# 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.
* add signature information when help on one command

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

`nu_protocol::ShellError::DeprecatedCommand` since a prominent project
uses the API:
b85542c31c/src/virtualenv/activation/nushell/activate.nu (L43)
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.

* 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.

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)

* Remove panic from BlockCommands run function
Instead of panicing, the run method now returns an error to prevent
nushell from unexpected termination.
* Add ability to open command to run with blocks
The open command tries to parse the content of the file
if there is a command called 'from (file ending)'. This works
fine if the command was 'built in' because the run method doesn't
fail in this case. It did fail on a BlockCommand, though.
This change will first probe if the command contains a block and
evaluate it, if this is the case. If there is no block, it will run
the command the same way as before.
* Add test open files with BlockCommands
* Update open.rs
* Adjust file type on open with BlockCommand parser

* Add streaming support to save for ExternalStream data
Prior to this change, save would collect data from an ExternalStream (data
originating from externals) consuming memory for the full amount of data piped
to it,
This change adds streaming support for ExternalStream allowing saving of
arbitrarily large files and bounding memory usage.
* Remove broken save test
This test passes but not for the right reasons, since this test was
written filename has become a required parameter. The parser outputs
an error but the test still passes as is checking the original un-mutated
file assuming save has re-written the contents.
This change removes the test.

* Fix typo
* Add subcommand `into filesize`
It's currently not possible to convert a number or a string containing a number
into a filesize. The only way to create an instance of filesize type today is
with a literal in nushell syntax. This commit adds the `into filesize`
subcommand so that file sizes can be created from the outputs of programs
producing numbers or strings, like standard unix tools.
There is a limitation with this - it doesn't currently parse values like `10 MB`
or `10 MiB`, it can only look at the number itself. If the desire is there, more
flexible parsing can be added.
* fixup! Add subcommand `into filesize`
* fixup! Add subcommand `into filesize`
* Allow environment variables to be hidden
This change allows environment variables in Nushell to have a value of
`Nothing`, which can be set by the user by passing `$nothing` to
`let-env` and friends.
Environment variables with a value of Nothing behave as if they are not
set at all. This allows a user to shadow the value of an environment
variable in a parent scope, effectively removing it from their current
scope. This was not possible before, because a scope can not affect its
parent scopes.
This is a workaround for issues like #3920.
Additionally, this allows a user to simultaneously set, change and
remove multiple environment variables via `load-env`. Any environment
variables set to $nothing will be hidden and thus act as if they are
removed. This simplifies working with virtual environments, which rely
on setting multiple environment variables, including PATH, to specific
values, and remove/change them on deactivation.
One surprising behavior is that an environment variable set to $nothing
will act as if it is not set when querying it (via $nu.env.X), but it is
still possible to remove it entirely via `unlet-env`. If the same
environment variable is present in the parent scope, the value in the
parent scope will be visible to the user. This might be surprising
behavior to users who are not familiar with the implementation details.
An additional corner case is the the shorthand form of `with-env` does
not work with this feature. Using `X=$nothing` will set $nu.env.X to the
string "$nothing". The long-form works as expected: `with-env [X
$nothing] {...}`.
* Remove unused import
* Allow all primitives to be convert to strings
Given we can write nu scripts. As the codebase grows, splitting into many smaller nu scripts is necessary.
In general, when we work with paths and files we seem to face quite a few difficulties. Here we just tackle one of them and it involves sourcing
files that also source other nu files and so forth. The current working directory becomes important here and being on a different directory
when sourcing scripts will not work. Mostly because we expand the path on the current working directory and parse the files when a source command
call is done.
For the moment, we introduce a `lib_dirs` configuration value and, unfortunately, introduce a new dependency in `nu-parser` (`nu-data`) to get
a handle of the configuration file to retrieve it. This should give clues and ideas as the new parser engine continues (introduce a way to also know paths)
With this PR we can do the following:
Let's assume we want to write a nu library called `my_library`. We will have the code in a directory called `project`: The file structure will looks like this:
```
project/my_library.nu
project/my_library/hello.nu
project/my_library/name.nu
```
This "pattern" works well, that is, when creating a library have a directory named `my_library` and next to it a `my_library.nu` file. Filling them like this:
```
source my_library/hello.nu
source my_library/name.nu
```
```
def hello [] {
"hello world"
}
```
```
def name [] {
"Nu"
end
```
Assuming this `project` directory is stored at `/path/to/lib/project`, we can do:
```
config set lib_dirs ['path/to/lib/project']
```
Given we have this `lib_dirs` configuration value, we can be anywhere while using Nu and do the following:
```
source my_library.nu
echo (hello) (name)
```
* Allow sourcing paths with emojis
* Add source command tests for emoji paths

