feat: allow from csv to accept 4 byte unicode separator chars (#10138)
- this PR should close #10132

# Description
* added a flag to `from csv --ascii` that replaces the given `separator
with the unicode separator x1f https://www.codetable.net/hex/1f (aka
Information Separator One)

# User-Facing Changes
New flags are available for `from csv` ( `--ascii` or short `-a`)

# Tests + Formatting
There are no tests at the moment. Code has been formatted.
- `cargo test --workspace` (breaks with a non related test on my
machine)

Spanned Value step 1: span all value cases (#10042)
# Description

This doesn't really do much that the user could see, but it helps get us
ready to do the steps of the refactor to split the span off of Value, so
that values can be spanless. This allows us to have top-level values
that can hold both a Value and a Span, without requiring that all values
have them.

We expect to see significant memory reduction by removing so many
unnecessary spans from values. For example, a table of 100,000 rows and
5 columns would have a savings of ~8megs in just spans that are almost
always duplicated.

remove --column from length command and remove record processing (#10091)
# Description

This PR removes `record` processing from the `length` command. It just
doesn't make sense to try and get the length of a record. This PR also
removes the `--column` parameter. If you want to list or count columns,
you could use `$table | columns` or `$table | columns | length`.

Make http -f display the request headers. Closes #9912 (#10022)
# Description
As described in https://github.com/nushell/nushell/issues/9912, the
`http` command could display the request headers with the `--full` flag,
which could help in debugging the requests. This PR adds such
functionality.

# User-Facing Changes
If `http get` or other `http` command which supports the `--full` flag
is invoked with the flag, it used to display the `headers` key which
contained an table of response headers. Now this key contains two nested
keys: `response` and `request`, each of them being a table of the
response and request headers accordingly.

Rename misused "deprecation" to removal (#10000)
# Description
In the past we named the process of completely removing a command and
providing a basic error message pointing to the new alternative
"deprecation".

But this doesn't match the expectation of most users that have seen
deprecation _warnings_ that alert to either impending removal or
discouraged use after a stability promise.

Currently `parse` acts like a `.filter` over an iterator, except that it
emits `None` for elements that can't be parsed. This causes consumers of
the adapted iterator to stop iterating too early. The correct behaviour
is to keep pulling the inner iterator until either the end of it is
reached or an element can be parsed.

- this PR should close #9906

Add an option to set header on border (style) (#9920)

Sorry that you've had the issues.
I've actually encountered them yesterday too (seems like they have
appeared after some refactoring in the middle) but was not able to fix
that rapid.

Created a bunch of tests.

cc: @fdncred 

Note:

This option will be certainly slower then a default ones. (could be
fixed but ... maybe later).
Maybe it shall be cited somewhere.

PS: Haven't tested on a wrapped/expanded tables.

Accept records for http subcommand headers (-H) (#9771)
# Description

See also: #9743 
Before: 
`http <subcommand> -H` took a list in the form:

```nushell
[my-header-key-A my-header-value-A my-header-key-B my-header-value-B]
```

Now:
In addition to the old format, Records can be passed, For example,
```nushell
> let reqHeaders = {
    Cookie:  "acc=barfoo",
    User-Agent: "Mozilla/7.0 (Windows NT 33.0; Win64; x64) AppleWebKit/1038.90 (KHTML, like Gecko)"
}
> http get -H $reqHeaders https://example.com
```

is now equivalent to
```nushell
http get -H [Cookie "acc=barfoo" User-Agent "Mozilla/7.0 (Windows NT 33.0; Win64; x64) AppleWebKit/1038.90 (KHTML, like Gecko)"] https://example.com
```

# User-Facing Changes

but it was a table.

add table -> table to into datetime (#9775)
should close https://github.com/nushell/nushell/issues/9774

# Description
given the help page of `into datetime`, 
```
Parameters:
  ...rest <cellpath>: for a data structure input, convert data at the given cell paths
```
it looks like `into datetime` should accept tables as input 🤔 

this PR
- adds the `table -> table` signature to `into datetime`
- adds a test to make sure the behaviour stays there

change the output of which to be more explicit (#9646)
related to
- https://github.com/nushell/nushell/issues/9637#issuecomment-1629387548

