add helper switch to move cursor to end of buffer (#10354)
# Description

This PR adds a helper flag named `--cursor-end`/`-e` that allows you to
set the cursor to the end of the buffer. Before this, you'd have to do
something like `--cursor 100` where you're guessing that 100 would be
longer than the buffer and just put it at the end.

Deref &String arguments to &str where appropriate (#10321)
# Description
This generally makes for nicer APIs, as you are not forced to use an
existing allocation covering the full `String`.

Some exceptions remain where the underlying type requirements favor it.

Make cursor_shape optional (#10289)
# Description
There are several cursor shape related issues #7151 #9243 #7271 #8452
#10169, you can't disable the cursor shape feature even if you comment
out the entire `cursor_shape` block in the config.nu, and even worse,
when nushell exits with an error, the cursor shape can't be restored,
that is annoying.

This PR provides an opportunity to disable setting the cursor shape.

# User-Facing Changes
If you use the default config.nu, nothing changes, but if you comment
out `cursor_shape` block or set them to `inherit`, related cursor shape
will not be set.

signpost 'input list --types [key]' from 'keybindings list' (#10287)
Supercedes https://github.com/nushell/nushell/pull/10196

# Description

After reading
https://github.com/nushell/nushell/pull/10196#issuecomment-1703986359 I
added a signpost from `keybindings listen` to `input listen`

When I initially tried `input listen` it always immediately returned
with:
```
╭───────┬────────╮
│ type  │ focus  │
│ event │ gained │
╰───────┴────────╯
```

I added an example to `input listen --help` to suggest only listening to
key events

Initially I also included a `result` but it prints as:

```
  ╭───────────┬───────────────╮
  │ type      │ key           │
  │ key_type  │ char          │
  │ code      │ c             │
  │ modifiers │ [list 1 item] │
  ╰───────────┴───────────────╯
```

rather than:

```
╭───────────┬───────────────────────────────╮
│ type      │ key                           │
│ key_type  │ char                          │
│ code      │ c                             │
│           │ ╭───┬───────────────────────╮ │
│ modifiers │ │ 0 │ keymodifiers(control) │ │
│           │ ╰───┴───────────────────────╯ │
╰───────────┴───────────────────────────────╯
```
so I removed it.

# User-Facing Changes

<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

* Example describing how to use `input list --types [key]` to listen for
keybindings.
* Signpost pointing at `use std input; input list --types [key]` from
`keybindings list`.

## After merging

It is probably worth:

a) signposting to the keybindings section of the book from both of these
subcommands (like I did in
https://github.com/nushell/nushell/pull/10193),
b) giving an example in the book of how to take the output from `input
listen --types [key]` and format it for including in `config nu`
c) there are not currently any examples in
crates/nu-utils/src/sample_config/default_config.nu for keybindings with
multiple modifiers. Should I add alt+backspace-in-macos-vscode as an
example (gets translated to `{ modifier: control_alt keycode: char_h }`
for historical reasons)?

support tab completion cycling (#10199)
should close https://github.com/nushell/nushell/issues/7202

# Description
i have been annoyed enough by this missing feature, so let's add that to
Nushell without requiring any user configuration 😏

# User-Facing Changes
this PR should allow tab completion cycling everytime, without requiring
the user to use the default config files or add the following
keybindings to their config
```nushell
    {
        name: completion_menu
        modifier: none
        keycode: tab
        mode: [emacs vi_normal vi_insert]
        event: {
            until: [
                { send: menu name: completion_menu }
                { send: menunext }
                { edit: complete }
            ]
        }
    }
```

### 🧪 try it out
from the root of the repo, one can try `<tab>` in each of the following
cases:
- `cargo run -- -n` to load Nushell without any config
- `cargo run -- --config
crates/nu-utils/src/sample_config/default_config.nu --env-config
crates/nu-utils/src/sample_config/default_env.nu` to load the default
configuration
- `cargo run` to load the user configuration

## before
- `<tab>`, `ls <tab>` and `str <tab>` only work with the second `cargo
run`, i.e. when loading the default config files

## after
- `<tab>` should cycle through the available commands
- `ls <tab>` should cycle through the available files and directories
- `str <tab>` should cycle the subcommands of `str`

in all three cases

Move Value to helpers, separate span call (#10121)
# Description

As part of the refactor to split spans off of Value, this moves to using
helper functions to create values, and using `.span()` instead of
matching span out of Value directly.

Hoping to get a few more helping hands to finish this, as there are a
lot of commands to update :)

Move eval_hook to nu-cmd-base (#10146)
I moved hook to *nu_cmd_base* instead of *nu_cli* because it will enable
other developers to continue to use hook even if they decide to write
their on cli or NOT depend on nu-cli

Then they will still have the hook functionality because they can
include nu-cmd-base

name hooks internally (#10127)
# Description

This PR names the hooks as they're executing so that you can see them
with debug statements. So, at the beginning of `eval_hook()` you could
put a dbg! or eprintln! to see what hook was executing. It also shows up
in View files.

### Before - notice item 14 and 25

![image](https://github.com/nushell/nushell/assets/343840/22c19bbe-6bac-4132-9579-863922d91f22)

### After - The hooks are now named (14 & 25)

![image](https://github.com/nushell/nushell/assets/343840/a08abd11-4f03-4f09-bbac-e4b5180df078)


Curiosity, on my mac, the display_output hook fires 3 times before
anything else. Also, curious is that the value if the display_output, is
not what I have in my config but what is in the default_config. So,
there may be a bug or some shenanigans going on somewhere with hooks.

Spanned Value step 1: span all value cases (#10042)
# Description

This doesn't really do much that the user could see, but it helps get us
ready to do the steps of the refactor to split the span off of Value, so
that values can be spanless. This allows us to have top-level values
that can hold both a Value and a Span, without requiring that all values
have them.

We expect to see significant memory reduction by removing so many
unnecessary spans from values. For example, a table of 100,000 rows and
5 columns would have a savings of ~8megs in just spans that are almost
always duplicated.

Create Record type (#10103)
# Description
This PR creates a new `Record` type to reduce duplicate code and
possibly bugs as well. (This is an edited version of #9648.)
- `Record` implements `FromIterator` and `IntoIterator` and so can be
iterated over or collected into. For example, this helps with
conversions to and from (hash)maps. (Also, no more
`cols.iter().zip(vals)`!)
- `Record` has a `push(col, val)` function to help insure that the
number of columns is equal to the number of values. I caught a few
potential bugs thanks to this (e.g. in the `ls` command).
- Finally, this PR also adds a `record!` macro that helps simplify
record creation. It is used like so:
   ```rust
   record! {
       "key1" => some_value,
       "key2" => Value::string("text", span),
       "key3" => Value::int(optional_int.unwrap_or(0), span),
       "key4" => Value::bool(config.setting, span),
   }
   ```
Since macros hinder formatting, etc., the right hand side values should
be relatively short and sweet like the examples above.

Where possible, prefer `record!` or `.collect()` on an iterator instead
of multiple `Record::push`s, since the first two automatically set the
record capacity and do less work overall.

# User-Facing Changes
Besides the changes in `nu-protocol` the only other breaking changes are
to `nu-table::{ExpandedTable::build_map, JustTable::kv_table}`.

https://github.com/nushell/nushell/pull/9773 introduced constants to
modules and allowed to export them, but only within one level. This PR:
* allows recursive exporting of constants from all submodules
* fixes submodule imports in a list import pattern
* makes sure exported constants are actual constants

Should unblock https://github.com/nushell/nushell/pull/9678

### Example:
```nushell
module spam {
    export module eggs {
        export module bacon {
            export const viking = 'eats'
        }
    }
}

use spam 
print $spam.eggs.bacon.viking  # prints 'eats'

use spam [eggs]
print $eggs.bacon.viking  # prints 'eats'

use spam eggs bacon viking
print $viking  # prints 'eats'
```

### Limitation 1:

Considering the above `spam` module, attempting to get `eggs bacon` from
`spam` module doesn't work directly:
```nushell
use spam [ eggs bacon ]  # attempts to load `eggs`, then `bacon`
use spam [ "eggs bacon" ]  # obviously wrong name for a constant, but doesn't work also for commands
```

Workaround (for example):
```nushell
use spam eggs
use eggs [ bacon ]

print $bacon.viking  # prints 'eats'
```

I'm thinking I'll just leave it in, as you can easily work around this.
It is also a limitation of the import pattern in general, not just
constants.

### Limitation 2:

`overlay use` successfully imports the constants, but `overlay hide`
does not hide them, even though it seems to hide normal variables
successfully. This needs more investigation.

Rename main to script name when running scripts (#9948)
# Description

This PR does three related changes:

* Keeps the originally declared name in help outputs.
* Updates the name of the commands called `main` in the user script to
the name of the script.
* Fixes the source of signature information in multiple places. This
allows scripts to have more complete help output.

Combined, the above allow the user to see the script name in the help
output of scripts, like so:


![image](https://github.com/nushell/nushell/assets/547158/741d192c-0a39-45a7-8f36-3a0dc8eeae2b)

NOTE: You still declare and call the definition `main`, so from inside
the script `main` is still the correct name. But multiple folks agreed
that seeing `main` in the script help was confusing, so this PR changes
that.

# User-Facing Changes

One potential minor breaking change is that module renames will be shown
as their originally defined name rather than the renamed name. I believe
this to be a better default.

add keybinding for search-history (#9930)
# Description

This PR adds a keybinding in the rust code for `search-history` aka
reverse-search as `ctrl+q` so it does not overwrite `history-search`
with `ctrl+r` as it does now.

This PR supercedes #9862. Thanks to @SUPERCILEX for bringing this to our

Fix default prompt indicators (#9914)
related to
- https://github.com/nushell/nushell/pull/9907

# Description
https://github.com/nushell/nushell/pull/9907 removed the front space
from all `PROMPT_INDICATOR`s but this is not what the default behaviour
of Nushell is, i.e. in `nu --no-config-file`.

this PR
- removes the space that is prepended by Nushell before the prompt
indicator to match the `default_env.nu`
- swaps INSERT and NORMAL in the Rust code to match the `:` and `>`
respectively in `default_env.nu`

## 🔍 try the changes
> **Warning**
> i had to comment out in my config all the `$env.PROMPT_INDICATOR... =
...` to avoid these variables to propagate to `cargo run -- -n`

in either `cargo run -- -n` or `cargo run -- --config
crates/nu-utils/src/sample_config/default_config.nu --env-config
crates/nu-utils/src/sample_config/default_env.nu`,
- see `/path/to/nushell>` as the prompt with the default `emacs` edit
mode
- run `$env.config.edit_mode = vi`
- see `/path/to/nushell:` as the INSERT prompt in Vi mode
- press Escape to go into NORMAL mode
- see `/path/to/nushell>` as the NORMAL prompt in Vi mode
- press I to go back into INSERT mode
- see `/path/to/nushell:` as the INSERT prompt in Vi mode

# User-Facing Changes
the prompts in `nu --no-config-file` and `nu --config default_config.nu
--env-config default_env.nu` should be the same 😌

Replace &Span with Span since Span is Copy (#9770)
# Description
`Span` is `Copy`, so we probably should not be passing references of
`Span` around. This PR replaces all instances of `&Span` with `Span`,
copying spans where necessary.

