# Description
This PR changes the old performance logging with `Instant` timers. I'm
not sure if this is the best way to do it but it does help reveal where
time is being spent on startup. This is what it looks like when you
launch nushell with `cargo run -- --log-level info`. I'm using the
`info` log level exclusively for performance monitoring at this point.

## After Startup
Since you're in the repl, you can continue running commands. Here's the
output of `ls`, for instance.

Note that the above screenshots are in debug mode, so they're much
slower than release.

# Description
This PR shows the startup time and decreases the banner. This startup
time output can be disabled with the `show_banner: false` setting in the
config. This is the startup in debug mode.

On my mac in release mode
```
Startup Time: 368ms 429µs 83ns
```
On my mac without a config as `nu --config foo --env-config foo`
```
Startup Time: 11ms 663µs 791ns
```
I could really go either way on this. If people don't like this change,
we don't have to merge it.

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>

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)

# 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
![nu_pb01](https://user-images.githubusercontent.com/38369407/210298647-07ee55ea-e751-41b1-a84d-f72ec1f6e9e5.jpg)
but if we don't then we just show the stats like: data already saved,
bytes per second, and time lapse.
![nu_pb02](https://user-images.githubusercontent.com/38369407/210298698-1ef65f51-40cc-4481-83de-309cbd1049cb.jpg)

Please let me know If I need to make any changes and I will be happy to
do it.
# User-Facing Changes
A new flag (`--progress` `-p`) was added to the `save` command
Examples:
```nu
fetch https://github.com/torvalds/linux/archive/refs/heads/master.zip | save --progress -f main.zip
fetch https://releases.ubuntu.com/22.04.1/ubuntu-22.04.1-desktop-amd64.iso | save --progress -f main.zip

This PR sets up [Criterion](https://github.com/bheisler/criterion.rs)
for benchmarking in the main `nu` crate, and adds some simple parser
benchmarks.
To run the benchmarks, just do `cargo bench` or `cargo bench -- <regex
matching benchmark names>` in the repo root:
```bash
〉cargo bench -- parse
...
Running benches/parser_benchmark.rs (target/release/deps/parser_benchmark-75d224bac82d5b0b)
parse_default_env_file time: [221.17 µs 222.34 µs 223.61 µs]
Found 8 outliers among 100 measurements (8.00%)
5 (5.00%) high mild
3 (3.00%) high severe
parse_default_config_file
time: [1.4935 ms 1.4993 ms 1.5059 ms]
Found 11 outliers among 100 measurements (11.00%)
7 (7.00%) high mild
4 (4.00%) high severe
```
Existing benchmarks from `nu-plugin` have been moved into the main `nu`
crate to keep all our benchmarks in one place.
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
Fixes#7546 's request. I'm unsure, so hopefully someone in charge of
design can chip in.

`open` now opens directories in the default file manager.

# 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.

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
Closes#6909. You can now add closures to your `color_config` themes.
Whenever a value would be printed with `table`, the closure is run with
the value piped-in. The closure must return either a {fg,bg,attr} record
or a color name (`'light_red'` etc.). This returned style is used to
colour the value.
This is entirely backwards-compatible with existing config.nu files.
Example code excerpt:
```
let my_theme = {
header: green_bold
bool: { if $in { 'light_cyan' } else { 'light_red' } }
int: purple_bold
filesize: { |e| if $e == 0b { 'gray' } else if $e < 1mb { 'purple_bold' } else { 'cyan_bold' } }
duration: purple_bold
date: { (date now) - $in | if $in > 1wk { 'cyan_bold' } else if $in > 1day { 'green_bold' } else { 'yellow_bold' } }
range: yellow_bold
string: { if $in =~ '^#\w{6}$' { $in } else { 'white' } }
nothing: white
```

Slightly important notes:
* Some color_config names, namely "separator", "empty" and "hints", pipe
in `null` instead of a value.
* Currently, doing anything non-trivial inside a closure has an
understandably big perf hit. I currently do not actually recommend
something like `string: { if $in =~ '^#\w{6}$' { $in } else { 'white' }
}` for serious work, mainly because of the abundance of string-type data
in the world. Nevertheless, lesser-used types like "date" and "duration"
work well with this.
* I had to do some reorganisation in order to make it possible to call
`eval_block()` that late in table rendering. I invented a new struct
called "StyleComputer" which holds the engine_state and stack of the
initial `table` command (implicit or explicit).
* StyleComputer has a `compute()` method which takes a color_config name
and a nu value, and always returns the correct Style, so you don't have
to worry about A) the color_config value was set at all, B) whether it
was set to a closure or not, or C) which default style to use in those
cases.
* Currently, errors encountered during execution of the closures are
thrown in the garbage. Any other ideas are welcome. (Nonetheless, errors
result in a huge perf hit when they are encountered. I think what should
be done is to assume something terrible happened to the user's config
and invalidate the StyleComputer for that `table` run, thus causing
subsequent output to just be Style::default().)
* More thorough tests are forthcoming - ran into some difficulty using
`nu!` to take an alternative config, and for some reason `let-env config
=` statements don't seem to work inside `nu!` pipelines(???)
* The default config.nu has not been updated to make use of this yet. Do
tell if you think I should incorporate that into this.

## Fix `nu-path` usage in `nu!` testing macro
The `nu-path` crate needs to be properly re-exported so the generated
code is valid if `nu-path` is not present among the dependencies of the
using crate.
Usage of crates in `macro_rules!` macros has to follow the
`$crate::symbol_in_crate` path pattern (With an absolute path-spec also
for macros defined in submodules)
## Move `nu-test-support` to devdeps in `nu-protocol`
Also remove the now unnecessary direct dependency on `nu-path`.
`nu!` macro had to be changed to make it a proper transitive dependency.
# Description
Closes#7059. Rather than generate a new Record each time $env.config is
accessed (as described in that issue), instead `$env.config = ` now A)
parses the input record, then B) un-parses it into a clean Record with
only the valid values, and stores that as an env-var. The reasoning for
this is that I believe `config_to_nu_record()` (the method that performs
step B) will be useful in later PRs. (See below)
As a result, this also "fixes" the following "bug":
```
〉$env.config = 'butts'
$env.config is not a record
〉$env.config
butts
```
~~Instead, `$env.config = 'butts'` now turns `$env.config` into the
default (not the default config.nu, but `Config::default()`, which
notably has empty keybindings, color_config, menus and hooks vecs).~~
This doesn't attempt to fix#7110. cc @Kangaxx-0

This change makes SQLite queries (`open foo.db`, `open foo.db | query db
"select ..."`) cancellable using `ctrl+c`. Previously they were not
cancellable, which made it unpleasant to accidentally open a very large
database or run an unexpectedly slow query!
UX-wise there's not too much to show:

## Notes
I was hoping to make SQLite queries streamable as part of this work, but
I ran into 2 problems:
1. `rusqlite` lifetimes are nightmarishly complex and they make it hard
to create a `ListStream` iterator
2. The functions on Nu's `CustomValue` trait return `Value` not
`PipelineData` and so `CustomValue` implementations can't stream data
AFAICT.

commented out
