Fix sandboxing of redirection tests (#11407)
When running `cargo test --workspace` a file `crates/nu-command/a.txt`
remained which we also saw as an accidential additions in some commits.

Searching for `a.txt` narrowed it down that
`redirection_keep_exit_codes` was not sandboxed in a temporary directory
and created this file.

Went through redirection tests and placed them in a `Playground` to get
sandboxing `dirs` for `nu!(cwd:`.
For those tests where redirection fails and no file should be created
now I added a check that no file is created on accident.


- Sandbox `redirection_keep_exit_codes` test
- Sandbox `no_duplicate_redirection` test
- Check that no redirect file is created on error
- Sandbox `redirection_should_have_a_target` test

Enforce required, optional, and rest positional arguments start with an uppercase and end with a period. (#11285)
# Description

This updates all the positional arguments (except with
`--features=dataframe` or `--features=extra`) to start with an uppercase
letter and end with a period.

Part of #5066, specifically [this
comment](/nushell/nushell/issues/5066#issuecomment-1421528910)

Some arguments had example data removed from them because it also
appears in the examples.

There are other inconsistencies in positional arguments I noticed while
making the tests pass which I will bring up in #5066.

# User-Facing Changes

Positional arguments are now consistent

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

Match ++= capabilities with ++ (#11130)

# User-Facing Changes

It is now possible to do `$list ++= 1` (appending a single element).
Similarly, this can be done:

When using redirection, if a command generates non-zero exit code, the script should stop running (#11191)
# Description
Fixes: #11153

To make sure scripts stop from running on non-zero exit code, we need to
invoke `might_consume_external_result` on
`PipelineData::ExternalStream`, so it can tell nushell if this command
exists with non-zero exit code.

And this pr also adjusts some test cases.

# User-Facing Changes
```nushell
^false out> /dev/null; print "ok"
```

After this pr, it shouldn't print ok.

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.~~

Cp target expansion (#11152)
# Description
This PR addresses issue with cp brough up on
[discord](https://discord.com/channels/601130461678272522/614593951969574961/1177669443917189130)
where target of cp is not correctly expanded.
If one has directory `test` with file `file.txt` in it then the
following command (in one line or inside a `do` block):
```nu
cd test; let file = 'copy.txt'; cp file.txt $file
```
will create a `copy.txt` in `.` not in `test` instead. This happens
because target of `cp` is a variable which is not expanded unlike a
string literal

# User-Facing Changes
`cp` will correctly parse realative target paths

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

Add is-terminal to determine if stdin/out/err are a terminal (#10970)
# Description

I'm not sure if "is-terminal" is the best name for this command as there
is also "term size". Uses
[`is_terminal()`](https://doc.rust-lang.org/stable/std/io/trait.IsTerminal.html#tymethod.is_terminal)
which is cross-platform.

Possible alternative names:
* `term is-tty --stdout`
* `term is-tty stdout`
* `term is-terminal stdout`

If multiple streams are provided an error is returned. The error span
covers all arguments as the incompatible one is not known. This may be
new?

Fixes #10517

# User-Facing Changes

* Add `is-terminal` to check if stdin, stdout, or stderr are a terminal
(TTY)

# Tests + Formatting

The nu tests always redirect stdin, stdout, and stderr so a positive
test case is not possible without extra work

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

# After Submitting

The new command will be added automatically

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 mktemp command (#11005)
closes #10845 

I've opened this a little prematurely to get some questions answered
before I cleanup the code.

As I started trying to better understand GNUs `mktemp` I've realized its
kind of peculiar and we might want to change its behavior to introduce
it to nushell.

#### quiet and dry run

Does it make sense to keep the `quiet` and `dry_run` flags? I don't
think so. The GNU documentation says this about the dry run flag "Using
the output of this command to create a new file is inherently unsafe, as
there is a window of time between generating the name and using it where
another process can create an object by the same name." So yeah why keep
it? As far as quiet goes, does it make sense to silence the errors in
nushell?

#### other confusing flags

According to the [gnu
docs](https://www.gnu.org/software/coreutils/manual/html_node/mktemp-invocation.html),
the `-t` flag is deprecated and the `-p`/ `--tempdir` are the same flag
with the only difference being `--tempdir` takes an optional path, Given
that, I've broken the `-p` away from `--tempdir`. Now there is one
switch `--tmpdir`/`-t` and one named param `--tmpdir-path`/`-p`.

