[racket-users] How to use the REPL with #lang s-exp "expander.rkt"

I'm playing around with SICP's Metacircular Scheme Evaluator, and thought it would be convenient to try and do that in a #lang setup in Racket, so I can use the Racket Definition Window and REPL. No Reader modification is needed, since Scheme code is already S-expressions. The expander just

[racket-users] Re: Beautiful Racket v1.0

Congrats! I've gone through all the chapters and it has been the most entertaining programming book I have ever read. It's been practical, too, as I have already used bits of it in a medium-sized (first) Racket project. I would gladly buy it and will recommend it to many of my co-workers.

[racket-users] minimal vs full racket performance issues

Hi - (This is a continuation of some discussions I've had on the dev list a couple years ago.) We continue to have performance issues stemming from Racket's runtime file system usage. Hopefully someone can shed some more light on the issues so we can adjust our usages... We use a minimal

Unfortunately, I don't think there's an analogue of apt autoremove, so you probably have to do it manually. On Thu, Mar 16, 2017, 6:37 PM Dan Liebgold wrote: > On Thursday, March 16, 2017 at 3:30:56 PM UTC-7, Sam Tobin-Hochstadt wrote: > > Just installing

Won’t raco pkg remove and raco pkg empty-trash do the trick? Ed > On Mar 16, 2017, at 3:42 PM, Sam Tobin-Hochstadt wrote: > > Unfortunately, I don't think there's an analogue of apt autoremove, so you > probably have to do it manually. > > > On Thu, Mar 16, 2017, 6:37

Just installing rackunit-lib will avoid the docs and tests, which should substantially reduce the footprint. Sam On Thu, Mar 16, 2017, 6:25 PM Dan Liebgold wrote: > Hi - > > (This is a continuation of some discussions I've had on the dev list a > couple years ago.)

Re: [racket-users] minimal vs full racket performance issues

`raco pkg remove rackunit && raco pkg remove --auto` should do it. Vincent On Thu, 16 Mar 2017 17:42:23 -0500, Sam Tobin-Hochstadt wrote: > > Unfortunately, I don't think there's an analogue of apt autoremove, so you > probably have to do it manually. > > On Thu, Mar 16, 2017, 6:37 PM Dan

Ah, I didn't even know about --auto. On Thu, Mar 16, 2017, 6:48 PM Vincent St-Amour < stamo...@eecs.northwestern.edu> wrote: > `raco pkg remove rackunit && raco pkg remove --auto` should do it. > > Vincent > > > On Thu, 16 Mar 2017 17:42:23 -0500, > Sam Tobin-Hochstadt wrote: > > > >

Re: [racket-users] How to build new formlets that allow passing default values (such as hidden)?

Thanks Philip. I checked out the links, but I fear that it's over my head, and that I would almost surely screw it up. For now I'll keep passing the parameters. Cheers, Marc On Tuesday, March 14, 2017 at 3:22:39 PM UTC-4, Philip McGrath wrote: > If you want it to be part of the continuation

Re: [racket-users] Beautiful Racket v1.0

This is wonderful. I have not read through everything, but the bits that I have read are well-written, insightful, and fun. I don’t know if a book like this is enough to get people interested in building DSLs, but if it isn’t, I’m not sure what is. I’m a tiny bit sad (or should I say “bummed
