What is MarkdownPapers?

MarkdownPapers is a java implementation of Markdown language created by John Gruber in collaboration with Aaron Swartz, which provides an easy-to-read, easy-to-write plain text format that takes many cues from existing conventions for marking up plain text in email.

This implementation consist in parser built from a JAVACC grammar definition that produces an abstract syntax tree (AST) where transformations are performed following the Visitor Pattern.

Quick example

The most prominent component would be org.tautua.markdownpapers.Markdown which receives a java.io.Reader (input content) and java.io.Writer (output). 

Reader in = new FileReader("in.md");
Writer out = new FileWriter("out.html");

Markdown md = new Markdown();
md.transform(in, out);

And if you need to handle the AST by your own... 

Reader in = new FileReader("in.md");
Visitor v = new HtmlEmitter();
Parser parser = new Parser(in);

Document doc = parser.parse();
doc.accept(v);
