rmList :: Ord a => [a] -> [a] -> [a] Source #
Efficient implementation of set like deletion on lists
>>>
"abcd" `rmList` "ad"
"bc">>>
"aaabcccd" `rmList` "ad"
"bccc"

mergeLibraries :: [Library] -> Library Source #
Merge multiple libraries into one, by concatenating all their fields.
libraryToGhciArgs :: Library -> ([String], [String], [String]) Source #
Convert a Library to arguments suitable to be passed to GHCi.
dropEnd :: Int -> [a] -> [a] Source #
Drop a number of elements from the end of the list.
dropEnd 3 "hello" == "he" dropEnd 5 "bye" == "" dropEnd (-1) "bye" == "bye" \i xs -> dropEnd i xs `isPrefixOf` xs \i xs -> length (dropEnd i xs) == max 0 (length xs - max 0 i) \i -> take 3 (dropEnd 5 [i..]) == take 3 [i..]
findCabalPackage :: HasCallStack => String -> IO FilePath Source #
solveCondTree :: CondTree ConfVar c a -> [(c, a)] Source #
Traverse the given tree, solve predicates in branches, and return its contents.
XXX: Branches guarded by Cabal flags are ignored. I'm not sure where we should get this info from.
