This PR implements PWD-per-drive as described in discussion #14355
# Description
On Windows, CMD or PowerShell assigns each drive its own current
directory. For example, if you are in 'C:\Windows', switch to 'D:', and
navigate to 'D:\Game', you can return to 'C:\Windows' by simply typing
'C:'.
This PR enables Nushell on Windows to have the same capability, allowing
each drive to maintain its own PWD (Present Working Directory).
# User-Facing Changes
Currently, 'cd' or 'ls' only accept absolute paths if the path starts
with 'C:' or another drive letter. With PWD-per-drive, users can use
'cd' (or auto cd) and 'ls' in the same way as 'cd' and 'dir' in
PowerShell, or similarly to 'cd' and 'dir' in CMD (noting that cd in CMD
has slightly different behavior, 'cd' for another drive only changes
current directory of that drive, but does not switch there).
Interaction example on switching between drives:
```Nushell
~>D:
D:\>cd Test
D:\Test\>C:
~>D:
D:\Test\>C:
~>cd D:..
D:\>C:x/../y/../z/..
~>cd D:Test\Test
D:\Test\Test>C:
~>D:...
D:\>
```
Interaction example on auto-completion at cmd line:
```Nushell
~>cd D:\test[Enter]
D:\test>~[Enter]
~>D:[TAB]
~>D:\test[Enter]
D:\test>c:.c[TAB]
c:\users\nushell\.cargo\ c:\users\nushell\.config\
```
Interaction example on pass PWD-per-drive to child process: (Note CMD
will use it, but PowerShell will ignore it though it still prepares such
info for child process)
```Nushell
~>cd D:\Test
D:\Test>cd E:\Test
E:\Test\>~
~>CMD
Microsoft Windows [Version 10.0.22631.4460]

```
# Brief Change Description
1.Added 'crates/nu-path/src/pwd_per_drive.rs' to implement a 26-slot
array mapping drive letters to PWDs. Test cases are included in the same
file, along with a doctest for the usage of PWD-per-drive.
2. Modified 'crates/nu-path/src/lib.rs' to declare module of
pwd_per_drive and export struct for PWD-per-drive.
3. Modified 'crates/nu-protocol/src/engine/stack.rs' to sync PWD when
set_cwd() is called. Add PWD-per-drive map as member. Clone between
parent and child. Stub/proxy for nu_path::expand_path_with() to
facilitate filesystem commands using PWD-per-drive.
4. Modified 'crates/nu-cli/src/repl.rs' auto_cd uses PWD-per-drive to
expand path.
5. Modified 'crates/nu-cli/src/completions/completion_common.rs' to
expand relative path when press [TAB] at command line.
6. Modified 'crates/nu-engine/src/env.rs' to collect PWD-per-drive info
as env vars for child process as CMD or PowerShell do, this can let
child process inherit PWD-per-drive info.
7. Modified 'crates/nu-engine/src/eval.rs', caller clone callee's
PWD-per-drive info, supporting 'def --env'
8. Modified 'crates/nu-engine/src/eval_ir.rs', 'def --env' support.
Remove duplicated fn redirect_env()
9. Modified 'src/run.rs', to init PWD-per-drive when startup.
filesystem commands that modified:
1. Modified 'crates/nu-command/src/filesystem/cd.rs', 1 line change to
use stackscoped PWD-per-drive.
Other commands, commit pending....

# 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
# User-Facing Changes
None
# Description
Part 3 of replacing `std::path` types with `nu_path` types added in
#13115. This PR targets the paths listed in `$nu`. That is, the home,
config, data, and cache directories.
# Description
Add `README.md` files to each crate in our workspace (-plugins) and also
include it in the `lib.rs` documentation for <docs.rs> (if there is no
existing `lib.rs` crate documentation)
In all new README I added the defensive comment that the crates are not
considered stable for public consumption. If necessary we can adjust
this if we deem a crate useful for plugin authors.
# Description
This PR adds new types to `nu-path` to enforce path invariants. Namely,
this PR adds:
- `Path` and `PathBuf`. These types are different from, but analogous to
`std::path::Path` and `std::path::PathBuf`.
- `RelativePath` and `RelativePathBuf`. These types must be/contain
strictly relative paths.
- `AbsolutePath` and `AbsolutePathBuf`. These types must be/contain
strictly absolute paths.
- `CanonicalPath` and `CanonicalPathBuf`. These types must be/contain
canonical paths.
Operations are prohibited as necessary to ensure that the invariants of
each type are upheld (needs double-checking).
Only paths that are absolute (or canonical) can be easily used as /
converted to `std::path::Path`s. This is to help force us to account for
the emulated current working directory instead of accidentally using the
current directory of the Nushell process (i.e.,
`std::env::current_dir`). Related to #12975 and #12976.
Note that this PR uses several declarative macros, as the file / this PR
would otherwise be 5000 lines long.
# User-Facing Changes
No major changes yet, just adds types to `nu-path` to be used in the
future.
# After Submitting
Actually use the new path types in all our crates where it makes sense,
removing usages of `std::path` types.
# Description
This PR is an attempt to add a standard location for people to put
completions in. I saw this topic come up again recently and IIRC we
decided to create a standard location. I used the dirs-next crate to
dictate where these locations are. I know some people won't like that
but at least this gets the ball rolling in a direction that has a
standard directory.
This is what the default NU_LIB_DIRS looks like now in the
default_env.nu. It should also be like this when starting nushell with
`nu -n`
```nushell
$env.NU_LIB_DIRS = [
($nu.default-config-dir | path join 'scripts') # add <nushell-config-dir>/scripts
($nu.data-dir | path join 'completions') # default home for nushell completions
]
```
I also added these default folders to the `$nu` variable so now there is
`$nu.data-path` and `$nu.cache-path`.
## Data Dir Default

While I was in there, I also decided to add a cache dir
## Cache Dir Default

### This is what the default looks like in Ubuntu.

### This is what it looks like with XDG_CACHE_HOME and XDG_DATA_HOME
overridden
```nushell
XDG_DATA_HOME=/tmp/data_home XDG_CACHE_HOME=/tmp/cache_home cargo r
```

### This is what the defaults look like in Windows (username scrubbed to
protect the innocent)

How my NU_LIB_DIRS is set in the images above
```nushell
$env.NU_LIB_DIRS = [
($nu.default-config-dir | path join 'scripts') # add <nushell-config-dir>/scripts
'/Users/fdncred/src/nu_scripts'
($nu.config-path | path dirname)
($nu.data-dir | path join 'completions') # default home for nushell completions
]
```
Let the debate begin.

# Description
Fixes#12758.
#12662 introduced a bug where calling `cd` with a path with a trailing
slash would cause `PWD` to be set to a path including a trailing slash,
which is not allowed. This adds a helper to `nu_path` to remove this,
and uses it in the `cd` command to clean it up before setting `PWD`.
# Tests + Formatting
I added some tests to make sure we don't regress on this in the future.
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`
This PR changes `nu_path::expand_path_with()` to no longer remove
trailing slashes. It also fixes bugs in the current implementation due
to ineffective tests (Fixes#12602).

# Description
This allows the following commands to all accept a filename instead of a
plugin name:
- `plugin use`
- `plugin rm`
- `plugin stop`
Slightly complicated because of the need to also check against
`NU_PLUGIN_DIRS`, but I also fixed some issues with that at the same
time

Closes#12103
# 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.

As described in #12103, this PR makes Nushell use `XDG_CONFIG_HOME` as
the config directory if it exists. Otherwise, it uses the old behavior,
which was to use `dirs_next::config_dir()`.
Edit: We discussed choosing between `XDG_CONFIG_HOME` and the default
config directory in Discord and decided against it, at least for now.
<s>@kubouch also suggested letting users choose between
`XDG_CONFIG_HOME` and the default config directory if config files
aren't found on startup and `XDG_CONFIG_HOME` is set to a value
different from the default config directory</s>
On Windows and MacOS, if the `XDG_CONFIG_HOME` variable is set but
`XDG_CONFIG_HOME` is either empty or doesn't exist *and* the old config
directory is non-empty, Nushell will issue a warning on startup saying
that it won't move files from the old config directory to the new one.
To do this, I had to add a `nu_path::config_dir_old()` function. I
assume that at some point, we will remove the warning message and the
function can be removed too. Alternatively, instead of having that
function there, `main.rs` could directly call `dirs_next::config_dir()`.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
When `$env.XDG_CONFIG_HOME` is set to an absolute path, Nushell will use
`$"($env.XDG_CONFIG_HOME)/nushell"` as its config directory (previously,
this only worked on Linux).
To use `App Data\Roaming` (Windows) or `Library/Application Support`
(MacOS) instead (the old behavior), one can either leave
`XDG_CONFIG_HOME` unset or set it to an empty string.
If `XDG_CONFIG_HOME` is set, but to a non-absolute/invalid path, Nushell
will report an error on startup and use the default config directory
instead:

On Windows and MacOS, if the `XDG_CONFIG_HOME` variable is set but
`XDG_CONFIG_HOME` is either empty or doesn't exist *and* the old config
directory is non-empty, Nushell will issue a warning on startup saying
that it won't move files from the old config directory to the new one.

The existing config path tests have been modified to use
`XDG_CONFIG_HOME` to change the config directory on all OSes, not just
Linux.

The documentation will have to be updated to note that Nushell uses
`XDG_CONFIG_HOME` now. As @fdncred pointed out, it's possible for people
to set `XDG_CONFIG_HOME` to, say, `~/.config/nushell` rather than
`~/.config`, so the documentation could warn about that mistake.
