A recent comment by Yucheng on my preview of Dita4Hudson post finally motivated me to upload my starter code to SourceForge so that others can contribute and make use of it.
The plugin right now is mostly front-end code and does not yet run the DITA Open Toolkit transforms. The intent of the plugin is to very simply provide text fields that a user can enter any and all applicable transform parameters for a given output type and then in the background those would be passed to the toolkit in the appropriate form and basically be a command line call.
I would love to see others pick up where I left off. I hope to be able to continue working on it again in the future, but for now I have too much else going on. I would be happy to help someone out with getting going with it. Please comment or use the contact form to get in touch.
