[racket-users] Re: canvas% mouse event handling difference in Racket CS?

I tested with Racket v7.8 bc and it was also slow. I also tested it with a year old version of my code and added similar `time` calls around the drawing code and it behaved like the recent version redrawing for all the mouse events, only difference is that the on-paint takes around 23ms instead

[racket-users] canvas% mouse event handling difference in Racket CS?

I have a racket gui app that uses a canvas% with overridden on-event and on-paint methods. When the user hovers over drawn elements the on-paint is called via (send this refresh) to display the element under the cursor with a selection/outline. Recently I noticed that this has gotten extremely

Re: [racket-users] how to convert encoded path to something build-path can use?

Thanks! We were previously manually processing the files from current-library-collection-links, but using `links` saves ~100 lines of code. On Fri, May 21, 2021 at 11:50 AM Matthew Flatt wrote: > > Yes, the format changed in that commit. > > The `decode-link-path` function is not meant to be

Re: [racket-users] how to convert encoded path to something build-path can use?

Yes, the format changed in that commit. The `decode-link-path` function is not meant to be public, although it could be exposed. But for an approach that works now and with older versions, the API you want is `links` from `setup/link`, possibly like this: (links #:file (find-links-file)

[racket-users] how to convert encoded path to something build-path can use?

Hi, It seems that, since 8.1, the format of paths in links.rktd has changed? Are there new API fns that deal with this new kind of encoded path? Or what is the recommended way to process them? Something like this? (Is this `decode-link-path` public? I couldnt find it)

Re: [racket-users] Is there a good Racket DSL alternative to Image Magick?

I was there and, as I remember it, there was a presentation on something else where this was mentioned. IIRC, the topic was Language Oriented Programming and there was a discussion about how much complexity is okay when you are programmatically generating DSL code. The presenter mentioned
