The ECMA3 section is: + * + * 15.10.4.1 new RegExp(pattern, flags) + * + * If pattern is an object R whose [[Class]] property is "RegExp" and + * flags is undefined, then let P be the pattern used to construct R + * and let F be the flags used to construct R. If pattern is an object R + * whose [[Class]] property is "RegExp" and flags is not undefined, + * then throw a TypeError exception. Otherwise, let P be the empty string + * if pattern is undefined and ToString(pattern) otherwise, and let F be + * the empty string if flags is undefined and ToString(flags) otherwise. + * + * + *The current test will check the first scenario outlined above: + * + * "pattern" is itself a RegExp object R + * "flags" is undefined + * + * We check that a new RegExp object obj2 defined from these parameters + * is morally the same as the original RegExp object obj1. Of course, they + * can't be equal as objects - so we check their enumerable properties... + * + * In this test, the initial RegExp object obj1 will include a + * flag. This test is identical to test 15.10.4.1-3.js, except that + * here we use this syntax: + * + * obj2 = new RegExp(obj1, undefined); + * + * instead of: + * + * obj2 = new RegExp(obj1); + */ +//----------------------------------------------------------------------------- +var BUGNUMBER = '61266'; +var summary = 'Passing a RegExp object to a RegExp() constructor'; +var statprefix = 'Applying RegExp() twice to pattern '; +var statmiddle = ' and flag '; +var statsuffix = '; testing property '; +var singlequote = "'"; +var i = -1; var j = -1; var s = ''; +var obj1 = {}; var obj2 = {}; +var status = ''; var actual = ''; var expect = ''; var msg = ''; +var patterns = new Array(); +var flags = new Array(); + + +// various regular expressions to try - +patterns[0] = ''; +patterns[1] = 'abc'; +patterns[2] = '(.*)(3-1)\s\w'; +patterns[3] = '(.*)(...)\\s\\w'; +patterns[4] = '[^A-Za-z0-9_]'; +patterns[5] = '[^\f\n\r\t\v](123.5)([4 - 8]$)'; + +// various flags to try - +flags[0] = 'i'; +flags[1] = 'g'; +flags[2] = 'm'; +flags[3] = undefined; + + + +//------------------------------------------------------------------------------------------------- +test(); +//------------------------------------------------------------------------------------------------- + + +function test() +{ + enterFunc ('test'); + printBugNumber(BUGNUMBER); + printStatus (summary); + + for (i in patterns) + { + s = patterns[i]; + + for (j in flags) + { + f = flags[j]; + status = getStatus(s, f); + obj1 = new RegExp(s, f); + obj2 = new RegExp(obj1, undefined); // see introduction to bug + + reportCompare (obj1 + '', obj2 + '', status); + } + } + + exitFunc ('test'); +} + + +function getStatus(regexp, flag) +{ + return (statprefix + quote(regexp) + statmiddle + flag + statsuffix); +} + + +function quote(text) +{ + return (singlequote + text + singlequote); +} |
