GSoC — Final Report!

So finally it’s over. Today is the last date for submission of the GSoC project. This entire ride was a lot informative as well as an experience filled one. I thank Indic Project organisation for accepting my GSoC project and my mentors Navaneeth K N and Jishnu Mohan for helping me out fully throughout this project.

The project kicked off keeping in mind of incorporating the native libvarnam shared library with the help of writing JNI wrappers. But unfortunately the method came to a stall when we were unable to import the libraries correctly due to lack of sufficient official documentations. So my mentor suggested me an alternative approach by making use of the Varnam REST API. This has been successfully incorporated for 13 languages with the necessity of the app requiring internet connection. Along with it, the suggestions which come up are also the ones returned by Varnam in the priority order. I would be contributing further to Indic Project to make the library method work in action. Apart from that see below the useful links,

  • this and this is related to adding a new keyboard with “qwerty” layout.
  • this is adding a new SubType value and a method to identify TransliterationEngine enabled keyboards.
  • this is adding the Varnam class and setting the TransliterationEngine.
  • this and this deals with applying the transliteration by Varnam and returning it back to the keyboard.
  • this is the patch to resolve the issue, program crashes on switching keyboards.
  • this makes sure that after each key press, the displayed word is refreshed and the transliteration of the entire word is shown.
  • this makes sure that on pressing deletion, the new word in displayed.
  • this creates a template such that more keyboards can be added easily.
  • this makes sure that the suggestions appearing are directly from the Varnam engine and not from the inbuilt library.
  • The lists of the commits can be seen here which includes the addition of layouts for different keyboards and nit fixes.

The project as a whole is almost complete. The only thing left to do is to incorporate the libvarnam library into the apk and then we can call that instead of the Varnam class given here. The ongoing work for that can be seen below,