We introduce it here and allow it to work with regular lists (tables with no columns) as well as symmetric tables. Say we have two lists and wish to zip them, like so:
```
[0 2 4 6 8] | zip {
[1 3 5 7 9]
} | flatten
───┬───
0 │ 0
1 │ 1
2 │ 2
3 │ 3
4 │ 4
5 │ 5
6 │ 6
7 │ 7
8 │ 8
9 │ 9
───┴───
```
In the case for two tables instead:
```
[[symbol]; ['('] ['['] ['{']] | zip {
[[symbol]; [')'] [']'] ['}']]
} | each {
get symbol | $'($in.0)nushell($in.1)'
}
───┬───────────
0 │ (nushell)
1 │ [nushell]
2 │ {nushell}
───┴───────────
```

Using the `*` wildcard should not attempt to delete files with a leading dot
unless the more explicit `.*` is used. `rm *` should also not attempt to delete
the current directory or its parent directory (`.` and `..`). I have resolved
this bug as well in a less satisfactory way. I think it may be the case that we
can only disambiguate the `.` and `..` path segments by using `Path::display`.
Here is a short list of alternatives that I tried:
- `Path::ends_with()` can detect `/..` but not `/.`.
- `Path::iter()` and `Path::components()` leave out `/.`.
- `Path::file_name()` normalizes `/.` to the parent component's file name.
Fixes#3508
* commands to engine
* Correction of error in parser
* Added detailed regex error to parse
* better regex error parsing
* clippy corrections
* parse example with test
* secondary error for regex
* removed clone in error parser
* Secondary error message
* Add new path parse subcommand
This includes a slight refactor to all the path subcommand `action()`
functions.
* Remove filestem and extension; Fix example
* Add additional description to path parse
* Put join arg behind flag; Fix missing import (Win)
* Fix error when column path is passed as arg
* Add structured path joining
Structured path is implicitly joined at every patch subcommand call.
* Fix existing path join tests; Fix rustfmt
* Remove redundant 'static lifetime (clippy)
* Add initial impl of path split subcommand
* Add ability to join path from parts
* Fix wrong results in path split examples
* Fix remaining asyncs after engine change
* Do not wrap split path parts into table
When the input is just a list of values, the `path split` command will
split each value directly into the output stream, similar to
`split-row`. Column path--specified values are still wrapped into a
table so they can still be used to replace table fields.
* Join list of values instead of going one-by-one
When `path join` encounters a list of values, it attempts to join them,
instead of going one-by-one like the rest of the path commands. You can
still `each { echo $it | path join }` to join them one-by-one, if the
values are, e.g., tables.
Now, the behavior of `path split` and `path join` should match the
`split-row` and `str collect` counterparts and should hopefully align
better with user's expectations.
* Make sure path join detects structured path
* Fix panic on empty input stream
Also, doesn't collect input into vector unnecessarily.
* Fix path join not appending value
* Remove argument serialization
* Make better errors; Misc refactor
* OsStr -> String encoding is now lossy, instead of throwing an error
* The consequence is action() now always returns Value instead of Result
* Removed redundant handle_value() call in `path join`
* Fix possible incorrect error detection in `path split`
* Applied rustfmt + clippy
* Add more usage, examples & test; Fix type error
The 'parent' column was required to be a path but didn't work with
string.
* Add more help & examples; Maybe fix Windows error
* Refactor operate function
Reducing code repetition
* Review usages and examples
* Add the option to manually specify the extension
* Add more tests; Fix failures on Windows
* Move path commands to engine-p
* Small refactor
* Use ctx.configs in all config commands
* Remove all setting/accessing of vars.("config-path")
* Add tests
* Add comment
* Reload cfg on remove
* Hypocratic ws change
* Use history_path in hist_or_default
* Make clippy happy
* Fix rebase stuff
* Fix clippy lint
* commands: any? all?
We can check if `any` (or `all`) rows of tables match predicates.
Small `all?` example: Given the following table with `services` running:
```
> echo [[status]; [UP] [UP]]
───┬────────
# │ status
───┼────────
0 │ UP
1 │ UP
───┴────────
```
We can ask if all services are UP, like so:
```
> echo [[status]; [UP] [UP]] | all? status == UP
true
```

