# Description
For `#` to start a comment, then it either need to be the first
character of the token or prefixed with ` ` (space).

So now you can do this:
```

Allow both NU_PLUGIN_DIRS const and env at the same time (#14553)
# Description

Fix #14544 and is also the reciprocal of #14549.

Before: If both a const and env `NU_PLUGIN_DIRS` were defined at the
same time, the env paths would not be used.
After: The directories from `const NU_PLUGIN_DIRS` are searched for a
matching filename, and if not found, `$env.NU_PLUGIN_DIRS` directories
will be searched.

Before: `$env.NU_PLUGIN_DIRS` was unnecessary set both in main() and in
default_env.nu
After: `$env.NU_PLUGIN_DIRS` is only set in main()

Before: `$env.NU_PLUGIN_DIRS` was set to `plugins` in the config
directory
After: `$env.NU_PLUGIN_DIRS` is set to an empty list and `const
NU_PLUGIN_DIRS` is set to the directory above.

Also updates `sample_env.nu` to use the `const`

# User-Facing Changes

Most scenarios should work just fine as there continues to be an
`$env.NU_PLUGIN_DIRS` to append to or override.

However, there is a small chance of a breaking change if someone was
*querying* the old default `$env.NU_PLUGIN_DIRS`.

# Tests + Formatting

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

Also updated the `env` tests and added one for the `const`.

Use const NU_LIB_DIRS in startup (#14549)
# Description

A slower, gentler alternative to #14531, in that we're just moving one
setting *out* of `default_env.nu` in this PR ;-).

All this does is transition from using `$env.NU_LIB_DIRS` in the startup
config to `const $NU_LIB_DIRS`. Also updates the `sample_env.nu` to
reflect the changes.

Details:

Before: `$env.NU_LIB_DIRS` was unnecessary set both in `main()` and in
`default_env.nu`
After: `$env.NU_LIB_DIRS` is only set in `main()`

Before: `$env.NU_LIB_DIRS` was set to `config-dir/scripts` and
`data-dir/completions`
After: `$env.NU_LIB_DIRS` is set to an empty list, and `const
NU_LIB_DIRS` is set to the directories above

Before: Using `--include-path (-I)` would set the `$env.NU_LIB_DIRS`
After: Using `--include-path (-I)` sets the constant `$NU_LIB_DIRS`

# User-Facing Changes

There shouldn't be any breaking changes here. The `$env.NU_LIBS_DIRS`
still works for most cases. There are a few areas we need to clean-up to
make sure that the const is usable (`nu-check`, et. al.) but they will
still work in the meantime with the older `$env` version.

# Tests + Formatting

* Changed the Type-check on the `$env` version.
* Added a type check for the const version.

- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

normalize special characters in module names to allow variable access (#14353)
Fixes #14252

# User-Facing Changes

- Special characters in module names are replaced with underscores when
  importing constants, preventing "expected valid variable name":

```nushell
> module foo-bar { export const baz = 1 }
> use foo-bar
> $foo_bar.baz
```

- "expected valid variable name" errors now include a suggestion list:

```nushell
> module foo-bar { export const baz = 1 }
> use foo-bar
> $foo-bar
Error: nu::parser::parse_mismatch_with_did_you_mean

Make Hooks fields non-optional to match the new config defaults (#14345)
# Description
Follow up to #14341. Changes the fields of `Hooks` to `Vec` or `Hashmap`
to match the new config defaults.

# User-Facing Changes
Mostly the same as #14341. `pre_prompt` and `pre_execution` must now be
a list, and `env_change` must be a record.

Always populate config record during startup (#14435)
# Description

As a bit of a follow-on to #13802 and #14249, this (pretty much a
"one-line" change) really does *always* populate the `$env.config`
record with the `nu-protocol::config` defaults during startup. This
means that an `$env.config` record is value (with defaults) even during:

* `nu -n` to suppress loading of config files
* `nu -c <commandstring>`
* `nu <script>`

# User-Facing Changes

There should be no case in which there isn't a valid `$env.config`.

* Before:

  ```nushell
  nu -c "$env.config"
  # -> Error
  ```

* After:

  ```nushell
  nu -c "$env.config"
  # -> Default $env.config record
  ```

Startup time impact is negligible (17.072µs from `perf!` on my system) -
Seems well worth it.

