Avoid uses of Record internals again (#12312)
# Description
Again avoid uses of the `Record` internals, so we are free to change the
data layout

- **Don't use internals of `Record` in `into sqlite`**
- **Don't use internals of `Record` in `to xml`**

Remaining: `rename`

Rename Value::CustomValue to Value::Custom (#12309)
# Description
The second `Value` is redundant and will consume five extra bytes on
each transmission of a custom value to/from a plugin.

# User-Facing Changes
This is a breaking change to the plugin protocol.

The [example in the protocol
reference](https://www.nushell.sh/contributor-book/plugin_protocol_reference.html#value)
becomes

```json
{
  "Custom": {
    "val": {
      "type": "PluginCustomValue",
      "name": "database",
      "data": [36, 190, 127, 40, 12, 3, 46, 83],
      "notify_on_drop": true
    },
    "span": {
      "start": 320,
      "end": 340
    }
  }
}
```

instead of 

```json
{
  "CustomValue": {
    ...
  }
}
```

Add command_prelude module (#12291)
# Description
When implementing a `Command`, one must also import all the types
present in the function signatures for `Command`. This makes it so that
we often import the same set of types in each command implementation
file. E.g., something like this:
```rust
use nu_protocol::ast::Call;
use nu_protocol::engine::{Command, EngineState, Stack};
use nu_protocol::{
    record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, PipelineData,
    ShellError, Signature, Span, Type, Value,
};
```

This PR adds the `nu_engine::command_prelude` module which contains the
necessary and commonly used types to implement a `Command`:
```rust
// command_prelude.rs
pub use crate::CallExt;
pub use nu_protocol::{
    ast::{Call, CellPath},
    engine::{Command, EngineState, Stack},
    record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, IntoSpanned,
    PipelineData, Record, ShellError, Signature, Span, Spanned, SyntaxShape, Type, Value,
};
```

This should reduce the boilerplate needed to implement a command and
also gives us a place to track the breadth of the `Command` API. I tried
to be conservative with what went into the prelude modules, since it
might be hard/annoying to remove items from the prelude in the future.
Let me know if something should be included or excluded.

Always pretty print binary values in table (#12294)
# Description
Binary values passed to `table` may or may not be pretty formatted based
on the output destination. This leads to weird behavior as documented in
#12287. This PR changes `table` to always pretty print binary values.
However, binary values passed to external commands will not be formatted
(this is the existing behavior).

# User-Facing Changes
This is a breaking change. E.g.:
```nushell
0x[8989] | table | cat -
```
used to print raw bytes, but it will now print the pretty formatted
bytes.

# After Submitting
Add to 0.92.0 release notes and update documentation.

Fix return in filter closure eval (#12292)
# Description
Closes https://github.com/nushell/nushell/issues/12257

This was down to the use of `eval_block` instead of
`eval_block_with_early_return`. We may want to reconsider how we
differentiate between this behavior. We currently need to check all the
remaining commands that can invoke a closure block, if they properly
handle `ShellError::Return` as a passing of a `Value`

- **Add test for `return` in `filter` closure**
- **Fix use of `return` in `filter` closure**

# User-Facing Changes
You can now return a value from a `filter` closure

Change default algorithm in detect columns (#12277)
# Description
@fdncred found another histogram based algorithm to detect columns, and
rewrite it in rust: https://github.com/fdncred/guess-width

I have tested it manually, and it works good with `df`, `docker ps`,
`^ps`. This pr is going to use the algorithm in `detect columns`

Fix: #4183

The pitfall of new algorithm:
1. it may not works well if there isn't too much rows of input
2. it may not works well if the length of value is less than the header
to value, e.g:
```
c1 c2 c3 c4 c5
a b c d e
g h i j k
g a a q d
a v c q q | detect columns
```
In this case, users might need to use ~~`--old`~~ `--legacy` to make it
works well.

# User-Facing Changes
User might need to add ~~`--old`~~ `--legacy` to scripts if they find
`detect columns` in their scripts broken.

