| 9 * SUMMARY: Testing regexps with the global flag set. | |
| 10 * NOT every substring fitting the given pattern will be matched. | |
| 11 * The parent string is CONSUMED as successive matches are found. | |
| 12 * | |
| 13 * From the ECMA-262 Final spec: | |
| 14 * | |
| 15 * 15.10.6.2 RegExp.prototype.exec(string) | |
| 16 * Performs a regular expression match of string against the regular | |
| 17 * expression and returns an Array object containing the results of | |
| 18 * the match, or null if the string did not match. | |
| 19 * | |
| 20 * The string ToString(string) is searched for an occurrence of the | |
| 21 * regular expression pattern as follows: | |
| 22 * | |
| 23 * 1. Let S be the value of ToString(string). | |
| 24 * 2. Let length be the length of S. | |
| 25 * 3. Let lastIndex be the value of the lastIndex property. | |
| 26 * 4. Let i be the value of ToInteger(lastIndex). | |
| 27 * 5. If the global property is false, let i = 0. | |
| 28 * 6. If i < 0 or i > length then set lastIndex to 0 and return null. | |
| 29 * 7. Call [[Match]], giving it the arguments S and i. | |
| 30 * If [[Match]] returned failure, go to step 8; | |
| 31 * otherwise let r be its State result and go to step 10. | |
| 32 * 8. Let i = i+1. | |
| 33 * 9. Go to step 6. | |
| 34 * 10. Let e be r's endIndex value. | |
| 35 * 11. If the global property is true, set lastIndex to e. | |
| 36 * | |
| 37 * etc. | |
| 38 * | |
| 39 * | |
| 40 * So when the global flag is set, |lastIndex| is incremented every time | |
| 41 * there is a match; not from i to i+1, but from i to "endIndex" e: | |
| 42 * | |
| 43 * e = (index of last input character matched so far by the pattern) + 1 | |
| 44 * | |
| 45 * Thus in the example below, the first endIndex e occurs after the | |
| 46 * first match 'a b'. The next match will begin AFTER this, and so | |
| 47 * will NOT be 'b c', but rather 'c d'. Similarly, 'd e' won't be matched. | |