# Description
this PR changes the output of `which` from `table<arg: string, path:
string, built-in: bool> (stream)` to `table<command: string, path:
string, type: string> (stream)`.
- `command`: same as `arg` but more explicit name
- `path`: same as before, `null` when built-in
- `type`: instead of `buil-in: bool` says if it's a `built-in` a
`custom` command, an `alias` or an `external`

# User-Facing Changes
the output of `which` has changed

## some examples
```nushell
> which open
╭───┬─────────┬──────┬──────────╮

Support variables/interpolation in o>, e>, o+e> redirect (#9747)
# Description
Fixes:  #8517
Fixes: #9246
Fixes: #9709
Relative: #9723


## About the change
Before the pr, nushell only parse redirection target as a string(through
`parse_string` call).
In the pr, I'm trying to make the value more generic(using `parse_value`
with `SyntaxShape::Any`)

And during eval stage, we guard it to only eval `String`,
`StringInterpolation`, `FullCellPath`, `FilePath`, so other type of
redirection target like `1ms` won't be permitted.

# User-Facing Changes

After the pr: redirection support something like the following:
1. `let a = "x"; cat toolkit.nu o> $a`
2. `let a = "x"; cat toolkit.nu o> $"($a).txt"`
3. `cat toolkit.nu out> ("~/a.txt" | path expand)`

sync default config / env with default behaviour without any configuration (#9676)
related PRs and issues
- supersedes https://github.com/nushell/nushell/pull/9633
- should close https://github.com/nushell/nushell/issues/9630

# Description
this PR updates the `default_config.nu` config file and the `config.rs`
module in `nu_protocol` so that the default behaviour of Nushell,
without any config, and the one with `default_config.nu` and
`default_env.nu` are the same.

## changelog
- 3e2bfc9bb: copy the structure of `default_config.nu` inside the
implementation of `Default` in the `config.rs` module for easier check
of the default values
- e25e5ccd6: sync all the *simple* config fields, i.e. the
non-structured ones
- ae7e8111c: set the `display_output` hook to always run `table`
- a09a1c564: leave only the default menus => i've removed
`commands_menu`, `vars_menu` and `commands_with_description`

## todo
- [x] ~~check the defaults in `$env.config.explore`~~ done in 173bdbba5
and b9622084c
- [x] ~~check the defaults in `$env.config.color_config`~~ done in
c411d781d => the theme is now `{}` by default so that it's the same as
the default one with `--no-config`
- [x] ~~check the defaults `$env.config.keybindings`~~ done in 715a69797
- already available with the selected mode: `completion_previous`,
`next_page`, `undo_or_previous_page`, `yank`, `unix-line-discard` and
`kill-line`, e.g. in *vi* mode, `unlix-line-discard` is done in NORMAL
mode with either `d0` from the end of the line or `dd` from anywhere in
the line and `kill-line` is done in NORMAL mode with `shift + d`. these
bindings are available by default in *emacs* mode as well.
- previously with removed custom menus: `commands_menu`, `vars_menu` and
`commands_with_description`
- [x] ~~check `$env.config.datetime_format`~~ done in 0ced6b8ec => as
there is no *human* format for datetimes, i've commented out both
`$env.config.datetime_format` fields
- [x] ~~fix `default_env.nu`~~ done in 67c215011

# User-Facing Changes
this should not change anything, just make sure the default behaviour of
Nushell and the `default_config.nu` are in sync.

Clean up tests containing unnecessary cwd: tokens (#9692)
# Description
The working directory doesn't have to be set for those tests (or would
be the default anyways). When appropriate also remove calls to the
`pipeline()` function. In most places kept the diff minimal and only
removed the superfluous part to not pollute the blame view. With simpler
tests also simplified things to make them more readable overall (this
included removal of the raw string literal).

add match guards (#9621)
## description

this pr adds [match
guards](https://doc.rust-lang.org/reference/expressions/match-expr.html#match-guards)
to match patterns
```nushell
match $x {
   _ if $x starts-with 'nu' => {},
   $x => {}
}
```

these work pretty much like rust's match guards, with few limitations:

1. multiple matches using the `|` are not (yet?) supported
 
```nushell
match $num {
    0 | _ if (is-odd $num) => {},
    _ => {}
}
```

2. blocks cannot be used as guards, (yet?)

