Hrm... maybe if I raise a big enough stink termcap can be installed in
/etc, managed by mergemaster, and everyone will go away happy... me
because I have what I want and everyone else because I finalyl shut up. ;-)
The curses(3X) man page seems to be they key reference. Particularly
the section on environment variables: TERM, TERMCAP, TERMPATH. It does
also mention the possibility of using ${HOME}/.termcap to hold supplementary
termcap entries. However, these man pages are rather confusing: many of them
talk about terminfo(5) in terms of 'it is going to replace termcap(5) any
day now'. But terminfo(5) is a SysV-ism and supported only as a compatibility
thing under FreeBSD.
I'm fairly certain that anything the curses man pages have to say on the
topic is wrong (and I dare you to read the terminfo manpage - it's been
dead on my system for some time... but that's Ok, since it's not
applicable). I believe that *BSD is the only platform using termcap
with ncurses left on the planet. I use termcap(5) as my primary source,
but have a firm belief that the last two thirds of the CAVEATS AND
BUGS section is completely wrong.
Most people will be perfectly happy with the default termcap database -- so
long as it provides xterm / vt100 and cons25 almost all situations are covered.
Yeah.
For your purposes if using environment variables to achieve your ends turns out
not to be workable, then I'd suggest keeping a backup copy of your customised
termcap somewhere where system updates won't overwrite it -- keeping it
in CVS or similar would be a good move -- and writing yourself a little
script to merge in your changes to /usr/share/misc/termcap and then re-run
'cap_mkdb /usr/share/misc/termcap' after a system update. I've a feeling that
/etc/termcap is there mostly for historical compatibility now-adays.
*nod* I've done a basic hack now and plastered stickynotes on all my
systems with dumb terminals. We'll see how well that system works out. :-)
I haven't yet found a way to use env variables (and haven't futzed
around with ~/.termcap yet) with entries in /etc/ttys I suspect it won't
work but I won't know until I beat myself to death with them.

Anyone? What's wrong with just putting your custom termcap entry in /usr/src/share/termcap/termcap.src so it gets installed during installworld? The only issue with doing that is that then I have to manually merge changes or stop using CVSup to update the sources as well as figure out how to exclude a specific file from exact mode in CVSup... or possibly I would need to switch to AnonCVS and pay closer attention to what gets updated. This does present the possibility of a permanent solution (which is good) but seems like a fiendishly large amount of work for what seems to me like a simple task especially considering that this configuration file has been around since the late 70s. Thanks for your input... and hope for a permanent workaround. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Custom termcap entries and installworld
I've now shot myself in the foot at least three times in as many years with custom termcap entries... here's the deal: 1) I modify /etc/termcap and customize a termcap entry for some valid reason (I need 132x42 or whatever for my Link MC/5) 2) I update /etc/gettytab and /etc/ttys accordingly and happily use my dumb terminal on occasion (roughly once per week) 3) I upgrade via sources, being sure to run mergemaster and friends. 4) My terminal stops working. I have now shot myself in the foot and need to recreate the termcap entry (which, silly me, I didn't back up) Now, intellectually, I *know* that termcap is really stored in /usr/share/misc, and that mergemaster doesn't/can't touch those files since they're not configuration files... but every single time I run installworld, I need to take a manual step to keep things working the way they were before. This is a POLA breaker but I've just ignored it every time it happened until now. This time I opened a PR (http://www.freebsd.org/cgi/query-pr.cgi?pr=bin/97407) wishing for mergemaster support which, of course, isn't the Right Thing. So, I suppose my questions are these: 1) How do people cope with custom termcap entries? 2) Is there a *correct* way to cope with custom termcap entries? 3) Is there a good reason to not have /usr/share/misc/termcap be a symlink to /etc/termcap rather than the reverse which would allow mergemaster to Just Work? that is... putting it in /etc fixes a problem... does moving it create one or more more serious problems? 4) Am I supposed to submit every custom termcap tweak for inclusion in the next release so I can keep using my terminals? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
