kakeidoscope

A plugin for Kakoune which implements simple rainbow bracket highlighting. It does not parse language features and will thus highlight comments.

Installation

cargo install kakeidoscope

To load the necessary options and some useful functions for kakeidoscope, place the following snippet into your Kakoune configuration, which loads the file located at rc/kakeidoscope.kak.

evaluate-commands %sh{ kakeidoscope init }

The following snippet will additonally automatically highlight all windows.

hook global WinCreate .* kakeidoscope-enable-window

The following options are passed to kakeidoscope via the Kakoune command kakeidoscope-highlight. Configuring these should be enough if you rely only on kakeidoscope-highlight and kakeidoscope-enable-window to highlight. For more detail on the CLI options, see kakeidoscope help highlight.

declare-option str-list kakeidoscope_faces red yellow green cyan blue magenta
declare-option str-list kakeidoscope_pairs "{" "}" "(" ")" "[" "]"

For speed's sake, kakeidoscope_pairs should not be modified once set.

Examples

• Given {(])}, the {} and () pair would be highlighted (with {} as top-level and () as once-nested), and the ] would be ignored, as it does not close a pair.
• Given {([)}, the {, (, and [ would be highlighted (with { as top-level, ( as once-nested, and [ as twice-nested), and the ) and } would be ignored, as neither closes a pair.

Note that this plugin's behavior is not identical to Kakoune's show-matching highlighter, as the former uses stricter rules to find a pair.
