highlighting-kate is a syntax highlighting library with support for
nearly one hundred languages.  The syntax parsers are automatically
generated from Kate syntax descriptions (https://kate-editor.org/),

program is provided, along with a utility for generating new parsers
from Kate XML syntax descriptions.
