copied!<p>I don't see, what's wrong, but are you sure there was no type and you requested the file you expected?</p> <p>I would modify the code a bit:</p> <pre><code>class Hola::Translator def initialize(language, exceptions = false) @language = language @exceptions = exceptions end def hi case @language when :spanish "hola mundo" when :english "hello world" else raise ArgumentError, "Unsupported language #{@language.inspect}" if @exceptions "hello world" end end end </code></pre> <p>You support two languages: Spanish and English. Other languages are detected and you can select, if you get an error or an alternative (english) text.</p> <p>You can start it with:</p> <pre><code> class Hola def self.hi(language = :english) translator = Translator.new(language, true) ## <-- Modified translator.hi end end require 'hola/translator' </code></pre> <p>One advantage of the expection: You can see, which file really calls the exception.</p> <p>Some other remarks:</p> <ul> <li>I would recommend to define <code>Hola</code> as a module, not a class.</li> <li>Instead the <code>raise</code> you could define a logger and report an error.</li> </ul> <p>Example:</p> <pre><code>require 'log4r' module Hola LOG = Log4r::Logger.new('Hola') class Translator def initialize(language) @language = language end def hi case @language when :spanish "hola mundo" when :english "hello world" else LOG.error("Unsupported language #{@language.inspect}") "hello world" end end end def self.hi(language = :english) translator = Translator.new(language) translator.hi end end #module Hola p Hola.hi p Hola.hi(:english) p Hola.hi(:spanish) p Hola.hi(:german) puts "Activate Hola-warnings" Hola::LOG.outputters << Log4r::StdoutOutputter.new('stdout') p Hola.hi p Hola.hi(:english) p Hola.hi(:spanish) p Hola.hi(:german) </code></pre> <p>After activating the logger, you are informed, if you have a type in <code>:spanish</code> (that's the error I would expect).</p>
