Add IDE support (#8745)
# Description

This adds a set of new flags on the `nu` binary intended for use in
IDEs. Here is the set of supported functionality so far:

* goto-def - go to the definition of a variable or custom command
* type hints - see the inferred type of variables
* check - see the errors in the document (currently only one error is
supported)
* hover - get information about the variable or custom command
* complete - get a completion list at the current position

# User-Facing Changes

No changes to the REPL experience. This only impacts the IDE scenario.

# 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-utils/standard_library/tests.nu` to run the
tests for the standard library

Remove -t/--threads flag from nu (#8686)
### What?

This PR removes the `--threads` flag from nu.exe:


![image](https://user-images.githubusercontent.com/26268125/229021408-bf78ce64-11f7-4354-a410-ed905b96bb5a.png)

### Why?

Darren added a `--threads` flag to `par-each` in
https://github.com/nushell/nushell/pull/8679, so it no longer respects
the global `--threads` flag. Now the only place `rayon` is used is [the
`table`
renderer](3db0aed9f7/crates/nu-command/src/viewers/table.rs (L15)).

I don't think anyone will actually want to specify the number of threads
used in `table`, and it would be confusing to leave this flag around
when it no longer does anything useful.

### Notes

Relevant `rayon` docs:

fix test_default_config_path test after pr 8653 (#8690)
# Description

This PR fixes a testing bug that @rgwood found and PR #8653 introduced,
mentioned
[here](https://github.com/nushell/nushell/pull/8653#issuecomment-1491263657).
Since 8653 returns canonicalizes config paths now, the tests need to
return canonicalized paths as well. Without this PR, if you have your
nushell config dir symlinked, this test will fail. This PR fixes that
test.

move 'str substring' to only use ranges (#8660)
# Description

This removes all the old style of quasi-ranges before we had full range
support from `str substring`. Functionality should otherwise work, but
only with the official range syntax.

Removes the array and string forms of ranges from `str substring`.
Leaves only the official range support for range values.

Improve inferred record types and type compat (#8649)
# Description

This allows for type inference to infer record types in more cases. The
only time we will now fall back to `Any` is when one of the fields has a
computed value.

I also updated the type mismatch error and highlighting to be in-line
with other errors.

# User-Facing Changes

This may result in stricter type checking. Previously `{}` had the
inferred type `Any` but will now have the correct inferred type of
`Record<>`.

Change comparison operators to allow nulls (#8617)
Prior to this PR, the less/greater than operators (`<`, `>`, `<=`, `>=`)
would throw an error if either side was null. After this PR, these
operators return null if either side (or both) is null.

### Examples
```bash 
1 < 3       # true
1 < null    # null
null < 3    # null
null < null # null
```

### Motivation

JT [asked the C#
folks](https://discord.com/channels/601130461678272522/615329862395101194/1086137515053957140)
and this is apparently the approach they would choose for comparison
operators if they could start from scratch.

This PR makes `where` more convenient to use on jagged/missing data. For
example, we can now filter on columns that may not be present in every
row:
```
> [{foo: 123} {}] | where foo? > 10
╭───┬─────╮
│ # │ foo │
├───┼─────┤
│ 0 │ 123 │
╰───┴─────╯

another issue.

innitially, this was accepted by the parser
```nu

```

but now an error is raised
```nu

allow lists to have type annotations (#8529)
this pr refines #8270 and closes #8109

# description
examples:

the original syntax is okay
```nu
def okay [nums: list] {}         # the type of list will be list<any>
```

empty annotations are allowed in any variation
the last two may be caught by a future formatter, 
but do not affect `nu` code currently
```nu
def okay [nums: list<>] {}       # okay

def okay [nums: list<     >] {}  # weird but also okay

def okay [nums: list<
>] {}                            # also weird but okay
```

types are allowed (See [notes](#notes) below)
```nu
def okay [nums: list<int>] {}    # `test [a b c]` will throw an error 

def okay [nums: list< int > {}   # any amount of space within the angle brackets is okay

def err [nums: list <int>] {}    # this is not okay, `nums` and `<int>` will be parsed as
                                 # two separate params, 
```

nested annotations are allowed in many variations
```nu
def okay [items: list<list<int>>] {}

def okay [items: list<list>] {}
```

any unterminated annotation is caught
```nu
Error: nu::parser::unexpected_eof

  × Unexpected end of code.

