That's looks like an interesting article, thanks. It doesn't really matter if all those languages share implementation code. I just wanted to say that leftmost-longest is not what many popular languages do. Java doesn't offer a repl, so I can't be bothered to check that ;-) Tcl does do a longest match, Javascript does the same as Python, Ruby and Perl (at least the Spidermonkey implementation; the spec suggests that this is correct ( http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-262.pdf , 15.10.2.3)). nico$ tclsh % regexp {ab|abc} "abc" matched 1 % puts $matched abc nico$ ~/src/js/spidermonkey/src/Darwin_DBG.OBJ/js js> "abc".match(/ab|abc/) ab Nico --~--~---------~--~----~------------~-------~--~----~ You received this message from the "vim_dev" maillist.