# Tests + Formatting

Remove long-unused autoenv tests (#14436)
# Description

The `.nu-env` file feature was removed some time ago (probably in the
engine-q upgrade?). The tests, however, still remained as dead-code, so
this is just some basic clean-up.

If this feature was ever implemented again, the tests would need to be
rewritten anyway due to the changes in the way config is handled.

Change append operator to concatenation operator (#14344)
# Description

The "append" operator currently serves as both the append operator and
the concatenation operator. This dual role creates ambiguity when
operating on nested lists.

```nu
[1 2] ++ 3     # appends a value to a list [1 2 3]
[1 2] ++ [3 4] # concatenates two lists    [1 2 3 4]

[[1 2] [3 4]] ++ [5 6]
# does this give [[1 2] [3 4] [5 6]]
# or             [[1 2] [3 4] 5 6]  
```

Another problem is that `++=` can change the type of a variable:
```nu
mut str = 'hello '
$str ++= ['world']
($str | describe) == list<string>
```

Note that appending is only relevant for lists, but concatenation is
relevant for lists, strings, and binary values. Additionally, appending
can be expressed in terms of concatenation (see example below). So, this
PR changes the `++` operator to only perform concatenation.

# User-Facing Changes

Using the `++` operator with a list and a non-list value will now be a
compile time or runtime error.
```nu
mut list = []
$list ++= 1 # error
```
Instead, concatenate a list with one element:
```nu
$list ++= [1]
```
Or use `append`:
```nu
$list = $list | append 1
```

# After Submitting

Update book and docs.

return accurate type errors from blocks/expressions in type unions (#14420)
# User-Facing Changes

- `expected <type>` errors are now propagated from
  `Closure | Block | Expression` instead of falling back to
  "expected one of..." for the block:

Before:

```nushell
def foo [bar: bool] {}
if true {} else { foo 1 }
                ────┬────
                    ╰── expected one of a list of accepted shapes: [Block, Expression]
```

After:

```nushell
if true {} else { foo 1 }

Always load default env/config values (#14249)
# Release-Notes Short Description

* Nushell now always loads its internal `default_env.nu` before the user
`env.nu` is loaded, then loads the internal `default_config.nu` before
the user's `config.nu` is loaded. This allows for a simpler
user-configuration experience. The Configuration Chapter of the Book
will be updated soon with the new behavior.

# Description

Implements the main ideas in #13671 and a few more:

* Users can now specify only the environment and config options they
want to override in *their* `env.nu` and `config.nu`and yet still have
access to all of the defaults:
* `default_env.nu` (internally defined) will be loaded whenever (and
before) the user's `env.nu` is loaded.
* `default_config.nu` (internally defined) will be loaded whenever (and
before) the user's `config.nu` is loaded.
* No more 900+ line config out-of-the-box.
* Faster startup (again): ~40-45% improvement in launch time with a
default configuration.
* New keys that are added to the defaults in the future will
automatically be available to all users after updating Nushell. No need
to regenerate config to get the new defaults.
* It is now possible to have different internal defaults (which will be
used with `-c` and scripts) vs. REPL defaults. This would have solved
many of the user complaints about the [`display_errors`
implementation](https://www.nushell.sh/blog/2024-09-17-nushell_0_98_0.html#non-zero-exit-codes-are-now-errors-toc).
* A basic "scaffold" `config.nu` and `env.nu` are created on first
launch (if the config directory isn't present).
* Improved "out-of-the-box" experience (OOBE) - No longer asks to create
the files; the minimal scaffolding will be automatically created. If
deleted, they will not be regenerated. This provides a better
"out-of-the-box" experience for the user as they no longer have to make
this decision (without much info on the pros or cons) when first
launching.
* <s>(New: 2024-11-07) Runs the env_conversions process after the
`default_env.nu` is loaded so that users can treat `Path`/`PATH` as
lists in their own config.</s>
* (New: 2024-11-08) Given the changes in #13802, `default_config.nu`
will be a minimal file to minimize load-times. This shaves another (on
my system) ~3ms off the base launch time.
* Related: Keybindings, menus, and hooks that are already internal
defaults are no longer duplicated in `$env.config`. The documentation
will be updated to cover these scenarios.
* (New: 2024-11-08) Move existing "full" `default_config.nu` to
`sample_config.nu` for short-term "documentation" purposes.
* (New: 2024-11-18) Move the `dark-theme` and `light-theme` to Standard
Library and demonstrate their use - Also improves startup times, but
we're reaching the limit of optimization.
* (New: 2024-11-18) Extensively documented/commented `sample_env.nu` and
`sample_config.nu`. These can be displayed in-shell using (for example)
`config nu --sample | nu-highlight | less -R`. Note: Much of this will
eventually be moved to or (some) duplicated in the Doc. But for now,
this some nice in-shell doc that replaces the older
"commented/documented default".
* (New: 2024-11-20) Runs the `ENV_CONVERSIONS` process (1) after the
`default_env.nu` (allows `PATH` to be used as a list in user's `env.nu`)
and (2) before `default_config.nu` is loaded (allows user's
`ENV_CONVERSIONS` from their `env.nu` to be used in their `config.nu`).
* <s>(New: 2024-11-20) The default `ENV_CONVERSIONS` is now an empty
record. The internal Rust code handles `PATH` (and variants) conversions
regardless of the `ENV_CONVERSIONS` variable. This shaves a *very* small
amount of time off the startup.</s> Reset - Looks like there might be a
bug in `nu-enginer::env::ensure_path()` on Windows that would need to be
fixed in order for this to work.

# User-Facing Changes

By default, you shouldn't see much, if any, change when running this
with your existing configuration.

To see the greatest benefit from these changes, you'll probably want to
start with a "fresh" config. This can be easily tested using something
like:

```nushell
let temp_home = (mktemp -d)
$env.XDG_CONFIG_HOME = $temp_home
$env.XDG_DATA_HOME = $temp_home
./target/release/nu
```

You should see a message where the (mostly empty) `env.nu` and
`config.nu` are created on first start. Defaults should be the same (or
similar to) those before the PR. Please let me know if you notice any
differences.

---

Users should now specify configuration in terms of overrides of each
setting. For instance, rather than modifying `history` settings in the
monolithic `config.nu`, the following is recommended in an updated
`config.nu`:

```nu
$env.config.history = {
  file_format: sqlite,
  sync_on_enter: true
  isolation: true
  max_size: 1_000_000
}
```

or even just:

```nu
$env.config.history.file_format = sqlite
$env.config.history.isolation: true
$env.config.history.max_size = 1_000_000
```

Note: It seems many users are already appending a `source my_config.nu`
(or similar pattern) to the end of the existing `config.nu` to make
updates easier. In this case, they will likely want to remove all of the
previous defaults and just move their `my_config.nu` to `config.nu`.

Note: It should be unlikely that there are any breaking changes here,
but there's a slim chance that some code, somewhere, *expects* an
absence of certain config values. Otherwise, all config values are
available before and after this change.

Add proper config defaults for hooks (#14341)
# Release Notes Excerpt

* Hooks now default to an empty value of the proper type (e.g., `[]` or
`{}`) when not otherwise specified

# Description

