A-Star Search Implementation

Hi, To teach myself Clojure and A-Star search, I mocked up a quick demo program. I don't know if anyone else would be interested in seeing it, but it demos a few things, including calling Clojure from Java, building / running from a Maven environment, and of course A-Star. I'd appreciate any cri

se you need to teach core.match how to use DateTimes <https://github.com/clojure/core.match/wiki/Pattern-Matching-Java-Objects>. I hope that helps! Josh P.S. In future questions you pose, you should probably state the version of Clojure you’re using, as well as the versions of any libraries

Re: structuring parallel code

If your goal is “to operate on large data structures in parallel” then you’ll probably find Clojure’s reducers library to be helpful. On Monday, January 30, 2017 at 9:38:01 PM UTC-5, Brian Craft wrote: > > ans: this scales badly. > > There must be a way i

"Soft" failures with spec?

e times. 2. Use a single spec, but have rules for what ::s/problems are acceptable. So, what do you think? Has anyone tried anything along these lines? Does this sound fundamentally wrongheaded, trying to make spec do something it’s ill-suited for? Cheers, Josh Tilles 79 Madison Ave, 4th Floo

Re: with-open pattern

I think the “reducible streams” approach described by Paul Stadig here has potential. It might not cover all of the scenarios you’re thinking of, though. On Thursday, May 4, 2017 at 1:35:48 PM UTC-4, Brian Craft wrote: > > The with-open st

Re: Can't stop the system component

e stop implementations are returning nil. (The value of a (println ,,,) expression is nil.) I hope that helps, Josh P.S. You should be able to just use component/start; you shouldn’t need to use component/start-system explicitly. On Tuesday, June 6, 2017 at 10:42:22 AM UTC-4, D.Bushenko wrote: >

I think Stu Halloway’s proof-of-concept is at least close to what you want: https://gist.github.com/stuarthalloway/f4c4297d344651c99827769e1c3d34e9. (Here’s the context for that code, in case you were curious.) btw, you might want t