# User-Facing Changes
This alters some public functions to take `Span` instead of `&Span` as
input. Namely, `EngineState::get_span_contents`,
`nu_protocol::extract_value`, a bunch of the math commands, and
`Gstat::gstat`.

allow print to take data as input again (#9823)
related to
https://discord.com/channels/601130461678272522/601130461678272524/1134079115134251129

# Description
before 0.83.0, `print` used to allow piping data into it, e.g.
```nushell
"foo" | print
```
instead of 
```nushell
print "foo"
```

this PR enables the `any -> nothing` input / output type to allow this
again.

i've double checked and `print` is essentially the following snippet
```rust
        if !args.is_empty() {
            for arg in args {
                arg.into_pipeline_data()
                    .print(engine_state, stack, no_newline, to_stderr)?;
            }
        } else if !input.is_nothing() {
            input.print(engine_state, stack, no_newline, to_stderr)?;
        }
```
1. the first part is for `print a b c`
2. the second part is for `"foo" | print`

# User-Facing Changes
```nushell
"foo" | print
```
works again

Add functions for each Value case (#9736)
# Description
This PR ensures functions exist to extract and create each and every
`Value` case. It also renames `Value::boolean` to `Value::bool` to match
`Value::test_bool`, `Value::as_bool`, and `Value::Bool`. Similarly,
`Value::as_integer` was renamed to `Value::as_int` to be consistent with
`Value::int`, `Value::test_int`, and `Value::Int`. These two renames can
be undone if necessary.

# User-Facing Changes
No user facing changes, but two public functions were renamed which may
affect downstream dependents.

add more input_output_types found from breaking scripts (#9683)
# Description

This PR fixes some problems I found in scripts by adding some additional
input_output_types.

Here's a list of nushell scripts that it fixed. Look for `# broke here:`
below.