GNU mktemp
```
  -p DIR, --tmpdir[=DIR]  interpret TEMPLATE relative to DIR; if DIR is not
                        specified, use $TMPDIR if set, else /tmp.  With
                        this option, TEMPLATE must not be an absolute name;
                        unlike with -t, TEMPLATE may contain slashes, but
                        mktemp creates only the final component
  -t                  interpret TEMPLATE as a single file name component,
                        relative to a directory: $TMPDIR, if set; else the
                        directory specified via -p; else /tmp [deprecated]

```
to
nushell mktemp
```
  -p, --tmpdir-path <Filepath> # named param, must provide a path
  -t, --tmpdir                 # a switch
```

Is this a terrible idea?

What should I do?

Refactor drop columns to fix issues (#10903)
# Description
This PR refactors `drop columns` and fixes issues #10902 and #6846.
Tables with "holes" are now handled consistently, although still
somewhat awkwardly. That is, the columns in the first row are used to
determine which columns to drop, meaning that the columns displayed all
the way to the right by `table` may not be the columns actually being
dropped. For example, `[{a: 1}, {b: 2}] | drop column` will drop column
`a` instead of `b`. Before, this would give a list of empty records.

# User-Facing Changes
`drop columns` can now take records as input.

Add exec command for Windows (#11001)
# Description
Based of the work and discussion in #10844, this PR adds the `exec`
command for Windows. This is done by simply spawning a
`std::process::Command` and then immediately exiting via
`std::process::exit` once the child process is finished. The child
process's exit code is passed to `exit`.

# User-Facing Changes
The `exec` command is now available on Windows, and there should be no
change in behaviour for Unix systems.

Update description and error types for split-by (#10865)
# Description

`split-by` only works on a `Record`, the error type was updated to
match, and now uses a more-specific type. (Two type fixes for the price
of one!)

The `usage` was updated to say "record" as well

# User-Facing Changes

* Providing the wrong type to `split-by` now gives an error messages
with the correct required input type

Previously:

```
❯ ls | get name | split-by type
Error:   × unsupported input
   ╭─[entry #267:1:1]
 1 │ ls | get name | split-by type
   ·      ─┬─
   ·       ╰── requires a table with one row for splitting
   ╰────
```