```

unknown types are flagged
```nu

  × Unknown type.

   ·                     ─┬─

# notes
the error message for mismatched types in not as intuitive
```nu
Error: nu::parser::parse_mismatch

  × Parse mismatch during operation.
   ╭─[source:1:1]

   ·                                    ╰── expected int

it should be something like this
```nu

  × Parse mismatch during operation.
   ╭─[source:1:1]

Cell paths: make optional path members short-circuit (#8554)
This is a follow-up to https://github.com/nushell/nushell/pull/8379 and
https://github.com/nushell/nushell/discussions/8502.

This PR makes it so that the new `?` syntax for marking a path member as
optional short-circuits, as voted on in the
[8502](https://github.com/nushell/nushell/discussions/8502) poll.
Previously, `{ foo: 123 }.bar?.baz` would raise an error:

```
> { foo: 123 }.bar?.baz
  × Data cannot be accessed with a cell path
   ╭─[entry #15:1:1]
 1 │ { foo: 123 }.bar?.baz
   ·                   ─┬─
   ·                    ╰── nothing doesn't support cell paths
   ╰────
   ```

Here's what was happening:

1. The `bar?` path member access returns `nothing` because there is no field named `bar` on the record
2. The `baz` path member access fails when trying to access a `baz` field on that `nothing` value

After this change, `{ foo: 123 }.bar?.baz` returns `nothing`; the failed `bar?` access immediately returns `nothing` and the `baz` access never runs.

feat: add a command_not_found hook (#8314)
# Description
Add a `command_not_found` function to `$env.config.hooks`. If this
function outputs a string, then it's included in the `help`.

binary, looks like:

```nushell
let-env config = {
  # ...
  hooks: {
    command_not_found: {
      |cmd_name| (
        try {
          let pkgs = (pkgfile --binaries --verbose $cmd_name)
          (
            $"(ansi $env.config.color_config.shape_external)($cmd_name)(ansi reset) " +
            $"may be found in the following packages:\n($pkgs)"
          )
        } catch {
          null
        }

Restrict closure expression to be something like {|| ...} (#8290)
# Description

As title, closes: #7921 closes: #8273

# User-Facing Changes

when define a closure without pipe, nushell will raise error for now:
```
❯ let x = {ss ss}
Error: nu::parser::closure_missing_pipe

  × Missing || inside closure
   ╭─[entry #2:1:1]
 1 │ let x = {ss ss}
   ·         ───┬───
   ·            ╰── Parsing as a closure, but || is missing
   ╰────
  help: Try add || to the beginning of closure
```

`any`, `each`, `all`, `where` command accepts closure, it forces user
input closure like `{||`, or parse error will returned.
```
❯ {major:2, minor:1, patch:4} | values | each { into string }
Error: nu::parser::closure_missing_pipe

  × Missing || inside closure
   ╭─[entry #4:1:1]

   ╰────
  help: Try add || to the beginning of closure
```

`with-env`, `do`, `def`, `try` are special, they still remain the same,
although it says that it accepts a closure, but they don't need to be
written like `{||`, it's more likely a block but can capture variable
outside of scope:
```
❯ def test [input] { echo [0 1 2] | do { do { echo $input } } }; test aaa
aaa
```

Just realize that It's a big breaking change, we need to update config
and scripts...

parser: Add cell path literal syntax (#8493)
# Description

This adds a new cell path literal syntax for use in any value position,
not just in a context where we expect a cell path.

This can be used to assign to a variable and then later use that
variable as a cell path.

Example:
```
> let cell_path = $.a.b
> {a: {b: 3}} | get $cell_path
3
```
# User-Facing Changes

This adds the syntax `$.a.b` to universally mean the cell path `a.b`,
even in a context that doesn't expect a cell path.

fix: fix commandline when called with no arguments (#8207)
# Description

This fixes the `commandline` command when it's run with no arguments, so
it outputs the command being run. New line characters are included.

This allows for:

- [A way to get current command inside pre_execution hook · Issue #6264
· nushell/nushell](https://github.com/nushell/nushell/issues/6264)
- The possibility of *Atuin* to work work *Nushell*. *Atuin* hooks need
to know the current repl input before it is run.

