@grimmy C support could be added pretty easily. And would be a good addition for the Library which is sort of a Rosetta Stone for GNOME.
Importing libraries and stuff is probably out of scope but hopefully we'll bring the live preview to GNOME Builder. Then it's just a matter of copy pasting C examples there.
Thanks for the feedback
@sonny I need to give GNOME Builder another try soon. Last time I was struggling with difference from sublime text and found myself having to write a number of plugins which is of course keeping me from working on the stuff I should be working on.
The one I remember struggling with the most was trying to add mercurial support and not being able to follow through the git plugin at all. That said this was like 2 years ago or so.
