Re: Need suggestions on how to write rand-interleave test.check generator.

Another kind of approach that would be worth trying is adapting test.check's own shuffle generator . It generates a sequence of pairs of indexes and t

Show: Naive data fitting with Nyarlathotep

Hey! Nyarlathotep is a tiny mathematical function generator that can be used as a (very naive) data fitting tool. It generates random functions and tests them against provided constraints. I don't think it's of any practical use, but it is fascinating to

Re: Need suggestions on how to write rand-interleave test.check generator.

Oh okay. So if a value given to gen/return function is coming via a generator will shrink because that generator will shrink. But say (gen/return [1 2 3 4]) will never shrink because it is saying just return it as it is and never shrink this. Got it! :) On Fri, Aug 14, 2015 at 10:34 PM, Carlo Zanc

Re: Need suggestions on how to write rand-interleave test.check generator.

What it means is that the value returned by gen/return can't be shrunk. Shrinking is done by constructing a (lazily evaluated) tree of "smaller" forms of the same thing. So a number, let's say 4, contains a tree of smaller numbers (0, 1, 2, and 3) which specify how to shrink it. (The tree is const

Re: Need suggestions on how to write rand-interleave test.check generator.

Ah right! I knew I had to use gen/choose for this, I am still grokking bind :) Thanks for your help! That indeed did the trick for me :) One thing I am clear about is, If I use gen/return it says it'll not shrink. Does that mean when a test fails for a certain order, it won't try to shrink that o

Re: Need suggestions on how to write rand-interleave test.check generator.

Hey Mayank! Similarly to your attempt last time, you need to use gen/bind to get the result of a generator which you can then use to make a new generator. (defn- rand-interleave* [coll acc] (if (seq coll) (gen/bind (gen/choose 0 (dec (count coll))) (fn [index]

Re: Clojure Truck Factor

Hi Guilherme, I am not a Clojure developer (I only use it), so maybe I'm speaking out of line. I would first like to thank you for the initiative; as an industry, I believe we direly need more quantitative, scientific studies of our practices, so I'm really happy to see this. There is of course a

Need suggestions on how to write rand-interleave test.check generator.

Hi Everyone, Here's the problem I am facing, I need to write a generator which takes any number of sequences, interleaves them but maintains the order within each sequence. Assume each sequence has at least one element. For example: (rand-interleave [1 2 3 4] [:a :b] [:A :B :C :D :E]) > => [:a 1

Re: Is this resource only loaded once?

Once you've AOT compiled that (which is necessary for the class to be actually generated), slurp won't be called again. Beware, however, that `def` (and hence `slurp`) will be executed by the compiler, at compile time, in the context (classpath, cwd, etc.) of the compiler, which may not be what you

When a java class uses the compiled Test (gen-class) from test namespace. Everytime the static function -run is called, will parser be slurped again or only once ? (ns test (:gen-class :name Test :methods [ ^:static [run [] String])) (def parser (slurp "..