Optional members in cell paths: Attempt 2 (#8379)
This is a follow up from https://github.com/nushell/nushell/pull/7540.
Please provide feedback if you have the time!

## Summary

This PR lets you use `?` to indicate that a member in a cell path is
optional and Nushell should return `null` if that member cannot be
accessed.

Unlike the previous PR, `?` is now a _postfix_ modifier for cell path
members. A cell path of `.foo?.bar` means that `foo` is optional and
`bar` is not.

`?` does _not_ suppress all errors; it is intended to help in situations
where data has "holes", i.e. the data types are correct but something is
missing. Type mismatches (like trying to do a string path access on a
date) will still fail.

### Record Examples

```bash

{ foo: 123 }.foo # returns 123

{ foo: 123 }.bar # errors
{ foo: 123 }.bar? # returns null

{ foo: 123 } | get bar # errors
{ foo: 123 } | get bar? # returns null

{ foo: 123 }.bar.baz # errors
{ foo: 123 }.bar?.baz # errors because `baz` is not present on the result from `bar?`
{ foo: 123 }.bar.baz? # errors
{ foo: 123 }.bar?.baz? # returns null
```

### List Examples
```

╭───┬─────╮
│ # │ foo │

╰───┴─────╯
```

# Breaking changes

1. Column names with `?` in them now need to be quoted.
2. The `-i`/`--ignore-errors` flag has been removed from `get` and
`select`
1. After this PR, most `get` error handling can be done with `?` and/or
`try`/`catch`.
4. Cell path accesses like this no longer work without a `?`:
```bash
〉[{a:1 b:2} {a:3}].b.0
2
```
We had some clever code that was able to recognize that since we only
want row `0`, it's OK if other rows are missing column `b`. I removed
that because it's tricky to maintain, and now that query needs to be
written like:


```bash
〉[{a:1 b:2} {a:3}].b?.0
2
```

I think the regression is acceptable for now. I plan to do more work in
the future to enable streaming of cell path accesses, and when that
happens I'll be able to make `.b.0` work again.

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
```

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.

Cratification: Test Infrastructure Support Part One (#8335)
startup nushell with no config file or env file...


This PR gives the ability to start up nushell easily with no config or
env config files
simply by passing in

```rust
nu -n
```

or

```rust
nu --no-config-file
```

A bonus is that startup times for nushell decreases FIVE fold...
From about > 50ms to less than < 10ms on average on my mac

This will enable Part II which will hopefully be the ability to
to send this flag into the nu! macro and turn off loading of the config
files...

Remember when config files are enabled the nu-cmd-lang tests fail
because the
commands in the config files are a superset of the commands in
nu-cmd-lang...

In my preliminary tests before by zeroing out the config files the
nu-cmd-lang tests passed...

Independent of the cratification efforts I have always wanted a way
anyway to turn off loading
the config files when starting up nushell... So this accomplishes that
task...

Document and critically review ShellError variants - Ep. 2 (#8326)
Continuation of #8229 

# Description

The `ShellError` enum at the moment is kind of messy. 

Many variants are basic tuple structs where you always have to reference
the implementation with its macro invocation to know which field serves
which purpose.
Furthermore we have both variants that are kind of redundant or either
overly broad to be useful for the user to match on or overly specific
with few uses.

So I set out to start fixing the lacking documentation and naming to
make it feasible to critically review the individual usages and fix
those.
Furthermore we can decide to join or split up variants that don't seem
to be fit for purpose.

**Everyone:** Feel free to add review comments if you spot inconsistent
use of `ShellError` variants.

- Name fields of `SE::IncorrectValue`
- Merge and name fields on `SE::TypeMismatch`
- Name fields on `SE::UnsupportedOperator`
- Name fields on `AssignmentRequires*` and fix doc
- Name fields on `SE::UnknownOperator`
- Name fields on `SE::MissingParameter`
- Name fields on `SE::DelimiterError`
- Name fields on `SE::IncompatibleParametersSingle`

Re-implement aliases (#8123)
# Description

This PR adds an alternative alias implementation. Old aliases still work
but you need to use `old-alias` instead of `alias`.

Instead of replacing spans in the original code and re-parsing, which
proved to be extremely error-prone and a constant source of panics, the
new implementation creates a new command that references the old
command. Consider the new alias defined as `alias ll = ls -l`. The
parser creates a new command called `ll` and remembers that it is
actually a `ls` command called with the `-l` flag. Then, when the parser
sees the `ll` command, it will translate it to `ls -l` and passes to it
any parameters that were passed to the call to `ll`. It works quite
similar to how known externals defined with `extern` are implemented.

The new alias implementation should work the same way as the old
aliases, including exporting from modules, referencing both known and
unknown externals. It seems to preserve custom completions and pipeline
metadata. It is quite robust in most cases but there are some rough
edges (see later).

Fixes https://github.com/nushell/nushell/issues/7648,
https://github.com/nushell/nushell/issues/8026,
https://github.com/nushell/nushell/issues/7512,

https://github.com/nushell/nushell/issues/7754

No effect: https://github.com/nushell/nushell/issues/8122 (we might
revisit the completions code after this PR)

Should use custom command instead:
https://github.com/nushell/nushell/issues/6048

# User-Facing Changes

Since aliases are now basically commands, it has some new implications:

1. `alias spam = "spam"` (requires command call)
	* **workaround**: use `alias spam = echo "spam"`
2. `def foo [] { 'foo' }; alias foo = ls -l` (foo defined more than
once)
* **workaround**: use different name (commands also have this
limitation)
4. `alias ls = (ls | sort-by type name -i)`
* **workaround**: Use custom command. _The common issue with this is
that it is currently not easy to pass flags through custom commands and
command referencing itself will lead to stack overflow. Both of these
issues are meant to be addressed._
5. TODO: Help messages, `which` command, `$nu.scope.aliases`, etc.
* Should we treat the aliases as commands or should they be separated
from regular commands?
6. Needs better error message and syntax highlight for recursed alias
(`alias f = f`)
7. Can't create alias with the same name as existing command (`alias ls
= ls -a`)
	* Might be possible to add support for it (not 100% sure)
8. Standalone `alias` doesn't list aliases anymore
9. Can't alias parser keywords (e.g., stuff like `alias ou = overlay
use` won't work)
	* TODO: Needs a better error message when attempting to do so

- a `match` statement at the end of the example loop to
- print a white dimmed `...` when the example is not set, i.e. set to
`None` in the `examples` method of the `Command` implementation of a
command
- pretty print the output of the associated example `Value` when it has
been defined

special-case ExternalStream in bytes starts-with (#8203)
# Description
`bytes starts-with` converts the input into a `Value` before running
.starts_with to find if the binary matches. This has two side effects:
it makes the code simpler, only dealing in whole values, and simplifying
a lot of input pipeline handling and value transforming it would
otherwise have to do. _Especially_ in the presence of a cell path to
drill into. It also makes buffers the entire input into memory, which
can take up a lot of memory when dealing with large files, especially if
you only want to check the first few bytes (like for a magic number).

This PR adds a special branch on PipelineData::ExternalStream with a
streaming version of starts_with.

# User-Facing Changes
Opening large files and running bytes starts-with on them will not take
a long time.

# 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

# Drawbacks
Streaming checking is more complicated, and there may be bugs. I tested
it with multiple chunks with string data and binary data and it seems to
work alright up to 8k and over bytes, though.

The existing `operate` method still exists because the way it handles
cell paths and values is complicated. This causes some "code
duplication", or at least some intent duplication, between the value
code and the streaming code. This might be worthwhile considering the
performance gains (approaching infinity on larger inputs).

Another thing to consider is that my ExternalStream branch considers
string data as valid input. The operate branch only parses Binary
values, so it would fail. `open` is kind of unpredictable on whether it
returns string data or binary data, even when passing `--raw`. I think
this can be a problem but not really one I'm trying to tackle in this
PR, so, it's worth considering.

pipe binary data to external commands (#8058)
Fixes #7615 

# Description

When calling external commands, we create a table from the pipeline data
to handle external commands expecting paginated input. When a binary
value is made into a table, we convert the vector of bytes representing
the binary bytes into a pretty formatted string. This results in the
pretty formatted string being sent to external commands instead of the
actual binary bytes. By checking whether the stdout of the call is being
redirected, we can decide whether to send the raw binary bytes or the
pretty formatted output when creating a table command.

# User-Facing Changes

When passing binary values to external commands, the external command
will receive the actual bytes instead of the pretty printed string. Use
cases that don't involve piping a binary value into an external command
are unchanged.

Fix hidden env vars not being hidden in closures (#8055)
# Description

This one fixes env not being hidden inside closure, reported in the
conversation under https://github.com/nushell/nushell/issues/6593

https://github.com/nushell/nushell/issues/6593
https://github.com/nushell/nushell/issues/7937 still persist. These
seems a bit more involved and might need hidden env tracking also in the
engine state... I'm not yet sure what's causing it.

Also re-enables some env-related tests and removes unused Value clone.

A fill command to replace str lpad and str rpad (#7846)
# Description

The point of this command is to allow you to be able to format ints,
floats, filesizes, and strings with an alignment, padding, and a fill
character, as strings. It's meant to take the place of `str lpad` and
`str rpad`.

