Language.Haskell.Parser and literate Haskell source
Hello, Are there ability to parse literate haskell source with Language.Haskell.Parser, or maybe there is some tool, which converts .lhs files to .hs ? Thanks in advance. -- Best regards, Vasyl Pasternak

You can ask GHC to remove the literate bits. I think the command is called 'unlit' but check the GHC manual to be sure. Jason
Jason, Thank you for your answer. I haven't found unliterate capability in GHC, but I found unlit function in Distribution.Simple.PreProcess.Unlit, which do the things I needed. Best regards, Vasyl 2009/4/14 Jason Dagit <dagit@codersbase.com>:

Use the haskell-src-exts package instead of haskell-src. The function parseFile in Language.Haskell.Exts will de-literate the file for you if the suffix is .lhs. Cheers, /Niklas
Niklas, I suspected that haskell-src-exts should have this function, but it was undocumented :) Thank you for the tip. Best regards, Vasyl 2009/4/14 Niklas Broberg <niklas.broberg@gmail.com>:
