Re: [racket-users] Re: Product and Vendor ID?

Many thanks Alex, Neil. I was looking at libusb, and was hoping-beyond-hope that there might be a secret, Racket-native solution that I had never heard of or encountered. I'll be back when I'm confused as to where to put the native libs for building a stand-alone app for distribution on multiple

[racket-users] okay for the stepper to blanket disarm all syntax?

I’m in the process of trying to update the stepper to handle check-random, and I’m somewhat baffled by the amount of difficulty I’m running into in and around ‘syntax-disarm’. It occurs to me that it would probably be simpler just to walk over the expanded syntax tree and reformulate it by

Re: [racket-users] Multiple namespaces in Racket

I ended up spending the majority of my weekend working on this, and even after two days, it still doesn’t work quite right. My verdict is that it seems impossible to do perfectly seamlessly, but it seems possible (but maybe hard) to get 85% there. Here’s a (rather long) overview of what I tried

[racket-users] Re: code reflection

Hi all, Thanks to everyone who replied. I apologize for posting and vanishing ... a family emergency on Saturday took me away for the weekend. David: Thank you for the exposition about your task scheduler. I have something similar, a (thread safe) priority queue based on data/heap, although

[racket-users] Note: DB layer does not handle Pg enums

Not a critical issue, but the db package will not handle enums in Postgres. This is clear from the docs but I just now tripped over it and thought I'd raise awareness. Workaround: make the field of type TEXT and then add a table constraint: CONSTRAINT "files_current_state_cns" CHECK

[racket-users] Can anyone help me with a change?

Racket Community, We use the book Simply Scheme at my high school. Danny Yoo did a wonderful job adapting the library content for that book, but he left the code for random numbers in place. The book assumed versions of Scheme that might not have *random* and provided a fixed seed, meaning

[racket-users] Recursive Pattern Expander

Hi. I talked with Matthias Felleisen and Ryan Culpepper this afternoon about parsing recursive structures using syntax/parse. I thought I'd give it a shot, so here's what I have so far: https://gist.github.com/iitalics/fb83780fd4cd6731d6fc046fb2dbac92 It turned out to be far too inconvenient

Re: [racket-users] Can anyone help me with a change?

Hi, I think it's the case that making the change to `random` is simple (or removing it if that's the appropriate thing), though I *believe* that Danny would be the only one who could re-upload it to planet. If you're willing to get it from a different source, e.g. pkgs.racket-lang.org, then it

[racket-users] DrRacket Danish translation files?

Hello all, I was using DrRacket in Danish the last few days, and saw that various strings were missing translations. Searching the DrRacket repo on Github didn't lead me to them - where should I look to contribute updated strings? Thanks! /David -- You received this message because you are