```
> help fill
Fill and Align

Search terms: display, render, format, pad, align

Usage:
  > fill {flags}

Flags:
  -h, --help - Display the help message for this command
  -w, --width <Int> - The width of the output. Defaults to 1
  -a, --alignment <String> - The alignment of the output. Defaults to Left (Left(l), Right(r), Center(c/m), MiddleRight(cr/mr))
  -c, --character <String> - The character to fill with. Defaults to ' ' (space)

Signatures:
  <number> | fill -> <string>
  <string> | fill -> <string>

Examples:
  Fill a string on the left side to a width of 15 with the character '─'
  > 'nushell' | fill -a l -c '─' -w 15

  Fill a string on the right side to a width of 15 with the character '─'
  > 'nushell' | fill -a r -c '─' -w 15

  Fill a string on both sides to a width of 15 with the character '─'
  > 'nushell' | fill -a m -c '─' -w 15

  Fill a number on the left side to a width of 5 with the character '0'
  > 1 | fill --alignment right --character 0 --width 5

  Fill a filesize on the left side to a width of 5 with the character '0'
  > 1kib | fill --alignment middle --character 0 --width 10
```

Support extended unicode escapes in strings: "\u{10fff}" (#7883)
# Description

Support extended unicode escapes in strings with same syntax as Rust:
`"\u{6e}"`.

# User-Facing Changes

New syntax in string literals, `\u{NNNNNN}`, to go along with the
existing `\uNNNN`.
New syntax accepts 1-6 hex digits and rejects values greater than
0x10FFFF (max Unicode char)..

_(List of all changes that impact the user experience here. This helps
us keep track of breaking changes.)_

Won't break existing scripts, since this is new syntax.  

We might consider deprecating `char -u`, since users can now embed
unicode chars > 0xFFFF with the new escape.

add some startup performance metrics (#7851)
# Description

This PR changes the old performance logging with `Instant` timers. I'm
not sure if this is the best way to do it but it does help reveal where
time is being spent on startup. This is what it looks like when you
launch nushell with `cargo run -- --log-level info`. I'm using the
`info` log level exclusively for performance monitoring at this point.

Since you're in the repl, you can continue running commands. Here's the
output of `ls`, for instance.

Progress bar Implementation (#7661)
# Description

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

I implemented the status bar we talk about yesterday. The idea was
inspired by the progress bar of `wget`.
I decided to go for the second suggestion by `@Reilly`
> 2. add an Option<usize> or whatever to RawStream (and ListStream?) for
situations where you do know the length ahead of time

For now only works with the command `save` but after the approve of this
PR we can see how we can implement it on commands like `cp` and `mv`

When using `fetch` nushell will check if there is any `content-length`
attribute in the request header. If so, then `fetch` will send it
through the new `Option` variable in the `RawStream` to the `save`.
If we know the total size we show the progress bar 

![nu_pb01](https://user-images.githubusercontent.com/38369407/210298647-07ee55ea-e751-41b1-a84d-f72ec1f6e9e5.jpg)
but if we don't then we just show the stats like: data already saved,
bytes per second, and time lapse.

![nu_pb02](https://user-images.githubusercontent.com/38369407/210298698-1ef65f51-40cc-4481-83de-309cbd1049cb.jpg)

Please let me know If I need to make any changes and I will be happy to
do it.

# User-Facing Changes

A new flag (`--progress` `-p`) was added to the `save` command 
Examples:
```nu
fetch https://github.com/torvalds/linux/archive/refs/heads/master.zip | save --progress -f main.zip
fetch https://releases.ubuntu.com/22.04.1/ubuntu-22.04.1-desktop-amd64.iso | save --progress -f main.zip

Revert "Primitives now use color closures..." (#7710)
This temporarily reverts commit c5639cd9fa
(PR https://github.com/nushell/nushell/pull/7650). See
[here](https://github.com/nushell/nushell/pull/7650#issuecomment-1375036213)
for details; the PR is accidentally adding ANSI escape codes to strings
piped to externals.

I think we should revert the PR because we're only 1-2 days away from a
release; reverting it will give us more time to land+test a proper fix
in the next release cycle.

move BufferedReader out of nu-command (#7697)
src/main.rs has a dependency on BufferedReader
which is currently located in nu_command.

I am moving BufferedReader to a more relevant
location (crate) which will allow / eliminate main's dependency
on nu_command in a benchmark / testing environment...

now that @rgwood  has landed benches I want
to start experimenting with benchmarks related
to the parser.

For benchmark purposes when dealing with parsing
you need a very simple set of commands that show
how well the parser is doing, in other words
just the core commands... Not all of nu_command...

Having a smaller nu binary when running the benchmark CI
would enable building nushell quickly, yet still show us
how well the parser is performing...

Once this PR lands the only dependency main will have
on nu_command is create_default_context ---
meaning for benchmark purposes we can swap in a tiny
crate of commands instead of the gigantic nu_command
which has its "own" create_default_context...

It will also enable other crates going forward to
use BufferedReader.  Right now it is not accessible
to other lower level crates because it is located in a
"top of the stack crate".

Limit recursion to avoid stack overflow (#7657)
Add recursion limit to `def` and `block`.
Summary of this PR , it will detect if `def` call itself or not .
Then execute by using `stack` which I think best choice to use with this
design and core as it is available in all crates and mutable and
calculate the recursion limit on calling `def`.
Set 50 as recursion limit on `Config`.
Add some tests too .

Reorder flags in nu --help (#7672)
The ordering of flags in `nu --help` was a bit of a mess; I think it
grew organically over time. Related commands (like
`--config`/`--env-config`/`--plugin-config`) weren't grouped together,
common flags weren't near the top, and we weren't following alphabetical
ordering.

### Before

```bash
Flags:
  -h, --help - Display the help message for this command
  --stdin - redirect standard input to a command (with `-c`) or a script file
  -l, --login - start as a login shell
  -i, --interactive - start as an interactive shell
  -v, --version - print the version
  --testbin <String> - run internal test binary
  -c, --commands <String> - run the given commands and then exit
  --config <String> - start with an alternate config file
  --env-config <String> - start with an alternate environment config file
  --log-level <String> - log level for diagnostic logs (error, warn, info, debug, trace). Off by default
  --log-target <String> - set the target for the log to output. stdout, stderr(default), mixed or file
  -e, --execute <String> - run the given commands and then enter an interactive shell
  -t, --threads <Int> - threads to use for parallel commands
  -m, --table-mode <String> - the table mode to use. rounded is default.
  --plugin-config <String> - start with an alternate plugin signature file
```

### After

```bash
Flags:
  -h, --help - Display the help message for this command
  -c, --commands <String> - run the given commands and then exit
  -e, --execute <String> - run the given commands and then enter an interactive shell
  -i, --interactive - start as an interactive shell
  -l, --login - start as a login shell
  -m, --table-mode <String> - the table mode to use. rounded is default.
  -t, --threads <Int> - threads to use for parallel commands
  -v, --version - print the version
  --config <String> - start with an alternate config file
  --env-config <String> - start with an alternate environment config file
  --plugin-config <String> - start with an alternate plugin signature file
  --log-level <String> - log level for diagnostic logs (error, warn, info, debug, trace). Off by default
  --log-target <String> - set the target for the log to output. stdout, stderr(default), mixed or file
  --stdin - redirect standard input to a command (with `-c`) or a script file
  --testbin <String> - run internal test binary
```

The new ordering:

1. Groups commands with short flags together, sorted alphabetically by
short flag
1. Groups commands with only long flags together, sorted alphabetically
(with the exception of `--plugin-config` so we can keep related flags
together)

Conveniently, this puts the very commonly used `-c` at the top and the
very rarely used `--testbin` at the bottom.

