Bump rayon from 1.6.1 to 1.7.0 (#8328)
Bumps [rayon](https://github.com/rayon-rs/rayon) from 1.6.1 to 1.7.0.
<details>
<summary>Changelog</summary>
<p><em>Sourced from <a
href="https://github.com/rayon-rs/rayon/blob/master/RELEASES.md">rayon's
changelog</a>.</em></p>
<blockquote>
<h1>Release rayon 1.7.0 / rayon-core 1.11.0 (2023-03-03)</h1>
<ul>
<li>The minimum supported <code>rustc</code> is now 1.59.</li>
<li>Added a fallback when threading is unsupported.</li>
<li>The new <code>ParallelIterator::take_any</code> and
<code>skip_any</code> methods work like
unordered <code>IndexedParallelIterator::take</code> and
<code>skip</code>, counting items in
whatever order they are visited in parallel.</li>
<li>The new <code>ParallelIterator::take_any_while</code> and
<code>skip_any_while</code> methods work
like unordered <code>Iterator::take_while</code> and
<code>skip_while</code>, which previously had
no parallel equivalent. The &quot;while&quot; condition may be satisfied
from anywhere
in the parallel iterator, affecting all future items regardless of
position.</li>
<li>The new <code>yield_now</code> and <code>yield_local</code>
functions will cooperatively yield
execution to Rayon, either trying to execute pending work from the
entire
pool or from just the local deques of the current thread,
respectively.</li>
</ul>
<h1>Release rayon-core 1.10.2 (2023-01-22)</h1>
<ul>
<li>Fixed miri-reported UB for SharedReadOnly tags protected by a
call.</li>

Bump tempfile from 3.3.0 to 3.4.0 (#8329)
Bumps [tempfile](https://github.com/Stebalien/tempfile) from 3.3.0 to
3.4.0.
<details>
<summary>Changelog</summary>
<p><em>Sourced from <a
href="https://github.com/Stebalien/tempfile/blob/master/NEWS">tempfile's
changelog</a>.</em></p>
<blockquote>
<h1>3.4.0</h1>
<p>SECURITY: Prior <code>tempfile</code> releases depended on
<code>remove_dir_all</code> version 0.5.0 which was vulnerable to a <a
href="https://github.com/XAMPPRocky/remove_dir_all/security/advisories/GHSA-mc8h-8q98-g5hr">TOCTOU
race</a>. This same race is present in rust versions prior to
1.58.1.</p>
<p>Features:</p>
<ul>
<li>Generalized temporary files: <code>NamedTempFile</code> can now
abstract over different kinds of files (e.g.,
unix domain sockets, pipes, etc.):
<ul>
<li>Add <code>Builder::make</code> and <code>Builder::make_in</code> for
generalized temp file
creation.</li>
<li>Add <code>NamedTempFile::from_parts</code> to complement
<code>NamedTempFile::into_parts</code>.</li>
<li>Add generic parameter to <code>NamedTempFile</code> to support
wrapping non-File types.</li>
</ul>
</li>
</ul>
<p>Bug Fixes/Improvements:</p>
<ul>
<li>Don't try to create a temporary file multiple times if the file path
has been fully specified by
the user (no random characters).</li>
<li><code>NamedTempFile::persist_noclobber</code> is now always atomic
on linux when <code>renameat_with</code> is
supported. Previously, it would first link the new path, then unlink the
previous path.</li>
<li>Fix compiler warnings on windows.</li>
</ul>
<p>Trivia:</p>
<ul>
<li>Switch from <code>libc</code> to <code>rustix</code> on wasi/unix.
This now makes direct syscalls instead of calling
through libc.</li>
<li>Remove <code>remove_dir_all</code> dependency. The rust standard
library has optimized their internal version
significantly.</li>
<li>Switch to official windows-sys windows bindings.</li>
</ul>
<p>Breaking:</p>
<ul>
<li>The minimum rust version is now <code>1.48.0</code>.</li>
<li>Mark most functions as <code>must_use</code>.</li>
<li>Uses direct syscalls on linux by default, instead of libc.</li>
<li>The new type parameter in <code>NamedTempFile</code> may lead to
type inference issues in some cases.</li>
</ul>

Put a lock around cargo build invocations for plugin tests (#8333)
I think this _might_ fix the issues we've been seeing with plugin tests.

In a nutshell, the plugin tests run `cargo build` to ensure that plugins
have been built:
f6ca62384e/crates/nu-test-support/src/commands.rs (L6)

This PR adds a mutex to ensure that we're never running `cargo build`
concurrently. It also uses an atomic bool to signal when plugins have
already been built, so we can avoid invoking `cargo build` multiple
times unnecessarily.

I can't be certain yet, but I'm guessing the macOS CI problems we've
been seeing come from plugin tests clobbering each other (something
like: test 1 builds the `foo` plugin, then test2 invokes `cargo build`
again and deletes the `foo` plugin from disk).

changes Reqwest to Ureq. (#8320)
# Description

_(Thank you for improving Nushell. Please, check our [contributing
guide](../CONTRIBUTING.md) and talk to the core team before making major
changes.)_

This pull request removes `Reqwest` and replaces it with `Ureq` to
remove some of our dependencies, giving us faster compile times as well
as smaller binaries. `Ureq` does not have an async runtime included so
we do not need build heavy dependencies such as `Tokio`. From older
tests I had the number of build units be reduced from `430 -> 392`.
The default of `Ureq` uses `Rustls` but it has been configured to
instead use `native_tls` which should work exactly the same as the `tls`
works now.
I removed `content-length` from the http commands as after refactoring i
did not see a reason to have it available, correct me if this is
something we should preserve.

In the medium, to long term, we should maybe consider changing to
`rustls` to have the same `tls` on all platforms.

# User-Facing Changes

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

# 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

# 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.

FEATURE: add the example results to the scope (#8319)
Related to #8189.
Should close #8302.

Important to:
- have a complete `$nu` structure with all available information
- generate an accurate website, because the `make_docs.nu` script of
`nushell.github.io` uses `$nu.scope.command` to generate the pages of
https://nushell.sh/commands/

> **Note**
> i was looking for "scope" in the source of `nushell` to augment
`$nu.scope` and i found `crates/nu-engine/src/scope.rs` that defines
`nu_engine::scope::create_scope` which lead me to
`nu_engine::scope::ScopeData.collect_commands`.
> i hope this is the right file 😌 

# Description
this PR slightly modifies
`nu_engine::scope::ScopeData.collect_commands`:
- add the "result" column to `$nu.scope.commands.examples`
- put the result of the example when a valid `Option(Value)`
- put a `Value::Nothing` when the result is set to `None` in the source
of the command

# User-Facing Changes
users can now access the results of all examples in
```bash
$nu.scope.commands | where name == <command> | get examples.0.result
```

