Re: Is still idiomatic the ant simulation code?
Hi Gary, Your examination makes perfect sense in the context. Thanks for your help!

Re: Is still idiomatic the ant simulation code?
Hi Yu, This is a pretty dense (and IMHO non-idiomatic) piece of Clojure code. Without reading the paste you provided, I can at least tell you what appears to be happening here, given Clojure's evaluation semantics: 1. The [move ...] expression creates a vector of three functions. 2. The [(if ...)] expression creates a vector of three values (presumably numeric) resulting from calls to the ranks function. 3. The (wrand ...) form calls wrand on the ranks vector to presumably produce an integer index into the [move ...] vector. 4. The [move ...] vector is called on wrand's result, which should return one of the three functions it contains. 5. The function returned from step 4 is called on loc.

Re: Is still idiomatic the ant simulation code?
What's the meaning of the following code: (([move #(turn % -1) #(turn % 1)] (wrand [(if (:ant @ahead) 0 (ranks ahead)) (ranks ahead-left) (ranks ahead-right)])) loc))) in https://www.refheap.com/paste/3099 from line 192 to 195? Sorry to bother you, it's new to me, and it's really hard to Google, as the characteristic of the code is not well defined. I'm learning Clojure in ad-hoc manner, so I might not be aware some Clojure expression. Giving me some pointer to study further would be sufficient. By the context, it seems that it's trying to take a move. Thanks a lot!

That's great. I've also noticed the sample still uses defstruct which is made obsolete by defrecord.

The ants demo is definitely dated. It's not terrible, but the code could use some polishing/simplifying using newer additions to the language. -S -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Is still idiomatic the ant simulation code?
I'm preparing an informal presentation about clojure concurrency and my plan is use the ant colony demo. Given the amount of changes in clojure since the time that code was written I wonder if the code is still idiomatic or parts of it should be adapted to modern clojure. Any ideas would be much appreciated. Thanks, Juan Manuel -- You received this message because you are subscribed to the Google Groups "Clojure" group.
