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.
   ╭─[entry #3:1:1]

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 ;) ):

Switch let/let-env family to init with math expressions (#8545)
# Description

This is an experiment to see what switching the `let/let-env` family to
math expressions for initialisers would be like.

# User-Facing Changes

This would require any commands you call from `let x = <command here>`
(and similar family) to call the command in parentheses. `let x = (foo)`
to call `foo`.

# 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

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

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

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
        }
      )
    }
    # ...
```

# User-Facing Changes
- Add a `command_not_found` function to `$env.config.hooks`.

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.

Revert "Allow NU_LIBS_DIR and friends to be const" (#8501)
Reverts nushell/nushell#8310

In anticipation that we may want to revert this PR. I'm starting the
process because of this issue.

This stopped working
```
let-env NU_LIB_DIRS = [
    ($nu.config-path | path dirname | path join 'scripts')
    'C:\Users\username\source\repos\forks\nu_scripts'
    ($nu.config-path | path dirname)
]
```
You have to do this now instead.
```
const NU_LIB_DIRS = [
    'C:\Users\username\AppData\Roaming\nushell\scripts'
    'C:\Users\username\source\repos\forks\nu_scripts'
    'C:\Users\username\AppData\Roaming\nushell'
]
```

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)

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 😄

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

With this change results of intermediate pipelines are discarded after
they finish and the last one is returned as before:

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.

Bump mockito from 0.32.5 to 1.0.0 (#8426)
Bumps [mockito](https://github.com/lipanski/mockito) from 0.32.5 to
1.0.0.
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/lipanski/mockito/releases">mockito's
releases</a>.</em></p>
<blockquote>
<h2>1.0.0</h2>
<p>🎈 7 years and 63 releases later, it's finally time for the
1.0 🎈</p>
<h2>Changes</h2>
<ul>
<li><strong>[Breaking]</strong> The legacy interface was removed in this
version</li>
<li><strong>[Breaking]</strong> <code>Mock::with_body_from_fn</code> was
renamed to <code>Mock::with_chunked_body</code> - the former is still
supported with a deprecation warning</li>
<li>Mocks are only cleared when the server is dropped, not when the mock
is dropped - this means you <strong>don't have to assign mocks to
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>
</ul>
<p>For a list of all the changes please check the <a
href="https://github.com/lipanski/mockito/releases">release log</a>.</p>
<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

nothing

〉[a b c].4? | describe

〉[{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.

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:

![alias_itself_no_color](https://user-images.githubusercontent.com/25571562/224545129-8a3ff535-347b-4a4e-b686-11493bb2a33b.png)

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.