Initial implementation for uutils uname (#11684)
Hi,
This PR aims at implementing the first iteration for `uname` using
`uutils`. Couple of things:
* Currently my [PR](https://github.com/uutils/coreutils/pull/5921) to
make the required changes is pending in `uutils` repo.
* I guess the number of flags has to be investigated. Still the tests
cover all of them.

ls, rm, cp, open, touch, mkdir: Don't expand tilde if input path is quoted string or a variable. (#12232)
# Description
Fixes:  #11887
Fixes: #11626

This pr unify the tilde expand behavior over several filesystem relative
commands. It follows the same rule with glob expansion:
|  command  |  result |
| ----------- |  ------ |
| ls ~/aaa  | expand tilde
| ls "~/aaa"  | don't expand tilde
| let f = "~/aaa"; ls $f | don't expand tilde, if you want to: use `ls
($f \| path expand)`
| let f: glob = "~/aaa"; ls $f | expand tilde, they don't expand on
`mkdir`, `touch` comamnd.

Actually I'm not sure for 4th item, currently it's expanding is just
because it followes the same rule with glob expansion.

### About the change
It changes `expand_path_with` to accept a new argument called
`expand_tilde`, if it's true, expand it, if not, just keep it as `~`
itself.

# User-Facing Changes
After this change, `ls "~/aaa"` won't expand tilde.

Initial --params implementation (#12249)
# Description
This PR adds a `--params` param to `query db`. This closes #11643.

You can't combine both named and positional parameters, I think this
might be a limitation with rusqlite itself. I tried using named
parameters with indices like `{ ':named': 123, '1': "positional" }` but
that always failed with a rusqlite error. On the flip side, the other
way around works: for something like `VALUES (:named, ?)`, you can treat
both as positional: `-p [hello 123]`.

This PR introduces some very gnarly code repetition in
`prepared_statement_to_nu_list`. I tried, I swear; the compiler wasn't
having any of it, it kept telling me to box my closures and then it said
that the reference lifetimes were incompatible in the match arms. I gave
up and put the mapping code in the match itself, but I'm still not
happy.

Another thing I'm unhappy about: I don't like how you have to put the
`:colon` in named parameters. I think nushell should insert it if it's
[missing](https://www.sqlite.org/lang_expr.html#parameters). But this is
the way [rusqlite
works](https://docs.rs/rusqlite/latest/rusqlite/trait.Params.html#example-named),
so for now, I'll let it be consistent. Just know that it's not really a
blocker, and it isn't a compatibility change to later make `{ colon: 123
}` work, without the quotes and `:`. This would require allocating and
turning our pretty little `&str` into a `String`, though

# User-Facing Changes
Less incentive to leave yourself open to SQL injection with statements
like `query db $"INSERT INTO x VALUES \($unsafe_user_input)"`.
Additionally, the `$""` syntax being annoying with parentheses plays in
our favor, making users even more likely to use ? with `--params`.

Bump base64 from 0.21.7 to 0.22.0 (#12188)

<p><em>Sourced from <a

changelog</a>.</em></p>
<blockquote>
<h1>0.22.0</h1>
<ul>
<li><code>DecodeSliceError::OutputSliceTooSmall</code> is now
conservative rather than precise. That is, the error will only occur if
the decoded output <em>cannot</em> fit, meaning that
<code>Engine::decode_slice</code> can now be used with exactly-sized
output slices. As part of this, <code>Engine::internal_decode</code> now
returns <code>DecodeSliceError</code> instead of
<code>DecodeError</code>, but that is not expected to affect any
external callers.</li>
<li><code>DecodeError::InvalidLength</code> now refers specifically to
the <em>number of valid symbols</em> being invalid (i.e. <code>len % 4
== 1</code>), rather than just the number of input bytes. This avoids
confusing scenarios when based on interpretation you could make a case
for either <code>InvalidLength</code> or <code>InvalidByte</code> being
appropriate.</li>
<li>Decoding is somewhat faster (5-10%)</li>

Get rid of two parallel `Vec`s in `StateDelta` and `EngineState`, that
also duplicated span information. Use a struct with documenting fields.

Also use `Arc<str>` and `Arc<[u8]>` for the allocations as they are
never modified and cloned often (see #12229 for the first improvement).
This also makes the representation more compact as no capacity is
necessary.

