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` associative array.
|
|
Navigate into each highlighter directory to see what styles (keys) it defines;
|
|
the syntax for values is the same as the syntax of "types of highlighting" of
|
|
the zsh builtin `$zle_highlight` array, which is documented in [the `zshzle(1)`
|
|
manual page][zshzle-Character-Highlighting].
|
|
|
|
[zshzle-Character-Highlighters]: http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#Character-Highlighting
|
|
|
|
Some highlighters support additional configuration parameters; see each
|
|
highlighter's documentation for details.

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 and
|
|
non-zero otherwise, 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)
