Hmmm ... seems to me that the sane behavior with an unrecognized tag
is
not to match on it. that way, an instantiator tagged with "msprinter"
will never apply on X windows, which is probably what you want.
i'm not totally averse to removing the error on unknown tags. i imagine
i put in the error on the principle that misspellings should be flagged
rather than silently ignored ... but i wasn't considering the situation
Aidan mentions. maybe in its place a warning could be issued, at the
same level as current warnings about unrecognized font/color/etc
names. (OTOH you can pretty easily define something like `msprinter'
unilaterally in all circumstances, even on a non-MSWindows ...)
Right, I’ve done that--the misspellings point is important. Thanks for your
input!
APPROVE COMMIT
NOTE: This patch has been committed.
lisp/ChangeLog addition:
2007-09-30 Aidan Kehoe <kehoea(a)parhasard.net>
* x-faces.el:
* x-faces.el ('x-resource)): Removed.
Specifier tag moved to specifier.el to ensure availability on
non-X builds.
* specifier.el:
Provide x, tty, mswindows, msprinter, gtk and carbon as device
tags that never match on builds that don't support them.
* specifier.el ('x-resource)): New.
Moved here from x-faces.el

On the quay of the little Black Sea port, where the rescued pair came once
more into contact with civilization, Dobrinton was bitten by a dog which was
assumed to be mad, though it may only have been indiscriminating. (Saki)
