SundownJni - Markdown bindings for Java

Parse Markdown and compile to HTML using the well-tested sundown C-library.

Installing

Download the source package, unzip and run make in the sundownJni directory. If the file README.html appears, everything works.

Then, add the file libSundownJni.so to your LD_LIBRARY_PATH by unsing something like export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:. or configuring in your IDE. Add the *.class files to your java class path.

Usage

This library includes a JNI adaptor for accessing the C methods from Java. The API is pretty simple:

String quote = new SundownJni().toHtml("This is *Sparta!*\n"));

You can pass Options objects to the constructor like this:

SundownJni parser = new SundownJni(
  new MarkdownOptions().setStrikethrough().setSuperscript().setAutolink(),
  new SundownJniOptions().setSmartypants(),
  new HtmlOptions().setToc()
);

All options are optional and disabled by default. For example, if you want to remove all (other) HTML tags from the input, you could do the following:

SundownJni parser = new SundownJni(null,null,new HtmlOptions().seSkipHtml());

The SundownJniOptions are not passed to sundown but used by the C code of the adaptor to enable Smartypants or TOC rendering.

This will construct you a paser which will extact a TOC from your embedded headlines:

SundownJni parser = new SundownJni(null,new SundownJniOptions().setToc(),null);

This will construct you a paser which will enable Smartypants:

SundownJni parser = new SundownJni(null,new SundownJniOptions().setSmartypants(),null);

Experimental

This library is very experimental and currently only tested with the following setup:
