Fix hidden env vars not being hidden in closures (#8055)
# Description

This one fixes env not being hidden inside closure, reported in the
conversation under https://github.com/nushell/nushell/issues/6593

https://github.com/nushell/nushell/issues/6593
https://github.com/nushell/nushell/issues/7937 still persist. These
seems a bit more involved and might need hidden env tracking also in the
engine state... I'm not yet sure what's causing it.

Also re-enables some env-related tests and removes unused Value clone.

# User-Facing Changes

Just a bugfix

# Tests + Formatting

Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

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

Improve error when regex rejects pattern. Resolution of #8037 (#8050)
# Description

Improve error when `str replace <pattern>` detects a problem with
<pattern>.

# User-Facing Changes

New "Incorrect value" error:
```
〉 'C:\Users\kubouch' | str replace 'C:\Users' 'foo'
Error: nu:🐚:incorrect_value (link)

  × Incorrect value.
   ╭─[entry #1:1:1]
 1 │  'C:\Users\kubouch' | str replace 'C:\Users' 'foo'
   ·                                   ─────┬────
   ·                                        ╰── Regex error: Parsing error at position 4: Invalid hex escape
   ╰────
```

We could fruitfully replace some of the current uses of
`ShellError::UnsupportedInput` with this error. 'Incorrect value' is
different from 'wrong type'

Benchmark each pipeline element (#7854)
# Description

Adds a `profile` command that profiles each pipeline element of a block
and can also recursively step into child blocks.

# Limitations
* It is implemented using pipeline metadata which currently get lost in
some circumstances (e.g.,
https://github.com/nushell/nushell/issues/4501). This means that the
profiler will lose data coming from subexpressions. This issue will
hopefully be solved in the future.
* It also does not step into individual loop iteration which I'm not
sure why but maybe that's a good thing.

Check ctrl+c when collecting a RawStream (#8020)
I noticed that `open some_big_file | into binary` cannot be cancelled
with `ctrl+c`.

This small PR fixes that by checking `ctrl+c` in
`RawStream::into_bytes()`, and does the same in
`RawStream::into_string()` for good measure.

explain command (#7957)
# Description

The purpose of this PR is to introduce the `inspect` command. A command
that is used to inspect, but not run, a pipeline to ensure everything
looks right. This is meant as a debugging tool. This is some hackery, so
don't laugh. :)

view span & view files commands (#7989)
# Description

This PR does the following:
1. Adds a new command called `view span` - which shows what is at the
location of the span parameters
2. Adds a new command called `view` - which just lists all the `view`
commands.
3. Renames `view-source` to `view source`.
4. Adds a new command called `view files` - which shows you what files
are loaded into nushell's EngineState memory.
5. Added a `Category::Debug` and put these commands (and others) into
it. (`inspect` needs to be added to it, but it's not landed yet)

Spans are important to nushell. One of their uses is to show where
errors are. For instance, in this example, the leader lines pointing to
parts of the command line are able to point to `10`, `/`, and `"bob"`
because each of those items have a span.
```
> 10 / "bob"
Error: nu::parser::unsupported_operation (link)

  × Types mismatched for operation.
   ╭─[entry #8:1:1]

   · ─┬ ┬ ──┬──
   ·  │ │   ╰── string
   ·  │ ╰── doesn't support these values.
   ·  ╰── int
   ╰────
  help: Change int or string to be the right types and try again.
```


# Examples

## view span
Example:
```
> $env.config | get keybindings | first | debug -r
... bunch of stuff
                    span: Span {
                        start: 68065,
                        end: 68090,
                    },
                },
            ],
            span: Span {
                start: 68050,
                end: 68101,
            },
        },
    ],
    span: Span {
        start: 67927,
        end: 68108,
    },
}
```
To view the last span:
```

{
        name: clear_everything
        modifier: control
        keycode: char_l
        mode: emacs
        event: [
            { send: clearscrollback }
        ]
    }
```
> To view the 2nd to last span:
```
view span 68065 68090
{ send: clearscrollback }
```
> To view the 3rd to last span:
```
view span 68050 68101

`entry #x` will be each command you type in the repl (i think). so, it

fix completions PATH vs Path (#8003)
# Description

This PR attempts to fix the completions issue where, on Windows,
completions wouldn't get generated from items in your path environment
variable. This seemed to be down to `PATH` vs `Path`. So, I tried to add
a new function that we can use anywhere to avoid this problem.

Make plugin commands support examples. (#7984)
# Description

As title, we can't provide examples for plugin commands, this pr would
make it possible


# User-Facing Changes

Take plugin `nu-example-1` as example:
```
❯ nu-example-1 -h
PluginSignature test 1 for plugin. Returns Value::Nothing

