Re: [Haskell-cafe] Re: How to make cabal pass flags to happy?

You probably want to customise Setup.lhs to use defaultMainWithHooks and add your own custom suffix handler to the UserHooks, see: http://hackage.haskell.org/packages/archive/Cabal/1.8.0.6/doc/html/Distribut... Take a look at PPSuffixHandler (http://hackage.haskell.org/packages/archive/Cabal/1.8.0.6/doc/html/Distribut...) and see the source code for ppHappy to get started I'm CC'ing Duncan, in case he has a better idea.

Hi all,

I want to do something I thought would be quite simple, but try as I might I can't find neither information nor examples on how to achieve it.

What I want specifically is to have happy produce a GLR parser from my .ly file, and I want this to happen during 'cabal install'. Which in turn means I want cabal to pass the "--glr" flag to happy during setup. My best guess is that I might want to use 'ppHappy' [1], or something in the vicinity, but there's no documentation for the combinator and it's far from obvious how to pass arguments to it.

... help? :-)

... anyone? ... please? :-)

Cheers,
