zsh-syntax-highlighting / highlighters

Syntax highlighting is done by pluggable highlighters:

  • main - the base highlighter, and the only one active by default.
  • brackets - matches brackets and parenthesis.
  • pattern - matches user-defined patterns.
  • cursor - matches the cursor position.
  • root - triggered if the current user is root.
  • line - applied to the whole command line

How to activate highlighters

To activate an highlighter, add it to the ZSH_HIGHLIGHT_HIGHLIGHTERS array in ~/.zshrc, for example:

ZSH_HIGHLIGHT_HIGHLIGHTERS=(main brackets pattern cursor)

How to tweak highlighters

Highlighters look up styles from the ZSH_HIGHLIGHT_STYLES array. Navigate into each highlighter directory to see what styles it defines and how to configure it.

How to implement a new highlighter

To create your own myhighlighter highlighter:

  • Create your script at highlighters/myhighlighter/myhighlighter-highlighter.zsh.

  • Implement the _zsh_highlight_myhighlighter_highlighter_predicate function. This function must return 0 when the highlighter needs to be called, for example:

      _zsh_highlight_myhighlighter_highlighter_predicate() {
        # Call this highlighter in SVN repositories
        [[ -d .svn ]]
      }
    
  • Implement the _zsh_highlight_myhighlighter_highlighter function. This function does the actual syntax highlighting, by modifying region_highlight, for example:

      _zsh_highlight_myhighlighter_highlighter() {
        # Colorize the whole buffer with blue background
        region_highlight+=(0 $#BUFFER bg=blue)
      }
    
  • Activate your highlighter in ~/.zshrc:

      ZSH_HIGHLIGHT_HIGHLIGHTERS+=(myhighlighter)
