Then it would be better to rename it in all C files to not create Lisp symbols in C for both of them. > Second, I think doing this unconditionally might not be a good idea: > wouldn't it clash with what x_set_frame_parameters and > IT_set_frame_parameters do for their respective displays? It is called conditionally on non-window and non-dos systems so it doesn't clash with x_set_frame_parameters or IT_set_frame_parameters. > Third, please be sure to test this change with various ways one can > use to set colors on a tty, including these few: > > . emacs -fg FOO > . emacs -fg FOO -bg BAR > . emacs -bg BAR > . repeat the above 3 with -rv, and convince yourself that the above > 4 tests produce expected results I see there is a bug not caused by my patch: emacs -q -nw -rv sets the background mode to light on xterm. But since -rv switches foreground and background, it should switch the background mode too from light to dark on xterm. > . modify the default color with set-background-color and verify that > it is in effect for new frames created with "C-x 5 b" and the like For frames with undefined backgrounds it reuses the background mode specified with set-background-color.

On X this is handled in `if (EQ (param, Qbackground_color))' condition in update_face_from_frame_parameter(xfaces.c) which is reached from Fmodify_frame_parameters thru the following function calls: update_face_from_frame_parameter at xfaces.c:4490 x_set_background_color at xfns.c:911 x_set_frame_parameters at frame.c:2738 Fmodify_frame_parameters at frame.c:2280 Finternal_set_lisp_face_attribute at xfaces.c:4434 But on tty it doesn't go past the function Fmodify_frame_parameters due to the condition `if (FRAME_WINDOW_P (f))'. The explicit call to `Qframe_update_face_colors' I added in Fmodify_frame_parameters is on the else-branch of this condition. -- Juri Linkov http://www.jurta.org/emacs/ _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
