Re: [Haskell-cafe] Hot-Swap with Haskell

Hello Andy, 2010/7/16 Andy Stewart :

There are some problems with re-compile solution:

1) You can't save *all* state with some FFI code, such as gtk2hs, you can't save state of GTK+ widget. You will lost some state after re-launch new entry.

For my 2008 GSOC application I wrote a demo app that used hot code reloading and it maintained gtk state just fine. The code (and video) is available at http://paczesiowa.dw.pl/ , it worked in ghc 6.8 and needed hs-plugins, so it won't work now, but the approach should work. regards, Bartek Ćwikłowski
