Ruby Programming Language :: How add "Not-match" logic into Enumerable.grep?


	How add "Not-match" logic into Enumerable.grep? Say, I want to get all files in one folder. Since Dir.entries will have "." and ".." included. I want to strip them out with "grep". I tried to write in such a way as I can did similarly in Perl: log_files = Dir.entries(log_dir).grep(!/^\.\.?/) But, it is a syntax error to have "!/regex/" as grep's argument. Should I use some trick to make grep accept "not-match" regex? Hi, At Tue, 5 Jun 2007 18:55:02 +0900, Morgan Cheng wrote in [ruby-talk:254395]: > Say, I want to get all files in one folder.

Use #reject: Dir.entries(".").reject {\|x\| /\A\.+\z/ =~ x} robert
