Hello. I would report a bug of regexp. * Problem
"aba" =~# '^\(.\+\).*\1$' This expression is equivalent to 1 when 'regexpengine' is set to 1. However, when it is set to 0 or 2, the expression is equivalent to 0. Backward reference seems to fail. Note that below expression gets 1 whatever the value of 'regexpengine' is. "aa" =~# '^\(.\+\).*\1$' * Environment - Vim 7.4-45 - Ubuntu 12.04 Regards, Hayashida Ryuichi -- -- You received this message from the "vim_dev" maillist. Do not top-post!