## example...
### ...with a command that defines examples: `merge`
```bash
>_ $nu.scope.commands | where name == merge | get examples.0 | reject description | table --expand

Fix CPU usage info in sys (#8321)
Closes #8264. This PR does a few things to fix the `usage` column in
`sys.cpu`:

1. Sleep a while (~400ms) between calls to `sys.refresh_cpu()`, [as
required by
`sysinfo`](https://docs.rs/sysinfo/latest/sysinfo/trait.SystemExt.html#method.refresh_cpu)
2. Change `sys` to return a `LazyRecord` (so you can do things like `sys
| get host` instantly without waiting for CPU info)
3. Update our `sysinfo` dependency to [fix CPU usage calculations on
Linux](https://github.com/GuillaumeGomez/sysinfo/pull/946)

CPU usage is no longer always reported as zero:

Make the default prompt play nice with basic fonts (#8080)
# Description
This commit changes the `PROMPT_INDICATOR` and
`PROMPT_INDICATOR_VI_NORMAL` in the default_env and sample_login files.
It also changes its missing fallback in the prompt.rs file.

This has the intention of making the default prompt friendlier when
dealing with basic terminals that may not support displaying a huge
range of the Unicode standard, or users who don't want to get out of
their way to install custom fonts for their terminals. It's also
nicer/more balanced on the eyes, to me, and brings it in line with the
logo of nushell `nu>`.

# User-Facing Changes
New installations of nushell will have > as the default prompt
indicator, and running `config reset` will also change it. This might be
confusing for a few seconds, it could be minor enough that it just feels
slightly off. Anyone who has, for some reason, unset the
PROMPT_INDICATOR variable, or set it to $nothing, will also receive the
`>` treatment.

Users running on basic terminals (like cmd.exe on Windows 10) should no
longer face font issues with the default basic prompt.

# Drawbacks
The Unicode arrow is pretty cool. And it predates many of us. Maybe it's
worth keeping. One argument I could see, and mildly disagree with, is
that it might make users lean towards installing a modern font for their
terminal which will would have good consequences in the future.

REFACTOR: move the standard library to a less-confusing place (#8265)
# Description
we've discussed a bit about the location of the standard library in the
#standard-library channel of the discord server => **the previous
location, `crates/nu-utils/src/sample_config/`, was a bit confusing**
- is `std.nu` a config file, just as `default_config.nu` or
`default_env.nu`?
- what is this `tests.nu` file inside the `sample_config/`?

in this PR, i propose moving the standard library to
`crates/nu-utils/standard_library/` for a few reasons:
- `std.nu` is not a config file, so it should not be next to config
files in a `sample_config/` directory
- `tests.nu` is confusing if mixed with other unrelated files
- `crates/nu-utils/` appears to be a good place for the standard library
as it is meant to be a tool for `nushell`
- i thought it would be strange to have `std.nu` inside
`crates/nu-utils/src/` as this directory is generally filled with `rust`
files, right?

these are the reasons why i choose to propose
`crates/nu-utils/standard_library/` 😋

# User-Facing Changes
the standard library is now used with
```bash
use crates/nu-utils/standard_library/std.nu
```
and the tests are run with
```bash
nu crates/nu-utils/standard_library/tests.nu
```

Document and critically review ShellError variants - Ep. 1 (#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.

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

- Name fields on `ShellError::OperatorOverflow`
- Name fields on `ShellError::PipelineMismatch`
- Add doc to `ShellError::OnlySupportsThisInputType`
- Name `ShellError::OnlySupportsThisInputType`
- Name field on `ShellError::PipelineEmpty`
- Comment about issues with `TypeMismatch*`
- Fix a few `exp_input_type`s
- Name fields on `ShellError::InvalidRange`

# User-Facing Changes

Fix CPU frequency in sys output (#8275)
The `sys | get cpu.freq` column (supposed to contain the frequency for
each CPU core in megahertz) was incorrect for 2 reasons:
1. We weren't telling the `sysinfo` crate to refresh CPU frequency info
2. We were overwriting the values in the column with the systemwide

Type mismatch span fix #7288 (#8271)
# Description

This change fixes the bug associated with an incorrect span in
`type_mismatch` error message as described in #7288

The `span` argument in the method `into_value` was not being used to
convert a `PipelineData::Value` type so when called in
[eval_expression](https://github.com/nushell/nushell/blob/main/crates/nu-engine/src/eval.rs#L514-L515),
the original expression's span was not being used to overwrite the
result of `eval_subexpression`.

# User-Facing Changes

Using the example described in the issue, the whole bracketed
subexpression is correctly underlined.

Behavior before change:

```
let val = 10
($val | into string) + $val
Error: nu:🐚:type_mismatch

  × Type mismatch during operation.
   ╭─[entry #2:1:1]

   ·              ╰── string

```

Behavior after change:
```

  × Type mismatch during operation.

