Markdown to PDF

I wrote a Gradle script to convert a markdown file to a PDF. Despite being 38 lines it was quite a little challenge to discover which libraries needed to be strung together and how to use them. Hopefully this can help someone in the future.

import com.petebevin.markdown.MarkdownProcessor import org.xhtmlrenderer.pdf.ITextRenderer import org.ccil.cowan.tagsoup.Parser import org.apache.xalan.xsltc.trax.SAX2DOM import org.xml.sax.InputSource buildscript{ repositories { mavenCentral() mavenRepo urls: "http://scala-tools.org/repo-releases" mavenRepo urls: "http://download.java.net/maven/2/" } dependencies { classpath "org.markdownj:markdownj:0.3.0-1.0.2b4" classpath "org.ccil.cowan.tagsoup:tagsoup:1.2" classpath "org.xhtmlrenderer:core-renderer:R8" } } task build <<{ def source = "resume.markdown" def target = "resume.pdf" //Convert from markdown to html def mp = new MarkdownProcessor() def html = "<html><body>${mp.markdown((new File(source).text))}</body></html>" //Convert from html to w3c document def parser = new Parser() def sax2dom = new SAX2DOM() parser.setContentHandler(sax2dom); parser.setFeature(Parser.namespacesFeature, false); parser.parse(new InputSource(new ByteArrayInputStream(html.getBytes()))); //Use Document to create pdf ITextRenderer renderer = new ITextRenderer(); renderer.setDocument(sax2dom.getDOM(), null); renderer.layout(); renderer.createPDF((new File(target).newOutputStream())) }