```nushell
# Start with no config
nu -n
# Populate with defaults
$env.config = {}
$env.config.hooks
```

* Before: All hooks other than `display_output` were set to `null`.
Attempting to append a hook using `++=` would fail unless it had already
been assigned.
* After:
* `pre_prompt`, `pre_execution`, and `command_not_found` are set to
empty lists. This allows the user to simply append new hooks using
`++=`.
* `env_change` is set to an empty record. This allows the user to add
new hooks using `merge`, although a "helper" command would still be
useful (TODO: stdlib).

Also fixed a typo in an error message.

# User-Facing Changes

There shouldn't be any breaking changes since (before) there were no
guarantees of the hook's value/type. Previously, users would have to
check for `null` and `default` to an empty list before appending. Any
user-strategies for dealing with the problem should continue to work
after this change.

Note that, for reasons I cannot ascertain, this PR appears to have
*fixed* the `command_not_found_error_recognizes_non_executable_file`
test that was previously broken by #12953. That PR essentially rewrote
the test to match the new behavior, but it no longer tested what it was
intended to test.

Now, the test is working again as designed (and as it works in the
REPL).

# After Submitting

This will be covered in the Configuration update for #14249. This PR
will simplify several examples in the doc.

Remove the NU_DISABLE_IR option (#14293)
# Description

Removes the `NU_DISABLE_IR` option and some code related to evaluating
blocks with the AST
evaluator.

Does not entirely remove the AST evaluator yet. We still have some
dependencies on expression
evaluation in a few minor places which will take a little bit of effort
to fix.

Also changes `debug profile` to always include instructions, because the
output is a little
confusing otherwise, and removes the different options for
instructions/exprs.

# User-Facing Changes

- `NU_DISABLE_IR` no longer has any effect, and is removed. There is no
way to use the AST
  evaluator.
- `debug profile` no longer has `--exprs`, `--instructions` options.
- `debug profile` lists `pc` and `instruction` columns by default now.

# Tests + Formatting

Eval tests fixed to only use IR.

# After Submitting

- [ ] release notes
- [ ] finish removing AST evaluator, come up with solutions for the
expression evaluation.

don't run subcommand if it's surrounded with backtick quote (#14210)
# Description
Fixes: #14202
After looking into the issue, I think #13910 it's not good to cut the
span if it's in external argument.
This pr is somehow revert the change, and fix
https://github.com/nushell/nushell/issues/13431 in another way.

It introduce a new state named `State::BackTickQuote`, so if an external
arg include backtick quote, it enters the state, so backtick quote won't
be the body of a string.

# User-Facing Changes
### Before
```nushell
> ^echo `(echo aa)`
aa
> ^echo `"aa"`   # maybe it's not right to remove the inner quote.
aa
```
### After
```nushell
> ^echo `(echo aa)`
(echo aa)
> ^echo `"aa"`    # inner quote is keeped if there are backtick quote outside.
"aa"
```

Fix range contains (#14011)
# Description

This PR changes the range contains logic to take the step into account. 

```nushell
# before
2 in 1..3.. # true

# now
2 in 1..3.. # false
```

---

I encountered another issue while adding tests. Due to floating point
precision, `2.1 in 1..1.1..3` will return `false`. The floating point
error is even bigger than `f64::EPSILON` (`0.09999999999999876` vs
`2.220446049250313e-16`). This issue disappears with bigger numbers.

I tried a different algorithm (checking if the estimated number of steps
is close enough to any integer) but the results are still pretty bad:

```rust
let n_steps = (value - self.start) / self.step; // 14.999999999999988
(n_steps - n_steps.round()).abs() < f64::EPSILON // returns false
```

Maybe it can be shipped like this, the REPL already has floating point
errors (`1.1 - 1` returns `0.10000000000000009`). Or maybe there's a way
to fix this that I didn't think of. I'm open to ideas! But in any case
performing this kind of checks on a range of floats seems more niche
than doing it on a range of ints.

# User-Facing Changes

Code that depended on this behavior to check if a number is between
`start` and `end` will potentially return a different value.

fix error when exporting consts with type signatures in modules (#14118)
Fixes #14023

# Description

- Prevents "failed to find added variable" when modules export constants
  with type signatures:

```nushell
> module foo { export const bar: int = 2 }
Error: nu::parser::unknown_state

  × Internal error.
   ╭─[entry #1:1:21]

   ·                              ╰── failed to find added variable
```

- Returns `name_is_builtin_var` errors for names with type signatures:

```nushell
> let env: string = "";
Error: nu::parser::name_is_builtin_var

  × `env` used as variable name.
   ╭─[entry #1:1:5]

3af575cce7 Make plugin list read state from plugin registry file as well (#14085)
# Description

[Context on
Discord](https://discord.com/channels/601130461678272522/855947301380947968/1292279795035668583)

**This is a breaking change, due to the removal of `is_running`.**

Some users find the `plugin list` command confusing, because it doesn't
show anything different after running `plugin add` or `plugin rm`. This
modifies the `plugin list` command to also look at the plugin registry
file to give some idea of how the plugins in engine state differ from
those in the plugin registry file.

The following values of `status` are now produced instead of
`is_running`:

- `added`: The plugin is present in the plugin registry file, but not in
the engine.
- `loaded`: The plugin is present both in the plugin registry file and
in the engine, but is not running.
- `running`: The plugin is currently running, and the `pid` column
should contain its process ID.
- `modified`: The plugin state present in the plugin registry file is
different from the state in the engine.
- `removed`: The plugin is still loaded in the engine, but is not
present in the plugin registry file.
- `invalid`: The data in the plugin registry file couldn't be
deserialized, and the plugin most likely needs to be added again.

