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.

This allows for:

- [A way to get current command inside pre_execution hook · Issue #6264
· nushell/nushell](https://github.com/nushell/nushell/issues/6264)
- The possibility of *Atuin* to work work *Nushell*. *Atuin* hooks need
to know the current repl input before it is run.

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]

   ·                     │   ╰── cannot find column 'foo'
   ·                     ╰── value originates here

╰───┴───╯
〉[{foo: 1} {foo: 2} {}].foo?.2 | describe

〉[a b c].4? | describe

〉[{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
```

Add is-interactive and is-login to NuVariable and allow running scripts with -i (#8306)
Add two rows in `$nu`, `$nu.is-interactive` and `$nu.is-login`, which
are true when nu is run in interactive and login mode respectively.

The `-i` flag now behaves a bit more like that of bash's, where the any
provided command or file is run without REPL but in "interactive mode".
This should entail sourcing interactive-mode config files, but since we
are planning on overhauling the config system soon, I'm holding off on
that. For now, all `-i` does is set `$nu.is-interactive` to be true.

About testing, I can't seem to find where cli-args get tested, so I
haven't written any new tests for this. Also I don't think there are any
docs that need updating. However if I'm wrong please tell me.

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`

Fix CPU usage info in sys (#8321)
Closes #8264. This PR does a few things to fix the `usage` column in
`sys.cpu`:

1. Sleep a while (~400ms) between calls to `sys.refresh_cpu()`, [as
required by
`sysinfo`](https://docs.rs/sysinfo/latest/sysinfo/trait.SystemExt.html#method.refresh_cpu)
2. Change `sys` to return a `LazyRecord` (so you can do things like `sys
| get host` instantly without waiting for CPU info)
3. Update our `sysinfo` dependency to [fix CPU usage calculations on
Linux](https://github.com/GuillaumeGomez/sysinfo/pull/946)

CPU usage is no longer always reported as zero:

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.

.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/

.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/

And another for when there are files and directories present:
```

Revert #7779 (enables back subcommand completions) (#8102)
# Description

Reverts the PR #7779 which breaks subcommand completions. The issues
#7648 and #7754 thus still need fixing.

This reverts commit 8acced5.

# User-Facing Changes

Enables subcommand completions.

Unfortunately, also brings back the completion panic if alias is shorter
than the command name.

# Tests + Formatting

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

- `cargo fmt --all -- --check` to check standard code formatting (`cargo

- `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

# After Submitting

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

Disable auto-benchmark harness for crates (#8057)
# Description

This disables automatic detection of `#[bench]` and other benchmarks
within the crates. Our benchmarks should all live in `benches`

This fixes a problem with criterion flags and should also reduce the
build requirements for `cargo bench` a bit

Taken from https://github.com/nushell/nushell/pull/7952

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 'number' command for enumeration (#7871)
# Description

This adds a `number` command that will enumerate the input, and add an
`index` and `item` record for each item. The `index` is the number of
the item in the input stream, and `item` is the original value of the
item.

```
> ls | number | get 14
╭───────┬────────────────────────────╮
│ index │ 14                         │

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.

print nushell startup time (#7831)
# Description

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

On my mac in release mode
```
Startup Time: 368ms 429µs 83ns
```
On my mac without a config as `nu --config foo --env-config foo`
```
Startup Time: 11ms 663µs 791ns
```

I could really go either way on this. If people don't like this change,
we don't have to merge it.

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)

Add cursor shape configuration for each edit mode (#7745)
# Description

This PR allows the configuration of cursor shapes in nushell for each
edit mode. This is the change that is in the default_config.nu file.
```
  cursor_shape: {
    emacs: line # block, underscore, line (line is the default)
    vi_insert: block # block, underscore, line (block is the default)
    vi_normal: underscore # block, underscore, line  (underscore is the default)
  }
```

# User-Facing Changes

See above. If you'd prefer a different default, please speak up and let
us know.

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 }] })
                }
        ]
    }]
}
```

### 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 }, Stdout, Expression { expr: String("out.txt"), span: Span { start: 39050, end: 39057 }, ty: String, custom_completion: None }),
        Redirection(Span { start: 39058, end: 39062 }, Stderr, Expression { expr: String("err.txt"), span: Span { start: 39063, end: 39070 }, ty: String, custom_completion: None })] }
```

### Block after
```rust
Pipeline {
    elements: [
        Expression(None, Expression {
            expr: ExternalCall(Expression { expr: String("ls"), span: Span { start: 38526, end: 38528 }, ty: String, custom_completion: None }, [], false),
            span: Span { start: 38525, end: 38528 },
            ty: Any,
            custom_completion: None 
        }),
        // new one! SeparateRedirection
        SeparateRedirection {
            out: (Span { start: 38529, end: 38533 }, Expression { expr: String("out.txt"), span: Span { start: 38534, end: 38541 }, ty: String, custom_completion: None }),
            err: (Span { start: 38542, end: 38546 }, Expression { expr: String("err.txt"), span: Span { start: 38547, end: 38554 }, ty: String, custom_completion: None }) 
        }
    ]
}