Usage:
  > nu-example-1 {flags} <a> <b> (opt) ...(rest)

Flags:
  -h, --help - Display the help message for this command
  -f, --flag - a flag for the signature
  -n, --named <String> - named string

Parameters:
  a <int>: required integer value
  b <string>: required string value
  (optional) opt <int>: Optional number
  ...rest <string>: rest value string

Examples:
  running example with an int value and string value
  > nu-example-1 3 bb
```

The examples session is newly added.

## Basic idea behind these changes
when nushell query plugin signatures, plugin just returns it's signature
without any examples, so nushell have no idea about the examples of
plugin commands.
To adding the feature, we just making plugin returns it's signature with
examples.

Before:
```
        1. get signature
         ----------------> 
Nushell ------------------  Plugin
        <-----------------
        2. returns Vec<Signature>
```

After:
```
        1. get signature
        ----------------> 
Nushell ------------------  Plugin
        <-----------------
        2. returns Vec<PluginSignature>
```
        
When writing plugin signature to $nu.plugin-path:
Serialize `<PluginSignature>` rather than `<Signature>`, which would
enable us to serialize examples to `$nu.plugin-path`

## Shortcoming
It's a breaking changes because `Plugin::signature` is changed, and it
requires plugin authors to change their code for new signatures.

Fortunally it should be easy to change, for rust based plugin, we just
need to make a global replace from word `Signature` to word
`PluginSignature` in their plugin project.

Our content of plugin-path is really large, if one plugin have many
examples, it'd results to larger body of $nu.plugin-path, which is not
really scale. A solution would be save register information in other
binary formats rather than `json`. But I think it'd be another story.

report which datetime couldn't be converted (#7980)
# Description

This PR will help report a bad date that can't be converted where the
error message says `* Unable to parse datetime`. This is helpful when
you're converting a big table and it fails somewhere that you really

there should be something there.

Name threads (#7879)
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.

add decimal to SyntaxShape (#7852)
# Description

This adds the `SyntaxShape::Decimal` so you can create custom commands
with `decimal` types such as:
```shell
def cmd [x:decimal] { echo $x }
```

/cc @kurokirasama

Internally this is a little messy since we have `Type::Float` and
`SyntaxShape::Decimal`. I originally named it `float` and
`SyntaxShape::Float` but since we have `into decimal` and `1.1 |
describe` reports `decimal`, I decided to change the SyntaxShape.

LazyRecord (#7619)
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)

Fix typos and use more idiomatic assertions (#7755)
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

Support redirect err and out to different streams (#7685)
# Description

Closes: #7364 

# User-Facing Changes

Given the following shell script:
```bash
x=$(printf '=%.0s' {1..100})
echo $x
echo $x 1>&2
```

It supports the following command:
```
bash test.sh out> out.txt err> err.txt
```

Then both `out.txt` and `err.txt` will contain `=`(100 times)

## About the change

The core idea is that when doing lite-parsing, introduce a new variant
`LiteElement::SeparateRedirection` if we meet two Redirection
token(which is generated by `lex` function),
During converting from lite block to block,
`LiteElement::SeparateRedirection` will be converted to
`PipelineElement::SeparateRedirection`.

Then in the block eval process, if we get
`PipelineElement::SeparateRedirection`, we invoke `save` command with
`--stderr` arguments to acthive our behavior.



## What happened internally?
Take the following command as example:
```
^ls out> out.txt err> err.txt
```

lex parsing result(`Tokens`) are not changed, but `LiteBlock` and
`Block` is changed after this pr.

### LiteBlock before
```rust
LiteBlock {
    block: [
        LitePipeline { commands: [
            Command(None, LiteCommand { comments: [], parts: [Span { start: 39041, end: 39044 }] }),
            // actually the span of first Redirection is wrong too..
            Redirection(Span { start: 39058, end: 39062 }, Stdout, LiteCommand { comments: [], parts: [Span { start: 39050, end: 39057 }] }),
            Redirection(Span { start: 39058, end: 39062 }, Stderr, LiteCommand { comments: [], parts: [Span { start: 39063, end: 39070 }] })
        ]
    }]
}
```
### LiteBlock after
```rust
LiteBlock {
    block: [
        LitePipeline { commands: [
            Command(
                None, 
                LiteCommand { comments: [], parts: [Span { start: 38525, end: 38528 }] }),
                // new one! two Redirection merged into one SeparateRedirection.
                SeparateRedirection { 
                    out: (Span { start: 38529, end: 38533 }, LiteCommand { comments: [], parts: [Span { start: 38534, end: 38541 }] }),
                    err: (Span { start: 38542, end: 38546 }, LiteCommand { comments: [], parts: [Span { start: 38547, end: 38554 }] })
                }
        ]
    }]
}
```

Progress bar Implementation (#7661)
# 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

Fix line-end trimming in subexpression (#7543)
# Description

Currently the implementation is different for Windows and Unix.

Thus certain operations will fail if the platform foreign line ending is
used:

example failing under windows

