Give it a go in a live textile web editor.
$ npm install textile-js
The basic interface mimics marked, the popular markdown parser. So if you use that in your project then you can support Textile as well with minimal effort.
Currently, the only supported option is
breaks which can be used to enable/disable the default behavior of line-breaking single newlines within blocks.
console.log( textile( "I am using __textile__." ) );
You can also get to the syntax tree, which uses JsonML.
var jsonml = textile.parse( text ); console.log( jsonml );
$ textile -o hello.html hello world ^D $ cat hello.html <p>hello world</p>
