zsh-syntax-highlighting

Fish shell-like like syntax highlighting for Zsh.

Requirements: zsh 4.3.17+.

This package provides syntax highlighing for the shell zsh. It enables
highlighing 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.

Some examples:

Before:

How to install

See INSTALL.md.

FAQ

Why must `zsh-syntax-highlighting.zsh` be sourced at the end of the `.zshrc` file?

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
running compinit). Widgets created later will work, but will not update the
syntax highlighting.

Does syntax highlighting work during incremental history search?

Yes!

If you're using history-incremental-search-backward (by default bound to Ctrl+R
in zsh's emacs keymap) then it works with zsh version 5.3 and newer.

If you're using history-incremental-pattern-search-backward, then syntax highlighting works
in zsh 5.3.2 and newer due to a bug in zsh.

Under zsh 5.2 and older, 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.)

See issue #288 for details.

How are new releases announced?

There is currently no "push" announcements channel. However, the following
alternatives exist:

GitHub's RSS feed of releases: https://github.com/zsh-users/zsh-syntax-highlighting/releases.atom
An anitya entry: https://release-monitoring.org/project/7552/

How to tweak

Syntax highlighting is done by pluggable highlighter scripts. See the
documentation on highlighters for details and
configuration settings.