With this PR:

```
❯ ls | get name | split-by type
Error: nu:🐚:type_mismatch

  × Type mismatch.
   ╭─[entry #1:1:1]

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.

as we can see in the [documentation of

- `str downcase` incorrectly converts only ASCII characters

7ac5a01e2f/crates/nu-command/src/strings/str_/case/downcase.rs (L124)

this PR uses `str.to_lower_case` instead of `str.to_ascii_lowercase` in

readd update flag to cp command (#10824)
# Description
- this PR should close #10819


# User-Facing Changes
Behaviour is similar to pre 0.86.0 behaviour of the cp command and
should as such not have a user-facing change, only compared to the
current version, were the option is readded.


# After Submitting
I guess the documentation will be automatically updated and as this
feature is no further highlighted, probably, no more work will be needed
here.

# Considerations
coreutils actually allows a third option:
```
pub enum UpdateMode {
    // --update=`all`,
    ReplaceAll,
    // --update=`none`
    ReplaceNone,
    // --update=`older`
    // -u
    ReplaceIfOlder,
}
```
namely `ReplaceNone`, which I have not added. Also I think that
specifying `--update 'abc'` is non functional.

redirect should have a target (#10835)

Fixes:  #10830 

The issue happened during lite-parsing, when we want to put a

ignore`.

This pr is going to check and return an error if redirection target is
empty.

fix: Ensure consistent vals and cols when parsing with --flexible (#10814)
# Description
`from tsv` and `from csv` both support a `--flexible` flag. This flag
can be used to "allow the number of fields in records to be variable".

Previously, a record's invariant that `rec.cols.len() == rec.vals.len()`
could be broken during parsing. This can cause runtime errors as in
#10693. Other commands, like `select` were also affected.

The inconsistencies are somewhat hard to see, as most nushell code
assumes an equal number of columns and values.

# Before

### Fewer values than columns
```nushell
> let record = (echo "one,two\n1" | from csv --flexible | first)
# There are two columns
> $record | columns | to nuon
[one, two]
# But only one value
> $record | values | to nuon
[1]
# And printing the record doesn't show the second column!
> $record | to nuon
{one: 1}
```

### More values than columns
```nushell
> let record = (echo "one,two\n1,2,3" | from csv --flexible | first)
# There are two columns
> $record | columns | to nuon
[one, two]
# But three values
> $record | values | to nuon
[1, 2, 3]
# And printing the record doesn't show the third value!
> $record | to nuon
{one: 1, two: 2}
```
# After

### Fewer values than columns
```nushell
> let record = (echo "one,two\n1" | from csv --flexible | first)
# There are two columns
> $record | columns | to nuon
[one, two]
# And a matching number of values
> $record | values | to nuon
[1, null]
# And printing the record works as expected
> $record | to nuon
{one: 1, two: null}
```

### More values than columns
```nushell
> let record = (echo "one,two\n1,2,3" | from csv --flexible | first)
# There are two columns
> $record | columns | to nuon
[one, two]
# And a matching number of values
> $record | values | to nuon
[1, 2]
# And printing the record works as expected
> $record | to nuon
{one: 1, two: 2}
```

# User-Facing Changes
Using the `--flexible` flag with `from csv` and `from tsv` will not
result in corrupted record state.

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*

> 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/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.

rename nushell's cp command to cp-old making coreutils the default cp (#10678)
# Description

This PR renames nushell's `cp` command to `cp-old` to make room for
`ucp` to be renamed to `cp`, making the coreutils version of `cp` the
default for nushell. After some period of time, we should remove
`cp-old` entirely.

fix clippy (#10659)
This pr fix clippy warnings in latest clippy version(1.72.0):

Unfortunally it's not easy to handle for [try
fold](https://rust-lang.github.io/rust-clippy/master/index.html#/manual_try_fold)
warning in `start command`

Refer to known issue:
> This lint doesn’t take into account whether a function does something
on the failure case, i.e., whether short-circuiting will affect
behavior. Refactoring to try_fold is not desirable in those cases.

That's the case for our code, which does something on the failure case.

So this pr is making a little refactor on `try_commands`.

ucp: Change error when directory is specified but not recursive (#10609)
# Description
Closes #10537. Basically error message was unhelpful, and this temporary
measure adds back the nice previous nushell error message. Ideally, we
would like to add a more permanent solution mentioned in the issue
[comments](https://github.com/nushell/nushell/issues/10537#issuecomment-1743686122),
but since we want to have `ucp` as `cp` on new release, this is hackier
but way simpler so this fix should do it.

Only downside is that now behavior differs from `uutils` in the sense
that:
```
uutils:
> cp a foo/ bar
ls bar
# foo/a

nushell:
>ucp a foo/ bar
# directory error (not copied) ....
```
So, since its non fatal error, uutils copies a, but nushell errors out
with nothing copied. If we go to option 3 mentioned above, then we can
decide what we want to do, and perhaps continue on a non fatal error.

Add url decode command (#10611)
Implemented URL decoding as a url subcommand, created corresponding unit
tests. The logic, examples and descriptions were based on the existing
`url encode` command.

Resolves #10563

# Description
Added a new `url decode` command to compliment the existing `url

Use int type name consistently (#10579)
# Description
When referring to the type use `int` consistently. Only when referring
to the concept of integer numbers use `integer`.

- Fix `random integer` to `random int` tests
  - Forgot in #10520
- Use int instead of integer in error messages
- Use int type name in bits commands
- Fix messages in `for` examples
- Use int typename in `into` commands
- Use int typename in rest of commands
- Report errors in `nu-protocol` with int typename

Work for #10332 

# User-Facing Changes

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:

-->
> [!NOTE]
> This PR description originally used examples where the `generator`
closure returned a list. It has since been updated to use records
instead.

The `unfold` command allows users to dynamically generate streams of
data. The stream is generated by repeatedly invoking a `generator`
closure. The `generator` closure accepts a single argument and returns a
record containing two optional keys: 'out' and 'next'. Each invocation,
the 'out' value, if present, is added to the stream. If a 'next' key is
present, it is used as the next argument to the closure, otherwise
generation stops.

The name "unfold" is borrowed from other functional-programming
languages. Whereas `fold` (or `reduce`) takes a stream of values and
outputs a single value, `unfold` takes a single value and outputs a
stream of values.

### Examples

A common example of using `unfold` is to generate a fibbonacci sequence.
See
[here](6ffdac103c/src/sources.rs (L65))
for an example of this in rust's `itertools`.

