If had a Ruby linter or Ruby checkstyle program, I would want to configure it to detect the following things:

• Duplicate methods in the same class, module (this produces a warning at runtime if warnings are enabled)
• Parens in methods with no arguments
• Missing parens in methods with arguments (or check that there aren't parens, if you're into that)
• Method indentation is consistent
• Consistent block spacing (.map{|ea| ea} vs. .map {|ea| ea} vs. .map { |ea| ea }, etc.)
• private, protected are consistently indented (or outdented)
• do...end blocks must be used beyond a certain line length
• No semi-colons (possible exceptions for one-line exception classes)

# How to read a file in Ruby
file_name = "example.txt"

# It's simple.
# Open the file in read mode ("r"), read it, and close it.
f = File.open(file_name, "r")
f.read
f.close

# Though "r" is the default mode, so you can remove that.
