    Do you want all keywords to be fontified differently, or only a subset?

  • My best guess is that you simply want to M-x customize-face RET font-lock-keyword-face and change the colour of that pre-existing face to something you prefer.

If you change "package" to "^package.*" I think it will match every line that starts with package to the end of the line. I don't know enough about go to know if that is always the right thing to do here.

  • I don't get what you want. You just want the package word in another color than it already is?

If I understand correct, just add the other keywords to the list. Something like:

(font-lock-add-keywords 'go-mode
;; change to desired operator regex
'(("package"  0 'my-font-lock-gokeyword-face)
  ("go"  0 'my-font-lock-gokeyword-face)
  ("defer"  0 'my-font-lock-gokeyword-face)
  ("package"  0 'my-font-lock-gokeyword-face)))

I understood you want the same color for all four keywords, then this is fine. Otherwise you can change the faces to whatever color you want for the keywords.
