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_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]. | |||
See also: [regular expressions tutorial][perlretut], zsh regexp operator `=~` | |||
in [the `zshmisc(1)` manual page][zshmisc-Conditional-Expressions] | |||