```
git show (git merge-base main HEAD)
```

Temporary cheat is to strip all `\r` and `\n` from the end. Proper
solution should trim them as correct patterns.

Also needed: test of behavior with both platform newline and
platform-foreign line endings

move BufferedReader out of nu-command (#7697)
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".

Limit recursion to avoid stack overflow (#7657)
Add recursion limit to `def` and `block`.
Summary of this PR , it will detect if `def` call itself or not .
Then execute by using `stack` which I think best choice to use with this
design and core as it is available in all crates and mutable and
calculate the recursion limit on calling `def`.
Set 50 as recursion limit on `Config`.
Add some tests too .

Further cleanup of Span::test_data usage + span fixes (#7595)
# 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

Add LRU regex cache (#7587)
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.

Standardise the use of ShellError::UnsupportedInput and ShellError::TypeMismatch and add spans to every instance of the former (#7217)
# 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.

Make config.filesize_format/config.filesize_metric conflict resolution consistent (#7410)
# 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.

Fix cell path when getting columns of non-records (#7508)
A follow-up to #7497. That change made it so that `get foo` would
eliminate non-record rows; I think that was an unintentional and
undesirable side-effect.

Before #7497:
```bash
〉[$nothing, { item: "foo" }] | get item
╭───┬─────╮
│ 0 │     │
│ 1 │ foo │
╰───┴─────╯
```
After #7497:
```bash
〉[$nothing, {item: "foo"}] | get item
╭───┬─────╮
│ 0 │ foo │
╰───┴─────╯
```

After this PR:
```bash
〉[$nothing, { item: "foo" }] | get item

color_config now accepts closures as color values (#7141)
# 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
```
Example output with this in effect:

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.

Use nu-path correctly in nu! test macro to make dev-dependency transitive (#7488)
## 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.

Add helper method to check whether ctrl+c was pressed, adopt it (#7482)
I've been working on streaming and pipeline interruption lately. It was
bothering me that checking ctrl+c (something we want to do often) always
requires a bunch of boilerplate like:
```rust
use std::sync::atomic::Ordering;

if let Some(ctrlc) = &engine_state.ctrlc {
     if ctrlc.load(Ordering::SeqCst) {
          ...
```
I added a helper method to cut that down to:

```rust
if nu_utils::ctrl_c::was_pressed(&engine_state.ctrlc) {
    ...

Revert "Pipeline operators: && and ||" (#7452)
Reverts nushell/nushell#7448

Some surprising behavior in how we do this. For example:

```
〉if (true || false) { print "yes!" } else { print "no!" }
no!
〉if (true or false) { print "yes!" } else { print "no!" }
yes!
```

This means for folks who are using the old `||`, they possibly get the
wrong answer once they upgrade. I don't think we can ship with that as
it will catch too many people by surprise and just make it easier to
write buggy code.

Pipeline operators: && and || (#7448)
# Description

We got some feedback from folks used to other shells that `try/catch`
isn't quite as convenient as things like `||`. This PR adds `&&` as a
synonym for `;` and `||` as equivalent to what `try/catch` would do.

# User-Facing Changes

Adds `&&` and `||` pipeline operators.

Move 'where' to parser keywords; Add 'filter' command (#7365)
# Description

This PR moves the `where` command to a parser keyword. While it still
uses the shape-directed parsing dictated by the signature, we're free to
change the parsing code now to a custom one once we remove the syntax
shapes.

As a side effect, the `where -b` flag was removed and its functionality
has moved to the new `filter` command.

Just FYI, other commands that take row conditions:
- `take until`
- `take while`
- `skip until`
- `skip while`
- `any`
- `all`

We can either move these to the parser as well or make them accept a
closure instead of row condition.

# User-Facing Changes

New `filter` command which replaces `where -b` functionality.

$env.config now always holds a record with only valid values (#7309)
# 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

Reduced LOC by replacing several instances of Value::Int {}, Value::Float{}, Value::Bool {}, and Value::String {} with Value::int(), Value::float(), Value::boolean() and Value::string() (#7412)
# Description

While perusing Value.rs, I noticed the `Value::int()`, `Value::float()`,
`Value::boolean()` and `Value::string()` constructors, which seem
designed to make it easier to construct various Values, but which aren't
used often at all in the codebase. So, using a few find-replaces
regexes, I increased their usage. This reduces overall LOC because
structures like this:
```
Value::Int {
  val: a,
  span: head
}
```
are changed into
```
Value::int(a, head)
```
and are respected as such by the project's formatter.
There are little readability concerns because the second argument to all
of these is `span`, and it's almost always extremely obvious which is
the span at every callsite.

Add OneOf shape to fix else (#7385)
# Description

fixes #7384 

This is a stop-gap fix until we remove type-directed parsing. With this,
you can create a `OneOf` shape that can be one of a list of syntax
shapes. This gives you a little more control than you get with `Any`,
allowing you to add `Block` without breaking other parsing rules.

# User-Facing Changes

`else` block will no longer capture variables as it will now use a block
instead of a closure.

Improve empty pipelines (#7383)

This fix changes pipelines to allow them to actually be empty. Mapping

Allow $env and mutable records to be mutated by = (closes #7110) (#7318)
# Description

Closes #7110. ~~Note that unlike "real" `mut` vars, $env can be deeply
mutated via stuff like `$env.PYTHON_IO_ENCODING = utf8` or
`$env.config.history.max_size = 2000`. So, it's a slightly awkward
special case, arguably justifiable because of what $env represents (the
environment variables of your system, which is essentially "outside"
normal Nushell regulations).~~
EDIT: Now allows all `mut` vars to be deeply mutated using `=`, on
request.

Protocol: debug_assert!() Span to reflect a valid slice (#6806)
Also enforce this by #[non_exhaustive] span such that going forward we
cannot, in debug builds (1), construct invalid spans.

The motivation for this stems from #6431 where I've seen crashes due to
invalid slice indexing.

My hope is this will mitigate such senarios

Handle ctrl-c in RawStream iterator (#7314)
Fixes #7246 and #1898.

Darren noticed that `open /dev/random` could not be interrupted by
`ctrl+c`. Thankfully the solution was very simple; it looks like we just
forgot to check `ctrlc` in the `impl Iterator for RawStream`!

To reproduce this, just run `open /dev/random` and then cancel it with
`ctrl+c`.

Rename $env.config.explore_config to $env.config.explore (for consistency with $env.config.ls, $env.config.table etc.) (#7317)
# Description

* `$env.config.explore_config` renamed to `$env.config.explore`. This
follows the principle that config subrecords relating to single commands
(as this relates to `explore`) should be exactly named after the command
(see `ls`, `rm`, `table` etc.)
* In `into_config()`, moved the match arm relating to
`$env.config.explore` out of the "legacy options" section (which is
slated for removal in a later version).

[MVP][WIP] less like pager (#6984)
Run it as `explore`.

#### example

```nu
ls | explore
```

Configuration points in `config.nu` file.
```
  # A 'explore' utility config
   explore_config: {
     highlight: { bg: 'yellow', fg: 'black' }
     status_bar: { bg: '#C4C9C6', fg: '#1D1F21' }
     command_bar: { fg: '#C4C9C6' }
     split_line: '#404040'
     cursor: true
     # selected_column: 'blue'
     # selected_row: { fg: 'yellow', bg: '#C1C2A3' }
     # selected_cell: { fg: 'white', bg: '#777777' }
     # line_shift: false,
     # line_index: false,
     # line_head_top: false,
     # line_head_bottom: false,
   }
```

You can start without a pipeline and type `explore` and it'll give you a
few tips.

If you type `:help` you an see the help screen with some information on
what tui keybindings are available.

