FYI, macro recording is on our roadmap found at http://wiki.gimp.org/index.php/Roadmap. > 2) can anyone give me a head start on how should I modify my hack so that it is more readable to others? Spreading the log function into tens of files certainly breaks most guideline one should follow when writing object-oriented program :D I'm convinced (others are not) we should use the proven http://en.wikipedia.org/wiki/Command_pattern and http://en.wikipedia.org/wiki/Composite_pattern for macro recording and wrote some patches a while ago that introduced a GimpCommand and a GimpGroupCommand class. I didn't have time to even turn it into a working prototype however. It will be necessary to make some extensions to the above patterns. For example, you may have noticed that GIMP is quite quick to Undo and Redo, in particular for time consuming pixel processing operations. That's because the undo stack contains the tiles with the resulting pixels, not only parameters used to get that result. When Redoing, the tiles with the result can quickly be applied. I'm imagining that we'd have code that would look something like this: gimp_expensive_command_execute (...) { if (gimp_expensive_command_result_cached (...)) gimp_expensive_command_apply_cached_result (...); else // Do time-consuming stuff } We don't want to start each GimpCommand with that if case though, so an abstraction will be needed. This is not a trivial refactoring, but we need to do it eventually.
