Re: ignores frame font specification [Re: [COMMIT] Provide a FORCE argument in set-charset-registries]

Ar an t-ochtú lá déag de mí na Nollaig, scríobh Ilya N. Golubev: I don’t regard the current behaviour as a problem, and I’ve no intention of changing what it does. I may better _document_ what it does, if you find it currently very unclear. The FORCE argument to set-face-font is only relevant when you’re dealing with X fonts that don’t follow the XLFD convention. We discussed this at some length. If, as you are, you’re dealing with fonts that do follow the XLFD convention, then you can specify an actual REGISTRY-ENCODING combination for the charset in question, and you should call: (set-charset-registries 'ascii (apply 'vector "koi8-r" (append (charset-registries 'ascii) nil))) instead of using the FORCE argument. The specification wasn’t ignored. Previously, the code was very dumb with regard to the registry and encoding passed to XListFonts. If in 21.4 you evaluate the following: (progn (set-charset-registry 'cyrillic-iso8859-5 "koi8-r") (set-charset-ccl-program 'cyrillic-iso8859-5 ccl-encode-koi8-r-font)) without any XEmacs-relevant X resources set it will run XListFonts on all of the following patterns: "-*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-*" "-*-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-*" "-*-courier-*-r-*-*-*-120-*-*-*-*-iso8859-*" "-*-*-medium-r-*-*-*-120-*-*-m-*-iso8859-*" "-*-*-medium-r-*-*-*-120-*-*-c-*-iso8859-*" "-*-*-*-r-*-*-*-120-*-*-m-*-iso8859-*" "-*-*-*-r-*-*-*-120-*-*-c-*-iso8859-*" "-*-*-*-r-*-*-*-120-*-*-*-*-iso8859-*" And check every single one of each of the results against the regexp "koi8-r". Despite that, were the regexp "koi8-r" to match, it would be for the wrong reasons (the weight would have to be "koi8"), so all that checking is a waste of time. The new code looks at a given font pattern and uses the charset-registries vector to pass a manipulated pattern to XListFonts. This means a pattern ending in koi8-r will only be used for a given charset if XEmacs is aware such a pattern can be approprate for that charset. You can make XEmacs aware that such a pattern can be appropriate for that charset using the set-charset-registries call above. Be aware that the order of the charset-registries matters; (set-charset-registries 'ascii ["koi8-r" "iso8859-1"]) with your pattern gives me a different font on the frame in question than: (set-charset-registries 'ascii ["iso8859-1" "koi8-r"]) Working with your X resources, and 21.4 with Mule, I don’t get any sensible results--that is, the koi8-r font is never used for cyrillic-iso8859-5 or latin-iso8859-1. Are there parts of your configuration that you’re omitting? The new font instancing routines implement the documented specifier instancing rules. They do not implement all the detail of the behaviour of the previous specifier instancing rules, because those rules were not any more powerful than the current ones, but were significantly slower and less intuitive to humans. (E.g. if a face used an explicitly specified X11 font for ISO 8859 1, it did not necessarily prefer the ISO 8859 2 variant of the same font to display ISO 8859 2.) Sure. But the old code didn’t do it--that is, it didn’t allow non-XLFD fonts to be specified for control-1 and latin-iso8859-1--and I think it’s a waste of time to implement such a thing. I implemented it for ASCII for two reasons, despite also thinking it a waste of time; because the old code did it, so this made migration easier, and because you evidently felt strongly about it. (if (fboundp 'set-charset-registries) (progn ;; Do the manipulation specific to the new model here ) ;; else do the manipulation specific to the new model. (set-charset-registry ....) ) As Lisp code goes, that’s pretty clear and intuitive. Don’t ever load cl-macs.el if you would find that obscure :-) . Fuck no! The argument is no longer a regular expression, and it only matches at the end. I want people to be very uncomfortable using set-charset-registry with the new font instancing rules; that’s what the warning’s there for. -- When I was in the scouts, the leader told me to pitch a tent. I couldn't find any pitch, so I used creosote. _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
