28 | ;; |
29 | ;; RefTeX is a minor mode with distinct support for \ref, \label, \cite, | |
30 | ;; and \index commands in (multi-file) LaTeX documents. | |
f9ad2e24 CD |
31 | ;; - A table of contents provides easy access to any part of a document. |
32 | ;; - Labels are created semi-automatically. | |
33 | ;; - Definition context of labels is provided when creating a reference. | |
34 | ;; - Citations are simplified with efficient database lookup. | |
1c25ed90 | 35 | ;; - The index preview buffer helps to check and edit index entries. |

38 | ;; INSTALLATION |
39 | ;; ------------ | |
40 | ;; | |
f9ad2e24 CD |
41 | ;; - If this file is part of an X/Emacs distribution, it is installed. |
42 | ;; - For XEmacs 21.x, you need to install the RefTeX plug-in package | |
43 | ;; available from the XEmacs distribution sites. | |
44 | ;; - If you have downloaded this file from the maintainers webpage, follow | |
45 | ;; the instructions in the INSTALL file of the distrubution. | |
a6611c0d | 46 | ;; |
f9ad2e24 | 47 | ;; To turn RefTeX Mode on and off in a buffer, use `M-x reftex-mode'. |
a7ec1775 | 48 | ;; |
f9ad2e24 CD |
49 | ;; To turn on RefTeX Mode for all LaTeX files, add the following lines |
50 | ;; to your .emacs file: | |
a7ec1775 | 51 | ;; |
f9ad2e24 CD |
52 | ;; (add-hook 'LaTeX-mode-hook 'turn-on-reftex) ; AUCTeX LaTeX mode |
53 | ;; (add-hook 'latex-mode-hook 'turn-on-reftex) ; Emacs latex mode | |

56 | ;; DOCUMENTATION |
57 | ;; ------------- | |
396e0b08 | 58 | ;; |
a6611c0d CD |
59 | ;; See below for a short summary of how to use RefTeX. |
60 | ;; | |
2faef409 | 61 | ;; There is an extensive texinfo document describing RefTeX in detail. |
f9ad2e24 | 62 | ;; One way to view this documentation is `M-x reftex-info RET'. |
a7ec1775 | 63 | ;; |
a6611c0d | 64 | ;; The documentation in various formats is also available at |

