#252: haddock document generation fails for executables when a preprocessors is needed ----------------------------+----------------------------------------------- Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: HEAD Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: Linux | ----------------------------+----------------------------------------------- I'm coming to think I'm the only one who tries to generate haddock documentation for non library packages...;) When running "haddock --executables" with a package that has a module which is using a file extension to call a preprocessor, Haddock.getModulePaths will die with: Setup.lhs: can't find source for module moduleName If I add a library stanza to the cabal file, the problem is solved. This issue affects HEAD only. I must confess I do not understand why this happens, and I'm puzzled. But I don't know the cabal source enough, so I'll leave this to the expert ones. Cheers, Andrea Rossato ps: maybe even the short summary could be edited to better describe the problem. An English native speaker could be quite helpful with this...:-) -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/252> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

Since the debian bug was filed there are several more feature of the haddock command, perhaps they solve the problem. If not, perhaps the problem could be explained further. What problem are we trying to solve here that would require passing extra options to haddock, and what extra options would one use? -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/196> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

So we should check for these problems. At the moment the OS is just a String . We should decide if we want to use an enumeration or leave it more flexible and just warn about unknown ones.
