fix: fixed typo and improved Value TypeMismatch exceptions (#8324)
# Description

This PR aims to improve `TypeMismatch` exception that occurs when
comparing two values with `<`, `>`, `<=` or `>=` operators.

*Before*

This PR also bundles a small refactor for histogram forbidden column
names exception, previous implementation forgot a column name in the
message, to avoid this, I'm re-using the same array for checking and
error display

# User-Facing Changes

Not much changes except a better and more readable exception for the
user

# Tests + Formatting

Does not break any tests, formatting passes as well :)

FEATURE: add --raw. --tabs and --indent to to nuon as in to json (#8366)
Should close #7255.

# Description
**TL;DR**: this PR adds `--indent <int>`, `--tabs <int>` and `--raw` to
control a bit more the `string` output of `to nuon`, as done in `to
json` already, the goal being to promote the `NUON` format through easy
to read and formatted output `.nuon` files 😋

### outside of `crates/nu-command/src/formats/to/nuon.rs`
as the signature of `value_to_string` has changed, the single call to it
outside of its module definition has been changed to use default values
=> `value_to_string(&value, Span::unknown(), 0, &None)` in
`crates/nu-command/src/filters/uniq.rs`

### changes to `ToNuon` in `crates/nu-command/src/formats/to/nuon.rs`
- the signature now features `--raw`, `--indent <int>` and `--tabs
<int>`
- the structure of the `run` method is inspired from the one in `to
json`
  - we get the values of the arguments
  - we convert the input to a usable `Value`
- depending on whether the user raised `--raw`, `--indent` or `--tabs`,
we call the conversion to `string` with different values of the
indentation, starting at depth 0
- finally, we return `Ok` or a `ShellError::CantConvert` depending on
the conversion result
- some tool functions
- `get_true_indentation` gives the full indentation => `indent` repeated
`depth` times
- `get_true_separators` gives the line and field separators => a `("\n",
"")` when using some formatting or `("", " ")` when converting as pure
string on a single line

the meat of `nuon.rs` is now the `value_to_string` recursive function:
- takes the depth and the indent string
- adds correct newlines, space separators and indentation to the output
- calls itself with the same indent string but `depth + 1` to increase
the indentation by one level
- i used the `nl`, `idt`, `idt_po` (**i**n**d**en**t** **p**lus **o**ne)
and `idt_pt` (**i**n**d**en**t** **p**lus **t**wo) to make the
`format!`s easier to read

# User-Facing Changes
users can now
- control the amount and nature of NUON string output indentation with
  - `--indent <number of " " per level>`
  - `--tabs <number of "\t" per level>` 
- use the previous behaviour of `to nuon` with the `--raw` option
- have new examples with `help to nuon`

> **Note**
> the priority order of the options is the following
> 1. `--raw`
> 2. `--tabs`
> 3. `--indent`
>
> the default is `--indent 2`

# Tests + Formatting
### new tests
- tests involving the string output of `to nuon`, i.e. tests not of the
form `... | to nuon | from nuon ...`, now use the `to nuon --raw`
command => this is the smallest change to have the tests pass, as the
new `to nuon --raw` is equivalent to the old `to nuon`
- in `crates/nu-command/src/formats/to/nuon.rs`, the previous example
has been replaced with three examples
  - `[1 2 3] | to nuon` to show the default behaviour
  - `[1 2 3] | to nuon --raw` to show the not-formatted output
- a more complex example with `{date: 2000-01-01, data: [1 [2 3] 4.56]}
| to nuon`
  - the result values have been defined and the `examples` tests pass
 
### dev
- 🟢 `cargo fmt --all`
- 🟢 `cargo clippy --workspace -- -D warnings -D
clippy::unwrap_used -A clippy::needless_collect`
- 🟢 `cargo test --workspace` ~~passes but without
`to_nuon_errs_on_closure`~~ fixed in
0b4fad7eff

# After Submitting
the `to nuon` page would have to be regenerated at some point due to the
new tests

Ls symlink fix (#8276)
# Description

Fixes #6706.

I took a look at this issue and it seems that the issue is because the
path is canonicalized and thus derives to the target. I've tested it
locally by checking if the path is a symlink and acting accordingly to
not canonicalize it and it seems fine.

In current release if the target is deleted but the symlink remains and
one `ls`'s it, it throws a `directory not found` error. But with the fix
it still shows the symlink (with red background, indicating missing
target).

The change I've applied only triggers when `ls` is done on a symlink, on
all other counts it should basically do the same as before.

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`.

An example hook on *Arch Linux*, to find packages that contain the
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
        }
      )
    }
    # ...
```

standard library: use the standard assert and fix test output (#8509)
# Description
## in the `test_dirs` test module
- use the `std assert` function in the `test_dirs` module instead of
`myassert`
- refactor the "test cleaning" in the `clean` command
- allows to clean the tests and then throw a real error in the `catch`
block in case there is an error
- the test still "try"s to `clean` the test directory after the `catch`,
like in a "finally" block
- parse the `catch` error and `error make` a proper one instead of
`debug`ging it => because the `catch` will be triggered as soon as one
error occurs, there will always only be a single error in the tests, so
this does not change the behaviour of failing `dirs` tests!

> **Note**
> i'm not particularly happy with the parsing stage in the `catch`
block.
> however that's the simplest i found to both keep the `try` / `catch`
construct that allows to clean the test directory and have a proper
error at the same time!

## in the global `tests` module
- use `print` instead of `echo` to make sure the log statements show up
during the tests

# User-Facing Changes

# Tests + Formatting

- proper error when a `dirs` error occurs => try with `sd 'assert \(1'

Add rest and glob support to 'open' (#8506)
# Description

This adds two different features to `open`:
* The ability to pass more than one file to `open`.
* Support for using globs in the filenames

`open` will create a list stream and stream the output if there is more
than one file opened

Examples:

```
open file1.csv file2.csv file3.csv
```

```
open *.nu | where $it =~ "echo"
```

# User-Facing Changes

Multi-file and glob support in `open`. Original `open` functionality
should continue as before.

This stopped working
```
let-env NU_LIB_DIRS = [

You have to do this now instead.

In talking with @kubouch, he was saying that the `let-env` version
should keep working. Hopefully it's a small change.

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]
 1 │ {major:2, minor:1, patch:4} | values | each { into string }
   ·                                             ───────┬───────
   ·                                                    ╰── Parsing as a closure, but || is missing
   ╰────
  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...

Allow NU_LIBS_DIR and friends to be const (#8310)
# Description

Allow NU_LIBS_DIR and friends to be const they can be updated within the
same parse pass. This will allow us to remove having multiple config
files eventually.

Small implementation detail: I've changed `call.parser_info` to a
hashmap with string keys, so the information can have names rather than
indices, and we don't have to worry too much about the order in which we
put things into it.

Closes https://github.com/nushell/nushell/issues/8422

# User-Facing Changes

In a single file, users can now do stuff like
```
const NU_LIBS_DIR = ['/some/path/here']
source script.nu
```
and the source statement will use the value of NU_LIBS_DIR declared the
line before.

Currently, if there is no `NU_LIBS_DIR` const, then we fallback to using
the value of the `NU_LIBS_DIR` env-var, so there are no breaking changes
(unless someone named a const NU_LIBS_DIR for some reason).

Add char --list example to char command docs (#8474)
# Description

When using `char`, I somehow missed the `--list` flag (even though it's
of course displayed in the help output). While it's maybe a bit
redundant to have a usage of the flag in the examples, I suspect that I
may not be alone in needing an extra nudge on getting that info 😄

# User-Facing Changes

Just an extra example in the `char` help output.

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.

Disable pipeline echo (#8292)
# Description

Change behavior of block evaluation to not print result of intermediate
commands.
Previously result of every but last pipeline in a block was printed to
stdout, and last one was returned

![image](https://user-images.githubusercontent.com/17511668/222550110-3f62fbed-432c-4b46-b9b1-4cb45a1f893e.png)
With this change results of intermediate pipelines are discarded after
they finish and the last one is returned as before:

![image](https://user-images.githubusercontent.com/17511668/222550346-f1e74f80-f6b6-4aa3-98d6-888ea4cb4915.png)
Now one should use `print` explicitly to print something to stdout

![image](https://user-images.githubusercontent.com/17511668/222923955-fda0d77b-41b4-4f91-a80f-12b0a1880c05.png)

**Note, that this behavior is not limited to functions!** The scope of
this change are all blocks. All of the below are executed as blocks and
thus exibited this behavior in the same way:

![image](https://user-images.githubusercontent.com/17511668/222924062-342c15de-4273-4bf5-8b39-fe6e3aa96076.png)

With this change outputs for all types of blocks are cleaned:

# User-Facing Changes

Additional flags for commands from csv and from tsv (#8398)
# Description

Resolves issue #8370

Adds the following flags to commands `from csv` and `from tsv`:
- `--flexible`: allow the number of fields in records to be variable
- `-c --comment`: a comment character to ignore lines starting with it
- `-q --quote`: a quote character to ignore separators in strings,
defaults to '\"'
- `-e --escape`: an escape character for strings containing the quote
character

Internally, the `Value` struct has an additional helper function
`as_char` which converts it to a single `char`

# User-Facing Changes

The single quoted string `'\t'` can no longer be used as a parameter for
the flag `--separator '\t'` as it is interpreted as a two-character
string. One needs to use from now on the flag with a double quoted
string like so: `-s "\t"` which correctly interprets the string as a
single `char`.

Add -i flag back to get and select (#8488)
https://github.com/nushell/nushell/pull/8379 removed the `-i` flag from
`get` and `select` because the new `?` functionality covers most of the
same use cases. However, https://github.com/nushell/nushell/issues/8480
made me realize that `-i` is still useful when dealing with cell paths
in variables.

This PR re-adds the `-i` flag to `get` and `select`. It works by just
marking every member in the cell path as optional, which will behave
_slightly_ differently than `-i` used to (previously it would suppress
any errors, even type errors) but IMO that's OK.

Escape will now escape paths with '=' in them (#8485)
# Description

Fixes the issue where there is no way to escape `FOO=BAR` in a way that
treats it as a file path/executable name. Previously `^FOO=BAR` would be
handled as an environment shorthand. Now, environment shorthands are not
allowed to start with `^`. To create an environment shorthand value that
uses `^` as the first character of the environment variable name, use
quotes, eg `"^FOO"=BAR`

variables any more</strong> (unless you want to call other methods on
them)</li>
<li>Introduced the <code>Mock::remove</code> and
<code>Mock::remove_async</code> methods to remove mocks on demand</li>
</ul>
<h2>Major changes since 0.31</h2>
<ul>
<li>Tests can now run in parallel</li>
<li>Support for HTTP2</li>
<li>An async interface for all actions (though the sync interface is
also available)</li>
<li>Mock multiple server/hosts at the same time</li>

<h2>Migrating to the new API</h2>
<p>Legacy API:</p>
<pre lang="rust"><code>let m1 = mockito::mock(&quot;GET&quot;,
&quot;/hello&quot;).with_body(&quot;hello&quot;).create();
let m2 = mockito::mock(&quot;GET&quot;,
&quot;/bye&quot;).with_body(&quot;bye&quot;).create();
<p>// Use one of these to configure your client
let host = mockito:server_address();
let url = mockito::server_url();
</code></pre></p>
<p>New API:</p>
<pre lang="rust"><code>let mut server = mockito::Server::new();
server.mock(&quot;GET&quot;,
&quot;/hello&quot;).with_body(&quot;hello&quot;).create();
server.mock(&quot;GET&quot;,
&quot;/bye&quot;).with_body(&quot;bye&quot;).create();
<p>// Use one of these to configure your client
let host = server.host_with_port();
let url = server.url();
</code></pre></p>
<blockquote>
<p>If you can't migrate to the new API in one go, consider using version
0.32.5, which supports both the legacy API as well as the new API.</p>
</blockquote>
<h2>Migrating to the async API</h2>
<p>In order to write async tests, you'll need to use the
<code>_async</code> methods:</p>

make better usage of error value in catch block (#8460)
# Description

Fixes: #8402  #8391

The cause of these issue if when we want to evaluate a expression with
`Value::Error`, nushell show error immediately. To fix the issue, we can
wrap the `Value::Error` into a `Value::Record`. So user can see the
message he want.

# User-Facing Changes

Before
```
❯ try { 1 / 0 } catch {|e| echo $"error is ($e)"}
Error: nu:🐚:division_by_zero

  × Division by zero.
   ╭─[entry #2:1:1]
 1 │ try { 1 / 0 } catch {|e| echo $"error is ($e)"}
   ·         ┬
   ·         ╰── division by zero
   ╰────
```

After
```
❯ try { 1 / 0 } catch {|e| echo $"error is ($e)"}
error is {msg: Division by zero., debug: DivisionByZero { span: Span { start: 43104, end: 43105 } }, raw: DivisionByZero { sp
an: Span { start: 43104, end: 43105 } }}
```

As we can see, error becomes a record with `msg`, `debug`, `raw`
columns.
1. msg column is a user friendly message.
2. debug column is more about `Value::Error` information as a string.
3. raw column is a `Value::Error` itself, if user want to re-raise the
error, just use `$e | get raw`

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: 1} {foo: 2} {}].foo
Error: nu:🐚:column_not_found

  × Cannot find column
   ╭─[entry #30:1:1]

   ·                     │   ╰── cannot find column 'foo'
   ·                     ╰── value originates here

╰───┴───╯
〉[{foo: 1} {foo: 2} {}].foo?.2 | describe
nothing

〉[a b c].4? | describe
nothing

〉[{foo: 1} {foo: 2} {}] | where foo? == 1
╭───┬─────╮
│ # │ foo │
├───┼─────┤
│ 0 │   1 │
╰───┴─────╯
```

# 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.

DOC: make the README of the standard library clearer (#8465)
Should close #8444.

# Description
as asked by @presidento, i've used a generic command to run the tests.

i've also transformed the "a concrete example" sections into quote
blocks to make them stand out less.
not sure about that one, please tell me what you think 😋 

i think a small example is always helpfull, maybe some work has to be
done to make it better 💪

# User-Facing Changes
hopefully a slightly clearer README for the standard library

Start grouping parsing of values better (#8470)
# Description

This starts working on refactoring the parser to no longer use
SyntaxShape when making parsing decisions about values. This PR covers
grouping a few of the steps in `parse_value` to key off the first
character for what group of parsing steps it should use.

std.nu: Rewrite assert method (#8405)
It is a common pattern to add message to assert.
Also the error message was not so helpful. (See the difference in the

Fix ls behaviour when directory is empty (#8439)
Prior to this PR, `ls` would return `nothing` in an empty directory.
After this PR, it returns an empty `List`. This makes the behaviour of
`ls` more consistent and easier to reason about (IMO).

This was prompted by a user noticing that `ls | where size == 0KB and
type == file` breaks when run in an empty directory:

```
  × Input type not supported.
   ╭─[entry #12:1:1]
 1 │ ls | where size == 0KB and type == file
   · ─┬   ──┬──
   ·  │     ╰── only list, binary, raw data or range input data is supported
   ·  ╰── input type: nothing
   ╰────
```

If people agree with this change, let's wait until after the 0.77
release so we have a bit more time to test it.

Modify reject algorithm for identical elements (#8446)
# Description

The correction made here concerns the issue #8431. Indeed, the algorithm
initially proposed to remove elements of a `vector` performed a loop
with `remove` and an incident therefore appeared when several values
were equal because the deletion was done outside the length of the
vector:
```rust
let mut found = false;
for (i, col) in cols.clone().iter().enumerate() {
    if col == col_name {
        cols.remove(i);
        vals.remove(i);
        found = true;
    }
}

```

Then, `[[a, a]; [1, 2]] | reject a: ` gave `thread 'main' panicked at
'removal index (is 1) should be < len (is 1)',
crates/nu-protocol/src/value/mod.rs:1213:54`.

The proposed correction is therefore the implementation of the
`retain_mut` utility dedicated to this functionality.