# User-Facing Changes

Fix usage of --tabs flag while converting to json (#12115) (#12251)
closes #12115 

# Description
This fix addresses a bug where the --tabs flag couldn't be utilized due
to improper handling of the tab quantity provided by the user.
Previously, the code mistakenly attempted to convert the tab quantity to
a boolean value, leading to a conversion error. The resolution involves
adjusting the condition clauses to properly validate the presence of the
flag's value. Now, the code checks whether the get_flag() function
returns a value or None associated with the --tabs flag. This adjustment
enables the --tabs flag to function correctly, triggering the
appropriate condition and allowing the conversion to proceed as
expected. Similarly, the fix applies to the --indent flag. Additionally,
a default case was added, and the conversion now works properly without
flags. Two tests were added to validate the corrected behavior of these
flags.

# User-Facing Changes
Now the conversion should work properly instead of displaying an error.

Make EngineState clone cheaper with Arc on all of the heavy objects (#12229)
# Description
This makes many of the larger objects in `EngineState` into `Arc`, and
uses `Arc::make_mut` to do clone-on-write if the reference is not
unique. This is generally very cheap, giving us the best of both worlds
- allowing us to mutate without cloning if we have an exclusive
reference, and cloning if we don't.

This started as more of a curiosity for me after remembering that
`Arc::make_mut` exists and can make using `Arc` for mostly immutable
data that sometimes needs to be changed very convenient, and also after
hearing someone complain about memory usage on Discord - this is a
somewhat significant win for that.

The exact objects that were wrapped in `Arc`:

- `files`, `file_contents` - the strings and byte buffers
- `decls` - the whole `Vec`, but mostly to avoid lots of individual
`malloc()` calls on Clone rather than for memory usage
- `blocks` - the blocks themselves, rather than the outer Vec
- `modules` - the modules themselves, rather than the outer Vec
- `env_vars`, `previous_env_vars` - the entire maps
- `config`

The changes required were relatively minimal, but this is a breaking API
change. In particular, blocks are added as Arcs, to allow the parser
cache functionality to work.

With my normal nu config, running on Linux, this saves me about 15 MiB
of process memory usage when running interactively (65 MiB → 50 MiB).

This also makes quick command executions cheaper, particularly since
every REPL loop now involves a clone of the engine state so that we can
recover from a panic. It also reduces memory usage where engine state
needs to be cloned and sent to another thread or kept within an
iterator.

# User-Facing Changes
Shouldn't be any, since it's all internal stuff, but it does change some
public interfaces so it's a breaking change

Make custom value type handling more consistent (#12230)
[Context on
Discord](https://discord.com/channels/601130461678272522/855947301380947968/1219425984990806207)

# Description

- Rename `CustomValue::value_string()` to `type_name()` to reflect its
usage better.
- Change print behavior to always call `to_base_value()` first, to give
the custom value better control over the output.
- Change `describe --detailed` to show the type name as the subtype,
rather than trying to describe the base value.
- Change custom `Type` to use `type_name()` rather than `typetag_name()`
to make things like `PluginCustomValue` more transparent

One question: should `describe --detailed` still include a description
of the base value somewhere? I'm torn on it, it seems possibly useful
for some things (maybe sqlite databases?), but having `describe -d` not
include the custom type name anywhere felt weird. Another option would
be to add another method to `CustomValue` for info to be displayed in
`describe`, so that it can be more type-specific?

# User-Facing Changes

values

Support into string for custom values (#12231)
Context: @abusch is working on a semver plugin with custom values and
wants users to be able to convert them back to strings

# Description
This allows `into string` to work on custom values if their base value
representation could be converted into a string with the same rules.

# User-Facing Changes
`into string` works on custom values.

Unfortunately, I couldn't really demo this with an example, because
there aren't any custom values that can be represented that way
included.

IO and redirection overhaul (#11934)
# Description
The PR overhauls how IO redirection is handled, allowing more explicit
and fine-grain control over `stdout` and `stderr` output as well as more
efficient IO and piping.