* Playground infraestructure (tests, etc) additions.
A few things to note:
* Nu can be started with a custom configuration file (`nu --config-file /path/to/sample_config.toml`). Useful for mocking the configuration on test runs.
* When given a custom configuration file Nu will save any changes to the file supplied appropiately.
* The `$nu.config-path` variable either shows the default configuration file (or the custom one, if given)
* We can now run end to end tests with finer grained control (currently, since this is baseline work, standard out) This will allow to check things like exit status, assert the contents with a format, etc)
* Remove (for another PR)
* Make opening a directory enter it.
Not sure if this change is wanted, but I'm not sure what else opening a directory could mean.
And I find myself accidentally using `open <dir>` to mean `enter <dir>`
* Add example to open directory
* Open dir should list it's contents
* Update example description and fix style
* update docs to refer to length instead of count
* rename count to length
* change all occurrences of 'count' to 'length' in tests
* format length command
* Refactor path subcommand argument handling
DefaultArguments are no longer passed to each subcommand. Instead, each
subcommand has its own Path<xxx>Arguments. This means that it is no
longer necessary to edit every single path subcommand source file when
changing the arguments struct.
* Add new path join subcommand
Makes it easier to create new paths. It's just a wrapper around Rust's
Path.join().
* fix case where parent_name was {nu, term} and possibly others in the future by doing an extra test first to see if if the *parent_name key actually exists in cmap
* update with help generate_docs testing
`drop` is used for removing the last row. Passing a number allows dropping N rows.
Here we introduce the same logic for dropping columns instead.
You can certainly remove columns by using `reject`, however, there could be cases
where we are interested in removing columns from tables that contain, say, a big
number of columns. Using `reject` becomes impractical, especially when you don't
care about the column names that could either be known or not known when exploring
tables.
```
> echo [[lib, extension]; [nu-core, rs] [rake, rb]]
─────────┬───────────
lib │ extension
─────────┼───────────
nu-core │ rs
rake │ rb
─────────┴───────────
```
```
> echo [[lib, extension]; [nu-core, rs] [rake, rb]] | drop column
─────────
lib
─────────
nu-core
rake
─────────
```
There are many use cases. Here we introduce the following:
- The rows can be rolled `... | roll` (up) or `... | roll down`
- Columns can be rolled too (the default is on the `left`, you can pass `... | roll column --opposite` to roll in the other direction)
- You can `roll` the cells of a table and keeping the header names in the same order (`... | roll column --cells-only`)
- Above examples can also be passed (Ex. `... | roll down 3`) a number to tell how many places to roll.
Basic working example with rolling columns:
```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| rename bit1 bit2 bit3 bit4 bit5 bit6 bit7 bit8
───┬──────┬──────┬──────┬──────┬──────┬──────┬──────┬──────
# │ bit1 │ bit2 │ bit3 │ bit4 │ bit5 │ bit6 │ bit7 │ bit8
───┼──────┼──────┼──────┼──────┼──────┼──────┼──────┼──────
0 │ 0 │ 0 │ 0 │ 0 │ 0 │ 1 │ 0 │ 0
───┴──────┴──────┴──────┴──────┴──────┴──────┴──────┴──────
```
We want to "shift" three bits to the left of the bitstring (four in decimal), let's try it:
```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| rename bit1 bit2 bit3 bit4 bit5 bit6 bit7 bit8
| roll column 3
───┬──────┬──────┬──────┬──────┬──────┬──────┬──────┬──────
# │ bit4 │ bit5 │ bit6 │ bit7 │ bit8 │ bit1 │ bit2 │ bit3
───┼──────┼──────┼──────┼──────┼──────┼──────┼──────┼──────
0 │ 0 │ 0 │ 1 │ 0 │ 0 │ 0 │ 0 │ 0
───┴──────┴──────┴──────┴──────┴──────┴──────┴──────┴──────
```
The tables was rolled correctly (32 in decimal, for above bitstring). However, the *last three header names* look confusing.
We can roll the cell contents only to fix it.
```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| rename bit1 bit2 bit3 bit4 bit5 bit6 bit7 bit8
| roll column 3 --cells-only
───┬──────┬──────┬──────┬──────┬──────┬──────┬──────┬──────
# │ bit1 │ bit2 │ bit3 │ bit4 │ bit5 │ bit6 │ bit7 │ bit8
───┼──────┼──────┼──────┼──────┼──────┼──────┼──────┼──────
0 │ 0 │ 0 │ 1 │ 0 │ 0 │ 0 │ 0 │ 0
───┴──────┴──────┴──────┴──────┴──────┴──────┴──────┴──────
```
There we go. Let's compute it's decimal value now (should be 32)
```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| roll column 3 --cells-only
| pivot bit --ignore-titles
| get bit
| reverse
| each --numbered { = $it.item * (2 ** $it.index) }
| math sum
32
