Dear GHC developers, I'm developing a framework for development tools for Haskell. I use the GHC API to parse and typecheck the source files. I recently started to work on a quick-fix (automatic program correction) for Haskell source code (correcting parenthesis problems, like 'putStrLn "xxx" ++ show a' ==> 'putStrLn ("xxx" ++ show a)'). To do that I need to get the typed syntax tree even if the program contains type or rename errors. I could only do this by a nasty hack, adding a new TH module finalizer (tcg_th_modfinalizers) to extract the type checker's state before it fails. Is there a "correct" way to do this? I would not like this refactorings to be unusable if the GHC API changes. By the way, if you know of any similar attempt please let me know. Sincerely, Boldizsár Németh haskelltools.org
