GSoC last week, GNOME final report! :)

4 minute read Published: 2013-09-21

It's been a while since my last post just after GUADEC. I've lost some time in August due moving to a new place in Campinas with two friends of mine. It was three weeks ago and I'm still feeling tired (I'm taking some time to get used with this new place).

Since then, I'm working on grilo-plugins and this post is all about what I've accomplished and what are the next steps after GSoC.

(The post is bigger then usual so... grab a cup of coffee !)

As I told before, Grilo has some commands that are translated to the source like Search and Browse operations. Good part of my project was translating this commands from Grilo to the Lua source and the result of this work was the lua-factory plugin.

The subset of commands available to Lua sources are: Search, Browse, Query, Resolve, May Resolve, Store and Remove. I've developed two Lua sources that implement those commands besides the last two (Store and Remove) due a library dependency that will be commented bellow.

Those Lua sources are Metrolyrics and Flickr which already exists as C source.

Due the limitations of the standards libraries of Lua and the need of interaction with Grilo itself the lua library was created. This is a set of lua modules that are helpful for the developers. Those modules could be wrappers of C librarys or custom functions.

For instance, to be able to interact with Flickr web service a wrapper of oauth library was created;

And all this were just the first steps;

Current issues that should be improved

The main goal of the GSoC project was being able to write plugins with Lua and them should be transparent to Grilo, making no difference between a C or Lua source. I feel that was accomplished but no without problems, lets check some of them 1:

The last week of GSoC Period

This week I'm not writing much code but trying to make a useful documentation to help other developers.

But as we can see in google's timeline, next week I'll be submitting the source code I've developed so far.

It will be the last week of GSoC but not my last in Grilo or in this project. Hopefully, I'll have a few more improvements in the end of October!

A big thanks to Juan for all the feedback, help and insights! I've made big steps these last three months and you help me out everytime :)

Final considerations

I've enjoyed a lot this period! I've learnt a lot! I've met amazing people! I've traveled more then 10'000Km to a beautiful city to attend a super conference! I've learnt Lua (and loving it!)

I'm lucky. Thanks to GNOME and Google for that!

Wow, you made it till here. You can reclaim a beer in the next GUADEC!

Did you know ? Grilo is a type of bug in Brazil ? A Cricket !

Grilo is a bug!
