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. :slight_smile:
