# Description
This PR adds the `mime-type` to the `type` column if you add the
`--mime-type(-m)` flag to `ls`.

# User-Facing Changes
If you specify the `-m` flag, you get the "guessed at" mime type. The
guess is based on the file name and uses this crate
https://docs.rs/mime_guess/latest/mime_guess/ for the guessing.
Part of issue #7612 and and #7524
There's some debate on if the `mime-type` should be added to the `type`
column or if there should be a separate `mime` column. I tend to lean on
the side of `type` since it's technically a type and it's only in that
column if you ask it to be there. Also, I'd prefer to reuse a column
rather than having a list of sprawling columns. Also, as @KodiCraft
suggested, there is precedence as with `ls -d` where the summed size is
in the size column.
I could go either way and if someone wants to create a `mime` column,
we'd probably accept it.

Fix and Allow Number and Boolean type to be key in Yaml .
For example :
`"200 : " | from yaml` not allowed because of Number key type.
PR allow , we can use Boolean and Number for key.
For example :
`"true : false" | from yaml`
`"5050 : it is number" | from yaml`
Fixes#7222 .
ref #7598
To be honest I was not able to obtain such results in basic mode as you
@rgwood.
But I've got it in `table -e`.
So this must fix the `table -e` wrapping.
Could you verify if it got fixed?

I tend to think it must be addressed.
But I'd verify it @rgwood.
PS: I've noticed how `table -e` and `table` with the same width wraps a
bit differently sometimes. (I guess it also must be addressed......)

# Description
Inspired by #7592
For brevity use `Value::test_{string,int,float,bool}`
Includes fixes to commands that were abusing `Span::test_data` in their
implementation. Now the call span is used where possible or the explicit
`Span::unknonw` is used.
## Command fixes
- Fix abuse of `Span::test_data()` in `query_xml`
- Fix abuse of `Span::test_data()` in `term size`
- Fix abuse of `Span::test_data()` in `seq date`
- Fix two abuses of `Span::test_data` in `nu-cli`
- Change `Span::test_data` to `Span::unknown` in `keybindings listen`
- Add proper call span to `registry query`
- Fix span use in `nu_plugin_query`
- Fix span assignment in `select`
- Use `Span::unknown` instead of `test_data` in more places
## Other
- Use `Value::test_int`/`test_float()` consistently
- More `test_string` and `test_bool`
- Fix unused imports
# User-Facing Changes
Some commands may now provide more helpful spans for downstream use in
errors
# Description
The message reads "You must use one of the following subcommands. Using
this command as-is will only produce this help message." and is added to
commands like `into`, `bytes`, `str`, etc.

Closes#7572 by adding a cache for compiled regexes of type
`Arc<Mutex<LruCache<String, Regex>>>` to `EngineState` .
The cache is limited to 100 entries (limit chosen arbitrarily) and
evicts least-recently-used items first.
This PR makes a noticeable difference when using regexes for
`color_config`, e.g.:
```bash
#first set string formatting in config.nu like:
string: { if $in =~ '^#\w{6}$' { $in } else { 'white' } }`
# then try displaying and exploring a table with many strings
# this is instant after the PR, but takes hundreds of milliseconds before
['#ff0033', '#0025ee', '#0087aa', 'string', '#4101ff', '#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff', '#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff', '#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff', '#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff','#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff','#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff','#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff','#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff','#ff0033', '#0025ee', '#0087aa', 'string', '#6103ff']
```
## New dependency (`lru`)
This uses [the popular `lru` crate](https://lib.rs/crates/lru). The new
dependency adds 19.8KB to a Linux release build of Nushell. I think this
is OK, especially since the crate can be useful elsewhere in Nu.

# Description
Certain commands that operate on tables also work on bare records, but
their type sig didn't reflect that. This corrects this.
I did not fix certain commands which, I feel, currently give unintended
behaviour when given plain records. These are `sort-by` and `uniq-by`.
Also corrected the wording of some stuff in headers.rs, and removed a
wrong comment in insert.rs.

# Description
* I was dismayed to discover recently that UnsupportedInput and
TypeMismatch are used *extremely* inconsistently across the codebase.
UnsupportedInput is sometimes used for input type-checks (as per the
name!!), but *also* used for argument type-checks. TypeMismatch is also
used for both.
I thus devised the following standard: input type-checking *only* uses
UnsupportedInput, and argument type-checking *only* uses TypeMismatch.
Moreover, to differentiate them, UnsupportedInput now has *two* error
arrows (spans), one pointing at the command and the other at the input
origin, while TypeMismatch only has the one (because the command should
always be nearby)
* In order to apply that standard, a very large number of
UnsupportedInput uses were changed so that the input's span could be
retrieved and delivered to it.
* Additionally, I noticed many places where **errors are not propagated
correctly**: there are lots of `match` sites which take a Value::Error,
then throw it away and replace it with a new Value::Error with
less/misleading information (such as reporting the error as an
"incorrect type"). I believe that the earliest errors are the most
important, and should always be propagated where possible.
* Also, to standardise one broad subset of UnsupportedInput error
messages, who all used slightly different wordings of "expected
`<type>`, got `<type>`", I created OnlySupportsThisInputType as a
variant of it.
* Finally, a bunch of error sites that had "repeated spans" - i.e. where
an error expected two spans, but `call.head` was given for both - were
fixed to use different spans.

This PR changes `to text` so that when given a `ListStream`, it streams
the incoming values instead of collecting them all first.
The easiest way to observe/verify this PR is to convert a list to a very
slow `ListStream` with `each`:
```bash
ls | get name | each {|n| sleep 1sec; $n} | to text
```
The `to text` output will appear 1 item at a time.
# Description
Prevent a situation where a `def` can't be run due to a poor choice of

Cross-compiling Nu can be a little tricky due to dependencies. This PR
makes it easy to use [`cross-rs`](https://github.com/cross-rs/cross), a
popular tool for cross-compiling Rust code using Docker:
```bash
cross build --target aarch64-unknown-linux-musl --release
```
I find this useful for compiling ARM binaries from x64. Easy to add more
target triples later as needed.

# Description
Currently, `filesize_format`/`filesize_metric` conflicts are resolved as
follows: if the `filesize_format` ends in "ib", then that overrides
`filesize_metric`, otherwise, `filesize_metric` overrides
`filesize_format`. This removes this difficult-to-predict asymmetric
behaviour, and makes it so that `filesize_metric` always overrides
`filesize_format`.
This also adds tests for `$env.config.filesize.format` and
`$env.config.filesize.metric` values.
REMINDER: `filesize_metric` means "increments of 1000", and refers to
KB-MB-GB-TB etc.

`proptest` caught a failing test condition for `&&` as a literal string. It requires a quotation to be parsed correctly by current `from nuon`
https://github.com/nushell/nushell/actions/runs/3753242377/jobs/6376308675
The change in the parser that now returns an error was introduced by https://github.com/nushell/nushell/pull/7241
This in theory doesn't have to be an error (it is a diagnostic for nushell code) but it is probably better safe than sorry to require quotation here.
- Add a test for `&&` in `to nuon` from proptest fail
- Fix `to nuon` generating invalid `&&` literal
- Add a test for `,` in `to nuon`/`from nuon` cycle
- Bonus: should already be properly quoted
Just change the description of the `--stdin` flag as shown in `nu
--help`:
"redirect the stdin" -> "redirect standard input to a command (with
`-c`) or a script file"
The old description was a little too terse and I had to look in the code
to see what it was doing.
`table` handles slow `ListStream`s in a special way: every 100 items, it
checks whether 1 second has elapsed since the last table page, and if so
it outputs a new page with all the items in its buffer.
**I would like to remove the "every 100 items" condition and always
output whatever we have if a second has elapsed.** I think this will be
a better user experience for very slow streams.
As a motivating example, imagine tailing a log file and doing some
string parsing/projection on each line. The user will be really annoyed
if they have to wait for 100 lines to be written to the log before
seeing new results!
I did some quick performance measurements with Criterion, and the
elapsed-time check takes about 16ns on my machine (Linux, 12900k). I
think the performance impact of checking that for every item will be
negligible.
