I've seen some confusing comments about Mac OS X "curses" versus "ncurses", but am left with the impression that it's still ncurses (in a different directory, etc, but still the same code). Even still, 5.4 is nearly three years old, and there's a year-old 5.5 release which Mac OS X should be using. > > Also note (as you already did) that there's a known workaround (use the > > terminal description that uses the single-character ^N and ^O rather than > > \E(B, etc. > > But this time, these characters break "less"! > > http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=399848 That's odd, since "less" has always been a termcap application. Perhaps it's a regression, e.g., changes by someone using a terminfo underneath. > And I don't know if this is related to changes in ncurses: > > http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403612 Since "less" uses only the termcap interface, it would only be related to changes in that one area. Essentially the changes to sgr0 were made necessary by a long-ago equating of terminfo "sgr0" and termcap "me". They're not identical: a) several years ago, I made changes to allow termcap applications to assume that "me" (sgr0) did not reset line-drawing since termcap applications generally did not support that feature. b) that change only worked for single-bytes - and the change I noted yesterday was a fix for that. The fix was needed to allow using multi-byte \E(B, etc., to support luit. c) further changes past that point were refinement (improving the interaction with applications that had not been fixed with (b)). -- Thomas E.
