Access to synfig's coding interface and coding langage used

Dear brothers,

I’d like to use the tool by coding and i can’t find the coding interface nor the programming langage.

I am i so dumb ?

There is not one unique coding interface. It dependes on what platform you’re working on. I use Xcode in OS X, others use Notepad++ on Windows or Geany in Linux. Create a good building environment is not a trivial task if you have not previous experience in programming.

Regarding the programming language it is mainly C++ and C. See code statistics on the Github repository.
