In vim this catches opening parenthesis at the start of the line followed by a digit followed by an opening figure brace, 1, comma, 3, closing figure brace, any character, closing parenthesis, 3, any character, opening parenthesis, digit, opening figure brace, 1, comma, 3, closing figure brace, closing parenthesis. Obviously you do not have such lines in a file. Note that it is not a regex for IPv4 address in any regex engine I know about: e.g. (...)3 is capturing group followed by 3 in PCRE, dot represents any character, not only the dot itself, in all of PCRE, BRE, ERE, vim. Check out :h regex for the correct syntax. > What's wrong? > > Thanks for any tips. > > Best, > steve > > > -- > -- > You received this message from the "vim_use" maillist. > Do not top-post!
