I'd like to get the single components of a path as an array.
I came to these two solutions:
path = '/usr/share/doc/less/'
parts = path.split(File::Separator)
p parts # => ["", "usr", "share", "doc", "less"]
require 'pathname'
parts = []
Pathname.new(path).each_filename {|f| parts << f}
p parts # => ["usr", "share", "doc", "less"]
String.split()
Is this robust and portable?
Pathname.each_filename()
Looks a bit verbose for Ruby. However, this should be portable, right?
Are there better ways? Have I missed something that's standard Ruby?
That's spot on. Pathname
is part of ruby's standard library, and it should be an entirely portable solution.
You can just use this:
Pathname.new(path).each_filename.to_a
Or even:
Pathname(path).each_filename.to_a
