Hello everyone,I'm interested in writing the API-tracker described here http://hackage.haskell.org/trac/summer-of-code/ticket/1565 Mr. Marlow suggested I discuss it on the mailing list first. If this is the wrong list, I'm sorry, and I'd appreciate knowing where to find the correct one.
Excellent! (you could also try [email protected] , which contains more people)
From the package versioning policy herehttp://www.haskell.org/haskellwiki/Package_versioning_policy it seems like the most foolproof way to validate a revised module's version number would be to diff the types of each exported symbol. There's a previous thread on this list by Laszlo Nagy suggesting
Can you link to it in online archives?
has the information I need to answer that question, or at least to read the GHC API reference. Unfortunately---you guessed it!---I don't know enough to understand the commentary.
hmm, I had this issue a bit last year, working on Haddock! But I eventually got used to it, by trying to do things with it. I found it's important to also go read the GHC code itself. Often it contains comments that didn't make it into the generated Haddockumentation; sometimes reading a function's implementation is necessary to guess what it does. Maybe you could find another project that uses the GHC API on types, and try to understand it? (for example, Haddock's code breaks up some version of the types in order to display them in docs, although I suspect it may be a less-processed, closer-to-source-syntax version than you'd want for actually comparing two types with each other). etc... And the Commentary is pretty good once you know enough (and some of the pages are overviews of the compiler pipeline...)
and for ghc-specific questions, [email protected] (or [email protected] sometimes for technical GHC-internals is alright)
also, just lurking and reading relevant mailing-lists where other people are trying to solve their own problems relating to GHC: sometimes this helps :-)
