Re: [racket] Racket v5.3.2

Thanks Eli, Ran all my code under 5.3.2 - looking good. I'm definitely interested in looking into the math lib. BTW, ever since 5.3.1 (I think), the debugger acts a little different, in the variables pane it only shows the beginning of lists. How can I see the entire list? If I require planet

[racket] Racket v5.3.2

Racket version 5.3.2 is now available from http://racket-lang.org/ Core Libraries: * The new `math' library provides functions and data structures for working with numbers and collections of numbers. Functions include non-elementary (such as gamma, zeta, Lambert's W), number-theoretic (

Re: [racket] How to invoke a blocking foreign function without blocking whole racket?

Also cool! It's a good idea to parse errno.h into racket defines. It can be extracted to a standard library such as C define reader. The new package system https://plt-etc.byu.edu:9004/search can make package search. Cheers, Haiwei On 1 February 2013 11:01, Sam Phillips wrote: > On Wed, Jan 3

[racket] [Racket] Finding files

Can Racket be made to detect the PATH environment variable in Windows 7? If not, is there a way of emulating it so that one does not have to write out the complete path of any file mentioned in Racket code? This includes data files the program might be writing to or reading from. Also, I am loo
