Where can I find the version of ruby in which a particular function was added?

Question

Like the title, File.symlink to be exact.

I've looked in ruby-doc.org but haven't found anything. Any help?

Answer 1

If you look at APIdock you'll notice that they have this information at the top left, under the method name (versions that don't support the method can't be clicked). Examples:

• http://apidock.com/ruby/Enumerable/each_with_object
• http://apidock.com/ruby/File/symlink/class

Same for Rails versions btw.