This PR fixes 3, 4, 6, 7 by adding additional input_output_types. 1 was
fixed by changing the script. 2. just doesn't work anymore because mkdir
return type has changed. 5, is a problem with the script, the datatype
for `...rest` needed to be removed.

```nushell
# 1.
def terminal-size [] {
    let sz = (input (ansi size) --bytes-until 'R')
    # $sz should look like this
    # Length: 9 (0x9) bytes | printable whitespace ascii_other non_ascii
    # 00000000:   1b 5b 33 38  3b 31 35 30  52                         •[38;150R
    let sz_len = ($sz | bytes length)

    # let's skip the esc[ and R
    let r = ($sz | bytes at 2..($sz_len - 2) | into string)

    # $r should look like 38;150
    # broke here: because $r needed to be a string for split row
    let size = ($r | split row ';')

    # output in record syntax
    {
        rows: ($size | get 0)
        columns: ($size | get 1)
    }
}

# 2.
# make and cd to a folder
def-env mkcd [name: path] {
    # broke here: but apparently doesn't work anymore
    # It looks like  mkdir returns nothing where it used to return a value
    cd (mkdir $name -v | first) 
}

# 3.

  (seq date -r --days 7 |

Remove broken compile-time overload system (#9677)
# Description

This PR removes the compile-time overload system. Unfortunately, this
system never worked correctly because in a gradual type system where
types can be `Any`, you don't have enough information to correctly
resolve function calls with overloads. These resolutions must be done at
runtime, if they're supported.

That said, there's a bit of work that needs to go into resolving
input/output types (here overloads do not execute separate commands, but
the same command and each overload explains how each output type
corresponds to input types).

This PR also removes the type scope, which would give incorrect answers
in cases where multiple subexpressions were used in a pipeline.

# User-Facing Changes

Finishes removing compile-time overloads. These were only used in a few
places in the code base, but it's possible it may impact user code. I'll
mark this as breaking change so we can review.

Use is-terminal crate for now (#9670)
# Description
Until we bump our minimal Rust version to `1.70.0` we can't use
`std::io::IsTerminal`. The crate `is-terminal` (depending on `rustix` or
`windows-sys`) can provide the same.
Get's rid of the dependency on the outdated `atty` crate.
We already transitively depend on it (e.g. through `miette`)

As soon as we reach the new Rust version we can supersede this with

# Description
Fixes #9268, the issue was due to the fact that when `history_isolation`
was set to true the engine_state's `session_id` wasn't updated.

This PR mainly refactors the code that updates the line_editor's history
information into one function `update_line_editor_history` and also
updates the engine_state's `session_id` when `history_isolation` is set
to `true` by calling the function `store_history_id_in_engine`.

I tried to extract the block that was updating the line_editor's
`session_id` to make it easier to add a test.
The test checks that after a call to the function
`update_line_editor_history`, the `engine_state` and the returned
`line_editor` do have the same `session_id`.

Exclude deprecated commands from completions (#9612)
# Description
We previously simply searched all commands in the working set. As our
deprecated/removed subcommands are documented by stub commands that
don't do anything apart from providing a message, they were still
included.
With this change we check the `Signature.category` to not be
`Category::Deprecated`.

## Note on performance
Making this change will exercise `Command.signature()` more
frequently! As the rust-implemented commands include their builders here
this probably will cause a number of extra allocations. There is
actually no valid reason why the commands should construct a new
`Signature` for each call to `Command.signature()`.
This will introduce some overhead to generate the completions for
commands.

revert: move to ahash (#9464)
This PR reverts https://github.com/nushell/nushell/pull/9391

We try not to revert PRs like this, though after discussion with the
Nushell team, we decided to revert this one.

The main reason is that Nushell, as a codebase, isn't ready for these
kinds of optimisations. It's in the part of the development cycle where
our main focus should be on improving the algorithms inside of Nushell
itself. Once we have matured our algorithms, then we can look for
opportunities to switch out technologies we're using for alternate
forms.

Much of Nushell still has lots of opportunities for tuning the codebase,
paying down technical debt, and making the codebase generally cleaner
and more robust. This should be the focus. Performance improvements
should flow out of that work.

Said another, optimisation that isn't part of tuning the codebase is
premature at this stage. We need to focus on doing the hard work of
making the engine, parser, etc better.

Break up interdependencies of command crates (#9429)
# Description
Make sure that our different crates that contain commands can be
compiled in parallel.
This can under certain circumstances accelerate the compilation with
sufficient multithreading available.

## Details
- Move `help` commands from `nu-cmd-lang` back to `nu-command`
- This also makes sense as the commands are implemented in an
ANSI-terminal specific way
- Make `nu-cmd-lang` only a dev dependency for `nu-command`
- Change context creation helpers for `nu-cmd-extra` and
`nu-cmd-dataframe` to have a consistent api used in
`src/main.rs`:`get_engine_state()`
- `nu-command` now indepedent from `nu-cmd-extra` and `nu-cmd-dataframe`
that are now dependencies of `nu` directly. (change to internal
features)
- Fix tests that previously used `nu-command::create_default_context()`
with replacement functions

## From scratch compilation times:

just debug (dev) build and default features
```
cargo clean --profile dev && cargo build --timings
```

# User-Facing Changes
None direct, only change to compilation on multithreaded jobs expected.

# Tests + Formatting
Tests that previously chose to use `nu-command` for their scope will
still use `nu-cmd-lang` + `nu-command` (command list in the granularity
at the time)

Enable history entry exclusion with leading space (#9371)
# Description
Makes use of the feature introduced by nushell/reedline#566

If we consider this to be problematic we can decide to add a config
point for this behavior, but at first I was a bit hesistant expanding
the config in this area.


# User-Facing Changes
Follows precedent found in bash/zsh/fish to exclude lines starting with
a space from the history.
Like in fish you can still recall the last entry once but it will not be
stored and will be forgotten after the next submitted entry.

see https://github.com/nushell/nushell/issues/9390
using `ahash` instead of the default hasher. this will not affect
compile time as we where already building `ahash`.

disable bracketed paste during evaluation (#9399)
# Description
Fixes: #9218

When user execute some commands involve user input, currently if we
enable `bracketed_paste`, it will results strange behavior (Pasting `0~`
and `1~` around texts, e.g: `aaa` -> `0~aaa1~`) And this is why `gpg`
with paste failed.

Sorry that it's hard to make relative testing...

Avoid blocking when o+e> redirects too much stderr message (#8784)
# Description

Fixes: #8565

Here is another pr #7240 tried to address the issue, but it works in a
wrong way.

After this change `o+e>` won't redirect all stdout message then stderr
message and it works more like how bash does.

# User-Facing Changes

For the given python code:
```python
# test.py
import sys

print('aa'*300, flush=True)
print('bb'*999999, file=sys.stderr, flush=True)
print('cc'*300, flush=True)
```

Running `python test.py out+err> a.txt` shoudn't hang nushell, and
`a.txt` keeps output in the same order

## About the change
The core idea is that when doing lite-parsing, introduce a new variant
`LiteElement::SameTargetRedirection` if we meet `out+err>` redirection
token(which is generated by lex function),

During converting from lite block to block,
LiteElement::SameTargetRedirection will be converted to
PipelineElement::SameTargetRedirection.

Then in the block eval process, if we get
PipelineElement::SameTargetRedirection, we'll invoke `run-external` with
`--redirect-combine` flag, then pipe the result into save command

## What happened internally?

Take the following command as example:
`^ls o+e> log.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 }, StdoutAndStderr, LiteCommand { comments: [], parts: [Span { start: 39050, end: 39057 }] }),
        ]
    }]
}
```
### LiteBlock after
```rust
LiteBlock { 
    block: [
        LitePipeline {
            commands: [
                SameTargetRedirection {
                    cmd: (None, LiteCommand { comments: [], parts: [Span { start: 147945, end: 147948}]}),
                    redirection: (Span { start: 147949, end: 147957 }, LiteCommand { comments: [], parts: [Span { start: 147958, end: 147965 }]})
                }
            ]
        }
    ]
}
```
### Block before
```rust
Pipeline {
    elements: [
        Expression(None, Expression {
            expr: ExternalCall(Expression { expr: String("ls"), span: Span { start: 39042, end: 39044 }, ty: String, custom_completion: None }, [], false),
            span: Span { start: 39041, end: 39044 },
            ty: Any, custom_completion: None 
        }),
        Redirection(Span { start: 39058, end: 39062 }, StdoutAndStderr, Expression { expr: String("out.txt"), span: Span { start: 39050, end: 39057 }, ty: String, custom_completion: None })] }
```
### Block after
```rust
Pipeline {
    elements: [
        SameTargetRedirection { 
            cmd: (None, Expression {
                expr: ExternalCall(Expression { expr: String("ls"), span: Span { start: 147946, end: 147948 }, ty: String, custom_completion: None}, [], false),
                span: Span { start: 147945, end: 147948},
                ty: Any, custom_completion: None
            }),
            redirection: (Span { start: 147949, end: 147957}, Expression {expr: String("log.txt"), span: Span { start: 147958, end: 147965 },ty: String,custom_completion: None}
        }

Parameter defaults to $nu.scope.commands (#9152)
(*third* try at posting this PR, #9104, like #9084, got polluted with
unrelated commits. I'm never going to pull from the github feature
branch again!)

# Description
<!--
Thank you for improving Nushell. Please, check our [contributing
guide](../CONTRIBUTING.md) and talk to the core team before making major
changes.

Description of your pull request goes here. **Provide examples and/or
screenshots** if your changes affect the user experience.

Show parameter defaults in scope command signature, where they're
available for display by help.
per https://github.com/nushell/nushell/issues/8928.

I found unexpected ramifications in one completer (NuHelpCompleter) and
plugins, which both use the flag-formatting routine from builtin help.
For the moment I made the minimum necessary changes to get the mainline
scenario to pass tests and run. But we should circle back on what to do
with plugins and help completer..

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
1. New `parameter_default` column to `signatures` table in
`$nu.scope.commands`
It is populated with whatever parameters can be defaulted: currently
positional args and named flags.
2. Built in help (both `help <command>` and `<command> --help` will
display the defaults
3. Help completer will display defaults for flags, but not for
positionals.

Example:
A custom command with some default parameters:
```
〉cat ~/work/dflts.nu 
# sample function to show defaults in help
export def main [
    arg1: string        # mandatory positional
    arg2:string=abc     # optional positional
    --switch            # no default here
    --named:int         # named flag, no default
    --other:string=def  # flag 
    --hard:record<foo:int bar:string, bas:bool> # default can be compound type
            = {foo:22, bar:"other worlds", bas:false}
] { {arg1: $arg1,
    arg2: $arg2,
    switch: $switch,
    named: $named,
    other: $other,
    hard: $hard, }
}

REFACTOR: move the banner from the rust source to the standard library (#8406)
Related to:
- #8311 
- #8353

# Description
with the new `$nu.startup-time` from #8353 and as mentionned in #8311,
we are now able to fully move the `nushell` banner from the `rust`
source base to the standard library.

this PR
- removes all the `rust` source code for the banner
- rewrites a perfect clone of the banner to `std.nu`, called `std
banner`
- call `std banner` from `default_config.nu`

# User-Facing Changes
see the demo: https://asciinema.org/a/566521

- no config will show the banner (e.g. `cargo run --release --
--no-config-file`)
- a custom config without the `if $env.config.show_banner` block and no
call to `std banner` would never show the banner
- a custom config with the block and `config.show_banner = true` will
show the banner
- a custom config with the block and `config.show_banner = false` will
NOT show the banner

# Tests + Formatting
a new test line has been added to `tests.nu` to check the length of the
`std banner` output.
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

enable history isolation (#9063)
# Description
This PR impacts the nushell sqlite history only.

This is the first PR that enables history isolation in nushell for the
sqlite history. Hopefully, we can continue building on this.

This PR allows "history isolation" which means that other nushell
session's history won't be available in the current session when using
the uparrow/downarrow history navigation. This change only impacts the
uparrow downarrow history navigation.

What remains to be done is making ctrl+r history menu respect this
setting too. Right now, the history menu will still show you all entries
from all sessions.

The history command also shows all history items from all sessions. This
may remain unchanged since you can just filter by history session right
now.

This also fixes a bug where the session id is 0 in the sqlite history
since my April 18th reedline PR.

Closes #9064

support blink cursor, and fix underscore's cursorshape (#8990)
# Description
Close: #8988

Thanks to new crossterm version, nushell can support blink cursor shape.
It can be config with the following value:
1. blink_block
2. blink_line
3. blink_underscore

And original block, line, underscore will be steady. It also fixes wrong
shape of `underscore`.

# User-Facing Changes
Here is a little breaking change, before the change: `line` cursor shape
is blinking line, but after this pr, it will be `steady line`. To make a
blink line, we need to change the value to `blink_line`.

But I think it's ok, because after the change, we have a good naming
convention about the name of shape

Hopefully speedup startup (#8913)
# Description

Trying a few different things to hopefully speedup startup a bit. I'm
seeing some improvement on my box for the profiles I have, but the data
I'm seeing is noisy.

- Remove allocations in a few places where we created vec's but could
use iterators
- Pre-allocate space for blocks based on the lite block
- Removed a few extra clones

Move CLI related commands to nu-cli (#8832)
# Description

Part of the larger cratification effort.

Moves all `reedline` or shell line editor specific commands to `nu-cli`.

