`help <keyword>` will now search for `<keyword>` in aliases first, then
commands. This matches the way the parser resolves aliases before
commands.

# Description
_(Thank you for improving Nushell. Please, check our [contributing
guide](../CONTRIBUTING.md) and talk to the core team before making major
changes.)_
I opened this PR to unify the run command method. It's mainly to improve
consistency across the tree.

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

# Description
Fix for #7933. I've read through code and found the obvious difference
between them, where `each` command calls eval_with_early_return
e89e734ca2/crates/nu-command/src/filters/each.rs (L158),
while `reduce` command uses eval_block
e89e734ca2/crates/nu-command/src/filters/reduce.rs (L143)
That simple change seems to resolve the problem.
# User-Facing Changes
Allows the use of `return` in reduce closures, as per example in #7933
description. Arguably it's restoring consistency, than changing user
interface.
```
[1, 2] | reduce --fold null { |it, state|
::: if $it == 1 {
::: return 10
::: }
::: return ($it * $state)
::: }
20
```

It's because `do -i` doesn't handles `Pipeline::ListStream`

To fix it, we need to iterate through `ListStream`, check if there is
`Value::Error`. If so, just returns `Pipeline::empty()`

On `cp` commands there were two error which pass error message with
invalid detail about source and destination files . there error were for
Not exist file and Permission denied .
Examples:
Before :
Copy `source_file_valid` to `destination_invalid_dir` throw this error ;
`copy file "/source_file_valid" failed: No such file or directory (os
error 2) `
After this PR it will throw this if destination will be invalid :
`copying to destination "/destination_invalid_dir" failed: No such file
or directory (os error 2) `
it was for Permission denied too .

# Description
Fixes: #7828
We delegate to `save` command to finish redirection, then if it runs to
success, the relative exit code is set to 0. To fix it, in redirection
context, we take exit_code stream before sending it to `save` command,
than manually returns `PipelineData::ExternalStream` to make nushell set
relative code properly.

I noticed that [it's pretty easy to name threads in
Rust](https://doc.rust-lang.org/std/thread/#naming-threads). We might as
well do this; it's a nice quality of life improvement when you're
profiling something and the developers took the time to give threads
names.
Also added/cleaned up some comments while I was in the area.

# Description
Add flags for filtering the output of `glob` by file type. I find myself
occasionally wanting to do this, and getting a file's
[file_type](https://docs.rs/wax/latest/wax/struct.WalkEntry.html#method.file_type)
is presumably fast to do as it doesn't have to go through the fallible
metadata method.
The design of the signature does concern me; it's not as readable as a
filter or "include" type list would be. They have to be filtered one by
one, which can be annoying if you only want files `-D -S`, or only want
folders `-F -S`, or only want symlinks `--butwhy?`. I considered
SyntaxShape::Keyword for this but I'll just defer to comments on this PR
if they pop up.
I'd also like to bring up performance since including these flags
technically incurs a `.filter` penalty on all glob calls, which could be
optimized out if we added a branch for the no-filters case. But in
reality I'd expect the file system to be the bottleneck and the flags to
be pretty branch predictor friendly, so eh
# User-Facing Changes
Three new flags when using `glob` and a slightly more cluttered help
page. No breaking changes, I hope.

Improve doc to clarify current behavior.
To flatten all nested levels, we can use the following custom

```
def flatten_all_nested [input_table: any] {
mut input = $input_table
mut flattened = ($input | flatten --all)
while $input != $flattened {
$input = $flattened
$flattened = ($input | flatten --all)
}
$flattened

changelog</a>.</em></p>
<blockquote>
<h1>Release rayon 1.6.1 (2022-12-09)</h1>
<ul>
<li>Simplified <code>par_bridge</code> to only pull one item at a time
from the iterator,
without batching. Threads that are waiting for iterator items will now
block
appropriately rather than spinning CPU. (Thanks <a
href="https://github.com/njaard"><code>@njaard</code></a>!)</li>
<li>Added protection against recursion in <code>par_bridge</code>, so
iterators that also
invoke rayon will not cause mutex recursion deadlocks.</li>
</ul>
<h1>Release rayon-core 1.10.1 (2022-11-18)</h1>
<ul>
<li>Fixed a race condition with threads going to sleep while a broadcast
starts.</li>
</ul>
<h1>Release rayon 1.6.0 / rayon-core 1.10.0 (2022-11-18)</h1>
<ul>
<li>The minimum supported <code>rustc</code> is now 1.56.</li>
<li>The new <code>IndexedParallelIterator::fold_chunks</code> and
<code>fold_chunks_with</code> methods
work like <code>ParallelIterator::fold</code> and <code>fold_with</code>
with fixed-size chunks of
items. This may be useful for predictable batching performance, without
the
allocation overhead of
<code>IndexedParallelIterator::chunks</code>.</li>
<li>New "broadcast" methods run a given function on all
threads in the pool.
These run at a sort of reduced priority after each thread has exhausted
their
local work queue, but before they attempt work-stealing from other
threads.
<ul>
<li>The global <code>broadcast</code> function and
<code>ThreadPool::broadcast</code> method will
block until completion, returning a <code>Vec</code> of all return
values.</li>
<li>The global <code>spawn_broadcast</code> function and methods on
<code>ThreadPool</code>, <code>Scope</code>,
and <code>ScopeFifo</code> will run detached, without blocking the
current thread.</li>
</ul>
</li>
<li>Panicking methods now use <code>#[track_caller]</code> to report the
caller's location.</li>
<li>Fixed a truncated length in <code>vec::Drain</code> when given an
empty range.</li>
</ul>

# Updated description by @rgwood
This PR changes `fetch` to `http get` and `post` to `http post`. `fetch`
and `post` are now deprecated. [I surveyed people on
Discord](https://discord.com/channels/601130461678272522/601130461678272524/1065706282566307910)
and users strongly approved of this change.
# Original Description
This PR is related to #2741 and my first pull request in rust :)
Implemented a new http mod to better http support and alias `fetch` and
`post` commands to `http get` and `http post` respectively.
# User-Facing Changes
Users will be able to use HTTP method via http command, for example
``` shell
> http get "https://www.example.com"
<!doctype html>
<html>
...
```
# Description
This PR fixes the signature display when running `help commands`. Before
this PR, there were leading spaces in the signatures column. Now,
they're left aligned for a cleaner look.

This is an attempt to implement a new `Value::LazyRecord` variant for
performance reasons.
`LazyRecord` is like a regular `Record`, but it's possible to access
individual columns without evaluating other columns. I've implemented
`LazyRecord` for the special `$nu` variable; accessing `$nu` is
relatively slow because of all the information in `scope`, and [`$nu`
accounts for about 2/3 of Nu's startup time on
Linux](https://github.com/nushell/nushell/issues/6677#issuecomment-1364618122).
### Benchmarks
I ran some benchmarks on my desktop (Linux, 12900K) and the results are
very pleasing.
Nu's time to start up and run a command (`cargo build --release;
hyperfine 'target/release/nu -c "echo \"Hello, world!\""' --shell=none
--warmup 10`) goes from **8.8ms to 3.2ms, about 2.8x faster**.
Tests are also much faster! Running `cargo nextest` (with our very slow
`proptest` tests disabled) goes from **7.2s to 4.4s (1.6x faster)**,
because most tests involve launching a new instance of Nu.
### Design (updated)
I've added a new `LazyRecord` trait and added a `Value` variant wrapping
those trait objects, much like `CustomValue`. `LazyRecord`
implementations must implement these 2 functions:
```rust
// All column names
fn column_names(&self) -> Vec<&'static str>;
// Get 1 specific column value
fn get_column_value(&self, column: &str) -> Result<Value, ShellError>;
```
### Serializability
`Value` variants must implement `Serializable` and `Deserializable`, which poses some problems because I want to use unserializable things like `EngineState` in `LazyRecord`s. To work around this, I basically lie to the type system:
1. Add `#[typetag::serde(tag = "type")]` to `LazyRecord` to make it serializable
2. Any unserializable fields in `LazyRecord` implementations get marked with `#[serde(skip)]`
3. At the point where a `LazyRecord` normally would get serialized and sent to a plugin, I instead collect it into a regular `Value::Record` (which can be serialized)
Previously the group check was only for the current users gid, now we
check against all the users groups.
# Description
Currently when using the `cd` command to enter a directory there was
only a check against the current user id, and exact current group id,
meaning if a directory had a group permission and that group wasn't the
users group it was effectively ignored.
The fix simply implements a check through all the users current groups.

So the following command

Will stream data to `output.txt`
But I'm note sure how to make a proper test for it, so I leave with no
new test cases..
Also rename from `string_binary_list_value_to_bytes ` to
`value_to_bytes` to accepts more Value type.

# Description
Refactor command: "to url" in: "to url query". Changed usage sentence.
Closes: #7495
# User-Facing Changes
Now we get a query string from a record or table by using command: "to
url query".
```
> help to url query
Convert record or table into query string applying percent-encoding.
Usage:
> to url query
Flags:
-h, --help - Display the help message for this command
Signatures:
<record> | to url query -> <string>
<table> | to url query -> <string>
Examples:
Outputs a query string representing the contents of this record
> { mode:normal userid:31415 } | to url query
Outputs a query string representing the contents of this 1-row table
> [[foo bar]; ["1" "2"]] | to url query
Outputs a query string representing the contents of this record
> {a:"AT&T", b: "AT T"} | to url query
```
# Tests + Formatting
Added this test:
```
Example {
description: "Outputs a query string representing the contents of this record",
example: r#"{a:"AT&T", b: "AT T"} | to url query"#,
result: Some(Value::test_string("a=AT%26T&b=AT+T")),
},
```
to ensure percent-encoding.
# After Submitting
If PR is accepted I'll open another PR on documentation to notify
changes on
[this.](https://github.com/nushell/nushell.github.io/blob/main/book/commands/to_url.md)
I have changed `assert!(a == b)` calls to `assert_eq!(a, b)`, which give
better error messages. Similarly for `assert!(a != b)` and
`assert_ne!(a, b)`. Basically all instances were comparing primitives
(string slices or integers), so there is no loss of generality from
special-case macros,
I have also fixed a number of typos in comments, variable names, and a
few user-facing messages.
Closes#6337 and #5366. Prior to this PR, when "shelling out" to cmd.exe
on Windows we were not trimming quotes correctly:
```bash
〉^echo "foo"
\"foo\"
```
After this change, we do:
```bash
〉^echo "foo"
foo
```
### Breaking Change
I ended up removing `dir` from the list of supported cmd.exe internal
commands as part of this PR.
For this PR, I extracted the argument-cleaning-and-expanding code from
`spawn_simple_command()` for reuse in `spawn_cmd_command()`. This means
that we now expand globs, which broke some tests for the `dir` cmd.exe
internal command.
I probably could have kept the tests working, but... tbh, I don't think
it's worth it. I don't want to make the `cmd.exe` functionality any more
complicated than it already is, and calling `dir` from Nu is always
going to be weird+hacky compared to `ls`.

# Description
In bash when a program crashes, it prints the reason for what happened:
```
$ ./division_by_zero
Floating point exception (core dumped)
$ ./segfault
Segmentation fault (core dumped)
```
Nushell always prints the same thing in this case:
```
> ./division_by_zero
nushell: oops, process './division_by_zero' core dumped
Error: nu:🐚:external_command (link)
# etc..
```
This PR adds more detailed error printing, like in bash:
```
> ./division_by_zero
Floating point exception: oops, process './division_by_zero' core dumped
Error: nu:🐚:external_command (link)
# etc..
```
I made this message format as an example:
```
Floating point exception: oops, process './division_by_zero' core dumped
```
Instead of `nushell:` it writes a meaningful message, but I can change
this format as per the suggestions.
I tested the change only on linux, but it should work on other unix
systems.

# Description
Closes#7514.
* For both `encode` and `decode`: add a special case allowing `utf16` as
a valid alias for `utf-16` (just as `utf-8` has `utf8`).
* For `encode` , make it an error when encodings_rs replaces characters
outside the given encoding with HTML entities
* For `encode` , add `-i`/`--ignore-errors` flag to bring back this
behaviour.
Note: `--ignore-errors` does NOT ignore the error for using a wrong
encoding label like `uft8`

# Description
_(Description of your pull request goes here. **Provide examples and/or
screenshots** if your changes affect the user experience.)_
I implemented the status bar we talk about yesterday. The idea was
inspired by the progress bar of `wget`.
I decided to go for the second suggestion by `@Reilly`
> 2. add an Option<usize> or whatever to RawStream (and ListStream?) for
situations where you do know the length ahead of time
For now only works with the command `save` but after the approve of this
PR we can see how we can implement it on commands like `cp` and `mv`
When using `fetch` nushell will check if there is any `content-length`
attribute in the request header. If so, then `fetch` will send it
through the new `Option` variable in the `RawStream` to the `save`.
If we know the total size we show the progress bar
but if we don't then we just show the stats like: data already saved,
bytes per second, and time lapse.
Please let me know If I need to make any changes and I will be happy to
do it.
# User-Facing 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

I am getting some errors and its weird because the errors are showing up
in files i haven't touch. Is this normal?

src/main.rs has a dependency on BufferedReader
which is currently located in nu_command.
I am moving BufferedReader to a more relevant
location (crate) which will allow / eliminate main's dependency
on nu_command in a benchmark / testing environment...
now that @rgwood has landed benches I want
to start experimenting with benchmarks related
to the parser.
For benchmark purposes when dealing with parsing
you need a very simple set of commands that show
how well the parser is doing, in other words
just the core commands... Not all of nu_command...
Having a smaller nu binary when running the benchmark CI
would enable building nushell quickly, yet still show us
how well the parser is performing...
Once this PR lands the only dependency main will have
on nu_command is create_default_context ---
meaning for benchmark purposes we can swap in a tiny
crate of commands instead of the gigantic nu_command
which has its "own" create_default_context...
It will also enable other crates going forward to
use BufferedReader. Right now it is not accessible
to other lower level crates because it is located in a
"top of the stack crate".
# Description
This commit makes the `user` parameter optional in the `fetch` command.
Previously when attempting to _only_ pass a `password`, the command
would ignore authentication. Now when a `user` is not supplied, but a
`password` is, an empty user is implied.
Before this PR, consider the following:
```nushell
fetch -password "mypassword" $url
```
This would result in the `password` parameter being ignored entirely.
Now, with changes made in this PR, consider the same code snippet as
above. The following HTTP header will be used:
```
Authentication: Basic <base64_encode(":{password}")>
```
Note that the `user` field is implied as empty if one is not supplied
when `password` is.
# User-Facing Changes
* `fetch` now supports `password`-only authentication, using an empty
`user` if one is not supplied.

Reasoning:
Most missing math commands are implemented with #7258.
The `meval` crate itself declares that it doesn't strive to stringent
standards (https://docs.rs/meval/latest/meval/#related-projects).
For example no particular special casing or transformations are
performed to ensure numerical stability. It uses the same rust `std`
library functions we use or have access to (and `f64`).
While the command call syntax in nushell may be a bit more verbose,
having a single source of truth and common commands is beneficial.
Furthermore the `math` commands can themselves implement broadcasting
over lists (or table columns).
Closes#7073
Removed dependencies:
- `meval`
- `nom 1.2.4` (duplicate)
User-Facing Changes:
Scripts using `math eval` will break.
We remove a further `eval` like behavior to get results through runtime evaluation (albeit limited in scope)
Tests:
- Updated tests that internally used `math eval`.
- Removed one test that primarily used `math eval` to obtain a result from `str join`
# Description
Refactored the quadratic complexity on `uniq` to use a HashMap, as key I
converted the Value to string.
I tried to use the HashableValue, but it looks it is not very developed
yet and it was getting more complex and difficult.
This improves performance on large data sets.
Fixes https://github.com/nushell/nushell/issues/7477

