I''ve been running into this problem with gems and plugins recently when using ruby 1.9.1p0. A review of syntax.y from ruby 1.8.7 and 1.9.1 shows the grammar rule for then no longer includes the literal symbol '':''. This change causes commonly used idioms for case expressions and loops to fail. These no longer work: case when CONDITION : BODY end while BOOLEAN : BODY end until BOOLEAN : BODY end for NAME in EXPRESSION : BODY end Am I mistaken? Is this a feature? This is the question I asked the Ruby language group (redmine.ruby- lang.org Bug #1389) which produced this response: It was an "accidental" feature in the first place. It''s been removed to simplify the new hash literal syntax. At this point, I''ve found problems with rubyist-aasm and attachment- fu. No extensive search here just trying the plugins/gems I''ve used. So, if you''re trying to work with ruby 1.9 and you''re seeing error messages that look like: attachment_fu.rb:106: syntax error, unexpected tIDENTIFIER, expecting keyword_then or '','' or '';'' or ''\n'' search out the '':'' and replace it with ''then'' --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