To summarize the changes in this PR:
- Added a new `IoStream` type to indicate the intended destination for a
pipeline element's `stdout` and `stderr`.
- The `stdout` and `stderr` `IoStream`s are stored in the `Stack` and to
avoid adding 6 additional arguments to every eval function and
`Command::run`. The `stdout` and `stderr` streams can be temporarily
overwritten through functions on `Stack` and these functions will return
a guard that restores the original `stdout` and `stderr` when dropped.
- In the AST, redirections are now directly part of a `PipelineElement`
as a `Option<Redirection>` field instead of having multiple different
`PipelineElement` enum variants for each kind of redirection. This
required changes to the parser, mainly in `lite_parser.rs`.
- `Command`s can also set a `IoStream` override/redirection which will
apply to the previous command in the pipeline. This is used, for
example, in `ignore` to allow the previous external command to have its
stdout redirected to `Stdio::null()` at spawn time. In contrast, the
current implementation has to create an os pipe and manually consume the
output on nushell's side. File and pipe redirections (`o>`, `e>`, `e>|`,
etc.) have precedence over overrides from commands.

This PR improves piping and IO speed, partially addressing #10763. Using
the `throughput` command from that issue, this PR gives the following
speedup on my setup for the commands below:
| Command | Before (MB/s) | After (MB/s) | Bash (MB/s) |
| --------------------------- | -------------:| ------------:|
-----------:|
| `throughput o> /dev/null` | 1169 | 52938 | 54305 |
| `throughput \| ignore` | 840 | 55438 | N/A |
| `throughput \| null` | Error | 53617 | N/A |
| `throughput \| rg 'x'` | 1165 | 3049 | 3736 |
| `(throughput) \| rg 'x'` | 810 | 3085 | 3815 |

(Numbers above are the median samples for throughput)

This PR also paves the way to refactor our `ExternalStream` handling in
the various commands. For example, this PR already fixes the following
code:
```nushell
^sh -c 'echo -n "hello "; sleep 0; echo "world"' | find "hello world"
```
This returns an empty list on 0.90.1 and returns a highlighted "hello
world" on this PR.

Since the `stdout` and `stderr` `IoStream`s are available to commands
when they are run, then this unlocks the potential for more convenient
behavior. E.g., the `find` command can disable its ansi highlighting if
it detects that the output `IoStream` is not the terminal. Knowing the
output streams will also allow background job output to be redirected
more easily and efficiently.

# User-Facing Changes
- External commands returned from closures will be collected (in most
cases):
  ```nushell
  1..2 | each {|_| nu -c "print a" }
  ```
This gives `["a", "a"]` on this PR, whereas this used to print "a\na\n"
and then return an empty list.

  ```nushell
  1..2 | each {|_| nu -c "print -e a" }
  ```
This gives `["", ""]` and prints "a\na\n" to stderr, whereas this used
to return an empty list and print "a\na\n" to stderr.

- Trailing new lines are always trimmed for external commands when
piping into internal commands or collecting it as a value. (Failure to
decode the output as utf-8 will keep the trailing newline for the last
binary value.) In the current nushell version, the following three code
snippets differ only in parenthesis placement, but they all also have
different outputs:

  1. `1..2 | each { ^echo a }`
     ```
     a
     a
     ╭────────────╮
     │ empty list │
     ╰────────────╯
     ```
  2. `1..2 | each { (^echo a) }`
     ```
     ╭───┬───╮
     │ 0 │ a │
     │ 1 │ a │
     ╰───┴───╯
     ```
  3. `1..2 | (each { ^echo a })`
     ```
     ╭───┬───╮
     │ 0 │ a │
     │   │   │
     │ 1 │ a │
     │   │   │
     ╰───┴───╯
     ```

  But in this PR, the above snippets will all have the same output:
  ```
  ╭───┬───╮
  │ 0 │ a │
  │ 1 │ a │
  ╰───┴───╯
  ```

- All existing flags on `run-external` are now deprecated.

- File redirections now apply to all commands inside a code block:
  ```nushell
  (nu -c "print -e a"; nu -c "print -e b") e> test.out
  ```
This gives "a\nb\n" in `test.out` and prints nothing. The same result
would happen when printing to stdout and using a `o>` file redirection.

