[racket-users] Typed Racket and struct

Hi, I've been using Typed Racket in the last few months and it has been an interesting experience. However, there are a few helpful features of "normal" Racket that are not yet available in Typed Racket. One of them is the ability to use #:constructor-name in struct type definitions. I used

Re: [racket-users] Help updating racket/function

Ah, that’s my package, and that issue is my mistake. I had a version exception for 6.2, but I was missing a version exception for 6.2.1. It should work on 6.2.1 now. Try updating alexis-collections (or uninstalling/reinstalling it), and it pull the right version. Thanks for the report! Alexis

[racket-users] Help updating racket/function

I installed the package alexis-collections via DrRacket. The build process reported problems with an unbound identifier, and after investigating I found that my installation's racket/function module is missing a couple of things that are in the current version on GitHub. However, DrRacket

[racket-users] Rust vs. C as a complement to Racket?

The more I dig into Racket, the more I like it. It seems like a perfect fit for both my personality and the type of applications I am, and will be, writing. For the vast majority of what I need to do, it's a great fit. I do occasionally encounter a need for raw speed, so I'm looking for a

Re: [racket-users] Rust vs. C as a complement to Racket?

Brian, -- when you say "raw speed", do you need "Fortran" level speed for numerical algorithms or just "somewhat faster than Racket, almost close to C"? If it's the latter, Rust may work out for you. -- when you say you need many cores for your computations. That sounds like very-raw

[racket-users] Re: Configuration Files

I appreciate all the responses. Time to do some reading and experimenting. At this point I've managed to read files and use regex to pull data into new variables or parameters I've set up, but I haven't gotten to the point of actually reading in racket data structures, so this gives me an angle

Re: [racket-users] Configuration Files

Yes, I like the idea of #lang info(#lang setup/infotab) which is highly constrained, and it is an out-of-box solution. It's better to have a (get-info/file filename.rkt) as an alternative to (get-info/full infodir-path). On Thu, Nov 19, 2015 at 7:32 AM, Neil Van Dyke

Re: [racket-users] How to get information about where an error occurs, in a stack trace context?

I have a related question. I turned on error trace using the command line Robby suggested, but it doesn't give me a trace, but rather just the call point and error function. Here is an example, the trace should be f -> gg -> g -> hh -> h then bang, the error. But instead Racket shows me f