```nushell
> unfold [0, 1] {|fib| {out: $fib.0, next: [$fib.1, ($fib.0 + $fib.1)]} } | first 10
───┬────
 0 │  0
 1 │  1
 2 │  1
 3 │  2
 4 │  3
 5 │  5
 6 │  8
 7 │ 13
 8 │ 21
 9 │ 34
───┴────
```

This command is particularly useful when consuming paginated APIs, like
Github's. Previously, nushell users might use a loop and buffer
responses into a list, before returning all responses at once. However,
this behavior is not desirable if the result result is very large. Using
`unfold` avoids buffering and allows subsequent pipeline stages to use
the data concurrently, as it's being fetched.

#### Before
```nushell
mut pages = []
for page in 1.. {
  let resp = http get (
    {
      scheme: https,
      host: "api.github.com",
      path: "/repos/nushell/nushell/issues",
      params: {
	page: $page,
	per_page: $PAGE_SIZE
      }
    } | url join)

  $pages = ($pages | append $resp)

  if ($resp | length) < $PAGE_SIZE {
    break
  }
}
$pages
```

#### After
```nu
unfold 1 {|page|
  let resp = http get (
    {
      scheme: https,
      host: "api.github.com",
      path: "/repos/nushell/nushell/issues",
      params: {
	page: $page,
	per_page: $PAGE_SIZE
      }
    } | url join)

  if ($resp | length) < $PAGE_SIZE {
    {out: $resp}
  } else {
    {out: $resp, next: ($page + 1)}
  }
}
```

Making open case-insensitive to file extensions (#10451)
# Description

Closes #10441 

Uses `String::to_lowercase()` when the file's extension `ext` is parsed
to allow `from_decl(format!("from {ext}"))` to return the desired output
regardless of extension case.

It doesn't work with sqlite files since those are handled earlier in the
parsing but I think is good- since there's no standard file extension
used by sqlite so a user will likely want case sensitivity in that case.

This also has the (possibly undesired) effect of making `open`
completely case insensitive, e.g. `open foo.JSON` will work on a file
named `foo.json` and vice versa. This is good on Windows as it treats
`foo.json` and `foo.JSON` as the same file, but may not be the desired
behaviour on Unix.

If this behaviour is undesired I assume it would be fixed with a
`#[cfg(not(unix))]` attribute on the `to_lowercase()` operation but that
produces slightly "uglier" code that I didn't wish to submit unless
necessary. 

old behaviour:

![image](https://github.com/nushell/nushell/assets/79598494/261df577-e377-44ac-bef3-f6384bceaeb5)

# User-Facing Changes

`open` will now present a table when `open`-ing files with captitalized
extensions rather than the file's raw data

glob with ../ prefix now works; (#10504)
Fixes #10503 
Also improves link to metacharacter help;

# Description
`glob` code was using pattern as provided by user. If that had leading
`..\`, `wax::Glob` is documented to treat them as literal chars to be
matched.
Fix is to use `wax::Glob.partition()` to split such invariant prefixes
off the pattern and tack them onto the working directory computed
separately.

remove the $nothing variable (#10478)
related to 
- https://github.com/nushell/nushell/pull/9973
- 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 👍

Closes #5436

When I opened this issue more than a year ago, I mainly wanted the
following capacity: easily access the full env and have the hability to
update it when a new version of `nushell` comes out.

With this PR I can now do the following:

```nu
source-env ~/.config/nushell/defaults/env.nu
source     ~/.config/nushell/defaults/config.nu

