The workflow-osx package


a "Desktop Workflow" monad with Objective-C bindings.

includes bindings to:

for example:

 -- | cut the currently highlighted region
 cut :: (MonadWorkflow m) => m String
 cut = do
  sendKeyChord [CommandModifier] XKey
  delay 250
 -- | transform the currently highlighted region, via the clipboard
 transformClipboard :: (MonadWorkflow m) => (String -> String) -> m ()
 transformClipboard f = do
  contents <- cut
  setClipboard (f contents)
  sendKeyChord [CommandModifier] VKey

see Workflow.OSX for several more examples

(this package is on hackage for convenience, but it's still a prerelease)

a (free) monad, with Objective-C bindings, for "Workflow" actions.

the build

foreign dependencies always complicate the build process. it's known to work with the following:


platform agnosticism

exploit the free monad's flexibility to define platform-agnostic workflows

problem: windows (Linux/Windows) versus processes (OS X)

problem: keyboards. Apple keyboards don't have the Windows key, Windows keyboards don't have the Apple key. some keyboards have a dozen random extra unbound keys.

automatic delay insertion

problem: currently, delays must be inserted manually. keyboard shortcuts in Emacs succeed with no delay. keyboard shortcuts in Chrome, like closing a tab with M-w, may drop without a long delay (like 250ms). furthermore, different actions need different delays between them (e.g. inserting text into Chrome can be done without delay).
