FFAP and Ruby in Emacs
If you want to use FFAP (find-file-at-point) in ruby-mode you can add this to your .emacs (defvar ruby-program-name "ruby") (defun ruby-module-path(module) (shell-command-to-string (concat ruby-program-name " -e " "\"ret='()';$LOAD_PATH.each{|p| " "x=p+'/'+ARGV[0].gsub('.rb', '')+'.rb';" "ret=File.expand_path(x)" "if(File.exist?(x))};printf ret\" " module))) (eval-after-load "ffap" '(push '(ruby-mode . ruby-module-path) ffap-alist)) When you do ffap (i bind it to C-x f) near a require ‘PP’ for example it will find it in your ruby path.
