Re: sharing datatypes : best practice ?

i ve developped a datatype in a module P, and another module will use it, and most probably a few others, and its quite central to the apps Im building.

what is the best organisation ?

-import module P everywhere - isolate this datatype in a module, which would be imported everywhere ?(very "include like") - merging the module around this datatype ?

this last option is not a good option here as : - this would be too big - P is generated by Happy.

Hi Luc, Isolating the datatype in a module is what I always do. Only "Main.hs" calls the happy parser and just about every module uses the datatype, so it makes sense to separate them. Jan