# Update nushell default config & env file (run this after a version update)
def update-defaults [] {
    config env --default | save -f ~/.config/nushell/defaults/env.nu
    config nu  --default | save -f ~/.config/nushell/defaults/config.nu
}
```

Which is more than enough for me. Along with `nushell` respecting the
XDG spec on macOS (`dirs-next` should be banned for CLI tools on macOS),
this should be one of the last hurdle before fully switching for me!

differentiating between --x and --x: bool (#10456)
# Description
Fixes: #10450 

This pr differentiating between `--x: bool` and `--x`

Here are examples which demostrate difference between them:
```nushell
def a [--x: bool] { $x };
a --x    # not allowed, you need to parse a value to the flag.
a        # it's allowed, and the value of `$x` is false, which behaves the same to `def a [--x] { $x }; a`
```

For boolean flag with default value, it works a little bit different to
#10450 mentioned:
```nushell
def foo [--option: bool = false] { $option }
foo                  # output false
foo --option         # not allowed, you need to parse a value to the flag.
foo --option true    # output true
```

# User-Facing Changes
After the pr, the following code is not allowed:
```nushell
def a [--x: bool] { $x }; a --x
```

Instead, you have to pass a value to flag `--x` like `a --x false`. But
bare flag works in the same way as before.

## Update: one more breaking change to help on #7260 
```
def foo [--option: bool] { $option == null }
foo
```
After the pr, if we don't use a boolean flag, the value will be `null`
instead of `true`. Because here `--option: bool` is treated as a flag
rather than a switch

don't overrite arg's type if it's annotated explicitly (#10424)
# Description
Fixes: #10410 

So the following script is possible:
```nushell
def a [b: any = null] { let b = ($b | default "default_b"); }
a "given_b"
```

## About the change
When parsing signature, and nushell meets something like `a: any`, it
force the parser to treat `a` as `any` type. This is what
`arg_explicit_type` means, it's only set when we goes into
`ParseMode::TypeMode`, and it will be reset to `false` if the token goes
to next argument.

so, when we have something like this: `def a [b: any = null] { $b }`,
the type of `$b` won't be overwritten.

But if we have something like this: `def a [b = null] { $b }`, the type
of `$b` is not annotated, so we make it to be `nothing`(which is the
type of null)

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.

Change echo to print when not redirected (#10338)
# Description

This changes `echo` to work more closely to what users of other shells
would expect:

* when redirected, `echo` works as before and sends values through the
pipeline
* when not redirected, `echo` will print values to the screen/terminal

# User-Facing Changes

A standalone `echo` now will print to the terminal, if not redirected.

The `echo` command is no longer const eval-able, as it will now print to
the terminal in some cases.

Also added the test to ensure its working:) . Oh, and I tweaked again
slightly the messages on two tests because now the whole `path` is
printed rather than `a`. Say:
```
#before
`cp a a` --> 'a' and 'a' are the same file 
# now
`cp a a` --> /home/current/location/a and /home/current/location/a are the same file

# User-Facing Changes
users can now `reject` multiple rows independently of each other.
```nushell
let foo = [[a b]; [ 1 2] [3 4] [ 5 6]]
# this will work independant of the order
print ($foo | reject 2 1)
print ($foo | reject 1 2)
```

# Description
Hi. Basically, this is a continuation of the work that @fdncred started.
Given some nice discussions on #9463 , and [merged uutils
PR](https://github.com/uutils/coreutils/pull/5152) from @tertsdiepraam
we have decided to give the `cp` command the `crawl` stage as it was
named.

> [!NOTE] 
Given that the `uutils` crate has not made the release for the merged
PR, just make sure you checkout latest and put it in the required place
to make this PR work.

The aim of this PR is for is to see how to move forward using `uutils`
crate. In order to getting this started, I have made the current
`nushell cp tests` pass along with some extra ones I copied over from
the `uutils` repo.

With all of that being said, things that would be nice to decide, and
keep working on:

Crawl:
- Handling of certain `named` flags, with their long and short
forms(e.g. --update, --reflink, --preserve, etc), and using default
values. Maybe `-u` can already have a `default_missing_value`.
- Should we maybe just support one single option `switch` flags (see
`--backup` in code) as a contrast to the other named args.
- Complete test coverage from `uutils`. They had > 100 tests, and I
could only port like 12 as they are a bit time consuming given they
cannot be straight up copy pasted. Maybe we do not need all >100, but
maybe the more relevant to what we want.
- Refactor this code

Walk:
- Non fatal errors on `copy` from `utils`. Currently it just sends it to
stdout but errors have no span
- Better integration 

An added possibility is the addition of `SyntaxShape::OneOf()` for
`Named` arguments which was briefly mentioned in the discord server, but
that is still to be decided. This could greatly improve some of the
integration. This would enable something like `cp --preserve [all
timestamp]` or `cp --preserve all` to both work.

I did not want to keep holding on this, and wait till I was happy with
the code because I think its nice if everyone can start up and suggest
refactors, but the main important part now was getting it out the door,
as if I take my sweet time this will take way longer 😛

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.

treat path contains '?' as pattern (#10142)
Fix https://github.com/nushell/nushell/issues/10136

# Description
Current nushell only handle path containing '*' as match pattern and
treat '?' as just normal path.
This pr makes path containing '?' is also processed as pattern.

