Yes racket mode is installed. A few other odds and ends as well. A few other people direct responded some other suggestions. I would suggest they add them to the whole group as they might prove useful for others. Ken On Sat, Nov 05, 2016 at 01:58:48PM -0400, Ben Greenman wrote: > Do you have

Hi, I put Racket on different computers and tablets. So my 7" tablet receives a copy fo Racket :) But: The pdfs of the documentation have a wide blank border and a ratio aspect, which is different of that of the tablet. When viewing the pdfs with mudf, it (mupdf) tries to disply "the whole

There's no official package. It's probably best to just dump the contents of this file into the existing one. Btw, I think this file should probably not belong to "gui", but it may be cumbersome to move it to a different place I guess. On Sat, Nov 5, 2016 at 3:49 PM, Robby Findler

Re: [racket-users] Extending DrRacket's LaTeX Shortcuts

I think it would be great to adjust the one that DrRacket uses to use this one. Is that in a pkg somewhere? Or would it be better to just drop it into the existing one? Robby On Sat, Nov 5, 2016 at 7:31 AM, Laurent wrote: > This may be of interest: >

Hi David, thanks for your reply ! :) SUPER! THAT helps! Is this kinda "pattern", that if 'function' does something once, there is a 'function*' that does the same thing multiple times? Cheers Meino David Storrs [16-11-05 14:37]: > (regexp-match* #px"(AA.+?AA)"

Re: [racket-users] The regex and me...

(regexp-match* #px"(AA.+?AA)" str) regexp-match* matches multiple times through the string. As with Perl and pcre in general, a trailing '?' makes quantifers non-greedy. On Sat, Nov 5, 2016 at 8:59 AM, wrote: > Hi Jens, > > thanks for your reply! :) > > ...hmmm...I

So as much as I know there is much love for Dr Racket, I am not the biggest fan. Yes I must admit some of its helper features are great for working in racket and if I must debug something it is probably the best place to work. Anyway was wondering what other editors people use. I have been a
