I made some tests and it is not possible to use frame-parameter in the
ps-default-fg and ps-default-bg initialization, because, during Emacs
initilization, ps-print is loaded before the frame parameters are set.
1. Why is ps-print loaded before the frame parameters are set?
In what case is that so?
Well, I don't know why, but when the initialization code for
ps-default-bg and ps-default-fg include frame-parameter, the result is
always:
ps-default-bg "#ffffff" (white)
ps-default-fg "#222222" (gray98)
It doesn't matter if the background-color frame parameter is set to
"white", "DarkSlateGray", "black" or any other color in the
initial-frame-alist variable, the initialization value is always as above.
2. It would be possible to avoid computing the defaults for
ps-default-fg and ps-default-bg until a command is given to print
something. Would that solve the problem?
Well, it could solve the problem.
If the variables have a value (let's say, 'frame-parameter), the value
of them is calculated when any ps-print command is activated. And it's
used frame-parameter function to get the color value.
Could I implement this now in Emacs 22 or wait until after release?
