[racket-users] Using Chez Scheme libraries with Racket CS?

I'm new to Racket and have not yet played with Racket CS. My question is whether the Chez Scheme libraries are available. For example, is it possible to do something like (require chezscheme) and then use (fork-thread ...) to create a native thread? -- You received this message because you a

[racket-users] Automated method for making racket package installs consistent?

If I have an an install with packages X and Y installed, and a second install with packages Y and Z installed, is there a way to use raco.exe or some such to get X, Y, and Z installed on both machines without having to figure out "by hand" which packages are missing from each install? -- You

[racket-users] Problems using (debug-repl) with emacs racket-mode

I'm trying to use (debug-repl) in the following simple program: #lang racket (require debug/repl) (define (add a b) (debug-repl) (+ a b)) (add 4 5) If I run this in Dr. Racket, then I get a repl prompt as expected. However, I'm using Greg Hendershott's racket-mode for emacs, where it blo

[racket-users] Why ~a, ~s, and ~v?

I'm reading the documentation about formatted output where it says: ~a or ~A displays the next argument ~s or ~S writes the next argument ~v or ~V prints the next argument I can't help thinking these would be more intuitive if they were spelled ~d, ~w, and ~p. Perhaps I can remember them better

[racket-users] "raco pollen render" fails sporadically

I'm having an issue with getting a failure with "raco pollen render" in directory mode using a poly source file. See below for a command line history demonstrating the behavior. The call usually fails but sometimes succeeds. I have not been able to find a reliable workaround to the issue. S
