# Syntax Highlighting

Integrates [zsh-syntax-highlighting][1] into Prezto.

This module must be loaded _before_ the _`prompt`_ module.

Additionally, if this module is used in conjunction with the
[_`history-substring-search`_][2] module, this module must be loaded _before_
the _`history-substring-search`_ module.

To elaborate, the relative order of loading the modules would be
_`syntax-highlighting`_, _`history-substring-search`_ and _`prompt`_.

## Contributors

New features and bug fixes should be submitted to the
[zsh-syntax-highlighting][1] project according to its rules and regulations.
This module will be synchronized against it.

## Settings

### Highlighting

To enable highlighting for this module only, add the following line to
_`${ZDOTDIR:-$HOME}/.zpreztorc`_:

```sh
zstyle ':prezto:module:syntax-highlighting' color 'yes'
```

### Highlighters

Syntax highlighting is accomplished by pluggable [highlighters][3]. This module
only enables the _main_ highlighter by default.

To enable all highlighters, add the following to
_`${ZDOTDIR:-$HOME}/.zpreztorc`_.

```sh
zstyle ':prezto:module:syntax-highlighting' highlighters \
  'main' \
  'brackets' \
  'pattern' \
  'line' \
  'cursor' \
  'root'
```

### Highlighting Styles

Each syntax highlighter defines styles used to highlight tokens.

To highlight, for example, builtins, commands, and functions in blue instead of
green, add the following to _`${ZDOTDIR:-$HOME}/.zpreztorc`_:

```sh
zstyle ':prezto:module:syntax-highlighting' styles \
  'builtin' 'bg=blue' \
  'command' 'bg=blue' \
  'function' 'bg=blue'
```
