string res = gmatch(string re, string target, string res) |
Description: |
Draft - this is a very simple routine that took very little time or effort (or thought) to write, and may
change in later releases.
Applies the regular expression re (in string or pre-compiled format) to target and returns res with any substitutions for \1 to \9, or -1 if no match could be found. re: a regular expression such as "a(b*)" or the result of applying regex_compile() to such a string. target: a string to be matched against the regular expression. res: a string containing \1 to \9 that should be replaced with the results of any match. Returns: an updated res or -1 if no match could be found. |
Example: |
?gmatch(`(\w+) changed to (\w+)`,"red changed to green",`\2 <- \1`) -- yields "green <- red" |
