I’m looking at the documentation for FileUtils.
I’m confused by the following line:
FileUtils.cp %w(cgi.rb complex.rb date.rb), '/usr/lib/ruby/1.6'
What does the %w mean? Can you point me to the documentation?
%w(foo bar)is a shortcut for["foo", "bar"]. Meaning it’s a notation to write an array of strings separated by spaces instead of commas and without quotes around them. You can find a list of ways of writing literals in zenspider’s quickref.
