71 | ;; Introduction |
72 | ;; ************ | |
3666daf6 | 73 | ;; |
7c4d13cc CD |
74 | ;; RefTeX is a specialized package for support of labels, references, |
75 | ;; citations, and the index in LaTeX. RefTeX wraps itself round 4 LaTeX | |
76 | ;; macros: `\label', `\ref', `\cite', and `\index'. Using these macros | |
77 | ;; usually requires looking up different parts of the document and | |
78 | ;; searching through BibTeX database files. RefTeX automates these | |
79 | ;; time-consuming tasks almost entirely. It also provides functions to | |
80 | ;; display the structure of a document and to move around in this | |
81 | ;; structure quickly. | |
3666daf6 | 82 | ;; |
7c4d13cc CD |
83 | ;; *Note Imprint::, for information about who to contact for help, bug |
84 | ;; reports or suggestions. | |

7c4d13cc CD |
86 | ;; Environment |
87 | ;; =========== | |
3666daf6 | 88 | ;; |
7c4d13cc CD |
89 | ;; RefTeX needs to access all files which are part of a multifile |
90 | ;; document, and the BibTeX database files requested by the | |
91 | ;; `\bibliography' command. To find these files, RefTeX will require a | |
92 | ;; search path, i.e. a list of directories to check. Normally this list | |
93 | ;; is stored in the environment variables `TEXINPUTS' and `BIBINPUTS' | |
94 | ;; which are also used by RefTeX. However, on some systems these | |
95 | ;; variables do not contain the full search path. If RefTeX does not work | |
96 | ;; for you because it cannot find some files, read *Note Finding Files::. | |
3666daf6 | 97 | ;; |
7c4d13cc CD |
98 | ;; Entering RefTeX Mode |
99 | ;; ==================== | |
3666daf6 | 100 | ;; |
7c4d13cc CD |
101 | ;; To turn RefTeX Mode on and off in a particular buffer, use `M-x |
102 | ;; reftex-mode'. To turn on RefTeX Mode for all LaTeX files, add the | |
103 | ;; following lines to your `.emacs' file: | |
3666daf6 | 104 | ;; |
7c4d13cc CD |
105 | ;; (add-hook 'LaTeX-mode-hook 'turn-on-reftex) ; with AUCTeX LaTeX mode |
106 | ;; (add-hook 'latex-mode-hook 'turn-on-reftex) ; with Emacs latex mode | |
3666daf6 | 107 | ;; |

108 | ;; RefTeX in a Nutshell |
109 | ;; ==================== | |
3666daf6 | 110 | ;; |
f9ad2e24 CD |
111 | ;; 1. Table of Contents |
112 | ;; Typing `C-c =' (`reftex-toc') will show a table of contents of the | |
1c25ed90 CD |
113 | ;; document. This buffer can display sections, labels and index |
114 | ;; entries defined in the document. From the buffer, you can jump | |
115 | ;; quickly to every part of your document. Press `?' to get help. | |
3666daf6 | 116 | ;; |
f9ad2e24 | 117 | ;; 2. Labels and References |
1c25ed90 CD |
118 | ;; RefTeX helps to create unique labels and to find the correct key |
119 | ;; for references quickly. It distinguishes labels for different | |
120 | ;; environments, knows about all standard environments (and many | |
121 | ;; others), and can be configured to recognize any additional labeled | |
122 | ;; environments you have defined yourself (variable | |
123 | ;; `reftex-label-alist'). | |
3666daf6 | 124 | ;; |
1c25ed90 CD |
125 | ;; * Creating Labels |
126 | ;; Type `C-c (' (`reftex-label') to insert a label at point. | |
127 | ;; RefTeX will either | |
128 | ;; - derive a label from context (default for section labels) | |
129 | ;; - prompt for a label string (default for figures and | |
130 | ;; tables) or | |
131 | ;; - insert a simple label made of a prefix and a number (all | |
132 | ;; other environments) | |
3666daf6 | 133 | ;; |
1c25ed90 CD |
134 | ;; Which labels are created how is configurable with the variable |
135 | ;; `reftex-insert-label-flags'. | |
3666daf6 | 136 | ;; |
1c25ed90 CD |
137 | ;; * Referencing Labels |
138 | ;; To make a reference, type `C-c )' (`reftex-reference'). This | |
139 | ;; shows an outline of the document with all labels of a certain | |
140 | ;; type (figure, equation,...) and some label context. | |
141 | ;; Selecting a label inserts a `\ref{LABEL}' macro into the | |
142 | ;; original buffer. | |
3666daf6 | 143 | ;; |
f9ad2e24 CD |
144 | ;; 3. Citations |
145 | ;; Typing `C-c [' (`reftex-citation') will let you specify a regular | |
146 | ;; expression to search in current BibTeX database files (as | |
147 | ;; specified in the `\bibliography' command) and pull out a list of | |
7c4d13cc | 148 | ;; matches for you to choose from. The list is _formatted_ and |
f9ad2e24 | 149 | ;; sorted. The selected article is referenced as `\cite{KEY}' (see |
1c25ed90 CD |
150 | ;; the variable `reftex-cite-format' if you want to insert different |
151 | ;; macros). | |
3666daf6 | 152 | ;; |
1c25ed90 CD |
153 | ;; 4. Index Support |
154 | ;; RefTeX helps to enter index entries. It also compiles all entries | |
155 | ;; into an alphabetically sorted `*Index*' buffer which you can use | |
156 | ;; to check and edit the entries. RefTeX knows about the standard | |
157 | ;; index macros and can be configured to recognize any additional | |