- External command output will (almost) never be ignored, and ignoring
output must be explicit now:
  ```nushell
  (^echo a; ^echo b)
  ```
This prints "a\nb\n", whereas this used to print only "b\n". This only
applies to external commands; values and internal commands not in return
position will not print anything (e.g., `(echo a; echo b)` still only
prints "b").

- `complete` now always captures stderr (`do` is not necessary).

Support for all custom value operations on plugin custom values (#12088)
# Description

Adds support for the following operations on plugin custom values, in
addition to `to_base_value` which was already present:

- `follow_path_int()`
- `follow_path_string()`
- `partial_cmp()`
- `operation()`
- `Drop` (notification, if opted into with
`CustomValue::notify_plugin_on_drop`)

There are additionally customizable methods within the `Plugin` and
`StreamingPlugin` traits for implementing these functions in a way that
requires access to the plugin state, as a registered handle model such
as might be used in a dataframes plugin would.

`Value::append` was also changed to handle custom values correctly.

# User-Facing Changes

- Signature of `CustomValue::follow_path_string` and
`CustomValue::follow_path_int` changed to give access to the span of the
custom value itself, useful for some errors.
- Plugins using custom values have to be recompiled because the engine
will try to do custom value operations that aren't supported
- Plugins can do more things 🎉 

# Tests + Formatting
Tests were added for all of the new custom values functionality.

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

# After Submitting
- [ ] Document protocol reference `CustomValueOp` variants:
  - [ ] `FollowPathInt`
  - [ ] `FollowPathString`
  - [ ] `PartialCmp`
  - [ ] `Operation`

- [ ] Document `notify_on_drop` optional field in `PluginCustomValue`

Remove feat extra and include in default (#12140)
# Description
The intended effect of the `extra` feature has been undermined by
introducing the full builds on our release pages and having more
activity on some of the extra commands.

To simplify the feature matrix let's get rid of it and focus our effort
on truly either refining a command to well-specified behavior or
discarding it entirely from the `nu` binary and moving it into plugins.

## Details
- Remove `--features extra` from CI
- Don't explicitly name `extra` in full build wf
- Remove feature extra from build-help scripts
- Update README in `nu-cmd-extra`
- Remove feature `extra`
- Fix previously dead `format pattern` tests
- Relax signature of `to html`
- Fix/ignore `html::test_no_color_flag`
- Remove dead features from `version`
- Refine `to html` type signature

# User-Facing Changes
The commands that were previously only available when building with
`--features extra` will now be available to everyone. This increases the
number of dependencies slightly but has a limited impact on the overall

# Tests + Formatting
Some tests that were left in `nu-command` during cratification were dead
because the feature was not passed to `nu-command` and only to
`nu-cmd-lang` for feature-flag mention in `version`.
Those tests have now been either fixed or ignored in one case.

# After Submitting
There may be places in the documentation where we point to `--features
extra` that will now be moot (apart from the generated command help)

This PR refactors `nu-check` and makes it possible to check module
directories. Also removes the requirement for files to end with .nu: It
was too limiting for module directories and there are executable scripts
[around](https://github.com/nushell/nu_scripts/tree/main/make_release/release-note)
that do not end with .nu, it's a common practice for scripts to omit it.

Other changes are:
* Removed the `--all` flag and heuristic parse because these are
irrelevant now when module syntax is a subset of script syntax (i.e.,
every module can be parsed as script).
* Reduced code duplication and in general tidied up the code
* Replaced unspanned errors with spanned ones.

Fixes: #12054

It's cause by nu always add `/*` if there is a parameter in ls, then `ls

Fix up ctrl+C handling in into_sqlite (#12130)
I noticed that ctrl+C handling wasn't fully wired up in `into sqlite`,
for some data types we were ignoring ctrl+C presses.

I fixed that up and also made sure we roll back the current transaction
when cancelling (without that, I think we leak memory and database
locks).

This PR adds a new evaluator path with callbacks to a mutable trait
object implementing a Debugger trait. The trait object can do anything,
e.g., profiling, code coverage, step debugging. Currently,
entering/leaving a block and a pipeline element is marked with
callbacks, but more callbacks can be added as necessary. Not all
callbacks need to be used by all debuggers; unused ones are simply empty
calls. A simple profiler is implemented as a proof of concept.

