I tyied but failed, here is my .gnus.el:
----------------------------------
(copy-face 'default 'face-3)
(set-face-foreground 'face-3 "DeepSkyBlue1")
(setq gnus-face-3 'face-3)
(defun gnus-user-format-function-c (header)
"Return a string like MM/DD from a Date header."
(condition-case ()
(format-time-string
"%m/%d"
(safe-date-to-time (mail-header-date header)))
(error " - ")))
(defun gnus-user-format-function-z (header)
"test dynamic color"
(if (string=
(format-time-string "%m%d")
(format-time-string
"%m%d"
(safe-date-to-time (mail-header-date header))))
;; then
(set-face-foreground 'face-3 "red")
;; else
(set-face-foreground 'face-3 "blue"))
"")
(setq gnus-summary-line-format "%uz%U%R%z %3{%uc%}: %1{%B%-23,23n%} %s
\n")
-------------------------------------------------------------
It seemed that emacs only display the summary buffer after the last
call of gnus-user-format-function-z.
So the color is all the same.
Is there any advice?
