How hard is it to make another grammar? It would be very nice if parser generators could make a page like this. Have you seen the program BNFC (The BNF Converter)? It tries to generate some nicely-formatted TeX documentation of the grammar, this could be even more useful.

It is not complicated provided that I have a nicely formated EBNF grammar to start with. I agree it would be great if parser generators do this, but there may not be enough interest and I do not have time to do it all myself. I can provide assistance and some code to start with though. Could be worth a license change too. ANTLR generated a hyperlinked grammar description when generating a parser but it does not contain the backward links. When I contacted the authors there was not really an interest there. I checked out the BNFC report. Looks interesting. Though, it was not clear from it whether one can generate hyperlinked html version of the grammar from the TeX source. Do you know it?

No worries there, if there's anything to be sorry about it's depriving people not on ghc-users of such a nifty. If you really want to apologize you could make another with the grammar of GHC Haskell :)

I added GHC v6.6 grammar. Only the syntax. Check http://www.hck.sk/users/peter/ and the notes at the end of the grammar to see what was changed. Peter.