🔴 **Concerns: Need to design/comfirm a consistent rule to handle
dirs/files with '?' in their names.**

Currently:

- if no dir has exactly same name with pattern, it will print the list
of matched directories
- if pattern exactly matches an empty dir's name, it will just print the
empty dir's content ( i.e. `[]`)
- if pattern exactly matches an dir's name, it will perform pattern
match and print all the dir contains

e.g.
```bash
mkdir src
ls s?c 
```

| name | type | size   | modified                                      |
| ---- | ---- | ------ | --------------------------------------------- |
| src  | dir  | 1.1 KB | Tue, 29 Aug 2023 07:39:41 +0900 (9 hours ago) |

-----------

```bash
mkdir src
mkdir scc
mkdir scs
ls s?c
```

| name | type | size | modified |
| ---- | ---- | ------ |
------------------------------------------------ |
| scc | dir | 64 B | Tue, 29 Aug 2023 16:55:31 +0900 (14 seconds ago) |
| src | dir | 1.1 KB | Tue, 29 Aug 2023 07:39:41 +0900 (9 hours ago) |

-----------

```bash
mkdir  s?c
ls s?c
```

print empty (i.e. ls of dir `s?c`)

-----------

```bash
mkdir -p  s?c/test
ls s?c
```
|name|type|size|modified|
|-|-|-|-|
|s?c/test|dir|64 B|Tue, 29 Aug 2023 16:47:53 +0900 (2 minutes ago)|

Simplify rawstrings in tests (#10180)
Inspired by

https://github.com/rust-lang/rust-clippy/issues/11068

Also collapse one set of single line tests.

Remove dead tests depending on inc (#10179)
They relied on the `nu_plugin_inc` but where behind a feature flag that
isn't actually defined anywhere. These tests of `update` or `upsert`
shouldn't really depend on `inc` so I decided to remove them outright as
they haven't been used to exercise the commands under test.

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.

remove --column from length command and remove record processing (#10091)
# Description

This PR removes `record` processing from the `length` command. It just
doesn't make sense to try and get the length of a record. This PR also
removes the `--column` parameter. If you want to list or count columns,
you could use `$table | columns` or `$table | columns | length`.

Make http -f display the request headers. Closes #9912 (#10022)
# Description
As described in https://github.com/nushell/nushell/issues/9912, the
`http` command could display the request headers with the `--full` flag,
which could help in debugging the requests. This PR adds such
functionality.

# User-Facing Changes
If `http get` or other `http` command which supports the `--full` flag
is invoked with the flag, it used to display the `headers` key which
contained an table of response headers. Now this key contains two nested
keys: `response` and `request`, each of them being a table of the
response and request headers accordingly.

Rename misused "deprecation" to removal (#10000)
# Description
In the past we named the process of completely removing a command and
providing a basic error message pointing to the new alternative
"deprecation".

But this doesn't match the expectation of most users that have seen
deprecation _warnings_ that alert to either impending removal or
discouraged use after a stability promise.

-->

# Description
This PR implements the workaround discussed in #9795, i.e. having
`parse` collect an external stream before operating on it with a regex.

- Should close #9795 

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

- `parse` will give the correct output for external streams
- increased memory and time overhead due to collecting the entire stream
(no short-circuiting)

Currently `parse` acts like a `.filter` over an iterator, except that it
emits `None` for elements that can't be parsed. This causes consumers of
the adapted iterator to stop iterating too early. The correct behaviour
is to keep pulling the inner iterator until either the end of it is
reached or an element can be parsed.

- this PR should close #9906

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.

rename from date format to format date (#9902)
# Description
Closes: #9891
I also think it's good to keep command name consistency.

And moving `date format` to deprecated.

