Hi Will,
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!

In a test project I just created, this seems to do what you desire.
Hope this helps clear things up

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!
