203 | ||
204 | @b{Ref@TeX{}} is a specialized package for support of labels, | |
205 | references, citations, and the index in LaTeX. @b{Ref@TeX{}} wraps | |
206 | itself round 4 LaTeX macros: @code{\label}, @code{\ref}, @code{\cite}, | |
207 | and @code{\index}. Using these macros usually requires looking up | |
208 | different parts of the document and searching through BibTeX database | |
209 | files. @b{Ref@TeX{}} automates these time--consuming tasks almost | |
210 | entirely. It also provides functions to display the structure of a | |
211 | document and to move around in this structure quickly. | |
212 | ||

229 | @section Installation | |
230 | @cindex Installation | |
231 | ||
232 | @b{Ref@TeX{}} is bundled and pre--installed with Emacs since version | |
233 | 20.2. It was also bundled and pre--installed with XEmacs 19.16--20.x. | |
234 | XEmacs 21.x users want to install the corresponding plug-in package | |
235 | which is available from the @value{XEMACSFTP}. See the XEmacs 21.x | |
236 | documentation on package installation for details. | |
237 | ||
238 | Users of earlier Emacs distributions (including Emacs 19) can get a copy | |
239 | of the @b{Ref@TeX{}} distribution from the maintainers web-page. | |
240 | @xref{Imprint}, for more information. | |

246 | @cindex @code{TEXINPUTS}, environment variable | |
247 | @cindex @code{BIBINPUTS}, environment variable | |
248 | ||
249 | @b{Ref@TeX{}} needs to access all files which are part of a multifile | |
250 | document, and the BibTeX database files requested by the | |
251 | @code{\bibliography} command. To find these files, @b{Ref@TeX{}} will | |
252 | require a search path, i.e. a list of directories to check. Normally | |
253 | this list is stored in the environment variables @code{TEXINPUTS} and | |
254 | @code{BIBINPUTS} which are also used by @b{Ref@TeX{}}. However, on some | |
255 | systems these variables do not contain the full search path. If | |
256 | @b{Ref@TeX{}} does not work for you because it cannot find some files, | |
257 | read @ref{Finding Files}. | |

282 | @enumerate | |
283 | @item | |
284 | @b{Table of Contents}@* Typing @kbd{C-c =} (@code{reftex-toc}) will show | |
285 | a table of contents of the document. This buffer can display sections, | |
286 | labels and index entries defined in the document. From the buffer, you | |
287 | can jump quickly to every part of your document. Press @kbd{?} to get | |
288 | help. | |
289 | ||
290 | @item | |
291 | @b{Labels and References}@* @b{Ref@TeX{}} helps to create unique labels | |
292 | and to find the correct key for references quickly. It distinguishes | |
293 | labels for different environments, knows about all standard | |
294 | environments (and many others), and can be configured to recognize any | |
295 | additional labeled environments you have defined yourself (variable | |
296 | @code{reftex-label-alist}). | |
297 | ||
298 | @itemize @bullet | |
299 | @item | |
300 | @b{Creating Labels}@* | |
301 | Type @kbd{C-c (} (@code{reftex-label}) to insert a label at point. | |
302 | @b{Ref@TeX{}} will either | |
303 | @itemize @minus | |
304 | @item | |
305 | derive a label from context (default for section labels) | |
306 | @item | |
307 | prompt for a label string (default for figures and tables) or | |
308 | @item | |
309 | insert a simple label made of a prefix and a number (all other | |
310 | environments) | |
311 | @end itemize | |
312 | @noindent | |
313 | Which labels are created how is configurable with the variable | |
314 | @code{reftex-insert-label-flags}. | |
315 | ||
316 | @item | |
317 | @b{Referencing Labels}@* To make a reference, type @kbd{C-c )} | |
318 | (@code{reftex-reference}). This shows an outline of the document with | |
319 | all labels of a certain type (figure, equation,...) and some label | |
320 | context. Selecting a label inserts a @code{\ref@{@var{label}@}} macro | |
321 | into the original buffer. | |
322 | @end itemize | |
323 | ||
324 | @item | |
325 | @b{Citations}@* | |
326 | Typing @kbd{C-c [} (@code{reftex-citation}) will let you specify a | |
327 | regular expression to search in current BibTeX database files (as | |
328 | specified in the @code{\bibliography} command) and pull out a list of | |
329 | matches for you to choose from. The list is @emph{formatted} and | |
330 | sorted. The selected article is referenced as @samp{\cite@{@var{key}@}} | |
331 | (see the variable @code{reftex-cite-format} if you want to insert | |
332 | different macros). | |
333 | ||
334 | @item | |
335 | @b{Index Support}@* | |
336 | @b{Ref@TeX{}} helps to enter index entries. It also compiles all | |
337 | entries into an alphabetically sorted @file{*Index*} buffer which you | |
338 | can use to check and edit the entries. @b{Ref@TeX{}} knows about the | |
339 | standard index macros and can be configured to recognize any additional | |
340 | macros you have defined (@code{reftex-index-macros}). Multiple indices | |
341 | are supported. | |
342 | ||
343 | @itemize @bullet | |
344 | @item | |
345 | @b{Creating Index Entries}@* | |
346 | To index the current selection or the word at point, type @kbd{C-c /} | |
347 | (@code{reftex-index-selection-or-word}). The default macro | |
348 | @code{reftex-index-default-macro} will be used. For a more complex entry | |
349 | type @kbd{C-c <} (@code{reftex-index}), select any of the index macros | |
350 | and enter the arguments with completion. | |
351 | ||
352 | @item | |
353 | @b{The Index Phrases File (Delayed Indexing)}@* | |
354 | Type @kbd{C-c \} (@code{reftex-index-phrase-selection-or-word}) to add | |
355 | the current word or selection to a special @emph{index phrase file}. | |
356 | @b{Ref@TeX{}} can later search the document for occurrences of these | |
357 | phrases and let you interactively index the matches. | |
358 | ||
359 | @item | |
360 | @b{Displaying and Editing the Index}@* | |
361 | To display the compiled index in a special buffer, type @kbd{C-c >} | |
362 | (@code{reftex-display-index}). From that buffer you can check and edit | |
363 | all entries. | |
364 | @end itemize | |
365 | ||
366 | @page | |
367 | @item @b{Viewing Cross-References}@* | |
368 | When point is on the @var{key} argument of a cross--referencing macro | |
369 | (@code{\label}, @code{\ref}, @code{\cite}, @code{\bibitem}, | |
370 | @code{\index}, and variations) or inside a BibTeX database entry, you | |
371 | can press @kbd{C-c &} (@code{reftex-view-crossref}) to display | |
372 | corresponding locations in the document and associated BibTeX database | |
373 | files. @* | |
374 | When the enclosing macro is @code{\cite} or @code{\ref} and no other | |
375 | message occupies the echo area, information about the citation or label | |
376 | will automatically be displayed in the echo area. | |
377 | ||
378 | @item | |
379 | @b{Multifile Documents}@* | |
380 | Multifile Documents are fully supported. The included files must have a | |
381 | file variable @code{TeX-master} or @code{tex-main-file} pointing to the | |
382 | master file. @b{Ref@TeX{}} provides cross-referencing information from | |
383 | all parts of the document, and across document borders | |
384 | (@file{xr.sty}). | |
385 | ||
386 | @item | |
387 | @b{Document Parsing}@* @b{Ref@TeX{}} needs to parse the document in | |
388 | order to find labels and other information. It does it automatically | |
389 | once and updates its list internally when @code{reftex-label} and | |
390 | @code{reftex-index} are used. To enforce reparsing, call any of the | |
391 | commands described above with a raw @kbd{C-u} prefix, or press the | |
392 | @kbd{r} key in the label selection buffer, the table of contents | |
393 | buffer, or the index buffer. | |
394 | ||
395 | @item | |
396 | @b{AUCTeX} @* If your major LaTeX mode is AUCTeX, @b{Ref@TeX{}} can | |
397 | cooperate with it (see variable @code{reftex-plug-into-AUCTeX}). AUCTeX | |
398 | contains style files which trigger appropriate settings in | |
399 | @b{Ref@TeX{}}, so that for many of the popular LaTeX packages no | |
400 | additional customizations will be necessary. | |
401 | ||
402 | @item | |
403 | @b{Useful Settings}@* | |
404 | To integrate RefTeX with AUCTeX, use | |
405 | @lisp | |
406 | (setq reftex-plug-into-AUCTeX t) | |
407 | @end lisp | |
408 | ||
409 | To make your own LaTeX macro definitions known to @b{Ref@TeX{}}, | |
410 | customize the variables | |
411 | @example | |
412 | @code{reftex-label-alist} @r{(for label macros/environments)} | |
413 | @code{reftex-section-levels} @r{(for sectioning commands)} | |
414 | @code{reftex-cite-format} @r{(for @code{\cite}-like macros)} | |
415 | @code{reftex-index-macros} @r{(for @code{\index}-like macros)} | |
416 | @code{reftex-index-default-macro} @r{(to set the default macro)} | |
417 | @end example | |
418 | If you have a large number of macros defined, you may want to write | |
419 | an AUCTeX style file to support them with both AUCTeX and | |
420 | @b{Ref@TeX{}}. | |
421 | ||
422 | @item @b{Where Next?}@* Go ahead and use @b{Ref@TeX{}}. Use its menus | |
423 | until you have picked up the key bindings. For an overview of what you | |
424 | can do in each of the different special buffers, press @kbd{?}. Read | |
425 | the manual if you get stuck, of if you are curious what else might be | |
426 | available. The first part of the manual explains in | |
427 | a tutorial way how to use and customize @b{Ref@TeX{}}. The second | |
428 | part is a command and variable reference. | |

446 | document, simple key strokes will display the corresponding part in | |
447 | another window, jump to that location, or perform other actions. | |
448 | ||
449 | @kindex ? | |
450 | Here is a list of special commands in the @file{*toc*} buffer. A | |
451 | summary of this information is always available by pressing | |
452 | @kbd{?}. | |

454 | @table @kbd | |
455 | ||
456 | @tablesubheading{General} | |
457 | @item ? | |
458 | Display a summary of commands. | |
459 | ||
460 | @item 0-9, - | |
461 | Prefix argument. | |
462 | ||
463 | @tablesubheading{Moving around} | |
464 | @item n | |
465 | Goto next entry in the table of context. | |
466 | ||
467 | @item p | |
468 | Goto previous entry in the table of context. | |
469 | ||
470 | @item C-c C-n | |
471 | Goto next section heading. Useful when many labels and index entries | |
472 | separate section headings. | |
473 | ||
474 | @item C-c C-p | |
475 | Goto previous section heading. | |
476 | ||
477 | @item N z | |
478 | Jump to section N, using the prefix arg. For example, @kbd{3 z} jumps | |
479 | to section 3. | |
480 | ||
481 | @tablesubheading{Access to document locations} | |
482 | @item @key{SPC} | |
483 | Show the corresponding location in another window. This command does | |
484 | @emph{not} select that other window. | |
485 | ||
486 | @item @key{TAB} | |
487 | Goto the location in another window. | |
488 | ||
489 | @item @key{RET} | |
490 | Go to the location and hide the @file{*toc*} buffer. This will restore | |
491 | the window configuration before @code{reftex-toc} (@kbd{C-c =}) was | |
492 | called. | |
493 | ||
494 | @item mouse-2 | |
495 | @vindex reftex-highlight-selection | |
496 | Clicking with mouse button 2 on a line has the same effect as @key{RET}. | |
497 | See also variable @code{reftex-highlight-selection}, @ref{Options | |
498 | (Fontification)}. | |
499 | ||
500 | @item f | |
501 | @vindex reftex-toc-follow-mode | |
502 | @vindex reftex-revisit-to-follow | |
503 | Toggle follow mode. When follow mode is active, the other window will | |
504 | always show the location corresponding to the line at point in the | |
505 | @file{*toc*} buffer. This is similar to pressing @key{SPC} after each | |
506 | cursor motion. The default for this flag can be set with the variable | |
507 | @code{reftex-toc-follow-mode}. Note that only context in files already | |
508 | visited is shown. @b{Ref@TeX{}} will not visit a file just for follow | |
509 | mode. See, however, the variable | |
510 | @code{reftex-revisit-to-follow}. | |
511 | ||
512 | @item . | |
513 | Show calling point in another window. This is the point from where | |
514 | @code{reftex-toc} was last called. | |
515 | ||
516 | @page | |
517 | @tablesubheading{Promotion and Demotion} | |
518 | ||
519 | @item < | |
520 | Promote the current section. This will convert @code{\section} to | |
521 | @code{\chapter}, @code{\subsection} to @code{\section} etc. If there is | |
522 | an active region, all sections in the region will be promoted, including | |
523 | the one at point. To avoid mistakes, @b{Ref@TeX{}} requires a fresh | |
524 | document scan before executing this command - if necessary, it will | |
525 | automatically do this scan and ask the user to repeat the promotion | |
526 | command. | |
527 | ||
528 | @item > | |
529 | Demote the current section. This is the opposite of promotion. It will | |
530 | convert @code{\chapter} to @code{\section} etc. If there is an active | |
531 | region, all sections in the region will be demoted, including the one at | |
532 | point. | |
533 | ||
534 | @item M-% | |
535 | Rename the label at point. While generally not recommended, this can be | |
536 | useful when a package like @file{fancyref} is used where the label | |
537 | prefix determines the wording of a reference. After a | |
538 | promotion/demotion it may be necessary to change a few labels from | |
539 | @samp{sec:xyz} to @samp{cha:xyz} or vice versa. This command can be | |
540 | used to do this - it launches a query replace to rename the definition | |
541 | and all references of a label. | |
542 | ||
543 | @tablesubheading{Exiting} | |
544 | @item q | |
545 | Hide the @file{*toc*} buffer, return to the position where | |
546 | @code{reftex-toc} was last called. | |
547 | ||
548 | @item k | |
549 | Kill the @file{*toc*} buffer, return to the position where | |
550 | @code{reftex-toc} was last called. | |
551 | ||
552 | @item C-c > | |
553 | Switch to the @file{*Index*} buffer of this document. With prefix | |
554 | @samp{2}, restrict the index to the section at point in the @file{*toc*} | |
555 | buffer. | |