```
> let data = fetch "https://home.treasury.gov/system/files/276/yield-curve-rates-1990-2021.csv"

```
it keeps original attribute order in Records:
```
> [ {b:2, a:1} {a:1, b:2} ] | uniq
╭───┬───┬───╮
│ # │ b │ a │

Closes#7581.
After this PR, `describe` shows `(stream)` next to input that arrived at
`describe` as a `ListStream`:
```bash
〉ls | describe
table<name: string, type: string, size: filesize, modified: date> (stream)
〉[1 2 3] | each {|i| $i} | describe
list<int> (stream)
```
`describe` must collect all items of the stream to display type
information for lists and tables. If users need to avoid collecting
input, they can use the `-n`/`--no-collect` flag:
```bash
〉[1 2 3] | each {|i| $i} | describe --no-collect
stream
```
I noticed that the help for the `url` command was confusing (it wasn't
clear that `url` is just a base command that does nothing itself) and
the input type was also wrong. Fixed.
Before:
```bash
〉help url
Apply url function.
Search terms: network, parse
Usage:
> url
Subcommands:
url parse - Parses a url
Flags:
-h, --help - Display the help message for this command
Signatures:
<string> | url -> <string>
```
After:
```bash
〉help url
Various commands for working with URLs
You must use one of the following subcommands. Using this command as-is will only produce this help message.
Search terms: network, parse
Usage:
> url
Subcommands:
url parse - Parses a url
Flags:
-h, --help - Display the help message for this command
Signatures:
<nothing> | url -> <string>
```
