add some completion tests (#12908)
# Description

NO RECORDS FOUND
```

There is a completion issue on previous version, I think @amtoine have
reproduced it before. But currently I can't reproduce it on latest main.
To avoid such regression, I added some tests for completion.

Remove std::env::set_current_dir() call from EngineState::merge_env() (#12922)
As discussed in https://github.com/nushell/nushell/pull/12749, we no
longer need to call `std::env::set_current_dir()` to sync `$env.PWD`
with the actual working directory. This PR removes the call from
`EngineState::merge_env()`.

Refactor the CLI code a bit (#12782)
# Description
Refactors the code in `nu-cli`, `main.rs`, `run.rs`, and few others.
Namely, I added `EngineState::generate_nu_constant` function to
eliminate some duplicate code. Otherwise, I changed a bunch of areas to
return errors instead of calling `std::process::exit`.

# User-Facing Changes
Should be none.

Pass Stack ref to Completer::fetch (#12783)
# Description
Adds an additional `&Stack` parameter to `Completer::fetch` so that the
completers don't have to store a `Stack` themselves. I also removed
unnecessary `EngineState`s from the completers, since the same
`EngineState` is available in the `working_set.permanent_state` also
passed to `Completer::fetch`.

This is a rewrite for some parts of the recursive completion system. The
Rust `std::path` structures often ignores things like a trailing `.`
because for a complete path, it implies the current directory. We are
replacing the use of some of these structs for Strings.

A side effect is the slashes being normalized in Windows. For example if
we were to type `foo/bar/b`, it would complete it to `foo\bar\baz`
because a backward slash is the main separator in windows.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

Relative paths are preserved. `..`s in the paths won't eagerly show
completions from the parent path. For example, `asd/foo/../b` will now
complete to `asd/foo/../bar` instead of `asd/bar`.

Migrate to a new PWD API (#12603)
This is the first PR towards migrating to a new `$env.PWD` API that
returns potentially un-canonicalized paths. Refer to PR #12515 for
motivations.

## New API: `EngineState::cwd()`

The goal of the new API is to cover both parse-time and runtime use
case, and avoid unintentional misuse. It takes an `Option<Stack>` as
argument, which if supplied, will search for `$env.PWD` on the stack in
additional to the engine state. I think with this design, there's less
confusion over parse-time and runtime environments. If you have access
to a stack, just supply it; otherwise supply `None`.

## Deprecation of other PWD-related APIs

Other APIs are re-implemented using `EngineState::cwd()` and properly
documented. They're marked deprecated, but their behavior is unchanged.
Unused APIs are deleted, and code that accesses `$env.PWD` directly
without using an API is rewritten.

Deprecated APIs:

* `EngineState::current_work_dir()`
* `StateWorkingSet::get_cwd()`
* `env::current_dir()`
* `env::current_dir_str()`
* `env::current_dir_const()`
* `env::current_dir_str_const()`

Other changes:

* `EngineState::get_cwd()` (deleted)
* `StateWorkingSet::list_env()` (deleted)
* `repl::do_run_cmd()` (rewritten with `env::current_dir_str()`)

## `cd` and `pwd` now use logical paths by default

This pulls the changes from PR #12515. It's currently somewhat broken
because using non-canonicalized paths exposed a bug in our path
normalization logic (Issue #12602). Once that is fixed, this should
work.

## Future plans

This PR needs some tests. Which test helpers should I use, and where
should I put those tests?

I noticed that unquoted paths are expanded within `eval_filepath()` and
`eval_directory()` before they even reach the `cd` command. This means
every paths is expanded twice. Is this intended?

Once this PR lands, the plan is to review all usages of the deprecated
APIs and migrate them to `EngineState::cwd()`. In the meantime, these
usages are annotated with `#[allow(deprecated)]` to avoid breaking CI.

Remove the Value::Block case (#12582)
# Description
`Value` describes the types of first-class values that users and scripts
can create, manipulate, pass around, and store. However, `Block`s are
not first-class values in the language, so this PR removes it from
`Value`. This removes some unnecessary code, and this change should be
invisible to the user except for the change to `scope modules` described
below.

# User-Facing Changes
Breaking change: the output of `scope modules` was changed so that
`env_block` is now `has_env_block` which is a boolean value instead of a
`Block`.

# After Submitting
Update the language guide possibly.

Add command_prelude module (#12291)
# Description
When implementing a `Command`, one must also import all the types
present in the function signatures for `Command`. This makes it so that
we often import the same set of types in each command implementation
file. E.g., something like this:
```rust
use nu_protocol::ast::Call;
use nu_protocol::engine::{Command, EngineState, Stack};
use nu_protocol::{
    record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, PipelineData,
    ShellError, Signature, Span, Type, Value,
};
```

This PR adds the `nu_engine::command_prelude` module which contains the
necessary and commonly used types to implement a `Command`:
```rust
// command_prelude.rs
pub use crate::CallExt;
pub use nu_protocol::{
    ast::{Call, CellPath},
    engine::{Command, EngineState, Stack},
    record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, IntoSpanned,
    PipelineData, Record, ShellError, Signature, Span, Spanned, SyntaxShape, Type, Value,
};
```

This should reduce the boilerplate needed to implement a command and
also gives us a place to track the breadth of the `Command` API. I tried
to be conservative with what went into the prelude modules, since it
might be hard/annoying to remove items from the prelude in the future.
Let me know if something should be included or excluded.

IO and redirection overhaul (#11934)
# Description
The PR overhauls how IO redirection is handled, allowing more explicit
and fine-grain control over `stdout` and `stderr` output as well as more
efficient IO and piping.

To summarize the changes in this PR:
- Added a new `IoStream` type to indicate the intended destination for a
pipeline element's `stdout` and `stderr`.
- The `stdout` and `stderr` `IoStream`s are stored in the `Stack` and to
avoid adding 6 additional arguments to every eval function and
`Command::run`. The `stdout` and `stderr` streams can be temporarily
overwritten through functions on `Stack` and these functions will return
a guard that restores the original `stdout` and `stderr` when dropped.
- In the AST, redirections are now directly part of a `PipelineElement`
as a `Option<Redirection>` field instead of having multiple different
`PipelineElement` enum variants for each kind of redirection. This
required changes to the parser, mainly in `lite_parser.rs`.
- `Command`s can also set a `IoStream` override/redirection which will
apply to the previous command in the pipeline. This is used, for
example, in `ignore` to allow the previous external command to have its
stdout redirected to `Stdio::null()` at spawn time. In contrast, the
current implementation has to create an os pipe and manually consume the
output on nushell's side. File and pipe redirections (`o>`, `e>`, `e>|`,
etc.) have precedence over overrides from commands.

This PR improves piping and IO speed, partially addressing #10763. Using
the `throughput` command from that issue, this PR gives the following
speedup on my setup for the commands below:
| Command | Before (MB/s) | After (MB/s) | Bash (MB/s) |
| --------------------------- | -------------:| ------------:|
-----------:|
| `throughput o> /dev/null` | 1169 | 52938 | 54305 |
| `throughput \| ignore` | 840 | 55438 | N/A |
| `throughput \| null` | Error | 53617 | N/A |
| `throughput \| rg 'x'` | 1165 | 3049 | 3736 |
| `(throughput) \| rg 'x'` | 810 | 3085 | 3815 |

(Numbers above are the median samples for throughput)

This PR also paves the way to refactor our `ExternalStream` handling in
the various commands. For example, this PR already fixes the following
code:
```nushell
^sh -c 'echo -n "hello "; sleep 0; echo "world"' | find "hello world"
```
This returns an empty list on 0.90.1 and returns a highlighted "hello
world" on this PR.

Since the `stdout` and `stderr` `IoStream`s are available to commands
when they are run, then this unlocks the potential for more convenient
behavior. E.g., the `find` command can disable its ansi highlighting if
it detects that the output `IoStream` is not the terminal. Knowing the
output streams will also allow background job output to be redirected
more easily and efficiently.

# User-Facing Changes
- External commands returned from closures will be collected (in most
cases):
  ```nushell
  1..2 | each {|_| nu -c "print a" }
  ```
This gives `["a", "a"]` on this PR, whereas this used to print "a\na\n"
and then return an empty list.