# User-Facing Changes

To `plugin list`:

* **Breaking:** The `is_running` column is removed and replaced with
`status`. Use `status == running` to filter equivalently.
* The `--plugin-config` from other plugin management commands is now
supported.
* Added an `--engine` flag which behaves more or less like before, and
doesn't load the plugin registry file at all.
* Added a `--registry` flag which only checks the plugin registry file.
All plugins appear as `added` since there is no state to compare with.

Because the default is to check both, the `plugin list` command might be
a little bit slower. If you don't need to check the plugin registry
file, the `--engine` flag does not load the plugin registry file at all,
so it should be just as fast as before.

Note that this PR adds some additional `ShellError` cases to create
standard error messages for config errors. A follow-up PR will move
usages of the old error cases to these new ones. This PR also uses
`Type::custom` in lots of places (e.g., for string enums). Not sure if

Reduce duplication in history path construction (#13475)
# Description
Currently there is a bit of chaos regarding construction of history file
paths. Various pieces of code across a number of crates reimplement the
same/similar logic:
- There is `get_history_path`, but it requires a directory parameter (it
really just joins it with a file name).
- Some places use a const for the directory parameter, others use a
string literal - in all cases the value seems to be `"nushell"`.
- Some places assume the `"nushell"` value, other plumb it down from
close to the top of the call stack.
- Some places use a constant for history file names while others assume
it.

This PR tries to make it so that the history/config path format is
defined in a single places and so dependencies on it are easier to
follow:
- It removes `get_history_path` and adds a `file_path` method to
`HistoryConfig` instead (an extra motivation being, this is a convenient
place that can be used from all creates that need a history file path)
- Adds a `nu_config_dir` function that returns the nushell configuration
directory.
- Updates existing code to rely on the above, effectively removing
duplicate uses of `"nushell"` and `NUSHELL_FOLDER` and assumptions about
file names associated with different history formats

Remove superfluous separator when there's no flag description/comment (#14007)
# Description

Fixes a small side-issue in #10977 - If a command flag didn't have a
comment/description, it would still show an unnecessary separator at the
end of the line.

This fixes that, plus uses the `: ` (colon) to separate the flag from
the description. This aligns with the way that named parameters are
handled.

Improves startup time when using std-lib (#13842)
Updated summary for commit
[612e0e2](612e0e2160)
- While folks are welcome to read through the entire comments, the core
information is summarized here.

# Description

This PR drastically improves startup times of Nushell by only parsing a
single submodule of the Standard Library that provides the `banner` and
`pwd` commands. All other Standard Library commands and submodules are
parsed when imported by the user. This cuts startup times by more than
60%.

At the moment, we have stopped adding to `std-lib` because every
addition adds a small amount to the Nushell startup time.
With this change, we should once again be able to allow new
functionality to be added to the Standard Library without it impacting
`nu` startup times.

# User-Facing Changes

* Nushell now starts about 60% faster
* Breaking change: The `dirs` (Shells) aliases will return a warning
message that it will not be auto-loaded in the following release, along
with instructions on how to restore it (and disable the message)
* The `use std <submodule> *` syntax is available for convenience, but
should be avoided in scripts as it parses the entire `std` module and
all other submodules and places it in scope. The correct syntax to
*just* load a submodule is `use std/<submodule> *` (asterisk optional).
The slash is important. This will be documented.
* `use std *` can be used for convenience to load all of the library but
still incurs the full loading-time.
* `std/dirs`: Semi-breaking change. The `dirs` command replaces the
`show` command. This is more in line with the directory-stack
functionality found in other shells. Existing users will not be impacted
by this as the alias (`shells`) remains the same.

* Breaking-change: Technically a breaking change, but probably only
impacts maintainers of `std`. The virtual path for the standard library
has changed. It could previously be imported using its virtual path (and
technically, this would have been the correct way to do it):

  ```nu
  use NU_STDLIB_VIRTUAL_DIR/std
  ```

  The path is now simply `std/`:

  ```nu
  use std
  ```

  All submodules have moved accordingly.
  

