Fix match example whitespace (#9961)
I was looking up `match` documentation and noticed that the formatting
was a bit off for the last example (starts on the wrong line, is several
columns too far to the right).

Fix duration type to not report months or years (#9632)
<!--

- this PR should close #xxxx
- fixes #xxxx

you can also mention related issues, PRs or discussions!
-->
This PR should close #8036, #9028 (in the negative) and #9118.

Fix for #9118 is a bit pedantic.  As reported, the issue is:
```
> 2023-05-07T04:08:45+12:00 - 2019-05-10T09:59:12+12:00
3yr 12month 2day 18hr 9min 33sec
```
with this PR, you now get:
```
> 2023-05-07T04:08:45+12:00 - 2019-05-10T09:59:12+12:00
208wk 1day 18hr 9min 33sec
```
Which is strictly correct, but could still fairly be called "weird date
arithmetic".

# Description
* [x] Abide by constraint that Value::Duration remains a number of
nanoseconds with no additional fields.
* [x] `to_string()` only displays weeks .. nanoseconds. Duration doesn't
have base date to compute months or years from.
* [x] `duration | into record` likewise only has fields for weeks ..
nanoseconds.
* [x] `string | into duration` now accepts compound form of duration
to_string() (e.g '2day 3hr`, not just '2day')
* [x] `duration | into string` now works (and produces the same
representation as to_string(), which may be compound).

# User-Facing Changes
## duration -> string -> duration
Now you can "round trip" an arbitrary duration value: convert it to a
string that may include multiple time units (a "compound" value), then
convert that string back into a duration. This required changes to
`string | into duration` and the addition of `duration | into string'.
```
> 2day + 3hr
2day 3hr # the "to_string()" representation (in this case, a compound value)
> 2day + 3hr | into string
2day 3hr # string value
> 2day + 3hr | into string | into duration
2day 3hr # round-trip duration -> string -> duration
```
Note that `to nuon` and `from nuon` already round-tripped durations, but
use a different string representation.

## potentially breaking changes
* string rendering of a duration no longer has 'yr' or 'month' phrases.
* record from `duration | into record` no longer has 'year' or 'month'
fields.
The excess duration is all lumped into the `week` field, which is the
largest time unit you can
convert to without knowing the datetime from which the duration was
calculated.

Scripts that depended on month or year time units on output will need to
be changed.

### Examples
```
> 365day
52wk 1day
## Used to be: 
## 1yr

> 365day | into record
╭──────┬────╮
│ week │ 52 │
│ day  │ 1  │
│ sign │ +  │
╰──────┴────╯

## used to be:
##╭──────┬───╮
##│ year │ 1 │
##│ sign │ + │
##╰──────┴───╯

> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns)
56wk 6day 6hr 7min 8sec 9ms 10µs 11ns
## used to be:
## 1yr 1month 3day 6hr 7min 8sec 9ms 10µs 11ns
## which looks reasonable, but was actually only correct in 75% of the years and 25% of the months in the last 4 years.

> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns) | into record
╭─────────────┬────╮
│ week        │ 56 │
│ day         │ 6  │
│ hour        │ 6  │
│ minute      │ 7  │
│ second      │ 8  │
│ millisecond │ 9  │
│ microsecond │ 10 │
│ nanosecond  │ 11 │
│ sign        │ +  │
╰─────────────┴────╯
```
Strictly speaking, these changes could break an existing user script.
Losing years and months as time units is arguably a regression in
behavior.

Also, the corrected duration calculation could break an existing script
that was calibrated using the old algorithm.

Auto-expand table based on terminal width (#9934)
# Description

This PR adds back the functionality to auto-expand tables based on the
terminal width, using the logic that if the terminal is over 100 columns
to expand.

This sets the default config value in both the Rust and the default
nushell config.

To do so, it also adds back the ability for hooks to be strings of code
and not just code blocks.

Fixed a couple tests: two which assumed that the builtin display hook
didn't use a table -e, and one that assumed a hook couldn't be a string.

