GSoc:Week3 Update

This week I completed the porting of Katapayadi Numbers. So all the modules except for dhwani TTS and webfonts modules have been ported. I tried a hand at porting dhwani, which is written in C with C++ apis. The python module was using CDLL and ctypes to directly use the c binaries. I tried to compile dhwani from source only to get a zlib headers missing error. zlib was already installed in my system and I also checked for zlib.h in /usr/includes. It looks like some tinkering around will be required for getting this to compile. So I decided to try later with a binary and moved on to the webfonts.

Silpa has a webfonts module which provide webfonts for Indian languages which could be easily added to any site by simply linking a url. Since we have moved to flask most of the code had to be rewritten to get this module working. Now multiple fonts can be linked with a single url. I got the dynamic css part working but for some reason the fonts simply are not loading. The webfont module is using @font-face feature to include the fonts and this is good article by Paul Irish on getting it to work across all browsers. I will try to host the site on openshift and try again to make sure the issue is not due to any problem with serving them from localhost.

Also the webfonts module is written in two parts a normal python module which will fit into silpa and the webfonts serving api as a blueprint which allows me to simply attach it to flasks app object either at a urlprefix or a subdomain in a single line of code which is realy usefull. Flask is extremely flexible and you can organize your app as you please.
