Description

Helper functions to run Lua computations.

Synopsis

run :: LuaE e a -> IO a
runEither :: Exception e => LuaE e a -> IO (Either e a)
runWith :: State -> LuaE e a -> IO a

Documentation

run :: LuaE e a -> IO a Source #

Run Lua computation using the default HsLua state as starting point. Exceptions are masked, thus avoiding some issues when using multiple threads. All exceptions are passed through; error handling is the responsibility of the caller.

runEither :: Exception e => LuaE e a -> IO (Either e a) Source #

Run the given Lua computation; exceptions raised in Haskell code are caught, but other exceptions (user exceptions raised in Haskell, unchecked type errors, etc.) are passed through.

runWith :: State -> LuaE e a -> IO a Source #

Run Lua computation with the given Lua state. Exception handling is left to the caller; resulting exceptions are left unhandled.
