Make, in place build, was Re: [racket-users] Racket v6.2

I did a 2 character change to Racket (see https://github.com/plt/racket/pull/1045), and hit make. This failed to build, I guess because of package mismatches, so I pulled and tried again, which failed. Also, my laptop is very slow for this kind of thing, so I did a fresh clone and in place build on

Re: [racket-users] Racket in a web page (via Whalesong)

Hi Anton, There has been some work to make Whalesong self-hosted. I'm not sure if it works as I didn't try it. There are some language incompatibilities but your Racket code will just work otherwise, notably Big Bang programs. Whalesong doesn't give you a REPL, but it will show you stacktrace

Re: [racket-users] Racket in a web page (via Whalesong)

Anton, Vishesh Yadav has been doing some pretty cool things with Whalesong lately, notably to make program sharing easier[1]. Vishesh will be speaking about this work at RacketCon on the 27th. If you can't join us in person, the talk will also be streamed live and recorded. Vincent [1] https:/

[racket-users] Racket in a web page (via Whalesong)

Hi, Does anyone use Whalesong to script web pages? As far as I understand the Racket design, Whalesong is enough to bootstrap full Racket in a JS environment. It's a great opportunity. I would like very much to have an interactive lisp development where I can develop both server side and clien

[racket-users] Racket Language Track for Exercism

Hi all - I'm adding Racket to exercism.io: http://exercism.io Basically, Exercism is an app where users submit solutions to problems, and receive feedback for said solutions. Exercism currently supports 26 languages, with a minimum of 10 exercises for each language. Most, if not all, languages

[racket-users] Racket 6.2 consumes 100% CPU when run without a terminal

I meant to start DrRacket, and typed "racket" in the GNOME command-launcher. Nothing happened and I forgot about it. The next morning, I find my computer sluggish, and one reason is that Racket is occupying one of the cores at 100%. -- http://rrt.sc3d.org -- You received this message because y

Yes, it is already included in the .gitignore file. I guess I meant it's not special to _Racket_, but it is useful to have a convention for stuff like git and helping others. :) Jay On Tue, Jun 23, 2015 at 11:30 PM, Matthew Butterick wrote: > PS The 'extra-pkgs' directory is a tiny bit special:
