[racket-users] Upgrading Racket

I just tried upgrading to Racket 7 on one of my machines (macOS 10.11.6) and I get the error shown below in DrRacket. I thought I should mention it since I am probably not the only one. I installed with the obvious method, which is to just drag the new Racket folder over to applications as it

[racket-users] Re: 2018 SIGPLAN Software Award

Congrats everyone! It's a refreshing experience to see the work of people involved in not only programming, but teaching programming. You put a lot of focus on user and student experience, and have a sensibility for listening and bringing fun into programming. This creates a community and a

Re: [racket-users] 2018 SIGPLAN Software Award

Impressive and well-deserved achievement. The work done by the PLT Group and others has been undervalued for too long. I certainly believe that for too long the only marketing coming out of Racket/PLT Scheme was "it's great for education", which although it might be true, it understates its real

[racket-users] with-syntax, format-id, and ellipses

Hi, I'm trying to use with-syntax to create a series of new identifiers by breaking apart syntax and gluing bits together using format-d, but I can't get the ellipses syntax quite right. Here's my code: http://pasterack.org/pastes/81271 Line 26 contains the issue... I can't get the

The upcoming ~indexed form would make this easier, I think --- https://github.com/racket/racket/pull/2262 But for now, you'll need to expand it yourself a bit. Line 26 would be [constructors (for/list ([o (in-list (syntax->list #'(fs.o ...)))]) (format-id #'name "create-~a-~a" #'name o))]

The compiled versions of all your modules are stale. One way to fix this is to run `raco setup`. On my system I have to run it as root, but you may be able to run it as the user that installed Racket. On Friday, September 28, 2018 at 5:49:21 PM

[racket-users] Jewel is Jewelbox?

In the PLT Games included with Racket 7, there is a game called Jewel. It's very much like a game from a while back that was called Jewelbox. This was something like 20 years ago and I remember it mainly because I still have the little drawstring bag which the disk came in. It was

[racket-users] Re: 2018 SIGPLAN Software Award

Hope you get many more accolades. Your work keeps me curious & engaged intellectually long after I left programming partly due to lack of curiosity among my colleagues and my own lack of curiosity with the methods available to me. On Wednesday, September 26, 2018 at 6:53:34 PM UTC-4,
