extra example to the help with multiple headers.
Feel free to edit it either to merge both header examples into one or
rename the key value used, but I think it would be nice to have a sample
as the multiple -H variant doesn't error out it wasn't obvious to me.

# Description
i've almost always wanted to clean up the root of the repo, so here is
my take at it, with some important advice given by @fdncred 😌
- `README.release.txt` is now gone and directly inline in the
`release-pkg` script used in the `release` *workflow*
- `build.rs` has been moved to `scripts/` and its path has been changed
in
[`Cargo.toml`](https://github.com/amtoine/nushell/blob/refactor/clean-root/Cargo.toml#L3)
according to the [*Build Scripts*
section](https://doc.rust-lang.org/cargo/reference/build-scripts.html#build-scripts)
of *The Cargo Book*
- i've merged `images/` into `assets/` and fix the only mention to the
GIF in the README
- i've moved the `docs/README.md` inside the main `README.md` as a new
[*Configuration*
section](https://github.com/amtoine/nushell/tree/refactor/clean-root#configuration)
- the very deprecated `pkg_mgrs/` has been removed
- all the `.nu`, `.sh`, `.ps1` and `.cmd` scripts have been moved to
`scripts/`
### things i've left as-is
- all the other `.md` documents
- the configuration files
- all the Rust and core stuff
- `docker/`
- `toolkit.nu`
- the `wix/` diretory which appears to be important for `winget`
# User-Facing Changes
scripts that used to rely on the paths to some of the scripts should now
call the scripts inside `scripts/` => i think this for the greater good,
it was not pretty nor scalable to have a bunch of scripts in the root of
our main `nushell` 😱
*i even think we might want to move these scripts outside the main
`nushell` repo*
maybe to `nu_scripts` or some other tool 👍

All of the dataframe commands ported over with no issues...
### 11 tests are commented out (for now)
So 100 of the original 111 tests are passing with only 11 tests being
ignored for now..
As per our conversation in the core team meeting on Wednesday
I took @jntrnr suggestion and just commented out the tests dealing
with
[IntoDatetime](https://github.com/nushell/nushell/blob/main/crates/nu-command/src/conversions/into/mod.rs)
Later on we can move this functionality out of nu-command if we decide
it makes sense...

# Description
A new command to simplify assertions for `false`.
The name is just a draft, though I could not come up with a better name.
I have rejected `assert false`, because I would have to rename `assert`
to `assert true` which would break the compatibility and worsen the
shell experience of the good old `assert`.
Another idea I have rejected was something like `assert_false` to keep
it consistent with the naming convention of our stdlib.
I am open to suggestions :)

`ansi strip` (used in the clip command by default) removes tab symbols,
which is sometimes not useful (for example, when using the `[[a b]; [1
2]] | to tsv | clip` command). Therefore, I added a flag to prevent
using `ansi strip` in the clip command.