Fix insecure + max-time arguments for HTTP commands. (#8266)
# Description

Follow up of https://github.com/nushell/nushell/pull/8255

Sorry about the max-time argument, I didn't pay attention to the
copy-paste. Regarding the insecure argument, the problem was before I
began to work on the refacto. My mistake was to not have tested this
argument.

FEATURE: add the first draft of the standard library (#8150)
hello there 👋 😋 

as discussed over on the discord server, in `#standard-library`, there
is this new project of putting together a bunch of "_standard_" scripts
and functions and propose a `nushell` "_standard library_".
this PR is the first one in that direction 🎉 

> **Note**
> ~~this PR is still a draft to have some feedback 😌~~ 
> this PR is now **READY FOR REVIEW** 🎉 

# Description
this PR implements the following few commands:
- the `assert` familly with a private helper `_assert`
- a version of the `match` statement

i've also added some examples in the docstrings of the functions 👍 

# User-Facing Changes
the standard library can now be used with
```bash
use crates/nu-utils/src/sample_config/std.nu
```
from the root of the `nushell` source

# Tests + Formatting
i've written a first draft of a
[`tests.nu`](https://github.com/amtoine/nushell/blob/feature/first-draft-of-the-standard-library/crates/nu-utils/src/sample_config/tests.nu)
module which
- tests the `assert` familly of function in `test_assert`
- tests the rest of the standard library in `tests`

the tests are run with
```bash
nu crates/nu-utils/src/sample_config/tests.nu
```
through the `main` function and should give no error 👍 

> **Note**
> if you change one of the test line, there should be an error popping
when running the tests 😉

cratification: Example support (#8231)
# Description

When the crate nu_cmd_lang crate was created last week example_test.rs
was copied over from nu_command
to nu_cmd_lang. By doing this there was a set of methods in
example_test.rs that existed in both crates...

This PR removes the redundancy by moving all of those duplicated methods
into the crate nu_test_support in a newly created file called
example_support.rs

It's supposed to be an empty table, but it has two rows. I removed the
duplicates.

`into datetime --list` will print out a correct table.

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/5780,
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

# 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

# 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.

Simplify str trim command (#8205)
### What?

This change removes 3 flags (`--all`, `--both`, and `--format`) from
`str trim`. This is a net reduction of ~450 LoC and `str trim` no longer
depends on `fancy_regex`.

### Why?

I found these flags to be quite confusing when reviewing `str trim`
earlier today:

1. `--all` removes characters even if they're in the centre of the the
string.
- This is arguably not "trimming"! In all programming languages I'm
familiar with, trimming only affects the start and end of a string.
    - If someone needs to do this, `str replace` is more natural IMO
2. `--both` trims from the left and right
- Confusing and unnecessary given that this is also the default
behaviour
3. `--format` replaces multiple spaces with a single space, even in the
centre of the string
- Again, I don't think this falls under the scope of "trimming". IMO
`str replace` is a more natural fit

I believe that `str trim` is simpler and easier to understand after this
change.

### Before

```
〉help str trim
Trim whitespace or specific character

Search terms: whitespace, strip, lstrip, rstrip

Usage:
  > str trim {flags} ...(rest)

Flags:
  -h, --help - Display the help message for this command
  -c, --char <String> - character to trim (default: whitespace)
  -l, --left - trims characters only from the beginning of the string
  -r, --right - trims characters only from the end of the string
  -a, --all - trims all characters from both sides of the string *and* in the middle
  -b, --both - trims all characters from left and right side of the string
  -f, --format - trims spaces replacing multiple characters with singles in the middle
```

