This adds a general, platform independent example before the more detailed example. Also removes details about the reason of the platform dependency of some non-standard regular expressions, and replaces it with a hyperlink to the related Zsh document.

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+=('^rm .*' fg="red",bold)
This will highlight the whole line starting with rm (for all operating systems,
in contrast to the below example).
Some regex patterns are subject to the host platform, especially
the kernel. To highlight sudo only as a complete word, i.e., sudo cmd, but
not sudoedit:
-
GNU-Linux
typeset -A ZSH_HIGHLIGHT_REGEXP ZSH_HIGHLIGHT_REGEXP+=('\<sudo\>' fg=123,bold) -
BSD-based platforms
typeset -A ZSH_HIGHLIGHT_REGEXP ZSH_HIGHLIGHT_REGEXP+=('[[:<:]]sudo[[:>:]]' fg=123,bold)
Both would give the same results, but do not work on each other's system.
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.