557 | @tablesubheading{Controlling what gets displayed} | |
558 | ||
559 | @item t | |
560 | @vindex reftex-toc-max-level | |
561 | Change the maximum level of toc entries displayed in the @file{*toc*} | |
562 | buffer. Without prefix arg, all levels will be included. With prefix | |
563 | arg (e.g @kbd{3 t}), ignore all toc entries with level greater than | |
564 | @var{arg} (3 in this case). Chapters are level 1, sections are level 2. | |
565 | The mode line @samp{T<>} indicator shows the current value. The default | |
566 | depth can be configured with the variable | |
567 | @code{reftex-toc-max-level}. | |
568 | ||
569 | @item F | |
570 | @vindex reftex-toc-include-file-boundaries | |
571 | Toggle the display of the file borders of a multifile document in the | |
572 | @file{*toc*} buffer. The default for this flag can be set with the | |
573 | variable @code{reftex-toc-include-file-boundaries}. | |
574 | ||
575 | @item l | |
576 | @vindex reftex-toc-include-labels | |
577 | Toggle the display of labels in the @file{*toc*} buffer. The default | |
578 | for this flag can be set with the variable | |
579 | @code{reftex-toc-include-labels}. When called with a prefix argument, | |
580 | @b{Ref@TeX{}} will prompt for a label type and include only labels of | |
581 | the selected type in the @file{*toc*} buffer. The mode line @samp{L<>} | |
582 | indicator shows which labels are included. | |
583 | ||
584 | @item i | |
585 | @vindex reftex-toc-include-index-entries | |
586 | Toggle the display of index entries in the @file{*toc*} buffer. The | |
587 | default for this flag can be set with the variable | |
588 | @code{reftex-toc-include-index-entries}. When called with a prefix | |
589 | argument, @b{Ref@TeX{}} will prompt for a specific index and include | |
590 | only entries in the selected index in the @file{*toc*} buffer. The mode | |
591 | line @samp{I<>} indicator shows which index is used. | |
592 | ||
593 | @item c | |
594 | @vindex reftex-toc-include-context | |
595 | Toggle the display of label and index context in the @file{*toc*} | |
596 | buffer. The default for this flag can be set with the variable | |
597 | @code{reftex-toc-include-context}. | |
598 | ||
599 | @tablesubheading{Updating the buffer} | |
600 | ||
601 | @item g | |
602 | Rebuild the @file{*toc*} buffer. This does @emph{not} rescan the | |
603 | document. | |
604 | ||
605 | @item r | |
606 | @vindex reftex-enable-partial-scans | |
607 | Reparse the LaTeX document and rebuild the @file{*toc*} buffer. When | |
608 | @code{reftex-enable-partial-scans} is non-@code{nil}, rescan only the file this | |
609 | location is defined in, not the entire document. | |
610 | ||
611 | @item C-u r | |
612 | Reparse the @emph{entire} LaTeX document and rebuild the @file{*toc*} | |
613 | buffer. | |
614 | ||
615 | @item x | |
616 | Switch to the @file{*toc*} buffer of an external document. When the | |
617 | current document is using the @code{xr} package (@pxref{xr (LaTeX | |
618 | package)}), @b{Ref@TeX{}} will switch to one of the external | |
619 | documents. | |
620 | ||
621 | ||
622 | @tablesubheading{Automatic recentering} | |
623 | ||
624 | @item d | |
625 | Toggle the display of a dedicated frame displaying just the @file{*toc*} | |
626 | buffer. Follow mode and visiting locations will not work that frame, | |
627 | but automatic recentering will make this frame always show your current | |
628 | editing location in the document (see below). | |
629 | ||
630 | @item a | |
631 | Toggle the automatic recentering of the @file{*toc*} buffer. When this | |
632 | option is on, moving around in the document will cause the @file{*toc*} | |
633 | to always highlight the current section. By default, this option is | |
634 | active while the dedicated @file{*TOC*} frame exists. See also the | |
635 | variable @code{reftex-auto-recenter-toc}. | |
636 | ||
637 | @end table | |

639 | @vindex reftex-toc-map | |
640 | In order to define additional commands for the @file{*toc*} buffer, the | |

646 | @cindex @file{*toc*} buffer, recentering | |
647 | @cindex Table of contents buffer, recentering | |
648 | @kindex C-c - | |
649 | If you call @code{reftex-toc} while the @file{*toc*} buffer already | |
650 | exists, the cursor will immediately jump to the right place, i.e. the | |
651 | section from which @code{reftex-toc} was called will be highlighted. | |
652 | The command @kbd{C-c -} (@code{reftex-toc-recenter}) will only redisplay | |
653 | the @file{*toc*} buffer and highlight the correct line without actually | |
654 | selecting the @file{*toc*} window. This can be useful to quickly find | |
655 | out where in the document you currently are. You can also automate this | |
656 | by asking RefTeX to keep track of your current editing position in the | |
657 | TOC. The TOC window will then be updated whenever you stop typing for | |
658 | more than @code{reftex-idle-time} seconds. By default this works only | |
659 | with the dedicated @file{*TOC*} frame. But you can also force automatic | |
660 | recentering of the TOC window on the current frame with | |
661 | @lisp | |
662 | (setq reftex-auto-recenter-toc t) | |

687 | ||
688 | LaTeX provides a powerful mechanism to deal with cross--references in a | |
689 | document. When writing a document, any part of it can be marked with a | |
690 | label, like @samp{\label@{mark@}}. LaTeX records the current value of a | |
691 | certain counter when a label is defined. Later references to this label | |
692 | (like @samp{\ref@{mark@}}) will produce the recorded value of the | |
693 | counter. | |
694 | ||
695 | Labels can be used to mark sections, figures, tables, equations, | |
696 | footnotes, items in enumerate lists etc. LaTeX is context sensitive in | |
697 | doing this: A label defined in a figure environment automatically | |
698 | records the figure counter, not the section counter. | |
699 | ||
700 | Several different environments can share a common counter and therefore | |
701 | a common label category. E.g. labels in both @code{equation} and | |
702 | @code{eqnarray} environments record the value of the same counter - the | |
703 | equation counter. | |

723 | ||
724 | In order to create a label in a LaTeX document, press @kbd{C-c (} | |
725 | (@code{reftex-label}). Just like LaTeX, @b{Ref@TeX{}} is context sensitive | |
726 | and will figure out the environment it currently is in and adapt the | |
727 | label to that environment. A label usually consists of a short prefix | |
728 | indicating the type of the label and a unique mark. @b{Ref@TeX{}} has | |
729 | 3 different modes to create this mark. | |
730 | ||
731 | @enumerate | |
732 | @item | |
733 | @vindex reftex-translate-to-ascii-function | |
734 | @vindex reftex-derive-label-parameters | |
735 | @vindex reftex-label-illegal-re | |
736 | @vindex reftex-abbrev-parameters | |
737 | A label can be derived from context. This means, @b{Ref@TeX{}} takes | |
738 | the context of the label definition and constructs a label from | |
739 | that@footnote{Note that the context may contain constructs which are | |
740 | invalid in labels. @b{Ref@TeX{}} will therefore strip the accent from | |
741 | accented Latin-1 characters and remove everything else which is not | |
742 | valid in labels. This mechanism is safe, but may not be satisfactory | |
743 | for non-western languages. Check the following variables if you need to | |
744 | change things: @code{reftex-translate-to-ascii-function}, | |
745 | @code{reftex-derive-label-parameters}, @code{reftex-label-illegal-re}, | |
746 | @code{reftex-abbrev-parameters}.}. This works best for section labels, | |
747 | where the section heading is used to construct a label. In fact, | |
748 | @b{Ref@TeX{}}'s default settings use this method only for section | |
749 | labels. You will be asked to confirm the derived label, or edit | |
750 | it. | |
751 | ||
752 | @item | |
753 | We may also use a simple unique number to identify a label. This is | |
754 | mostly useful for labels where it is difficult to come up with a very | |
755 | good descriptive name. @b{Ref@TeX{}}'s default settings use this method | |
756 | for equations, enumerate items and footnotes. The author of @b{Ref@TeX{}} | |
757 | tends to write documents with many equations and finds it impossible | |
758 | to come up with good names for each of them. These simple labels are | |
759 | inserted without query, and are therefore very fast. Good descriptive | |
760 | names are not really necessary as @b{Ref@TeX{}} will provide context to | |
761 | reference a label (@pxref{Referencing Labels}). | |
762 | ||
763 | @item | |
764 | The third method is to ask the user for a label. This is most | |
765 | useful for things which are easy to describe briefly and do not turn up | |
766 | too frequently in a document. @b{Ref@TeX{}} uses this for figures and | |
767 | tables. Of course, one can enter the label directly by typing the full | |
768 | @samp{\label@{mark@}}. The advantage of using @code{reftex-label} | |
769 | anyway is that @b{Ref@TeX{}} will know that a new label has been defined. | |
770 | It will then not be necessary to rescan the document in order to access | |
771 | this label later. | |
772 | @end enumerate | |
773 | ||
774 | @vindex reftex-insert-label-flags | |
775 | If you want to change the way certain labels are created, check out the | |
776 | variable @code{reftex-insert-label-flags} (@pxref{Options (Creating | |
777 | Labels)}). | |
778 | ||
779 | If you are using AUCTeX to write your LaTeX documents, you can | |
780 | set it up to delegate the creation of labels to | |
781 | @b{Ref@TeX{}}. @xref{AUCTeX}, for more information. | |

793 | @vindex reftex-trust-label-prefix | |
794 | @b{Ref@TeX{}} scans the document in order to find all labels. To make | |
795 | referencing labels easier, it assigns to each label a category, the | |
796 | @emph{label type} (for example section, table, figure, equation, etc.). | |
797 | In order to determine the label type, RefTeX parses around each label | |
798 | to see in what kind of environments it is located. You can speed up | |
799 | the parsing by using type-specific prefixes for labels and configuring | |
800 | the variable @code{reftex-trust-label-prefix}. | |
801 | ||
802 | Referencing Labels is really at the heart of @b{Ref@TeX{}}. Press @kbd{C-c | |
803 | )} in order to reference a label (reftex-reference). This will start a | |
804 | selection process and finally insert the complete @samp{\ref@{label@}} | |
805 | into the buffer. | |
806 | ||
807 | First, @b{Ref@TeX{}} will determine the label category which is required. | |
808 | Often that can be figured out from context. For example, if you | |
809 | write @samp{As shown in eq.} and the press @kbd{C-c )}, @b{Ref@TeX{}} knows | |
810 | that an equation label is going to be referenced. If it cannot figure | |
811 | out what label category is needed, it will query for one. | |
812 | ||
813 | You will then be presented with a label selection menu. This is a | |
814 | special buffer which contains an outline of the document along with all | |
815 | labels of the given label category. In addition, next to the label | |
816 | there will be one line of context of the label definition, which is some | |
817 | text in the buffer near the label definition. Usually this is | |
818 | sufficient to identify the label. If you are unsure about a certain | |
819 | label, pressing @key{SPC} will show the label definition point in | |
820 | another window. | |
821 | ||
822 | In order to reference a label, move to cursor to the correct label and | |
823 | press @key{RET}. You can also reference several labels with a single | |
824 | call to @code{reftex-reference} by marking entries with the @kbd{m} | |
825 | key (see below). | |
826 | ||
827 | @kindex ? | |
828 | Here is a list of special commands in the selection buffer. A summary | |

848 | ||
849 | @item b | |
850 | Jump back to the position where you last left the selection buffer. | |
851 | Normally this should get you back to the last referenced label. | |

872 | to pressing @key{SPC} after each cursor motion. Note that only context | |
873 | in files already visited is shown. @b{RefTeX} will not visit a file | |
874 | just for follow mode. See, however, the variable | |

1122 | @b{Ref@TeX{}} can be configured to recognize additional labeled | |

1124 | @code{reftex-label-alist} (@pxref{Options (Defining Label | |
1125 | Environments)}). If you are not familiar with Lisp, you can use the | |
1126 | @code{custom} library to configure this rather complex variable. To do | |
1127 | this, use | |

1155 | ||
1156 | Suppose you are using @code{\newtheorem} in LaTeX in order to define two | |
1157 | new environments, @code{theorem} and @code{axiom} | |
1158 | ||
1159 | @example | |
1160 | \newtheorem@{axiom@}@{Axiom@} | |
1161 | \newtheorem@{theorem@}@{Theorem@} | |
1162 | @end example | |
1163 | ||
1164 | @noindent | |
1165 | to be used like this: | |
1166 | ||
1167 | @example | |
1168 | \begin@{axiom@} | |
1169 | \label@{ax:first@} | |
1170 | .... | |
1171 | \end@{axiom@} | |
1172 | @end example | |
1173 | ||
1174 | So we need to tell @b{Ref@TeX{}} that @code{theorem} and @code{axiom} are new | |
1175 | labeled environments which define their own label categories. We can | |
1176 | either use Lisp to do this (e.g. in @file{.emacs}) or use the custom | |
1177 | library. With Lisp it would look like this | |
1178 | ||
1179 | @lisp | |
1180 | (setq reftex-label-alist | |
1181 | '(("axiom" ?a "ax:" "~\\ref@{%s@}" nil ("axiom" "ax.") -2) | |
1182 | ("theorem" ?h "thr:" "~\\ref@{%s@}" t ("theorem" "th.") -3))) | |
1183 | @end lisp | |
1184 | ||
1185 | The type indicator characters @code{?a} and @code{?h} are used for | |
1186 | prompts when @b{Ref@TeX{}} queries for a label type. @code{?h} | |
1187 | was chosen for @code{theorem} since @code{?t} is already taken by | |
1188 | @code{table}. Note that also @code{?s}, @code{?f}, @code{?e}, | |
1189 | @code{?i}, @code{?n} are already used for standard environments. | |
1190 | ||
1191 | @noindent | |
1192 | The labels for Axioms and Theorems will have the prefixes @samp{ax:} and | |
1193 | @samp{thr:}, respectively. @xref{AUCTeX}, for information on how | |
1194 | AUCTeX can use RefTeX to automatically create labels when a new environment | |
1195 | is inserted into a buffer. Additionally, the following needs to be | |
1196 | added to one's .emacs file before AUCTeX will automatically create | |
1197 | labels for the new environments. | |
1198 | ||
1199 | @lisp | |

1205 | @end lisp | |
1206 | ||
1207 | ||
1208 | @noindent | |
1209 | The @samp{~\ref@{%s@}} is a format string indicating how to insert | |
1210 | references to these labels. | |
1211 | ||
1212 | @noindent | |
1213 | The next item indicates how to grab context of the label definition. | |
1214 | @itemize @minus | |
1215 | @item | |
1216 | @code{t} means to get it from a default location (from the beginning of | |
1217 | a @code{\macro} or after the @code{\begin} statement). @code{t} is | |
1218 | @emph{not} a good choice for eqnarray and similar environments. | |
1219 | @item | |
1220 | @code{nil} means to use the text right after the label definition. | |
1221 | @item | |
1222 | For more complex ways of getting context, see the variable | |
1223 | @code{reftex-label-alist} (@ref{Options (Defining Label | |
1224 | Environments)}). | |
1225 | @end itemize | |
1226 | ||
1227 | The following list of strings is used to guess the correct label type | |
1228 | from the word before point when creating a reference. E.g. if you | |
1229 | write: @samp{As we have shown in Theorem} and then press @kbd{C-c )}, | |
1230 | @b{Ref@TeX{}} will know that you are looking for a theorem label and | |
1231 | restrict the menu to only these labels without even asking. | |
1232 | ||
1233 | The final item in each entry is the level at which the environment | |
1234 | should produce entries in the table of context buffer. If the number is | |
1235 | positive, the environment will produce numbered entries (like | |
1236 | @code{\section}), if it is negative the entries will be unnumbered (like | |
1237 | @code{\section*}). Use this only for environments which structure the | |
1238 | document similar to sectioning commands. For everything else, omit the | |
1239 | item. | |
1240 | ||
1241 | To do the same configuration with @code{customize}, you need to click on | |
1242 | the @code{[INS]} button twice to create two templates and fill them in | |
1243 | like this: | |

1299 | @end example | |
1300 | ||
1301 | We need to tell @b{Ref@TeX{}} that any label defined in the argument of the | |
1302 | @code{\quickeq} is an equation label. Here is how to do this with lisp: | |
1303 | ||
1304 | @lisp | |
1305 | (setq reftex-label-alist '(("\\quickeq@{@}" ?e nil nil 1 nil))) | |

1307 | ||
1308 | The first element in this list is now the macro with empty braces as an | |
1309 | @emph{image} of the macro arguments. @code{?e} indicates that this is | |
1310 | an equation label, the different @code{nil} elements indicate to use the | |
1311 | default values for equations. The @samp{1} as the fifth element | |
1312 | indicates that the context of the label definition should be the 1st | |
1313 | argument of the macro. | |

1332 | @cindex Macros as environment wrappers | |
1333 | @cindex Figure wrapping macro | |
1334 | ||
1335 | Suppose you want to make figures not directly with the figure | |
1336 | environment, but with a macro like | |
1337 | ||
1338 | @example | |
1339 | \newcommand@{\myfig@}[5][tbp]@{% | |
1340 | \begin@{figure@}[#1] | |
1341 | \epsimp[#5]@{#2@} | |
1342 | \caption@{#3@} | |
1343 | \label@{#4@} | |
1344 | \end@{figure@}@} | |
1345 | @end example | |
1346 | ||
1347 | @noindent | |
1348 | which would be called like | |
1349 | ||
1350 | @example | |
1351 | \myfig[htp]@{filename@}@{caption text@}@{label@}@{1@} | |
1352 | @end example | |
1353 | ||
1354 | Now we need to tell @b{Ref@TeX{}} that the 4th argument of the | |
1355 | @code{\myfig} macro @emph{is itself} a figure label, and where to find | |
1356 | the context. | |
1357 | ||
1358 | @lisp | |
1359 | (setq reftex-label-alist | |
1360 | '(("\\myfig[]@{@}@{@}@{*@}@{@}" ?f nil nil 3))) | |
1361 | @end lisp | |
1362 | ||
1363 | The empty pairs of brackets indicate the different arguments of the | |
1364 | @code{\myfig} macro. The @samp{*} marks the label argument. @code{?f} | |
1365 | indicates that this is a figure label which will be listed together with | |
1366 | labels from normal figure environments. The @code{nil} entries for | |
1367 | prefix and reference format mean to use the defaults for figure labels. | |
1368 | The @samp{3} for the context method means to grab the 3rd macro argument | |
1369 | - the caption. | |
1370 | ||
1371 | As a side effect of this configuration, @code{reftex-label} will now | |
1372 | insert the required naked label (without the @code{\label} macro) when | |
1373 | point is directly after the opening parenthesis of a @code{\myfig} macro | |
1374 | argument. | |
1375 | ||
1376 | Again, here the configuration in the customization buffer: | |
1377 | ||

1396 | Sometimes you don't want to define a new label environment or macro, but | |
1397 | just change the information associated with a label category. Maybe you | |
1398 | want to add some magic words, for another language. Changing only the | |
1399 | information associated with a label category is done by giving | |
1400 | @code{nil} for the environment name and then specify the items you want | |
1401 | to define. Here is an example which adds German magic words to all | |
1402 | predefined label categories. | |
1403 | ||
1404 | @lisp | |
1405 | (setq reftex-label-alist | |

1419 | ||
1420 | Another case where one only wants to change the information associated | |
1421 | with the label category is to change the macro which is used for | |
1422 | referencing the label. When working with the AMS-LaTeX stuff, you might | |
1423 | prefer @code{\eqref} for doing equation references. Here is how to | |
1424 | do this: | |
1425 | ||
1426 | @lisp | |
1427 | (setq reftex-label-alist '((nil ?e nil "~\\eqref@{%s@}" nil nil))) | |
1428 | @end lisp | |
1429 | ||
1430 | @b{Ref@TeX{}} has also a predefined symbol for this special purpose. The | |

1433 | @lisp | |
1434 | (setq reftex-label-alist '(AMSTeX)) | |

1445 | @cindex Special parser functions | |
1446 | @cindex Parser functions, for special environments | |
1447 | ||
1448 | Some LaTeX packages define environment-like structures without using the | |
1449 | standard @samp{\begin..\end} structure. @b{Ref@TeX{}} cannot parse | |
1450 | these directly, but you can write your own special-purpose parser and | |
1451 | use it instead of the name of an environment in an entry for | |
1452 | @code{reftex-label-alist}. The function should check if point is | |
1453 | currently in the special environment it was written to detect. If so, | |
1454 | it must return a buffer position indicating the start of this | |
1455 | environment. The return value must be @code{nil} on failure to detect | |
1456 | the environment. The function is called with one argument @var{bound}. | |
1457 | If non-@code{nil}, @var{bound} is a boundary for backwards searches | |
1458 | which should be observed. We will discuss two examples. | |
1459 | ||
1460 | @cindex LaTeX commands, abbreviated | |
1461 | ||
1462 | Some people define abbreviations for | |
1463 | environments, like @code{\be} for @code{\begin@{equation@}}, and | |
1464 | @code{\ee} for @code{\end@{equation@}}. The parser function would have | |
1465 | to search backward for these macros. When the first match is | |
1466 | @code{\ee}, point is not in this environment. When the first match is | |
1467 | @code{\be}, point is in this environment and the function must return | |
1468 | the beginning of the match. To avoid scanning too far, we can also look | |
1469 | for empty lines which cannot occur inside an equation environment. | |
1470 | Here is the setup: | |
1471 | ||
1472 | @lisp | |
1473 | ;; Setup entry in reftex-label-alist, using all defaults for equations | |
1474 | (setq reftex-label-alist '((detect-be-ee ?e nil nil nil nil))) | |
1475 | ||

1488 | A more complex example is the @file{linguex.sty} package which defines | |
1489 | list macros @samp{\ex.}, @samp{\a.}, @samp{\b.} etc. for lists which are | |
1490 | terminated by @samp{\z.} or by an empty line. | |
1491 | ||
1492 | @example | |
1493 | \ex. \label@{ex:12@} Some text in an exotic language ... | |
1494 | \a. \label@{ex:13@} more stuff | |
1495 | \b. \label@{ex:14@} still more stuff | |
1496 | \a. List on a deeper level | |
1497 | \b. Another item | |

1501 | ||
1502 | ... text after the empty line terminating all lists | |
1503 | @end example | |
1504 | ||
1505 | The difficulty is that the @samp{\a.} lists can nest and that an empty | |
1506 | line terminates all list levels in one go. So we have to count nesting | |
1507 | levels between @samp{\a.} and @samp{\z.}. Here is the implementation | |

1597 | \externaldocument[V1-]@{volume1@} | |
1598 | \externaldocument[V3-]@{volume3@} | |
1599 | @end example | |
1600 | ||
1601 | @noindent | |
1602 | and we can make references to any labels defined in these | |
1603 | external documents by using the prefixes @samp{V1-} and @samp{V3-}, | |
1604 | respectively. | |
1605 | ||
1606 | @b{Ref@TeX{}} can be used to create such references as well. Start the | |
1607 | referencing process normally, by pressing @kbd{C-c )}. Select a label | |
1608 | type if necessary. When you see the label selection buffer, pressing | |
1609 | @kbd{x} will switch to the label selection buffer of one of the external | |
1610 | documents. You may then select a label as before and @b{Ref@TeX{}} will | |
1611 | insert it along with the required prefix. | |
1612 | ||

1829 | The standard LaTeX macro @code{\cite} works well with numeric or simple | |
1830 | key citations. To deal with the more complex task of author-year | |
1831 | citations as used in many natural sciences, a variety of packages has | |
1832 | been developed which define derived forms of the @code{\cite} macro. | |
1833 | @b{Ref@TeX{}} can be configured to produce these citation macros as well | |
1834 | by setting the variable @code{reftex-cite-format}. For the most | |
1835 | commonly used packages (@code{natbib}, @code{harvard}, @code{chicago}, | |
1836 | @code{jurabib}) this may be done from the menu, under | |
1837 | @code{Ref->Citation Styles}. Since there are usually several macros to | |
1838 | create the citations, executing @code{reftex-citation} (@kbd{C-c [}) | |
1839 | starts by prompting for the correct macro. For the Natbib style, this | |
1840 | looks like this: | |
1841 | ||
1842 | @example | |
1843 | SELECT A CITATION FORMAT | |
1844 | ||

1858 | If cite formats contain empty paris of square brackets, RefTeX can | |
1859 | will prompt for values of these optional arguments if you call the | |
1860 | @code{reftex-citation} command with a @kbd{C-u} prefix. | |
1861 | Following the most generic of these packages, @code{natbib}, the builtin | |
1862 | citation packages always accept the @kbd{t} key for a @emph{textual} | |
1863 | citation (like: @code{Jones et al. (1997) have shown...}) as well as | |
1864 | the @kbd{p} key for a parenthetical citation (like: @code{As shown | |
1865 | earlier (Jones et al, 1997)}). | |
1866 | ||
1867 | To make one of these styles the default, customize the variable | |

1944 | ||
1945 | @b{Ref@TeX{}} offers two ways to create a new BibTeX database file. | |
1946 | ||
1947 | The first option produces a file which contains only the entries | |
1948 | actually referenced in the current document. This can be useful if | |
1949 | the database in only meant for a single document and you want to clean | |
1950 | it of old and unused ballast. It can also be useful while writing a | |
1951 | document together with collaborators, in order to avoid sending around | |
1952 | the entire (possibly very large) database. To create the file, use | |
1953 | @kbd{M-x reftex-create-bibtex-file}, also available from the menu | |
1954 | under @code{Ref->Global Actions->Create Bibtex File}. The command will | |
1955 | prompt for a BibTeX file name and write the extracted entries to that | |
1956 | file. | |
1957 | ||
1958 | The second option makes use of the selection process started by the | |
1959 | command @kbd{C-c [} (@pxref{Creating Citations}). This command uses a | |
1960 | regular expression to select entries, and lists them in a formatted | |
1961 | selection buffer. After pressing the @kbd{e} key (mnemonics: Export), | |
1962 | the command will prompt for the name of a new BibTeX file and write | |
1963 | the selected entries to that file. You can also first mark some | |
1964 | entries in the selection buffer with the @kbd{m} key and then export | |
1965 | either the @i{marked} entries (with the @kbd{e} key) or the | |
1966 | @i{unmarked} entries (with the @kbd{E} key). | |

1971 | @cindex @code{\index} | |
1972 | ||
1973 | LaTeX has builtin support for creating an Index. The LaTeX core | |
1974 | supports two different indices, the standard index and a glossary. With | |
1975 | the help of special LaTeX packages (@file{multind.sty} or | |
1976 | @file{index.sty}), any number of indices can be supported. | |
1977 | ||
1978 | Index entries are created with the @code{\index@{@var{entry}@}} macro. | |
1979 | All entries defined in a document are written out to the @file{.aux} | |
1980 | file. A separate tool must be used to convert this information into a | |
1981 | nicely formatted index. Tools used with LaTeX include @code{MakeIndex} | |
1982 | and @code{xindy}. | |
1983 | ||
1984 | Indexing is a very difficult task. It must follow strict conventions to | |
1985 | make the index consistent and complete. There are basically two | |
1986 | approaches one can follow, and both have their merits. | |
1987 | ||
1988 | @enumerate | |
1989 | @item | |
1990 | Part of the indexing should already be done with the markup. The | |
1991 | document structure should be reflected in the index, so when starting | |
1992 | new sections, the basic topics of the section should be indexed. If the | |
1993 | document contains definitions, theorems or the like, these should all | |
1994 | correspond to appropriate index entries. This part of the index can | |
1995 | very well be developed along with the document. Often it is worthwhile | |
1996 | to define special purpose macros which define an item and at the same | |
1997 | time make an index entry, possibly with special formatting to make the | |
1998 | reference page in the index bold or underlined. To make @b{Ref@TeX{}} | |
1999 | support for indexing possible, these special macros must be added to | |
2000 | @b{Ref@TeX{}}'s configuration (@pxref{Defining Index Macros}). | |
2001 | ||
2002 | @item | |
2003 | The rest of the index is often just a collection of where in the | |
2004 | document certain words or phrases are being used. This part is | |
2005 | difficult to develop along with the document, because consistent entries | |
2006 | for each occurrence are needed and are best selected when the document | |
2007 | is ready. @b{Ref@TeX{}} supports this with an @emph{index phrases file} | |
2008 | which collects phrases and helps indexing the phrases globally. | |
2009 | @end enumerate | |
2010 | ||
2011 | Before you start, you need to make sure that @b{Ref@TeX{}} knows about | |
2012 | the index style being used in the current document. @b{Ref@TeX{}} has | |
2013 | builtin support for the default @code{\index} and @code{\glossary} | |
2014 | macros. Other LaTeX packages, like the @file{multind} or @file{index} | |
2015 | package, redefine the @code{\index} macro to have an additional | |
2016 | argument, and @b{Ref@TeX{}} needs to be configured for those. A | |
2017 | sufficiently new version of AUCTeX (9.10c or later) will do this | |
2018 | automatically. If you really don't use AUCTeX (you should!), this | |
2019 | configuration needs to be done by hand with the menu (@code{Ref->Index | |

2140 | @code{<TABs>} stands for white space containing at least one @key{TAB}. | |
2141 | @var{key} must be at the start of the line and is the character | |
2142 | identifying one of the macros defined in the file header. It is | |
2143 | optional - when omitted, the first macro definition line in the file | |
2144 | will be used for this phrase. The @var{phrase} is the phrase to be | |
2145 | searched for when indexing. It may contain several words separated by | |
2146 | spaces. By default the search phrase is also the text entered as | |
2147 | argument of the index macro. If you want the index entry to be | |
2148 | different from the search phrase, enter another @key{TAB} and the index | |
2149 | argument @var{arg}. If you want to have each match produce several | |
2150 | index entries, separate the different index arguments with @samp{ && | |
2151 | }@footnote{@samp{&&} with optional spaces, see | |
2152 | @code{reftex-index-phrases-logical-and-regexp}.}. If you want to be | |
2153 | able to choose at each match between several different index arguments, | |
2154 | separate them with @samp{ || }@footnote{@samp{||} with optional spaces, | |
2155 | see @code{reftex-index-phrases-logical-or-regexp}.}. Here is an | |
2156 | example: | |
2157 | ||
2158 | @example | |
2159 | %-------------------------------------------------------------------- | |
2160 | I Sun | |
2161 | i Planet Planets | |
2162 | i Vega Stars!Vega | |
2163 | Jupiter Planets!Jupiter | |
2164 | i Mars Planets!Mars || Gods!Mars || Chocolate Bars!Mars | |
2165 | i Pluto Planets!Pluto && Kuiper Belt Objects!Pluto | |
2166 | @end example | |
2167 | ||
2168 | ||
2169 | So @samp{Sun} will be indexed directly as @samp{\index*@{Sun@}}, while | |
2170 | @samp{Planet} will be indexed as @samp{\index@{Planets@}Planet}. | |
2171 | @samp{Vega} will be indexed as a subitem of @samp{Stars}. The | |
2172 | @samp{Jupiter} line will also use the @samp{i} macro as it was the first | |
2173 | macro definition in the file header (see above example). At each | |
2174 | occurrence of @samp{Mars} you will be able choose between indexing it as | |
2175 | a subitem of @samp{Planets}, @samp{Gods} or @samp{Chocolate Bars}. | |
2176 | Finally, every occurrence of @samp{Pluto} will be indexed as | |
2177 | @samp{\index@{Planets!Pluto@}\index@{Kuiper Belt Objects!Pluto@}Pluto} | |
2178 | and will therefore create two different index entries. | |

2185 | ||
2186 | @kindex C-c C-s | |
2187 | Before indexing the phrases in the phrases buffer, they should be | |
2188 | checked carefully for consistency. A first step is to sort the phrases | |
2189 | alphabetically - this is done with the command @kbd{C-c C-s} | |
2190 | (@code{reftex-index-sort-phrases}). It will sort all phrases in the | |
2191 | buffer alphabetically by search phrase. If you want to group certain | |
2192 | phrases and only sort within the groups, insert empty lines between the | |
2193 | groups. Sorting will only change the sequence of phrases within each | |
2194 | group (see the variable @code{reftex-index-phrases-sort-in-blocks}). | |
2195 | ||
2196 | @kindex C-c C-i | |
2197 | A useful command is @kbd{C-c C-i} (@code{reftex-index-phrases-info}) | |
2198 | which lists information about the phrase at point, including an example | |
2199 | of how the index entry will look like and the number of expected matches | |
2200 | in the document. | |
2201 | ||
2202 | @kindex C-c C-t | |
2203 | Another important check is to find out if there are double or | |
2204 | overlapping entries in the buffer. For example if you are first | |
2205 | searching and indexing @samp{Mars} and then @samp{Planet Mars}, the | |
2206 | second phrase will not match because of the index macro inserted before | |
2207 | @samp{Mars} earlier. The command @kbd{C-c C-t} | |
2208 | (@code{reftex-index-find-next-conflict-phrase}) finds the next phrase in | |
2209 | the buffer which is either duplicate or a subphrase of another phrase. | |
2210 | In order to check the whole buffer like this, start at the beginning and | |
2211 | execute this command repeatedly. | |

2217 | @cindex Indexing, from @file{phrases} buffer | |
2218 | ||
2219 | Once the index phrases have been collected and organized, you are set | |
2220 | for global indexing. I recommend to do this only on an otherwise | |
2221 | finished document. Global indexing starts from the phrases buffer. | |
2222 | There are several commands which start indexing: @kbd{C-c C-x} acts on | |
2223 | the current phrase line, @kbd{C-c C-r} on all lines in the current | |
2224 | region and @kbd{C-c C-a} on all phrase lines in the buffer. It is | |
2225 | probably good to do indexing in small chunks since your concentration | |
2226 | may not last long enough to do everything in one go. | |
2227 | ||
2228 | @b{Ref@TeX{}} will start at the first phrase line and search the phrase | |
2229 | globally in the whole document. At each match it will stop, compute the | |
2230 | replacement string and offer you the following choices@footnote{Windows | |
2231 | users: Restrict yourself to the described keys during indexing. Pressing | |
2232 | @key{Help} at the indexing prompt can apparently hang Emacs.}: | |
2233 | ||
2234 | @table @kbd | |
2235 | @item y | |
2236 | Replace this match with the proposed string. | |
2237 | @item n | |
2238 | Skip this match. | |
2239 | @item ! | |

2256 | Save all document buffers and ask again about the current match. | |
2257 | @item C-g | |
2258 | Abort the indexing process. | |
2259 | @end table | |
2260 | ||
2261 | The @samp{Find and Index in Document} menu in the phrases buffer also | |
2262 | lists a few options for the indexing process. The options have | |
2263 | associated customization variables to set the defaults (@pxref{Options | |
2264 | (Index Support)}). Here is a short explanation of what the options do: | |
2265 | ||
2266 | @table @i | |
2267 | @item Match Whole Words | |
2268 | When searching for index phrases, make sure whole words are matched. | |
2269 | This should probably always be on. | |
2270 | @item Case Sensitive Search | |
2271 | Search case sensitively for phrases. I recommend to have this setting | |
2272 | off, in order to match the capitalized words at the beginning of a | |
2273 | sentence, and even typos. You can always say @emph{no} at a match you | |
2274 | do not like. | |
2275 | @item Wrap Long Lines | |
2276 | Inserting index macros increases the line length. Turn this option on | |
2277 | to allow @b{Ref@TeX{}} to wrap long lines. | |
2278 | @item Skip Indexed Matches | |
2279 | When this is on, @b{Ref@TeX{}} will at each match try to figure out if | |
2280 | this match is already indexed. A match is considered indexed if it is | |
2281 | either the argument of an index macro, or if an index macro is directly | |
2282 | (without whitespace separation) before or after the match. Index macros | |
2283 | are those configured in @code{reftex-index-macros}. Intended for | |
2284 | re-indexing a documents after changes have been made. | |
2285 | @end table | |
2286 | ||
2287 | Even though indexing should be the last thing you do to a document, you | |
2288 | are bound to make changes afterwards. Indexing then has to be applied | |
2289 | to the changed regions. The command | |
2290 | @code{reftex-index-phrases-apply-to-region} is designed for this | |
2291 | purpose. When called from a LaTeX document with active region, it will | |
2292 | apply @code{reftex-index-all-phrases} to the current region. | |

2303 | ||
2304 | In order to compile and display the index, press @kbd{C-c >}. If the | |
2305 | document uses multiple indices, @b{Ref@TeX{}} will ask you to select | |
2306 | one. Then, all index entries will be sorted alphabetically and | |
2307 | displayed in a special buffer, the @file{*Index*} buffer. From that | |
2308 | buffer you can check and edit each entry. | |
2309 | ||
2310 | The index can be restricted to the current section or the region. Then | |
2311 | only entries in that part of the document will go into the compiled | |
2312 | index. To restrict to the current section, use a numeric prefix | |
2313 | @samp{2}, thus press @kbd{C-u 2 C-c >}. To restrict to the current | |
2314 | region, make the region active and use a numeric prefix @samp{3} (press | |
2315 | @kbd{C-u 3 C-c >}). From within the @file{*Index*} buffer the | |
2316 | restriction can be moved from one section to the next by pressing the | |
2317 | @kbd{<} and @kbd{>} keys. | |
2318 | ||
2319 | One caveat: @b{Ref@TeX{}} finds the definition point of an index entry | |
2320 | by searching near the buffer position where it had found to macro during | |
2321 | scanning. If you have several identical index entries in the same | |
2322 | buffer and significant changes have shifted the entries around, you must | |
2323 | rescan the buffer to ensure the correspondence between the | |
2324 | @file{*Index*} buffer and the definition locations. It is therefore | |
2325 | advisable to rescan the document (with @kbd{r} or @kbd{C-u r}) | |
2326 | frequently while editing the index from the @file{*Index*} | |
2327 | buffer. | |
2328 | ||
2329 | @kindex ? | |
2330 | Here is a list of special commands available in the @file{*Index*} buffer. A | |

2343 | @item ! A..Z | |
2344 | Pressing any capital letter will jump to the corresponding section in | |
2345 | the @file{*Index*} buffer. The exclamation mark is special and jumps to | |
2346 | the first entries alphabetically sorted below @samp{A}. These are | |
2347 | usually non-alphanumeric characters. | |

2369 | always show the location corresponding to the line in the @file{*Index*} | |
2370 | buffer at point. This is similar to pressing @key{SPC} after each | |
2371 | cursor motion. The default for this flag can be set with the variable | |
2372 | @code{reftex-index-follow-mode}. Note that only context in files | |
2373 | already visited is shown. @b{Ref@TeX{}} will not visit a file just for | |

2386 | @item * | |
2387 | Edit the @var{key} part of the entry. This is the initial part of the | |
2388 | entry which determines the location of the entry in the index. | |
2389 | ||
2390 | @item | | |
2391 | Edit the @var{attribute} part of the entry. This is the part after the | |
2392 | vertical bar. With @code{MakeIndex}, this part is an encapsulating | |
2393 | macro. With @code{xindy}, it is called @emph{attribute} and is a | |
2394 | property of the index entry that can lead to special formatting. When | |
2395 | called with @kbd{C-u} prefix, kill the entire @var{attribute} | |
2396 | part. | |
2397 | ||
2398 | @item @@ | |
2399 | Edit the @var{visual} part of the entry. This is the part after the | |
2400 | @samp{@@} which is used by @code{MakeIndex} to change the visual | |
2401 | appearance of the entry in the index. When called with @kbd{C-u} | |

2496 | @cindex Index macros, defining | |
2497 | @vindex reftex-index-macros | |
2498 | ||
2499 | When writing a document with an index you will probably define | |
2500 | additional macros which make entries into the index. | |
2501 | Let's look at an example. | |
2502 | ||
2503 | @example | |
2504 | \newcommand@{\ix@}[1]@{#1\index@{#1@}@} | |
2505 | \newcommand@{\nindex@}[1]@{\textit@{#1@}\index[name]@{#1@}@} | |
2506 | \newcommand@{\astobj@}[1]@{\index@{Astronomical Objects!#1@}@} | |
2507 | @end example | |
2508 | ||
2509 | The first macro @code{\ix} typesets its argument in the text and places | |
2510 | it into the index. The second macro @code{\nindex} typesets its | |
2511 | argument in the text and places it into a separate index with the tag | |
2512 | @samp{name}@footnote{We are using the syntax of the @file{index} package | |
2513 | here.}. The last macro also places its argument into the index, but as | |
2514 | subitems under the main index entry @samp{Astronomical Objects}. Here | |
2515 | is how to make @b{Ref@TeX{}} recognize and correctly interpret these | |
2516 | macros, first with Emacs Lisp. | |
2517 | ||
2518 | @lisp | |
2519 | (setq reftex-index-macros | |
2520 | '(("\\ix@{*@}" "idx" ?x "" nil nil) | |
2521 | ("\\nindex@{*@}" "name" ?n "" nil nil) | |
2522 | ("\\astobj@{*@}" "idx" ?o "Astronomical Objects!" nil t))) | |
2523 | @end lisp | |
2524 | ||
2525 | Note that the index tag is @samp{idx} for the main index, and | |
2526 | @samp{name} for the name index. @samp{idx} and @samp{glo} are reserved | |
2527 | for the default index and for the glossary. | |
2528 | ||
2529 | The character arguments @code{?x}, @code{?n}, and @code{?o} are for | |
2530 | quick identification of these macros when @b{Ref@TeX{}} inserts new | |
2531 | index entries with @code{reftex-index}. These codes need to be | |
2532 | unique. @code{?i}, @code{?I}, and @code{?g} are reserved for the | |
2533 | @code{\index}, @code{\index*}, and @code{\glossary} macros, | |
2534 | respectively. | |
2535 | ||
2536 | The following string is empty unless your macro adds a superordinate | |
2537 | entry to the index key - this is the case for the @code{\astobj} macro. | |
2538 | ||
2539 | The next entry can be a hook function to exclude certain matches, it | |
2540 | almost always can be @code{nil}. | |
2541 | ||
2542 | The final element in the list indicates if the text being indexed needs | |
2543 | to be repeated outside the macro. For the normal index macros, this | |
2544 | should be @code{t}. Only if the macro typesets the entry in the text | |
2545 | (like @code{\ix} and @code{\nindex} in the example do), this should be | |
2546 | @code{nil}. | |
2547 | ||
2548 | To do the same thing with customize, you need to fill in the templates | |
2549 | like this: | |
2550 | ||
2551 | @example | |
2552 | Repeat: | |

2783 | @item | |
2784 | @vindex tex-main-file | |

2786 | All files belonging to a multifile document should define a File | |
2787 | Variable (@code{TeX-master} for AUCTeX or @code{tex-main-file} for the | |
2788 | standard Emacs LaTeX mode) containing the name of the master file. For | |
2789 | example, to set the file variable @code{TeX-master}, include something | |
2790 | like the following at the end of each TeX file: | |
2791 | ||
2792 | @example | |
2793 | %%% Local Variables: *** | |
2794 | %%% mode:latex *** | |

2838 | @vindex reftex-translate-to-ascii-function | |
2839 | @vindex reftex-label-illegal-re | |
2840 | Also, when a label is derived from context, @b{Ref@TeX{}} clears the | |
2841 | context string from non-ASCII characters in order to make a valid label. | |
2842 | If there should ever be a version of @TeX{} which allows extended | |
2843 | characters @emph{in labels}, then we will have to look at the | |
2844 | variables @code{reftex-translate-to-ascii-function} and | |
2845 | @code{reftex-label-illegal-re}. | |
2846 | ||
2847 | @item | |
2848 | When a label is referenced, @b{Ref@TeX{}} looks at the word before point | |
2849 | to guess which label type is required. These @emph{magic words} are | |