## From `nu-cmd-lang`:
- `commandline`
- This shouldn't have moved there. Doesn't directly depend on reedline
but assumes parts in the engine state that are specific to the use of
reedline or a REPL

## From `nu-command`:
- `keybindings` and subcommands
  - `keybindings default`
  - `keybindings list`
  - `keybindings listen`
    - very `reedline` specific
- `history`
  - needs `reedline`
- `history session`

## internal use
Instead of having a separate `create_default_context()` that calls
`nu-command`'s `create_default_context()`, I added a `add_cli_context()`
that updates an `EngineState`


# User-Facing Changes

None

## Build time comparison

`cargo build --timings` from a `cargo clean --profile dev`

### total
main: 64 secs
this: 59 secs

### `nu-command` build time

branch | total| codegen | fraction  
---|---|---|---
main | 14.0s | 6.2s | (44%)
this | 12.5s | 5.5s | (44%)

`nu-cli` depends on `nu-command` at the moment.
Thus it is built during the code-gen phase of `nu-command` (on 16
virtual cores)

# Tests + Formatting

I removed the `test_example()` facilities for now as we had not run any
of the commands in an `Example` test and importing the right context for
those tests seemed more of a hassle than the duplicated
`test_examples()` implementations in `nu-cmd-lang` and `nu-command`

Only add the std lib files once (#8830)
# Description

We were seeing duplicate entries for the std lib files, and this PR
addresses that. Each file should now only be added once.

Note: they are still parsed twice because it's hard to recover the
module from the output of `parse` but a bit of clever hacking in a
future PR might be able to do that.

remove nu_cli crate dependency from nu_std (#8807)
now nu_std only depends on nu_parser, nu_protocol and miette
and removes the nu_cli dependency

this enables developers moving forward to come along and implement their
own CLI's without having to pull in a redundant nu-cli which will not be
needed for them.

I did this by moving report_error into nu_protocol
which nu_std already has a dependency on anyway....

Refactor to support multiple parse errors (#8765)
# Description

This is a pretty heavy refactor of the parser to support multiple parser
errors. It has a few issues we should address before landing:

- [x] In some cases, error quality has gotten worse `1 / "bob"` for
example
- [x] if/else isn't currently parsing correctly
- probably others

This may have error quality degradation as we adjust to the new error
reporting mechanism.

* check - see the errors in the document (currently only one error is
supported)
* hover - get information about the variable or custom command
* complete - get a completion list at the current position

Add pattern matching (#8590)
# Description

This adds `match` and basic pattern matching.

An example:

```
match $x {
  1..10 => { print "Value is between 1 and 10" }
  { foo: $bar } => { print $"Value has a 'foo' field with value ($bar)" }
  [$a, $b] => { print $"Value is a list with two items: ($a) and ($b)" }
  _ => { print "Value is none of the above" }
}
```

Like the recent changes to `if` to allow it to be used as an expression,
`match` can also be used as an expression. This allows you to assign the
result to a variable, eg) `let xyz = match ...`

I've also included a short-hand pattern for matching records, as I think
it might help when doing a lot of record patterns: `{$foo}` which is
equivalent to `{foo: $foo}`.

There are still missing components, so consider this the first step in
full pattern matching support. Currently missing:
* Patterns for strings
* Or-patterns (like the `|` in Rust)
* Patterns for tables (unclear how we want to match a table, so it'll
need some design)
* Patterns for binary values
* And much more

fixes the ability to have multiple modifiers on keybindings (#8579)
# Description

This PR fixes a bug that prevented you from having multiple modifiers on
your keybindings.

TODO:
- The docs need to be fixed too
https://www.nushell.sh/book/line_editor.html#keybindings.
(https://github.com/nushell/nushell.github.io/pull/840)
- I think reedline needs to be changed to show this too since it
provides the list of available modifiers.
(https://github.com/nushell/reedline/pull/559)

Now you can do something like this where `shift` and `alt` are combined
with an underscore.
```
  {
    name: fuzzy_history_fzf
    modifier: shift_alt
    keycode: char_r
    mode: [emacs , vi_normal, vi_insert]
    event: {
blah
}
```
Here's the list of available combinations
```rust
        "control" => KeyModifiers::CONTROL,
        "shift" => KeyModifiers::SHIFT,
        "alt" => KeyModifiers::ALT,
        "none" => KeyModifiers::NONE,
        "shift_alt" | "alt_shift" => KeyModifiers::SHIFT | KeyModifiers::ALT,
        "control_shift" | "shift_control" => KeyModifiers::CONTROL | KeyModifiers::SHIFT,
        "control_alt" | "alt_control" => KeyModifiers::CONTROL | KeyModifiers::ALT,
        "control_alt_shift" | "control_shift_alt" => {
            KeyModifiers::CONTROL | KeyModifiers::ALT | KeyModifiers::SHIFT
        }

Previously when a `executehostcommand` shortcut calls `commandline`, to

Add a `command_not_found` function to `$env.config.hooks`. If this
function outputs a string, then it's included in the `help`.

An example hook on *Arch Linux*, to find packages that contain the
binary, looks like:

```nushell
let-env config = {
  # ...
  hooks: {
    command_not_found: {
      |cmd_name| (
        try {
          let pkgs = (pkgfile --binaries --verbose $cmd_name)
          (
            $"(ansi $env.config.color_config.shape_external)($cmd_name)(ansi reset) " +
            $"may be found in the following packages:\n($pkgs)"
          )
        } catch {
          null
        }
      )
    }
    # ...
```

# User-Facing Changes
- Add a `command_not_found` function to `$env.config.hooks`.

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.

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).

fix: fix commandline when called with no arguments (#8207)
# Description

This fixes the `commandline` command when it's run with no arguments, so
it outputs the command being run. New line characters are included.

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]
 1 │ [{foo: 1} {foo: 2} {}].foo
   ·                    ─┬  ─┬─
   ·                     │   ╰── cannot find column 'foo'
   ·                     ╰── value originates here
   ╰────
〉[{foo: 1} {foo: 2} {}].foo?
╭───┬───╮
│ 0 │ 1 │
│ 1 │ 2 │
│ 2 │   │
╰───┴───╯
〉[{foo: 1} {foo: 2} {}].foo?.2 | describe
nothing

〉[a b c].4? | describe
nothing

〉[{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.

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.

FEATURE: add the startup time to $nu (#8353)
# Description
in https://github.com/nushell/nushell/issues/8311 and the discord
server, the idea of moving the default banner from the `rust` source to
the `nushell` standar library has emerged 😋

however, in order to do this, one need to have access to all the
variables used in the default banner => all of them are accessible
because known constants, except for the startup time of the shell, which
is not anywhere in the shell...

#### this PR adds exactly this, i.e. the new `startup_time` to the `$nu`
variable, which is computed to have the exact same value as the value
shown in the banner.

## the changes
in order to achieve this, i had to
- add `startup_time` as an `i64` to the `EngineState` => this is, to the
best of my knowledge, the easiest way to pass such an information around
down to where the banner startup time is computed and where the `$nu`
variable is evaluated
- add `startup-time` to the `$nu` variable and use the `EngineState`
getter for `startup_time` to show it as a `Value::Duration`
- pass `engine_state` as a `&mut`able argument from `main.rs` down to
`repl.rs` to allow the setter to change the value of `startup_time` =>
without this, the value would not change and would show `-1ns` as the
default value...
- the value of the startup time is computed in `evaluate_repl` in
`repl.rs`, only once at the beginning, and the same value is used in the
default banner 👌

# User-Facing Changes
one can now access to the same time as shown in the default banner with
```bash
$nu.startup-time
```

Document and critically review ShellError variants - Ep. 2 (#8326)
Continuation of #8229 

# 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.

**Everyone:** Feel free to add review comments if you spot inconsistent
use of `ShellError` variants.

- Name fields of `SE::IncorrectValue`
- Merge and name fields on `SE::TypeMismatch`
- Name fields on `SE::UnsupportedOperator`
- Name fields on `AssignmentRequires*` and fix doc
- Name fields on `SE::UnknownOperator`
- Name fields on `SE::MissingParameter`
- Name fields on `SE::DelimiterError`
- Name fields on `SE::IncompatibleParametersSingle`

# User-Facing Changes

(None now, end goal more explicit and consistent error messages)

Make the default prompt play nice with basic fonts (#8080)
# Description
This commit changes the `PROMPT_INDICATOR` and
`PROMPT_INDICATOR_VI_NORMAL` in the default_env and sample_login files.
It also changes its missing fallback in the prompt.rs file.

This has the intention of making the default prompt friendlier when
dealing with basic terminals that may not support displaying a huge
range of the Unicode standard, or users who don't want to get out of
their way to install custom fonts for their terminals. It's also
nicer/more balanced on the eyes, to me, and brings it in line with the
logo of nushell `nu>`.

# User-Facing Changes
New installations of nushell will have > as the default prompt
indicator, and running `config reset` will also change it. This might be
confusing for a few seconds, it could be minor enough that it just feels
slightly off. Anyone who has, for some reason, unset the
PROMPT_INDICATOR variable, or set it to $nothing, will also receive the
`>` treatment.

Users running on basic terminals (like cmd.exe on Windows 10) should no
longer face font issues with the default basic prompt.

# Drawbacks
The Unicode arrow is pretty cool. And it predates many of us. Maybe it's
worth keeping. One argument I could see, and mildly disagree with, is
that it might make users lean towards installing a modern font for their
terminal which will would have good consequences in the future.

pipe binary data to external commands (#8058)
Fixes #7615 

# Description

When calling external commands, we create a table from the pipeline data
to handle external commands expecting paginated input. When a binary
value is made into a table, we convert the vector of bytes representing
the binary bytes into a pretty formatted string. This results in the
pretty formatted string being sent to external commands instead of the
actual binary bytes. By checking whether the stdout of the call is being
redirected, we can decide whether to send the raw binary bytes or the
pretty formatted output when creating a table command.

# User-Facing Changes

When passing binary values to external commands, the external command
will receive the actual bytes instead of the pretty printed string. Use
cases that don't involve piping a binary value into an external command
are unchanged.

files and directory completions now use ascending ordering rather than Levenshtein. #8023 (#8085)
# Description

This change sorts completions for files and directories by the ascending
ordering method, related to issue:
[#8023](https://github.com/nushell/nushell/issues/8023)

Currently the Suggestions are being sorted twice, so it's now following
the convention from `completion/base.rs` to match on the
`self.get_sort_by()` result.

# User-Facing Changes

Previously the suggestions were being sorted by the Levenshtein method:
```
/home/rdevenney/projects/open_source/nushell| cd
src/                wix/                docs/               tests/
assets/             crates/             docker/             images/
target/             benches/            pkg_mgrs/           .git/
.cargo/             .github/
```

Now when you tab for autocompletions, they show up in ascending
alphabetical order as shown below (with hidden files/folders at the
end).
```
/home/rdevenney/projects/open_source/nushell| cd
assets/             benches/            crates/             docker/
docs/               images/             pkg_mgrs/           src/
target/             tests/              wix/                .cargo/
.git/               .github/
```

And when you've already typed a bit of the path:
```
/home/rdevenney/projects/open_source/nushell| cd crates/nu
crates/nu-cli/                   crates/nu-color-config/          crates/nu-command/
crates/nu-engine/                crates/nu-explore/               crates/nu-glob/
crates/nu-json/                  crates/nu-parser/                crates/nu-path/
crates/nu-plugin/                crates/nu-pretty-hex/            crates/nu-protocol/
crates/nu-system/                crates/nu-table/                 crates/nu-term-grid/
crates/nu-test-support/          crates/nu-utils/                 crates/nu_plugin_custom_values/
crates/nu_plugin_example/        crates/nu_plugin_formats/        crates/nu_plugin_gstat/
crates/nu_plugin_inc/            crates/nu_plugin_python/         crates/nu_plugin_query/
```

And another for when there are files and directories present:
```
/home/rdevenney/projects/open_source/nushell/crates/nu-cli/src| nvim                              02/16/2023 08:22:16 AM

