Another thing that should be fixed is the mouse-menu ;;:: support, but who knows what it will look like in version 19; at least ;;:: not in such a place like this... ;;:: ;;:: Feel free to modify and/or forward to FSF. ;;:: ;;; BibTeX mode for GNU Emacs ;;; Bengt Martensson, March 6 ;;; Adapted to Bibtex 0.99 by updating the optional fields according ;;; to the document BibTeXing, Oren Patashnik, dated January 31, 1988. ;;; Updated documentation strings accordingly. Added (provide 'bibtex). ;;; If bibtex-include-OPT-crossref is non-nil, every entry will have ;;; an OPTcrossref field, analogously for bibtex-include-OPTkey and ;;; bibtex-include-OPTannote. Added bibtex-preamble, bound to ^C^EP, ;;; and also found in X- and sun-menus. Cleaned up the sun-menu ;;; stuff, and made it more uniform with the X-menu stuff. Marc: I ;;; strongly suspect that I broke your parsing... (Or, more ;;; correctly, BibTeX 0.99 broke it.) ;;; Added bibtex-clean-entry-zap-empty-opts, defvar'd to t. If it ;;; is nil, bibtex-clean-entry will leave empty optional fields alone. ;;; Marc Shapiro 1-feb-89: integrated changes by Bengt Martensson 88-05-06: ;;; Added Sun menu support. Locally bound to right mouse button in ;;; bibtex-mode. Emacs 18.49 allows local mouse bindings!! ;;; Commented out DEAthesis. ;;; Marc Shapiro 6-oct-88 ;;; * skip-whitespace replaced by skip-chars-forward ;;; * use indent-to-column instead of inserting tabs (changes to ;;; bibtex-entry, bibtex-make-entry, bibtex-make-OPT-entry, renamed to ;;; bibtex-make-optional-entry) ;;; * C-c C-k deletes the current OPT entry entirely ;;; * C-c C-d replaces text of field with "" ;;; * renamed bibtex-find-it to bibtex-find-text. With arg, now goes to ;;; start of text. Fixed bugs in it. ;;; Marc Shapiro 23-sep-88 ;;; * bibtex-clean-entry moves past end of entry. ;;; * bibtex-clean-entry signals mandatory fields left empty. ;;; Marc Shapiro 18-jul-88 ;;; * Fixed bug in bibtex-flash-entry ;;; * Moved all the entry type keystrokes to "C-c C-e something" (instead of ;;; "C-c something" previously) to make room for more. C-c C-e is ;;; supposed to stand for "entry" [idea taken from mail-mode]. Moved ;;; bibtex-pop-previous to C-c C-p and bibtex-pop-next to C-c C-n. ;;; * removed binding for "\e[25~" ;;; * replaced bibtex-clean-optionals by bibtex-clean-entry, bound to ;;; C-c C-c ;;; Marc Shapiro 13-jul-88 [based on ideas by Sacha Krakowiak of IMAG] ;;; * bibtex-pop-previous replaces current field with value of ;;; similar field in previous entry. May be called n times in a row ;;; (or with arg n) to pop similar field of n'th previous entry. ;;; There is also a bibtex-pop-next to get similar field of next ;;; entry. ;;; * C-c C-k now kills all empty optional fields of current entry, and ;;; removes "OPT" for those optional fields which have text. ;;; Marc Shapiro 14-dec-87 ;;; Cosmetic fixes. Fixed small bug in bibtex-move-outside-of-entry. ;;; Skip Montanaro 7-dec-87, Shapiro 10-dec-87 ;;; before inserting an entry, make sure we are outside of a bib entry ;;; Marc Shapiro 3-nov-87 ;;; addition for France: DEAthesis ;;; Marc Shapiro 19-oct-1987 ;;; add X window menu option; bug fixes. TAB, LFD, C-c " and C-c C-o now ;;; behave consistently; deletion never occurs blindly. ;;; Marc Shapiro 15-oct-1986 ;;; align long lines nicely; C-c C-o checks for the "OPT" string; ;;; TAB goes to the end of the string; use lower case; use ;;; run-hooks ;;; Bengt Martensson 87-06-28 ;;; Original version ;;; NOTE by Marc Shapiro, 14-dec-87: ;;; (bibtex-x-environment) binds an X menu for bibtex mode to x-button-c-right. ;;; Trouble is, in Emacs 18.44 you can't have a mode-specific mouse binding, ;;; so it will remain active in all windows.
