Support passing an empty list to sort, uniq, sort-by, and uniq-by (issue #5957) (#8669)
# Description

Currently, all four of these commands return a (rather-confusing)
spanless error when passed an empty list:

```
> [] | sort
Error: 
  × no values to work with
  help: no values to work with
```

This PR changes these commands to always output `[]` if the input is
`[]`.

```
> [] | sort
╭────────────╮
│ empty list │
╰────────────╯
> [] | uniq-by foo
╭────────────╮
│ empty list │
╰────────────╯
```

I'm not sure what the original logic was here, but in the case of `sort`
and `uniq`, I think the current behavior is straightforwardly wrong.

`sort-by` and `uniq-by` are a bit more complicated, since they currently
try to perform some validation that the specified column name is present
in the input (see #8667 for problems with this validation, where a
possible outcome is removing the validation entirely). When passed `[]`,
it's not possible to do any validation because there are no records.
This opens up the possibility for situations like the following:

```
> [[foo]; [5] [6]] | where foo < 3 | sort-by bar
╭────────────╮
│ empty list │
╰────────────╯
```

I think there's a strong argument that `[]` is the best output for these
commands as well, since it makes pipelines like `$table | filter
$condition | sort-by $column` more predictable. Currently, this pipeline
will throw an error if `filter` evaluates to `[]`, but work fine
otherwise. This makes it difficult to write reliable code, especially
since users are not likely to encounter the `filter -> []` case in
testing (issue #5957). The only workaround is to insert manual checks
for an empty result. IMO, this is significantly worse than the "you can
typo a column name without getting an error" problem shown above.

Other commands that take column arguments (`get`, `select`, `rename`,
etc) already have `[] -> []`, so there's existing precedent for this
behavior.

The core question here is "what columns does `[]` have"? The current
behavior of `sort-by` is "no columns", while the current behavior of
`select` is "all possible columns". Both answers lead to accepting some
likely-buggy code without throwing on error, but in order to do better
here we would need something like `Value::Table` that tracks columns on
empty tables.

If other people disagree with this logic, I'm happy to split out the
`sort-by` and `uniq-by` changes into another PR.

# User-Facing Changes

`sort`, `uniq`, `sort-by`, and `uniq-by` now return `[]` instead of
throwing an error when input is `[]`.

# After Submitting

> If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.

The existing behavior was not documented, and the new behavior is what
you would expect by default, so I don't think we need to update
documentation.

Fix record-to-JSON conversion for HTTP commands (#8663)
This PR fixes a bug introduced in
https://github.com/nushell/nushell/pull/8571.

We were accidentally converting a `Result<Value, ShellError>` to JSON
instead of converting a `Value`. The upshot was that we were sending
JSON like `{"Ok":{"foo":"bar"}}` instead of `{"foo":"bar"}`.

This was an easy bug to miss, because `ureq::send_json()` accepts any
`impl serde::Serialize`. I've added a test to prevent regression.

auto-expand paths in the $nu variable (#8653)
# Description

I recently ran into an issue where one of the $nu paths was not expanded
and was causing issue because $env.PWD did not equal $nu.temp-path, even
though I was in $nu.temp-path. The reason it didn't match was because my
temp path was symlinked. This PR fixes that issue by expanding the paths
with canonicalize_with().

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<>`.

Fix select on empty lists (#8651)
This PR fixes `select` when given an empty list; it used to return
`null` when given an empty list. I also cleaned up other `select` tests
while I was in the area.

### Before:

```
> [] | select a | to nuon
null
```

### After:

```
> [] | select a | to nuon
[]
```

It looks like the previous behaviour was accidentally introduced by
[this PR](https://github.com/nushell/nushell/pull/7639).

Require that values that look like numbers parse as numberlike (#8635)
# Description

Require that any value that looks like it might be a number (starts with
a digit, or a '-' + digit, or a '+' + digits, or a special form float
like `-inf`, `inf`, or `NaN`) must now be treated as a number-like
value. Number-like syntax can only parse into number-like values.
Number-like values include: durations, ints, floats, ranges, filesizes,
binary data, etc.

Variables that don't bind are set to `$nothing` so that they can be

stdlib: optimize test search and add better errors (#8626)
the first part of this PR comes from a request from @presidento in

this PR
- computes `module_search_pattern` to only `ls` the selected modules =>

# Description

This removes autoprinting the final value of a loop, much in the same
spirit as not autoprinting values at the end of statements. As we fix
these corner cases, it becomes more consistent that to print to the
screen in a script, you use the `print` command.

This gives a noticeable performance improvement as a bonus.

Before:
```
C:\Source\nushell〉 for x in 1..10 { $x }
1
2
3
4
5
6
7
8
9
10
```
Now:
```
C:\Source\nushell〉 for x in 1..10 { $x }
C:\Source\nushell〉
```

# User-Facing Changes

**BREAKING CHANGE**

Loops like `for`, `loop`, and `while` will no longer automatically print
loop values to the screen.

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 │
╰───┴─────╯
```

standard library: bring the tests into the main CI (#8525)
Should close one of the tasks in #8450.

# Description
> **Note**
> in order of appearance in the global diff

- 1b7497c419 adds the `std-tests` job to
the CI which
  1. installs `nushell` in the runner
  2. run the `tests.nu` module
> see `open .github/workflows/ci.yml | get jobs.std-tests | to yaml`

-
[`ec85b6fd`..`9c122115`](ec85b6fd3fc004cd94e3fada5c8e5fe2714fd629..9c12211564ca8ee90ed65ae45776dccb8f8e4ef1)
is where all the magic happens => see below
- 🧪 799c7eb7fd introduces some
bugs and failing test to see how the CI behaves => see how the [tests
failed](https://github.com/nushell/nushell/actions/runs/4460098237/jobs/7833018256)
as expected 
- 🧪 and c3de1fafb5 reverts the
failing tests, i.e. the previous commit, leaving a standard library
whose tests all pass 🎉 => see the [tests
passing](https://github.com/nushell/nushell/actions/runs/4460153434/jobs/7833110719?pr=8525#step:5:1)
now ✔️

## the changes to the runner
> see
[`ec85b6fd`..`9c122115`](ec85b6fd3fc004cd94e3fada5c8e5fe2714fd629..9c12211564ca8ee90ed65ae45776dccb8f8e4ef1)

the issue with the previous runner was the following: the clever trick
of using `nu -c "use ...; test"` did print the errors when occuring but
they did not capture the true "failure", i.e. in all cases the
`$env.LAST_EXIT_CODE` was set to `0`, never stopping the CI when a test
failed 🤔

i first tried to `try` / `catch` the error in
ec85b6fd3f which kinda worked but only
throw a single error, the first one

i thought it was not the best and started thinking about a solution to
have a complete report of all failing tests, at once, to avoid running
the CI multiple times!

the easiest solution i found was the one i implemented in
9c12211564
> **Warning**
> this changes the structure of the runner quite a bit, but the `for`
loops where annoying to manipulate structured data and allow the runner
to draw a complete report...

now the runner does the following
- compute the list of all available tests in a table with the `file`,
`module` and `name` columns (first part of the pipe until `flatten` and
`rename`)
- run the tests one by one computing the new `pass` column
  - with a `log info`
- captures the failing ones => puts `true` in `pass` if the test passes,
`false` otherwise
- if at least one test has failed, throw a single error with the list of
failing tests

### hope you'll like it 😌

Speed up tight loop benchmarks (#8609)
# Description

This does a few speedups for tight loops:
* Caches the DeclId for `table` so we don't look it up. This means users
can't easily replace the default one, we might want to talk about this
tradeoff. The lookup for finding `table` in a tight loop is currently
pretty heavy. Might be another way to speed this up.
* `table` no longer pre-calculates the width. Instead, it only
calculates the width when printing a table or record.
* Use more efficient way of collecting the block of each loop
* When printing output, only get the config when needed

Combined, this drops the runtime from a million loop tight iteration
from 1sec 8ms to 236ms.

Move variables to var stack (#8604)
# Description

This moves the representation of variables on the stack to a Vec, which
more closely resembles a stack. For small numbers of variables live at
any one point, this tends to be more efficient than a HashMap. Having a
stack-like vector also allows us to remember a stack position,
temporarily push variables on, then quickly drop the stack back to the
original size when we're done. We'll need this capability to allow
matching inside of conditions.

On this mac, a simple run of:

`timeit { mut x = 1; while $x < 1000000 { $x += 1 } }`

Went from 1 sec 86 ms, down to 1 sec 2 ms. Clearly, we have a lot more
ground we can make up in looping speed 😅 but it's nice that for fixing
this to make matching easier, we also get a win in terms of lookup speed
for small numbers of variables.

Make HTTP requests cancellable when trying to connect (#8591)

Prior to this change, the `http` commands could get stuck for 30s while
attempting to make a connection to a remote server. After this change,
`ctrl+c` works as expected:

To make this work, we perform blocking `ureq` calls in a background
thread and poll the channel while checking `ctrl+c`.

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

Make timeit work with command calls (#8594)
# Description

Allows `timeit` to also run commands directly, eg) `timeit ls -la`

# User-Facing Changes

Additional capabilities to `timeit`.

# Tests + Formatting

Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

Move timeit to use blocks. Make match vars immutable (#8592)
# Description

This does a couple random changes/fixes:

* Moves `timeit` to use a block instead of a closure. This makes it a
bit more flexible.
* Moves var bindings in patterns to be immutable

# User-Facing Changes

`timeit` now takes a block and no arguments.

Add pattern matching (#8590)
# Description

This adds `match` and basic pattern matching.

An example:

