* overlay start/end marker access funs? @ 2002-03-12 2:51 Miles Bader 2002-03-12 18:07 ` Stefan Monnier 2002-03-12 20:29 ` Richard Stallman 0 siblings, 2 replies; 3+ messages in thread From: Miles Bader @ 2002-03-12 2:51 UTC (permalink / raw) I wanted to augment `describe-text-at' to print the start/end insertion-types of overlays, but there doesn't seem to be any way to actually get that info in elisp. So, I thought it might be nice to add `overlay-start-marker'and `overlay-end-marker' access functions -- then one could use `marker-insertion-type' to do what I want. Does anyone see a problem with allowing elisp access to these markers? (or is there one already, and I'm missing it?) [If there is a problem, I guess something like `overlay-start-insertion-type' and `overlay-end-insertion-type' would be OK, then.] Thanks, -Miles -- 97% of everything is grunge _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://mail.gnu.org/mailman/listinfo/emacs-devel ^ permalink raw reply [flat|nested] 3+ messages in thread

So I agree it would be good to have.

(or is there one already, and I'm missing it?) That would make it possible to call move-marker on them, which would mess up the overlay data structure. So it would be better to add a function that only provides access to the insertion types. _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://mail.gnu.org/mailman/listinfo/emacs-devel ^ permalink raw reply [flat|nested] 3+ messages in thread
