|
37 ;; VMS: I have no clue if this works under VMS. I don't know how emacs handle

|
|
|
62 ;; Description:
|
|
|
63 ;; ~~~~~~~~~~~
|
|
|
64 ;; This package is used in various TeX modes to display or edit references
|
|
|
65 ;; associated with \cite commands, or matching \ref and \label commands.
|
|
|
66 ;; (so I actually overstep BiBTeX bounds here...)
|
|
|
67 ;; These are the functions:
|
|
|
68 ;;
|
|
|
69 ;; bib-display bib-display-mouse
|
|
|
70 ;; - Display citation, \ref or \label under point
|
|
|
71 ;; bib-find bib-find-mouse
|
|
|
72 ;; - Edit citation, \ref or \label under point
|
|
|
73 ;; bib-make-bibliography - Make BiBTeX file containing only cite keys used.
|
|
|
74 ;; bib-apropos - Search BiBTeX source files for keywords.
|
|
|
75 ;; bib-etags - Refreshes (or builds) the TAGS files for
|
|
|
76 ;; multi-file documents.
|
|
|
77 ;; bib-create-auto-file - Used in bibtex-mode to create cite key
|
|
|
78 ;; completion .el file for auctex.
|
|
|
79 ;; bib-highlight-mouse - Highlight \cite, \ref and \label commands in
|
|
|
80 ;; green when the mouse is over them.
|
|
|
81
|
|
|
82 ;; About Cite Commands and related functions:
|
|
|
83 ;; ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
84 ;; Various flavors of \cite commands are allowed (as long as they contain
|
|
|
85 ;; the word `cite') and they may optionally have bracketed [] options.
|
|
|
86 ;; Bibtex Cross-references are displayed, and @string abbreviations are
|
|
|
87 ;; substituted or included.
|
|
|
88 ;;
|
|
|
89 ;; The \cite text is found (by emacs) in the bibtex source files listed in the
|
|
|
90 ;; \bibliography command. The BiBTeX files can be located in a search path
|
|
|
91 ;; defined by an environment variable (typically BIBINPUTS, but you can change
|
|
|
92 ;; this).
|
|
|
93 ;;
|
|
|
94 ;; All citations used in a buffer can also be listed in a new bibtex buffer by
|
|
|
95 ;; using bib-make-bibliography. This is useful to make a bibtex file for a
|
|
|
96 ;; document from a large bibtex database. In this case, cross-references are
|
|
|
97 ;; included, as well as the @string commands used. The @string abbreviations
|
|
|
98 ;; are not substituted.
|
|
|
99 ;;
|
|
|
100 ;; The bibtex files can also be searched for entries matching a regular
|
|
|
101 ;; expression using bib-apropos.
|
|
|
102
|
|
|
103 ;; Usage instructions:
|
|
|
104 ;; ~~~~~~~~~~~~~~~~~~
|
|
|
105 ;; bib-display Bound to Mouse-3 when specially highlighted.
|
|
|
106 ;; In Hyperbole, bound to the Assist key.
|
|
|
107 ;; Bound to `\C-c b d'
|
|
|
108 ;;
|
|
|
109 ;; bib-display will show the bibtex entry or the corresponding label or
|
|
|
110 ;; ref commands from anywhere within a document.
|
|
|
111 ;; With cursor on the \cite command itslef
|
|
|
112 ;; -> display all citations of the cite command from the BiBTeX source.
|
|
|
113 ;; With cursor on a particular cite key within the brackets
|
|
|
114 ;; -> display that citation's text from the BiBTeX source file(s).
|
|
|
115 ;;
|
|
|
116 ;; Example:
|
|
|
117 ;;
|
|
|
118 ;; \cite{Wadhams81,Bourke.et.al87,SchneiderBudeus94}
|
|
|
119 ;; ^Cursor -> Display-all-citations ^Cursor -> Display-this-citation
|
|
|
120 ;;
|
|
|
121 ;; With cursor on a \label command
|
|
|
122 ;; -> Display first matching \ref command in the document
|
|
|
123 ;; With cursor on a \ref command
|
|
|
124 ;; -> Display environment associated with the matching \label command.
|
|
|
125 ;;
|
|
|
126 ;; Finding a ref or label within a multi-file document requires a TAGS file,
|
|
|
127 ;; which is automatically generated for you. This enables you to then use
|
|
|
128 ;; any tags related emacs features.
|
|
|
129 ;;
|
|
|
130 ;; bib-find Bound to Mouse-2 when specially highlighted.
|
|
|
131 ;; In Hyperbole, bound to the Action key.
|
|
|
132 ;; Bound to `\C-c b f'
|
|
|
133 ;;
|
|
|
134 ;; bib-find will select the buffer and move point to the BiBTeX source file
|
|
|
135 ;; at the proper citation for a cite command, or move point to anywhere
|
|
|
136 ;; within a document for a label or ref command. The ref chosen is the
|
|
|
137 ;; first occurrance within a document (using a TAGS file). If point is
|
|
|
138 ;; moved within the same buffer, mark is set before the move and a message
|
|
|
139 ;; stating so is given. If point is moved to another file, this is done in
|
|
|
140 ;; a new window using tag functions. Within a plain file, the search
|
|
|
141 ;; pattern is set for another similar \ref command (since TAGS file are not
|
|
|
142 ;; used). Within a multi-file document the following tag functions are
|
|
|
143 ;; appropriately setup:
|
|
|
144 ;;
|
|
|
