You're right, installing the terminfo entries as stnew works (if the
terminal name is changed as well)! I grepped the sources a bit, and
found this file:
/usr/src/lib/libcurses/tinfo/read_bsd_terminfo.c
In there, you find a hardcoded string pointing to the nonexistent file:
#define _PATH_TERMINFO "/usr/share/misc/terminfo"
and this function:
int
_nc_read_bsd_terminfo_entry(tn, filename, tp)
const char *const tn;
char *const filename;
TERMTYPE *const tp;
{
char **fname, *p;
char envterm[PATH_MAX]; /* local copy of $TERMINFO */
char hometerm[PATH_MAX]; /* local copy of $HOME/.terminfo */
char *pathvec[4]; /* list of possible terminfo files */
size_t len;
fname = pathvec;
/* $TERMINFO may hold a path to a terminfo file */
if (use_terminfo_vars() && (p = getenv("TERMINFO")) != NULL) {
len = strlcpy(envterm, p, sizeof(envterm));
if (len < sizeof(envterm))
*fname++ = envterm;
}
/* Also check $HOME/.terminfo if it exists */
if (use_terminfo_vars() && (p = getenv("HOME")) != NULL && *p != '\0') {
len = snprintf(hometerm, sizeof(hometerm), "%s/.terminfo", p);
if (len > 0 && len < sizeof(hometerm))
*fname++ = hometerm;
}
/* Finally we check the system terminfo file */
*fname++ = _PATH_TERMINFO;
*fname = NULL;
/*
* Lookup ``tn'' in each possible terminfo file until
* we find it or reach the end.
*/
for (fname = pathvec; *fname; fname++) {
if (_nc_lookup_bsd_terminfo_entry(tn, *fname, tp) == 1) {
/* Set copyout parameter and return */
(void)strlcpy(filename, *fname, PATH_MAX);
return (1);
}
}
return (0);
}
If i understand correctly, this program is used to read terminfo files
and to lookup entries later, though i have no idea how it is done. From
this code, it seems that a dir given with TERMINFO and ~/.terminfo are
checked as well, but always *before* the systemwide db is checked, and
therefore, all previous entries are overridden if the same terminal id
is found there in the system db. Maybe changing the order of checks will
allow entries in ~ to dominate entries from the system db, and even
though i don't really know what i'm doing, i think i will try it out and
see if it helps :)
Best,
Nils
