[racket-users] Re: Is there a webview for Racket?
Neil, Thanks a lot for the detailed response. I am new to Racket, FFI and everything else but I decided to take a shot at it today. I've managed to create a web-view% GUI class that can display web pages on macOS. It is wrapping around WKWebView which is the current way of doing things. I haven't programmed in Objective-C in 16 years, so I a bit over my head here. I've uploaded it to: https://github.com/soapdog/racket-web-view I don't yet feel that it is ready for the package catalog. I need to fix many things and I'd really welcome help from people who know the current Objective-C way of doing things. WKWebView relies a lot in properties and I can't find a way to deal with them. For example the "delegate" in the code in the repo is not working, nor is the retrieval of the current URL (which in Objective-C should be as simple as "webView.URL") Anyway, it is a first step towards a real Web View for Racket GUI. It can already load pages and navigate, so it is not completely broken. This is my first FFI project and also my first Racket code after doing Beautiful Racket, it is all brand new to me. Sorry if I'm not idiomatic. I'd really like feedback, advise and help with this. All programming ecosystems benefit from having Web Views. I hope this becomes my first contribution to Racket. I also need to do Windows and Linux, but one lion at a time... Cheers andre PS: I tried posting this message a couple times but it was not getting through...

Re: [racket-users] What is a (the?) way to track requirements for a web or app with Racket?
I've found Greg Hendershott's Makefiles to be super helpful with this
https://www.greghendershott.com/2017/04/racket-makefiles.html
I use that article as a base and then make mods, such as this
