Fix replacement closures for update, insert, and upsert (#11258)
# Description
This PR addresses #11204 which points out that using a closure for the
replacement value with `update`, `insert`, or `upsert` does not work for
lists.

# User-Facing Changes
- Replacement closures should now work for lists in `upsert`, `insert`,
and `update`. E.g., `[0] | update 0 {|i| $i + 1 }` now gives `[1]`
instead of an unhelpful error.
- `[1 2] | insert 4 20` no longer works. Before, this would give `[1, 2,
null, null, 20]`, but now it gives an error. This was done to match the
intended behavior in `Value::insert_data_at_cell_path`, whereas the
behavior before was probably unintentional. Following
`Value::insert_data_at_cell_path`, inserting at the end of a list is
also fine, so the valid indices for `upsert` and `insert` are
`0..=length` just like `Vec::insert` or list inserts in other languages.

# Tests + Formatting
Added tests for `upsert`, `insert`, and `update`:
- Replacement closures for lists, list streams, records, and tables
- Other list stream tests

Convert Shellerror::GenericError to named fields (#11230)
# Description

Replace `.to_string()` used in `GenericError` with `.into()` as
`.into()` seems more popular

Replace `Vec::new()` used in `GenericError` with `vec![]` as `vec![]`

Spread operator in record literals (#11144)
Goes towards implementing #10598, which asks for a spread operator in
lists, in records, and when calling commands (continuation of #11006,
which only implements it in lists)

# Description
This PR is for adding a spread operator that can be used when building
records. Additional functionality can be added later.

Changes:

- Previously, the `Expr::Record` variant held `(Expression, Expression)`
pairs. It now holds instances of an enum `RecordItem` (the name isn't
amazing) that allows either a key-value mapping or a spread operator.
- `...` will be treated as the spread operator when it appears before
`$`, `{`, or `(` inside records (no whitespace allowed in between) (not
implemented yet)
- The error message for duplicate columns now includes the column name
itself, because if two spread records are involved in such an error, you
can't tell which field was duplicated from the spans alone

`...` will still be treated as a normal string outside records, and even
in records, it is not treated as a spread operator when not followed
immediately by a `$`, `{`, or `(`.

# User-Facing Changes
Users will be able to use `...` when building records.

```
> let rec = { x: 1, ...{ a: 2 } }
> $rec
╭───┬───╮
│ x │ 1 │
│ a │ 2 │
╰───┴───╯
> { foo: bar, ...$rec, baz: blah }
╭─────┬──────╮
│ foo │ bar  │
│ x   │ 1    │
│ a   │ 2    │
│ baz │ blah │
╰─────┴──────╯
```
If you want to update a field of a record, you'll have to use `merge`
instead:
```
> { ...$rec, x: 5 }
Error: nu:🐚:column_defined_twice

  × Record field or table column used twice: x
   ╭─[entry #2:1:1]
 1 │  { ...$rec, x: 5 }
   ·       ──┬─  ┬
   ·         │   ╰── field redefined here

Support o>>, e>>, o+e>> to append output to an external file (#10764)
# Description
Close: #10278

This pr introduces `o>>`, `e>>`, `o+e>>` to allow redirection to append
to a file.
Examples:
```nushell
echo abc o>> a.txt
echo abc o>> a.txt
cat asdf e>> a.txt
cat asdf e>> a.txt
cat asdf o+e>> a.txt
```

~~TODO:~~
~~1. currently internal commands with `o+e>` redirect to a variable is
broken: `let x = "a.txt"; echo abc o+e> $x`, not sure when it was
introduced...~~
~~2. redirect stdout and stderr with append mode doesn't supported yet:
`cat asdf o>>a.txt e>>b.ext`~~

~~For these 2 items, I'd like to fix them in different prs.~~

add shape ExternalResolved to show found externals via syntax highlighting in the repl (#11135)
# Description

This PR enables a new feature that shows which externals are found in
your path via the syntax highlighter as you type.

![external_resolved](https://github.com/nushell/nushell/assets/343840/e5fa91f0-6fac-485c-8afc-5711fc0ed9bc)

This idea could use some improvement where it caches the items in your
path and on some trigger, expires that cache and creates a new on. Right
now, all it does is call the `which` crate on every character you type.
This could be problematic if you have hundreds of paths in your PATH or
if some of your paths in your Path point to extraordinarily slow file
systems. WSL pointing to Windows comes to mind. Either way, I've thrown
it up here for people to try and provide feedback. I think the novelty
of showing what is valid and what isn't is pretty cool. I believe
fish-shell also does this, IIRC.

Redirect: support redirect stderr with piping stdout to next commands. (#10851)
# Description
Fixes: #10271

Given the following script:
```shell
# test.sh
echo aaaaa
echo bbbbb 1>&2
echo cc
```

This pr makes the following command possible:
```nushell
bash test.sh err> /dev/null | lines | each {|line| $line | str length}
```


## General idea behind the change:
When nushell redirect stderr message to external file
1. it take stdout of external stream, and pass this stream to next
command, so it won't block next pipeline command from running.
2. relative stderr stream are handled by `save` command

These two streams are handled separately, so we need to delegate a
thread to `save` command, or else we'll have a chance to hang nushell,
we have meet a similar before: #5625.

### One case to consider
What if we're failed to save to an external stream? (Like we don't have
a permission to save to a file)?
In this case nushell will just print a waning message, and don't stop
the following scripts from running.

# User-Facing Changes
## Before
```nushell
❯ bash test2.sh err> /dev/null | lines | each {|line| $line | str length}
aaaaa
cc
```

## After
```nushell
❯ bash test2.sh err> /dev/null | lines | each {|line| $line | str length}
╭───┬───╮
│ 0 │ 5 │
│ 1 │ 2 │
╰───┴───╯
```

BTY, after this pr, the following commands are impossible either, it's
important to make sure that the implementation doesn't introduce too
much costs:
```nushell
❯ echo a e> a.txt e> a.txt
Error:   × Can't make stderr redirection twice
   ╭─[entry #1:1:1]
 1 │ echo a e> a.txt e> a.txt
   ·                 ─┬
   ·                  ╰── try to remove one

`ShellError::FlagNotFound` had a note that said it may be removable so
this PR removes it instead of updating it to named fields per #10700

I can't see this error being used since it was introduced with #4364. I
can't find why or where it was used before that date, though. There was
a large merge with that PR but I can't penetrate the secrets of git to
find out where its earlier history went.

Refactor Value cell path functions to fix bugs (#11066)
# Description
Slightly refactors the cell path functions (`insert_data_at_cell_path`,
etc.) for `Value` to fix a few bugs and ensure consistent behavior.
Namely, case (in)sensitivity now applies to lazy records just like it
does for regular `Records`. Also, the insert behavior of `insert` and
`upsert` now match, alongside fixing a few related bugs described below.
Otherwise, a few places were changed to use the `Record` API.

# Tests
Added tests for two bugs:
- `{a: {}} | insert a.b.c 0`: before this PR, doesn't create the
innermost record `c`.
- `{table: [[col]; [{a: 1}], [{a: 1}]]} | insert table.col.b 2`: before
this PR, doesn't add the field `b: 2` to each row.

Add Argument::span() and Call::arguments_span() (#10983)
# Description

These make it easy to make a Span that covers an entire argument and the
span of all arguments in a Call.

Call::arguments_span() is useful for errors where a command may accept
arguments or the pipeline, but not both.

Argument::span() is useful for errors where an arguments is incompatible
with one or more other arguments.

