The cabal-sort package

[Tags:bsd3, program]

If you have a bunch of packages you may want to compile or recompile, then you need an order of compilation that meets the dependencies. Given a number of cabal package files, this program reads all those files and emits them topologically sorted according to their dependencies. This way you can compile many packages at once, say if a very low-level package has changed.

For compiling a couple of packages from their local darcs repositories in the right order, you may run something like

 for dir in `find . -name "*.cabal" | fgrep -v _darcs | xargs cabal-sort --info=dir`; do (cd $dir && cabal install); done

For uploading a set of packages to Hackage in the right order you may run

 for dir in `find . -name "*.cabal" | fgrep -v _darcs | xargs cabal-sort --info=dir`; do (cd $dir && rm dist/*.tar.gz && cabal sdist && cabal upload dist/*.tar.gz); done

Problem: Given packages A, B, C, where C depends on B and B depends on A, and you call

 cabal-sort C.cabal A.cabal

then the emitted order of packages may be wrong, because cabal-sort does not get to know the dependency of C on B. Even if the order is correct, B.cabal is missing in the output and thus the list of cabal files cannot immediately be used for a sequence of cabal-install runs.
