Re: Fastest way to reload module with GHC API
Yes, thank you Simon, my test works if I wait at least 1 second before the
two loads, so I'd say I run exactly into that issue. So I can adapt my code
to only remove the target if the files do not give me a time difference.
Thanks a million!

I have a file whose path is fp
I load the module with:
addTarget Target { targetId = TargetFile fp Nothing,
targetAllowObjCode
= True, targetContents = Nothing }
Then I load the module
load LoadAllTargets
And when I want to reload the module (the contents of fp have
changed) I do:
removeTarget (TargetFile fp Nothing)
load LoadAllTargets
and then I rerun my initial code (addTarget, load)
You should be able to just invoke 'load LoadAllTargets' and omit the
intermediate remove/load step. Or is there a reason you want to
remove the target?
