PHP PHPixme ternary Examples

Example #1

File: ternaryTest.php Project: rkgladson/PHPixme

 public function test_return()
 {
     $countArgs = function () {
         return func_num_args();
     };
     $this->assertInstanceOf(Closure, P\ternary($countArgs), 'ternary should return a closure');
     $this->assertEquals(3, P\ternary($countArgs)->__invoke(1, 2, 3, 4), 'ternary should eat all but three arguments');
 }

Example #2

File: S_tarlingTest.php Project: rkgladson/PHPixme

 public function test_scenario_tupleMaker($array = [1, 2, 3, 4])
 {
     // Test to see if we can fix array_map through starling to get the key with the value
     $kvTupple = function ($v, $k) {
         return [$k, $v];
     };
     $kvMap = P\curry(3, P\ternary('array_map'))->__invoke($kvTupple);
     $this->assertEquals(array_map($kvTupple, $array, array_keys($array)), P\S($kvMap, 'array_keys')->__invoke($array));
 }
