Re: [racket-users] [newbie] Help with streams

My “collections” package makes fairly heavy use of streams, so it provides a number of utilities to help with what you want to do. The obvious function here would be `generate-sequence`[1], which creates a stream from a generator. You can call `take` on the resulting sequence, since my generic impl

[racket-users] [newbie] Help with streams

Hi, there. I have just started playing with Racket and would like some help with using streams/generators (I am not particularly versed in programming in a functional style and am attempting to learn :-)) So I have a function called (new-name) that creates a random name, like "Bob Brown" or "

Re: [racket-users] backwards incompatible change to redex: does it break your models?

The reason the "E_1" and the "e_1" are treated differently is that the "e" is mentioned in "binding" position of the shortcut. That is what makes it special. Does this make sense? (Have a read of the paragraph in the redex docs for reduction-semantics that talks about shortcuts and let me know if i

Re: [racket-users] Advent of Code

I like yours better. I wrote mine that way because I thought there were going to be feedback loops and I had to run to a fixed point, like real hardware. But it never seems to generate circuits like that. On Sun, Dec 20, 2015 at 9:14 PM, Matthew Butterick wrote: > An adaptation of Jay's solution

Re: [racket-users] Advent of Code

An adaptation of Jay's solution that turns every wire into a function that you can evaluate in the REPL. Plus: shorter. And dumber. Or cleverer? Thin line. https://gist.github.com/mbutterick/bc24a6291081b1ce0f31 On Saturday, December 19, 2015 at 11:53:52 AM UTC-8, Daniel Prager wrote: > Thank

Thanks guys for such a quick response on Sunday! To clarify - the mix problem was definitely the case the first time I tried and I was under the impression it was the original - Neil's repo installed from the package. The updated repo (Jay's) simply crashes GUI whenever code is executed so it may

Thanks Greg. I fixed the issues problem. I'm still working on the mix problem. (It doesn't happen on my laptop, so I need to develop with a different machine to test it. I have one available but it is not convenient to use.) Jay On Sun, Dec 20, 2015 at 4:54 PM, Matthew Flatt wrote: > Thanks for

Thanks for the report about the "Remove" button in the "Available for Catalog" panel! I've pushed a repair for the next version. Meanwhile, the "Currently Installed" panel provides another view on installed packages, and the "Remove" button there should work. I think Jay is working on the "mix" p

[racket-users] How to cite Racket in a journal paper?

Hello, I am writing a paper for a scientific journal. The results that I am presenting there were obtained mostly in Racket. What is the best way to give credit to Racket in references? Is there a specific paper I can reference, or just link the website? If specifics matter: I am heavily usi

Re: [racket-users] backwards incompatible change to redex: does it break your models?

I noticed this last week when I upgraded Redex for other reasons. It broke one of my models, and I was momentarily confused. In fact, I took the error message to mean I had somehow introduced an error and spent some time staring at my tests to see if I had introduced a syntax error. I only fixed th
