|
||
|
||
;;; Change Log:
|
||
|
||
;;; alarson@src.honeywell.com 92-Jan-31
|
||
;;; Added support for: ispell, beginning/end of entry movement, a simple
|
||
;;; outline like mode (hide the bodies of bibtex entries), support for
|
||
;;; sorting bibtex entries, and maintaining them in sorted order, and
|
||
;;; simple buffer validation.
|
||
;;; User visible functions added:
|
||
;;; ispell-{abstract,bibtex-entry}, {beginning,end}-of-bibtex-entry
|
||
;;; hide-bibtex-entry-bodies, sort-bibtex-entries, validate-bibtex-
|
||
;;; buffer, find-bibtex-duplicates
|
||
;;; user visible variables added:
|
||
;;; bibtex-maintain-sorted-entries
|
||
;;; new local keybindings:
|
||
;;; " TeX-insert-quote
|
||
;;; C-c$ ispell-bibtex-entry
|
||
;;; M-C-a beginning-of-bibtex-entry
|
||
;;; M-C-e end-of-bibtex-entry
|
||
;;; Mike Newton (newton@gumby.cs.caltech.edu) 90.11.17
|
||
;;; * Handle items like
|
||
;;; title = poft # "Fifth Tri-quaterly" # random-conf,
|
||
;;; and title = {This title is inside curlies}
|
||
;;; * added user settable, always present, optional fields
|
||
;;; * fixed 'bibtex-find-it's doc string's location
|
||
;;; * bibtex-field-text made more general (it wouldnt handle the # construct)
|
||
;;; and it now handles a small subset of the {} cases
|
||
|
||
;;; 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 <steinmetz!sprite!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 <shapiro@inria.inria.fr> 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

double-quotes from entirely numerical fields, (ii) removes OPT from all

non-empty optional fields, (iii) removes all empty optional fields, and (iv)

\\[bibtex-x-environment] binds a mode-specific X menu to control+right
