[racket-users] GUI executable creating an annoying command line window

2020-05-26 Thread Philip Benade
Hi All I have been trying to create a simple GUI with the racket/gui library. For the most part it works but alongside my GUI it also creates a command line window. You can see a screenshot of this in the attached picture. I found this discussion when I searched for a solution:

Does it change anything if you use #lang racket/gui instead of #lang racket (require racket/gui)? On Tue, May 26, 2020 at 10:00 AM Philip Benade wrote: > Hi All > > I have been trying to create a simple GUI with the racket/gui library. For > the most part it works but alongside my GUI it also

I cannot reproduce this. If I create the executable from the command line using "raco exe --gui work-timer.rkt", or from DrRacket specifying GRacket as the "base", the console window does not show up. If I create the executable using "raco exe work-timer.rkt" or by specifying "Racket" as

Hi Alex I managed to get it working. Updating Dr.Racket to 7.7 did the trick. I should have thought of it sooner, but I became so wrapped up in looking for the problem in my code I didn't think of it. Thank you for your help. Regards Philip On Tuesday, 26 May 2020 11:50:58 UTC+2, Alex

It might be easiest to just use the `image?` predicate from inside the sandbox. Get it out the same way you got the image itself out. Robby On Tue, May 26, 2020 at 6:22 PM Stephen Foster wrote: > The following returns #f and #t. How can I get it to return #t and #t? > > Context: I want to

The following returns #f and #t. How can I get it to return #t and #t? Context: I want to allow students to run Racket code on my server. But when I sandbox their code, I am getting back something that doesn't behave like a 2htdp/image object. I'm not exactly sure what it is. #lang racket

Hello, searching through a bunch of different packages I noticed that the code/download links are quite inconsistent. For some packages there is a download button clicking that button does nothing (in firefox) because it contains a git:// protocol url, here is an example package:

I think the best way to implement what you describe for a "better version" is as follows: Expand `(instance h1 half-adder-arch)` into something like (define-syntax h1 (half-adder-arch-info)) Where `half-adder-arch-info` is an expansion-time structure describing half-adders. Then the `assign`

Okay, I could just be putting my foot in my mouth, here, but it sounds like you’re describing the kinds of things that are typically done by a type-checker. Have you considered adding a type-checking pass? It would contain an environment that maps names like “h1” to “types” that indicate that

I am personally confused about what you think the problem is, so I just want to make sure that you know that you can develop and test a new package, or you can modify an existing package and test the modifications, without publishing the package. Basically in Racket you can: * create a new
