The workaround is for a script to traverse the filesystem and generate a
list of modules that can then be copied into the .cabal for haddock and
Setup.hs for hpc. If anyone else is trying to do the same, here's the code:
http://hpaste.org/fastcgi/hpaste.fcgi/view?id=11224#a11224
script copied below:
import System.Directory(doesDirectoryExist, getDirectoryContents)
import Data.Tree(unfoldTreeM, flatten)
import Control.Monad(filterM)
import System.FilePath(splitDirectories, dropExtension, takeExtension)
import Data.List(sort, intercalate)
main :: IO ()
main = do
paths <- modules
putStrLn (cabal paths)
putStrLn (hpc paths)
cabal :: [String] -> String
cabal xs = header ++ intercalate sep xs
where
header = " exposed-modules: "
sep = ",\n "
hpc :: [String] -> String
hpc = concatMap include
where
include x = pre ++ x ++ "\""
pre = "\n , \"--include="
modules :: IO [String]
modules = do
paths <- filePaths "."
return [modName p | p <- paths, takeExtension p == ".hs"]
where
modName = intercalate "." . splitDirectories . dropExtension
filePaths :: FilePath -> IO [FilePath]
filePaths path = do
tree <- unfoldTreeM childPaths path
filterM (fmap not . doesDirectoryExist) (flatten tree)
childPaths :: FilePath -> IO (FilePath, [String])
childPaths dir = do
b <- doesDirectoryExist dir
fs <- if b then getDirectoryContents dir else return []
return (dir, [dir ++ "/" ++ p | p <- fs, head p /= '.'])

I have a cabal package that defines a few dozen modules, and I'm hoping to generate documentation and code coverage for all modules without listing each module explicitly.
currently my .cabal includes:
library exposed-modules: Language.Idl.Data, Language.Idl.Merge, Language.Idl.Parser, ...lots more...
my Setup.hs includes an explicit system call to hpc:
exec "hpc" ["markup" , "--include=Language.Idl.Data" , "--include=Language.Idl.Merge" , "--include=Language.Idl.Parser" ...all the same files as above... ]
Questions: 1) Is there a way to create haddock docs for /all/ modules, instead of just the ones listed by 'exposed-modules'? 2) Is there a way to query cabal for the list of modules? Or by chance has hpc recently been integrated with cabal?
Thanks, Greg
