Message-ID: <m2efqi1lwt.wl%esq@lawlist.com> (raw)
Thank you, Eli, for looking at this particular thread. The first draft of crosshairs is taking me longer than I had initially anticipated, and I still have not played with implementing that functionality for Emacs flavors W32 or X11. So, it may be awhile before I have a draft ready. In the meantime, I ported from Lisp to C the functions `face-attribute` (except the condition-case) and `face-attribute-merged-with':
https://lists.gnu.org/archive/html/emacs-devel/2017-09/msg00917.html
My preference is that multiple fake cursors and crosshairs be implemented entirely in C, with just a little bit of Lisp to access those tools. I also felt that relying on Lisp might somehow slow things down a bit, and speed is really important.
If you or anyone is interested in adding `face-attribute` and `face-attribute-merged-with' to xfaces.c, the link above has my suggested implementation.
Keith
