#10153: GHC mode for converting files to explicit layout -------------------------------------+------------------------------------- Reporter: ezyang | Owner: Type: feature | Status: new request | Milestone: Priority: low | Version: 7.11 Component: Compiler | Operating System: Unknown/Multiple (Parser) | Type of failure: None/Unknown Keywords: | Blocked By: Architecture: | Related Tickets: Unknown/Multiple | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- One area where GHC is a little less friendly to newcomers is its Byzantine whitespace layout rules. Once you've gotten used to using GHC you can usually get what you want by abiding certain style, but before then it might be useful to see how GHC is inserting semicolons to your document. I don't think this would be too hard to do. The idea is to get the token stream and look for virtual curlies with no location. Once you have a list of them, you can go over the original buffer again and insert a brace or semicolon whenever you see a token like this. Might be a good beginner task. This function would also be useful for debugging layout, since knowing if semicolons are being inserted is useful. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10153 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
