Indeed, that's what I forgot to mention, Resharper in Visual Studio 2005 does that for C#, IntelliJ & Eclipse for Java. You rarely need compilation, its syntax checker runs inplace and incrementally and shows you the errors and warning in the right margin. That saves you a lot of time. For Haskell, the Eclipse plugin should do something like that, at least every time you save. http://eclipsefp.sourceforge.net But I never got it to work with GHC (only GHCI/Hugs), I tried on 3 different machines (on Windows). I also guess this should not be too difficult to implement in Emacs... for someone how knows Emacs that is. -----Original Message----- From: haskell-cafe-bounces@haskell.org [mailto:haskell-cafe-bounces@haskell.org] On Behalf Of Christopher Lane Hinson Sent: Sunday, June 17, 2007 12:15 AM To: haskell-cafe@haskell.org Subject: Re: Re[2]: [Haskell-cafe] IDE? While we're on the topic of IDE features. I wish to have an editor that ran GHC[I] every few seconds or so, and underlined sites of syntax errors in red. This would save me a lot of back-and-forth. If an editor did this, I would switch (from kate) in a heartbeat. This has been mentioned before in only one place that I can find: http://compilers.iecc.com/comparch/article/99-09-067 Yeah, I could do it myself. --Lane _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