145 ;; C-u M-. Find next alternate definition of last tag specified.
|
|
|
146 ;;
|
|
|
147 ;; C-u - M-. Go back to previous tag found.
|
|
|
148 ;;
|
|
|
149 ;;
|
|
|
150 ;; For multi-file documents, you must be using auctex (so that bib-cite can
|
|
|
151 ;; find the master file) and all \input and \include commands must be first
|
|
|
152 ;; on a line (not preceeded by any non-white text).
|
|
|
153 ;;
|
|
|
154 ;; imenu support (Suggested key binding: Shift-Mouse-3)
|
|
|
155 ;;
|
|
|
156 ;; If you want to bind imenu globally to Shift-Mouse-3, do so by adding the
|
|
|
157 ;; following to your ~/.emacs
|
|
|
158 ;;
|
|
|
159 ;; (require 'imenu)
|
|
|
160 ;; (define-key global-map [S-mouse-3] 'imenu)
|
|
|
161 ;;
|
|
|
162 ;; Another good place to define Imenu is in the menu-bar. You can try this
|
|
|
163 ;; manually with
|
|
|
164 ;;
|
|
|
165 ;; M-x imenu-add-to-menubar RET Imenu RET
|
|
|
166 ;;
|
|
|
167 ;; or in a hook such as:
|
|
|
168 ;;
|
|
|
169 ;; (add-hook 'LaTeX-mode-hook '(lambda () (imenu-add-to-menubar "Imenu")))
|
|
|
170 ;;
|
|
|
171 ;; The imenu facility (distributed with emacs) is supported by bib-cite to
|
|
|
172 ;; move point to a LaTeX section (or chapter) division or to a label
|
|
|
173 ;; declaration. When editing a multi-file document, all such declarations
|
|
|
174 ;; within the document are displayed in the menu (again using a TAGS file).
|
|
|
175 ;; If you do not want to load imenu.el and use these features, set
|
|
|
176 ;; bib-use-imenu to nil. (This feature is disabled in xemacs because I'm
|
|
|
177 ;; told it doesn't have imenu).
|
|
|
178 ;;
|
|
|
179 ;; bib-make-bibliography: Bound to `\C-c b m'
|
|
|
180 ;;
|
|
|
181 ;; Extract citations used in the current document from the \bibliography{}
|
|
|
182 ;; file(s). Put them into a new suitably-named buffer. In a auctex
|
|
|
183 ;; multi-file document, the .aux files are used to find the cite keys (for
|
|
|
184 ;; speed). You will be warned if these are out of date.
|
|
|
185 ;;
|
|
|
186 ;; This buffer is not saved to a file. It is your job to save it to whatever
|
|
|
187 ;; name you wish. Note that auctex has a unique name space for LaTeX and
|
|
|
188 ;; BiBTeX files, so you should *not* name the bib file associated with
|
|
|
189 ;; example.tex as example.bib! Rather, name it something like
|
|
|
190 ;; example-bib.bib.
|
|
|
191 ;;
|
|
|
192 ;; bib-apropos: Bound to `\C-c b a'
|
|
|
193 ;;
|
|
|
194 ;; Searches the \bibliography{} file(s) for entries containing a keyword and
|
|
|
195 ;; display them in the *help* buffer. You can trim down your search by using
|
|
|
196 ;; bib-apropos in the *Help* buffer after the first invocation. the current
|
|
|
197 ;; buffer is also searched for keyword matches if it is in bibtex-mode.
|
|
|
198 ;;
|
|
|
199 ;; It doesn't display cross-references nor does it substitute or display
|
|
|
200 ;; @string commands used. It could easily be added, but it's faster this
|
|
|
201 ;; way. Drop me a line if this would be a useful addition.
|
|
|
202 ;;
|
|
|
203 ;; If you find yourself entering a cite command and have forgotten which key
|
|
|
204 ;; you want, but have entered a few initial characters as in `\cite{Gal',
|
|
|
205 ;; then invoke bib-apropos. It will take that string (in this case `Gal') as
|
|
|
206 ;; an initial response to the apropos prompt. You are free to edit it, or
|
|
|
207 ;; simply press carriage return.
|
|
|
208 ;;
|
|
|
209 ;; bib-etags: Bound to `\C-c b e'
|
|
|
210 ;;
|
|
|
211 ;; Creates a TAGS file for auc-tex's multi-file document (or refreshes it).
|
|
|
212 ;; This is used by bib-find when editing multi-file documents. The TAGS file
|
|
|
213 ;; is created automatically, but it isn't refreshed automatically. So if
|
|
|
214 ;; bib-find can't find something, try running bib-etags again. The *rescan*
|
|
|
215 ;; in imenu also calls bib-etags to refresh the TAGS file, so that is another
|
|
|
216 ;; way to generate it.
|
|
|
217 ;;
|
|
|
218 ;; bib-create-auto-file:
|
|
|
219 ;;
|
|
|
220 ;; Use this when editing a BiBTeX buffer to generate the auc-tex .el file
|
|
|
221 ;; which tell emacs about all its cite keys. I've added this command to
|
|
|
222 ;; bibtex-mode pull-down menu.
|
|
|
223 ;;
|
|
|
224 ;; bib-highlight-mouse: Bound to `\C-c b h'
|
|
|
225 ;;
|
|
|
226 ;; Highlights \cite, \ref and \label commands in green when the mouse is over
|
|
|
227 ;; them. By default, a call to this function is added to LaTeX-mode-hook
|
|
|
228 ;; (via bib-cite-initialize) if you set bib-highlight-mouse-t to true. But
|
|
|
229 ;; you may want to run this command to refresh the highlighting for newly
|
|
|
230 ;; edited text.