2864 | @cindex Finding files | |
2865 | ||
2866 | In order to find files included in a document via @code{\input} or | |
2867 | @code{\include}, @b{Ref@TeX{}} searches all directories specified in the | |
2868 | environment variable @code{TEXINPUTS}. Similarly, it will search the | |
2869 | path specified in the variables @code{BIBINPUTS} and @code{TEXBIB} for | |
2870 | BibTeX database files. | |
2871 | ||
2872 | When searching, @b{Ref@TeX{}} will also expand recursive path | |
2873 | definitions (directories ending in @samp{//} or @samp{!!}). But it will | |
2874 | only search and expand directories @emph{explicitly} given in these | |
2875 | variables. This may cause problems under the following circumstances: | |
2876 | ||
2877 | @itemize @bullet | |
2878 | @item | |
2879 | Most TeX system have a default search path for both TeX files and BibTeX | |
2880 | files which is defined in some setup file. Usually this default path is | |
2881 | for system files which @b{Ref@TeX{}} does not need to see. But if your | |
2882 | document needs TeX files or BibTeX database files in a directory only | |
2883 | given in the default search path, @b{Ref@TeX{}} will fail to find them. | |
2884 | @item | |
2885 | Some TeX systems do not use environment variables at all in order to | |
2886 | specify the search path. Both default and user search path are then | |
2887 | defined in setup files. | |
2888 | @end itemize | |
2889 | ||
2890 | @noindent | |
2891 | There are three ways to solve this problem: | |
2892 | ||
2893 | @itemize @bullet | |
2894 | @item | |
2895 | Specify all relevant directories explicitly in the environment | |
2896 | variables. If for some reason you don't want to mess with the default | |
2897 | variables @code{TEXINPUTS} and @code{BIBINPUTS}, define your own | |
2898 | variables and configure @b{Ref@TeX{}} to use them instead: | |
2899 | ||
2900 | @lisp | |
2901 | (setq reftex-texpath-environment-variables '("MYTEXINPUTS")) | |
2902 | (setq reftex-bibpath-environment-variables '("MYBIBINPUTS")) | |
2903 | @end lisp | |

2908 | @lisp | |
2909 | (setq reftex-texpath-environment-variables | |
2910 | '("./inp:/home/cd/tex//:/usr/local/tex//")) | |

2913 | @end lisp | |
2914 | ||
2915 | @item | |
2916 | Some TeX systems provide stand--alone programs to do the file search just | |
2917 | like TeX and BibTeX. E.g. Thomas Esser's @code{teTeX} uses the | |
2918 | @code{kpathsearch} library which provides the command @code{kpsewhich} | |
2919 | to search for files. @b{Ref@TeX{}} can be configured to use this | |
2920 | program. Note that the exact syntax of the @code{kpsewhich} | |
2921 | command depends upon the version of that program. | |

2938 | the new extension must also be known to AUCTeX via the variable | |

2984 | re-parsing of the entire document in order to update the parsing | |

2987 | to do partial scans instead of full ones. @kbd{C-u} re-parsing then | |
2988 | does apply only to the current buffer and files included from it. | |
2989 | Likewise, the @kbd{r} key in both the label selection buffer and the | |
2990 | table-of-contents buffer will only prompt scanning of the file in which | |
2991 | the label or section macro near the cursor was defined. Re-parsing of | |

3006 | Even with partial scans enabled, @b{Ref@TeX{}} still has to make one full | |
3007 | scan, when you start working with a document. To avoid this, parsing | |
3008 | information can be stored in a file. The file @file{MASTER.rel} is used | |
3009 | for storing information about a document with master file | |
3010 | @file{MASTER.tex}. It is written automatically when you kill a buffer | |
3011 | in @code{reftex-mode} or when you exit Emacs. The information is | |
3012 | restored when you begin working with a document in a new editing | |

3023 | @vindex reftex-trust-label-prefix | |
3024 | @b{Ref@TeX{}} normally parses around each label to check in which | |
3025 | environment this label is located, in order to assign a label type to | |
3026 | the label. If your document contains thousands of labels, document | |
3027 | parsing will take considerable time. If you have been using label prefixes | |
3028 | like tab: and fn: consistently, you can tell @b{Ref@TeX{}} to get the | |
3029 | label type directly from the prefix, without additional parsing. This | |
3030 | will be faster and also allow labels to end up in the correct category | |
3031 | if for some reason it is not possible to derive the correct type from | |
3032 | context. For example, to enable this feature for footnote and | |
3033 | equation labels, use | |

3059 | Normally, the selection buffer @file{*RefTeX Select*} is re-created for | |
3060 | every selection process. In documents with very many labels this can | |
3061 | take several seconds. @b{Ref@TeX{}} provides an option to create a | |
3062 | separate selection buffer for each label type and to keep this buffer | |
3063 | from one selection to the next. These buffers are updated automatically | |
3064 | only when a new label has been added in the buffers category with | |
3065 | @code{reftex-label}. Updating the buffer takes as long as recreating it | |
3066 | - so the time saving is limited to cases where no new labels of that | |

3119 | @subsection The AUC@TeX{}-@b{Ref@TeX{}} Interface | |
3120 | ||
3121 | @b{Ref@TeX{}} contains code to interface with AUCTeX. When this | |
3122 | interface is turned on, both packages will interact closely. Instead of | |
3123 | using @b{Ref@TeX{}}'s commands directly, you can then also use them | |
3124 | indirectly as part of the AUCTeX | |
3125 | environment@footnote{@b{Ref@TeX{}} 4.0 and AUCTeX 9.10c will be | |
3126 | needed for all of this to work. Parts of it work also with earlier | |
3127 | versions.}. The interface is turned on with | |
3128 | ||
3129 | @lisp | |
3130 | (setq reftex-plug-into-AUCTeX t) | |
3131 | @end lisp | |
3132 | ||
3133 | If you need finer control about which parts of the interface are used | |
3134 | and which not, read the docstring of the variable | |
3135 | @code{reftex-plug-into-AUCTeX} or customize it with @kbd{M-x | |
3136 | customize-variable @key{RET} reftex-plug-into-AUCTeX @key{RET}}. | |
3137 | ||
3138 | The following list describes the individual parts of the interface. | |

3148 | @b{AUCTeX calls @code{reftex-label} to insert labels}@* | |
3149 | When a new section is created with @kbd{C-c C-s}, or a new environment | |
3150 | is inserted with @kbd{C-c C-e}, AUCTeX normally prompts for a label to | |
3151 | go with it. With the interface, @code{reftex-label} is called instead. | |
3152 | For example, if you type @kbd{C-c C-e equation @key{RET}}, AUCTeX and | |
3153 | @b{Ref@TeX{}} will insert | |
3154 | ||
3155 | @example | |
3156 | \begin@{equation@} | |
3157 | \label@{eq:1@} | |

3160 | @end example | |
3161 | ||

3163 | without further prompts. | |
3164 | ||
3165 | Similarly, when you type @kbd{C-c C-s section @key{RET}}, @b{Ref@TeX{}} | |
3166 | will offer its default label which is derived from the section title. | |

3184 | @b{@b{Ref@TeX{}} supplies macro arguments}@* When you insert a macro | |
3185 | interactively with @kbd{C-c @key{RET}}, AUCTeX normally prompts for | |
3186 | macro arguments. Internally, it uses the functions | |
3187 | @code{TeX-arg-label}, @code{TeX-arg-cite}, and @code{TeX-arg-index} to | |
3188 | prompt for arguments which are labels, citation keys and index entries. | |
3189 | The interface takes over these functions@footnote{@code{fset} is used to | |
3190 | do this, which is not reversible. However, @b{Ref@TeX{}} implements the | |
3191 | old functionality when you later decide to turn off the interface.} and | |
3192 | supplies the macro arguments with @b{Ref@TeX{}'s} mechanisms. For | |
3193 | example, when you type @kbd{C-c @key{RET} ref @key{RET}}, @b{Ref@TeX{}} | |
3194 | will supply its label selection process (@pxref{Referencing | |

3203 | @subsection Style Files | |
3204 | @cindex Style files, AUCTeX | |
3205 | @findex TeX-add-style-hook, @r{AUCTeX} | |
3206 | Style files are Emacs Lisp files which are evaluated by AUCTeX in | |
3207 | association with the @code{\documentclass} and @code{\usepackage} | |
3208 | commands of a document (@pxref{Style Files,,,auctex}). Support for | |
3209 | @b{Ref@TeX{}} in such a style file is useful when the LaTeX style | |
3210 | defines macros or environments connected with labels, citations, or the | |
3211 | index. Many style files (e.g. @file{amsmath.el} or @file{natbib.el}) | |
3212 | distributed with AUCTeX already support @b{Ref@TeX{}} in this | |
3213 | way. | |
3214 | ||
3215 | Before calling a @b{Ref@TeX{}} function, the style hook should always | |
3216 | test for the availability of the function, so that the style file will | |
3217 | also work for people who do not use @b{Ref@TeX{}}. | |
3218 | ||
3219 | Additions made with style files in the way described below remain local | |
3220 | to the current document. For example, if one package uses AMSTeX, the | |
3221 | style file will make @b{Ref@TeX{}} switch over to @code{\eqref}, but | |
3222 | this will not affect other documents. | |
3223 | ||
3224 | @findex reftex-add-label-environments | |
3225 | @findex reftex-add-to-label-alist | |
3226 | A style hook may contain calls to | |
3227 | @code{reftex-add-label-environments}@footnote{This used to be the | |
3228 | function @code{reftex-add-to-label-alist} which is still available as an | |
3229 | alias for compatibility.} which defines additions to | |
3230 | @code{reftex-label-alist}. The argument taken by this function must have | |
3231 | the same format as @code{reftex-label-alist}. The @file{amsmath.el} | |
3232 | style file of AUCTeX for example contains the following: | |
3233 | ||
3234 | @lisp | |
3235 | @group | |
3236 | (TeX-add-style-hook "amsmath" | |
3237 | (lambda () | |

3258 | @end lisp | |
3259 | ||
3260 | @findex reftex-set-cite-format | |
3261 | Similarly, a style hook may contain a call to | |
3262 | @code{reftex-set-cite-format} to set the citation format. The style | |
3263 | file @file{natbib.el} for the Natbib citation style does switch | |
3264 | @b{Ref@TeX{}}'s citation format like this: | |
3265 | ||
3266 | @lisp | |
3267 | (TeX-add-style-hook "natbib" | |
3268 | (lambda () | |
3269 | (if (fboundp 'reftex-set-cite-format) | |

3271 | @end lisp | |
3272 | ||
3273 | @findex reftex-add-index-macros | |
3274 | The hook may contain a call to @code{reftex-add-index-macros} to | |
3275 | define additional @code{\index}-like macros. The argument must have | |
3276 | the same format as @code{reftex-index-macros}. It may be a symbol, to | |
3277 | trigger support for one of the builtin index packages. For example, | |
3278 | the style @file{multind.el} contains | |
3279 | ||
3280 | @lisp | |
3281 | (TeX-add-style-hook "multind" | |
3282 | (lambda () | |
3283 | (and (fboundp 'reftex-add-index-macros) | |
3284 | (reftex-add-index-macros '(multind))))) | |
3285 | @end lisp | |
3286 | ||
3287 | If you have your own package @file{myindex} which defines the | |
3288 | following macros to be used with the LaTeX @file{index.sty} file | |
3289 | @example | |
3290 | \newcommand@{\molec@}[1]@{#1\index@{Molecules!#1@}@} | |
3291 | \newcommand@{\aindex@}[1]@{#1\index[author]@{#1@} | |
3292 | @end example | |
3293 | ||
3294 | you could write this in the style file @file{myindex.el}: | |
3295 | ||
3296 | @lisp | |
3297 | (TeX-add-style-hook "myindex" | |
3298 | (lambda () | |
3299 | (TeX-add-symbols | |

3307 | ||
3308 | @findex reftex-add-section-levels | |
3309 | Finally the hook may contain a call to @code{reftex-add-section-levels} | |
3310 | to define additional section statements. For example, the FoilTeX class | |
3311 | has just two headers, @code{\foilhead} and @code{\rotatefoilhead}. Here | |
3312 | is a style file @file{foils.el} that will inform @b{Ref@TeX{}} about these: | |
3313 | ||
3314 | @lisp | |
3315 | (TeX-add-style-hook "foils" | |
3316 | (lambda () | |
3317 | (if (fboundp 'reftex-add-section-levels) | |

3327 | Once you have written a document with labels, references and citations, | |

3330 | &}), @code{reftex-mouse-view-crossref} (bound to @kbd{S-mouse-2}), and | |
3331 | @code{reftex-search-document}. A somewhat fancier interface with mouse | |
3332 | highlighting is provided (among other things) by Peter S. Galbraith's | |
3333 | @file{bib-cite.el}. There is some overlap in the functionalities of | |
3334 | Bib-cite and @b{Ref@TeX{}}. Bib-cite.el comes bundled with | |
3335 | AUCTeX. | |
3336 | ||
3337 | Bib-cite version 3.06 and later can be configured so that bib-cite's | |
3338 | mouse functions use @b{Ref@TeX{}} for displaying references and citations. | |
3339 | This can be useful in particular when working with the LaTeX @code{xr} | |

3381 | The label environment definitions in @code{reftex-label-alist} are | |
3382 | global and apply to all documents. If you need to make definitions | |
3383 | local to a document, because they would interfere with settings in other | |
3384 | documents, you should use AUCTeX and set up style files with calls to | |
3385 | @code{reftex-add-label-environments}, @code{reftex-set-cite-format}, | |
3386 | @code{reftex-add-index-macros}, and @code{reftex-add-section-levels}. | |

3398 | When using packages which make the buffer representation of a file | |
3399 | different from its disk representation (e.g. x-symbol, isotex, | |
3400 | iso-cvt) you may find that @b{Ref@TeX{}}'s parsing information sometimes | |
3401 | reflects the disk state of a file. This happens only in @emph{unvisited} | |
3402 | parts of a multifile document, because @b{Ref@TeX{}} visits these files | |
3403 | literally for speed reasons. Then both short context and section | |
3404 | headings may look different from what you usually see on your screen. | |
3405 | In rare cases @code{reftex-toc} may have problems to jump to an affected | |
3406 | section heading. There are three possible ways to deal with | |
3407 | this: | |
3408 | @itemize @minus | |

3410 | @vindex reftex-keep-temporary-buffers | |

3412 | This implies that @b{Ref@TeX{}} will load all parts of a multifile | |
3413 | document into Emacs (i.e. there won't be any temporary buffers). | |
3414 | @item | |
3415 | @vindex reftex-initialize-temporary-buffers | |
3416 | @code{(setq reftex-initialize-temporary-buffers t)}@* | |
3417 | This means full initialization of temporary buffers. It involves | |

3428 | @cindex @code{pf}, LaTeX package | |
3429 | @cindex LaTeX packages, @code{pf} | |
3430 | Some packages use an additional argument to a @code{\begin} macro | |
3431 | to specify a label. E.g. Lamport's @file{pf.sty} uses both | |
3432 | @example | |
3433 | \step@{@var{label}@}@{@var{claim}@} and \begin@{step+@}@{@var{label}@} | |
3434 | @var{claim} | |
3435 | \end@{step+@} | |
3436 | @end example | |
3437 | ||
3438 | @noindent | |
3439 | We need to trick @b{Ref@TeX{}} into swallowing this: | |
3440 | ||
3441 | @lisp | |
3442 | @group | |
3443 | ;; Configuration for Lamport's pf.sty | |
3444 | (setq reftex-label-alist | |
3445 | '(("\\step@{*@}@{@}" ?p "st:" "~\\stepref@{%s@}" 2 ("Step" "St.")) | |
3446 | ("\\begin@{step+@}@{*@}" ?p "st:" "~\\stepref@{%s@}" 1000))) | |
3447 | @end group | |
3448 | @end lisp | |
3449 | ||
3450 | @noindent | |
3451 | The first line is just a normal configuration for a macro. For the | |
3452 | @code{step+} environment we actually tell @b{Ref@TeX{}} to look for the | |
3453 | @emph{macro} @samp{\begin@{step+@}} and interpret the @emph{first} | |
3454 | argument (which really is a second argument to the macro @code{\begin}) | |
3455 | as a label of type @code{?p}. Argument count for this macro starts only | |
3456 | after the @samp{@{step+@}}, also when specifying how to get | |
3457 | context. | |

3463 | In XEmacs, idle timer restart does not work reliably after fast | |

3546 | @cindex Commands, list of | |
3547 | ||
3548 | Here is a summary of @b{Ref@TeX{}}'s commands which can be executed from | |
3549 | LaTeX files. Command which are executed from the special buffers are | |
3550 | not described here. All commands are available from the @code{Ref} | |
3551 | menu. See @xref{Key Bindings}. | |
3552 | ||
3553 | @deffn Command reftex-toc | |
3554 | Show the table of contents for the current document. When called with | |
3555 | one ore two @kbd{C-u} prefixes, rescan the document first. | |
3556 | @end deffn | |
3557 | ||
3558 | @deffn Command reftex-label | |
3559 | Insert a unique label. With one or two @kbd{C-u} prefixes, enforce | |
3560 | document rescan first. | |
3561 | @end deffn | |
3562 | ||
3563 | @deffn Command reftex-reference | |
3564 | Start a selection process to select a label, and insert a reference to | |
3565 | it. With one or two @kbd{C-u} prefixes, enforce document rescan first. | |
3566 | @end deffn | |
3567 | ||
3568 | @deffn Command reftex-citation | |
3569 | Make a citation using BibTeX database files. After prompting for a regular | |
3570 | expression, scans the buffers with BibTeX entries (taken from the | |
3571 | @code{\bibliography} command or a @code{thebibliography} environment) | |
3572 | and offers the matching entries for selection. The selected entry is | |
3573 | formatted according to @code{reftex-cite-format} and inserted into the | |
3574 | buffer. @* | |
3575 | When called with a @kbd{C-u} prefix, prompt for optional arguments in | |
3576 | cite macros. When called with a numeric prefix, make that many citations. | |
3577 | When called with point inside the braces of a @code{\cite} command, it | |
3578 | will add another key, ignoring the value of | |
3579 | @code{reftex-cite-format}. @* | |
3580 | The regular expression uses an expanded syntax: @samp{&&} is interpreted | |
3581 | as @code{and}. Thus, @samp{aaaa&&bbb} matches entries which contain | |
3582 | both @samp{aaaa} and @samp{bbb}. While entering the regexp, completion | |
3583 | on knows citation keys is possible. @samp{=} is a good regular | |
3584 | expression to match all entries in all files. | |
3585 | @end deffn | |
3586 | ||
3587 | @deffn Command reftex-index | |
3588 | Query for an index macro and insert it along with its arguments. The | |
3589 | index macros available are those defined in @code{reftex-index-macro} or | |
3590 | by a call to @code{reftex-add-index-macros}, typically from an AUCTeX | |
3591 | style file. @b{Ref@TeX{}} provides completion for the index tag and the | |
3592 | index key, and will prompt for other arguments. | |
3593 | @end deffn | |
3594 | ||
3595 | @deffn Command reftex-index-selection-or-word | |
3596 | Put current selection or the word near point into the default index | |
3597 | macro. This uses the information in @code{reftex-index-default-macro} | |
3598 | to make an index entry. The phrase indexed is the current selection or | |
3599 | the word near point. When called with one @kbd{C-u} prefix, let the | |
3600 | user have a chance to edit the index entry. When called with 2 | |
3601 | @kbd{C-u} as prefix, also ask for the index macro and other stuff. When | |
3602 | called inside TeX math mode as determined by the @file{texmathp.el} | |
3603 | library which is part of AUCTeX, the string is first processed with the | |
3604 | @code{reftex-index-math-format}, which see. | |
3605 | @end deffn | |
3606 | ||
3607 | @deffn Command reftex-index-phrase-selection-or-word | |
3608 | Add current selection or the word at point to the phrases buffer. | |
3609 | When you are in transient-mark-mode and the region is active, the | |
3610 | selection will be used - otherwise the word at point. | |
3611 | You get a chance to edit the entry in the phrases buffer - to save the | |
3612 | buffer and return to the LaTeX document, finish with @kbd{C-c C-c}. | |
3613 | @end deffn | |
3614 | ||
3615 | @deffn Command reftex-index-visit-phrases-buffer | |
3616 | Switch to the phrases buffer, initialize if empty. | |
3617 | @end deffn | |
3618 | ||
3619 | @deffn Command reftex-index-phrases-apply-to-region | |
3620 | Index all index phrases in the current region. | |
3621 | This works exactly like global indexing from the index phrases buffer, | |
3622 | but operation is restricted to the current region. | |
3623 | @end deffn | |
3624 | ||
3625 | @deffn Command reftex-display-index | |
3626 | Display a buffer with an index compiled from the current document. | |
3627 | When the document has multiple indices, first prompts for the correct one. | |
3628 | When index support is turned off, offer to turn it on. | |
3629 | With one or two @kbd{C-u} prefixes, rescan document first. | |
3630 | With prefix 2, restrict index to current document section. | |
3631 | With prefix 3, restrict index to active region. | |
3632 | @end deffn | |
3633 | ||
3634 | @deffn Command reftex-view-crossref | |
3635 | View cross reference of macro at point. Point must be on the @var{key} | |
3636 | argument. Works with the macros @code{\label}, @code{\ref}, | |
3637 | @code{\cite}, @code{\bibitem}, @code{\index} and many derivatives of | |
3638 | these. Where it makes sense, subsequent calls show additional | |
3639 | locations. See also the variable @code{reftex-view-crossref-extra} and | |
3640 | the command @code{reftex-view-crossref-from-bibtex}. With one or two | |
3641 | @kbd{C-u} prefixes, enforce rescanning of the document. With argument | |
3642 | 2, select the window showing the cross reference. | |
3643 | @end deffn | |
3644 | ||
3645 | @deffn Command reftex-view-crossref-from-bibtex | |
3646 | View location in a LaTeX document which cites the BibTeX entry at point. | |
3647 | Since BibTeX files can be used by many LaTeX documents, this function | |
3648 | prompts upon first use for a buffer in @b{Ref@TeX{}} mode. To reset this | |
3649 | link to a document, call the function with a prefix arg. Calling | |
3650 | this function several times find successive citation locations. | |
3651 | @end deffn | |
3652 | ||
3653 | @deffn Command reftex-create-tags-file | |
3654 | Create TAGS file by running @code{etags} on the current document. The | |
3655 | TAGS file is also immediately visited with | |
3656 | @code{visit-tags-table}. | |
3657 | @end deffn | |

3667 | Starts always in the master file. Stops when a match is found. | |
3668 | No active TAGS table is required. | |
3669 | @end deffn | |

3680 | sequence they appear in the document. | |
3681 | @end deffn | |
3682 | ||
3683 | @deffn Command reftex-goto-label | |
3684 | Prompt for a label (with completion) and jump to the location of this | |
3685 | label. Optional prefix argument @var{other-window} goes to the label in | |
3686 | another window. | |
3687 | @end deffn | |

3692 | @code{\ref} commands. Works on the entire multifile document. No | |
3693 | active TAGS table is required. | |

3696 | @deffn Command reftex-renumber-simple-labels | |
3697 | Renumber all simple labels in the document to make them sequentially. | |
3698 | Simple labels are the ones created by RefTeX, consisting only of the | |
3699 | prefix and a number. After the command completes, all these labels will | |
3700 | have sequential numbers throughout the document. Any references to the | |
3701 | labels will be changed as well. For this, @b{Ref@TeX{}} looks at the | |
3702 | arguments of any macros which either start or end with the string | |
3703 | @samp{ref}. This command should be used with care, in particular in | |
3704 | multifile documents. You should not use it if another document refers | |
3705 | to this one with the @code{xr} package. | |
3706 | @end deffn | |

3713 | Create a new BibTeX database file with all entries referenced in document. | |
3714 | The command prompts for a filename and writes the collected entries to | |
3715 | that file. Only entries referenced in the current document with | |
3716 | any @code{\cite}-like macros are used. | |
3717 | The sequence in the new file is the same as it was in the old database. | |

3781 | same as the positive value, but the section will never get a number. | |
3782 | The @code{cdr} may also be a function which then has to return the | |
3783 | level. This list is also used for promotion and demotion of sectioning | |
3784 | commands. If you are using a document class which has several sets of | |
3785 | sectioning commands, promotion only works correctly if this list is | |
3786 | sorted first by set, then within each set by level. The promotion | |
3787 | commands always select the nearest entry with the correct new level. | |
3788 | ||
3789 | @end defopt | |
3790 | ||
3791 | @defopt reftex-toc-max-level | |
3792 | The maximum level of toc entries which will be included in the TOC. | |
3793 | Section headings with a bigger level will be ignored. In RefTeX, | |
3794 | chapters are level 1, sections level 2 etc. This variable can be | |
3795 | changed from within the @file{*toc*} buffer with the @kbd{t} key. | |
3796 | @end defopt | |
3797 | ||
3798 | @defopt reftex-part-resets-chapter | |
3799 | Non-@code{nil} means, @code{\part} is like any other sectioning command. | |
3800 | This means, part numbers will be included in the numbering of chapters, and | |
3801 | chapter counters will be reset for each part. | |
3802 | When @code{nil} (the default), parts are special, do not reset the | |
3803 | chapter counter and also do not show up in chapter numbers. | |
3804 | @end defopt | |
3805 | ||
3806 | @defopt reftex-auto-recenter-toc | |
3807 | Non-@code{nil} means, turn automatic recentering of @file{*TOC*} window on. | |
3808 | When active, the @file{*TOC*} window will always show the section you | |
3809 | are currently working in. Recentering happens whenever Emacs is idle for | |
3810 | more than @code{reftex-idle-time} seconds. | |
3811 | ||
3812 | Value @code{t} means, turn on immediately when RefTeX gets started. Then, | |
3813 | recentering will work for any toc window created during the session. | |
3814 | ||
3815 | Value @code{frame} (the default) means, turn automatic recentering on | |
3816 | only while the dedicated TOC frame does exist, and do the recentering | |
3817 | only in that frame. So when creating that frame (with @kbd{d} key in an | |
3818 | ordinary TOC window), the automatic recentering is turned on. When the | |
3819 | frame gets destroyed, automatic recentering is turned off again. | |
3820 | ||
3821 | This feature can be turned on and off from the menu | |
3822 | (Ref->Options). | |
3823 | @end defopt | |

3832 | @end defopt | |
3833 | ||
3834 | @defopt reftex-toc-keep-other-windows | |
3835 | Non-@code{nil} means, split the selected window to display the | |
3836 | @file{*toc*} buffer. This helps to keep the window configuration, but | |
3837 | makes the @file{*toc*} small. When @code{nil}, all other windows except | |
3838 | the selected one will be deleted, so that the @file{*toc*} window fills | |
3839 | half the frame. | |
3840 | @end defopt | |

3870 | window will show the corresponding part of the document. This flag can | |

