Ciao Mohammad In my own testing so far this more minimal regex seems to work ... !!
- pattern="^\ *(https?|ftp|file|news|data|mailto):.+$ With something like this ... - {{{ [<url>trim[https://]trim[http://]trim[www.]trim[ftp://]trim[file:///]trim[news:]trim[mailto:]split[/]!is[blank]first[]join[.]] }}} Any of those protocols a user does not support yet in a browser should be prompted for by the BROWSER. Just a comment. NOT fully tested yet but seems okay so far. TT -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