### After

```
〉help str trim
Trim whitespace or specific character

Search terms: whitespace, strip, lstrip, rstrip

Usage:
  > str trim {flags} ...(rest)

Flags:
  -h, --help - Display the help message for this command
  -c, --char <String> - character to trim (default: whitespace)
  -l, --left - trims characters only from the beginning of the string
  -r, --right - trims characters only from the end of the string

FEATURE: print example command results in the help (#8189)
Should close #8035.

> **Note**
> this is my first technical PR for `nushell`
> - i might very well miss things
> - i tried to be as complete as possible about the changes
> - please require further changes if i did something wrong, i'm open to
any remark 😌

# Description
this PR adds, when it is defined in the `examples` method of the
`Command` implementations, the output of the examples to the output of
the `help` command.

this PR
- only modifies `crates/nu-engine/src/documentation.rs` and the
`get_documentation` function
- defines a new `WD` constant to print a **W**hite **D**immed `...`
- 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

> **Warning**
> LIMITATIONS:
> - i use snippets from `crates/nu-protocol/src/pipeline_data.rs`
> - the table creation from `pub PipelineData::print`, i.e. the `let
decl_id = ...;` and `let table = ...;` in the change
> - the table item printing from `PipelineData::write_all_and_flush`,
i.e. the `for item in table { ... }`
>
> ADDRESSED:
> - ~~the formatting of the output is not perfect and has to be fully
left aligned with the first column for now~~ (fixed with
[`5abeefd558c34ba9bae15e2f183ff4625442921e`..`a62be1b5a2c730959da5dbc028bb91ffe5093f63`](5abeefd558c34ba9bae15e2f183ff4625442921e..a62be1b5a2c730959da5dbc028bb91ffe5093f63))
> - ~~i'm using `.unwrap()` on both the changes above, not sure how to
handle this for now~~ (fixed for now thanks to 49f1dc080)
> - ~~the tests and `clippy` checks do not pass for now, see below~~
(`clippy` now is happy with 49f1dc080 and the tests pass with
11666bc715)

# User-Facing Changes
the output of the `help <command>` command is now augmented with the
outputs of the examples, when they are defined.
- `with-env`
```bash
> help with-env
...
Examples:
  Set the MYENV environment variable
  > with-env [MYENV "my env value"] { $env.MYENV }
  my env value

  Set by primitive value list
  > with-env [X Y W Z] { $env.X }
  Y

  Set by single row table
  > with-env [[X W]; [Y Z]] { $env.W }
  Z

  Set by key-value record
  > with-env {X: "Y", W: "Z"} { [$env.X $env.W] }
  ╭───┬───╮
  │ 0 │ Y │
  │ 1 │ Z │
  ╰───┴───╯
```
instead of the previous
```bash
> help with-env
...
Examples:
  Set the MYENV environment variable
  > with-env [MYENV "my env value"] { $env.MYENV }

  Set by primitive value list
  > with-env [X Y W Z] { $env.X }

  Set by single row table
  > with-env [[X W]; [Y Z]] { $env.W }

  Set by key-value record
  > with-env {X: "Y", W: "Z"} { [$env.X $env.W] }
```
- `merge`
```bash
> help merge
...
Examples:
  Add an 'index' column to the input table
  > [a b c] | wrap name | merge ( [1 2 3] | wrap index )
  ╭───┬──────╮
  │ # │ name │
  ├───┼──────┤
  │ 1 │ a    │
  │ 2 │ b    │
  │ 3 │ c    │
  ╰───┴──────╯

  Merge two records
  > {a: 1, b: 2} | merge {c: 3}
  ╭───┬───╮
  │ a │ 1 │
  │ b │ 2 │
  │ c │ 3 │
  ╰───┴───╯

  Merge two tables, overwriting overlapping columns
  > [{columnA: A0 columnB: B0}] | merge [{columnA: 'A0*'}]
  ╭───┬─────────┬─────────╮
  │ # │ columnA │ columnB │
  ├───┼─────────┼─────────┤
  │ 0 │ A0*     │ B0      │
  ╰───┴─────────┴─────────╯
```
instead of the previous
```bash
> help merge
...
Examples:
  Add an 'index' column to the input table
  > [a b c] | wrap name | merge ( [1 2 3] | wrap index )

  Merge two records
  > {a: 1, b: 2} | merge {c: 3}

  Merge two tables, overwriting overlapping columns
  > [{columnA: A0 columnB: B0}] | merge [{columnA: 'A0*'}]
