Types and functions for interacting with i3's IPC mechanism

Commonly, you just want to subscribe to a set of event types and do something with the response:

import qualified I3IPC.Subscribe   as Sub
import           I3IPC              ( subscribe )

main :: IO ()
main = subscribe print [Sub.Workspace, Sub.Window]

Other times, you want to send some kind of command to i3, or get a specific response as a one-time action.

import           I3IPC              ( connecti3
                                    , getWorkspaces
                                    )

main :: IO ()
main = do
    soc <- connecti3
    print getWorkspaces

All of the "getX" functions are provided for convenience, but also exported are the building blocks to write whatever you like. There are strict and non-strict variants provided, the tick (') implies strict. For instance, the above could be written as:

import qualified I3IPC.Message     as Msg
import           I3IPC              ( connecti3
                                    , receiveMsg
                                    )

main :: IO ()
main = do
    soc <- connecti3
    print $ Msg.sendMsg soc Msg.Workspaces >> receiveMsg soc
