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`:
```zsh
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][zshzle-Character-Highlighting].