232 ;; Installation instructions:
|
|
|
233 ;; ~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
234 ;; If you use a menued environment (e.g. X Window System), bib-cite must be
|
|
|
235 ;; loaded *after* your LaTeX-mode menus are created in order to bypass an
|
|
|
236 ;; annoying bug in bib-cite. This is done by loading bib-cite via a
|
|
|
237 ;; mode-hook:
|
|
|
238 ;; - If you are using AUC-TeX (http://sunsite.auc.dk/auctex/), add the
|
|
|
239 ;; following lines to your ~/.emacs file:
|
|
|
240 ;;
|
|
|
241 ;; (defun my-LaTeX-mode-hook ()
|
|
|
242 ;; (require 'bib-cite))

|
243 ;; (add-hook 'LaTeX-mode-hook 'my-LaTeX-mode-hook)
|
|
|
244 ;;
|
|
|
245 ;; - If you are using Emacs' regulare LaTeX-mode, use instead:
|
|
|
246 ;;
|
|
|
247 ;; (defun my-LaTeX-mode-hook ()
|
|
|
248 ;; (require 'bib-cite))
|
|
|
249 ;; (add-hook 'latex-mode-hook 'my-TeX-mode-hook)
|
|
|
250 ;;
|
|
|
251 ;; If you do not use a windowed environment, all you need to do is add this
|
|
|
252 ;; line to your .emacs file:
|
|
|
253 ;;
|
|
|
254 ;; (require 'bib-cite)
|
|
|
255 ;;
|
|
|
256 ;; bib-cite can be used with auctex, or stand-alone. If used with auctex on a
|
|
|
257 ;; multi-file document (and auctex's parsing is used), then all \bibliography
|
|
|
258 ;; commands in the document will be found and used.
|
|
|
259 ;; ---
|
|
|
260 ;; The following variable can be unset (like shown) to tell bib-cite to

|
|
262 ;; occurrence of a search:
|
|
|
263 ;;
|
|
|
264 ;; (setq bib-novice nil)
|
|
|
265 ;; ---
|
|
|
266 ;; By default, bib-cite adds a menu-bar pull-down menu under a separate name.
|
|
|
267 ;; Under emacs' tex-mode and auctex's latex-mode, it can be placed within
|
|
|
268 ;; the existing menu if you set the following:
|
|
|
269 ;;
|
|
|
270 ;; (setq bib-cite-put-menu-separately nil)
|

288 ;; The variable bib-switch-to-buffer-function sets the function used to
|
|

352 ;; (and use auctex's completion list)
|
|
|
353 ;; - implement string concatenation, with #[ \t\n]*STRING_NAME