3890 | @defopt reftex-default-label-alist-entries | |
3891 | Default label alist specifications. It is a list of symbols with | |
3892 | associations in the constant @code{reftex-label-alist-builtin}. | |
3893 | @code{LaTeX} should always be the last entry. | |
3894 | @end defopt | |
3895 | ||
3896 | @defopt reftex-label-alist | |
3897 | Set this variable to define additions and changes to the defaults in | |
3898 | @code{reftex-default-label-alist-entries}. The only things you | |
3899 | @emph{must not} change is that @code{?s} is the type indicator for | |
3900 | section labels, and @key{SPC} for the @code{any} label type. These are | |
3901 | hard-coded at other places in the code. | |
3902 | ||
3903 | The value of the variable must be a list of items. Each item is a list | |
3904 | itself and has the following structure: | |
3905 | ||
3906 | @example | |
3907 | (@var{env-or-macro} @var{type-key} @var{label-prefix} @var{reference-format} | |
3908 | @var{context-method} (@var{magic-word} ... ) @var{toc-level}) | |
3909 | @end example | |
3910 | ||
3911 | Each list entry describes either an environment carrying a counter for | |
3912 | use with @code{\label} and @code{\ref}, or a LaTeX macro defining a | |
3913 | label as (or inside) one of its arguments. The elements of each list | |
3914 | entry are: | |
3915 | ||
3916 | @table @asis | |
3917 | @item @var{env-or-macro} | |
3918 | Name of the environment (like @samp{table}) or macro (like | |
3919 | @samp{\myfig}). For macros, indicate the arguments, as in | |
3920 | @samp{\myfig[]@{@}@{@}@{*@}@{@}}. Use square brackets for optional | |
3921 | arguments, a star to mark the label argument, if any. The macro does | |
3922 | not have to have a label argument - you could also use | |
3923 | @samp{\label@{...@}} inside one of its arguments. | |
3924 | ||
3925 | Special names: @code{section} for section labels, @code{any} to define a | |
3926 | group which contains all labels. | |
3927 | ||
3928 | This may also be a function to do local parsing and identify point to be | |
3929 | in a non-standard label environment. The function must take an | |
3930 | argument @var{bound} and limit backward searches to this value. It | |
3931 | should return either nil or a cons cell @code{(@var{function} | |
3932 | . @var{position})} with the function symbol and the position where the | |
3933 | special environment starts. See the Info documentation for an | |
3934 | example. | |
3935 | ||
3936 | Finally this may also be @code{nil} if the entry is only meant to change | |
3937 | some settings associated with the type indicator character (see | |
3938 | below). | |
3939 | ||
3940 | @item @var{type-key} | |
3941 | Type indicator character, like @code{?t}, must be a printable ASCII | |
3942 | character. The type indicator is a single character which defines a | |
3943 | label type. Any label inside the environment or macro is assumed to | |
3944 | belong to this type. The same character may occur several times in this | |
3945 | list, to cover cases in which different environments carry the same | |
3946 | label type (like @code{equation} and @code{eqnarray}). If the type | |
3947 | indicator is @code{nil} and the macro has a label argument @samp{@{*@}}, | |
3948 | the macro defines neutral labels just like @code{\label}. In this case | |
3949 | the reminder of this entry is ignored. | |
3950 | ||
3951 | @item @var{label-prefix} | |
3952 | Label prefix string, like @samp{tab:}. The prefix is a short string | |
3953 | used as the start of a label. It may be the empty string. The prefix | |
3954 | may contain the following @samp{%} escapes: | |
3955 | ||
3956 | @example | |
3957 | %f Current file name, directory and extension stripped. | |
3958 | %F Current file name relative to master file directory. | |
3959 | %m Master file name, directory and extension stripped. | |
3960 | %M Directory name (without path) where master file is located. | |
3961 | %u User login name, on systems which support this. | |
3962 | %S A section prefix derived with variable @code{reftex-section-prefixes}. | |
3963 | @end example | |
3964 | ||
3965 | @noindent | |
3966 | Example: In a file @file{intro.tex}, @samp{eq:%f:} will become | |
3967 | @samp{eq:intro:}. | |
3968 | ||
3969 | @item @var{reference-format} | |
3970 | Format string for reference insert in buffer. @samp{%s} will be | |
3971 | replaced by the label. When the format starts with @samp{~}, this | |
3972 | @samp{~} will only be inserted when the character before point is | |
3973 | @emph{not} a whitespace. | |
3974 | ||
3975 | @item @var{context-method} | |
3976 | Indication on how to find the short context. | |
3977 | @itemize @minus | |
3978 | @item | |
3979 | If @code{nil}, use the text following the @samp{\label@{...@}} macro. | |
3980 | @item | |
3981 | If @code{t}, use | |
3982 | @itemize @minus | |
3983 | @item | |
3984 | the section heading for section labels. | |
3985 | @item | |
3986 | text following the @samp{\begin@{...@}} statement of environments (not | |
3987 | a good choice for environments like eqnarray or enumerate, where one has | |
3988 | several labels in a single environment). | |
3989 | @item | |
3990 | text after the macro name (starting with the first arg) for | |
3991 | macros. | |
3992 | @end itemize | |
3993 | @item | |
3994 | If an integer, use the nth argument of the macro. As a special case, | |
3995 | 1000 means to get text after the last macro argument. | |
3996 | @item | |
3997 | If a string, use as regexp to search @emph{backward} from the label. | |
3998 | Context is then the text following the end of the match. E.g. putting | |
3999 | this to @samp{\\caption[[@{]} will use the caption in a figure or table | |
4000 | environment. @samp{\\begin@{eqnarray@}\|\\\\} works for | |
4001 | eqnarrays. | |
4002 | @item | |
4003 | If any of @code{caption}, @code{item}, @code{eqnarray-like}, | |
4004 | @code{alignat-like}, this symbol will internally be translated into an | |
4005 | appropriate regexp (see also the variable | |
4006 | @code{reftex-default-context-regexps}). | |
4007 | @item | |
4008 | If a function, call this function with the name of the environment/macro | |
4009 | as argument. On call, point will be just after the @code{\label} macro. | |
4010 | The function is expected to return a suitable context string. It should | |
4011 | throw an exception (error) when failing to find context. As an example, | |
4012 | here is a function returning the 10 chars following the label macro as | |
4013 | context: | |
4014 | ||
4015 | @example | |
4016 | (defun my-context-function (env-or-mac) | |
4017 | (if (> (point-max) (+ 10 (point))) | |
4018 | (buffer-substring (point) (+ 10 (point))) | |
4019 | (error "Buffer too small"))) | |
4020 | @end example | |
4021 | @end itemize | |
4022 | ||
4023 | Label context is used in two ways by @b{Ref@TeX{}}: For display in the label | |
4024 | menu, and to derive a label string. If you want to use a different | |
4025 | method for each of these, specify them as a dotted pair. | |
4026 | E.g. @code{(nil . t)} uses the text after the label (@code{nil}) for | |
4027 | display, and text from the default position (@code{t}) to derive a label | |
4028 | string. This is actually used for section labels. | |
4029 | ||
4030 | @item @var{magic-word-list} | |
4031 | List of magic words which identify a reference to be of this type. If | |
4032 | the word before point is equal to one of these words when calling | |
4033 | @code{reftex-reference}, the label list offered will be automatically | |
4034 | restricted to labels of the correct type. If the first element of this | |
4035 | word--list is the symbol `regexp', the strings are interpreted as regular | |
4036 | expressions. | |
4037 | ||
4038 | @item @var{toc-level} | |
4039 | The integer level at which this environment should be added to the table | |
4040 | of contents. See also @code{reftex-section-levels}. A positive value | |
4041 | will number the entries mixed with the sectioning commands of the same | |
4042 | level. A negative value will make unnumbered entries. Useful only for | |
4043 | theorem-like environments which structure the document. Will be ignored | |
4044 | for macros. When omitted or @code{nil}, no TOC entries will be | |
4045 | made. | |
4046 | @end table | |
4047 | ||
4048 | If the type indicator characters of two or more entries are the same, | |
4049 | @b{Ref@TeX{}} will use | |
4050 | @itemize @minus | |
4051 | @item | |
4052 | the first non-@code{nil} format and prefix | |
4053 | @item | |
4054 | the magic words of all involved entries. | |
4055 | @end itemize | |
4056 | ||
4057 | Any list entry may also be a symbol. If that has an association in | |
4058 | @code{reftex-label-alist-builtin}, the @code{cddr} of that association is | |
4059 | spliced into the list. However, builtin defaults should normally be set | |
4060 | with the variable @code{reftex-default-label-alist-entries}. | |
4061 | @end defopt | |
4062 | ||
4063 | @defopt reftex-section-prefixes | |
4064 | Prefixes for section labels. When the label prefix given in an entry in | |
4065 | @code{reftex-label-alist} contains @samp{%S}, this list is used to | |
4066 | determine the correct prefix string depending on the current section | |
4067 | level. The list is an alist, with each entry of the form | |
4068 | @w{@code{(@var{key} . @var{prefix})}}. Possible keys are sectioning macro | |
4069 | names like @samp{chapter}, integer section levels (as given in | |
4070 | @code{reftex-section-levels}), and @code{t} for the default. | |
4071 | @end defopt | |
4072 | ||
4073 | @defopt reftex-default-context-regexps | |
4074 | Alist with default regular expressions for finding context. The emacs | |
4075 | lisp form @w{@code{(format regexp (regexp-quote environment))}} is used | |
4076 | to calculate the final regular expression - so @samp{%s} will be | |
4077 | replaced with the environment or macro. | |
4078 | @end defopt | |
4079 | ||
4080 | @defopt reftex-trust-label-prefix | |
4081 | Non-@code{nil} means, trust the label prefix when determining label type. | |
4082 | It is customary to use special label prefixes to distinguish different label | |
4083 | types. The label prefixes have no syntactic meaning in LaTeX (unless | |
4084 | special packages like fancyref) are being used. RefTeX can and by | |
4085 | default does parse around each label to detect the correct label type, | |
4086 | but this process can be slow when a document contains thousands of | |
4087 | labels. If you use label prefixes consistently, you may speed up | |
4088 | document parsing by setting this variable to a non-nil value. RefTeX | |
4089 | will then compare the label prefix with the prefixes found in | |
4090 | `reftex-label-alist' and derive the correct label type in this way. | |
4091 | Possible values for this option are: | |
4092 | ||
4093 | @example | |
4094 | t @r{This means to trust any label prefixes found.} | |
4095 | regexp @r{If a regexp, only prefixes matched by the regexp are trusted.} | |
4096 | list @r{List of accepted prefixes, as strings. The colon is part of} | |
4097 | @r{the prefix, e.g. ("fn:" "eqn:" "item:").} | |
4098 | nil @r{Never trust a label prefix.} | |
4099 | @end example | |
4100 | The only disadvantage of using this feature is that the label context | |
4101 | displayed in the label selection buffer along with each label is | |
4102 | simply some text after the label definition. This is no problem if you | |
4103 | place labels keeping this in mind (e.g. @i{before} the equation, @i{at | |
4104 | the beginning} of a fig/tab caption ...). Anyway, it is probably best | |
4105 | to use the regexp or the list value types to fine-tune this feature. | |
4106 | For example, if your document contains thousands of footnotes with | |
4107 | labels fn:xxx, you may want to set this variable to the value "^fn:$" or | |
4108 | ("fn:"). Then RefTeX will still do extensive parsing for any | |
4109 | non-footnote labels. | |

4117 | @defopt reftex-insert-label-flags | |
4118 | Flags governing label insertion. The value has the form | |
4119 | ||
4120 | @example | |
4121 | (@var{derive} @var{prompt}) | |
4122 | @end example | |
4123 | ||
4124 | If @var{derive}is @code{t}, @b{Ref@TeX{}} will try to derive a sensible | |
4125 | label from context. A section label for example will be derived from | |
4126 | the section heading. The conversion of the context to a valid label is | |
4127 | governed by the specifications given in | |
4128 | @code{reftex-derive-label-parameters}. If @var{derive} is @code{nil}, | |
4129 | the default label will consist of the prefix and a unique number, like | |
4130 | @samp{eq:23}. | |
4131 | ||
4132 | If @var{prompt} is @code{t}, the user will be prompted for a label | |
4133 | string. When @var{prompt} is @code{nil}, the default label will be | |
4134 | inserted without query. | |
4135 | ||
4136 | So the combination of @var{derive} and @var{prompt} controls label | |
4137 | insertion. Here is a table describing all four possibilities: | |
4138 | ||
4139 | @example | |
4140 | @group | |
4141 | @var{derive} @var{prompt} @var{action} | |
4142 | ----------------------------------------------------------- | |
4143 | nil nil @r{Insert simple label, like @samp{eq:22} or @samp{sec:13}. No query.} | |
4144 | nil t @r{Prompt for label.} | |
4145 | t nil @r{Derive a label from context and insert. No query.} | |
4146 | t t @r{Derive a label from context, prompt for confirmation.} | |
4147 | @end group | |
4148 | @end example | |
4149 | ||
4150 | Each flag may be set to @code{t}, @code{nil}, or a string of label type | |
4151 | letters indicating the label types for which it should be true. Thus, | |
4152 | the combination may be set differently for each label type. The default | |
4153 | settings @samp{"s"} and @samp{"sft"} mean: Derive section labels from | |
4154 | headings (with confirmation). Prompt for figure and table labels. Use | |
4155 | simple labels without confirmation for everything else. | |
4156 | ||
4157 | The available label types are: @code{s} (section), @code{f} (figure), | |
4158 | @code{t} (table), @code{i} (item), @code{e} (equation), @code{n} | |
4159 | (footnote), @code{N} (endnote) plus any definitions in | |

4163 | @deffn Hook reftex-format-label-function | |

4166 | arguments, the @var{label} and the @var{default-format} (usually | |

4233 | @defopt reftex-label-menu-flags | |
4234 | List of flags governing the label menu makeup. The flags are: | |
4235 | @table @asis | |
4236 | @item @var{table-of-contents} | |
4237 | Show the labels embedded in a table of context. | |
4238 | @item @var{section-numbers} | |
4239 | Include section numbers (like 4.1.3) in table of contents. | |
4240 | @item @var{counters} | |
4241 | Show counters. This just numbers the labels in the menu. | |
4242 | @item @var{no-context} | |
4243 | Non-@code{nil} means do @emph{not} show the short context. | |
4244 | @item @var{follow} | |
4245 | Follow full context in other window. | |
4246 | @item @var{show-commented} | |
4247 | Show labels from regions which are commented out. | |
4248 | @item @var{match-everywhere} | |
4249 | Obsolete flag. | |
4250 | @item @var{show-files} | |
4251 | Show begin and end of included files. | |
4252 | @end table | |
4253 | ||
4254 | Each of these flags can be set to @code{t} or @code{nil}, or to a string | |
4255 | of type letters indicating the label types for which it should be true. | |
4256 | These strings work like character classes in regular expressions. Thus, | |
4257 | setting one of the flags to @samp{"sf"} makes the flag true for section | |
4258 | and figure labels, @code{nil} for everything else. Setting it to | |
4259 | @samp{"^sf"} makes it the other way round. | |
4260 | ||
4261 | The available label types are: @code{s} (section), @code{f} (figure), | |
4262 | @code{t} (table), @code{i} (item), @code{e} (equation), @code{n} | |
4263 | (footnote), plus any definitions in @code{reftex-label-alist}. | |
4264 | ||
4265 | Most options can also be switched from the label menu itself - so if you | |
4266 | decide here to not have a table of contents in the label menu, you can | |
4267 | still get one interactively during selection from the label menu. | |
4268 | @end defopt | |
4269 | ||
4270 | @defopt reftex-multiref-punctuation | |
4271 | Punctuation strings for multiple references. When marking is used in | |
4272 | the selection buffer to select several references, this variable | |
4273 | associates the 3 marking characters @samp{,-+} with prefix strings to be | |
4274 | inserted into the buffer before the corresponding @code{\ref} macro. | |
4275 | This is used to string together whole reference sets, like | |
4276 | @samp{eqs. 1,2,3-5,6 and 7} in a single call to | |
4277 | @code{reftex-reference}. | |
4278 | @end defopt | |
4279 | ||
4280 | @defopt reftex-vref-is-default | |
4281 | Non-@code{nil} means, the varioref macro @code{\vref} is used as | |
4282 | default. In the selection buffer, the @kbd{v} key toggles the reference | |
4283 | macro between @code{\ref} and @code{\vref}. The value of this variable | |
4284 | determines the default which is active when entering the selection | |
4285 | process. Instead of @code{nil} or @code{t}, this may also be a string | |
4286 | of type letters indicating the label types for which it should be | |
4287 | true. | |
4288 | @end defopt | |
4289 | ||
4290 | @defopt reftex-fref-is-default | |
4291 | Non-@code{nil} means, the fancyref macro @code{\fref} is used as | |
4292 | default. In the selection buffer, the @kbd{V} key toggles the reference | |
4293 | macro between @code{\ref}, @code{\fref} and @code{\Fref}. The value of | |
4294 | this variable determines the default which is active when entering the | |
4295 | selection process. Instead of @code{nil} or @code{t}, this may also be | |
4296 | a string of type letters indicating the label types for which it should | |
4297 | be true. | |
4298 | @end defopt | |

