No, and I'd prefer to fix recipes instead of having a way to disable them. The numpy/scipy recipes are probably as aggressive as they are because that fixes the immediate problem with minimal effort while writing the recipe. The recipe should get a way to specify which dynamic imports are present, simular to the hardcoded knowlegde about the stdlib in modulegraph. That way py2app can include only the bits that are really necessary. IIRC the matplotlib recipe includes the entire package because of the data files that are in the package, including only the code doesn't work. > > - Is there a way to apply excludes after the recipe? As far as I can > tell, if the recipe includes it, excludes doesn't remove it. That's correct, and is a bug: user specified actions should override automatic actions, including the recipes.
