# Description
This makes the help messages cleaner for keyword-style arguments.
Before:
```
(optional) else_expression <Keyword([101, 108, 115, 101], Expression)>: expression or block to run if check fails
```
Now:
```
(optional) "else" + <expression>: expression or block to run if check fails
```

# Description
This adds `break`, `continue`, `return`, and `loop`.
* `break` - breaks out a loop
* `continue` - continues a loop at the next iteration
* `return` - early return from a function call
* `loop` - loop forever (until the loop hits a break)
Examples:
```
for i in 1..10 {
if $i == 5 {
continue
}
print $i
}
```
```
for i in 1..10 {
if $i == 5 {
break
}
print $i
}
```
```
def foo [x] {
if true {
return 2
}
$x
}
foo 100
```
```
loop { print "hello, forever" }
```
```
[1, 2, 3, 4, 5] | each {|x|
if $x > 3 { break }
$x
}
```

A small follow-up to #7221. This changes the `catch` block from a block
to a closure, so that it can access the error returned from the `try`
block. This helps with a common scenario: "the `try` block failed, and I
want to log why it failed."
### Example
### Future Work
Nu's closure syntax is a little awkward here; it might be nicer to allow
something like `catch err { print $err }`. We discussed this on Discord
and it will require special parser code similar to what's already done
for `for`.
I'm not feeling confident enough in my parser knowledge to make that
change; I will spend some more time looking at the `for` code but I
doubt I will be able to implement anything in the next few days.
Volunteers welcome.
# Description
This adds `try` (with an optional `catch` piece). Much like other
languages, `try` will try to run a block. If the block fails to run
successfully, the optional `catch` block will run if it is available.
# User-Facing Changes
This adds the `try` command.

# Description
`uniq -i` does not convert output strings to lowercase.
Also, `uniq -i` did not ignore case in strings below the first level of
Tables and Records. Now all strings case are ignored for all children
Values for tables, Records, and List.
Fixes https://github.com/nushell/nushell/issues/7192
# Tests + Formatting
About the issue https://github.com/nushell/nushell/issues/7192, the
output will be:
```
〉[AAA BBB CCC] | uniq -i
╭───┬─────╮
│ 0 │ AAA │
│ 1 │ BBB │
│ 2 │ CCC │
╰───┴─────╯
```
About ignoring case for all children string, I expect this to be true:
```
([[origin, people];
[World, (
[[name, meal];
['Geremias', {plate: 'bitoque', carbs: 100}]
]
)],
[World, (
[[name, meal];
['Martin', {plate: 'bitoque', carbs: 100}]
]
)],
[World, (
[[name, meal];
['Geremias', {plate: 'Bitoque', carbs: 100}]
]
)],
] | uniq -i
) == ([[origin, people];
[World, (
[[name, meal];
['Geremias', {plate: 'bitoque', carbs: 100}]
]
)],
[World, (
[[name, meal];
['Martin', {plate: 'bitoque', carbs: 100}]
]
)]
])
```
# Description
While trying to add a new `uniq-by` command I refactored the `uniq`
command code to understand it and try to reuse. I think this is more
compact and easier to understand.
The part that I think it's a little confusing in this refactor is the
conditions inside `.filters()`, for example: `!flag_show_repeated ||
(value.1 > 1)`. I could use `if (flag_show_repeated) {value.1 > 1} else
{true}` but it is more verbose, what do you think?
PS: Not sure if you like this kind of PR, sorry if not.
# Tests + Formatting
I also added a test where the `uniq` has a table as input.
Fixes a two's complement underflow/overflow when given a negative arg.
Breaking change as it is throwing an error instead of most likely
returning most of the output.
Same behavior as #7184

Following up on #7180 with some feature cleanup:
- Move the `database` feature from `plugin` to `default`
- Rename the `database` feature to `sqlite`
- Remove `--features=extra` from a lot of scripts etc.
- No need to specify this, the `extra` feature is now the same as the
default feature set
- Remove the now-redundant 2nd Ubuntu test run
This adds new pipeline connectors called out> and err> which redirect either stdout or stderr to a file. You can also use out+err> (or err+out>) to redirect both streams into a file.
Alters `all`, `any`, `each while`, `each`, `insert`, `par-each`, `reduce`, `update`, `upsert` and `where`,
so that their blocks take an optional parameter containing the index.

