This is an Atlas plugin that will let you edit and run Processing sketches using codemirror and processingjs. See the project page for details and examples.
To use it, first clone your atlas project to your local directory and then do these commands:
$ mkdir theme
$ cd theme
$ npm install orm-coderunner-processingjs
This will install everything. You'll then need to use git to add them and commit them, then push the project back up.
