Documentation

Hi, As in every project, documentation of GfxPrim is lagging behind the code. Lately, I grew very fond of in-header documentation for individual functions and structures, as that is much easier to keep up to date and with just a little in-code documentation, keeping the two in sync is a hassle. How could we easily and simply do some doctext extraction? I thought about several ways: * Doxygen. I have no experience with it and it seems to be a bit too involved for us, but it is an option. * Some home-grown AsciiDoc extraction from comments. Could specify the target file in the tag, these could be included by regular docs. Example: /* SOME_SPECIAL_TAG target_file * int f(int x) * Does useful things * More asciidoc markup */ int f(int x) {return 0;} * Some other tool (mkdoc, doxygen (parsing only) + breathe + sphinx, whatever you prefer) The main idea is to avoid duplication, keep information together, simplify doc writing and stale data spotting and updating. What do you think? Tomas

Hi! As you may know the default type resulting from divison in python changed from int to float which results in type errors in GP_Convert_Scale.gen.h.t. The new integer division is no done by // which doesn't work in older python versions. I suppose we need to add explicit rounding to places when integer division is expected. -- metan
