8c507dc984 Revert "Port command examples to long option" (#10597)
Reverts nushell/nushell#10596

Using the long option in examples is going to be confusing as it makes
the reader think the long option is required. It also isn't idiomatic
Nushell.

The examples should be copy-paste-able as idiomatic Nushell, so as such
we shouldn't expand them to the long flag name.

b9ecfeb890 explore: remove unused colour config code (#10570)
Remove code for 2 no-longer-used configuration options in `explore`:
`explore.config.cursor_color` and `explore.config.border_color`.

Think I made these unnecessary in
https://github.com/nushell/nushell/pull/10533 and
https://github.com/nushell/nushell/pull/10270 but missed this code, my
bad. The `explore` config code is a little hard to follow because it
does so many key lookups in hashmaps.

7c274ad4d8 explore: remove 4 line config options (#10562)
This PR removes the `line_head_top`, `line_head_bottom`, `line_shift`,
and `line_index` configuration options from `explore`. These were
previously used to control whether the horizontal+vertical lines in this
`ls | explore -i` screenshot would be displayed:


![image](https://github.com/nushell/nushell/assets/26268125/b705e8a0-935c-40ff-be4a-f119dbae3080)

Now, all lines are displayed (same as the previous default config
values) and this is no longer configurable.

## Context

I'm continuing to chip away at `explore` when I have time. I have a
long-term goal to make `explore` simpler for users+developers. For now
I'm mostly making small incremental changes where I find underused
functionality+configuration and remove it; hopefully eventually this
will make it easier to make larger changes.

I found these specific config options a little hard to understand when
reading `explore` code, and when reading `config.nu` as a user their
behaviour+naming is not obvious. I also think that in the long term,
`explore` styling should inherit most styling from `table` instead of
having its own styling system.

30c331e882 explore: remove Bottom and Right orientations (#10559)
The value rendering code in explore is _very_ flexible; values can be
rendered with orientation `Top`, `Left`, `Bottom`, or `Right`. The
default is `Top` for tables (header at the top) and `Left` for records
(header on the left).

This PR removes `Bottom` and `Right`; they are largely untested,
probably used by nobody, and they complicate the rendering code.

## Testing Performed

I've manually confirmed that tables and records still render the same
ass before, and the `t`/transpose command still works.

78d0e1d0b8 explore: highlight selected cell using background colour instead of cursor (#10533)
More incremental `explore` improvements!

This PR removes the `show_cursor` config from the `explore` command, in
favour of always using the background colour to highlight the selected
cell. I believe this is a better default and I'd like to remove the
`show_cursor` functionality entirely as part of the effort to simplify
`explore`.

The style for selected cells is still configurable. I went with light
blue for the default background colour, it looks OK to me.

e62a77a885 Start removing colour config from explore (#10270)
This PR removes the `explore.try.border_color` config item, and instead
always uses the `separator` colour (the one used for regular table
borders) from the current theme.

The PR also removes some unused `explore.config` bits from the default
config (I missed this in https://github.com/nushell/nushell/pull/10259).

### Future Work

This PR is intentionally small, I want to confirm that I'm on the right
track before I rip out more colour config from `explore`. If all goes
well, expect more PRs like this soon.

### Testing

I confirmed that this works by changing my `separator` colour in
`config.nu`, and also confirmed that nothing breaks if a user still has
`explore.try.border_color` in their config.

f021be623e Exit explore on ctrl+c/d/q (#10257)
Currently, `ctrl+z` is the command to exit `explore` no matter where you
are in the UI. IMO this is a bit unintuitive since that's usually used
to suspend a process.

After this change, `ctrl+c`, `ctrl+d`, and `ctrl+q` all work to exit
`explore`.

I think these are all shortcuts that users might try when attempting to
exit `explore`, and I think we might as well handle them all.

b6189879e3 explore: remove :config, :show-config, :tweak commands (#10259)
More trimming of underused `explore` functionality.

The `explore` command has subcommands that can be run like `:config` or
`:try` or whatnot. This PR removes the `:config`, `:show-config`, and
`:tweak` commands which are all for viewing+modifying config.

These are interesting commands and they were cool experiments, but
ultimately I don't think they fit with our plans for a simplified
`explore`. They'd need a lot more polish if we want to keep them and I
don't think we do. Happy to discuss if I've missed a good reason to keep
these.

c7c6445b03 Remove exit_esc and show_banner config from explore (#10258)
Removing 2 underused config options from `explore`.

`show_banner` controls whether `For help type :help"` is shown in the
message area when `explore is first launched. I don't think there's any
good reason not to show it, it's not a modal dialog or anything.

`exit_esc` controls whether to exit `explore` when `esc` is pressed and
we can't "go up" any further (or at least that's what it's supposed to
do, looking at the code I'm not so sure). IMO we don't need to make this
kind of basic interaction configurable unless there's a really good
reason.

## Context

`explore` is complicated and we want to overhaul its design. It will be
easier to make meaningful changes if `explore` is a little slimmer
first, so I'm trying to pare back unused/underused code and config as a
starting point.

I'm gonna be making more PRs like this, I'll try to keep them
small+self-contained.

6cdfee3573 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 :)

3d73287ea4 add support for Vim motions in explore (#9966)
related to
- https://github.com/nushell/nushell/issues/7819

# Description
this PR does not quite address
https://github.com/nushell/nushell/issues/7819 because it does not
implement configurable keybindings for `explore` but rather only adds
support for Vim-like motions *out of the box*.

# User-Facing Changes
in *view* and *cursor* modes,
- `h`, `j`, `k` and `l` give standard Qwerty-based Vim motions
- `g` and `G` go to the top and the end respectively
- `u` and `d` scroll up and down

> **Note**
> the bindings do not support the use of modifiers for now, so it's not
`c-u` and `c-d` which scroll pages but rather `u` and `d`

1e3e034021 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.

8da27a1a09 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}`.

Sorry that you've had the issues.
I've actually encountered them yesterday too (seems like they have
appeared after some refactoring in the middle) but was not able to fix
that rapid.

Created a bunch of tests.

cc: @fdncred 

Note:

This option will be certainly slower then a default ones. (could be
fixed but ... maybe later).
Maybe it shall be cited somewhere.

PS: Haven't tested on a wrapped/expanded tables.

6c730def4b 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.

Minor improvement in compile time ~0.5 sec observed as `nu-command`

a92949b5c3 nu-explore: Fix pipeline rendering (#9137)
Must be fixed (but I would check).

I wonder if it was a regression caused by `Value::LazyRecord`.
I mean likely the issue was before the refactoring I did.

8d8b011702 Bump tabled dependency to 0.11 (#8922)
close? #8060

Quite a bit of refactoring took place.
I believe a few improvements to collapse/expand were made.

I've tried to track any performance regressions and seems like it is
fine.

I've noticed something different now with default configuration path or
something in this regard?
So I might missed something while testing because of this.

Requires some oversight.

aded2c1937 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

# User-Facing Changes

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

d8478ca690 Clean up unnecessary macro use (#8607)
Some minor code cleanup.

We've accumulated a few macros over the years that arguably don't need
to be macros. This PR removes 4 macros by either:
1. Inlining the macro
2. Replacing the macro with a local function
3. Replacing the macro with a closure

21b84a6d65 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?
╭───┬───╮

╰───┴───╯
〉[{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.

a52386e837 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.

58529aa0b2 Benchmark each pipeline element (#7854)
# Description

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

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

# User-Facing Changes

Shouldn't change any existing behavior.
