Hi all, I use below params for configure dyre: rebootParams :: Params Config rebootParams = defaultParams {projectName = "Main" ,realMain = manatee ,showError = rebootShowError ,cacheDir = Just $ return "/test/Download/cache/" ,configDir = Just getCurrentDirectory } There have two version of function `reboot` to reboot Master binary: reboot :: IORefObject -> IO () reboot ioRefObject = do rs <- rebootGetState ioRefObject relaunchWithBinaryState rs Nothing reboot :: IORefObject -> IO () reboot ioRefObject = do output <- customCompile rebootParams case output of Just o -> putStrLn o -- output recompile error Nothing -> do -- otherwise relaunch rs <- rebootGetState ioRefObject relaunchWithBinaryState rs Nothing Becuase i setup `projectName` with `Main`, so i want `dyre` recompile NECESSARY module when i change any module in my project. In first version of function `reboot`, i just use `relauncheWithBinaryState`, i found `dyre` just recompile all project when i modified Main.hs, if i modified any others module in project, `dyre` won't recompile those modified modules. In second version, i use `customCompile` for recompile, but this have another problem, `customComiple` use `-fforce-recomp` flags to remove all object files, so function `customComiple` will recompile all modules in project, and not just recompile NECESSARY modules. So how to make `dyre` just recompile NECCESSARY modules whatever i change any modules in project? Maybe add new option "--dyre-reconf-necessary" in `dyre`? Thanks! -- Andy
