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.

# 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

- `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

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)
# 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.

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

All types of blocks (function bodies, closures, `if` branches, `for` and
`loop` bodies e.t.c.) no longer print result of intermediate pipelines.

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
   ╰────

╭───┬───╮

╰───┴───╯
〉[{foo: 1} {foo: 2} {}].foo?.2 | describe
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
    }
});
```

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.

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

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      │
│ month      │ 4         │
│ day        │ 11        │
│ hour       │ 23        │
│ minute     │ 47        │
│ second     │ 16        │
│ nanosecond │ 854775807 │
│ timezone   │ +00:00    │
╰────────────┴───────────╯
〉"7fffffffffffffff" | into int -r 16 | into datetime | date to-table
╭───┬──────┬───────┬─────┬──────┬────────┬────────┬────────────┬──────────╮
│ # │ year │ month │ day │ hour │ minute │ second │ nanosecond │ timezone │
├───┼──────┼───────┼─────┼──────┼────────┼────────┼────────────┼──────────┤
│ 0 │ 2262 │     4 │  11 │   23 │     47 │     16 │  854775807 │ +00:00   │
╰───┴──────┴───────┴─────┴──────┴────────┴────────┴────────────┴──────────╯
```

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.

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

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

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.

_(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

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:
