Get module contents

Question

The :browse, :info and :type GHCi commands are very convenient.

Is it possible to get the same information programmaticaly in a Haskell program? That is, to get the exported functions from a module, the types of stuff, etc.

Answer 1

:browse - when a Haskell program is compiled, no (useful) information is kept about which module something came from, so your program wouldn't be able to access that information.

:type - Unless you're using Data.Typeable, types aren't visible at all at runtime. Types in Haskell are mostly for the compiler to check to correctness/safety of code.

:info - See above.