The debugging support is implementing by making `eval_xxx()` functions
generic depending on whether we're debugging or not. This has zero
computational overhead, but makes the binary slightly larger (see
benchmarks below). `eval_xxx()` variants called from commands (like
`eval_block_with_early_return()` in `each`) are chosen with a dynamic
dispatch for two reasons: to not grow the binary size due to duplicating
the code of many commands, and for the fact that it isn't possible
because it would make Command trait objects object-unsafe.

In the future, I hope it will be possible to allow plugin callbacks such
that users would be able to implement their profiler plugins instead of
having to recompile Nushell.
[DAP](https://microsoft.github.io/debug-adapter-protocol/) would also be
interesting to explore.

Try `help debug profile`.

## Screenshots

Basic output:

![profiler_new](https://github.com/nushell/nushell/assets/25571562/418b9df0-b659-4dcb-b023-2d5fcef2c865)

To profile with more granularity, increase the profiler depth (you'll
see that repeated `is-windows` calls take a large chunk of total time,
making it a good candidate for optimizing):

![profiler_new_m3](https://github.com/nushell/nushell/assets/25571562/636d756d-5d56-460c-a372-14716f65f37f)

## Benchmarks

### Binary size

Binary size increase vs. main: **+40360 bytes**. _(Both built with
`--release --features=extra,dataframe`.)_

### Time

```nushell
# bench_debug.nu
use std bench

let test = {
    1..100
    | each {
        ls | each {|row| $row.name | str length }
    }
    | flatten
    | math avg
}

print 'debug:'
let res2 = bench { debug profile $test } --pretty
print $res2
```

```nushell
# bench_nodebug.nu
use std bench

let test = {
    1..100
    | each {
        ls | each {|row| $row.name | str length }
    }
    | flatten
    | math avg
}

print 'no debug:'
let res1 = bench { do $test } --pretty
print $res1
```

`cargo run --release -- bench_debug.nu` is consistently 1--2 ms slower
than `cargo run --release -- bench_nodebug.nu` due to the collection
overhead + gathering the report. This is expected. When gathering more
stuff, the overhead is obviously higher.

`cargo run --release -- bench_nodebug.nu` vs. `nu bench_nodebug.nu` I
didn't measure any difference. Both benchmarks report times between 97
and 103 ms randomly, without one being consistently higher than the
other. This suggests that at least in this particular case, when not
running any debugger, there is no runtime overhead.

## API changes

This PR adds a generic parameter to all `eval_xxx` functions that forces
you to specify whether you use the debugger. You can resolve it in two
ways:
* Use a provided helper that will figure it out for you. If you wanted
to use `eval_block(&engine_state, ...)`, call `let eval_block =
get_eval_block(&engine_state); eval_block(&engine_state, ...)`
* If you know you're in an evaluation path that doesn't need debugger
support, call `eval_block::<WithoutDebug>(&engine_state, ...)` (this is
the case of hooks, for example).

I tried to add more explanation in the docstring of `debugger_trait.rs`.

## TODO

- [x] Better profiler output to reduce spam of iterative commands like
`each`
- [x] Resolve `TODO: DEBUG` comments
- [x] Resolve unwraps
- [x] Add doc comments
- [x] Add usage and extra usage for `debug profile`, explaining all
columns

Change the ignore command to use drain() instead of collecting a value (#12120)
# Description

Change the `ignore` command to use `drain()` instead of collecting a
value.

This saves memory usage when piping a lot of output to `ignore`. There's
no reason to keep the output in memory if it's going to be discarded
anyway.

Probably none

Introduce workspace dependencies (#12043)
# Description
This PR introduces [workspaces
dependencies](https://doc.rust-lang.org/cargo/reference/workspaces.html#the-dependencies-table).
The advantages are:
- a single place where dependency versions are declared
- reduces the number of files to change when upgrading a dependency
- reduces the risk of accidentally depending on 2 different versions of
the same dependency

I've only done a few so far. If this PR is accepted, I might continue
and progressively do the rest.