closes#9111
# Description
this pr improves parsing of values with units (`filesizes`, `durations`
and any other **future values**) by:
1. allowing underscores in the value part
```nu
> 42kb # okay
> 42_sec # okay
> 1_000_000mib # okay
> 69k_b # not okay, underscores not allowed in the unit
```
2. improving error messages involving these values
```nu
> sleep 40-sec
# before
Error: nu::parser::parse_mismatch
× Parse mismatch during operation.
╭─[entry #42:1:1]
1 │ sleep 40-sec
· ──┬──
· ╰── expected duration with valid units
╰────
# now
Error:
× duration value must be a number
╭─[entry #41:1:1]
1 │ sleep 40-sec
· ─┬─
· ╰── not a number
╰────
```
3. unifying parsing of these values. now all of these use one function
# User-Facing Changes
filesizes and durations can now have underscores for readability
# Description
Despite the innocent-looking title, this PR involves quite a few backend
changes as the existing LazyRecord trait was not at all friendly towards
the idea of these values being generated on the fly from Nu code.
In particular, here are a few changes involved:
- The LazyRecord trait now involves a lifetime `'a`, and this lifetime
is used in the return value of `get_column_names`. This means it no
longer returns `'static str`s (but implementations still can return
these). This is more stringent on the consumption side.
- The LazyRecord trait now must be able to clone itself via a new
`clone_value` method (as requiring `Clone` is not object safe). This
pattern is borrowed from `Value::CustomValue`.
- LazyRecord no longer requires being serde serializable and
deserializable.
These, in hand, allow for the following:
- LazyRecord can now clone itself, which means that they don't have to
be collected into a Record when being cloned.
- This is especially useful in Stack, which is cloned on each repl line
and in a few other cases. This would mean that _every_ LazyRecord
instance stored in a variable would be collected in its entirety and
cloned, which can be catastrophic for performance. See: `let nulol =
$nu`.
- LazyRecord's columns don't have to be static, they can have the same
lifetime of the struct itself, so different instances of the same
LazyRecord type can have different columns and values (like the new
`NuLazyRecord`)
- Serialization and deserialization are no longer meaningless, they are
simply less.
I would consider this PR very "drafty", but everything works. It
probably requires some cleanup and testing, though, but I'd like some
eyes and pointers first.
# User-Facing Changes
New command. New restrictions are largely internal. Maybe there are some
plugins affected?
Example of new command's usage:
```
lazy make --columns [a b c] --get-value { |name| print $"getting ($name)"; $name | str upcase }
```
You can also trivially implement something like `lazy make record` to
take a record of closures and turn it into a getter-like lazy struct:
```
def "lazy make record" [
record: record
] {
let columns = ($record | columns)
lazy make --columns $columns --get-value { |col| do ($record | get $col) }
}
```
Open to bikeshedding. `lazy make` is similar to `error make` which is
also in the core commands. I didn't like `make lazy` since it sounded
like some transformation was going on.
# Tour for reviewers
Take a look at LazyMake's examples. They have `None` as the results, as
such they aren't _really_ correct and aren't being tested at all. I
didn't do this because creating the Value::LazyRecord is a little tricky
and didn't want to risk messing it up, especially as the necessary
variables aren't available when creating the examples (like stack and
engine state).
Also take a look at NuLazyRecord's get_value implementation, or in
general. It uses an Arc<Mutex<_>> for the stack, which must be accessed
mutably for eval_block but get_value only provides us with a `&self`.
This is a sad state of affairs, but I don't know if there's a better
way.
On the same code path, we also have pipeline handling, and any pipeline
that isn't a Pipeline::Value will return Value::nothing. I believe
returning a Value::Error is probably better, or maybe some other
handling. Couldn't decide on which ShellError to settle with for that
branch.
The "unfortunate casualty" in the columns.rs file. I'm not sure just how
bad that is, though, I simply had to fight a little with the borrow
checker.
A few leftover comments like derives, comments about the now
non-existing serde requirements, and impls. I'll definitely get around
to those eventually but they're in atm
Should NuLazyRecord implement caching? I'm leaning heavily towards
**yes**, this was one of the main reasons not to use a record of
closures (besides convenience), but maybe it could be opt-out. I'd
wonder about its implementation too, but a simple way would be to move a
HashMap into the mutex state and keep cached values there.
Closes#9003.
This PR changes `group-by` so that its optional argument is interpreted
as a cell path. In turn, this lets users use `?` to ignore rows that are
missing the column they wish to group on. For example:
```
> [{foo: 123}, {foo: 234}, {bar: 345}] | group-by foo
Error: nu:🐚:column_not_found
× Cannot find column
╭─[entry #3:1:1]
1 │ [{foo: 123}, {foo: 234}, {bar: 345}] | group-by foo
· ─────┬──── ─┬─
· │ ╰── cannot find column 'foo'
· ╰── value originates here
╰────
> [{foo: 123}, {foo: 234}, {bar: 345}] | group-by foo?
╭─────┬───────────────╮
│ 123 │ [table 1 row] │
│ 234 │ [table 1 row] │
╰─────┴───────────────╯
```
~~This removes the ability to pass `group-by` a closure or block (I
wasn't able to figure out how to make the 2 features coexist), and so it
is a breaking change. I think this is OK; I didn't even know `group-by`
could accept a closure or block because there was no example for that
functionality.~~

# 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}
}
]
}

Related to #8368.
# Description
as planned in #8311, the `enter`, `shells`, `g`, `n` and `p` commands
have been re-implemented in pure-`nushell` in the standard library.
this PR removes the `rust` implementations of these commands.
- all the "shells" tests have been removed from
`crates/nu-commnand/tests/commands/` in
2cc6a82da6, except for the `exit` command
- `cd` does not use the `shells` feature in its source code anymore =>
that does not change its single-shell behaviour
- all the command implementations have been removed from
`crates/nu-command/src/shells/`, except for `exit.rs` => `mod.rs` has
been modified accordingly
- the `exit` command now does not compute any "shell" related things
- the `--now` option has been removed from `exit`, as it does not serve
any purpose without sub-shells
# User-Facing Changes
users may now not use `enter`, `shells`, `g`, `n` and `p`
now they would have to use the standard library to have access to
equivalent features, thanks to the `dirs.nu` module introduced by @bobhy
in #8368
# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- ⚫ `toolkit test`

along with dataframe tests
