Subject: Stop recognizing :#{} as symbol in ruby-mode
X-Git-Tag: emacs-25.0.93~115
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=9b16bc2;p=emacs.git

Stop recognizing :#{} as symbol in ruby-mode

* lisp/progmodes/ruby-mode.el (ruby-font-lock-keywords): Remove
the weird part that recognized colon followed by interpolation
construct without quotes (e.g. ':#{abc}') as symbol, which is just a
syntax error in any modern version of Ruby.  Fix nearby bug reference.
