data HooksSpec

defaultHooksSpec :: HooksSpec

Default HooksSpec that will not find any hooks. Be sure to add a directory with inDir, noRecurseDir or recurseDir.

inDir :: FilePath -> HooksSpec -> HooksSpec

Set the directory in which the hooks are to be found. This is the same as noRecurse

withArg :: Text -> HooksSpec -> HooksSpec

withEnv :: Text -> Text -> HooksSpec -> HooksSpec

withWorkingDir :: FilePath -> HooksSpec -> HooksSpec

recurseDir :: FilePath -> HooksSpec -> HooksSpec

noRecurseDir :: FilePath -> HooksSpec -> HooksSpec

closeFDs :: HooksSpec -> HooksSpec

noCloseFDs :: HooksSpec -> HooksSpec

data ProcessData

ProcessData

Fields

pName :: FilePath

pData :: (Maybe Handle, Maybe Handle, Maybe Handle, ProcessHandle)

pHandle :: ProcessData -> ProcessHandle

runHooks :: HooksSpec -> IO (Either String [ProcessData])

Create all exectuables in the directory specified by the

runHooksInDir :: FilePath -> [Text] -> IO (Either String [ProcessData])

Run all hooks in the directory with the given arguments. See defaultHooksSpec for other configuration.

runAndWaitForHooksInDir :: FilePath -> [Text] -> IO (Either String [ExitCode])

Run hooks in directory with given arguments and wait for completion. This is the straightforward combination of runHooksInDir and waitForHooks.

waitForHooks :: [ProcessData] -> IO [ExitCode]

Wait for all hooks to finish running.

readStdErr :: ProcessData -> IO Text

Read stderr from processdata waiting for the process to exit. It will yield an empty string if no stderr handle is given.

readStdOut :: ProcessData -> IO Text

Read stdout from processdata waiting for the process to exit. It will yield an empty string if no stdout handle is given.

data StdStream
