Re: port x-symbol to GNU emacs 24.

Uwe Brauer writes: AFAIK you're the only user left, and you've spent quite a bit of time, both yours and others', on trying to keep this code working (which was idiosyncratic when written, to say the least). I'm giving up. This is my last post, ever, on x-symbol (except if necessary to veto changes to XEmacs :-/ ). Extents are a unification[1] of Emacs's overlays and text properties, with a similar API. Most likely you want to use the text property API rather than the overlay API. Specifiers are a unification and generalization of buffer-local and frame-local variables[2], but with a rather different API that has to be invoked explicitly to reference and mutate them, rather than being a special type of variable that is referenced and mutated in the usual way. I suppose that you can probably ignore the specifier stuff, however, and just use Customize to define the appropriate faces (defface) which are selected for the x-symbol charset. Another problem you'll run into in more recent GNU Emacs is that the internal encoding (a UTF-8 extension) no longer has charsets in the sense that Mule encoding did, as part of each character. So you will need to define a charset to hold the x-symbol characters (a Unicode block, possibly in Unicode private space but perhaps outside of the official range of Unicode scalars) using an API that is not relevant to XEmacs, I suspect. Note that it's probably possible to achieve what x-symbol does in 1/5 the code and without defining a new charset or glyphs by simply taking advantage of the fact that most (all?) of those symbols are already in Unicode. I believe there are TeX add-ons that allow you to use them instead of the traditional macros, as well, so you might not even need to fiddle the display of the TeX file at all, and x-symbol would be completely irrelevant. Footnotes: [1] IIRC, there's a corner case involving text properties that can't be properly simulated using only extent properties, but it's otherwise equivalent. [2] ISTR frame-locals have been deprecated or removed in recent Emacs? _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://lists.xemacs.org/mailman/listinfo/xemacs-beta
