= rust-selection-sort.kak

Sort selections by regular expression or lexicographically

== Example

. Imagine you want to sort these stages
+
[source,groovy]
----
stage('Package (#3)') {
    // ...
}

stage('Build (#2)') {
    // ...
}

stage('Initialize (#1)') {
    // ...
}

stage('Publish (#4)') {}
----

. Select the stage and stage body with: `%sstage<ret>MLM`
. Sort the selection by step number with: `:sort-selections #\d+<ret>` (sort on whole capture) or `:sort-selections "'.+?#(\d).+?'"` (sort on first capture group, which contains only the digits)
. Note if you just run `:sort-selections<ret>`

== Configuration

[source,sh,title='sh']
----
cargo install --git https://github.com/austenadler/rust-selection-sort.kak
----

[source,title='kakrc']
----
define-command sort-selections -params 0.. %{
    eval -save-regs '"' %{
        reg dquote %val{selections}
        eval %sh{
            regex="${1:-.*}"

            # TODO: Use a comand fifo to read/write selections
            eval set -- "$kak_quoted_selections"

            # TODO: Send additional parameters

            rust-selection-sort -r "$regex" $args -- "$@" > "$kak_command_fifo"
        }
        exec R
    }
}
----

== Usage

* Make multiple selections
* Run `sort-selections` to sort the selections lexicographically (TODO: implement a `sort -h` like feature)
* Run `sort-selections REGEX` to sort by regex match
** If the regex does not contain a capture group
** If the regex contains at least one capture group

== TODO

* I don't know what will happen with multiline strings
* Use 2 fifos for getting and sending selections since this should be faster than sending this to shell
* Send options (`-S`) to cli from kak
* Figure out how to change the `no_skip_whitespace` option name in the source
