Types

type JSM = ReaderT JSContextRef IO

The JSM monad keeps track of the JavaScript context.

Given a JSM function and a JSContextRef you can run the function like this...

runReaderT jsmFunction javaScriptContext

For an example of how to set up WebKitGTK+ see tests/TestJSaddle.hs

data JSContextRef

Instances

MakeArgs arg => MakeArgs (JSM arg)

Methods

makeArgs :: JSM arg -> JSM [JSVal]

Running JSaddle given a JSContextRef

runJSaddle :: MonadIO m => JSContextRef -> JSM a -> m a

run :: Int -> JSM () -> IO ()

Exception Handling

syncPoint :: JSM ()

Forces execution of pending asyncronous code

syncAfter :: JSM a -> JSM a

Forces execution of pending asyncronous code after performing f

catch :: Exception e => JSM b -> (e -> JSM b) -> JSM b

Wrapped version of catch that runs in a MonadIO that works a bit better with JSM

bracket :: JSM a -> (a -> JSM b) -> (a -> JSM c) -> JSM c

Wrapped version of bracket that runs in a MonadIO that works a bit better with JSM
