Ah, ha.

I went off on my own rant about it on the groff list. https://lists.gnu.org/archive/html/groff/2023-08/msg00106.html If OSC 8 fails--even if hyperlinks in terminal windows are discarded as a pointless fad--I will still be glad I added the `MR` macro to groff for the three other reasons I did so. (groff) NEWS: Inclusion of the `MR` macro was prompted by its introduction to Plan 9 from User Space's troff in August 2020. Its purpose is to ameliorate several long-standing problems with man page cross references: (1) the package's lack of inherent hyperlink support for them; (2) false-positive identification of strings resembling man page cross references (as can happen with "exit(1)", "while(1)", "sleep(5)", "time(0)" and others) by terminal emulators and other programs; (3) the unwanted intrusion of hyphens into man page topics, which frustrates copy-and-paste operations (this problem has always been avoidable through use of the \% escape sequence, but cross references are frequent in man pages and some page authors are inexpert *roff users); and (4) deep divisions in man page maintenance communities over which typeface should be used to set the man page topic (italics, roman, or bold). > > In the meantime it would be helpful if you could add a terminfo > > capability so that applications using terminfo but not curses per se > > can pay their money and take their chances, as with groff's > > grotty(1), for which Lennart Jablonka is preparing patches to make > > the program a terminfo application (at long last, one might say). > > Nicolas has a feature for this which his users can configure :-) I take it you mean that the `Hls` capability that tmux recognizes, we could similarly handle via the user_caps(5) approach? > > We'd like to be able to ask terminfo if the terminal description > > supports OSC 8, but we can't. > > Actually, that's mostly due to Egmont's interference, > as you're probably aware. I actually am not. But I am always interested to hear stories that can inform my expectations of who will be fruitful to work with--or won't. That goes for plagiarists, too. I appreciate your pages documenting your encounters with them. Regards, Branden