From the `:help` screen you can now hit `i` and that puts you in
`cursor` aka `inspection` mode and you can move the cursor left right up
down and it you put it on an area such as `[table 5 rows]` and hit the
enter key, you'll see something like this, which shows all the `:`
commands. If you hit `esc` it will take you to the previous screen.

If you then type `:try` you'll get this type of window where you can
type in the top portion and see results in the bottom.

The `:nu` command is interesting because you can type pipelines like
`:nu ls | sort-by type size` or another pipeline of your choosing such
as `:nu sys` and that will show the table that looks like this, which
we're calling "table mode".

![image](https://user-images.githubusercontent.com/343840/205090809-e686ff0f-6d0b-4347-8ed0-8c59adfbd741.png)

If you hit the `t` key it will now transpose the view to look like this.

![image](https://user-images.githubusercontent.com/343840/205090948-a834d7f2-1713-4dfe-92fe-5432f287df3d.png)

In table mode or transposed table mode you can use the `i` key to
inspect any collapsed field like `{record 8 fields}`, `[table 16 rows]`,
`[list x]`, etc.

One of the original benefits was that when you're in a view that has a
lot of columns, `explore` gives you the ability to scroll left, right,
up, and down.

`explore` is also smart enough to know when you're in table mode versus
preview mode. If you do `open Cargo.toml | explore` you get this.

If you type `open --raw Cargo.toml | explore` you get this where you can
scroll left, right, up, down. This is called preview mode.

![image](https://user-images.githubusercontent.com/343840/205091990-69455191-ab78-4fea-a961-feafafc16d70.png)

When you're in table mode, you can also type `:preview`. So, with `open
--raw Cargo.toml | explore`, if you type `:preview`, it will look like
this.

Add logical xor operator (#7242)
We already have the binary `bit-xor` and the shortcircuiting logical
`or`(`||`) and `and`(`&&`).
This introduces `xor` as a compact form for both brevity and clarity.
You can express the operation through `not`/`and`/`or` with a slight
risk of introducing bugs through typos.

Operator precedence

`and` > `xor` > `or`

Added logic and precedence tests.

It also converts dates into record but I couldn't get the test harness
to accept an example.

Thanks to @WindSoilder for writing the "hard" parts of this. :)

New commands: break, continue, return, and loop (#7230)
# Description

This adds `break`, `continue`, `return`, and `loop`.

* `break` - breaks out a loop
* `continue` - continues a loop at the next iteration
* `return` - early return from a function call
* `loop` - loop forever (until the loop hits a break)

Examples:
```
for i in 1..10 {
    if $i == 5 {
       continue
    } 
    print $i
}
```

```
for i in 1..10 {
    if $i == 5 {
        break
    } 
    print $i
}
```

```
def foo [x] {
    if true {
        return 2
    }
    $x
}
foo 100
```

```
loop { print "hello, forever" }
```

```
[1, 2, 3, 4, 5] | each {|x| 
    if $x > 3 { break }
    $x
}
```

Make external command substitution works friendly(like fish shell, trailing ending newlines) (#7156)
# Description

As title, when execute external sub command, auto-trimming end
new-lines, like how fish shell does.

And if the command is executed directly like: `cat tmp`, the result
won't change.

Fixes: #6816
Fixes: #3980


Note that although nushell works correctly by directly replace output of
external command to variable(or other places like string interpolation),
it's not friendly to user, and users almost want to use `str trim` to
trim trailing newline, I think that's why fish shell do this
automatically.

If the pr is ok, as a result, no more `str trim -r` is required when
user is writing scripts which using external commands.

Stdout/Stderr redirection (#7185)

Make json require string and pass around metadata (#7010)
* Make json require string and pass around metadata

The json deserializer was accepting any inputs by coercing non-strings
into strings. As an example, if the input was `[1, 2]` the coercion
would turn into `[12]` and deserialize as a list containing number
twelve instead of a list of two numbers, one and two. This could lead
to silent data corruption.

Aside from that pipeline metadata wasn't passed aroud.

This commit fixes the type issue by adding a strict conversion
function that errors if the input type is not a string or external
stream. It then uses this function instead of the original
`collect_string()`. In addition, this function returns the pipeline
metadata so it can be passed along.

* Make other formats require string

The problem with json coercing non-string types to string was present in
all other text formats. This reuses the `collect_string_strict` function
to fix them.

* `IntoPipelineData` cleanup

The method `into_pipeline_data_with_metadata` can now be conveniently
used.
