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…

Awesome, something good is happening :)

Cmake was giving me some trouble in the beginnning. After clearing all the dependency issues with the Cmake example, I was successfully able to run the endless-tunnel on my phone. Following the similar pattern of how the modules are being incorporated in the cmake app, we tried to incorporate the varnam module. The code for the attempt is given here.

Now there comes a problem :| I have documented the issue here,

After 9 days, there has still not been a single response :( So as an alternative we have decided to use the…

Why doesn’t it work!!!!!

Alright, for the past two weeks, me and my mentor have been trying a lot to call the varnam library in Java. First we went on trying to load the prebuilt library onto Android Studio and then use the methods in Java, which didn’t work :(

Now we are on a different route of compiling varnam during runtime. For this we are following the cmake example given here. Another thing to note that is, cmake requires canary Android Studio which can be downloaded here. It all started off well when it was seen that OSX has a problem running that.

Ooh boy, half way through GSoC and lot to be done. Finally we decided to do the entire project in Android Studio so that the later integration with Indic Keyboard would be easier. As said in the last post, I was in a state of completing the wrappers of varnam_init() and rest of the functions when a queue of challenges popped up.

First of all since we are moving out of the regular “PC” kind of architecture, storing the scheme files in a specific directory is still a problem. First we decided to store it in the internal storage of…

First of all, apologies for skipping the last week’s post. Last two weeks were somewhat a bit rocky :P

Discussion with my mentor suggested me to start of with the varnam_init method. Following with the initial trial build sent in a queue of issues to be resolved. Following are the errors in order

Finally after a few resolution of machine dependency and reinstallation I got it finally running :) I am now finishing varnam_init and will move on to the whole libvarnam in the coming week.

A week into GSoC has come to an end and it’s been a wonderful learning experience. My goal for the next couple of weeks would be to compile libvarnam in Android. So I decided to play around with the working and the flow of NDK to use native code in the Java program.

Android NDK code flow

The above image roughly explains the workflow of the NDK in Android. This tutorial explains very well as to how one can get started with NDK. The NDK knowledge would come very handy in the fututre for the progress on this project. …

Alright, so the almost one month long Community Bonding Period is over. During this time I went through the codebase of libvarnam extensively and understood the core structure of the module. Libvarnam is beautifully written and the whole credit goes to Navaneeth for the work he has done.

I have been working on this issue

and have come up with a fix as this pull request

Previously Varnam was only enabled for single words,

$ varnamc -s ml -t kerala

the issue was to enable Varnam for sentences. With the current…

Your proposal Add Varnam support to Indic Keyboard has been accepted!

Those were one of the few overwhelming words I have heard for a long time :’) So as it says, I have been selected for GSoC under Indic Project. My project is to add a new keyboard in the existing Indic Keyboard app with underlying Varnam module. Mentoring me would be two core contributors of this organization, Navaneeth and Jishnu.
