Forum: Ruby ruby -r debug -> "Emacs support available"

Forgive my ignorance, but what does that "Emacs support available" 
message mean? I can't find anything about it anywhere (possibly because 
the search terms are so common). What kind of support?

Emacs is a code editor[1] that can also run from the commandline. See
here: http://www.gnu.org/software/emacs/

I guess the "debug" library allows you to jump directly into the code
with emacs.

Although I’m a happy Emacs user, I’d be curious if "debug" really only
supports Emacs as an editor; I can’t imagine it doesn’t support the
other big console editor, VIM.

[1] Actually, Emacs is much more than an editor. But this is unrelated
here.

Did you look at debug.rb itself? It is one of the joys of ruby. Check 
it:

      if ENV['EMACS']
        stdout.printf "\032\032%s:%d:\n", binding_file, binding_line
      else
        stdout.printf "%s:%d:%s", binding_file, binding_line,
          line_at(binding_file, binding_line)
      end

Very wise words!  Thank you—I feel enriched now. :)
