XNGMarkdownParser - A Markdown NSAttributedString Parser

This is a Markdown => NSAttributedString parser built on top of a flex parser. It takes an NSString and returns an NSAttributedString with markdown tags replaced by CoreText formatting attributes.

This project is a fork of NSAttributedMarkdownParser by NimbusKit: https://github.com/NimbusKit/markdown

Adding it to your Project

Manual

1. Drag all of the files from the src/ directory into your project.
2. Import XNGMarkdownParser.h in your project.
3. Create an instance of the parser object and pass it the string you wish to parse.
4. Plug the resulting NSAttributedString into your favorite NSAttributedString label implementation (like an UITextView)

XNGMarkdownParser *parser = [[XNGMarkdownParser alloc] init];
NSAttributedString *string = [parser attributedStringFromMarkdownString:@"This is __rad__."];

Further text customization

// this parser initializes only once and customizes fonts, line height and link color
+ (XNGMarkdownParser *)titleMarkdownParser {
    static dispatch_once_t onceToken;
    static XNGMarkdownParser *parser;
    dispatch_once(&onceToken, ^{
        parser = [[XNGMarkdownParser alloc] init];

        parser.paragraphFont = [UIFont xng_14Font];
        parser.boldFontName = [UIFont xng_14Font].fontName;
        parser.linkFontName = [UIFont xng_14Font].fontName;

        const CGFloat lineHeight = 18;
        NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
        paragraphStyle.minimumLineHeight = lineHeight;
        parser.topAttributes = @{
            NSParagraphStyleAttributeName: paragraphStyle,
            NSForegroundColorAttributeName: self.textColor
        };
    });

    return parser;
}