Make Value::columns return slice instead of cloned Vec (#9927)
# Description
This PR changes `Value::columns` to return a slice of columns instead of
cloning said columns. If the caller needs an owned copy, they can use
`slice::to_vec` or the like. This eliminates unnecessary Vec clones
(e.g., in `update cells`).

force version to update when installing with toolkit (#9947)
# Description
`version` has always been a bit off regarding the `commit_hash`
😕

i think it was @fdncred who found this trick: `touch`ing the
`crates/nu-cmd-lang/build.rs` file
- won't change the Git index
- will force Nushell to recompile the `version` information correctly

this PR adds a call to `touch` on that file to `toolkit install`.

# User-Facing Changes
`version` should be correct when installing locally with the `toolkit`.

Nothing return type (#9935)
# Description
Fix #9928. When parsing input/output types `nothing` was incorrectly
coerced to `any`. This is addressed by changing how
[to_type](0ad1ad4277/crates/nu-protocol/src/syntax_shape.rs (L121))
method handles `nothing` syntax shape. Also `range` syntax shape is
addressed the same way.

# User-Facing Changes
`nothing` and `range` are correctly displayed in help and strictly
processed by type checking. This will break definitions that were not in
fact output nothing or range and incorrect uses of functions which input
nothing or range.

Examples of correctly defined functions:

Example script subcommand:

```
def "main addten" [x: int] {

}
```

then call it with:

```

add keybinding for search-history (#9930)
# Description

This PR adds a keybinding in the rust code for `search-history` aka
reverse-search as `ctrl+q` so it does not overwrite `history-search`
with `ctrl+r` as it does now.

This PR supercedes #9862. Thanks to @SUPERCILEX for bringing this to our
attention.

remove old deprecated commands (#9840)
# Description
in this PR i propose to remove the following old deprecated commands
- `hash base64` -> `encode base64`
- `math eval` -> `math <sub>`
- `str to-datetime` -> `into datetime`
- `str to-decimal` -> `into decimal`
- `str find-replace` -> `str replace`
- `str to-int` -> `into int`
- `keep` -> `take`
- `match` -> `find`
- `nth` -> `select`
- `pivot` -> `transpose`
- `unalias` -> `hide`
- `all?` -> `all`
- `any?` -> `any`
- `empty?` -> `is-empty`
- `build-string` -> `str join` / string concatenation with `+`
- `str lpad` -> `fill`
- `str rpad` -> `fill`
- `str collect` -> `str join`
- `old-alias` -> `alias`

so old i do not remember them at all 😮

i left the following four commands because they have been moved much
more recently i think!
- `fetch` -> `http get`
- `post` -> `http post`
- `benchmark` -> `timeit`
- `let-env`
- `date format` -> `format date`

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

This PR re-enables process management on macOS in combination with the
changes from #9693.

# User-Facing Changes
Fixes hang on exit for nested nushells on macOS (issue #9859). Nushell

Add an option to set header on border (style) (#9920)
fix #9796

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.

Fix default prompt indicators (#9914)
related to
- https://github.com/nushell/nushell/pull/9907

# Description
https://github.com/nushell/nushell/pull/9907 removed the front space
from all `PROMPT_INDICATOR`s but this is not what the default behaviour
of Nushell is, i.e. in `nu --no-config-file`.

this PR
- removes the space that is prepended by Nushell before the prompt
indicator to match the `default_env.nu`
- swaps INSERT and NORMAL in the Rust code to match the `:` and `>`
respectively in `default_env.nu`

## 🔍 try the changes
> **Warning**
> i had to comment out in my config all the `$env.PROMPT_INDICATOR... =
...` to avoid these variables to propagate to `cargo run -- -n`

in either `cargo run -- -n` or `cargo run -- --config
crates/nu-utils/src/sample_config/default_config.nu --env-config
crates/nu-utils/src/sample_config/default_env.nu`,
- see `/path/to/nushell>` as the prompt with the default `emacs` edit
mode
- run `$env.config.edit_mode = vi`
- see `/path/to/nushell:` as the INSERT prompt in Vi mode
- press Escape to go into NORMAL mode
- see `/path/to/nushell>` as the NORMAL prompt in Vi mode
- press I to go back into INSERT mode
- see `/path/to/nushell:` as the INSERT prompt in Vi mode

# User-Facing Changes
the prompts in `nu --no-config-file` and `nu --config default_config.nu
--env-config default_env.nu` should be the same 😌

Revert "Add an option to move header on borders" (#9908)
Reverts nushell/nushell#9796

This is just draft since we're seeing some issues with the latest fixes
to table drawing that just landed with #9796. We're hoping to get these
fixed, but if we're not able to fix them before the next release, we'll
need to revert (hence this PR, just in case we need it).

Add an option to move header on borders (#9796)
A patch to play with.
Need to make a few tests after all.

The question is what shall be done with `table.mode = none`, as it has
no borders.