# User-Facing Changes
Running `date format` will lead to deprecate message:
```nushell

Accept records for http subcommand headers (-H) (#9771)
# Description

See also: #9743 
Before: 
`http <subcommand> -H` took a list in the form:

```nushell
[my-header-key-A my-header-value-A my-header-key-B my-header-value-B]
```

Now:
In addition to the old format, Records can be passed, For example,
```nushell
> let reqHeaders = {
    Cookie:  "acc=barfoo",
    User-Agent: "Mozilla/7.0 (Windows NT 33.0; Win64; x64) AppleWebKit/1038.90 (KHTML, like Gecko)"
}
> http get -H $reqHeaders https://example.com
```

is now equivalent to
```nushell
http get -H [Cookie "acc=barfoo" User-Agent "Mozilla/7.0 (Windows NT 33.0; Win64; x64) AppleWebKit/1038.90 (KHTML, like Gecko)"] https://example.com
```

# User-Facing Changes
No breaking changes, but Records can now also be passed to `http
<subcommand> -H`.

Fix signature of split row (#9829)
# Description
This command also flat-maps and doesn't create a table like `split

We should probably reconsider the flatmap behavior like in #9739
but for the #9812 hotfix this is an unwelcome breaking change.

# User-Facing Changes
None

add input_output_type to ansi command (#9817)
# Description

This PR fixes this not working `ansi --list | columns`. I originally
thought that this was a problem with `columns` but it turned out to be a
problem with the input output type of `ansi`. Since `ansi` was only
allowed to return strings, `columns` thought it was getting a string,
but it was a table.

closes #9808

```
Parameters:
  ...rest <cellpath>: for a data structure input, convert data at the given cell paths
```
it looks like `into datetime` should accept tables as input 🤔

- adds the `table -> table` signature to `into datetime`
- adds a test to make sure the behaviour stays there

that use the `nu!` macro.

change the output of which to be more explicit (#9646)
related to
- https://github.com/nushell/nushell/issues/9637#issuecomment-1629387548

# Description
this PR changes the output of `which` from `table<arg: string, path:
string, built-in: bool> (stream)` to `table<command: string, path:
string, type: string> (stream)`.
- `command`: same as `arg` but more explicit name
- `path`: same as before, `null` when built-in
- `type`: instead of `buil-in: bool` says if it's a `built-in` a
`custom` command, an `alias` or an `external`

# User-Facing Changes

Support variables/interpolation in o>, e>, o+e> redirect (#9747)
# Description
Fixes:  #8517
Fixes: #9246
Fixes: #9709
Relative: #9723


## About the change
Before the pr, nushell only parse redirection target as a string(through
`parse_string` call).
In the pr, I'm trying to make the value more generic(using `parse_value`
with `SyntaxShape::Any`)

And during eval stage, we guard it to only eval `String`,
`StringInterpolation`, `FullCellPath`, `FilePath`, so other type of
redirection target like `1ms` won't be permitted.

# User-Facing Changes

After the pr: redirection support something like the following:
1. `let a = "x"; cat toolkit.nu o> $a`
2. `let a = "x"; cat toolkit.nu o> $"($a).txt"`
3. `cat toolkit.nu out> ("~/a.txt" | path expand)`

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`

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

# 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

Custom command input/output types (#9690)
# Description

This adds input/output types to custom commands. These are input/output
pairs that related an input type to an output type.

For example (a single int-to-int input/output pair):

```
def foo []: int -> int { ... }
```

You can also have multiple input/output pairs:
```
def bar []: [int -> string, string -> list<string>] { ... }
```

These types are checked during definition time in the parser. If the
block does not match the type, the user will get a parser error.

This `:` to begin the input/output signatures should immediately follow
the argument signature as shown above.

The PR also improves type parsing by re-using the shape parser. The
shape parser is now the canonical way to parse types/shapes in user
code.

This PR also splits `extern` into `extern`/`extern-wrapped` because of
the parser limitation that a multi-span argument (which Signature now
is) can't precede an optional argument. `extern-wrapped` now takes the
required block that was previously optional.

# User-Facing Changes

The change to `extern` to split into `extern` and `extern-wrapped` is a
breaking change.

Input output checking (#9680)
# Description

This PR tights input/output type-checking a bit more. There are a lot of
commands that don't have correct input/output types, so part of the
effort is updating them.

This PR now contains updates to commands that had wrong input/output
signatures. It doesn't add examples for these new signatures, but that
can be follow-up work.

# User-Facing Changes

BREAKING CHANGE BREAKING CHANGE

This work enforces many more checks on pipeline type correctness than
previous nushell versions. This strictness may uncover incompatibilities
in existing scripts or shortcomings in the type information for internal
commands.

So we can do the following in nushell:
```nushell
mut a = 3
$a = if 4 == 3 { 10 } else {20}
```
or
```nushell
$env.BUILD_EXT = match 3 { 1 => { 'yes!' }, _ => { 'no!' } }
```