  ```nushell
  1..2 | each {|_| nu -c "print -e a" }
  ```
This gives `["", ""]` and prints "a\na\n" to stderr, whereas this used
to return an empty list and print "a\na\n" to stderr.

- Trailing new lines are always trimmed for external commands when
piping into internal commands or collecting it as a value. (Failure to
decode the output as utf-8 will keep the trailing newline for the last
binary value.) In the current nushell version, the following three code
snippets differ only in parenthesis placement, but they all also have
different outputs:

  1. `1..2 | each { ^echo a }`
     ```
     a
     a
     ╭────────────╮
     │ empty list │
     ╰────────────╯
     ```
  2. `1..2 | each { (^echo a) }`
     ```
     ╭───┬───╮
     │ 0 │ a │
     │ 1 │ a │
     ╰───┴───╯
     ```
  3. `1..2 | (each { ^echo a })`
     ```
     ╭───┬───╮
     │ 0 │ a │
     │   │   │
     │ 1 │ a │
     │   │   │
     ╰───┴───╯
     ```

  But in this PR, the above snippets will all have the same output:
  ```
  ╭───┬───╮
  │ 0 │ a │
  │ 1 │ a │
  ╰───┴───╯
  ```

- All existing flags on `run-external` are now deprecated.

- File redirections now apply to all commands inside a code block:
  ```nushell
  (nu -c "print -e a"; nu -c "print -e b") e> test.out
  ```
This gives "a\nb\n" in `test.out` and prints nothing. The same result
would happen when printing to stdout and using a `o>` file redirection.

- External command output will (almost) never be ignored, and ignoring
output must be explicit now:
  ```nushell
  (^echo a; ^echo b)
  ```
This prints "a\nb\n", whereas this used to print only "b\n". This only
applies to external commands; values and internal commands not in return
position will not print anything (e.g., `(echo a; echo b)` still only
prints "b").

- `complete` now always captures stderr (`do` is not necessary).

The language guide and other documentation will need to be updated.

This PR adds a new evaluator path with callbacks to a mutable trait
object implementing a Debugger trait. The trait object can do anything,
e.g., profiling, code coverage, step debugging. Currently,
entering/leaving a block and a pipeline element is marked with
callbacks, but more callbacks can be added as necessary. Not all
callbacks need to be used by all debuggers; unused ones are simply empty
calls. A simple profiler is implemented as a proof of concept.

The debugging support is implementing by making `eval_xxx()` functions
generic depending on whether we're debugging or not. This has zero
computational overhead, but makes the binary slightly larger (see
benchmarks below). `eval_xxx()` variants called from commands (like
`eval_block_with_early_return()` in `each`) are chosen with a dynamic
dispatch for two reasons: to not grow the binary size due to duplicating
the code of many commands, and for the fact that it isn't possible
because it would make Command trait objects object-unsafe.

In the future, I hope it will be possible to allow plugin callbacks such
that users would be able to implement their profiler plugins instead of
having to recompile Nushell.
[DAP](https://microsoft.github.io/debug-adapter-protocol/) would also be
interesting to explore.

Try `help debug profile`.

## Screenshots

Basic output:

![profiler_new](https://github.com/nushell/nushell/assets/25571562/418b9df0-b659-4dcb-b023-2d5fcef2c865)

To profile with more granularity, increase the profiler depth (you'll
see that repeated `is-windows` calls take a large chunk of total time,
making it a good candidate for optimizing):

![profiler_new_m3](https://github.com/nushell/nushell/assets/25571562/636d756d-5d56-460c-a372-14716f65f37f)

## Benchmarks

### Binary size

Binary size increase vs. main: **+40360 bytes**. _(Both built with
`--release --features=extra,dataframe`.)_

### Time

