Hi all.
I've encountered enigmatic error message while learning rdoc. This is
the simple program which tests RDoc:
#!/usr/local/bin/ruby -w
# == Synopsis
# Test synopsis
require "optparse"
require "rdoc/usage"
opts = OptionParser.new
opts.on("-h", "--help") { RDoc::usage }
opts.parse(ARGV) rescue RDoc::usage('usage')
puts "hello"
When I run above program like './test.rb', ruby says
"/usr/local/lib/ruby/1.8/rdoc/ri/ri_formatter.rb:46: warning: (...)
interpreted as grouped expression"
Why is this warning raised? I have no idea what grouped expression is.
Sincerely,
Minkoo Seo
