Suppose I have a
python-mode user buffer with content
import os, I can use
(buffer-substring (point-min) (point-max)) to get a colorized string
#("import os" 0 6 (fontified t face font-lock-keyword-face) 6 9 (fontified t))
But now I want to generate this using emacs lisp code like
(setq string (with-temp-buffer (python-mode) (font-lock-mode 1) (insert "import os") (buffer-substring (point-min) (point-max))))
but got result
#("import os" 0 9 (fontified nil))
So my question is how can I generate the same string just as I substring it from a truly existed user buffer?
Thanks in advance.
