Re: [racket-users] What has happened to extflonum support in 32-bit nightly builds?

Matthew, unsafe-extfllong_double_mult: unsupported on this platform FWIW, my actual program is a C program that uses a Racket library obtained with raco ctool. I can provide you more details and a reproducible example if the above is not enough to hunt down the cause. I think the problem is

You can set up a package, as opposed to a collection, with `raco setup --pkgs liquid-extensions`. Sam On Thu, Nov 12, 2015 at 2:27 AM Alex Knauth wrote: > As far as I know, raco setup doesn't deal with packages, but with > collections. Assuming the `liquid-extensions`

Re: [racket-users] Mandatory arguments for command-line

Thanks, Greg, that's helpful. By the way, I love racket-mode. DrRacket is a great environment, but I get frustrated editing text in anything but Emacs (or more recently Emacs with Evil via Spacemacs). Racket-mode provides enough support that I only switch into DrRacket when I've hit the wall with

Re: [racket-users] Mandatory arguments for command-line

I don't know how to make the `command-line` syntax do this (there's no flag-clause like `#:required-once`). So I think I'd just do a normal test outside it: (define destination (make-parameter #f)) ;default to #f meaning "unspecified" (command-line your existing code ) (define (main)

Re: [racket-users] How to "strip" a package installation with "raco pkg install"

Splitting "foobar" into "foobar-lib", "foobar-doc", etc., certainly solves the problem, and that approach is used widely for packages in the main distribution. It's also kind of a pain, though, and `--binary-lib` is intended to be a more automatic solution --- with the trade-off that built

Re: [racket-users] Feasibility of Racket for scientific and engineering calculations

Hi Marc, Take a look at: https://github.com/soegaard/racket-cas Start with the readme and play with a few examples. Skim (later parts) of: https://github.com/soegaard/racket-cas/blob/master/racket-cas/racket-cas.rkt to see what's implemented. Any bug reports and comments are welcome.

[racket-users] Mandatory arguments for command-line

I've just ported a small sript to Racket to investigate Racket as a scripting language for cli tasks. (My past Racket experiences have really only been with the HTDP languages.) I was quite happy with the process and the results, but I have one question I haven't been able to figure out on my own:

Re: [racket-users] What has happened to extflonum support in 32-bit nightly builds?

The more interesting thing is that the 'longdouble.dll' is not put into the runtime directory by 64-bit Racket, too. Still, the 64-bit program works without any additional effort. Oops, sorry, I just checked again, the 64-bit Racket fails too. I think you'll need to call

Re: [racket-users] Feasibility of Racket for scientific and engineering calculations

Since you mention symbolic computations: is there anything that does symbolic differentiation in Racket - I know Maxima is written in Common Lisp. I would I would be happy with only differentiation and little of the other stuff, if only to check my own computations (in economics) as I have

[racket-users] Big thanks for the Racket Plot design

Hi all, since complaints about bugs are probably more common than compliments about smooth experiences, I just wanted to say thank you to whomever designed the interface for the Racket plot library (and DrRacket for making the saving of images so pain-free). I had to get some plots done
