You looked at the source to GHCi itself I presume? It uses the GHC API, so it's a good place to start with building a variant of GHCi that uses the GHC API :-)
No. Actually, as per the wiki, I was looking at the source code to the GHC API. (Apparently there isn't even any Haddock docs, despite the requisit comments existing in the source...)
Yes, it'd be nice to have haddock docs for it.
I suppose I could have looked at the source for GHCi - but again I would imagine it's littered with error checking and other user-friendliness, rather than being written to be clearly readable by beginner hackers. ;-)
I suppose that's probably right. A minimal read-eval loop as a way of seeing how to use the ghc api would be nice.
(Also... presumably I'd have to download some giant tarball and work out how to open it. And then find the source code for GHCi amoungst everything else.)
It's not that scary :-)
BTW, you want to look at InteractiveUI.hs and GhciMonad.hs. The rest of the files in that directory belong to the implementation of the bytecode compiler, and hence are *below* the GHC API. One day we'll reorganise the sources to make this clearer. Cheers, Simon
