Syntax highlighting is supported through highlighters. You may add your own Syntax definitions in therc directory. There is a syntax highlighting section in thehighlighters.asciidoc file.

There is a good overview of highlighters in Kakounehere.

https://github.com/insipx/kak-crosshairs provides automatic highlighting of current Line/Column

Theui.kak plugin provides commands and a user mode to quickly toggle various highlighters and related hooks.

First add asearch face. Here, it will emphasis the searched word in bold and italic without changing the foreground or background colors:

set-faceglobal search +bi

Then enable search highlighting. Dynregex is plugged on the content of the search register/:

add-highlighterglobal/search dynregex'%reg{/}'0:search

If you want a visual hint about code that exceeds a given width, try thecolumnhighlighter:

add-highlighterglobal/ column'%opt{autowrap_column}'default,red

...highlights the column named by theautowrap_column option with a red background, and will automatically move as the option is updated. Theautowrap_column option is used bythe autowrap script what column to wrap to, but even if you don't use autowrap's functionality, it's a good place to record the buffer's wrapping column so other wrapping and formatting hooks can find it.

The following highlighter will display words "FIXME"/"TODO"/"XXX"/"NOTE" in bold and reversed.

add-highlighterglobal/regex \b(TODO|FIXME|XXX|NOTE)\b0:default+rb

Faces can be taken from thecolorscheme files, which is what is usually done, or directly from the the list ofdefault faces:
