Hello Guys, I have started to extend Cabal with new feature. What I need is to have multiple Haskell source directories for one package. This feature is not substantial if you are packaging library, since it is supposed to have hierarchical namespace, but it is useful if you have executable. It is not mandatory to have hierarchical namespace for executables but if you are using flat namespace then with Cabal you will be restricted to keep all your source files in single directory. The extension that I have in mind will allow to break this restriction. GHC source tree is a good example of such type of project. It uses flat namespace but its source files are separated in multiple directories. The only visible change that is required is to replace hs-source-dir field to hs-source-dirs where the latter will accept a list of directories. The parser can still accept hs-source-dir for backward compatibility. I would like to hear any suggestions or objections against this extensions. I don't want to waste my time if this extension will not be accepted. Cheers, Krasimir
