STINNER Victor <vstin...@redhat.com> added the comment:
On my Fedora 30 with libncursesw, A_COLOR = 0xff00.
After my change, _curses uses:
static inline short
attr_to_color_pair(int attr)
{
return (short)((attr & A_COLOR) >> 8);
}
...
setcchar(&wcval, wstr, attr, attr_to_color_pair(attr), NULL);
...
If someone gets troubles with attr passed "directly" as the 3rd argument of
setcchar(), we can try to pass (attr & ~A_COLOR) instead. On my Linux, it would
mean: only pass the low 8 bits of attr.
But since it "just" works on my Linux, I prefer to only make minimum changes to
fix this issue on Linux.
