DocBook Editor 1

It's been very quiet in here. This month has been a marathon of coding and a lot of other events on the home front.

First off, a few non-GSoC related developments:

• I finished college. (Phew!)
  
• I got placed in Red Hat as an Associate Software Engineer. (gleee!)
  
• I won the Sun India Code For Freedom contest for my B. Tech Project. (ZOMG!! yes that was COMPLETELY unexpected!)
• I went out for a small trip this weekend after almost 2 years.
  

Now to the DocBook Editor...

I started off by learning XSLT (tough!) and making an initial RPM for Beacon and submitted it for review. I created a Feature page and worked on deciding on an initial subset with the help of the Fedora-docs list.

Here are a few links to complement the above:

https://fedoraproject.org/wiki/DocBook_Editor_Documentation
https://fedoraproject.org/wiki/Features/DocBookEditor
https://fedoraproject.org/wiki/DocBook_Editor

Then, I constructed an initial XSL by referring to the example DocBook file in the Fedora Documentation repository and based on the initial tag set that was selected after a community review.

Initially, I fixed a few bugs in Beacon to learn the source code and worked on making it more convenient to add plug-ins by changing the implementation so that beacon needs only a DTD from the plug-in makers (which is us) rather than having us code the whole Javascript. A successful implementation of this would save a lot of time in feature addition and creation of plugins.

Apart from the DTD, I was learning the tools more from implementation perspective like JavaScript and jQuery library used in Beacon.

The last week has been the most exciting. Working with Nandeep Mali, the lead Beacon dev and my point of contact for the Beacon upstream, we got the DTD feature implemented to some extent and its working like a charm. The WYSIWYM is also working and just few more additions need to be done to make this a solid XML editor.

The DTD is actually a giant Javascript object which contains details about every node and its structure (like child, parent, siblings). One may think that why not use an existing WYSIWYG editor like TinyMCE. This is not very feasible because WYSIWYG editors are notorious for
the output they produce. This is what Beacon is trying to avoid by adding a different type of editor. The user will be places with a fill-in-the-blanks type of editor so the generated XML will retain its sanity and conform to Docbook DTD. Makes it easy for the Docs team as well.

Now for the treat: http://dev.gentooexperimental.org/~n9986/beacon/editor/

The above URL is a demo of what we have been working with (I hope the Gentoo URL is not a problem. Beacon was a Gentoo SoC project and I cannot get PHP with JSON and XSLs on my fedora account).

The work till now mainly consisted of writing the XSLs for DocBook and making changes to the beacon core. One final enhancement in the usability of beacon would be a drag and drop feature that has not been committed so far as it is very slow at the moment. Once that is ready it will be very easy to add nodes at any point and still not mess up the corresponding XML.

I have been writing the DTD for DocBook since yesterday and will be able to commit it by very soon. So we can expect another blog post about it very soon.

Has been a fun journey so far. More to come in the next post.
