This package provides syntax highlighting for the shell zsh. It enables
|
|
|
|
|
highlighting of commands whilst they are typed at a zsh prompt into an
|
2015-10-20 14:56:10 +00:00
|
|
|
interactive terminal. This helps in reviewing commands before running
|
|
|
|
|
them, particularly in catching syntax errors.

FAQ

### Why must `zsh-syntax-highlighting.zsh` be sourced at the end of the `.zshrc` file?
|
|
|
|
|
|
2016-10-07 14:21:57 +00:00
|
|
|
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,
|
2016-10-07 14:22:23 +00:00
|
|
|
`zsh-syntax-highlighting.zsh` hooks into ZLE by wrapping ZLE widgets. It must
|
|
|
|
|
be sourced after all custom widgets have been created (i.e., after all `zle -N`
|
|
|
|
|
calls and after running `compinit`) in order to be able to wrap all of them.
|
2016-10-07 14:21:57 +00:00
|
|
|
Widgets created after z-sy-h is sourced will work, but will not update the
|
2015-09-24 18:45:35 +00:00
|
|
|
syntax highlighting.
|
2015-01-26 09:08:31 +00:00
|
|
|
|
2020-08-09 10:54:01 +00:00
|
|
|
In zsh newer than 5.8 (not including 5.8 itself),
|
2016-10-07 14:21:57 +00:00
|
|
|
zsh-syntax-highlighting uses the `add-zle-hook-widget` facility to install
|
|
|
|
|
a `zle-line-pre-redraw` hook. 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.
|
|
|
|
|
|
2016-08-16 17:08:47 +00:00
|
|
|
### Does syntax highlighting work during incremental history search?
|
2016-03-29 20:13:46 +00:00
|
|
|
|
2017-07-30 17:06:14 +00:00
|
|
|
Highlighting the command line during an incremental history search (by default bound to
|
|
|
|
|
to <kbd>Ctrl+R</kbd> in zsh's emacs keymap) requires zsh 5.4 or newer.
|
2017-02-07 17:19:18 +00:00
|
|
|
|
2017-07-30 17:06:14 +00:00
|
|
|
Under zsh versions older than 5.4, the zsh-default [underlining][zshzle-Character-Highlighting]
|
2016-08-16 17:09:42 +00:00
|
|
|
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.)
