Mutually exclusive options with Thor

Question

Is there any way to have two mutually exclusive options with Thor? For example, I need to provide an option of a list of something. I might have an option -l ent1 ent2 ent3 ent67, and I might have an option -f which I pass a file with contents ent1 ent2 ent3 ent67. Can these two options be made mutually exclusive with Thor without writing extra processing code in the method?

I haven't found a built-in way to do this, but you could accomplish it with your own simple check. Here's an example Thor command that does what you want.

desc "command", "A command that does something."
option :list, aliases: 'l', type: :array
option :file, aliases: 'f'
def list
  if options[:list] && options[:file]
    puts "Use only one, --list(-l) or --file(-f)"
    exit(0)
  end
  # Place the functions of the command here
end

Hope this helps!
