kakoune-expand

kakoune plugin to select increasingly larger regions of text using a single command. Largely inspired by Delapouite's expand-region. This plugin should be mostly seen as an alternative implementation.

Setup

Add expand.kak to your autoload dir: ~/.config/kak/autoload/, or source it manually.

You need at least Kakoune v2019.01.20 to use this plugin.

Usage

Simply call the expand command to select the smallest region that is bigger than the current.

It is possible to configure the expansion commands that are run by modifying the option expand_commands. The default value (documented below) should be suitable for C-style languages. Be mindful of double expansion.

declare-option str expand_commands %{
    expand-impl %{ exec <a-a>b }
    expand-impl %{ exec <a-a>B }
    expand-impl %{ exec <a-a>r }
    expand-impl %{ exec <a-i>i }
    expand-impl %{ exec '<a-:><a-;>k<a-K>^$<ret><a-i>i' } # previous indent level (upward)
    expand-impl %{ exec '<a-:>j<a-K>^$<ret><a-i>i' }      # previous indent level (downward)
}

I suggest the following mappings:

map -docstring "expand" global user e ': expand<ret>'

# 'lock' mapping where pressing <space> repeatedly will expand the selection
declare-user-mode expand
map -docstring "expand" global expand <space> ': expand<ret>'
map -docstring "expand ↻" global user E       ': expand; enter-user-mode -lock expand<ret>'

Tests

The test.kak_ file contains tests for the plugin. To execute these tests, simply run kak -n -e 'source test.kak_ ; quit': if the kakoune instance stays open, the tests have somehow failed and the current state can be inspected.
