A kakoune plugin like rainbow.
Highlights pairs of parentheses in the same color, recursive pairs are highlighted in a different color.
Add this plugin to your autoload folder.
Or use plug
plug 'jjk96/kakoune-rainbow'
execute :rainbow to highlight the current buffer once.
execute :rainbow-enable to highlight the current buffer continuously (note that this may be a bit laggy).
execute :rainbow-disable to remove the highlighter
The rainbow_highlight_background option sets whether the background of the part between braces should be highlighted.
You can override the rainbow_faces option to set your own faces.
Example:
set-option global rainbow_faces "rgb:ff0000" "rgb:00ff00" "rgb:0000ff"
You can also override the rainbow_opening option to set the opening parentheses regex.
Example:
set-option global rainbow_opening "[\[{(<]"
