Fish shell like syntax highlighting for Zsh.
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.zshbe sourced at the end of the
zsh-syntax-highlighting works by hooking into the Zsh Line Editor (ZLE) and computing syntax highlighting for the command-line buffer as it stands at the time z-sy-h's hook is invoked.
In zsh 5.2 and older,
zsh-syntax-highlighting.zshhooks into ZLE by wrapping ZLE widgets. It must be sourced after all custom widgets have been created (i.e., after all
zle -Ncalls and after running
compinit) in order to be able to wrap all of them. Widgets created after z-sy-h is sourced will work, but will not update the syntax highlighting.
In zsh newer than 5.8 (not including 5.8 itself), zsh-syntax-highlighting uses the
add-zle-hook-widgetfacility to install a
zle-line-pre-redrawhook. Hooks are run in order of registration, therefore, z-sy-h must be sourced (and register its hook) after anything else that adds hooks that modify the command-line buffer.
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.
