|
|
|
+ * Accepts a string to search, a left and right format delimiter
|
|
|
+ * as regex patterns, and optional regex flags. Returns an array
|
|
|
+ * of matches, allowing nested instances of left/right delimiters.
|
|
|
+ * Use the "g" flag to return all matches, otherwise only the
|
|
|
+ * first is returned. Be careful to ensure that the left and
|
|
|
+ * right format delimiters produce mutually exclusive matches.
|
|
|
+ * Backreferences are not supported within the right delimiter
|
|
|
+ * due to how it is internally combined with the left delimiter.
|
|
|
+ * When matching strings whose format delimiters are unbalanced
|
|
|
+ * to the left or right, the output is intentionally as a
|
|
|
+ * conventional regex library with recursion support would
|
|
|
+ * produce, e.g. "<<x>" and "<x>>" both produce ["x"] when using
|
|
|
+ * "<" and ">" as the delimiters (both strings contain a single,
|
|
|
+ * balanced instance of "<x>").
|
|
|
+ *
|
|
|
+ * examples:
|
|
|
+ * matchRecursiveRegExp("test", "\\(", "\\)")
|
|
|
+ * returns: []
|
|
|
+ * matchRecursiveRegExp("<t<<e>><s>>t<>", "<", ">", "g")
