helper tools for reading haskell source
Hey, Often, when I read haskell code, I would like to know how and where a datatype or function is defined. Normaly I read the code of package, and I then use grep. But when it is not defined in the same package, grep can not help me. Example: I want to know where the datatype Frame and the function windowGetChildren in the wxHaskell odule are defined. I know there is hoogle, but for these it was unable to help me (or I was unable to use it correctly?). So I was wondering, what other tools or methods do you use to "analyse" haskell source? Regards, Nathan

windowGetChildren is defined in wxcore, so you have to enter windowGetChildren +wxcore in the Hoogle search field Regards, Henk-Jan van Tuyl -- http://Van.Tuyl.eu/ http://members.chello.nl/hjgtuyl/tourdemonad.html Haskell programming --

Also, it’s useful to know that hayoo has access to many more packages then hoogle, so I mostly use hayoo now. Also, EclipseFP and Leksah can give you this information with a key press or even just hovering the mouse over a function. best, Miguel

If you're able to compile the code, you can also load its file in ghci. Then :i will tell you what module defines a symbol. -- see shy jo
