In direct answer to your question, there's not a great way to step through the code. As far as I know, there isn't a way to load GHC into GHCi. Personally, I think a lot about the type-checker and so use -ddump-tc-trace a lot. You can line up the output with the code to see what is going on. Also, if you have a DEBUG build (devel1 or devel2 in build.mk), you can use pprTrace to print out from pure code.
But I surely second my colleagues in suggesting a small scope to start. My own start was in Template Haskell, which I found to be a great doorway in.

Hi,
I'm new to ghc codebase and I'm interested in stepping through the code in order to gain a better idea of how it all works.
- Is there a way to load ghc into ghci ? and debug through it ? - What are the ways experienced ghc devs step through the code ? - Any techniques you guys recommend ? - What would your advices be for a newbie to the source code ?
Thanks, Omar Mefire, _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://www.haskell.org/mailman/listinfo/ghc-devs