```nu
$env.config.table.move_header = true
```

Simplify default style and match Rust code to config (#9900)
# Description

This PR aligns the default config in the Rust code to the default config
in the nushell file.

To do so, it removes closures from the default file, opting instead to
pick a simple style as default. This allows easier maintenance of both
Rust and Nushell code without removing the ability to use closures for
styling in your configuration.

The default theme is now "dark mode" in both the Rust and nushell config
code.

Obligatory screenshot:

This PR updates nushell to use the latest reedline. I swear that was the
only change I made. The other reordering stuff is by my vscode extension
I guess.

Fixed the panic when type a statement similar to let f = 'f' $ in the nushell (#9851)
- this PR should close #9596 
- fixes #9596 
- this PR should close #9826 
- fixes #9826 

fixed the following bugs:
```nu
# type following statements in the nushell
let f = 'f' $;
mut f = 'f' $;
const f = 'f' $;

# then remove variable f, it will panics
let = 'f' $;
mut  = 'f' $;
const = 'f' $;
```

Relative: #8248 

After this pr, user can define const variable inside a module.

![image](https://github.com/nushell/nushell/assets/22256154/e3e03e56-c4b5-4144-a944-d1b20bec1cbd)

And user can export const variables, the following screenshot shows how
it works (it follows
https://github.com/nushell/nushell/issues/8248#issuecomment-1637442612):

![image](https://github.com/nushell/nushell/assets/22256154/b2c14760-3f27-41cc-af77-af70a4367f2a)

## About the change
1. To make module support const, we need to change `parse_module_block`
to support `const` keyword.
2. To suport export `const`, we need to make module tracking variables,
so we add `variables` attribute to `Module`
3. During eval, the const variable may not exists in `stack`, because we
don't eval `const` when we define a module, so we need to find variables
which are already registered in `engine_state`

## One more thing to note about the const value.
Consider the following code
```
module foo { const b = 3; export def bar [] { $b } }
use foo bar
const b = 4;
bar
```
The result will be 3 (which is defined in module) rather than 4. I think
it's expected behavior.

It's something like [dynamic
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Dynamic-Binding-Tips.html)
vs [lexical
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Lexical-Binding.html)
in lisp like language, and lexical binding should be right behavior
which generates more predicable result, and it doesn't introduce really
subtle bugs in nushell code.

What if user want dynamic-binding?(For example: the example code returns
`4`)
There is no way to do this, user should consider passing the value as
argument to custom command rather than const.

## TODO
- [X] adding tests for the feature.
- [X] support export const out of module to use.

Replace &Span with Span since Span is Copy (#9770)
# Description
`Span` is `Copy`, so we probably should not be passing references of
`Span` around. This PR replaces all instances of `&Span` with `Span`,
copying spans where necessary.

# User-Facing Changes
This alters some public functions to take `Span` instead of `&Span` as
input. Namely, `EngineState::get_span_contents`,
`nu_protocol::extract_value`, a bunch of the math commands, and
`Gstat::gstat`.

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
No breaking changes, but Records can now also be passed to `http
<subcommand> -H`.