```rust
let mut found = false;
let mut index = 0;
cols.retain_mut(|col| {
    if col == col_name {
        found = true;
        vals.remove(index);
        false
    } else {
        index += 1;
        true
    }
});
```

Disable alias recursion (#8397)
# Description

Prevents alias from aliasing itself. It allows a commonly requested
pattern similar to `alias ls = ls -l`.

One small issue is that the syntax highlighting is a bit off:

Box ShellError in Value::Error (#8375)
# Description

Our `ShellError` at the moment has a `std::mem::size_of<ShellError>` of
136 bytes (on AMD64). As a result `Value` directly storing the struct
also required 136 bytes (thanks to alignment requirements).

This change stores the `Value::Error` `ShellError` on the heap.

Pro:
- Value now needs just 80 bytes
- Should be 1 cacheline less (still at least 2 cachelines)

Con:
- More small heap allocations when dealing with `Value::Error`
  - More heap fragmentation
  - Potential for additional required memcopies

# Further code changes

Includes a small refactor of `try` due to a type mismatch in its large
match.

# User-Facing Changes

None for regular users.

Plugin authors may have to update their matches on `Value` if they use
`nu-protocol`

Needs benchmarking to see if there is a benefit in real world workloads.
**Update** small improvements in runtime for workloads with high volume
of values. Significant reduction in maximum resident set size, when many
values are held in memory.

add dirs command to std lib (#8368)
# Description

Prototype replacement for `enter`, `n`, `p`, `exit` built-ins

# Tests + Formatting

Haven't even looked at stdlib `tests.nu` yet.

Other todos:
* address module todos.
* integrate into std lib, rather than as standalone module. Somehow
arrange for `use .../standard_library/std.nu` to load this module
without having to put all the source in `std.nu`?
*  Maybe command should be `std dirs ...`?   
* what else do `enter` and `exit` do that this should do? Then deprecate
those commands.

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

Hack around bad binary viewing logic (#8399)
# Description

This works around a bug introduced by #8058 

We should revisit the original fix, as it makes some assumptions about
how stdout redirection is used by `table`. We use the stdout by default
for table regularly during a repl session, so we should instead
special-case case for handling externals.

# User-Facing Changes

Restores the original default `table` behaviour for binary data

Remove get -i from default env file (#8390)
This is a follow-up from https://github.com/nushell/nushell/pull/8173,
which was merged shortly after the 0.76 release. That PR changed
`default_env.nu` so that the user's home folder is displayed as `~` in
the left prompt. It did so using `get -i`.

This PR just rewrites the Nu code from
https://github.com/nushell/nushell/pull/8173 to use `try`/`catch`
instead of `-i`, which will make it easier to remove the `-i` flags from
`get` and `select` eventually (see
https://github.com/nushell/nushell/pull/8379).

I would like to merge this before the 0.77 release, so we don't end up
with lots of `env.nu` files using `get -i` out in the wild.

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
```

Revert to notify v4 (#8367)
This reverts https://github.com/nushell/nushell/pull/8114 which upgraded
to `notify` (a file watching crate used by the `watch` command) v5.

`notify` v5 has several breaking changes and it's much harder to use. It
no longer includes debouncing of file system events, which I think is
essential functionality for `watch`. @WindSoilder was going to try
writing our own debouncing functionality but I don't think he had time
to finish it.

@WindSoilder Is it OK if we revert this for the 0.77 release (March 14)?
We can try again for 0.78

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.

# Description
this PR adds the `path add` command to
`crates/nu-utils/standard_library/std.nu`
- this comes from frequent questions over on the discord server, about
how to add directories to the `PATH`
- this is greatly inspired from the [original
`path-add`](https://discord.com/channels/601130461678272522/615253963645911060/1081206660816699402)
from @melMass
- allows to prepend and append a variable number of directories to the
`PATH`
- i've added a description with an example
- i've added tests in `crates/nu-utils/standard_library/tests.nu` that
hopefully covers all the features

# User-Facing Changes

Fix 8244 -- store timestamps with nanosecond resolution (consistently) (#8337)
# Description

Fix for data ambiguity noted in #8244.

Basic change is to use nanosecond resolution for unix timestamps (stored
in type Int). Previously, a timestamp might have seconds, milliseconds
or nanoseconds, but it turned out there were overlaps in data ranges
between different resolutions, so there wasn't always a unique mapping
back to date/time.

Due to higher precision, the *range* of dates that timestamps can map to
is restricted. Unix timestamps with seconds resolution and 64 bit
storage can cover all dates from the Big Bang to eternity. Timestamps
with seconds resolution and 32 bit storage can only represent dates from
1901-12-13 through 2038-01-19. The nanoseconds resolution and 64 bit
storage used with this fix can represent dates from 1677-09-21T00:12:44
to 2262-04-11T23:47:16, something of a compromise.

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

## `<datetime> | into int`
Converts to nanosecond resolution
```rust
〉date now | into int
1678084730502126846
```
This is the number of non-leap nanoseconds after the unix epoch date:
1970-01-01T00:00:00+00:00.

