  <<SOMETHING
  

  does not trigger Heredoc syntax, but
  

  <<-SOMETHING
  

  does.

  Whats invalid about this issue?

  <<HEREDOC should be treated the same as <<-HEREDOC and is not.

  It is not treated the same because Textmate doesn't treat it the same. This is not a bug in Redcar or how Redcar uses the Textmate bundle for highlighting, and I would argue it is not a bug at all. Use "<<-HEREDOC" if you want syntax highlighting, "<<HEREDOC" if you don't, that is the intended behaviour.

  Not really. When you type <<HEREDOC, the content still gets highligted in some way.

  << gets higlighted as << operator that is used to add strings like message << " worl" HEREDOC gets higlighted as a CONSTANT

  If you think about this, this is clearly a bug, because <<HEREDOC is beginning of the Heredoc, not an operator followed by a constant.

  Textmate obviously has a bug there and so does Redcar.

  Tim's right this is Textmate behaviour, but not for the reason given. I believe this is because given this code:

  foo <<PI
  

  it's impossible to tell whether PI is the start of a heredoc or a constant value.

  At least without fully parsing the Ruby file, which is outside the scope of the syntax highlighter in it's current form.

  Maybe there is a way using the current parser.

  How does <<-HEREDOC work? It could have been intepreted as a << minus constant.

  Maybe we could make a rule that says <<A||<<B||<

  I'll look into it and report back.

  Maybe we could make a rule that says <<A||<<B||<<C ... <<||Z results in heredoc or that << operator needs to be <<[ a-z...].

  I'll look into it and report back.

  Ruby itself interprets both of these as a constant:

  foo <<-FOO
  

  &

  foo <<FOO
  

  So I'm now confused as to how the original code even worked...
