Re-export the operations of the chosen raw frontend (determined at compile time with cabal flags).


Re-exported raw frontend

data FrontendSession Source

Session data maintained by the frontend.

startup :: String -> (FrontendSession -> IO ()) -> IO ()Source

Spawns the gtk input and output thread, which spawns all the other required threads. We create a separate thread for gtk to minimize communication with the heavy main thread. The other threads have to be spawned after gtk is initialized, because they call postGUIAsync, and need sview and stags.

frontendName :: StringSource

The name of the frontend.

nextEvent :: FrontendSession -> Maybe Bool -> IO (Key, Modifier)Source

Input key via the frontend. Fail if there is no frame to show to the player as a prompt for the keypress.

promptGetAnyKey :: FrontendSession -> SingleFrame -> IO (Key, Modifier)Source

Display a prompt, wait for any key. Starts in Push or None mode, stop in None mode. Spends most time waiting for a key, so not performance critical, so does not need optimization.

display :: FrontendSession -> Bool -> Bool -> Maybe SingleFrame -> IO ()Source

Add a frame to be drawn.