In particular, I wish to use this to create an error for an
implementation of #9563 that either allows arguments to set limits:

```nushell
limits set RLIMIT_NOFILE --soft 255 --hard 1024
```

Or pipeline:

```nushell
{name: RLIMIT_NOFILE, soft: 255} | limits set
```

But not both:

```
❯ [{name: RLIMIT_NOFILE, soft: 255, hard: 1024}] | limits set AS --soft 5 --hard 5
Error: nu:🐚:incompatible_parameters

  × Incompatible parameters.

add "default" table theme (#11072)
# Description

This PR fixes a minor bug that prevented this command from running.
```nushell
table --list | each {|r| print ($r); print (ls | first 3 | table --theme $r)}
```
Here's the output now of the first few themes.

![image](https://github.com/nushell/nushell/assets/343840/21bc8942-5106-4b6a-8905-e90d6cb9a153)

It prevented it from running because "default" wasn't a real table
theme. Now "default" is a synonym of rounded.

Also tweaked the error message when a bad theme name is provided.

Implement Display for CellPath (#11023)
# Description
Because `CellPath::into_string` takes a borrowed `self`, I renamed it to
`to_string` to follow Rust [API
guidelines](https://rust-lang.github.io/api-guidelines/naming.html#ad-hoc-conversions-follow-as_-to_-into_-conventions-c-conv).
This then triggered the clippy lint
[inherent_to_string](https://rust-lang.github.io/rust-clippy/master/index.html#/inherent_to_string),
which is... correct! The current `CellPath::into_string` is being used
as if it were the `Display` implementation for `CellPath`.

# User-Facing Changes
Breaking API change for `nu-protocol`, since `CellPath::into_string` was
removed.

Improve case insensitivity consistency (#10884)
# Description

Add an extension trait `IgnoreCaseExt` to nu_utils which adds some case
insensitivity helpers, and use them throughout nu to improve the
handling of case insensitivity. Proper case folding is done via unicase,
which is already a dependency via mime_guess from nu-command.

In actuality a lot of code still does `to_lowercase`, because unicase
only provides immediate comparison and doesn't expose a `to_folded_case`
yet. And since we do a lot of `contains`/`starts_with`/`ends_with`, it's
not sufficient to just have `eq_ignore_case`. But if we get access in
the future, this makes us ready to use it with a change in one place.

Plus, it's clearer what the purpose is at the call site to call
`to_folded_case` instead of `to_lowercase` if it's exclusively for the
purpose of case insensitive comparison, even if it just does
`to_lowercase` still.

# User-Facing Changes

- Some commands that were supposed to be case insensitive remained only
insensitive to ASCII case (a-z), and now are case insensitive w.r.t.
non-ASCII characters as well.

Use record API in more parts of nu-protocol (#10928)
# Description

This is pretty complementary/orthogonal to @IanManske 's changes to
`Value` cellpath accessors in:
- #10925
- to a lesser extent #10926

## Steps
- Use `R.remove` in `Value.remove_data_at_cell_path`
- Pretty sound after #10875 (tests mentioned in commit message have been
removed by that)
- Update `did_you_mean` helper to use iterator
- Change `Value::columns` to return iterator
  - This is not a place of honor
- Use `Record::get` in `Value::get_data_by_key`
# User-Facing Changes
None intentional, potential edge cases on duplicated columns could
change (considered undefined behavior)

Refactor and fix Config<->Value mechanism (#10896)
# Description
Our config exists both as a `Config` struct for internal consumption and
as a `Value`. The latter is exposed through `$env.config` and can be
both set and read.
Thus we have a complex bug-prone mechanism, that reads a `Value` and
then tries to plug anything where the value is unrepresentable in
`Config` with the correct state from `Config`.

The parsing involves therefore mutation of the `Value` in a nested
`Record` structure. Previously this was wholy done manually, with
indices.
To enable deletion for example, things had to be iterated over from the
back. Also things were indexed in a bunch of places. This was hard to
read and an invitation for bugs.

With #10876 we can now use `Record::retain_mut` to traverse the records,
modify anything that needs fixing, and drop invalid fields.

# Parts:

- Error messages now consistently use the correct spans pointing to the
problematic value and the paths displayed in some messages are also
aligned with the keys used for lookup.
- Reconstruction of values has been fixed for:
	- `table.padding`
	- `buffer_editor`
	- `hooks.command_not_found`
	- `datetime_format` (partial solution)
- Fix validation of `table.padding` input so value is not set (and
underflows `usize` causing `table` to run forever with negative values)
- New proper types for settings. Fully validated enums instead of
strings:
  - `config.edit_mode` -> `EditMode` 
  	- Don't fall back to vi-mode on invalid string
  - `config.table.mode` -> `TableMode`
- there is still a fall back to `rounded` if given an invalid
`TableMode` as argument to the `nu` binary
  - `config.completions.algorithm` -> `CompletionAlgorithm`
  - `config.error_style` -> `ErrorStyle`
    - don't implicitly fall back to `fancy` when given an invalid value.
- This should also shrink the size of `Config` as instead of 4x24 bytes
those fields now need only 4x1 bytes in `Config`
- Completely removed macros relying on the scope of `Value::into_config`
so we can break it up into smaller parts in the future.
- Factored everything into smaller files with the types and helpers for
particular topics.
- `NuCursorShape` now explicitly expresses the `Inherit` setting.
conversion to option only happens at the interface to `reedline`

Use Vec for Closure captures (#10940)
# Description
Changes the `captures` field in `Closure` from a `HashMap` to a `Vec`
and makes `Stack::captures_to_stack` take an owned `Vec` instead of a
borrowed `HashMap`.

This eliminates the conversion to a `Vec` inside `captures_to_stack` and
makes it possible to avoid clones altogether when using an owned
`Closure` (which is the case for most commands). Additionally, using a
`Vec` reduces the size of `Value` by 8 bytes (down to 72).

This does not yet make the assumption that columns are always
duplicated. Follow the existing logic here

- Use saner record API in `nu-engine/src/eval.rs`
- Use checked record construction in `nu-engine/src/scope.rs`
- Use `values` iterator in `nu-engine/src/scope.rs`
- Use `columns` iterator in `nu_engine::get_columns()`
- Start using record API in `value/mod.rs`
- Use `.insert` in `eval_const.rs` Record code

Disallow duplicated columns in table literals (#10875)
# Description
Pretty much all operations/commands in Nushell assume that the column
names/keys in a record and thus also in a table (which consists of a
list of records) are unique.
Access through a string-like cell path should refer to a single column
or key/value pair and our output through `table` will only show the last
mention of a repeated column name.

```nu
[[a a]; [1 2]]
╭─#─┬─a─╮
│ 0 │ 2 │
╰───┴───╯
```

While the record parsing already either errors with the
`ShellError::ColumnDefinedTwice` or silently overwrites the first
occurence with the second occurence, the table literal syntax `[[header
columns]; [val1 val2]]` currently still allowed the creation of tables
(and internally records with more than one entry with the same name.

This is not only confusing, but also breaks some assumptions around how
we can efficiently perform operations or in the past lead to outright
bugs (e.g. #8431 fixed by #8446).

This PR proposes to make this an error.
After this change another hole which allowed the construction of records
with non-unique column names will be plugged.

## Parts
- Fix `SE::ColumnDefinedTwice` error code
- Remove previous tests permitting duplicate columns
- Deny duplicate column in table literal eval
- Deny duplicate column in const eval
- Deny duplicate column in `from nuon`

# User-Facing Changes
`[[a a]; [1 2]]` will now return an error:

```
Error: nu:🐚:column_defined_twice

  × Record field or table column used twice
   ╭─[entry #2:1:1]
 1 │ [[a a]; [1 2]]
   ·   ┬ ┬
   ·   │ ╰── field redefined here
   ·   ╰── field first defined here
   ╰────
```

this may under rare circumstances block code from evaluating.

Furthermore this makes some NUON files invalid if they previously
contained tables with repeated column names.

# Tests + Formatting
Added tests for each of the different evaluation paths that materialize
tables.

Reuse Closure type in Value::Closure (#10894)
# Description
Reuses the existing `Closure` type in `Value::Closure`. This will help
with the span refactoring for `Value`. Additionally, this allows us to
more easily box or unbox the `Closure` case should we chose to do so in
the future.

Add Record::remove/retain/retain_mut (#10876)
# Description
While we have now a few ways to add items or iterate over the
collection, we don't have a way to cleanly remove items from `Record`.

This PR fixes that:

- Add `Record.remove()` to remove by key
- makes the assumption that keys are unique, so can not be used
universally, yet (see #10875 for an important example)
- Add naive `Record.retain()` for inplace removal
- This follows the two separate `retain`/`retain_mut` in the Rust std
library types, compared to the value-mutating `retain` in `indexmap`
- Add `Record.retain_mut()` for one-pass pruning

Continuation of #10841 

# User-Facing Changes
None yet.

Add common map-like API to nu_protocol::Record (#10841)
# Description

> Our `Record` looks like a map, quacks like a map, so let's treat it
with the API for a map

Implement common methods found on e.g. `std::collections::HashMap` or
the insertion-ordered [indexmap](https://docs.rs/indexmap).

This allows contributors to not have to worry about how to get to the
relevant items and not mess up the assumptions of a Nushell record.

## Record assumptions
- `cols` and `vals` are of equal length
- for all practical purposes, keys/columns should be unique

## End goal

The end goal of the upcoming series of PR's is to allow us to make
`cols` and `vals` private.
Then it would be possible to exchange the backing datastructure to best
fit the expected workload.
This could be statically (by finding the best balance) or dynamically by
using an `enum` of potential representations.

## Parts
- Add validating explicit part constructor
`Record::from_raw_cols_vals()`
- Add `Record.columns()` iterator
- Add `Record.values()` iterator
- Add consuming `Record.into_values()` iterator
- Add `Record.contains()` helper
- Add `Record.insert()` that respects existing keys
- Add key-based `.get()`/`.get_mut()` to `Record`
- Add `Record.get_index()` for index-based access
- Implement `Extend` for `Record` naively
- Use checked constructor in `record!` macro
- Add `Record.index_of()` to get index by key

# User-Facing Changes
None directly

# Developer facing changes
You don't have to roll your own record handling and can use a familiar
API

# Tests + Formatting
No explicit unit tests yet. Wouldn't be too tricky to validate core
properties directly.
Will be exercised by the following PRs using the new
methods/traits/iterators.

Convert more examples and tests to record! macro (#10840)
# Description
Use `record!` macro instead of defining two separate `vec!` for `cols`
and `vals` when appropriate.
This visually aligns the key with the value.
Further more you don't have to deal with the construction of `Record {
cols, vals }` so we can hide the implementation details in the future.

## State

Not covering all possible commands yet, also some tests/examples are
better expressed by creating cols and vals separately.

# User/Developer-Facing Changes
The examples and tests should read more natural. No relevant functional
change

# Bycatch

Where I noticed it I replaced usage of `Value` constructors with
`Span::test_data()` or `Span::unknown()` to the `Value::test_...`
constructors. This should make things more readable and also simplify
changes to the `Span` system in the future.

Allow filesystem commands to access files with glob metachars in name (#10694)
(squashed version of #10557, clean commit history and review thread)

Fixes #10571, also potentially: #10364, #10211, #9558, #9310,


# Description
Changes processing of arguments to filesystem commands that are source
paths or globs.
Applies to `cp, cp-old, mv, rm, du` but not `ls` (because it uses a
different globbing interface) or `glob` (because it uses a different
globbing library).

The core of the change is to lookup the argument first as a file and
only glob if it is not. That way,
a path containing glob metacharacters can be referenced without glob
quoting, though it will have to be single quoted to avoid nushell
parsing.

Before: A file path that looks like a glob is not matched by the glob
specified as a (source) argument and takes some thinking about to
access. You might say the glob pattern shadows a file with the same
spelling.
```
> ls a*

> ## Note -- a[bc]d *not* copied, and seemingly hard to access.

> cp --verbose 'a[[]bc[]]d' dest
copied /home/bobhy/src/rust/work/r4/a[bc]d to /home/bobhy/src/rust/work/r4/dest/a[bc]d
```
Before_2: if file has glob metachars but isn't a valid pattern, user
gets a confusing error:

```
> touch 'a[b'
> cp 'a[b' dest
Error:   × Pattern syntax error near position 30: invalid range pattern
   ╭─[entry #13:1:1]
 1 │ cp 'a[b' dest
   ·    ──┬──
   ·      ╰── invalid pattern
   ╰────
```

After: Args to cp, mv, etc. are tried first as literal files, and only
as globs if not found to be files.

```
> cp --verbose 'a[bc]d' dest
copied /home/bobhy/src/rust/work/r4/a[bc]d to /home/bobhy/src/rust/work/r4/dest/a[bc]d
> cp --verbose '[a][bc]d' dest
copied /home/bobhy/src/rust/work/r4/abd to /home/bobhy/src/rust/work/r4/dest/abd
copied /home/bobhy/src/rust/work/r4/acd to /home/bobhy/src/rust/work/r4/dest/acd
```
After_2: file with glob metachars but invalid pattern just works.
(though Windows does not allow file name to contain `*`.).

```
> cp --verbose 'a[b' dest
copied /home/bobhy/src/rust/work/r4/a[b to /home/bobhy/src/rust/work/r4/dest/a[b
```

So, with this fix, a file shadows a glob pattern with the same spelling.
If you have such a file and really want to use the glob pattern, you
will have to glob quote some of the characters in the pattern. I think
that's less confusing to the user: if ls shows a file with a weird name,
s/he'll still be able to copy, rename or delete it.

# User-Facing Changes
Could break some existing scripts. If user happened to have a file with
a globbish name but was using a glob pattern with the same spelling, the
new version will process the file and not expand the glob.

Remove cd w/ abbreviations (#10588)
# Description

This removes the old style "cd with abbreviations" that would attempt to
guess what directory you wanted to `cd` to. This would sometimes have
false positives, so we left it off by default in the config.

In the current main, we have much-improved path completions
(https://github.com/nushell/nushell/pull/10543) so you can now do `cd
a/b<tab>` and get a much better experience (because you can see the
directory you're about to cd to). This removes the need for the previous
abbreviation system.

# User-Facing Changes

This does remove the old abbreviation system. It will likely mean that
old config files that have settings for abbreviations will now get
errors.

update: here's an example of the error you'll see:

# User-Facing Changes
You can now either pass a string with the name of the executable or a

`$env.config.buffer_editor`/`$env.EDITOR`/`$env.VISUAL`

Both the external buffer editor of reedline (by default bound to
`Ctrl-o`) and the commands `config nu` and `config env` will respect
those variables in the following order:
1. `$env.config.buffer_editor`
2. `$env.EDITOR`
3. `$env.VISUAL`

Example:
```
$env.EDITOR = "nvim"                      # The system-wide EDITOR is neovim
$env.config.buffer_editor = ["vim" "-p2"] # Force vim to open two tabs (not particularly useful)
$env.config.buffer_editor = null          # Unset `buffer_editor` -> Uses `$env.EDITOR` ergo nvim

Add kitty protocol config to nushell (#10540)
# Description

Support keyboard enhancement protocol as implemented by Kitty console,
hence Kitty protocol.

This PR enables Nushell to use keybinding that is not available before,
such as Ctrl+i (that alias to Tab) or Ctrl+e (that alias to Esc, likely
I mistaken). After this PR merged and you set `use_kitty_protocol`
enabled, if your console app support Kitty protocol (WezTerm, Kitty,
etc.) you will be able to set more fine-grained keybinding.

For Colemak users, this feature is a blessing, because some Ctrl+[hjkl]
that previously unmap-able to Ctlr+[hnei] now it is.

