Re: [racket-users] Expression-style printing and quotation: helpful or harmful?

2016-02-05 Thread Alex Knauth
I think expression-style printing is definitely helpful, but quote isn't normally helpful, especially if it's implicit like it is with vectors. The style that makes the most sense to me is the style of the teaching languages, where (list 1 2) prints as (list 1 2). If your advice is to use (lis

[racket-users] Expression-style printing and quotation: helpful or harmful?

2016-02-05 Thread Alexis King
It is my understanding that “expression-style” printing was introduced to Racket v5.0, which alters how values are printed in the REPL to permit many printed expressions to be evaluated to produce the same value. In contrast to the traditional Scheme write procedure, this tends to manifest itself a

lol. Don't be sorry. Speaking of anthropomorphization, I really love Dr Racket and hope I didn't hurt his feelings (Or is Dr Racket a she?). I employ his services whenever I can. I don't mean to be a whiner; he deserves better than that! Jon On 2/5/2016 3:44 PM, Robby Findler wrote: Sorry w

Actually you don't even have to run the program. With memory limit set to 1024, just open a file containing the expression and wait. After a minute or two DrRacket puts up a MSVC runtime error dialog. On 2/5/2016 9:39 AM, jon stenerson wrote: Setting the limit lower helped. Thanks. I did not se

It took a while for mine for the custodian limit to be reached and for the expansion to run out of memory. It may be that the threshhold for the memory use is too high on some systems. Maybe the right thing is to set the default a bit lower? Jon: if you open the "Racket" menu you should see a "Lim

On my system it behaves almost exactly as described by Jon (6.3, windows). The one difference is that DrRacket hasn't crashed yet, but the Task manager reports one processor at 100% and memory use slowly growing. Currently is at 7.5 GB. On Fri, Feb 5, 2016 at 2:29 PM, Anthony Carrico wrote:
