Regex matching of URLs is difficult: https://mathiasbynens.be/demo/url-regex It doesn’t seem that src/markdown.c uses regexes. At least, I don’t see any “regex” or “regcomp” text in that file. A simpler method that may also work is: 1. Count parens and don’t close the URL until the paren count goes to 0. (Open paren = +1, closed = -1.) 2. …unless you hit a whitespace, EOL, or other thing after a closed paren that clearly means the URL is finished. That would let you have unbalanced parens, too. _______________________________________________ fossil-users mailing list fossil-users@lists.fossil-scm.org http://lists.fossil-scm.org:8080/cgi-bin/mailman/listinfo/fossil-users
