If I add some import, what do I now depend on that I didn't before?
It's the new closure minus the previous one. If I already imported that module, it's Left and the paths that show I already depend. If I didn't, I added it, plus whatever non-zero adds it implies. TODO If it's circular, report that!
rmDep :: CachedGraph -> Module -> Module -> [(Module, Set Module)] Source #
If I remove Perform.Signal from Derive.ScoreT, who now has fewer deps?
findWeakLinks :: CachedGraph -> [(Int, ((Text, Text), [(Module, Set Module)]))] Source #
This implements the brute-force way of seeing which single imports can be removed for the greatest reduction in dependencies.
closureList :: Graph -> Module -> [Module] Source #
Closure as a list so you can abort as soon as you find something.
generate
cacheGraph :: IO () Source #
generateGraph :: IO Graph Source #
fileToModule :: FilePath -> Module Source #
cppInImports :: Set FilePath Source #
Hardcoded list of modules that use CPP to determine their imports. TODO duplicated with Shakefile.ccInImports.