# User-Facing Changes

This adds `use_kitty_protocol` config which defaults to false. When set
to `true`, it enables kitty protocol on the line editor when supported,
or else it warns.

remove the $nothing variable (#10478)

- https://github.com/nushell/nushell/pull/9918

thanks to @jntrnr and their super useful tips on this PR, i learned
about the parser + evaluation, so 🙏

# Description
because we already have `null` as the value of the type `nothing` and as
a followup to the two other attempts of mine, i propose to remove the
redundant `$nothing` built-in variable 😋

this PR is the first step, deprecating `$nothing`.
a followup PR will remove it altogether and wait for 0.87 👍 

⚙️ **details**: a new `NOTHING_VARIABLE_ID = 3` has been added,
parsing `$nothing` will create it, finally a `Value::Nothing` will be
produced and a warning will be reported.

this PR already fixes the `toolkit.nu` module so that it does not throw
a bunch of warnings each time 👌

# User-Facing Changes
`$nothing` is now deprecated and will be removed in 0.87

# Tests + Formatting
tests have been updated, especially
- `nothing_fails_string`
- `nothing_fails_int`
which use a variable called `nil` now to make sure `nothing` does not
support cell paths 👍

This required adjusting the visibility of several parts.

close #10393

PS: Maybe as a separate issue (good candidate for `GOOD FIRST ISSUE`)
add a config option to change a default `...` truncation sign to a
custom? (which would be applicable not only for `--abbreviated` but all
kind of tables)

Update internal use of decimal to float (#10333)
# Description
We made the decision that our floating point type should be referred to
as `float` over `decimal`.
Commands were updated by #9979 and #10320

Now make the internal codebase consistent in referring to this data type
as `float`.

Work for #10332

# User-Facing Changes

`decimal` has been removed as a type name/symbol. 

Instead of 
```nushell
def foo [bar: decimal] decimal -> decimal {}
```
use 
```nushell
def foo [bar: float] float -> float {}
```

Potential effect of `SyntaxShape`'s `Display` implementation now also
referring to `float` instead of `decimal`

# Details
- Rename `SyntaxShape::Decimal` to `Float`
- Update `Display for SyntaxShape` to `float`
- Update error message + fn name in dataframe code
- Fix docs in command examples
- Rename tests that are float specific
- Update doccomment on `SyntaxShape`
- Update comment in script

Remove python-like string multiplication (#10293)
# Description
Currently we support "multiplication" of strings, resulting in a terse
way to repeat a particular string.
This can have unintended side effects when dealing with mixed data (e.g.
after parsing data that is not all numbers).
Furthermore as we frequently fall-back to strings while parsing source
code, this introduced a runaway edge case in const evaluation (#10212)

Work for #10233

## Details
- Remove python-like string multiplication.
- Workaround for indentation
  - This should probably be addressed with a purpose built command
- Remove special const-eval error test

# User-Facing Changes
**Major breaking change!**
`"string" * 42` will stop working. (This was used for example in the
stdlib)

We should bless a good alternative before landing this

Remove pythonic int * list behavior (#10292)
# Description
The pythonism that multiplying a scalar integer with a list results in a
repeated concatenation of the list, is ambiguous with other possible
interpretations and thus actively harmful to clear semantics in nushell.

Another possible reading of this scalar/vector product would be trying
to perform elementwise multiplication with the scalar.

Before we bless this alternative as a more reasonable design the best
course of action is to remove this pythonism.

Work related to #10233


# User-Facing Changes
Breaking change as this turns `int * list` or `list * int` into hard
errors.

`into decimal` raises a deprecation warning, will be removed soon.
Use `into float` as the new functionally identical command instead.

remove profiling from nushell's hot loop (#10325)
# Description

This removes pipeline element profiling. This could be a useful feature,
but pipeline elements are going to be the most sensitive to in terms of
performance, as `eval_block` and how pipelines are built is one of the
hot loops inside of the eval engine.

# User-Facing Changes

Removes pipeline element profiling.

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.

update format date when using %x %X %r (#10272)
# Description

Apparently some strftime formats are already localized and when you
"double localize" them, they don't work. This PR fixes that so that %x
%X %r %c don't go through the localization step.

Example: %x %X
### Before
```nushell
❯ date now | format date "%x %X %p"
09/08/2023 08 AM
```
### After
```nushell
❯ date now | format date "%x %X %p"
09/08/23 08:09:14 AM
```

I started to make one format_datetime to rule them all but one returns a
string and one returns a value. If we convert to the string, we lose the
nice error messages. If we change to value, more code has to be changed
elsewhere. So, I decided to just leave two functions.

rename the types with spaces in them to use - (#9929)
# Description
before this PR,
```nushell
> $.a.b | describe
cell path
```
which feels inconsistent with the `cell-path` type annotation, like in
```nushell
> def foo [x: cell-path] { $x | describe }; foo $.a.b
cell path
```

this PR changes the name of the "cell path" type from `cell path` to
`cell-path`

# User-Facing Changes
`cell path` is now `cell-path` in the output of `describe`.
this might be a breaking change in some scripts.

same goes with
- `list stream` -> `list-stream`
- `match pattern` -> `match-pattern`

# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
-  `toolkit test`
-  `toolkit test stdlib`

this PR adds a new `cell_path_type` test to make sure it stays equal to
`cell-path` in the future.

* `out+err>` is cached by `parse_expression` but not this, which may be
a potential problem.
* `Commond(None, ..)` remains panic for future bug report because I
don't actually know when/how does it happen

add plugin path when there are no signatures (#10201)
# Description

This PR adds the ability to have a `$nu.plugin-path` even when you
plugins are registered and it also should work with `nu -n --no-stdlib`.

### Before
It would give an error
```
│ plugin-path        │ IOError("Could not get plugin signature location")             │
```

### After
It returns the proper path, like this for me
```
│ plugin-path        │ /Users/fdncred/Library/Application Support/nushell/plugin.nu   │
```

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

As part of the refactor to split spans off of Value, this moves to using

matching span out of Value directly.

## Things to be determined

- ~Review naming. `errors.style` is not _that_ consistent with the rest
of the code. Menus use a `style` record, but table rendering mode is set
via `mode`.~ As it's a single config, we're using `error_style` for now.
- Should this kind of setting be toggable with one single parameter?
`accessibility.no_decorations` or similar, which would adjust the style
of both errors and tables accordingly.

# User-Facing Changes

No changes by default, errors will be rendered differently if
`error_style` is set to `simple`.

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.

Fix duration type to not report months or years (#9632)
<!--

- this PR should close #xxxx
- fixes #xxxx

you can also mention related issues, PRs or discussions!
-->
This PR should close #8036, #9028 (in the negative) and #9118.

Fix for #9118 is a bit pedantic.  As reported, the issue is:
```
> 2023-05-07T04:08:45+12:00 - 2019-05-10T09:59:12+12:00
3yr 12month 2day 18hr 9min 33sec
```
with this PR, you now get:
```
> 2023-05-07T04:08:45+12:00 - 2019-05-10T09:59:12+12:00
208wk 1day 18hr 9min 33sec
```
Which is strictly correct, but could still fairly be called "weird date
arithmetic".

# Description
* [x] Abide by constraint that Value::Duration remains a number of
nanoseconds with no additional fields.
* [x] `to_string()` only displays weeks .. nanoseconds. Duration doesn't
have base date to compute months or years from.
* [x] `duration | into record` likewise only has fields for weeks ..
nanoseconds.
* [x] `string | into duration` now accepts compound form of duration
to_string() (e.g '2day 3hr`, not just '2day')
* [x] `duration | into string` now works (and produces the same
representation as to_string(), which may be compound).

# User-Facing Changes
## duration -> string -> duration
Now you can "round trip" an arbitrary duration value: convert it to a
string that may include multiple time units (a "compound" value), then
convert that string back into a duration. This required changes to
`string | into duration` and the addition of `duration | into string'.
```
> 2day + 3hr
2day 3hr # the "to_string()" representation (in this case, a compound value)
> 2day + 3hr | into string
2day 3hr # string value
> 2day + 3hr | into string | into duration
2day 3hr # round-trip duration -> string -> duration
```
Note that `to nuon` and `from nuon` already round-tripped durations, but
use a different string representation.

