font-lock-reference-face has been removed from Emacs

[ericsfraga]

This face had been marked as obsolete for some time, I guess, and it has now been removed from the development version of Emacs. Solution is to use a different font lock face, I guess, but I have no idea which one would be most relevant.

Thanks for the heads up!

Would not mind a PR.

You're welcome and, okay, I'll see if I can do something this week.

Found some time today. I am not au fait with pull requests etc. so I'll suggest the change required here. There is only one line affected, line 559 of graphviz-dot-mode.el. I would suggest changing that line to . font-lock-constant-face) I was going to suggest using font-lock-keyword-face but you are already using that.

Seem a good substitution.

Thanks for spotting this @ericsfraga! This was causing org-babel fontification errors in case of source blocks with options in them, such as this one:

#+begin_src dot
digraph {
  rankdir=LR
  a->b
}
#+end_src

I made a PR with your suggested fix.

@ppareit Hartelijk bedankt voor deze prachtige Emacs modus! :) 🙏 💯

[ppareit]

Perfect. I'm pulling this right now. Thanks to both!

[ericsfraga]

Excellent. Thank you!