Make get hole errors and cell path hole errors identical (improvement on #7002) (#7647)
# Description

This closes #7498, as well as fixes an issue reported in
https://github.com/nushell/nushell/pull/7002#issuecomment-1368340773

BEFORE:
```
〉[{foo: 'bar'} {}] | get foo
Error: nu:🐚:column_not_found (link)

  × Cannot find column
   ╭─[entry #5:1:1]
 1 │ [{foo: 'bar'} {}] | get foo
   · ────────┬────────   ─┬─
   ·         │            ╰── value originates here
   ·         ╰── cannot find column 'Empty cell'
   ╰────

〉[{foo: 'bar'} {}].foo
╭───┬─────╮
│ 0 │ bar │
│ 1 │     │
╰───┴─────╯
```
AFTER:
```
〉[{foo: 'bar'} {}] | get foo
Error: nu:🐚:column_not_found (link)

  × Cannot find column
   ╭─[entry #1:1:1]
 1 │ [{foo: 'bar'} {}] | get foo
   ·               ─┬        ─┬─
   ·                │         ╰── cannot find column 'foo'
   ·                ╰── value originates here
   ╰────

〉[{foo: 'bar'} {}].foo
Error: nu:🐚:column_not_found (link)

  × Cannot find column
   ╭─[entry #3:1:1]

   ·               ─┬  ─┬─

   ·                ╰── value originates here       
   ╰────
```

EDIT: This also changes the semantics of `get`/`select` `-i` somewhat.
I've decided to leave it like this because it works more intuitively
with `default` and `compact`.
BEFORE:
```
〉[{a:1} {b:2} {a:3}] | select -i foo | to nuon
null
```
AFTER:
```
〉[{a:1} {b:2} {a:3}] | select -i foo | to nuon
[[foo]; [null], [null], [null]]
```

# User-Facing Changes

Further cleanup of Span::test_data usage + span fixes (#7595)
# Description

Inspired by #7592

For brevity use `Value::test_{string,int,float,bool}`

Includes fixes to commands that were abusing `Span::test_data` in their
implementation. Now the call span is used where possible or the explicit
`Span::unknonw` is used.

## Command fixes
- Fix abuse of `Span::test_data()` in `query_xml`
- Fix abuse of `Span::test_data()` in `term size`
- Fix abuse of `Span::test_data()` in `seq date`
- Fix two abuses of `Span::test_data` in `nu-cli`
- Change `Span::test_data` to `Span::unknown` in `keybindings listen`
- Add proper call span to `registry query`
- Fix span use in `nu_plugin_query`
- Fix span assignment in `select`
- Use `Span::unknown` instead of `test_data` in more places

## Other
- Use `Value::test_int`/`test_float()` consistently
- More `test_string` and `test_bool`
- Fix unused imports


# User-Facing Changes

errors

Change other instances of $nothing to null (#7569)
# Description

Purely for consistency, various remaining instances of `$nothing`

Now, the only place that refers to `$nothing` is the parser code which

I'm currently [working on improving cell
paths](https://github.com/nushell/nushell/issues/7498#issuecomment-1356834798),
and I realized that I would need to make several improvements to `into
cellpath` along the lines of Jakub's comment here:
https://github.com/nushell/nushell/pull/7417#issuecomment-1345264955

like to remove it before the upcoming release.

Replace row conditions with closures in commands (#7428)
# Description

This PR changes some commands that previously accepted row conditions
(like `$it > 5`) as parameter to accept closures instead. The reasons
are:
a) The commands would need to move into parser keywords in the future
while they feel more like commands to be implemented in Nushell code as
a part of standard library.
b) In scripts, it is useful to store the predicate condition in a
variable which you can't do with row conditions.
c) These commands are not used that often to benefit enough from the
shorter row condition syntax

# User-Facing Changes

The following commands now accept **closure** instead of a **row
condition**:
- `take until`
- `take while`
- `skip until`
- `skip while`
- `any`
- `all`

This is a part of an effort to move away from shape-directed parsing.