Conversion fails for dates outside the supported range:
```rust
〉1492-10-12 | into int
Error: nu:🐚:incorrect_value

  × Incorrect value.
   ╭─[entry #51:1:1]
 1 │ 1492-10-12 | into int

   ·                  ╰── DateTime out of timestamp range 1677-09-21T00:12:43 and 2262-04-11T23:47:16
   ╰────


```

## `<int> | into datetime`
Can no longer fail or produce incorrect results for any 64-bit input:
```rust
〉0 | into datetime 
Thu, 01 Jan 1970 00:00:00 +0000 (53 years ago)
〉"7fffffffffffffff" | into int -r 16 | into datetime
Fri, 11 Apr 2262 23:47:16 +0000 (in 239 years)
〉("7fffffffffffffff" | into int -r 16) * -1 | into datetime
Tue, 21 Sep 1677 00:12:43 +0000 (345 years ago)
```

## `<date> | date to-record` and `<date> | date to-table`
Now both have a `nanosecond` field.  
```rust
〉"7fffffffffffffff" | into int -r 16 | into datetime | date to-record
╭────────────┬───────────╮
│ year       │ 2262      │

╰────────────┴───────────╯
〉"7fffffffffffffff" | into int -r 16 | into datetime | date to-table
╭───┬──────┬───────┬─────┬──────┬────────┬────────┬────────────┬──────────╮

╰───┴──────┴───────┴─────┴──────┴────────┴────────┴────────────┴──────────╯
```

This change was not mandated by the OP problem, but it is nice to be
able to see the nanosecond bits that were present in Nushell `date` type
all along.

Add SSL tests for http get (#8327)
This PR adds tests to confirm that:
1. `http get` does the right thing (bail) when it encounters common SSL
errors
2. the `--insecure` flag works to ignore SSL errors

It's prompted by #8098, where `--insecure` stopped working and we didn't
notice until it was reported by a user.

## Deets + considerations

This PR uses [badssl.com](https://badssl.com/), a very handy website
affiliated with the Google Chrome team. The badssl authors mention that
stability is not guaranteed:

> Most subdomains are likely to have stable functionality, but anything
could change without notice.

I suspect that the badssl.com subdomains I've chosen will be stable
enough in practice. Can revisit this if the tests end up being flaky.

This PR does mean our tests are now making an external network call...
which I _think_ is OK. Our CI isn't exactly designed for offline
machines; test runners already have to download a bunch of crates etc. I
think the new tests are quick enough:

Fix to json for SQLite databases (#8343)
Fixes #8341. 

The `CustomValue::to_json()` function is an odd duck; it defaults to
returning `null`, and no `CustomValue` implementations override it to do
anything useful. I forgot to implement `to_json()` for `SQLiteDatabase`,
so `open foo.db | to json` was returning `null`.

To fix this, I've removed `CustomValue::to_json()` and now `to json`
will collect a `CustomValue` into a regular `Value` before doing a JSON
conversion.

Document and critically review ShellError variants - Ep. 3 (#8340)
Continuation of #8229 and #8326

# 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.

<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>

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

```
and we can check that these are "true" results and not just string, e.g.
```bash
>_ $nu.scope.commands | where name == merge | get examples.0.result.0 | describe
table<name: string, index: int>
```
### ...with a command without any example: `open`
```bash
>_ $nu.scope.commands | where name == open | get examples.0 | reject description | table --expand
╭───┬──────────────────────────────────────┬────────╮
│ # │               example                │ result │
├───┼──────────────────────────────────────┼────────┤
│ 0 │ open myfile.json                     │        │
│ 1 │ open myfile.json --raw               │        │
│ 2 │ 'myfile.txt' | open                  │        │
│ 3 │ open myfile.txt --raw | decode utf-8 │        │
╰───┴──────────────────────────────────────┴────────╯
```
and same thing, we can check that there is `$nothing` in this last
command
```bash
>_ $nu.scope.commands | where name == open | get examples.0.result.0 | describe
table<name: string, index: int>
```

# Tests + Formatting
- ✔️ `cargo fmt --all`
- ✔️ `cargo clippy --workspace -- -D warnings -D
clippy::unwrap_used -A clippy::needless_collect`
- ✔️ `cargo test --workspace` (~~currently running~~)

# After Submitting
the documentation would have to be regenerated!

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:

Update the command 'version'. (#8312)
# Description

No real changes, just some cleanup while I was looking at the code of
the command.

# User-Facing Changes

Remove the attribute 'pkg_version', since it's already exposed through
'version'.

# 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.

README for nu-json. Related to nushell/nushell#8253 (#8289)
I propose to add such a README file for the nu-json crate.
The crate is good, it is used also by others. However, on crates.io [its
page](https://crates.io/crates/nu-json) looks uninformative.
