Big refactoring.
* Don't override user defined styles * Better modularisation of highlighters * Allow to define which highlighters are activated * Allow to define the order in which they are defined * Minor performance optimizations * Fixed some variables leak * Improve documentation * Brackets highlighter: use ZSH_HIGHLIGHT_STYLES instead of a specific array

zsh-syntax-highlighting / highlighters
|
||||
======================================
|
||||
|
||||
Syntax highlighting is done by pluggable highlighters:
|
||||
|
||||
* [***main***](main) - the base highlighter, and the only one active by default.
|
||||
* [***brackets***](brackets) - matches brackets and parenthesis.
|
||||
* [***pattern***](pattern) - matches user-defined patterns.
|
||||
|
||||
|
||||
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)
|
||||
|
||||
|
||||
How to tweak highlighters
|
||||
-------------------------
|
||||
|
||||
Highlighters look up styles from the `ZSH_HIGHLIGHT_STYLES` array. Navigate into each highlighter directory to see what styles it defines and how to configure it.
|
||||
|
||||
|
||||
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, 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)

zsh-syntax-highlighting / highlighters / brackets
|
||||
=================================================
|
||||
|
||||
This is the ***brackets*** highlighter, that highlights brackets, parenthesis and matches them.
|
||||
|
||||
|
||||
How to activate it
|
||||
------------------
|
||||
To activate it, add it to `ZSH_HIGHLIGHT_HIGHLIGHTERS`:
|
||||
|
||||
ZSH_HIGHLIGHT_HIGHLIGHTERS=( [...] brackets)
|
||||
|
||||
|
||||
How to tweak it
|
||||
---------------
|
||||
This highlighter defines the following styles:
|
||||
* `bracket-error` - unmatched brackets
|
||||
* `bracket-level-N` - brackets with nest level N
|
||||
|
||||
To override one of those styles, change its entry in `ZSH_HIGHLIGHT_STYLES`, for example in `~/.zshrc`:
|
||||
|
||||
# To define styles for nested brackets up to level 4
|
||||
ZSH_HIGHLIGHT_STYLES[bracket-level-1]='fg=blue,bold'
|
||||
ZSH_HIGHLIGHT_STYLES[bracket-level-2]='fg=red,bold'
|
||||
ZSH_HIGHLIGHT_STYLES[bracket-level-3]='fg=yellow,bold'
|
||||
ZSH_HIGHLIGHT_STYLES[bracket-level-4]='fg=magenta,bold'
|
||||
|
||||
The syntax for declaring styles is [documented here](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#SEC135).

zsh-syntax-highlighting / highlighters / main
|
||||
=============================================
|
||||
|
||||
This is the ***main*** highlighter, that highlights:
|
||||
|
||||
* Commands
|
||||
* Options
|
||||
* Arguments
|
||||
* Paths
|
||||
* Strings
|
||||
|
||||
How to activate it
|
||||
------------------
|
||||
To activate it, add it to `ZSH_HIGHLIGHT_HIGHLIGHTERS`:
|
||||
|
||||
ZSH_HIGHLIGHT_HIGHLIGHTERS=( [...] main)
|
||||
|
||||
This highlighter is active by default.
|
||||
|
||||
|
||||
How to tweak it
|
||||
---------------
|
||||
This highlighter defines the following styles:
|
||||
* `unknown-token` - unknown tokens / errors
|
||||
* `reserved-word` - shell reserved words
|
||||
* `alias` - aliases
|
||||
* `builtin` - shell builtin commands
|
||||
* `function` - functions
|
||||
* `command` - commands
|
||||
* `hashed-command` - hashed commands
|
||||
* `path` - paths
|
||||
* `globbing` - globbing expressions
|
||||
* `history-expansion` - history expansion expressions
|
||||
* `single-hyphen-option` - single hyphen options
|
||||
* `double-hyphen-option` - double hyphen options
|
||||
* `back-quoted-argument` - backquoted expressions
|
||||
* `single-quoted-argument` - single quoted arguments
|
||||
* `double-quoted-argument` - double quoted arguments
|
||||
* `dollar-double-quoted-argument` - dollar double quoted arguments
|
||||
* `back-double-quoted-argument` - back double quoted arguments
|
||||
* `assign` - variable assignments
|
||||
* `default` - parts of the buffer that do not match anything
|
||||
|
||||
To override one of those styles, change its entry in `ZSH_HIGHLIGHT_STYLES`, for example in `~/.zshrc`:
|
||||
|
||||
# To differentiate aliases from other command types
|
||||
ZSH_HIGHLIGHT_STYLES[alias]='fg=magenta,bold'
|
||||
|
||||
# To have paths colored instead of underlined
|
||||
ZSH_HIGHLIGHT_STYLES[path]='fg=cyan'
|
||||
|
||||
# To disable highlighting of globbing expressions
|
||||
ZSH_HIGHLIGHT_STYLES[globbing]='none'
|
||||
|
||||
The syntax for declaring styles is [documented here](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#SEC135).

zsh-syntax-highlighting / highlighters / pattern
|
||||
================================================
|
||||
|
||||
This is the ***pattern*** highlighter, that highlights user defined patterns.
|
||||
|
||||
|
||||
How to activate it
|
||||
------------------
|
||||
To activate it, add it to `ZSH_HIGHLIGHT_HIGHLIGHTERS`:
|
||||
|
||||
ZSH_HIGHLIGHT_HIGHLIGHTERS=( [...] pattern)
|
||||
|
||||
|
||||
How to tweak it
|
||||
---------------
|
||||
To use this highlighter, associate patterns with styles in the `ZSH_HIGHLIGHT_PATTERNS` array, for example in `~/.zshrc`:
|
||||
|
||||
# To have commands starting with `rm -rf` in red:
|
||||
ZSH_HIGHLIGHT_PATTERNS+=('rm -rf *' 'fg=white,bold,bg=red')
|
||||
|
||||
The syntax for declaring styles is [documented here](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#SEC135).
