Hi,

in order to build a programming environement, it would be nice to ask the GHC about symbols etc found in a given Haskell program. I've read that GHC has a interface, which was originally intended to plug in other backends. But I've never found a detailed description or API....

Can someone help me ?

Perhaps you are talking about the external Core interface. Documentation for that is here:

http://www.haskell.org/ghc/docs/latest/html/users_guide/ext-core.html

Also, there are many -ddump-xxx options, that can give you very useful information, at any level of the compiler. Info for that is here:

http://www.haskell.org/ghc/docs/latest/html/users_guide/flag- reference.html#AEN6775

Cheers, Don

I suppose a programming environment could talk to GHCi (which provides commands like :type, :info, :browse to explore the currently defined symbols)?

I've look shortly at the GHCi documentation. So I think it would be possible to include a "GHC engine" into a IDE application by redirecting input and output from GHCi to pipes (I rembemer that emacs used something similar for doing it's compile stuff). But that's hardcore UNIX, I've forgot how to do that :-((( Greetings Hans
