Ruby list directory with Dir['*'] including dotfiles but not . and

Question

How do I get Dir[\'*\'] to include dotfiles, e.g., .gitignore, but not . and ..?

I.e., is there a better way to do:

Answer 1

You can't with Dir[], but you can with Dir.glob, which Dir[] calls:

Dir.glob("*", File::FNM_DOTMATCH)

You can get rid of the . & .. easily:

Dir.glob("*", File::FNM_DOTMATCH).tap { |a| a.shift(2) }

But I think it’s probably best to stick with your original way:

Dir.glob("*", File::FNM_DOTMATCH) - %w[. ..]

(among other ways)

However, if you don’t require a more sophisticated glob than *, Dir#children may be all you need (can always further filter/grep the results if more filtering is needed):

Dir.children('.')
