It seems pandoc 1.13.1 package on hackage has gotten into an insonsistent state. I just noticed this strange situation with the dependency on http-client: pandoc.cabal at [1] has if flag(https) Build-Depends: http-client >= 0.3.2 && < 0.5, http-client-tls >= 0.2 && < 0.3, http-types >= 0.8 && < 0.9 cpp-options: -DHTTP_CLIENT pandoc.cabal found in [2] has if flag(https) Build-Depends: http-client >= 0.3.2 && < 0.4, http-client-tls >= 0.2 && < 0.3, http-types >= 0.8 && < 0.9 cpp-options: -DHTTP_CLIENT How can something like this even happen? /M [1]: http://hackage.haskell.org/package/pandoc-1.13.1/pandoc.cabal [2]: http://hackage.haskell.org/package/pandoc-1.13.1/src/pandoc.cabal -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus@therning.org jabber: magnus@therning.org twitter: magthe http://therning.org/magnus Any fool can write code that a computer can understand.
