Dir.glob hidden files

Help & Support
1

Hi everyone, recently I did a test and I saw the new way for Dir.glob don’t return the hidden files, even I tried to set all different options.

I did that test:

puts Dir.glob(Dir["**/*"], File::MatchOptions::DotFiles)

puts Dir.glob(Dir["**/*"], File::MatchOptions::NativeHidden)

puts Dir.glob(Dir["**/*"], File::MatchOptions::OSHidden)

I have the same result in all cases, even there is a hidden file called .fil:

Each of your Dir.glob calls operate on the return value of Dir["**/*"], a method which does not return hidden files by default. So what you’re doing is asking to find all files, including hidden ones, among a list of non-hidden files. By definition, that can’t return hidden files.

Try this instead:

Dir.glob(["**/*"], match: :dot_files)

Note that I removed the second Dir, so it’s just passing the pattern rather than the list of files. Also, since File::MatchOptions is an enum, you can pass a symbol to it — you don’t need a fully qualified name.
