In the process of porting an old DOS game to linux using fpc, I'm having some trouble getting the textcolor(0)/textbackground(0) and textcolor(8)/textbackground(0) color combinations to display properly using ocrt and ncrt. textcolor(0)/textbackground(0) displays as white text on a black background (the same as
textcolor(7)/textbackground(0)), and textcolor(8)/textcolor(0) displays as bright white text on a black background. (the same as textcolor(15)/textbackground(0))

Interestingly enough, these combinations work as expected when using the regular crt module.

I suspect this might be happenning because these color combinations are being mapped to ncurses color pair 0 (with and without the bold attribute), and in ncurses color pair 0 can't be modified via the init_pair function. Ncurses provides an additional function, assume_default_colors, which can be used to modify color pair 0. However, it seems that no wrapper for this function is provided in the fpc ncurses package. Is there a good reason for this? Any suggestions for a workaround to this problem?

Thanks.

I submitted a patch to the ncrt/ocrt guy a bit ago... my *crt unit is now heavily modifed and does not work as documented or I would send you it...

In ncrt.inc:

After the lines

   { load the color pairs array with color pair indices (0..63 }
   For bg := 0 to 7 Do For fg := 0 to 7 do cp[bg,fg] := (bg*8)+fg;

Add:

   { Set color 0 to black on black (Also used for dark grey }
   cp[COLOR_BLACK,COLOR_BLACK]:=7;
   cp[COLOR_BLACK,COLOR_WHITE]:=0;

I think that was all that was required for the colour fixes.