Reduced LOC by replacing several instances of Value::Int {}, Value::Float{}, Value::Bool {}, and Value::String {} with Value::int(), Value::float(), Value::boolean() and Value::string() (#7412)
# Description

While perusing Value.rs, I noticed the `Value::int()`, `Value::float()`,
`Value::boolean()` and `Value::string()` constructors, which seem
designed to make it easier to construct various Values, but which aren't
used often at all in the codebase. So, using a few find-replaces
regexes, I increased their usage. This reduces overall LOC because
structures like this:
```
Value::Int {
  val: a,
  span: head
}
```
are changed into
```
Value::int(a, head)
```
and are respected as such by the project's formatter.
There are little readability concerns because the second argument to all
of these is `span`, and it's almost always extremely obvious which is
the span at every callsite.

Add OneOf shape to fix else (#7385)
# Description

fixes #7384 

This is a stop-gap fix until we remove type-directed parsing. With this,
you can create a `OneOf` shape that can be one of a list of syntax
shapes. This gives you a little more control than you get with `Any`,
allowing you to add `Block` without breaking other parsing rules.

`else` block will no longer capture variables as it will now use a block
instead of a closure.

Add logical xor operator (#7242)
We already have the binary `bit-xor` and the shortcircuiting logical
`or`(`||`) and `and`(`&&`).
This introduces `xor` as a compact form for both brevity and clarity.
You can express the operation through `not`/`and`/`or` with a slight
risk of introducing bugs through typos.

Operator precedence

`and` > `xor` > `or`

Added logic and precedence tests.

Make external command substitution works friendly(like fish shell, trailing ending newlines) (#7156)
# Description

As title, when execute external sub command, auto-trimming end
new-lines, like how fish shell does.

And if the command is executed directly like: `cat tmp`, the result
won't change.

Fixes: #6816
Fixes: #3980


Note that although nushell works correctly by directly replace output of
external command to variable(or other places like string interpolation),
it's not friendly to user, and users almost want to use `str trim` to
trim trailing newline, I think that's why fish shell do this
automatically.

If the pr is ok, as a result, no more `str trim -r` is required when
user is writing scripts which using external commands.

Remove unnecessary #[allow(...)] annotations (#6870)
* Remove unnecessary `#[allow]` annots

Reduce the number of lint exceptions that are not necessary with the
current state of the code (or more recent toolchain)

* Remove dead code from `FileStructure` in nu-command

* Replace `allow(unused)` with relevant feature switch

* Deal with `needless_collect` with annotations

* Change hack for needless_collect in `from json`

This change obviates the need for `allow(needless_collect)`
Removes a pessimistic allocation for empty strings, but increases
allocation size to `Value`

Probably not really worth it.

* Revert "Deal with `needless_collect` with annotations"

This reverts commit 05aca98445.

The previous state seems to better from a performance perspective as a
`Vec<String>` is lighter weight than `Vec<Value>`

Rename all?, any? and empty? (#6464)
Rename `all?`, `any?` and `empty?` to `all`, `any` and `is-empty` for sake of simplicity and consistency.

- More understandable for newcomers, that these commands are no special to others.
- `?` syntax did not really aprove readability. For me it made it worse.
- We can reserve `?` syntax for any other nushell feature.

Add plugin CLI argument (#6064)
* Add plugin CLI argument

While working on supporting CustomValues in Plugins I stumbled upon the
test utilities defined in [nu-test-support][nu-test-support]
and thought these will come in handy, but they end up being outdated.
They haven't been used or since engine-q's was merged, so they are
currently using the old way engine-q handled plugins, where it would
just look into a specific folder for plugins and call them without
signatures or registration. While fixing that I realized that there is
currently no way to tell nushell to load and save signatures into a
specific path, and so those integration tests could end up potentially
conflicting with each other and with the local plugins the person
running them is using.

So this adds a new CLI argument to specify where to store and load
plugin signatures from

I am not super sure of the way I implemented this, mainly
I was a bit confused about the distinction between
[src/config_files.rs][src/config_files.rs] and
[crates/nu-cli/src/config_files.rs][crates/nu-cli/src/config_files.rs].
Should I be moving the plugin loading function from the `nu-cli` one to
the root one?

[nu-test-support]: 9d0be7d96f/crates/nu-test-support/src/macros.rs (L106)
[src/config_files.rs]: 9d0be7d96f/src/config_files.rs
[crates/nu-cli/src/config_files.rs]: 9d0be7d96f/crates/nu-cli/src/config_files.rs

* Gate new CLI option behind plugin feature

* Rename option to plugin-config
