Racket is such a cool project. I keep telling myself I'll find the time to do something serious with it, but I never get around to it. One minor bit of criticism - would be it be so hard/expensive to hire a designer to do some minor touching up of the DrRacket GUI? It looks like a toy, and the icons didn't even look good in 1998. I'll balance this criticism with the remark that any language/platform that manages to a…

Currently working with DrRacket 7.2 on Mac OS X. What bugs me is that everything becomes unresponsive while executing heavy stuff or code that does not terminate. The stop/kill button usually does nothing and force-quitting the app is the only option. I tried the latest Racket-on-Chez build which seems much better in this regard, but is over-all rather sluggish. Hope this will improve.

I just want to point out that you can use other editors: emacs, vim, vs code. If you really want to stay with DrRacket, feel free to open a feature request about this on the github racket/DrRacket repo.

Does anyone use this in production? Will this be a good platform to develop a DSL for a web app?

Naughty Dog uses it: slides: https://con.racket-lang.org/2013/danl-slides.pdf video: https://www.youtube.com/watch?v=oSmqbnhHp1c

I wonder how much they reused GOAL or this Racket impl. on the Crash Trilogy remake. It has always been my favorite "Lisp" game..

Currently working with DrRacket 7.2 on Mac OS X. What bugs me is that everything becomes unresponsive while executing heavy stuff or code that does not terminate. The stop/kill button usually does nothing and force-quitting the app is the only option. I tried the latest Racket-on-Chez build which seems much better in this regard, but is over-all rather sluggish. Hope this will improve.

I test drove Racket-on-Chez the other day by attempting to use the pict3d module (since 3d is an application that needs speed). My experience was as follows:

1) Install pict3d through DrRacket's built-in package manager - sudden, silent crash. Luckily I ran it from a terminal, which indicates an out of memory error.

2) Raise DrRacket's memory limit to "unlimited" and retry. Same result.

3) Google how to install packages from the command line. Wait for package to build. Build hangs during documentation. Eventually give up and ctrl-c. Hopefully it still works without docs? Racket packages aren't transactional, so every failed build leaves Racket thinking a package is installed, but it's actually broken.

4) Run DrRacket. Load pict3d and type oneliner. Incautiously press an F-key I assume will run the program. DrRacket crashes.

5) Run DrRacket. Load pict3d and type oneliner. Carefully run the program. Scene is incredibly slow but works! Then DrRacket hard crashes and locks my entire desktop so I have to go to a TTY to recover. My graphics are corrupted in a minor way. I haven't rebooted since then, and they're still corrupted.

I really, really like the look of Racket and want to use it in anger for a project, and I have a specific one in mind that would benefit from 3D, but this user experience is singularly bad. It's probably pict3d's fault, but there's no indication of this module being of "pre-alpha" stability. Or maybe it's an interaction with Racket-on-chez and C library interfacing. Let's hope it gets better.

We (https://linki.tools) use it for our main development tools product - 100% Racket in production. Check S10 (https://linki.tools/s10).

Racket is an absolutely gorgeous language. It's the kind of language that might look complicated but the important thing is to start with the basics. Yes, there are complex features in the language and big words that might be scary : continuations, impersonators, collapsible contracts, macros. However most of the time you don't really need these features.

Even the basic features of the language are enough to make your software shine. After you have a basic grasp, start to tackle other features of the language refactoring your code as you go.

Another great feature is the community. racket-users mailing list (hosted in googlegroups) is a great place to start asking questions.

You'll have a lot of fun. Enjoy your time in Racket lang. #not-a-typo

Out of curiosity, is there a particular reason you were trying to use Racket CS for this?

AFAIU typed Racket currently adversely affects performance on Racket CS (in certain cases) and pict3d looks like it's a non-base package written in typed Racket so it's likely not the best candidate for running on Racket CS right now.

You should try again from non-Chez Racket.

python comes with IDLE. Which looks dated w.r.t current IDEs. I guess for most languages, stability is the key - changing UI also means maintaining two different UIs(the old and the new)- that time could probably be better spent on language features.

DrRacket is a bigger deal to Racket than IDLE is to Python. Specifically because it provides a graphics capable REPL, which is used by a lot of the pedagogical languages and intro to programming courses that racket is perhaps best known for.

(Personally I use xrepl instead, mostly because I don't like DrRacket's text editing. https://docs.racket-lang.org/xrepl/index.html)

Actually, not using paredit (or equivalent) for editing Lisps is something I'm unable to do anymore. I sometimes use DrRacket for debugging, but racket-mode and paredit make Emacs hundreds times more efficient for me.

Is this video available without a login?

Using Firefox on Android with uBlock Origin enabled, I was redirected to some "onlinexperiences.com" site that displayed "System Check" and then a constantly growing number of lines containing only "Browser". Then I tried the stock Android Browser and it passed the browser check, but redirected to a login page. Going back to Firefox and disabling uBlock Origin, I was able to access a description of the talk and the v…

Very bizarrely for something on mozilla.org, it incorrectly believes my firefox is out of date: https://i.imgur.com/BRNBDPj.png

I think there must be a cultural disconnect between how people at Mozilla use firefox, and how users like us use Firefox.