```nushell
# bench_debug.nu
use std bench

let test = {
    1..100
    | each {
        ls | each {|row| $row.name | str length }
    }
    | flatten
    | math avg
}

print 'debug:'
let res2 = bench { debug profile $test } --pretty
print $res2
```

```nushell
# bench_nodebug.nu
use std bench

let test = {
    1..100
    | each {
        ls | each {|row| $row.name | str length }
    }
    | flatten
    | math avg
}

print 'no debug:'
let res1 = bench { do $test } --pretty
print $res1
```

`cargo run --release -- bench_debug.nu` is consistently 1--2 ms slower
than `cargo run --release -- bench_nodebug.nu` due to the collection
overhead + gathering the report. This is expected. When gathering more
stuff, the overhead is obviously higher.

`cargo run --release -- bench_nodebug.nu` vs. `nu bench_nodebug.nu` I
didn't measure any difference. Both benchmarks report times between 97
and 103 ms randomly, without one being consistently higher than the
other. This suggests that at least in this particular case, when not
running any debugger, there is no runtime overhead.

## API changes

This PR adds a generic parameter to all `eval_xxx` functions that forces
you to specify whether you use the debugger. You can resolve it in two
ways:
* Use a provided helper that will figure it out for you. If you wanted
to use `eval_block(&engine_state, ...)`, call `let eval_block =
get_eval_block(&engine_state); eval_block(&engine_state, ...)`
* If you know you're in an evaluation path that doesn't need debugger
support, call `eval_block::<WithoutDebug>(&engine_state, ...)` (this is
the case of hooks, for example).

I tried to add more explanation in the docstring of `debugger_trait.rs`.

## TODO

- [x] Better profiler output to reduce spam of iterative commands like
`each`
- [x] Resolve `TODO: DEBUG` comments
- [x] Resolve unwraps
- [x] Add doc comments
- [x] Add usage and extra usage for `debug profile`, explaining all
columns

Fix completions for directories with hidden files (#11921)
# Description
Attempting to complete a directory with hidden files could cause a
variety of issues. When Rust parses the partial path to be completed
into components, it removes the trailing `.` since it interprets this to
mean "the current directory", but in the case of the completer we
actually want to treat the trailling `.` as a literal `.`. This PR fixes
this by adding a `.` back into the Path components if the last character
of the path is a `.` AND the path is longer than 1 character (eg., not
just a ".", since that correctly gets interpreted as Component::CurDir).

Here are some things this fixes:
- Panic when tab completing for hidden files in a directory with hidden
files (ex. `ls test/.`)
- Panic when tab completing a directory with only hidden files (since
the common prefix ends with a `.`, causing the previous issue)
- Mishandling of tab completing hidden files in directory (ex. `ls
~/.<TAB>` lists all files instead of just hidden files)
- Trailing `.` being inexplicably removed when tab completing a
directory without hidden files

While testing for this PR I also noticed there is a similar issue when
completing with `..` (ex. `ls ~/test/..<TAB>`) which is not fixed by
this PR (edit: see #11922).

Fix file completions which contains glob pattern (#11766)
# Description
Fixes: https://github.com/nushell/nushell/issues/11762

The auto-completion is somehow annoying if a path contains a glob
pattern, let's say if user type `ls` and it auto-completes to <code>ls
`[a] bc.txt`</code>, and user can't list the file because it's backtick
quoted.

This pr is going to fix it.

Refactor and fix Config<->Value mechanism (#10896)
# Description
Our config exists both as a `Config` struct for internal consumption and
as a `Value`. The latter is exposed through `$env.config` and can be
both set and read.
Thus we have a complex bug-prone mechanism, that reads a `Value` and
then tries to plug anything where the value is unrepresentable in
`Config` with the correct state from `Config`.

The parsing involves therefore mutation of the `Value` in a nested
`Record` structure. Previously this was wholy done manually, with
indices.
To enable deletion for example, things had to be iterated over from the
back. Also things were indexed in a bunch of places. This was hard to
read and an invitation for bugs.

With #10876 we can now use `Record::retain_mut` to traverse the records,
modify anything that needs fixing, and drop invalid fields.

# Parts:

- Error messages now consistently use the correct spans pointing to the
problematic value and the paths displayed in some messages are also
aligned with the keys used for lookup.
- Reconstruction of values has been fixed for:
	- `table.padding`
	- `buffer_editor`
	- `hooks.command_not_found`
	- `datetime_format` (partial solution)
- Fix validation of `table.padding` input so value is not set (and
underflows `usize` causing `table` to run forever with negative values)
- New proper types for settings. Fully validated enums instead of
strings:
  - `config.edit_mode` -> `EditMode` 
  	- Don't fall back to vi-mode on invalid string
  - `config.table.mode` -> `TableMode`
- there is still a fall back to `rounded` if given an invalid
`TableMode` as argument to the `nu` binary
  - `config.completions.algorithm` -> `CompletionAlgorithm`
  - `config.error_style` -> `ErrorStyle`
    - don't implicitly fall back to `fancy` when given an invalid value.
- This should also shrink the size of `Config` as instead of 4x24 bytes
those fields now need only 4x1 bytes in `Config`
- Completely removed macros relying on the scope of `Value::into_config`
so we can break it up into smaller parts in the future.
- Factored everything into smaller files with the types and helpers for
particular topics.
- `NuCursorShape` now explicitly expresses the `Inherit` setting.
conversion to option only happens at the interface to `reedline`

Move Value to helpers, separate span call (#10121)
# Description

As part of the refactor to split spans off of Value, this moves to using
helper functions to create values, and using `.span()` instead of
matching span out of Value directly.

Hoping to get a few more helping hands to finish this, as there are a
lot of commands to update :)

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`"

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
```