This adds support for (limited) mutable variables. Mutable variables are created with mut much the same way immutable variables are made with let.
Mutable variables allow mutation via the assignment operator (=).
❯ mut x = 100
❯ $x = 200
❯ print $x
200
Mutable variables are limited in that they're only tended to be used in the local code block. Trying to capture a local variable will result in an error:
❯ mut x = 123; {|| $x }
Error: nu::parser::expected_keyword (link)
× Capture of mutable variable.
The intent of this limitation is to reduce some of the issues with mutable variables in general: namely they make code that's harder to reason about. By reducing the scope that a mutable variable can be used it, we can help create local reasoning about them.
Mutation can occur with fields as well, as in this case:
❯ mut y = {abc: 123}
❯ $y.abc = 456
❯ $y
On a historical note: mutable variables are something that we resisted for quite a long time, leaning as much as we could on the functional style of pipelines and dataflow. That said, we've watched folks struggle to work with reduce as an approximation for patterns that would be trivial to express with local mutation. With that in mind, we're leaning towards the happy path.

* fix: ✨ "saner" default for mv
fixes#6747
As highlighted in the issue, the default behavior of nu currently
is to overwrite the destination file without notice.
This is not a "standard" expectation users that want this behavior
can create a dedicated alias.
* fix: 📝 edit the comment
* fix: ✨ updated the tests
* fix: 🚧 use --force for case test
* Remove unnecessary `#[allow]` annots
Reduce the number of lint exceptions that are not necessary with the
current state of the code (or more recent toolchain)
* Remove dead code from `FileStructure` in nu-command
* Replace `allow(unused)` with relevant feature switch
* Deal with `needless_collect` with annotations
* Change hack for needless_collect in `from json`
This change obviates the need for `allow(needless_collect)`
Removes a pessimistic allocation for empty strings, but increases
allocation size to `Value`
Probably not really worth it.
* Revert "Deal with `needless_collect` with annotations"
This reverts commit 05aca98445.
The previous state seems to better from a performance perspective as a
`Vec<String>` is lighter weight than `Vec<Value>`
* Filter out empty glob patterns
An empty argument to the "glob" command will now produce an empty result.
Working towards nushell/nushell#6653.
* Run `cargo fmt --all`
Just autoformatted the repo so that CI passes and we have a consistent code
format across modules.
* Treat empty glob argument as error
The glob command will now report an empty string argument as an error instead
of silently ignoring it.
See https://github.com/nushell/nushell/pull/6707#discussion_r993345013.
* Add tests for glob command
Two small tests for the glob command, one to check that the empty string errors
it, and another to sanity check the '*' glob, have been added.
* Rename glob sanity check star test

Rename `all?`, `any?` and `empty?` to `all`, `any` and `is-empty` for sake of simplicity and consistency.
- More understandable for newcomers, that these commands are no special to others.
- `?` syntax did not really aprove readability. For me it made it worse.
- We can reserve `?` syntax for any other nushell feature.

* Move `get_system_locale()` to `locale` module
* Allow overriding locale with special env variable (when not in release)
* Use special env var to override locale during testing
* Allow callback to return a value in `with_locale_override()`
* Allow multiple options in `nu!` macro
* Allow to set locale as `nu!` macro option
* Use new `locale` option of `nu!` macro instead of `with_locale_override`
Using the `locale` options does not lock the `LOCALE_OVERRIDE_MUTEX`
mutex in `nu-test-support::locale_override` but instead calls the `nu`
command directly with the `NU_LOCALE_OVERRIDE` environment variable.
This allows for parallel test excecution.
* Fix: Add option identifier for `cwd` in usage of `nu!` macro

This commit
- Adds `encode` command family
- Backports `hash base64` features to `encode base64` and `decode base64` subcommands.
- Refactors code a bit and extends tests for encodings
- `decode base64` returns a binary `Value` (that may be decoded into a string using `decode` command)
* feat: add `--binary(-b)` flag to `decode base64`
Default output type is now string, but binary can be requested using this new flag.
