Re: [Haskell-cafe] HTML framework for web-ui

Hi Heinrich, Looks simple and interesting. I browsed the git, but not much docs yet. Just examples, or have I looked at wrong places? I see that API is still under heavy design. When do you expect the API might stabilize? (BTW, examples in Readme do not work.) vlatko Vlatko Basic wrote:

constraining it to >= 1.17 would be better while 1.18 isn't out yet.. On Thu, May 23, 2013 at 1:42 AM, Roman Cheplyaka wrote: > Perhaps I'm missing something, but why not just > > cabal-version: >=1.18 > > ? > > It will constrain the Cabal version, not cabal-install, but judging from >

Re: [Haskell-cafe] How to throw an error if using "cabal-install" < version XYZ?

Perhaps I'm missing something, but why not just cabal-version: >=1.18 ? It will constrain the Cabal version, not cabal-install, but judging from the fix[1] this is what you actually need. [1]: https://github.com/haskell/cabal/commit/d148336e97cda2e3585c453cf9af61bc3635131a Roman * Ry

Hey Ryan, I ran into a related issue, heres a a way you can do this safe IN the cabal file (or at least you can modify my hack for your purposes) heres a link to the workaround I did for making LLVM-hs work across >= 1.17 and < 1.17 cabal, but you could abuse it to make sure setup.hs barfs on old