# Timings

Comparisons below were made:

* In a temporary, clean config directory using `$env.XDG_CONFIG_HOME =
(mktemp -d)`.
* `nu` was run with a release build
* `nu` was run one time to generate the default `config.nu` (etc.) files
- Otherwise timings would include the user-prompt
* The shell was exited and then restarted several times to get timing
samples

(Note: Old timings based on 0.97 rather than 0.98, but in the range of
being accurate)

| Scenario | `$nu.startup-time` |
| --- | --- |
| 0.97.2
([aaaab8e](aaaab8e070))
Without this PR | 23ms - 24ms |
| This PR with deprecated commands | 9ms - <11ms |
| This PR after deprecated commands are removed in following release |
8ms - <10ms |
| Final PR (remove deprecated), using `--no-std-lib` | 6.1ms to 6.4ms |
| Final PR (remove deprecated), using `--no-config-file` | 3.1ms - 3.6ms
|
| Final PR (remove deprecated), using `--no-config-file --no-std-lib` |
1ms - 1.5ms |

*These last two timings point to the opportunity for further
optimization (see comment in thread below (will link once I write it).*

# Implementation details for future maintenance

* `use std banner` is a ridiculously deceptive call. That call parses
and imports *all* of `std` into scope. Simply replacing it with `use
std/core *` is essentially what saves ~14-15ms. This *only* imports the
submodule with the `banner` and `pwd` commands.

* From the code-comments, the reason that `NU_STDLIB_VIRTUAL_DIR` was
used as a prefix was so that there wouldn't be an issue if a user had a
`./std/mod.nu` in the current directory. This does **not** appear to be
an issue. After removing the prefix, I tested with both a relative
module as well as one in the `$env.NU_LIB_DIRS` path, and in all cases
the *internal* `std` still took precedence.

* By removing the prefix, users can now `use std` (and variants) without
requiring that it already be parsed and in scope.

* In the next release, we'll stop autoloading the `dirs` (shells)
functionality. While this only costs an additional 1-1.5ms, I think it's
better moved to the `config.nu` where the user can optionally remove it.
The main reason is its use of aliases (which have also caused issues) -
The `n`, `p`, and `g` short-commands are valuable real-estate, and users
may want to map these to something else.
  
For this release, there's an `deprecated_dirs` module that is still
autoloaded. As with the top-level commands, use of these will give a
deprecation warning with instructions on how to handle going forward.

To help with this, moved the aliases to their own submodule inside the
`dirs` module.

* Also sneaks in a small change where the top-level `dirs` command is
now the replacement for `dirs show`

* Fixed a double-import of `assert` in `dirs.nu`
* The `show_banner` step is replaced with simply `banner` rather than
re-importing it.

* A `virtual_path` may now be referenced with either a forward-slash or
a backward-slash on Windows. This allows `use std/<submodule>` to work
on all platforms.

# Performance side-notes:

* Future parsing and/or IR improvements should improve performance even
further.
* While the existing load time penalty of `std-lib` was not noticeable
on many systems, Nushell runs on a wide-variety of hardware and OS
platforms. Slower platforms will naturally see a bigger jump in
performance here. For users starting multiple Nushell sessions
frequently (e.g., `tmux`, Zellij, `screen`, et. al.) it is recommended
to keep total startup time (including user configuration) under ~250ms.

# Tests + Formatting

* All tests are green

* Updated tests:
- Removed the test that confirmed that `std` was loaded (since we
don't).
- Removed the `shells` test since it is not autoloaded. Main `dirs.nu`
functionality is tested through `stdlib-test`.
- Many tests assumed that the library was fully loaded, because it was
(even though we didn't intend for it to be). Fixed those tests.
- Tests now import only the necessary submodules (e.g., `use
std/assert`, rather than `use std assert`)
- Some tests *thought* they were loading `std/log`, but were doing so
improperly. This was masked by the now-fixed "load-everything-into-scope
bug". Local CI would pass due the `$env.NU_LOG_<...>` variables being
inherited from the calling process, but would fail in the "clean" GitHub
CI environment. These tests have also been fixed.

 * Added additional tests for the changes

Fix panic on too few arguments for custom function (#10395)
# Description
Old code was comparing remaining positional arguments with total number
of arguments, where it should've compared remaining positional with
with remaining arguments of any kind. This means that if a function was
given too few arguments, `calculate_end_span` would believe that it
actually had too many arguments, since after parsing the first few
arguments, the number of remaining arguments needed were fewer than the
*total* number of arguments, of which we had used several.

