1.10 + * Date: 23 October 2001
1.11 + *
1.12 + * SUMMARY: Testing regexps with the global flag set.
1.13 + * NOT every substring fitting the given pattern will be matched.
1.14 + * The parent string is CONSUMED as successive matches are found.
1.15 + *
1.16 + * From the ECMA-262 Final spec:
1.17 + *
1.18 + * 15.10.6.2 RegExp.prototype.exec(string)
1.19 + * Performs a regular expression match of string against the regular
1.20 + * expression and returns an Array object containing the results of
1.21 + * the match, or null if the string did not match.
1.22 + *
1.23 + * The string ToString(string) is searched for an occurrence of the
1.24 + * regular expression pattern as follows:
1.25 + *
1.26 + * 1. Let S be the value of ToString(string).
1.27 + * 2. Let length be the length of S.
1.28 + * 3. Let lastIndex be the value of the lastIndex property.
1.29 + * 4. Let i be the value of ToInteger(lastIndex).
1.30 + * 5. If the global property is false, let i = 0.
1.31 + * 6. If i < 0 or i > length then set lastIndex to 0 and return null.
1.32 + * 7. Call [[Match]], giving it the arguments S and i.
1.33 + * If [[Match]] returned failure, go to step 8;
1.34 + * otherwise let r be its State result and go to step 10.
1.35 + * 8. Let i = i+1.
1.36 + * 9. Go to step 6.
1.37 + * 10. Let e be r's endIndex value.
1.38 + * 11. If the global property is true, set lastIndex to e.
1.39 + *
1.40 + * etc.
1.41 + *
1.42 + *
1.43 + * So when the global flag is set, |lastIndex| is incremented every time
1.44 + * there is a match; not from i to i+1, but from i to "endIndex" e:
1.45 + *
1.46 + * e = (index of last input character matched so far by the pattern) + 1
1.47 + *
1.48 + * Thus in the example below, the first endIndex e occurs after the
1.49 + * first match 'a b'. The next match will begin AFTER this, and so
1.50 + * will NOT be 'b c', but rather 'c d'. Similarly, 'd e' won't be matched.
