ok - now that I have the terminfo installed and testing it, I see what
you're talking about. Turning on ncurses' trace, this is what lynx is doing:
called {has_colors()
return }1
called {start_color()
+ called {tparm("\e[%p1%{30}%+%dm", 7)
+ return }"\e[37m"
+ called {tparm("\e[%p1%'('%+%dm", 0)
+ return }"\e[40m"
started color: COLORS = 8, COLOR_PAIRS = 64
return }0
called {use_default_colors()
+ called {assume_default_colors(-1,-1)
+ return }-1
return }-1
called {init_pair(1,3,-1)
return }-1
called {init_pair(2,1,-1)
return }-1
called {init_pair(3,7,-1)
return }-1
called {init_pair(4,5,-1)
return }-1
called {init_pair(5,6,-1)
return }-1
called {init_pair(6,7,2)
return }0
called {init_pair(7,4,-1)
return }-1
called {init_pair(8,3,4)
return }0
It's trying to use default-colors, but that terminfo doesn't support it.
And lynx isn't checking the result. The color pairs will end up being
0's (black/black).
Either way it's my bug, but it helps to know which (and since I'm trying
to work on lynx this week instead of ncurses, that's at least in the right
direction).
