Requirements: zsh 4.3.11+.
This package provides syntax highlighting for the shell zsh. It enables highlighting of commands whilst they are typed at a zsh prompt into an interactive terminal. This helps in reviewing commands before running them, particularly in catching syntax errors.
zsh-syntax-highlighting.zsh wraps ZLE widgets. It must be sourced after all
custom widgets have been created (i.e., after all
zle -N calls and after
compinit). Widgets created later will work, but will not update the
Highlighting the command line during an incremental history search (by default bound to to Ctrl+R in zsh's emacs keymap) requires zsh 5.4 or newer.
Under zsh versions older than 5.4, the zsh-default underlining of the matched portion of the buffer remains available, but zsh-syntax-highlighting's additional highlighting is unavailable. (Those versions of zsh do not provide enough information to allow computing the highlighting correctly.)
There is currently no "push" announcements channel. However, the following alternatives exist:
Syntax highlighting is done by pluggable highlighter scripts. See the documentation on highlighters for details and configuration settings.