```
match $x {
  1..10 => { print "Value is between 1 and 10" }
  { foo: $bar } => { print $"Value has a 'foo' field with value ($bar)" }
  [$a, $b] => { print $"Value is a list with two items: ($a) and ($b)" }
  _ => { print "Value is none of the above" }
}
```

Like the recent changes to `if` to allow it to be used as an expression,
`match` can also be used as an expression. This allows you to assign the
result to a variable, eg) `let xyz = match ...`

I've also included a short-hand pattern for matching records, as I think
it might help when doing a lot of record patterns: `{$foo}` which is
equivalent to `{foo: $foo}`.

There are still missing components, so consider this the first step in
full pattern matching support. Currently missing:
* Patterns for strings
* Or-patterns (like the `|` in Rust)
* Patterns for tables (unclear how we want to match a table, so it'll
need some design)
* Patterns for binary values
* And much more

tweak logging format (#8588)
# Description

This PR just tweaks the std.nu logging a bit. It looks like this after
this PR. I like the ability to have a parse-able file, which is why
there are pipes, and I like to have a pretty granular time date stamp in
order to get rough performance metrics.

feat: added multiple options to http commands (#8571)
# Description

All `http` commands now have a `-f` flag which for now contains the
`headers`, `body` and `status` fields (we can later add stuff like
`is-redirect` or `cookies`).


![image](https://user-images.githubusercontent.com/3835355/227048504-6686445d-ad2e-4f5d-905d-e71b3a4b81a6.png)

*Try it yourself*
```
http get http://mockbin.org/bin/630069dc-2c09-483a-a484-672561b7de14
http get -f http://mockbin.org/bin/630069dc-2c09-483a-a484-672561b7de14
```

The `http` commands can also now use the `-e` flag, which stands for
`--allow-errors`. When the status code is `>= 400`, it will still allow
you to interpret it like a normal response.


![image](https://user-images.githubusercontent.com/3835355/227047790-b9f5a25f-2c0d-4741-881f-4189b23e4ef6.png)

*Try it yourself*
```
http get http://mockbin.org/bin/2ebd3d27-bdc2-4ee8-b042-0bc2c0d1ad2a # should fail like usual
http get -e http://mockbin.org/bin/2ebd3d27-bdc2-4ee8-b042-0bc2c0d1ad2a # will return the body
http get -e -f http://mockbin.org/bin/2ebd3d27-bdc2-4ee8-b042-0bc2c0d1ad2a # will let you see the full response
```

# User-Facing Changes

- Adds `-f` (`--full`) to all `http` commands
- Adds `-e` (--allow-errors) to all `http` commands

FIX: do not allow *start > end* in error make spans (#8570)
This should close #8567.

# Description
this PR throws an error when `start > end` in the most complete branch
of `ErrorMake::run`, i.e. when `$.msg`, `$.label.text`, `$.label.start`
and `$.label.end` are defined.

i've also added a `error_start_bigger_than_end_should_fail` test to
check that it does indeed return the right error.

# User-Facing Changes
no more crash when manipulating span bounds and a clear error, e.g.
```bash
>_ error make {msg: "msg" label: {text: "text" start: 1010 end: 1000}}
Error:
  × invalid error format.

fixes the ability to have multiple modifiers on keybindings (#8579)
# Description

This PR fixes a bug that prevented you from having multiple modifiers on
your keybindings.

TODO:
- The docs need to be fixed too
https://www.nushell.sh/book/line_editor.html#keybindings.
(https://github.com/nushell/nushell.github.io/pull/840)
- I think reedline needs to be changed to show this too since it
provides the list of available modifiers.
(https://github.com/nushell/reedline/pull/559)

Now you can do something like this where `shift` and `alt` are combined
with an underscore.
```
  {
    name: fuzzy_history_fzf
    modifier: shift_alt
    keycode: char_r
    mode: [emacs , vi_normal, vi_insert]
    event: {
blah
}
```
Here's the list of available combinations
```rust
        "control" => KeyModifiers::CONTROL,
        "shift" => KeyModifiers::SHIFT,
        "alt" => KeyModifiers::ALT,
        "none" => KeyModifiers::NONE,
        "shift_alt" | "alt_shift" => KeyModifiers::SHIFT | KeyModifiers::ALT,
        "control_shift" | "shift_control" => KeyModifiers::CONTROL | KeyModifiers::SHIFT,
        "control_alt" | "alt_control" => KeyModifiers::CONTROL | KeyModifiers::ALT,
        "control_alt_shift" | "control_shift_alt" => {
            KeyModifiers::CONTROL | KeyModifiers::ALT | KeyModifiers::SHIFT
        }

from ssv --aligned-columns should separate lines by character index instead of byte index (#8558)
# Description

## Symptom
Lines which are input into `from ssv --aligned-columns` are split
incorrectly of they contain utf-8 characters which have the length of
multiple bytes. Notice how the values of the `Bars` column bleeds into
the `Security` column in the following output (the big grey areas are
censored data ;) ):

![before-patch](https://user-images.githubusercontent.com/17351844/226757737-be7ca493-5c64-4a91-9153-984df515bb8c.png)

## Problem
The function behind `from ssv --aligned-columns` splits lines into
fields by byte index (which is default behavior of str.get(...) in Rust)
instead of character index. If the header row has a different length in
bytes than the remaining table rows, the split is executed incorrectly.

## Solution
The function behind `from ssv --aligned-columns1 now separates lines by
character index instead of byte index. This productes the following
(correct) output (the big grey areas are censored data ;) ):

![after-patch](https://user-images.githubusercontent.com/17351844/226757850-7acaebf3-2d40-4f85-b76e-64e465254bda.png)

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.
