Hello I've a Frown port of the c2hs parser here: http://slackwise.org/spt/files/Haskell/lang_c-2007_05_21.tar.gz I've also done some work towards packaging the original c2hs code so it follows the form of the Language/Haskell library (removed the 'C' prefix from file names, added Haddock markers in some of the comments). Other changes include some work to handle GCC attributes (added in the syntax tree and some of the productions in the parser); and some work on a pretty printer (there is a rough version implemented with UUAG and the PPrint library that needs better parens handling). Also I've changed the AST slightly to remove some of the dependency on c2hs - the parser just tracks source position rather than source locations and unique names. I haven't looked further at disentangling the Happy parser, and with the changes to the syntax tree and file layout it would need some work to reinstate it. I hope to look at this in the next couple of weeks. Best wishes Stephen Tetley Duncan Coutts wrote:

* The parser error messages are terrible (it might be interesting to try porting from happy to frown for this purpose)
