How to accept only ordered collections in spec


How to accept only ordered collections in spec

I hope this helps . Specs for sequences (regex specs) should not match ordered, that is sequential collections. This was a bug that has been fixed in current versions of spec, see CLJ-2183.
In Clojure 1.10.0-RC5 the results are as expected:
code :
(s/conform ::path [1 2 3])   ; => [1 2 3]
(s/conform ::path #{1 2 3})  ; => :clojure.spec.alpha/invalid

(s/explain ::path #{1 2 3})
;; #{1 3 2} - failed: (or (nil? %) (sequential? %)) spec: :user/path

it should still fix some issue It's more about the complexity of the data structure. If you have a list of primitive things such as strings, use an array ( whether it's ordered or not ). If you have more complex data structure which requires key/value pairs, use an object literal.
If you are storing metadata, for example:
code :
var things = [
    {"name":"computer","price":300},
    {"name":"mouse","price":20},
];
var person = {
     age: 23,
     walk: function(){},
     name: "john"
};

wish help you to fix your issue The browser is responsible for accepting and processing the response. It wouldn't make much sense to manipulate your XHR to say it accepts gzip, for example, when you couldn't do anything with it. Can you just set a custom header value?

hope this fix your issue I'm using Cucumber with Capybara in Rails 4.2, but I'm not using RSpec. I've been sticking with Minitest. I've been using minitest:spec in most of my tests. , Put this code into features/support/env.rb
code :
Before do
  Thread.current[:current_spec] = self
end

it fixes the issue I wish to represent a sequence of collections of strings. The inner collections should all have same length. , I would state the spec as something like
code :
(s/def ::stuff 
  (s/and 
    (s/every (s/coll-of string?)) 
    #(or (empty? %) 
         (apply = (map count %)))))

it should still fix some issue , Create the regex pattern independently from the spec:
code :
(require '[clojure.spec :as s] '[clojure.spec.gen :as gen])

(def pattern 
  (s/cat :sym symbol? :str string? :kws (s/* keyword?)))

(s/def ::solution
  (s/with-gen (s/and vector? pattern) 
              #(gen/fmap vec (spec/gen pattern))))

(s/valid? ::solution '(af "5" :key))  ;; false

(s/valid? ::solution ['af "5" :key])  ;; true

(gen/sample (s/gen ::solution) 4)
;; ([m ""] [. "" :Q] [- "" :?-/-9y :_7*/!] [O._7l/.?*+ "z" :**Q.tw.!_/+!gN :wGR/K :n/L])