```nushell
match $num {
    $x if { $x ** $x == inf } => {},
     _ => {}
}
```

## checklist
- [x] syntax
- [x] syntax highlighting[^1]
- [x] semantics
- [x] tests
- [x] clean up

Custom command input/output types (#9690)
# Description

This adds input/output types to custom commands. These are input/output
pairs that related an input type to an output type.

For example (a single int-to-int input/output pair):

```
def foo []: int -> int { ... }
```

You can also have multiple input/output pairs:
```
def bar []: [int -> string, string -> list<string>] { ... }
```

These types are checked during definition time in the parser. If the
block does not match the type, the user will get a parser error.

This `:` to begin the input/output signatures should immediately follow
the argument signature as shown above.

The PR also improves type parsing by re-using the shape parser. The
shape parser is now the canonical way to parse types/shapes in user
code.

This PR also splits `extern` into `extern`/`extern-wrapped` because of
the parser limitation that a multi-span argument (which Signature now
is) can't precede an optional argument. `extern-wrapped` now takes the
required block that was previously optional.

# User-Facing Changes

The change to `extern` to split into `extern` and `extern-wrapped` is a
breaking change.

Input output checking (#9680)
# Description

This PR tights input/output type-checking a bit more. There are a lot of
commands that don't have correct input/output types, so part of the
effort is updating them.

This PR now contains updates to commands that had wrong input/output
signatures. It doesn't add examples for these new signatures, but that
can be follow-up work.

# User-Facing Changes

BREAKING CHANGE BREAKING CHANGE

This work enforces many more checks on pipeline type correctness than
previous nushell versions. This strictness may uncover incompatibilities
in existing scripts or shortcomings in the type information for internal
commands.

Fix headers command handling of missing values (#9603)
# Description
This fixes the `headers` command handling of missing values (issue
#9602). Previously, each row in the table would have its columns set to
be exactly equal to the first row even if it had less columns than the
first row. This would cause to values magically change their column or
cause panics in other commands if rows ended up having more columns than
values.

# Tests
Added a missing values  test for the `headers` command

REFACTOR: move the 0% commands to nu-cmd-extra (#9404)
requires
- https://github.com/nushell/nushell/pull/9455

# ⚙️ Description
in this PR i move the commands we've all agreed, in the core team, to
move out of the core Nushell to the `extra` feature.

> **Warning**
> in the first commits here, i've
> - moved the implementations to `nu-cmd-extra`
> - removed the declaration of all the commands below from `nu-command`
> - made sure the commands were not available anymore with `cargo run --

## the list of commands to move
with the current command table downloaded as `commands.csv`, i've run
```bash
let commands = (
    open commands.csv
    | where is_plugin == "FALSE" and category != "deprecated"
    | select name category "approv. %"
    | rename name category approval
    | insert treated {|it| (

        ($it.name | str starts-with "bits") or  # see https://github.com/nushell/nushell/pull/9241
        ($it.name | str starts-with "dfr")      # see https://github.com/nushell/nushell/pull/9327

- give `cwd` to `nu!`

Let with pipeline (#9589)
# Description

This changes the default behaviour of `let` to be able to take a
pipeline as its initial value.

For example:

```
> let x = "hello world" | str length
```

This is a change from the existing behaviour, where the right hand side
is assumed to be an expression. Pipelines are more general, and can be
more powerful.

My google foo is failing me, but this also fixes this issue:

```
let x = foo
```

Currently, this reads `foo` as a bareword that gets converted to a
string rather than running the `foo` command. In practice, this is
really annoying and is a really hard to spot bug in a script.

# User-Facing Changes

BREAKING CHANGE BREAKING CHANGE

`let` gains the power to be assigned via a pipeline. However, this
changes the behaviour of `let x = foo` from assigning the string "foo"
to `$x` to being "run the command `foo` and give the result to `$x`"

remove let-env, focus on mutating $env (#9574)
# Description

For years, Nushell has used `let-env` to set a single environment
variable. As our work on scoping continued, we refined what it meant for
a variable to be in scope using `let` but never updated how `let-env`
would work. Instead, `let-env` confusingly created mutations to the
command's copy of `$env`.