This is a pretty heavy refactor of the parser to support multiple parser
errors. It has a few issues we should address before landing:

- [x] In some cases, error quality has gotten worse `1 / "bob"` for

- [x] if/else isn't currently parsing correctly
- probably others

FEATURE: add the startup time to $nu (#8353)
# Description
in https://github.com/nushell/nushell/issues/8311 and the discord
server, the idea of moving the default banner from the `rust` source to
the `nushell` standar library has emerged 😋

however, in order to do this, one need to have access to all the
variables used in the default banner => all of them are accessible
because known constants, except for the startup time of the shell, which
is not anywhere in the shell...

#### this PR adds exactly this, i.e. the new `startup_time` to the `$nu`
variable, which is computed to have the exact same value as the value
shown in the banner.

## the changes
in order to achieve this, i had to
- add `startup_time` as an `i64` to the `EngineState` => this is, to the
best of my knowledge, the easiest way to pass such an information around
down to where the banner startup time is computed and where the `$nu`
variable is evaluated
- add `startup-time` to the `$nu` variable and use the `EngineState`
getter for `startup_time` to show it as a `Value::Duration`
- pass `engine_state` as a `&mut`able argument from `main.rs` down to
`repl.rs` to allow the setter to change the value of `startup_time` =>
without this, the value would not change and would show `-1ns` as the
default value...
- the value of the startup time is computed in `evaluate_repl` in
`repl.rs`, only once at the beginning, and the same value is used in the
default banner 👌

# User-Facing Changes
one can now access to the same time as shown in the default banner with
```bash
$nu.startup-time
```

# Tests + Formatting
- 🟢 `cargo fmt --all`
- 🟢 `cargo clippy --workspace -- -D warnings -D

Add is-interactive and is-login to NuVariable and allow running scripts with -i (#8306)
Add two rows in `$nu`, `$nu.is-interactive` and `$nu.is-login`, which
are true when nu is run in interactive and login mode respectively.

The `-i` flag now behaves a bit more like that of bash's, where the any
provided command or file is run without REPL but in "interactive mode".
This should entail sourcing interactive-mode config files, but since we
are planning on overhauling the config system soon, I'm holding off on
that. For now, all `-i` does is set `$nu.is-interactive` to be true.

About testing, I can't seem to find where cli-args get tested, so I
haven't written any new tests for this. Also I don't think there are any
docs that need updating. However if I'm wrong please tell me.

files and directory completions now use ascending ordering rather than Levenshtein. #8023 (#8085)
# Description

This change sorts completions for files and directories by the ascending
ordering method, related to issue:
[#8023](https://github.com/nushell/nushell/issues/8023)

Currently the Suggestions are being sorted twice, so it's now following
the convention from `completion/base.rs` to match on the
`self.get_sort_by()` result.

