zsh-syntax-highlighting
=======================
**[Fish shell](http://www.fishshell.com) like syntax highlighting for [Zsh](http://www.zsh.org).**
*Requirements: zsh 4.3.9+.*
How to install
--------------
### In your ~/.zshrc
* Download the script or clone this repository:
git clone git://github.com/nicoulaj/zsh-syntax-highlighting.git
* Source the script **at the end** of `~/.zshrc`:
source /path/to/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
* Source `~/.zshrc` to take changes into account:
source ~/.zshrc
### With oh-my-zsh
* Download the script or clone this repository in [oh-my-zsh](http://github.com/robbyrussell/oh-my-zsh) plugins directory:
cd ~/.oh-my-zsh/plugins/
git clone git://github.com/nicoulaj/zsh-syntax-highlighting.git
* Activate the plugin in `~/.zshrc` (in **last** position):
plugins=( [plugins...] zsh-syntax-highlighting)
* Source `~/.zshrc` to take changes into account:
source ~/.zshrc
How to tweak
------------
Syntax highlighting is done by pluggable highlighter scripts, see the [highlighters directory](zsh-syntax-highlighting/tree/master/highlighters)
for documentation and configuration settings.

zsh-syntax-highlighting / highlighters
======================================
Syntax highlighting is done by pluggable highlighters:
* [***main***](highlighters/main) - the base highlighter, and the only one active by default.
* [***brackets***](highlighters/brackets) - matches brackets and parenthesis.
* [***pattern***](highlighters/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).

zsh-syntax-highlighting / tests
===============================
Utility scripts for testing zsh-syntax-highlighting highlighters.
The tests expect the highlighter directory to contain a `test-data` directory with test data files. See the [main highlighter](../highlighters/main/test-data) for examples.
highlighting test
-----------------
[`test-highlighting.zsh`](tests/test-highlighting.zsh) tests the correctness of the highlighting. Usage:
zsh test-highlighting.zsh <HIGHLIGHTER NAME>
performance test
----------------
[`test-perfs.zsh`](tests/test-perfs.zsh) measures the time spent doing the highlighting. Usage:
zsh test-perfs.zsh <HIGHLIGHTER NAME>
