From: Albert Schlef Date: 2011-02-21T23:29:34+09:00 Subject: Re-learning the library Hello. After a long time I haven't touched Ruby I want to come back. I want to refresh my memory about the various methods that come with the built-in classes; e.g., String, Array, Hash. So I do, for example, "ri String" and here's a problem: I get a long list of methods but some of them are defined by some gem or 3rd party library. That's a problem, because I want to see only the methods defined by Ruby itself. How do I do this? -- Posted via http://www.ruby-forum.com/.
