SyntaxKit

Version Carthage compatible CocoaPods compatible

SyntaxKit makes TextMate-style syntax highlighting easy. It works on iOS, watchOS, and OS X.

SyntaxKit was abstracted from Whiskey.

Building

SyntaxKit is written in Swift 2 so Xcode 7 is required. There aren't any dependencies besides system frameworks.

Installation

Carthage is the recommended way to install SyntaxKit. Add the following to your Cartfile:

github "soffes/SyntaxKit"

You can also install with CocoaPods:

pod 'SyntaxKit'

For manual installation, I recommend adding the project as a subproject to your project or workspace and adding the appropriate framework as a target dependency.

Usage

SyntaxKit uses

tmLanguage
and
tmTheme
files to highlight source code. None are provided with SyntaxKit. Thankfully, there are tons available at TextMate's GitHub org.

Basic Parsing

Once you have a language, you can get started:

import SyntaxKit

let path = "path to your .tmLanguage file" let plist = NSDictionary(contentsOfFile: path)! as [NSObject: AnyObject] let yaml = Language(dictionary: plist)

let parser = Parser(language: yaml)

Parser
is a very simple class that just calls a block when it finds something the language file knows about. Let's print all of the elements in this string:
let input = "title: \"Hello World\"\n"
parser.parse(input) { scope, range in
    print("\(scope) - \(range)")
}

scope
is the name of an element. This is something like
"string"
or
"constant.numeric"
.
range
is an
NSRange
struct representing where the scope falls in the input string.

Working with Attributed Strings

SyntaxKit also comes with

AttributedParser
. This is a simple subclass of
Parser
that knows how to work with themes.
let tomorrow = Theme(dictionary: themePlist)
let attributedParser = AttributedParser(language: yaml, theme: tomorrow)

attributedParser.parse(input) { scope, range, attributes in print("(scope) - (range) - (attributes)") }

Notice that

attributes
is the third paramenter to the block now. This is a dictionary of attributes you can give to
NSAttributedString
. Other values may be included here that don't work with
NSAttributedString
. You can do your own inspection and do something custom if you want.

AttributedParser
includes a convenience method for turning a
String
of source code into an
NSAttributedString
:
let attributedString = attributedParser.attributedStringForString(input)

Easy as that. This method takes an optional

baseAttributes
parameter to customize how the string is created. This is great if you want to specify a font, etc.

Custom Parsers

If you want to build your own parser (for example, to generate HTML) you can subclass whichever one meets your needs. Go wild.

Enjoy.
