Hi,

Is there a gui library written in haskell (based on purely functional concepts)?

Emanuel

See the "High-level" part of http://www.haskell.org/haskellwiki/Applications_and_libraries/GUI_libraries Many are not currently developed anymore though. I find reactive-banana together with wxHaskell to have a quite “functional” feel to it, might be the best option currently. best, Miguel

I'm looking for a library written from scratch in haskell, not high level bindings.

Nobody's going to reimplement an entire graphics stack in Haskell (or any other language, except as a tour-de-force with no practical use); they're going to use existing bindings to a well-tested existing GUI. Rewriting Wx or Gtk+ in Haskell, seriously? Aside from the effort required at the outset, try keeping up with changes to the thing you're reimplementing. Not maintainable and not viable. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net

Java did it. Swing just asks the OS for a window and draws in it. Works fairly well...except that a Java (Swing) program never quite acts like a Windows, Mac, or Linux program.

And there was a practical use: you got much closer to "write once, run anywhere" whereas the earlier AWT resulted in "write once, test everywhere".

The same could be done in Haskell, but it would be a huge time commitment.

That's exactly what i'm thinking about (and QML/Qt). Emanuel

Are you kidding? Swing is a dream. Ever spent time with MFC? Get real On Feb 7, 2013, at 10:59 AM, Brandon Allbery wrote:

It did indeed. I can tell you've not spent much time with the folks who have to deal with the result. AWT/Swing is exhibit A for why nobody else does it that way.

That's a good reference, but what I am exploring is a quick, draconian solution that will give me an extremely conservative set of packages that are not interdependent in any way. It seems that such a program does not yet exist, but should be straightforward to write, joining HackageDB dependencies against packages in the platform. The best I've got so far is to scrape results from cabal info, but I'm looking for a more efficient set of API's to solve the problem. Does the Haskell Platform come with modules that support this sort of API? Cheers, d On Thu, Feb 7, 2013 at 4:53 AM, Richard Norton wrote:

Is there a list of hackages available that *only* depend on the latest Haskell Platform?

-or-

Can such a list be reasonably generated?

-or-

Will there even be anything left after the hackages are filtered?

This project seems related:
