Re: (doseq/lazy/interop)? problem, different behaviour when adding a println

Having not gone through your code in detail, I would suggest replacing `map` -> `mapv` to make it an eager operation so that state updates (i.e. ` next-states`) occur right away. The presence of laziness where it is not needed or expected (especially in Java interop code) can cause problems with t

Re: (doseq/lazy/interop)? problem, different behaviour when adding a println

stuff like `java.util.HashMap` with Clojure versions whenever possible. Again, the goal is to avoid clashes in the hidden assumptions of the two models. Alan On Mon, Apr 24, 2017 at 1:05 PM, Alan Thompson wrote: > Having not gone through your code in detail, I would suggest replacing > `

[ANN] Tupelo - Clojure With A Spoonful of Honey

​​ Version 0.9.39 of the Tupelo library has been released. Tupelo is a library of helper and convenience functions to make working with Clojure simpler, easier, and more bulletproof. I've been working on some parsing & validation code recently and had occasio

Re: Incomplete With Destructuring Lists

Don't try to force the destructuring DSL to do more than it was intended to do. Just do it manually (or write a macro if you really insist): (defn foo [& args] (let [ [a b c] (take 3 args) mid3 (take 3 (drop 3 args)) [g h i] (drop 6 args) ] (when (< 9 (count args))

How to Create Clojure `defn` Functions automatically?

A recent question on StackOverflow raised the question of the best way to automatically generate functions. Suppose you want to automate the creation of code like this: (def foo {:able"Adelicious!" :baker "Barbrallicious!" :charlie "Charlizable"}) (def bar {:able"Apple" :b

Re: How to Create Clojure `defn` Functions automatically?

Since the original question was in CLJS, which has neither `intern` nor `eval`, does that mean the macro mapping another macro approach is the only solution there? On Thu, May 11, 2017 at 9:18 AM, Alan Thompson wrote: > I like the idea of using `eval` and `memoize`. I'll have to keep

Re: def with function call - how often executed?

When clojure reads this, it immediately evaluates `(+ 1 2)` => 3 so your code looks like: (def x 3) So subsequent references to `x` just get the pre-computed value of 3 and don't know how it was derived. Alan On Thu, May 11, 2017 at 9:58 AM, Kevin Kleinfelter < kleinfelter.gro...@gmail.com>

Re: Functional Pattern to Replace Temp Var

You are already doing exactly the right thing by having a temporary variable. To be precise a code fragment like: (let [expensive-answer (some-fn x y z) final-result { :k1 (f1 expensive-answer) :k2 (f2 expensive-answer) :k3 (f3 expensive-answer) }
