I've done no math in 20 years - used to do tons (with the not so great graphics of the time) saw this intriguing plot & banged my head against a wall for a couple of hours. Then I just settled down & read the manual systematically, pretending it may have some info, followed the examples and

[racket-users] running tests with different #langs

I frequently want to run the same tests with different #lang's. Has anyone written a test harness that lets me do this without duplicating the test code? (I couldnt find anything on the pkg server.) -- You received this message because you are subscribed to the Google Groups "Racket Users"

OK, I am a bit of an idiot, but in case someone else reads this thread looking for answers, here are the resolutions I've chased down so far. 1. **I did not read the docs for pdf-read well enough** because right there at the top of the main page, it says it only works on Linux and macOS.

SHORT: You may wish to *look* at the first units paper at https://www2.ccs.neu.edu/racket/pubs/#pldi98-ff because what you describe is almost exactly the example from that paper. Just read the example section. If you like what you see, jump into the docs. ;; - - - SOMEWHAT LONGER:

hmm... I've tried to see what dependencies would dumpbin show on my machine for libpoppler and it fails with "e:\libpoppler-glib-8.dll : warning LNK4048: Invalid format file; ignored" so it may be that something is wrong with a binary on Windows 10. Still my previous advice (ignore anything

[racket-users] Re: error with pdf-read / libpoppler on Windows

That's why I actually prefer dumpbin (see the other thread) from depedency walker - simpler without so many confusing details. But since you probably don't have VS here is my advice: collapse entire result tree from dependency walker - leave only top level libraries to see which ones are

[racket-users] Splitting up a GUI source file?

Hello Racketeers, I am trying to create a GUI program, my problem is that the source code for the GUI portion is growing out of control and I don't know how to split it up. Here is some background info: the GUI is basically just a specialised frontend to a database, the users clicks some

Re: [racket-users] Windows Foreign Libraries

Another option to check for dependencies (if you have Visual Studio installed - VS community edition is free but BULKY) is to run dumpbin from console, or better yet VS code since dumpbin is in VS/bin folder. It is less overwhelming but will check only for one level deep dependencies, ie you

This point is well taken. For my package's core functionality I mainly need to be able to get a page count and the size of the first page. I would rather not have to try and write my own functions to do that; even though it looks (from the docs you provided) like the parsing wouldn't be too

Really silly question but I was using the rsvg package with racket/gui on Linux and everything was working fine. I moved the code over to windows to try it out (after installing the rsvg package there) and it's complaining that librsvg-2.2.dll is missing. I've now tried two separate .dll