158 | ;; macros you have defined (`reftex-index-macros'). Multiple indices | |
159 | ;; are supported. | |
3666daf6 | 160 | ;; |
1c25ed90 | 161 | ;; * Creating Index Entries |
7c4d13cc CD |
162 | ;; To index the current selection or the word at point, type |
163 | ;; `C-c /' (`reftex-index-selection-or-word'). The default macro | |
164 | ;; `reftex-index-default-macro' will be used. For a more | |
165 | ;; complex entry type `C-c <' (`reftex-index'), select any of | |
166 | ;; the index macros and enter the arguments with completion. | |
3666daf6 | 167 | ;; |
7c4d13cc CD |
168 | ;; * The Index Phrases File (Delayed Indexing) |
169 | ;; Type `C-c \' (`reftex-index-phrase-selection-or-word') to add | |
170 | ;; the current word or selection to a special _index phrase | |
171 | ;; file_. RefTeX can later search the document for occurrences | |
172 | ;; of these phrases and let you interactively index the matches. | |
3666daf6 | 173 | ;; |
7c4d13cc | 174 | ;; * Displaying and Editing the Index |
1c25ed90 CD |
175 | ;; To display the compiled index in a special buffer, type `C-c |
176 | ;; >' (`reftex-display-index'). From that buffer you can check | |
7c4d13cc | 177 | ;; and edit all entries. |
3666daf6 | 178 | ;; |
1c25ed90 | 179 | ;; 5. Viewing Cross-References |
921759ee CD |
180 | ;; When point is on the KEY argument of a cross-referencing macro |
181 | ;; (`\label', `\ref', `\cite', `\bibitem', `\index', and variations) | |
182 | ;; or inside a BibTeX database entry, you can press `C-c &' | |
183 | ;; (`reftex-view-crossref') to display corresponding locations in the | |
184 | ;; document and associated BibTeX database files. | |
185 | ;; When the enclosing macro is `\cite' or `\ref' and no other message | |
186 | ;; occupies the echo area, information about the citation or label | |
1c25ed90 | 187 | ;; will automatically be displayed in the echo area. |
3666daf6 | 188 | ;; |
1c25ed90 CD |
189 | ;; 6. Multifile Documents |
190 | ;; Multifile Documents are fully supported. The included files must | |
191 | ;; have a file variable `TeX-master' or `tex-main-file' pointing to | |
192 | ;; the master file. RefTeX provides cross-referencing information | |
193 | ;; from all parts of the document, and across document borders | |
194 | ;; (`xr.sty'). | |
3666daf6 | 195 | ;; |
1c25ed90 | 196 | ;; 7. Document Parsing |
f9ad2e24 CD |
197 | ;; RefTeX needs to parse the document in order to find labels and |
198 | ;; other information. It does it automatically once and updates its | |
1c25ed90 CD |
199 | ;; list internally when `reftex-label' and `reftex-index' are used. |
200 | ;; To enforce reparsing, call any of the commands described above | |
201 | ;; with a raw `C-u' prefix, or press the `r' key in the label | |
202 | ;; selection buffer, the table of contents buffer, or the index | |
203 | ;; buffer. | |
3666daf6 | 204 | ;; |
1c25ed90 CD |
205 | ;; 8. AUCTeX |
206 | ;; If your major LaTeX mode is AUCTeX, RefTeX can cooperate with it | |
207 | ;; (see variable `reftex-plug-into-AUCTeX'). AUCTeX contains style | |
208 | ;; files which trigger appropriate settings in RefTeX, so that for | |
209 | ;; many of the popular LaTeX packages no additional customizations | |
210 | ;; will be necessary. | |
3666daf6 | 211 | ;; |
1c25ed90 CD |
212 | ;; 9. Useful Settings |
213 | ;; To make RefTeX faster for large documents, try these: | |
f9ad2e24 CD |
214 | ;; (setq reftex-enable-partial-scans t) |
215 | ;; (setq reftex-save-parse-info t) | |
216 | ;; (setq reftex-use-multiple-selection-buffers t) | |
3666daf6 | 217 | ;; |
1c25ed90 | 218 | ;; To integrate with AUCTeX, use |
f9ad2e24 | 219 | ;; (setq reftex-plug-into-AUCTeX t) |
3666daf6 | 220 | ;; |
1c25ed90 CD |
221 | ;; To make your own LaTeX macro definitions known to RefTeX, |
222 | ;; customize the variables | |
223 | ;; `reftex-label-alist' (for label macros/environments) | |
224 | ;; `reftex-section-levels' (for sectioning commands) | |
225 | ;; `reftex-cite-format' (for `\cite'-like macros) | |
226 | ;; `reftex-index-macros' (for `\index'-like macros) | |
227 | ;; `reftex-index-default-macro' (to set the default macro) | |
228 | ;; If you have a large number of macros defined, you may want to write | |
229 | ;; an AUCTeX style file to support them with both AUCTeX and RefTeX. | |
3666daf6 | 230 | ;; |
1c25ed90 CD |
231 | ;; 10. Where Next? |
232 | ;; Go ahead and use RefTeX. Use its menus until you have picked up | |
233 | ;; the key bindings. For an overview of what you can do in each of | |
234 | ;; the different special buffers, press `?'. Read the manual if you | |
7c4d13cc CD |
235 | ;; get stuck, of if you are curious what else might be available. |
236 | ;; The first part of the manual explains in a tutorial way how to use | |
237 | ;; and customize RefTeX. The second part is a command and variable | |
238 | ;; reference. | |