Fixes #9072

Fixes: https://github.com/nushell/nushell/issues/12069
Fixes: https://github.com/nushell/nushell/issues/8385

Extracted from #10381

## Bonus

It also improves the error handling on missing positional arguments
before keywords (no longer crashing since #9851). Instead of just giving
the keyword to the parser for the missing positional, we give an
explicit error about a missing positional argument. I would like better
descriptions than "missing var_name" though, but I'm not sure if that's
available without

Old error
```

Set current working directory at startup (#12953)
This PR sets the current working directory to the location of the
Nushell executable at startup, using `std::env::set_current_dir()`. This
is desirable because after PR
https://github.com/nushell/nushell/pull/12922, we no longer change our
current working directory even after `cd` is executed, and some OS might
lock the directory where Nushell started.

The location of the Nushell executable is chosen because it cannot be
removed while Nushell is running anyways, so we don't have to worry
about OS locking it.

This PR has the side effect that it breaks buggy command even harder.
I'll keep this PR as a draft until these commands are fixed, but it
might be helpful to pull this PR if you're working on fixing one of
those bugs.

Error on non-zero exit statuses (#13515)
# Description
This PR makes it so that non-zero exit codes and termination by signal
are treated as a normal `ShellError`. Currently, these are silent
errors. That is, if an external command fails, then it's code block is
aborted, but the parent block can sometimes continue execution. E.g.,
see #8569 and this example:
```nushell
[1 2] | each { ^false }
```

Before this would give:
```
╭───┬──╮
│ 0 │  │
│ 1 │  │
╰───┴──╯
```

Now, this shows an error:
```
Error: nu:🐚:eval_block_with_input

  × Eval block failed with pipeline input
   ╭─[entry #1:1:2]
 1 │ [1 2] | each { ^false }
   ·  ┬
   ·  ╰── source value
   ╰────

Error: nu:🐚:non_zero_exit_code

  × External command had a non-zero exit code
   ╭─[entry #1:1:17]
 1 │ [1 2] | each { ^false }
   ·                 ──┬──
   ·                   ╰── exited with code 1
   ╰────
```

This PR fixes #12874, fixes #5960, fixes #10856, and fixes #5347. This
PR also partially addresses #10633 and #10624 (only the last command of
a pipeline is currently checked). It looks like #8569 is already fixed,
but this PR will make sure it is definitely fixed (fixes #8569).

# User-Facing Changes
- Non-zero exit codes and termination by signal now cause an error to be
thrown.
- The error record value passed to a `catch` block may now have an
`exit_code` column containing the integer exit code if the error was due
to an external command.
- Adds new config values, `display_errors.exit_code` and
`display_errors.termination_signal`, which determine whether an error
message should be printed in the respective error cases. For
non-interactive sessions, these are set to `true`, and for interactive
sessions `display_errors.exit_code` is false (via the default config).

# Tests
Added a few tests.

# After Submitting
- Update docs and book.
- Future work:
- Error if other external commands besides the last in a pipeline exit
with a non-zero exit code. Then, deprecate `do -c` since this will be
the default behavior everywhere.
- Add a better mechanism for exit codes and deprecate
`$env.LAST_EXIT_CODE` (it's buggy).

Currently the parser and the documentation generation use the signature
of the command, which means that it doesn't pick up on the changed name
of the `main` block, and therefore shows the name of the command as
"main" and doesn't find the subcommands. This PR changes the
aforementioned places to use the block signature to fix these issues.
This closes #13397. Incidentally it also causes input/output types to be
shown in the help, which is kinda pointless for scripts since they don't
operate on structured data but maybe not worth the effort to remove.

Fix bugs and UB in bit shifting ops (#13663)
# Description
Fixes #11267

Shifting by a `shift >= num_bits` is undefined in the underlying
operation. Previously we also had an overflow on negative shifts for the
operators `bit-shl` and `bit-shr`
Furthermore I found a severe bug in the implementation of shifting of
`binary` data with the commands `bits shl` and `bits shr`, this
categorically produced incorrect results with shifts that were not
`shift % 4 == 0`. `bits shr` also was able to produce outputs with
different size to the input if the shift was exceeding the length of the
input data by more than a byte.

# User-Facing Changes
It is now an error trying to shift by more than the available bits with:
- `bit-shl` operator
- `bit-shr` operator