## potentially breaking changes
* string rendering of a duration no longer has 'yr' or 'month' phrases.
* record from `duration | into record` no longer has 'year' or 'month'
fields.
The excess duration is all lumped into the `week` field, which is the
largest time unit you can
convert to without knowing the datetime from which the duration was
calculated.

Scripts that depended on month or year time units on output will need to
be changed.

### Examples
```
> 365day
52wk 1day
## Used to be: 
## 1yr

> 365day | into record
╭──────┬────╮
│ week │ 52 │
│ day  │ 1  │
│ sign │ +  │
╰──────┴────╯

## used to be:
##╭──────┬───╮
##│ year │ 1 │
##│ sign │ + │
##╰──────┴───╯

> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns)
56wk 6day 6hr 7min 8sec 9ms 10µs 11ns
## used to be:
## 1yr 1month 3day 6hr 7min 8sec 9ms 10µs 11ns
## which looks reasonable, but was actually only correct in 75% of the years and 25% of the months in the last 4 years.

> (365day + 4wk + 5day + 6hr + 7min + 8sec + 9ms + 10us + 11ns) | into record
╭─────────────┬────╮
│ week        │ 56 │
│ day         │ 6  │
│ hour        │ 6  │
│ minute      │ 7  │
│ second      │ 8  │
│ millisecond │ 9  │
│ microsecond │ 10 │
│ nanosecond  │ 11 │
│ sign        │ +  │
╰─────────────┴────╯
```
Strictly speaking, these changes could break an existing user script.
Losing years and months as time units is arguably a regression in
behavior.

Also, the corrected duration calculation could break an existing script
that was calibrated using the old algorithm.

Auto-expand table based on terminal width (#9934)
# Description

This PR adds back the functionality to auto-expand tables based on the
terminal width, using the logic that if the terminal is over 100 columns
to expand.

This sets the default config value in both the Rust and the default
nushell config.

To do so, it also adds back the ability for hooks to be strings of code
and not just code blocks.

Fixed a couple tests: two which assumed that the builtin display hook
didn't use a table -e, and one that assumed a hook couldn't be a string.

Fix #9928. When parsing input/output types `nothing` was incorrectly
coerced to `any`. This is addressed by changing how
[to_type](0ad1ad4277/crates/nu-protocol/src/syntax_shape.rs (L121))
method handles `nothing` syntax shape. Also `range` syntax shape is
addressed the same way.

# User-Facing Changes
`nothing` and `range` are correctly displayed in help and strictly
processed by type checking. This will break definitions that were not in
fact output nothing or range and incorrect uses of functions which input
nothing or range.

Examples of correctly defined functions:

Add an option to set header on border (style) (#9920)
fix #9796

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.

This is just draft since we're seeing some issues with the latest fixes
to table drawing that just landed with #9796. We're hoping to get these
fixed, but if we're not able to fix them before the next release, we'll
need to revert (hence this PR, just in case we need it).

Add an option to move header on borders (#9796)
A patch to play with.
Need to make a few tests after all.

The question is what shall be done with `table.mode = none`, as it has
no borders.

```nu
$env.config.table.move_header = true
```

Relative: #8248 

After this pr, user can define const variable inside a module.

![image](https://github.com/nushell/nushell/assets/22256154/e3e03e56-c4b5-4144-a944-d1b20bec1cbd)

And user can export const variables, the following screenshot shows how
it works (it follows
https://github.com/nushell/nushell/issues/8248#issuecomment-1637442612):

![image](https://github.com/nushell/nushell/assets/22256154/b2c14760-3f27-41cc-af77-af70a4367f2a)

## About the change
1. To make module support const, we need to change `parse_module_block`
to support `const` keyword.
2. To suport export `const`, we need to make module tracking variables,
so we add `variables` attribute to `Module`
3. During eval, the const variable may not exists in `stack`, because we
don't eval `const` when we define a module, so we need to find variables
which are already registered in `engine_state`

## One more thing to note about the const value.
Consider the following code
```
module foo { const b = 3; export def bar [] { $b } }
use foo bar
const b = 4;
bar
```
The result will be 3 (which is defined in module) rather than 4. I think
it's expected behavior.

It's something like [dynamic
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Dynamic-Binding-Tips.html)
vs [lexical
binding](https://www.gnu.org/software/emacs/manual/html_node/elisp/Lexical-Binding.html)
in lisp like language, and lexical binding should be right behavior
which generates more predicable result, and it doesn't introduce really
subtle bugs in nushell code.

What if user want dynamic-binding?(For example: the example code returns
`4`)
There is no way to do this, user should consider passing the value as
argument to custom command rather than const.

## TODO
- [X] adding tests for the feature.
- [X] support export const out of module to use.

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`.

Remove Signature.vectorizes_over_list entirely (#9777)
# Description
With the current typechecking logic this property has no effect.
It was only used in the example testing, and provided some indication of
this vectorizing property.
With #9742 all commands that previously declared it have explicit list
signatures. If we want to get it back in the future we can reconstruct
it from the signature.

Simplifies the example testing a bit.

# User-Facing Changes
Causes a breaking change for plugins that previously declared it. While
this causes a compile fail, this was already broken by our more
stringent type checking.
This will be a good reminder for plugin authors to update their
signature as well to reflect the more stringent type checking.

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.

sync default config / env with default behaviour without any configuration (#9676)
related PRs and issues
- supersedes https://github.com/nushell/nushell/pull/9633
- should close https://github.com/nushell/nushell/issues/9630

# Description
this PR updates the `default_config.nu` config file and the `config.rs`
module in `nu_protocol` so that the default behaviour of Nushell,
without any config, and the one with `default_config.nu` and
`default_env.nu` are the same.

## changelog
- 3e2bfc9bb: copy the structure of `default_config.nu` inside the
implementation of `Default` in the `config.rs` module for easier check
of the default values
- e25e5ccd6: sync all the *simple* config fields, i.e. the
non-structured ones
- ae7e8111c: set the `display_output` hook to always run `table`
- a09a1c564: leave only the default menus => i've removed
`commands_menu`, `vars_menu` and `commands_with_description`

## todo
- [x] ~~check the defaults in `$env.config.explore`~~ done in 173bdbba5
and b9622084c
- [x] ~~check the defaults in `$env.config.color_config`~~ done in
c411d781d => the theme is now `{}` by default so that it's the same as
the default one with `--no-config`
- [x] ~~check the defaults `$env.config.keybindings`~~ done in 715a69797
- already available with the selected mode: `completion_previous`,
`next_page`, `undo_or_previous_page`, `yank`, `unix-line-discard` and
`kill-line`, e.g. in *vi* mode, `unlix-line-discard` is done in NORMAL
mode with either `d0` from the end of the line or `dd` from anywhere in
the line and `kill-line` is done in NORMAL mode with `shift + d`. these
bindings are available by default in *emacs* mode as well.
- previously with removed custom menus: `commands_menu`, `vars_menu` and
`commands_with_description`
- [x] ~~check `$env.config.datetime_format`~~ done in 0ced6b8ec => as
there is no *human* format for datetimes, i've commented out both
`$env.config.datetime_format` fields
- [x] ~~fix `default_env.nu`~~ done in 67c215011

# User-Facing Changes
this should not change anything, just make sure the default behaviour of
Nushell and the `default_config.nu` are in sync.

Clean up tests containing unnecessary cwd: tokens (#9692)
# Description
The working directory doesn't have to be set for those tests (or would
be the default anyways). When appropriate also remove calls to the
`pipeline()` function. In most places kept the diff minimal and only
removed the superfluous part to not pollute the blame view. With simpler
tests also simplified things to make them more readable overall (this
included removal of the raw string literal).

add match guards (#9621)
## description

this pr adds [match
guards](https://doc.rust-lang.org/reference/expressions/match-expr.html#match-guards)
to match patterns
```nushell
match $x {
   _ if $x starts-with 'nu' => {},
   $x => {}
}
```

these work pretty much like rust's match guards, with few limitations:

1. multiple matches using the `|` are not (yet?) supported
 
```nushell
match $num {
    0 | _ if (is-odd $num) => {},
    _ => {}
}
```

2. blocks cannot be used as guards, (yet?)

```nushell
match $num {
    $x if { $x ** $x == inf } => {},
     _ => {}
}
```

## checklist
- [x] syntax
- [x] syntax highlighting[^1]
- [x] semantics
- [x] tests
- [x] clean up

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.

improve subtyping (#9614)
# Description

the current subtyping rule needs you to define the record entries in the
same order as declared in the annotation. this pr improves that

now
```nushell
{ name: 'Him', age: 12 } 

# ,

{ age: 100, name: 'It' }

# and

{ name: 'Red', age: 69, height: "5-8" }

# will all match

record<name: string, age: int>

# previously only the first one would match
```

however, something like

```nushell
{ name: 'Her' } # will not


# and

{ name: 'Car', wheels: 5 }
```

EDIT: applied JT's suggestion

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.

remove let-env, focus on mutating $env (#9574)
# Description

For years, Nushell has used `let-env` to set a single environment
variable. As our work on scoping continued, we refined what it meant for
a variable to be in scope using `let` but never updated how `let-env`
would work. Instead, `let-env` confusingly created mutations to the
command's copy of `$env`.

So, to help fix the mental model and point people to the right way of
thinking about what changing the environment means, this PR removes
`let-env` to encourage people to think of it as updating the command's
environment variable via mutation.

Before:

```
let-env FOO = "BAR"
```

Now:

```
$env.FOO = "BAR"
```

It's also a good reminder that the environment owned by the command is
in the `$env` variable rather than global like it is in other shells.

# User-Facing Changes

BREAKING CHANGE BREAKING CHANGE

This completely removes `let-env FOO = "BAR"` so that we can focus on
`$env.FOO = "BAR"`.

Improve type hovers (#9515)
# Description

This PR does a few things to help improve type hovers and, in the
process, fixes a few outstanding issues in the type system. Here's a
list of the changes:

* `for` now will try to infer the type of the iteration variable based
on the expression it's given. This fixes things like `for x in [1, 2, 3]
{ }` where `x` now properly gets the int type.
* Removed old input/output type fields from the signature, focuses on
the vec of signatures. Updated a bunch of dataframe commands that hadn't
moved over. This helps tie things together a bit better
* Fixed inference of types from subexpressions to use the last
expression in the block
* Fixed handling of explicit types in `let` and `mut` calls, so we now
respect that as the authoritative type

I also tried to add `def` input/output type inference, but unfortunately
we only know the predecl types universally, which means we won't have
enough information to properly know what the types of the custom
commands are.

# User-Facing Changes

Script typechecking will get tighter in some cases
Hovers should be more accurate in some cases that previously resorted to
any.

Skip strum in regular nu-protocol build (#9445)
# Description
`derive(EnumIter)` is only required to run completeness tests.
Thus make the derive conditional on test and move `strum` and
`strum_macros` to the dev dependencies.

## Is it worth it?

Removing this derive does not change the binary size (checked via `cargo
bloat --crates` from `cargo-bloat`).
Compile time change is below a second so hard to judge based on a single
run of `cargo clean --profile dev; cargo build --timings`
Unsure if this negatively impacts how incremental compilation can
recompile when you switch between `cargo build`/`run` and `cargo test`
in your local workflow.

To get rid of `strum`/`strum_macros` as a proc macro crate we would need
to also remove it from `reedline`.
Further more a crate in the `polars` dependency tree uses `strum`
(curently not as relevant for the 1.0 build).

clean up config by removing legacy options (#9496)
# Description

This PR cleans up the deprecated legacy config options that were
deprecated in nushell version 0.72.0. These are the config points that
were in the root of the config but also duplicated in the nested
structures. For instance `use_ls_colors` was in the root of the config
and also in the `ls.use_ls_colors` nested structure. This was originally
done to preserve backwards compatibility when nested structures were
introduced in the config file.

Here's a list of the legacy config points that were removed.

- `use_ls_colors` - previously replaced with `ls.use_ls_colors`
- `rm_always_trash` - previously replaced with `rm.always_trash`
- `history_file_format` - previously replaced with `history.file_format`
- `sync_history_on_enter` - previously replaced with
`history.sync_on_enter`
- `max_history_size` - previously replaced with `history.max_size`
- `quick_completions` - previously replaced with `completions.quick`
- `partial_completions` - previously replaced with `completions.partial`
- `max_external_completion_results` - previously replaced with
`completions.external.max_results`
- `completion_algorithm` - previously replaced with
`completions.algorithm`
- `case_sensitive_completions` - previously replaced with
`completions.case_sensitive`
- `enable_external_completion` - previously replaced with
`completions.external.enable`
- `external_completer` - previously replaced with
`completions.external.completer`
- `table_mode` - previously replaced with `table.mode`
- `table_index_mode` - previously replaced with `table.index_mode`
- `table_trim` - previously replaced with `table.trim`
- `show_clickable_links_in_ls` - previously replaced with
`ls.clickable_links`
- `cd_with_abbreviations` - previously replaced with `cd.abbreviations`
- `filesize_metric` - previously replaced with `filesize.metric`
- `filesize_format` - previously replaced with `filesize.format`
- `cursor_shape_vi_insert` - previously replaced with
`cursor_shape.vi_insert`
- `cursor_shape_vi_normal` - previously replaced with
`cursor_shape.vi_normal`
- `cursor_shape_emacs` - previously replaced with `cursor_shape.emacs`

Removes log_level from the config since it doesn't do anything any
longer. We moved log-level to a nushell parameter some time ago.

Renames history_isolation to isolation in the config.nu for consistency.

Fixes a couple bugs where values weren't being set in the "//
Reconstruct" sections (history_isolation, table_show_empty).

Reorganized/Moved things around a tiny bit and added a few comments.

# User-Facing Changes

history.histor_isolation is now history.isolation.
If anyone is still using the legacy config points, deprecated since
0.72.0 2022-11-29, their config will break.

Revert #8395 "Treat empty pipelines as pass-through" (#9472)
In my view we should revert nushell/nushell#8395 for now

## Potentially inconsistent application of semantic change
#8395 (1d5e7b441b) was loosening the type
coercion rules significantly, to let missing data / void returns that
were either expressed by `PipelineData::Empty` or the `Value::nothing`
be accept by specifically those commands/operations that made use of
`PipelineData::into_iter_strict()`. This could apply the new rules
inconsistently.

## Turning explicit failures into silent continuations
Furthermore the effect of this breaking change to the missing data
semantics could make previous errors into silent failures.
This could either just reduce the effectiveness of teaching error
messages in interactive use:

### Contrived example before
```bash
> cd . | where blah
Error: nu:🐚:only_supports_this_input_type

  × Input type not supported.
   ╭─[entry #13:1:1]
 1 │ cd . | where blah
   ·        ──┬──┬
   ·          │  ╰── input type: null
   ·          ╰── only list, binary, raw data or range input data is supported
   ╰────
```
### ...after, with #8395
```bash
> cd . | where blah
╭────────────╮
│ empty list │
╰────────────╯
```

In rare cases people could already try to rely on catching an error of a
downstream command to actually deal with the missing data, so it would
be a breaking change for their existing code.

## Problem with `PipelineData::into_iter_strict()`

Maybe this makes `_strict` a bit of a misnomer for this particular
iterator construction.
Further we did not actively test the `PipelineData::empty` branch before

![grafik](https://github.com/nushell/nushell/assets/15833959/c377bf1d-d47c-4c25-a342-9a348539f242)

## Parsimonious solution exists

For the motivating issue https://github.com/nushell/nushell/issues/8393
there already exists a fix that makes `ls` more consistent with the type
system by returning an empty `Value::List`

Treat empty pipelines as pass-through (#8395)
# Description

This allows empty pipelines to pass their emptiness through a filter.
This helps fix issues like trying to run a filter on an `ls` in an empty
directory. It also feels a bit more reasonable that a filter filters
what is *there* but doesn't require something to be there.

fixes #8393

# User-Facing Changes

No breaking changes (that I know of). Should allow filtering to be a
little less surprising with emptiness.

