Re: [racket-users] [racket] Racket 6.3(.0.7) breaks old code

Thanks for the example! The problem is a bug in `namespace-mapped-symbols` (due to changes related to the new macro expander). I will push a repair later today. At Mon, 30 Nov 2015 20:16:44 +0800, WarGrey Gyoudmon Ju wrote: > Thank you, Matthew. > > The project itself is organized as a multi

[racket-users] reducing pauses with incremental GC

The development version of Racket now supports an incremental garbage-collection mode that can eliminate long pauses in a program. For example, incremental mode is useful for avoiding pauses in games and animations. For more information, see http://goo.gl/rYjTIi You can try out incremental

[racket-users] Help with a bewildering bug.

I've been working on a new feature for Heresy and I've run into a bug I cannot even begin to track down the actual cause of. There's a Github issue here: https://github.com/jarcane/heresy/issues/37 I've tried a few naive solutions, but to be honest I really don't even know where to start because

As a follow-up for the list, it looks like the issue was resolved following a discussion on the github issue. Vincent On Wed, 02 Dec 2015 03:25:55 -0600, John Berry wrote: > > I've been working on a new feature for Heresy and I've run into a bug I > cannot even begin to track down the actual

Ah, right: that code didn't actually save the bitmap itself. How do you like this code? Robby #lang racket/gui (require (prefix-in - racket/base)) (provide (rename-out [image-data-snip-class snip-class]) image-data-snip%) (define image-data-snip% (class image-snip% (inherit

[racket-users] Windows show-scrollbars forcing call to on-paint

Short version: show-scrollbars seems to be forcing my canvas object to call on-paint. The problem is that on-paint contains calls to show-scrollbars and thus creates an infinite loop. Long version: I have a canvas that displays an image and will enable or disable the scrollbars based on how

Re: [racket-users] reducing pauses with incremental GC

Wow, this is great. I just tried it with one of my games that I made with big-bang, and the pauses I was having are completely gone, as far as I can tell. (I was doing quite a bit of copying, so I think the GC was triggering fairly often.) Thanks a lot for this; it’s definitely a big

Thanks: I've pushed the syncronization code to the handin repo. And yes, you're right that `thread` (which is what I think the handin server uses) doesn't make use of multiple cores. Places sound like the right construct to use here, but I can already predict one problem: 2htdp/universe depends
