#10869: Option to dump preprocessed source -------------------------------------+------------------------------------- Reporter: phischu | Owner: Type: feature | Status: new request | Priority: low | Milestone: Component: Driver | Version: 7.10.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -------------------------------------+------------------------------------- It would be awesome if GHC had an option `-ddump-preprocessed` that dumps the source code for each module after preprocessing. I am not sure what the current definition of "preprocessing" is but I mean the output of at least the following tools: happy, alex, c2hs, hsc2hs and cpp. Additionally even if a module was not subject to any preprocessing it should be dumped anyway. Use case: I want to parse module files from packages from hackage with `haskell-src-exts` but find it prohibitively difficult to get the preprocessing right. The idea is that after `cabal install` with ghc options `-ddump-preprocessed -ddump-to-file -dumpdir real_modules` you get a complete working set of haskell modules that can be parsed directly without any preprocessing in folder `real_modules`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10869 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