Bare word improvements (#8066)
# Description

This does two fixes for bare words:

* It changes completions for paths to wrap a path with backticks if it
starts with a number. This helps bare words that start with numbers be
separate from unit values
* It allows bare words wrapped with backticks to be the name of a
command. Backtick values in command positions are no longer treated as
strings

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.

add some startup performance metrics (#7851)
# 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.

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)

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

                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 }] })
                }

Remove engine_state clones in REPL eval (#7713)
A small but easy optimization for `evaluate_repl()`: clone
`engine_state` 1x instead of 3x.

This reduces time spent in a simple REPL eval (`enter` key pressed with
no command text) by about 10%, as measured in
[Superluminal](https://superluminal.eu/).

clean up some extra logging code in the cli (#7709)
I have been recently going through some info logging in the cli and
noticed that there is too much info being printed to get a handle on
whats going on...

This is an attempt to do some minor logging clean up to print out "less
stuff",
in info logging mode mainly having to do with the prompt...

If someone really want to see what is going on they can very easily add
it
back in without too much trouble.

EDIT: This also changes the semantics of `get`/`select` `-i` somewhat.
I've decided to leave it like this because it works more intuitively
with `default` and `compact`.

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

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.

Fix streaming page missing newline (#7466)
Fixes #7342. `0..1000 | table` before this change:


![image](https://user-images.githubusercontent.com/26268125/207474492-dead4267-d828-4840-8da0-4edfda3e3916.png)

`0..1000 | table` after this change:


![image](https://user-images.githubusercontent.com/26268125/207474583-26633db0-46c5-4c30-8681-654855e7042b.png)

When piping data to `table`, pages were not getting a newline at the
end[^1]. This problem was uncovered and exacerbated by the new
`display_output` hook which implicitly piped _everything_ to `table`.

## The Fix

`PagingTableCreator` now adds a newline to each page instead of relying
on later code to do it.

## Tests

I spent a while trying to write a regression test for this behaviour but
I couldn't get the test to fail before my fix! I think the test
infrastructure does something special with newlines when it's checking
command output. I eventually ran out of steam trying to investigate
that, sorry.

[^1]: unless the pipe to table was the implicit one that's done when
there is no `display_output` hook set. That situation was still working
OK.

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.

Make hook execution stream instead of collecting (#7440)
Closes #7431. In a nutshell:
- `run_hook_block()` in repl.rs was collecting all input into a `Value`
instead of handling streaming input properly
- this was a problem because now we have a default `display_output` hook
that _everything_ gets piped to
- this PR fixes the problem by tweaking `run_hook_block()` to return a
`PipelineData` instead of a `Value`

After this change, individual pages are rendered as they finish. This is
a little easier to see if I tweak `STREAM_PAGE_SIZE` in table.rs to 10:

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.

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" }

A set of fixes for stderr redirect (#7219)
# Description

This is a set of fixes to `err>` to make it work a bit more predictably.

I've also revised the tests, which accidentally tested the wrong thing
for redirection, but should be more correct now.

Limited mutable variables (#7089)
This adds support for (limited) mutable variables. Mutable variables are created with mut much the same way immutable variables are made with let.

Mutable variables allow mutation via the assignment operator (=).

❯ mut x = 100
❯ $x = 200
❯ print $x
200

Mutable variables are limited in that they're only tended to be used in the local code block. Trying to capture a local variable will result in an error:

❯ mut x = 123; {|| $x }
Error: nu::parser::expected_keyword (link)

  × Capture of mutable variable.

The intent of this limitation is to reduce some of the issues with mutable variables in general: namely they make code that's harder to reason about. By reducing the scope that a mutable variable can be used it, we can help create local reasoning about them.

Mutation can occur with fields as well, as in this case:

❯ mut y = {abc: 123}
❯ $y.abc = 456
❯ $y

On a historical note: mutable variables are something that we resisted for quite a long time, leaning as much as we could on the functional style of pipelines and dataflow. That said, we've watched folks struggle to work with reduce as an approximation for patterns that would be trivial to express with local mutation. With that in mind, we're leaning towards the happy path.

Refactor ansi stripping into nu-utils functions (#6966)
Allows use of slightly optimized variants that check if they have to use
the heavier vte parser. Tries to avoid unnnecessary allocations. Initial
performance characteristics proven out in #4378.

Also reduces boilerplate with right-ward drift.
