zsh-syntax-highlighting / highlighters / regexp

This is the regexp highlighter, that highlights user-defined regular expressions. It's similar to the pattern highlighter, but allows more complex patterns.

How to tweak it

To use this highlighter, associate regular expressions with styles in the ZSH_HIGHLIGHT_REGEXP associative array, for example in ~/.zshrc:

typeset -A ZSH_HIGHLIGHT_REGEXP
ZSH_HIGHLIGHT_REGEXP+=('\bsudo\b' fg=123,bold)

This will highlight "sudo" only as a complete word, i.e., "sudo cmd", but not "sudoedit"

The syntax for values is the same as the syntax of "types of highlighting" of the zsh builtin $zle_highlight array, which is documented in the zshzle(1) manual page.
