Hi Andy,

I feel that I should offer a disclaimer here: You are misusing Dyre somewhat by attempting to make it handle whole-program recompilation. It is designed to recompile a single configuration file, generally against an installed library form of the application. Some of its code, specifically the part that decides when to recompile, is based almost entirely on this assumption. I use dyre for develop dynamic gtk application, so i hope dyre do whole-program recompilaton and just recompile necessary files. Just recompile single file or force recompile all modules is not my desire.

It's better if dyre's support single file recompliation and whole-program recompilation, isn't? :)

That aside, you should be able to accomplish your goals like this:

1. Set the 'forceRecomp' parameter (just added in Dyre 0.7.3) to 'False'. This will remove the '-fforce-recomp' flag from GHC's options. 2. Run your executable with the '--force-reconf' flag, which will cause Dyre to always enter the recompilation code.

Now i use below code finish work: ------------------------------> code start <------------------------------ rebootParams :: Params Config rebootParams = defaultParams {projectName = "Main" ,realMain = manatee ,showError = rebootShowError ,cacheDir = Just $ return "/test/Download/cache/" ,configDir = Just getCurrentDirectory ,forceRecomp = False -- don't recompile all modules, steup for recompile whole-program } rebootOptions :: Maybe [String] rebootOptions = Just ["--force-reconf"] rebootShowError :: Config -> String -> Config rebootShowError cfg msg = cfg {errorMsg = Just msg} reboot :: IORefObject -> IO () reboot ioRefObject = do rs <- rebootGetState ioRefObject relaunchWithBinaryState rs rebootOptions ------------------------------> code end <------------------------------ BTW, looks dyre don't recommand user use function `customCompile`, when it will call in function `wrapMain' always. If i just use relaunch function, i just got simple error information: "Error occurred while loading configuration file." when recompile failed. How to display detail information when recompile failed? I missing something? Thanks! -- Andy

In a test project I just created, this seems to do what you desire.

Hope this helps clear things up - Will Donnelly

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!
