Hi all, I'd like a tool that takes a .cabal file as input and produces a list of all dependencies (recursive, all the way to 'base') and some metadata for each (most importantly, LICENSE) Does this already exist, or will I to write it myself? I notice that there's a patch by Trevor Elliot to either Cabal or cabal-install that does something similar [1], and I know that Magnus Therning wrote a little tool that creates a GraphViz graph [2]... so it seems like all the pieces are there already. But is there anything in some sort of ready-to-go just-works state, doing everything including interacting with hackage and sucking down the cabal files it needs, etc? Thanks, Eric [1]: http://www.haskell.org/pipermail/cabal-devel/2010-October/006657.html [2]: http://therning.org/magnus/archives/534 -- Eric Kow http://erickow.com

Talking about Hackage, in an ideal Hackage this information should be displayed right into the package's front page as well. One may have wishes, right? =) Cheers, -- Felipe.

cab[0] can do that, for installed packages:
cab deps -i -r -a vector
will generate a list of licenses for vector and the packages it depends
upon, like this:
base 4.3.1.0 BSD3 ""
ghc-prim 0.2.0.0 BSD3 ""
rts 1.0 BSD3 ""
ffi 1.0 BSD3 ""
integer-gmp 0.2.0.3 BSD3 ""
ghc-prim 0.2.0.0 BSD3 ""
rts 1.0 BSD3 ""
ffi 1.0 BSD3 ""
rts 1.0 BSD3 ""
ffi 1.0 BSD3 ""
primitive 0.4.0.1 BSD3 "Roman Leshchinskiy
