#4836: literate markdown not handled correctly by unlit ----------------------------------------------+---------------------------- Reporter: guest | Owner: Type: bug | Status: new Priority: low | Milestone: 7.6.2 Component: Compiler | Version: 7.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects valid program | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: #7120 ----------------------------------------------+---------------------------- Comment (by elliottt): I've had success using this with octopress, with this page as an example: https://github.com/elliottt/elliottt.github.com/blob/source/source/_posts/2… -serenade-in-haskell.markdown I used ```haskell as the starting block, so that github would highlight the haskell blocks, though ``` also works. Do you know if BlogLiterally will process the fenced code blocks? I know that pandoc is happy to process them, so I figured that it should just work with anything that depends on that. Additionally, bird tracks in markdown are for quoted blocks, not code, so if that's how BlogLiterally is expecting to find the code, that could be a problem. Does BlogLiterally process .lhs files? If so, that could also be a problem, as markdown processing requires the .md extension, instead of .lhs. The reason for this is that .lhs processing allows CPP macros, but in markdown the # means a section header. The different extension signals different flags to unlit. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/4836#comment:15> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
