Roll up your sleeves and jump in! See the file TODO for our task list. Send patches to gtkgraph@vitelus.com. Please read the PHILOSOPHY file for coding style requirements. Here's some info about components of the program: * Parser Adapted from the bison multifunction calc example. C parts are in src/mathparse.c, yacc parts in src/mathparse.y. To generate the C code from the .y file, run bison with its name as the argument. This is only neccessary if you have modified it. * UI Straight GTK. I would have prefered to use C++, but that's not the recomended way to start GTK programming. (For the record: I hate the GTK object model of doing OOP in C. The UNIX community needs to admit that C++ is better for some things.)
