I am trying to set the foreground color for first line in my buffer which has global-font-lock ON.

Buffer contents - 

(ignore) 
(add-text-properties 1 8
                                         '(:foreground "red"))
;;since add-text-properties didn't work, i tried with add-face-text-property
(add-face-text-property 1 8 '(:foreground "red"))

When i do eval-buffer, i like to see the first line, (ignore) made red. But it is not so. I referred here to know the function, add-text-properties doesn't work when font-lock mode is ON.

Is there a way one can change the properties for text that lies between a start and end point?

When font-lock-mode is in use, you can use the font-lock-face property instead of face.

(add-text-properties 1 8 '(font-lock-face (:foreground "red")))

  • what if you want the face to stay but also want to apply something like an underline?

    Interesting. You could set font-lock-face to the current value of face plus what you want to add. (defun add-to-font-locked-face (b e v) (put-text-property b e 'font-lock-face (cons v (get-text-property b 'face)))). Then (add-to-font-locked-face 1 11 '(:underline t)). Seems to work well if you add to a whole font locked word.