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.

# User-Facing Changes

Reverts the HashMap -> ahash change.

Added comments to support API docs for the `nu-plugin` crate. Removed a
few items that I'd expect should only be used internally to Nushell from
the documentation and reduced the visibility of some items that did not
need to be public.

Feature: Userland LazyRecords (#8332)
# Description
Despite the innocent-looking title, this PR involves quite a few backend
changes as the existing LazyRecord trait was not at all friendly towards
the idea of these values being generated on the fly from Nu code.

In particular, here are a few changes involved:
- The LazyRecord trait now involves a lifetime `'a`, and this lifetime
is used in the return value of `get_column_names`. This means it no
longer returns `'static str`s (but implementations still can return
these). This is more stringent on the consumption side.
- The LazyRecord trait now must be able to clone itself via a new
`clone_value` method (as requiring `Clone` is not object safe). This
pattern is borrowed from `Value::CustomValue`.
- LazyRecord no longer requires being serde serializable and
deserializable.

These, in hand, allow for the following:
- LazyRecord can now clone itself, which means that they don't have to
be collected into a Record when being cloned.
- This is especially useful in Stack, which is cloned on each repl line
and in a few other cases. This would mean that _every_ LazyRecord
instance stored in a variable would be collected in its entirety and
cloned, which can be catastrophic for performance. See: `let nulol =
$nu`.
- LazyRecord's columns don't have to be static, they can have the same
lifetime of the struct itself, so different instances of the same
LazyRecord type can have different columns and values (like the new
`NuLazyRecord`)
- Serialization and deserialization are no longer meaningless, they are
simply less.

I would consider this PR very "drafty", but everything works. It
probably requires some cleanup and testing, though, but I'd like some
eyes and pointers first.

# User-Facing Changes
New command. New restrictions are largely internal. Maybe there are some
plugins affected?

Example of new command's usage:
```
lazy make --columns [a b c] --get-value { |name| print $"getting ($name)"; $name | str upcase }
```

You can also trivially implement something like `lazy make record` to
take a record of closures and turn it into a getter-like lazy struct:
```
def "lazy make record" [
    record: record
] {
    let columns = ($record | columns)

    lazy make --columns $columns --get-value { |col| do ($record | get $col) }
}
```

Open to bikeshedding. `lazy make` is similar to `error make` which is
also in the core commands. I didn't like `make lazy` since it sounded
like some transformation was going on.

# Tour for reviewers
Take a look at LazyMake's examples. They have `None` as the results, as
such they aren't _really_ correct and aren't being tested at all. I
didn't do this because creating the Value::LazyRecord is a little tricky
and didn't want to risk messing it up, especially as the necessary
variables aren't available when creating the examples (like stack and
engine state).

Also take a look at NuLazyRecord's get_value implementation, or in
general. It uses an Arc<Mutex<_>> for the stack, which must be accessed
mutably for eval_block but get_value only provides us with a `&self`.
This is a sad state of affairs, but I don't know if there's a better
way.

On the same code path, we also have pipeline handling, and any pipeline
that isn't a Pipeline::Value will return Value::nothing. I believe
returning a Value::Error is probably better, or maybe some other
handling. Couldn't decide on which ShellError to settle with for that
branch.

The "unfortunate casualty" in the columns.rs file. I'm not sure just how
bad that is, though, I simply had to fight a little with the borrow
checker.

A few leftover comments like derives, comments about the now
non-existing serde requirements, and impls. I'll definitely get around
to those eventually but they're in atm

Should NuLazyRecord implement caching? I'm leaning heavily towards
**yes**, this was one of the main reasons not to use a record of
closures (besides convenience), but maybe it could be opt-out. I'd
wonder about its implementation too, but a simple way would be to move a
HashMap into the mutex state and keep cached values there.

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

                    redirection: (Span { start: 147949, end: 147957 }, LiteCommand { comments: [], parts: [Span { start: 147958, end: 147965 }]})
                }
            ]
        }
    ]
}
```
### Block before

        Redirection(Span { start: 39058, end: 39062 }, StdoutAndStderr, Expression { expr: String("out.txt"), span: Span { start: 39050, end: 39057 }, 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, }
}

〉use ~/work/dflts.nu

Change type of flag defaults to Option<Value> (#9085)
# Description
Follow-up of #8940. As @bobhy pointed out, it makes sense for the
behaviour of flags to match the one for positional arguments, where
default values are of type `Option<Value>` instead of
`Option<Expression>`.

# User-Facing Changes
The same ones from the original PR:
- Flag default values will now be parsed as constants.
- If the default value is not a constant, a parser error is displayed.

# Tests + Formatting

A [new
test](e34e2d35f4/src/tests/test_engine.rs (L338-L344))
has been added to verify the new restriction.

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

allow records to have type annotations (#8914)
# Description
follow up to #8529
cleaned up version of #8892 

- the original syntax is okay
```nu
def okay [rec: record] {}
```
- you can now add type annotations for fields if you know
  them before hand
```nu
def okay [rec: record<name: string>] {}
```

- you can specify multiple fields
```nu
def okay [person: record<name: string age: int>] {}

# an optional comma is allowed
def okay [person: record<name: string, age: int>] {}
```

- if annotations are specified, any use of the command will be type
  checked against the specified type
```nu
def unwrap [result: record<ok: bool, value: any>] {}

unwrap {ok: 2, value: "value"}

# errors with

Error: nu::parser::type_mismatch

  × Type mismatch.
   ╭─[entry #4:1:1]
 1 │ unwrap {ok: 2, value: "value"}
   ·         ───────┬─────
   ·                    ╰── expected record<ok: bool, value: any>, found record<ok: int, value: string>
   ╰────
```
> here the error is in the `ok` field, since `any` is coerced into any
type
> as a result `unwrap {ok: true, value: "value"}` is okay

- the key must be a string, either quoted or unquoted
```nu
def err [rec: record<{}: list>] {}

# errors with
Error:
  × `record` type annotations key not string
   ╭─[entry #7:1:1]
 1 │ def unwrap [result: record<{}: bool, value: any>] {}
   ·                            ─┬
   ·                             ╰── must be a string
   ╰────
```

- a key doesn't have to have a type in which case it is assumed to be
`any`
```nu
def okay [person: record<name age>] {}

def okay [person: record<name: string age>] {}
```

- however, if you put a colon, you have to specify a type
```nu
def err [person: record<name: >] {}

# errors with
Error: nu::parser::parse_mismatch

  × Parse mismatch during operation.
   ╭─[entry #12:1:1]
 1 │ def unwrap [res: record<name: >] { $res }
   ·                             ┬
   ·                             ╰── expected type after colon
   ╰────
```

# User-Facing Changes
**[BREAKING CHANGES]**
- this change adds a field to `SyntaxShape::Record` so any plugins that
used it will have to update and include the field. though if you are
unsure of the type the record expects, `SyntaxShape::Record(vec![])`
will suffice

update ast to support output to json (#8962)
# Description
This PR changes the `ast` command to be able to output `--json` as well
as `nuon` (default) with "pretty" and "minified" output. I'm hoping this
functionality will be usable in the vscode extension for semantic
tokenization and highlighting.

# User-Facing Changes
There's a new `--json`/`-j` option. Prior version output of nuon is
maintained as default.

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

uses that span to find the parsed block for that file. The end result
should, in theory, be identical but doesn't require any reparsing or
creating new blocks/new definitions that aren't needed.

This drops the sg.nu benchmark from:
```

