ghc-api

The GHC API requires that some initialisation occurs before invocation. Specifically, parseStaticFlags can only be called once. I have functions that can call runGhc :: MaybeFilePath :: Ghc a -> IO a multiple times to run some GHC API methods. However, some of that initialisation should only occur the first time that function is called. I seem to remember from Yi source that it is possible to create a global variable something like ghcInitialised :: MVar (Bool,[String]) ghcInitialised = unsafePerformIO $ newMVar (False,[]) so that in the monadic action that calls runGhc we can have (init,flags

I have a module Target , with a function Target.accessMe inside it. I compile this module in some way, then get rid of the source code. Now, what series of arcane incantations must I do to make a different program dynamically import Target.accessMe ? This program knows accessMe 's type in advance. Also, consider the fact that the source code of Target is not available. The plugins package manages to accomplish this, but seems to have serious issues with working on Windows. I've checked out plugins 's source, but am having trouble understanding it. I've tried using Hint , but can only find out

I'm working on a project for analyzing Haskell code. I decided to use GHC to parse the source and infer types rather than write my own code to do that. Right now, I'm slogging through the Haddock docs, but it's slow going. Does anyone know of a good tutorial? EDIT: To clarify, I'm not looking for something like hlint. I'm writing my own tool to analyze the runtime characteristics of Haskell code, so it's like I'm writing a different hlint. What I'm looking for is basically an expansion of the wiki page GHC As a library . Adam, this is pretty tough sledding. Ever since its launch in 2006, the
