zsh-syntax-highlighting / highlighters / regexp
|
|
------------------------------------------------
|
|
|
|
This is the `regexp` highlighter, that highlights user-defined regular expressions. It's similar to 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_HIGHLIGHT_REGEXP+=('\bsudo\b' fg=123,bold)
|
|
|
|
This will highlight "sudo" only if it's surrounded by word boundary, 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].
|
|
|