70 | ;; RefTeX in a Nutshell |
71 | ;; ==================== | |
921759ee | 72 | ;; |
f9ad2e24 CD |
73 | ;; 1. Table of Contents |
74 | ;; Typing `C-c =' (`reftex-toc') will show a table of contents of the | |
1c25ed90 CD |
75 | ;; document. This buffer can display sections, labels and index |
76 | ;; entries defined in the document. From the buffer, you can jump | |
77 | ;; quickly to every part of your document. Press `?' to get help. | |
921759ee | 78 | ;; |
f9ad2e24 | 79 | ;; 2. Labels and References |
1c25ed90 CD |
80 | ;; RefTeX helps to create unique labels and to find the correct key |
81 | ;; for references quickly. It distinguishes labels for different | |
82 | ;; environments, knows about all standard environments (and many | |
83 | ;; others), and can be configured to recognize any additional labeled | |
84 | ;; environments you have defined yourself (variable | |
85 | ;; `reftex-label-alist'). | |
86 | ;; | |
87 | ;; * Creating Labels | |
88 | ;; Type `C-c (' (`reftex-label') to insert a label at point. | |
89 | ;; RefTeX will either | |
90 | ;; - derive a label from context (default for section labels) | |
91 | ;; - prompt for a label string (default for figures and | |
92 | ;; tables) or | |
93 | ;; - insert a simple label made of a prefix and a number (all | |
94 | ;; other environments) | |
95 | ;; | |
96 | ;; Which labels are created how is configurable with the variable | |
97 | ;; `reftex-insert-label-flags'. | |
98 | ;; | |
99 | ;; * Referencing Labels | |
100 | ;; To make a reference, type `C-c )' (`reftex-reference'). This | |
101 | ;; shows an outline of the document with all labels of a certain | |
102 | ;; type (figure, equation,...) and some label context. | |
103 | ;; Selecting a label inserts a `\ref{LABEL}' macro into the | |
104 | ;; original buffer. | |
105 | ;; | |
f9ad2e24 CD |
106 | ;; 3. Citations |
107 | ;; Typing `C-c [' (`reftex-citation') will let you specify a regular | |
108 | ;; expression to search in current BibTeX database files (as | |
109 | ;; specified in the `\bibliography' command) and pull out a list of | |
110 | ;; matches for you to choose from. The list is *formatted* and | |
111 | ;; sorted. The selected article is referenced as `\cite{KEY}' (see | |
1c25ed90 CD |
112 | ;; the variable `reftex-cite-format' if you want to insert different |
113 | ;; macros). | |
114 | ;; | |
115 | ;; 4. Index Support | |
116 | ;; RefTeX helps to enter index entries. It also compiles all entries | |
117 | ;; into an alphabetically sorted `*Index*' buffer which you can use | |
118 | ;; to check and edit the entries. RefTeX knows about the standard | |
119 | ;; index macros and can be configured to recognize any additional | |
120 | ;; macros you have defined (`reftex-index-macros'). Multiple indices | |
121 | ;; are supported. | |
122 | ;; | |
123 | ;; * Creating Index Entries | |
124 | ;; Type `C-c /' (`reftex-index-selection-or-word') to index the | |
125 | ;; current selection or the word at the cursor with the default | |
126 | ;; macro (see the variable `reftex-index-default-macro'). | |
127 | ;; Type `C-c <' (`reftex-index') to insert a general index macro. | |
128 | ;; RefTeX will offer a list of available macros and provide | |
129 | ;; completion for the index tag (used to identify one of | |
130 | ;; multiple indices) and for the entry itself (useful with | |
131 | ;; subentries). | |
132 | ;; | |
133 | ;; * Displaying the Index | |
134 | ;; To display the compiled index in a special buffer, type `C-c | |
135 | ;; >' (`reftex-display-index'). From that buffer you can check | |
136 | ;; and edit all entries. The index can be restricted to those | |
137 | ;; entries defined in a single document section or in a user | |
138 | ;; defined region. | |
139 | ;; | |
140 | ;; 5. Viewing Cross-References | |
921759ee CD |
141 | ;; When point is on the KEY argument of a cross-referencing macro |
142 | ;; (`\label', `\ref', `\cite', `\bibitem', `\index', and variations) | |
143 | ;; or inside a BibTeX database entry, you can press `C-c &' | |
144 | ;; (`reftex-view-crossref') to display corresponding locations in the | |
145 | ;; document and associated BibTeX database files. | |
146 | ;; When the enclosing macro is `\cite' or `\ref' and no other message | |
147 | ;; occupies the echo area, information about the citation or label | |
1c25ed90 CD |
148 | ;; will automatically be displayed in the echo area. |
149 | ;; | |
150 | ;; 6. Multifile Documents | |
151 | ;; Multifile Documents are fully supported. The included files must | |
152 | ;; have a file variable `TeX-master' or `tex-main-file' pointing to | |
153 | ;; the master file. RefTeX provides cross-referencing information | |
154 | ;; from all parts of the document, and across document borders | |
155 | ;; (`xr.sty'). | |
156 | ;; | |
157 | ;; 7. Document Parsing | |
f9ad2e24 CD |
158 | ;; RefTeX needs to parse the document in order to find labels and |
159 | ;; other information. It does it automatically once and updates its | |
1c25ed90 CD |
160 | ;; list internally when `reftex-label' and `reftex-index' are used. |
161 | ;; To enforce reparsing, call any of the commands described above | |
162 | ;; with a raw `C-u' prefix, or press the `r' key in the label | |
163 | ;; selection buffer, the table of contents buffer, or the index | |
164 | ;; buffer. | |
165 | ;; | |
166 | ;; 8. AUCTeX | |
167 | ;; If your major LaTeX mode is AUCTeX, RefTeX can cooperate with it | |
168 | ;; (see variable `reftex-plug-into-AUCTeX'). AUCTeX contains style | |
169 | ;; files which trigger appropriate settings in RefTeX, so that for | |
170 | ;; many of the popular LaTeX packages no additional customizations | |
171 | ;; will be necessary. | |
172 | ;; | |
173 | ;; 9. Useful Settings | |
174 | ;; To make RefTeX faster for large documents, try these: | |
f9ad2e24 CD |
175 | ;; (setq reftex-enable-partial-scans t) |
176 | ;; (setq reftex-save-parse-info t) | |
177 | ;; (setq reftex-use-multiple-selection-buffers t) | |
1c25ed90 CD |
178 | ;; |
179 | ;; To integrate with AUCTeX, use | |
f9ad2e24 | 180 | ;; (setq reftex-plug-into-AUCTeX t) |
1c25ed90 CD |
181 | ;; |
182 | ;; To make your own LaTeX macro definitions known to RefTeX, | |
183 | ;; customize the variables | |
184 | ;; `reftex-label-alist' (for label macros/environments) | |
185 | ;; `reftex-section-levels' (for sectioning commands) | |
186 | ;; `reftex-cite-format' (for `\cite'-like macros) | |
187 | ;; `reftex-index-macros' (for `\index'-like macros) | |
188 | ;; `reftex-index-default-macro' (to set the default macro) | |
189 | ;; If you have a large number of macros defined, you may want to write | |
190 | ;; an AUCTeX style file to support them with both AUCTeX and RefTeX. | |
191 | ;; | |
192 | ;; 10. Where Next? | |
193 | ;; Go ahead and use RefTeX. Use its menus until you have picked up | |
194 | ;; the key bindings. For an overview of what you can do in each of | |
195 | ;; the different special buffers, press `?'. Read the manual if you | |
196 | ;; get stuck. The first part of the manual explains in a tutorial | |
197 | ;; way how to use and customize RefTeX. The second part is a command | |
198 | ;; and variable reference. | |