# User-Facing Changes

Previously the suggestions were being sorted by the Levenshtein method:
```
/home/rdevenney/projects/open_source/nushell| cd
src/                wix/                docs/               tests/
assets/             crates/             docker/             images/
target/             benches/            pkg_mgrs/           .git/
.cargo/             .github/
```

Now when you tab for autocompletions, they show up in ascending
alphabetical order as shown below (with hidden files/folders at the
end).
```
/home/rdevenney/projects/open_source/nushell| cd
assets/             benches/            crates/             docker/
docs/               images/             pkg_mgrs/           src/
target/             tests/              wix/                .cargo/
.git/               .github/
```

And when you've already typed a bit of the path:

Revert #7779 (enables back subcommand completions) (#8102)
# Description

Reverts the PR #7779 which breaks subcommand completions. The issues
#7648 and #7754 thus still need fixing.

This reverts commit 8acced5.

# User-Facing Changes

Unfortunately, also brings back the completion panic if alias is shorter
than the command name.

fix completions PATH vs Path (#8003)
# Description

This PR attempts to fix the completions issue where, on Windows,
completions wouldn't get generated from items in your path environment
variable. This seemed to be down to `PATH` vs `Path`. So, I tried to add
a new function that we can use anywhere to avoid this problem.

Add 'number' command for enumeration (#7871)
# Description

This adds a `number` command that will enumerate the input, and add an
`index` and `item` record for each item. The `index` is the number of
the item in the input stream, and `item` is the original value of the
item.

```
> ls | number | get 14
╭───────┬────────────────────────────╮
│ index │ 14                         │
│       │ ╭──────────┬─────────────╮ │

add --mime-type(-m) to ls in the type column (#7616)
# Description

This PR adds the `mime-type` to the `type` column if you add the
`--mime-type(-m)` flag to `ls`.
<img width="853" alt="Screenshot 2022-12-27 at 11 43 20 AM"
src="https://user-images.githubusercontent.com/343840/209705499-27fe40fe-0356-4d9d-97f2-4b2dc52e0963.png">

# User-Facing Changes

If you specify the `-m` flag, you get the "guessed at" mime type. The
guess is based on the file name and uses this crate
https://docs.rs/mime_guess/latest/mime_guess/ for the guessing.

Part of issue #7612 and and #7524

There's some debate on if the `mime-type` should be added to the `type`
column or if there should be a separate `mime` column. I tend to lean on
the side of `type` since it's technically a type and it's only in that
column if you ask it to be there. Also, I'd prefer to reuse a column
rather than having a list of sprawling columns. Also, as @KodiCraft
suggested, there is precedence as with `ls -d` where the summed size is
in the size column.

I could go either way and if someone wants to create a `mime` column,
we'd probably accept it.

Protocol: debug_assert!() Span to reflect a valid slice (#6806)
Also enforce this by #[non_exhaustive] span such that going forward we
cannot, in debug builds (1), construct invalid spans.

The motivation for this stems from #6431 where I've seen crashes due to
invalid slice indexing.

My hope is this will mitigate such senarios

nu-cli: merge completions tests into one file (#6389)

The reason for them to be separated was organization, so we wouldn't need to scroll a huge file.
But that came with another issue, because rust generates a new binary for each completion test file and each completion test depends on Nu looks like all the dataframes were coming into each test file as well (as pointed by @rgwood

* Copy completion filter to custom completions

* Remove filter function from completer

This function was a no-op for FileCompletion and CommandCompletion.
Flag- and VariableCompletion just filters with `starts_with` which
happens in both completers anyway and should therefore also be a no-op.
The remaining use case in CustomCompletion was moved into the
CustomCompletion source file.

Filtering should probably happen immediately while fetching completions
to avoid unnecessary memory allocations.

Obey precedence rules in which; Fix #2875 (#2885)
* Obay precedence rules in which; Fix #2875

Before which did not obay the precedence of alias before def commands.
Furthermore, `which -a echo` would only report either an alias or a def command or an
internal command with the provided name. Not all.

With this commit applied its fixed :)

Example:
```shell
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> def echo [] {^echo hi}
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> echo
hi
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> which -a echo
───┬──────┬──────────────────────────┬─────────
 # │ arg  │           path           │ builtin
───┼──────┼──────────────────────────┼─────────
 0 │ echo │ Nushell custom command   │ No
 1 │ echo │ Nushell built-in command │ Yes
 2 │ echo │ /usr/bin/echo            │ No
───┴──────┴──────────────────────────┴─────────
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> alias echo = ^echo hi there
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> echo
hi there
/home/leo/repos/nushell(fix/which_reports_wrong_usage)> which -a echo
───┬──────┬──────────────────────────┬─────────
 # │ arg  │           path           │ builtin
───┼──────┼──────────────────────────┼─────────
 0 │ echo │ Nushell alias            │ No
 1 │ echo │ Nushell custom command   │ No
 2 │ echo │ Nushell built-in command │ Yes
 3 │ echo │ /usr/bin/echo            │ No
───┴──────┴──────────────────────────┴─────────

