How to use

Include it as dependency

Inject in Controller

angular.module('kino', ['ngRules'])
        .controller('MyController', function($scope, $rules){
            $scope.num = 123;
            
            var rules = {
              "num": "number | maxLen: 5"
            };
            
            var r = $rules($scope, rules);

            $scope.r = r;
        });

Rules

    rules = {
            '*': 'required',
            p1: 'number| maxLen: 5',
            p2: 'email',
            p3: 'eq: p1',
            p4: '!eq: p2',
            p5: 'eq: \'can\'',
            p6: 'gt:p1',
            'date:not(:first-child)': 'gt:@group[index-1].date',
            'px:first-child': 'number',
            'py:not(:first-child)': 'maxLen: 5'
        };

Use custom rule

    r = $rules($scope, rules);       
    r.$setRule('customRule', (value) => {
        return /^\d[a-z]+\d$/.test(value);
    });

Validate

    //you can use r.$invalid to check the validation
    expect(r.$invalidate).toBe(true);
    
    //or check the field's validate like this
    expect(r.p1.$invalid).toBe(true);