So, to help fix the mental model and point people to the right way of
thinking about what changing the environment means, this PR removes
`let-env` to encourage people to think of it as updating the command's
environment variable via mutation.

Before:

```
let-env FOO = "BAR"
```

Now:

```
$env.FOO = "BAR"
```

It's also a good reminder that the environment owned by the command is
in the `$env` variable rather than global like it is in other shells.

# User-Facing Changes

BREAKING CHANGE BREAKING CHANGE

This completely removes `let-env FOO = "BAR"` so that we can focus on
`$env.FOO = "BAR"`.

clean up config by removing legacy options (#9496)
# Description

This PR cleans up the deprecated legacy config options that were
deprecated in nushell version 0.72.0. These are the config points that
were in the root of the config but also duplicated in the nested
structures. For instance `use_ls_colors` was in the root of the config
and also in the `ls.use_ls_colors` nested structure. This was originally
done to preserve backwards compatibility when nested structures were
introduced in the config file.

Here's a list of the legacy config points that were removed.

- `use_ls_colors` - previously replaced with `ls.use_ls_colors`
- `rm_always_trash` - previously replaced with `rm.always_trash`
- `history_file_format` - previously replaced with `history.file_format`
- `sync_history_on_enter` - previously replaced with
`history.sync_on_enter`
- `max_history_size` - previously replaced with `history.max_size`
- `quick_completions` - previously replaced with `completions.quick`
- `partial_completions` - previously replaced with `completions.partial`
- `max_external_completion_results` - previously replaced with
`completions.external.max_results`
- `completion_algorithm` - previously replaced with
`completions.algorithm`
- `case_sensitive_completions` - previously replaced with
`completions.case_sensitive`
- `enable_external_completion` - previously replaced with
`completions.external.enable`
- `external_completer` - previously replaced with
`completions.external.completer`
- `table_mode` - previously replaced with `table.mode`
- `table_index_mode` - previously replaced with `table.index_mode`
- `table_trim` - previously replaced with `table.trim`
- `show_clickable_links_in_ls` - previously replaced with
`ls.clickable_links`
- `cd_with_abbreviations` - previously replaced with `cd.abbreviations`
- `filesize_metric` - previously replaced with `filesize.metric`
- `filesize_format` - previously replaced with `filesize.format`
- `cursor_shape_vi_insert` - previously replaced with
`cursor_shape.vi_insert`
- `cursor_shape_vi_normal` - previously replaced with
`cursor_shape.vi_normal`
- `cursor_shape_emacs` - previously replaced with `cursor_shape.emacs`

Removes log_level from the config since it doesn't do anything any
longer. We moved log-level to a nushell parameter some time ago.

Renames history_isolation to isolation in the config.nu for consistency.

Fixes a couple bugs where values weren't being set in the "//
Reconstruct" sections (history_isolation, table_show_empty).

Reorganized/Moved things around a tiny bit and added a few comments.

# User-Facing Changes

history.histor_isolation is now history.isolation.
If anyone is still using the legacy config points, deprecated since
0.72.0 2022-11-29, their config will break.

split $nu variable into scope commands and simpler $nu (#9487)
# Description

This splits off `scope` from `$nu`, creating a set of `scope` commands
for the various types of scope you might be interested in.

This also simplifies the `$nu` variable a bit.

# User-Facing Changes

This changes `$nu` to be a bit simpler and introduces a set of `scope`
subcommands.

Revert #8395 "Treat empty pipelines as pass-through" (#9472)
In my view we should revert nushell/nushell#8395 for now

## Potentially inconsistent application of semantic change
#8395 (1d5e7b441b) was loosening the type
coercion rules significantly, to let missing data / void returns that
were either expressed by `PipelineData::Empty` or the `Value::nothing`
be accept by specifically those commands/operations that made use of
`PipelineData::into_iter_strict()`. This could apply the new rules
inconsistently.

## Turning explicit failures into silent continuations
Furthermore the effect of this breaking change to the missing data
semantics could make previous errors into silent failures.
This could either just reduce the effectiveness of teaching error
messages in interactive use:

### Contrived example before
```bash
> cd . | where blah
Error: nu:🐚:only_supports_this_input_type

  × Input type not supported.
   ╭─[entry #13:1:1]
 1 │ cd . | where blah
   ·        ──┬──┬
   ·          │  ╰── input type: null
   ·          ╰── only list, binary, raw data or range input data is supported
   ╰────
```
### ...after, with #8395
```bash
> cd . | where blah
╭────────────╮
│ empty list │
╰────────────╯
```

In rare cases people could already try to rely on catching an error of a
downstream command to actually deal with the missing data, so it would
be a breaking change for their existing code.

## Problem with `PipelineData::into_iter_strict()`

Maybe this makes `_strict` a bit of a misnomer for this particular
iterator construction.
Further we did not actively test the `PipelineData::empty` branch before

![grafik](https://github.com/nushell/nushell/assets/15833959/c377bf1d-d47c-4c25-a342-9a348539f242)

## Parsimonious solution exists

For the motivating issue https://github.com/nushell/nushell/issues/8393
there already exists a fix that makes `ls` more consistent with the type
system by returning an empty `Value::List`

Treat empty pipelines as pass-through (#8395)
# Description

This allows empty pipelines to pass their emptiness through a filter.
This helps fix issues like trying to run a filter on an `ls` in an empty
directory. It also feels a bit more reasonable that a filter filters
what is *there* but doesn't require something to be there.

fixes #8393

# User-Facing Changes

No breaking changes (that I know of). Should allow filtering to be a
little less surprising with emptiness.

Fix missing file names from rm errors (#9120)
# Description
Fixes a small bug with `rm` where names of files which couldn't be
deleted due to error were not printed.

Fixes https://github.com/nushell/nushell/issues/9004

# User-Facing Changes
Slightly different error message than previously. Nothing significant,
though.

The new error message looks like this
```
~/Projects/rust/nushell> rm /proc/1/mem                                                                                                                                                            05/06/2023 01:13:23 PM

Break up interdependencies of command crates (#9429)
# 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)

Trying to fix #9394. 

The problem with PR #9159 seems to be when searching for multiple terms,
each term is checked against the original values. It outputs a new value
for each such check, thus introducing replication for each search term.
As a result, it works fine with num of search term = 1.

don't allow save command to save both stdout and stderr to the same file (#9368)
# Description
It's not a good idea to save `stdout` and `stderr` to the same file from
`save` command directly.

Because it saves `stdout` and `stderr` in different thread, which leads
to in-consistent output. As replace, we can use `o+e` redirection to fix
the issue

# User-Facing Changes
```
❯ do -i { "aa" } | save foo.txt -e foo.txt
Error:   × input and stderr input to same file

use "search_result" style to colorize matching strings (fixes #9275) (#9326)
This change introduces new `search_result` style supported in the color
config. The change also removes obsolete check for `config.ls_colors`
for computing the style. `config.ls_colors` has been removed last year,
so this removes the reference to the obsolete flag, along with a cleanup
that removes all the code that used to rely on ls_colors for
highlighting search results.

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.~~

Avoid blocking when o+e> redirects too much stderr message (#8784)
# 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}
        }
    ]
}
```

REFACTOR: remove the shell commands (#8415)
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`
-  `toolkit test stdlib`

# After Submitting
the website will have to be regenerated to reflect the removed commands
👍

Parameter defaults to $nu.scope.commands (#9152)
(*third* try at posting this PR, #9104, like #9084, got polluted with
unrelated commits. I'm never going to pull from the github feature
branch again!)

# Description
<!--
Thank you for improving Nushell. Please, check our [contributing
guide](../CONTRIBUTING.md) and talk to the core team before making major
changes.

Description of your pull request goes here. **Provide examples and/or
screenshots** if your changes affect the user experience.

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, }
}

Fix negative precision round with ints (issue #9049) (#9073)
# Description
Before this PR, `math round` ignores the input if it's an `int`. This
results in the following behaviour:
```
> 123 | math round --precision -1
123
```
When the correct result is 120.

Now `int values` are converted to `float values` before actually
rounding up the number in order to take advantage of the float
implementation.

Fixes #9049.

1. If the filesystem is not touched, don't use the filesystem
playground/sandbox
2. If the filesystem is not touched, don't specify the `cwd`
3. If the command is short, don't bother wrapping it in `pipeline()`
4. If the command doesn't have quotes, don't bother with a `r#"..."#`
raw string

Add extern def which allows raw arguments (#8956)
# Description

Extends the `extern` syntax to allow commands that accept raw arguments.
This is mainly added to allow wrapper type scripts for external
commands.

This is an example on how this can be used:

```nushell
extern foo [...rest] { 
  print ($rest | str join ',' ) 
}
foo --bar baz -- -q -u -x
# => --bar,baz,--,-q,-u,-x
```

(It's only possible to accept a single ...varargs argument in the
signature)

# User-Facing Changes

No breaking changes, just extra possibilities.

# Tests + Formatting

Added a test for this new behaviour and ran the toolkit pr checker

# After Submitting

This is advanced functionality but it should be documented, I will open
a new PR on the book for that

Fix unexpected flattening of data by par-each (Issue #8497) (#9007)
# Description
Previously, `par-each` acted like a `flatmap`: first mapping the data,
then applying a `flatten`. This is unlike `each`, which just maps the
data. Now `par-each` works like `each` in this regard, leaving nested
data unflattened.

Fixes #8497

# User-Facing Changes
Previously:
`[1 2 3] | par-each {|e| [$e, $e] }` --> `[1,1,2,2,3,3]` 
Now:
`[1 2 3] | par-each {|e| [$e, $e] }` --> `[[1,1],[2,2],[3,3]]`

# Tests
This adds one test that verifies the lack of flattening for `par-each`.

Bump tabled dependency to 0.11 (#8922)
close? #8060

Quite a bit of refactoring took place.
I believe a few improvements to collapse/expand were made.

I've tried to track any performance regressions and seems like it is
fine.

I've noticed something different now with default configuration path or
something in this regard?
So I might missed something while testing because of this.

Requires some oversight.

Reuse the cached parse results of parsed files (#8949)
# Description

This does a lookup in the cache of parsed files to see if a span can be
found for a file that was previously loaded with the same contents, then
uses that span to find the parsed block for that file. The end result
should, in theory, be identical but doesn't require any reparsing or
creating new blocks/new definitions that aren't needed.

This drops the sg.nu benchmark from:

unify the *-BuiltinVar parser errors (#8944)
# Description

this pr condenses `MutBuiltinVar`, `LetBuiltinVar` and `ConstBuiltinVar`
into one error:
```nu
Error: nu::parser::name_is_builtin_var

  × `in` used as variable name.
   ╭─[entry #69:1:1]
 1 │ let in = 420
   ·     ─┬
   ·      ╰── already a builtin variable
   ╰────
  help: 'in' is the name of a builtin Nushell variable and cannot be used
        as a variable name
```

it also fixes this case which was previously not handled
```nu
let $nu = 420 # this variable would have been 'lost'
```

Revert numberlike parsing restriction (#8845)
# Description

This effectively reverts #8635. We shipped this change with 0.78 and
received many comments/issues related to this restriction feeling like a
step backward.

fixes: #8844 
(and probably other issues)

# User-Facing Changes

Returns numbers and number-like values to being allowed to be bare
words. Examples: `3*`, `1fb43`, `4,5`, and related.

# 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
- `cargo run -- crates/nu-std/tests/run.nu` to run the tests for the
standard library

> **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

Only add the std lib files once (#8830)
# 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.

Add regex separators for split row/list/column (#8707)
# Description

Verified on discord with maintainer

Change adds regex separators in split rows/column/list. The primary
motivating reason was to make it easier to split on separators with
unbounded whitespace without requiring a lot of trim jiggery. But,
secondary motivation is the same as the set of all motivations for
adding split regex features to most languages.

# User-Facing Changes

Adds -r option to split rows/column/list.

# Tests + Formatting

Ran tests, however tests.nu fails with unrelated errors:

```

Upon investigating seeing this difference:

╰───┴─────────────────────────────────────────────────────────────────────────────────────────────────────────╯
```

This seems unrelated to my changes, but can investigate further if
desired.
