Instances
identifyRepoFormat :: String -> IO RepoFormat
identifyRepoFormat URL
identifies the format of the repository
at the given address. Fails if we weren't able to identify the format.
tryIdentifyRepoFormat :: String -> IO (Either String RepoFormat)
tryIdentifyRepoFormat URL
identifies the format of the repository
at the given address. Return Left reason
if it fails, where
reason
explains why we weren't able to identify the format.
createRepoFormat :: [DarcsFlag] -> RepoFormat
writeRepoFormat :: RepoFormat -> FilePath -> IO ()
writeRepoFormat
writes the repo format to the given file.
writeProblem :: RepoFormat -> Maybe String
writeProblem form
tells if we can write to a repo in format form
.
It returns Nothing
if there's no problem writing to such a repository.
readProblem :: RepoFormat -> Maybe String
readProblem form
tells if we can read from a repo in format form
.
It returns Nothing
if there's no problem reading from such a repository.
readfromAndWritetoProblem :: RepoFormat -> RepoFormat -> Maybe String
readfromAndWritetoProblem form
tells if we can read from and write to a repo in
format form
. It returns Nothing
if there's no problem reading
and writing to such a repository.
formatHas :: RepoProperty -> RepoFormat -> Bool
