34 ;;; Mike Newton (newton@gumby.cs.caltech.edu) 91.1.24
35 ;;; * bibtex-make-optional-field : modified to make fields align up after
36 ;;; the OPT's have been removed.
37 ;;; * bibtex-make-optional-field : modified to check bibtex-use-OPT-prefix
38 ;;; * bibtex-make*field : modified to call new procedure:
39 ;;; * bibtex-insert-field-delimeters : which does delimeter insertion based on
40 ;;; * bibtex-curly-delimeters : a list of atoms
41 ;;; * fixed spelling of bibtex-name-alignment wherever used
42 ;;; * bibtex-inside-field : allows '}'s at end
43 ;;; * bibtex-find-text : allows '{' and '}'s at start or end
44 ;;; * bibtex-enclosing-regexp fixed for case where start-point was at end of
46 ;;; * bibtex-clean-entry : allow bibtex-save-OPT to save some optional fields
47 ;;; * bibtex-move-outside-of-entry : could overwrite first line of a following
48 ;;; comment or other text if it did not look like a bibtex entry
50 ;;; Mike Newton (newton@gumby.cs.caltech.edu) 91.1.20
51 ;;; * bibtex.el/bibtex-mode : updated comments to indicate new use of
52 ;;; address, add minor explanations and fix small omissions.
53 ;;; * bibtex.el/bibtex-entry : fixed spelling of variable
55 ;;; Mike Newton (newton@gumby.cs.caltech.edu) 90.11.17
56 ;;; * Handle items like
57 ;;; title = poft # "Fifth Tri-quaterly" # random-conf,
58 ;;; and title = {This title is inside curlies}
59 ;;; * added user settable, always present, optional fields
60 ;;; * fixed 'bibtex-find-it's doc string's location
61 ;;; * bibtex-field-text made more general (it wouldnt handle the # construct)
62 ;;; and it now handles a small subset of the {} cases
63 ;;; * put DEA thesis back in (why get rid of good code?)
64 ;;; * merged into release 19 version code
65 ;;; * if cross-ref'ing is on, put 'pages' near top of OPTs, as the other
66 ;;; entries are unlikely to be used.
67 ;;; * skip-whitespace replaced by skip-chars-forward (also done
70 ;;; Bengt Martensson, March 6
71 ;;; Adapted to Bibtex 0.99 by updating the optional fields according
72 ;;; to the document BibTeXing, Oren Patashnik, dated January 31, 1988.
73 ;;; Updated documentation strings accordingly. Added .
74 ;;; If bibtex-include-OPT-crossref is non-nil, every entry will have
75 ;;; an OPTcrossref field, analogously for bibtex-include-OPTkey and
76 ;;; bibtex-include-OPTannote. Added bibtex-preamble, bound to ^C^EP,
77 ;;; and also found in X- and sun-menus. Cleaned up the sun-menu
78 ;;; stuff, and made it more uniform with the X-menu stuff. Marc: I
79 ;;; strongly suspect that I broke your parsing... (Or, more
80 ;;; correctly, BibTeX 0.99 broke it.)
81 ;;; Added bibtex-clean-entry-zap-empty-opts, defvar'd to t. If it
82 ;;; is nil, bibtex-clean-entry will leave empty optional fields alone.
84 ;;; Marc Shapiro 1-feb-89: integrated changes by Bengt Martensson 88-05-06:
85 ;;; Added Sun menu support. Locally bound to right mouse button in
86 ;;; bibtex-mode. Emacs 18.49 allows local mouse bindings!!
87 ;;; Commented out DEAthesis.
89 ;;; Marc Shapiro 6-oct-88
90 ;;; * use indent-to-column instead of inserting tabs (changes to
91 ;;; bibtex-entry, bibtex-make-entry, bibtex-make-OPT-entry, renamed to
92 ;;; bibtex-make-optional-entry)
93 ;;; * C-c C-k deletes the current OPT entry entirely
94 ;;; * C-c C-d replaces text of field with ""
95 ;;; * renamed bibtex-find-it to bibtex-find-text. With arg, now goes to
96 ;;; start of text. Fixed bugs in it.
98 ;;; Marc Shapiro 23-sep-88
99 ;;; * bibtex-clean-entry moves past end of entry.
100 ;;; * bibtex-clean-entry signals mandatory fields left empty.
102 ;;; Marc Shapiro 18-jul-88
103 ;;; * Moved all the entry type keystrokes to "C-c C-e something" (instead of
104 ;;; "C-c something" previously) to make room for more. C-c C-e is
105 ;;; supposed to stand for "entry" [idea taken from mail-mode]. Moved
106 ;;; bibtex-pop-previous to C-c C-p and bibtex-pop-next to C-c C-n.
107 ;;; * removed binding for "\e[25~"
108 ;;; * replaced bibtex-clean-optionals by bibtex-clean-entry, bound to
111 ;;; Marc Shapiro 13-jul-88 [based on ideas by Sacha Krakowiak of IMAG]
112 ;;; * bibtex-pop-previous replaces current field with value of
113 ;;; similar field in previous entry. May be called n times in a row
114 ;;; (or with arg n) to pop similar field of n'th previous entry.
115 ;;; There is also a bibtex-pop-next to get similar field of next
117 ;;; * C-c C-k now kills all empty optional fields of current entry, and
118 ;;; removes "OPT" for those optional fields which have text.
120 ;;; Marc Shapiro 14-dec-87
121 ;;; Cosmetic fixes. Fixed small bug in bibtex-move-outside-of-entry.
122 ;;; Skip Montanaro <steinmetz!sprite!montanaro> 7-dec-87, Shapiro 10-dec-87
123 ;;; before inserting an entry, make sure we are outside of a bib entry
124 ;;; Marc Shapiro 3-nov-87
125 ;;; addition for France: DEAthesis
126 ;;; Marc Shapiro 19-oct-1987
127 ;;; add X window menu option; bug fixes. TAB, LFD, C-c " and C-c C-o now
128 ;;; behave consistently; deletion never occurs blindly.
129 ;;; Marc Shapiro <shapiro@inria.inria.fr> 15-oct-1986
130 ;;; align long lines nicely; C-c C-o checks for the "OPT" string;