unify the *-BuiltinVar parser errors (#8944)
# Description

this pr condenses `MutBuiltinVar`, `LetBuiltinVar` and `ConstBuiltinVar`
into one error:
```nu
Error: nu::parser::name_is_builtin_var

  × `in` used as variable name.
   ╭─[entry #69:1:1]
 1 │ let in = 420
   ·     ─┬
   ·      ╰── already a builtin variable
   ╰────
  help: 'in' is the name of a builtin Nushell variable and cannot be used
        as a variable name
```

it also fixes this case which was previously not handled
```nu
let $nu = 420 # this variable would have been 'lost'

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

Allow arguments for the last flag in short flag batch (#8808)
# Description
_Fixes #5923_

Currently `nushell` doesn't allow short flag batches to contain
arguments, despite this being a common pattern in commands like `git
commit -am 'My commit message'`. This PR relaxes this so that the last
flag in the batch can take an argument.

# User-Facing Changes
- `nu::parser::short_flag_arg_cant_take_arg` has been replaced by
`nu::parser::only_last_flag_in_batch_can_take_arg` and is displayed when
a flag other then the last in a short flag batch takes an argument.

# Tests + Formatting
- Both
[`test_parser.rs`](48af0ebc3c/crates/nu-parser/tests/test_parser.rs (L640-L704))
and
[`test_known_external.rs`](48af0ebc3c/src/tests/test_known_external.rs (L42-L61))
have been updated to test the new allowed and disallowed scenarios.

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....

improve operation mismatch errors (#8800)
# Description

This improves the operation mismatch error in a few ways:

* We now detect if the left-hand side of the operation is at fault, and
show a simpler error/error message if it is
* Removed the unhelpful hint
* Updated the error text to make it clear what types are causing the
issue

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.

Remove autoprinting of loop block values (#8618)
# Description

This removes autoprinting the final value of a loop, much in the same
spirit as not autoprinting values at the end of statements. As we fix
these corner cases, it becomes more consistent that to print to the
screen in a script, you use the `print` command.

This gives a noticeable performance improvement as a bonus.

Before:
```
C:\Source\nushell〉 for x in 1..10 { $x }
1
2
3
4
5
6
7
8
9
10
```
Now:
```
C:\Source\nushell〉 for x in 1..10 { $x }
C:\Source\nushell〉
```

Change comparison operators to allow nulls (#8617)
Prior to this PR, the less/greater than operators (`<`, `>`, `<=`, `>=`)
would throw an error if either side was null. After this PR, these
operators return null if either side (or both) is null.

### Examples
```bash 
1 < 3       # true
1 < null    # null
null < 3    # null
null < null # null
```

### Motivation

JT [asked the C#
folks](https://discord.com/channels/601130461678272522/615329862395101194/1086137515053957140)
and this is apparently the approach they would choose for comparison
operators if they could start from scratch.

This PR makes `where` more convenient to use on jagged/missing data. For
example, we can now filter on columns that may not be present in every
row:
```
> [{foo: 123} {}] | where foo? > 10
╭───┬─────╮
│ # │ foo │
├───┼─────┤
│ 0 │ 123 │
╰───┴─────╯

Speed up tight loop benchmarks (#8609)
# Description

This does a few speedups for tight loops:
* Caches the DeclId for `table` so we don't look it up. This means users
can't easily replace the default one, we might want to talk about this
tradeoff. The lookup for finding `table` in a tight loop is currently
pretty heavy. Might be another way to speed this up.
* `table` no longer pre-calculates the width. Instead, it only
calculates the width when printing a table or record.
* Use more efficient way of collecting the block of each loop
* When printing output, only get the config when needed

Combined, this drops the runtime from a million loop tight iteration
from 1sec 8ms to 236ms.

Move variables to var stack (#8604)
# Description

This moves the representation of variables on the stack to a Vec, which
more closely resembles a stack. For small numbers of variables live at
any one point, this tends to be more efficient than a HashMap. Having a
stack-like vector also allows us to remember a stack position,
temporarily push variables on, then quickly drop the stack back to the
original size when we're done. We'll need this capability to allow
matching inside of conditions.

On this mac, a simple run of:

`timeit { mut x = 1; while $x < 1000000 { $x += 1 } }`

Went from 1 sec 86 ms, down to 1 sec 2 ms. Clearly, we have a lot more
ground we can make up in looping speed 😅 but it's nice that for fixing
this to make matching easier, we also get a win in terms of lookup speed
for small numbers of variables.

Make HTTP requests cancellable when trying to connect (#8591)
Closes #8585.

Prior to this change, the `http` commands could get stuck for 30s while
attempting to make a connection to a remote server. After this change,
`ctrl+c` works as expected:


![image](https://user-images.githubusercontent.com/26268125/227395505-c2d5b19d-6228-4eac-836f-c0c3426b0c19.png)

To make this work, we perform blocking `ureq` calls in a background
thread and poll the channel while checking `ctrl+c`.

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

Cell paths: make optional path members short-circuit (#8554)
This is a follow-up to https://github.com/nushell/nushell/pull/8379 and
https://github.com/nushell/nushell/discussions/8502.

This PR makes it so that the new `?` syntax for marking a path member as
optional short-circuits, as voted on in the
[8502](https://github.com/nushell/nushell/discussions/8502) poll.
Previously, `{ foo: 123 }.bar?.baz` would raise an error:

```
> { foo: 123 }.bar?.baz
  × Data cannot be accessed with a cell path
   ╭─[entry #15:1:1]
 1 │ { foo: 123 }.bar?.baz
   ·                   ─┬─
   ·                    ╰── nothing doesn't support cell paths
   ╰────
   ```

Here's what was happening:

1. The `bar?` path member access returns `nothing` because there is no field named `bar` on the record
2. The `baz` path member access fails when trying to access a `baz` field on that `nothing` value

After this change, `{ foo: 123 }.bar?.baz` returns `nothing`; the failed `bar?` access immediately returns `nothing` and the `baz` access never runs.

This PR also bundles a small refactor for histogram forbidden column
names exception, previous implementation forgot a column name in the
message, to avoid this, I'm re-using the same array for checking and
error display

feat: add a command_not_found hook (#8314)
# Description
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).

Disable pipeline echo (#8292)
# Description

Change behavior of block evaluation to not print result of intermediate
commands.
Previously result of every but last pipeline in a block was printed to
stdout, and last one was returned

![image](https://user-images.githubusercontent.com/17511668/222550110-3f62fbed-432c-4b46-b9b1-4cb45a1f893e.png)
With this change results of intermediate pipelines are discarded after
they finish and the last one is returned as before:

![image](https://user-images.githubusercontent.com/17511668/222550346-f1e74f80-f6b6-4aa3-98d6-888ea4cb4915.png)
Now one should use `print` explicitly to print something to stdout

![image](https://user-images.githubusercontent.com/17511668/222923955-fda0d77b-41b4-4f91-a80f-12b0a1880c05.png)

**Note, that this behavior is not limited to functions!** The scope of
this change are all blocks. All of the below are executed as blocks and
thus exibited this behavior in the same way:

![image](https://user-images.githubusercontent.com/17511668/222924062-342c15de-4273-4bf5-8b39-fe6e3aa96076.png)

With this change outputs for all types of blocks are cleaned:

Additional flags for commands from csv and from tsv (#8398)
# Description

Resolves issue #8370

Adds the following flags to commands `from csv` and `from tsv`:
- `--flexible`: allow the number of fields in records to be variable
- `-c --comment`: a comment character to ignore lines starting with it
- `-q --quote`: a quote character to ignore separators in strings,
defaults to '\"'
- `-e --escape`: an escape character for strings containing the quote
character

Internally, the `Value` struct has an additional helper function
`as_char` which converts it to a single `char`

# User-Facing Changes

The single quoted string `'\t'` can no longer be used as a parameter for
the flag `--separator '\t'` as it is interpreted as a two-character
string. One needs to use from now on the flag with a double quoted
string like so: `-s "\t"` which correctly interprets the string as a
single `char`.

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
```

# 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.