Add comments to next LiteCommand (#2846)
This commit applied adds comments preceding a command to the LiteCommands new
field `comments`.

This can be usefull for example when defining a function with `def`. Nushell
could pick up the comments and display them when the user types `help my_def_func`.

Example
```shell
def my_echo [arg] { echo $arg }
```
The LiteCommand def will now contain the comments `My echo` and `It's much
better :)`.

The comment is not associated with the next command if there is a (or multiple) newline
between them.
Example
```shell

echo 42
```

This new functionality is similar to DocStrings. One might introduce a special
notation for such DocStrings, so that the parser can differentiate better
between discardable comments and usefull documentation.

Path Command Enhancement Project (#2742)
* Add string argument support for path subcommands

* Add --replace option to 'path extension' command

* Add examples of replacing for path extension

* Refactor path extension and its example

* Add replacement functionality to path basename

* Refactor path subcommands to support more args

This adds a lot of redundancy to non-relevant subcommands such as type,
exists or expand.

* Add replace and num_levels options to path dirname

* Rename num_levels option to num-levels

* Remove commented code

* Clean up path basename

* Fix path dirname description

* Add path filestem opts; Rename extension -> suffix

* Add prefix option and examples to path filestem

* Fix broken num-levels of path dirname

* Fix failing example test of path filestem

* Fix failing test of path extension

* Formatting

* Add Windows-specific path subcommand examples

`path expand` is still broken but otherwise seems to fix all examples
on Windows

* Fix weird path expand on Windows

Also disable example tests for path expand. Failed caconicalization
(e.g., due to path not existing) returns the original path so the
examples always fail.

* Formatting

* Return path datatype when appropriate

* Do not append empty remainder to path dirname

* Add tests for path subcommands

* Formatting

* Revisit path subcommand description strings

* Apply clippy suggestions; Formatting

* Remove problematic test checking '~' expansion

Wouldn't run on minimal due to useing optional dependency.
The test success was also deending on the presence of home dir on the
testing machine which might not be completely robust.

* Add missing newline to file

* Remove commented code

* Fix typo

* Change comment to be more informative

* Make match statement to lookup in table

* Remove resolved question

https://github.com/nushell/nushell/pull/2685#discussion_r509832054

* Pick ...or_insert_dependency functions into pieces

Previously there was get_shape_of_expr_or_insert dependency, now there is
get_shape_of_expr and get_shape_of_expr_or_insert_dependency

2 new functions have been added: get_result_shape_of_math_expr and
get_result_shape_of_math_expr_or_insert_dependency

* Remove flattening of deep binary expressions

Previously deep binary expressions have been flattened through the insertion of
fake vars. This logic was quite complicated. Now if a variable depends on the
result shape of a binary expression and the result shape can't be computed,
the variable simply depends on the whole binary.

* Change Expression::Variable(Variable::It(...)) to Expression::Variable(...)

* Simplify get_result_shapes_in_math_expr

* Simplify infer_shapes_in_binary_expr

* Clarify comment

* Clarify comment

* Fix clippy lint

* Move check for real var into checked_insert
