re: Fix non-termination for a certain regular expression
The following code never terminates:
fail() ->
Str = "http:/www.flickr.com/slideShow/index.gne?group_id=&user_id=69845378@N0",
EMail_regex = "[a-z0-9!#$%&'*+/=?^_`{|}~-]+"
++ "(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*"
++ "@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+"
++ "(?:[a-zA-Z]{2}|com|org|net|gov|mil"
++ "|biz|info|mobi|name|aero|jobs|museum)",
io:format("about to run...~n"),
Ret = re:run(Str, EMail_regex),
io:format("Ret is ~p~n", [Ret]).
Fix it by having pcre_exec remember match_call_count between restarts.
