| 27 | ;;; Commentary: |
| 28 | ;; |
| 29 | ;; RefTeX is a minor mode with distinct support for \ref, \label, \cite, |
| 30 | ;; and \index commands in (multi-file) LaTeX documents. |
| 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. |
| 35 | ;; - The index preview buffer helps to check and edit index entries. |
| 36 | ;; |
| 37 | ;; |
| 38 | ;; INSTALLATION |
| 39 | ;; ------------ |
| 40 | ;; |
| 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. |
| 46 | ;; |
| 47 | ;; To turn RefTeX Mode on and off in a buffer, use `M-x reftex-mode'. |
| 48 | ;; |
| 49 | ;; To turn on RefTeX Mode for all LaTeX files, add the following lines |
| 50 | ;; to your .emacs file: |
| 51 | ;; |
| 52 | ;; (add-hook 'LaTeX-mode-hook 'turn-on-reftex) ; AUCTeX LaTeX mode |
| 53 | ;; (add-hook 'latex-mode-hook 'turn-on-reftex) ; Emacs latex mode |
| 54 | ;; |
| 55 | ;; |
| 56 | ;; DOCUMENTATION |
| 57 | ;; ------------- |
| 58 | ;; |
| 59 | ;; See below for a short summary of how to use RefTeX. |
| 60 | ;; |
| 61 | ;; There is an extensive texinfo document describing RefTeX in detail. |
| 62 | ;; One way to view this documentation is `M-x reftex-info RET'. |
| 63 | ;; |
| 64 | ;; The documentation in various formats is also available at |
| 65 | ;; |
| 66 | ;; http://www.strw.leidenuniv.nl/~dominik/Tools/ |

| 69 | ;; |
| 70 | ;; RefTeX in a Nutshell |
| 71 | ;; ==================== |
| 72 | ;; |
| 73 | ;; 1. Table of Contents |
| 74 | ;; Typing `C-c =' (`reftex-toc') will show a table of contents of the |
| 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. |
| 78 | ;; |
| 79 | ;; 2. Labels and References |
| 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 | ;; |
| 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 |
| 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 |
| 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 |
| 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 |
| 158 | ;; RefTeX needs to parse the document in order to find labels and |
| 159 | ;; other information. It does it automatically once and updates its |
| 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: |
| 175 | ;; (setq reftex-enable-partial-scans t) |
| 176 | ;; (setq reftex-save-parse-info t) |
| 177 | ;; (setq reftex-use-multiple-selection-buffers t) |
| 178 | ;; |
| 179 | ;; To integrate with AUCTeX, use |
| 180 | ;; (setq reftex-plug-into-AUCTeX t) |
| 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. |