4300 | @deffn Hook reftex-format-ref-function | |
4301 | If non-@code{nil}, should be a function which produces the string to | |
4302 | insert as a reference. Note that the insertion format can also be | |
4303 | changed with @code{reftex-label-alist}. This hook also is used by the | |
4304 | special commands to insert @code{\vref} and @code{\fref} references, so | |
4305 | even if you set this, your setting will be ignored by the special | |
4306 | commands. The function will be called with two arguments, the | |
4307 | @var{label} and the @var{default-format} (usually @samp{~\ref@{%s@}}). | |
4308 | It should return the string to insert into the buffer. | |

4315 | @defopt reftex-guess-label-type | |
4316 | Non-@code{nil} means, @code{reftex-reference} will try to guess the | |
4317 | label type. To do that, @b{Ref@TeX{}} will look at the word before the | |
4318 | cursor and compare it with the magic words given in | |
4319 | @code{reftex-label-alist}. When it finds a match, @b{Ref@TeX{}} will | |
4320 | immediately offer the correct label menu - otherwise it will prompt you | |
4321 | for a label type. If you set this variable to @code{nil}, @b{Ref@TeX{}} | |
4322 | will always prompt for a label type. | |

4384 | @defopt reftex-cite-format | |
4385 | The format of citations to be inserted into the buffer. It can be a | |
4386 | string, an alist or a symbol. In the simplest case this is just the string | |
4387 | @samp{\cite@{%l@}}, which is also the default. See the definition of | |
4388 | @code{reftex-cite-format-builtin} for more complex examples. | |
4389 | ||
4390 | If @code{reftex-cite-format} is a string, it will be used as the format. | |
4391 | In the format, the following percent escapes will be expanded. | |
4392 | ||
4393 | @table @code | |
4394 | @item %l | |
4395 | The BibTeX label of the citation. | |
4396 | @item %a | |
4397 | List of author names, see also @code{reftex-cite-punctuation}. | |
4398 | @item %2a | |
4399 | Like %a, but abbreviate more than 2 authors like Jones et al. | |
4400 | @item %A | |
4401 | First author name only. | |
4402 | @item %e | |
4403 | Works like @samp{%a}, but on list of editor names. (@samp{%2e} and | |
4404 | @samp{%E} work a well). | |
4405 | @end table | |
4406 | ||
4407 | It is also possible to access all other BibTeX database fields: | |
4408 | ||
4409 | @example | |
4410 | %b booktitle %c chapter %d edition %h howpublished | |
4411 | %i institution %j journal %k key %m month | |
4412 | %n number %o organization %p pages %P first page | |
4413 | %r address %s school %u publisher %t title | |
4414 | %v volume %y year | |
4415 | %B booktitle, abbreviated %T title, abbreviated | |
4416 | @end example | |
4417 | ||
4418 | @noindent | |
4419 | Usually, only @samp{%l} is needed. The other stuff is mainly for the | |
4420 | echo area display, and for @code{(setq reftex-comment-citations t)}. | |
4421 | ||
4422 | @samp{%<} as a special operator kills punctuation and space around it | |
4423 | after the string has been formatted. | |
4424 | ||
4425 | A pair of square brackets indicates an optional argument, and RefTeX | |
4426 | will prompt for the values of these arguments. | |
4427 | ||
4428 | Beware that all this only works with BibTeX database files. When | |
4429 | citations are made from the @code{\bibitems} in an explicit | |
4430 | @code{thebibliography} environment, only @samp{%l} is available. | |
4431 | ||
4432 | If @code{reftex-cite-format} is an alist of characters and strings, the | |
4433 | user will be prompted for a character to select one of the possible | |
4434 | format strings. | |
4435 | ||
4436 | In order to configure this variable, you can either set | |
4437 | @code{reftex-cite-format} directly yourself or set it to the | |
4438 | @emph{symbol} of one of the predefined styles. The predefined symbols | |
4439 | are those which have an association in the constant | |
4440 | @code{reftex-cite-format-builtin}) E.g.: @code{(setq reftex-cite-format | |
4441 | 'natbib)}. | |
4442 | @end defopt | |
4443 | ||
4444 | @deffn Hook reftex-format-cite-function | |
4445 | If non-@code{nil}, should be a function which produces the string to | |
4446 | insert as a citation. Note that the citation format can also be changed | |
4447 | with the variable @code{reftex-cite-format}. The function will be | |
4448 | called with two arguments, the @var{citation-key} and the | |
4449 | @var{default-format} (taken from @code{reftex-cite-format}). It should | |
4450 | return the string to insert into the buffer. | |

4452 | ||
4453 | @defopt reftex-cite-prompt-optional-args | |

4455 | When an entry in @code{reftex-cite-format} ist given with square brackets to | |
4456 | indicate optional arguments (for example @samp{\\cite[][]@{%l@}}), RefTeX can | |
4457 | prompt for values. Possible values are: | |
4458 | @example | |
4459 | nil @r{Never prompt for optional arguments} | |
4460 | t @r{Always prompt} | |
4461 | maybe @r{Prompt only if @code{reftex-citation} was called with C-u prefix arg}@end example | |
4462 | Unnecessary empty optional arguments are removed before insertion into | |
4463 | the buffer. See @code{reftex-cite-cleanup-optional-args}. | |
4464 | @end defopt | |
4465 | ||

4514 | is resource intensive and the internal structure holding the parsed | |
4515 | information can become quite big. Therefore it can be turned off. When | |

4525 | @end defopt | |
4526 | ||
4527 | @defopt reftex-index-macros | |
4528 | List of macros which define index entries. The structure of each entry | |
4529 | is | |
4530 | @lisp | |
4531 | (@var{macro} @var{index-tag} @var{key} @var{prefix} @var{exclude} @var{repeat}) | |
4532 | @end lisp | |
4533 | ||
4534 | @var{macro} is the macro. Arguments should be denoted by empty braces, | |
4535 | as for example in @samp{\index[]@{*@}}. Use square brackets to denote | |
4536 | optional arguments. The star marks where the index key is. | |
4537 | ||
4538 | @var{index-tag} is a short name of the index. @samp{idx} and @samp{glo} | |
4539 | are reserved for the default index and the glossary. Other indices can | |
4540 | be defined as well. If this is an integer, the Nth argument of the | |
4541 | macro holds the index tag. | |
4542 | ||
4543 | @var{key} is a character which is used to identify the macro for input | |
4544 | with @code{reftex-index}. @samp{?i}, @samp{?I}, and @samp{?g} are | |
4545 | reserved for default index and glossary. | |
4546 | ||
4547 | @var{prefix} can be a prefix which is added to the @var{key} part of the | |
4548 | index entry. If you have a macro | |
4549 | @code{\newcommand@{\molec@}[1]@{#1\index@{Molecules!#1@}}, this prefix | |
4550 | should be @samp{Molecules!}. | |
4551 | ||
4552 | @var{exclude} can be a function. If this function exists and returns a | |
4553 | non-@code{nil} value, the index entry at point is ignored. This was | |
4554 | implemented to support the (deprecated) @samp{^} and @samp{_} shortcuts | |
4555 | in the LaTeX2e @code{index} package. | |
4556 | ||
4557 | @var{repeat}, if non-@code{nil}, means the index macro does not typeset | |
4558 | the entry in the text, so that the text has to be repeated outside the | |
4559 | index macro. Needed for @code{reftex-index-selection-or-word} and for | |
4560 | indexing from the phrase buffer. | |
4561 | ||
4562 | The final entry may also be a symbol. It must have an association in | |
4563 | the variable @code{reftex-index-macros-builtin} to specify the main | |
4564 | indexing package you are using. Valid values are currently | |
4565 | @example | |
4566 | default @r{The LaTeX default - unnecessary to specify this one} | |
4567 | multind @r{The multind.sty package} | |
4568 | index @r{The index.sty package} | |
4569 | index-shortcut @r{The index.sty packages with the ^ and _ shortcuts.} | |
4570 | @r{Should not be used - only for old documents} | |
4571 | @end example | |
4572 | Note that AUCTeX sets these things internally for @b{Ref@TeX{}} as well, | |
4573 | so with a sufficiently new version of AUCTeX, you should not set the | |
4574 | package here. | |
4575 | @end defopt | |
4576 | ||
4577 | @defopt reftex-index-default-macro | |
4578 | The default index macro for @code{reftex-index-selection-or-word}. | |
4579 | This is a list with @code{(@var{macro-key} @var{default-tag})}. | |
4580 | ||
4581 | @var{macro-key} is a character identifying an index macro - see | |
4582 | @code{reftex-index-macros}. | |
4583 | ||
4584 | @var{default-tag} is the tag to be used if the macro requires a | |
4585 | @var{tag} argument. When this is @code{nil} and a @var{tag} is needed, | |
4586 | @b{Ref@TeX{}} will ask for it. When this is the empty string and the | |
4587 | TAG argument of the index macro is optional, the TAG argument will be | |
4588 | omitted. | |

4591 | @defopt reftex-index-default-tag | |
4592 | Default index tag. When working with multiple indexes, RefTeX queries | |
4593 | for an index tag when creating index entries or displaying a specific | |
4594 | index. This variable controls the default offered for these queries. | |
4595 | The default can be selected with @key{RET} during selection or | |
4596 | completion. Valid values of this variable are: | |
4597 | @example | |
4598 | nil @r{Do not provide a default index} | |
4599 | "tag" @r{The default index tag given as a string, e.g. "idx"} | |
4600 | last @r{The last used index tag will be offered as default} | |

4604 | @defopt reftex-index-math-format | |
4605 | Format of index entries when copied from inside math mode. When | |
4606 | @code{reftex-index-selection-or-word} is executed inside TeX math mode, | |
4607 | the index key copied from the buffer is processed with this format | |
4608 | string through the @code{format} function. This can be used to add the | |
4609 | math delimiters (e.g. @samp{$}) to the string. Requires the | |
4610 | @file{texmathp.el} library which is part of AUCTeX. | |
4611 | @end defopt | |
4612 | ||
4613 | @defopt reftex-index-phrase-file-extension | |

4616 | @end defopt | |
4617 | ||
4618 | @defopt reftex-index-phrases-logical-and-regexp | |
4619 | Regexp matching the @samp{and} operator for index arguments in phrases | |
4620 | file. When several index arguments in a phrase line are separated by | |
4621 | this operator, each part will generate an index macro. So each match of | |
4622 | the search phrase will produce @emph{several} different index entries. | |
4623 | Make sure this does no match things which are not separators. This | |
4624 | logical @samp{and} has higher priority than the logical @samp{or} | |
4625 | specified in @code{reftex-index-phrases-logical-or-regexp}. | |
4626 | @end defopt | |
4627 | ||
4628 | @defopt reftex-index-phrases-logical-or-regexp | |
4629 | Regexp matching the @samp{or} operator for index arguments in phrases | |
4630 | file. When several index arguments in a phrase line are separated by | |
4631 | this operator, the user will be asked to select one of them at each | |
4632 | match of the search phrase. The first index arg will be the default. A | |
4633 | number key @kbd{1}--@kbd{9} must be pressed to switch to another. Make | |
4634 | sure this does no match things which are not separators. The logical | |
4635 | @samp{and} specified in @code{reftex-index-phrases-logical-or-regexp} | |

4637 | @end defopt | |
4638 | ||
4639 | @defopt reftex-index-phrases-search-whole-words | |
4640 | Non-@code{nil} means phrases search will look for whole words, not subwords. | |
4641 | This works by requiring word boundaries at the beginning and end of | |
4642 | the search string. When the search phrase already has a non-word-char | |
4643 | at one of these points, no word boundary is required there. | |
4644 | @end defopt | |

4650 | ||
4651 | @defopt reftex-index-verify-function | |
4652 | A function which is called at each match during global indexing. | |

4654 | @end defopt | |
4655 | ||
4656 | @defopt reftex-index-phrases-skip-indexed-matches | |
4657 | Non-@code{nil} means, skip matches which appear to be indexed already. | |
4658 | When doing global indexing from the phrases buffer, searches for some | |
4659 | phrases may match at places where that phrase was already indexed. In | |
4660 | particular when indexing an already processed document again, this | |
4661 | will even be the norm. When this variable is non-@code{nil}, | |
4662 | @b{Ref@TeX{}} checks if the match is an index macro argument, or if an | |
4663 | index macro is directly before or after the phrase. If that is the | |
4664 | case, that match will be ignored. | |
4665 | @end defopt | |
4666 | ||
4667 | @defopt reftex-index-phrases-wrap-long-lines | |
4668 | Non-@code{nil} means, when indexing from the phrases buffer, wrap lines. | |
4669 | Inserting indexing commands in a line makes the line longer - often | |
4670 | so long that it does not fit onto the screen. When this variable is | |
4671 | non-@code{nil}, newlines will be added as necessary before and/or after the | |
4672 | indexing command to keep lines short. However, the matched text | |
4673 | phrase and its index command will always end up on a single line. | |
4674 | @end defopt | |

4676 | @defopt reftex-index-phrases-sort-prefers-entry | |
4677 | Non-@code{nil} means when sorting phrase lines, the explicit index entry | |
4678 | is used. Phrase lines in the phrases buffer contain a search phrase, and | |
4679 | sorting is normally based on these. Some phrase lines also have | |
4680 | an explicit index argument specified. When this variable is | |
4681 | non-@code{nil}, the index argument will be used for sorting. | |
4682 | @end defopt | |
4683 | ||
4684 | @defopt reftex-index-phrases-sort-in-blocks | |
4685 | Non-@code{nil} means, empty and comment lines separate phrase buffer | |
4686 | into blocks. Sorting will then preserve blocks, so that lines are | |
4687 | re-arranged only within blocks. | |

4700 | The letters which denote sections in the index. Usually these are all | |
4701 | capital letters. Don't use any downcase letters. Order is not | |
4702 | significant, the index will be sorted by whatever the sort function | |
4703 | thinks is correct. In addition to these letters, @b{Ref@TeX{}} will | |
4704 | create a group @samp{!} which contains all entries sorted below the | |
4705 | lowest specified letter. In the @file{*Index*} buffer, pressing any of | |
4706 | these capital letters or @kbd{!} will jump to that section. | |

4733 | Macros which can be used for the display of cross references. | |
4734 | This is used when `reftex-view-crossref' is called with point in an | |
4735 | argument of a macro. Note that crossref viewing for citations, | |
4736 | references (both ways) and index entries is hard-coded. This variable | |
4737 | is only to configure additional structures for which crossreference | |
4738 | viewing can be useful. Each entry has the structure | |
4739 | @example | |
4740 | (@var{macro-re} @var{search-re} @var{highlight}). | |
4741 | @end example | |
4742 | @var{macro-re} is matched against the macro. @var{search-re} is the | |
4743 | regexp used to search for cross references. @samp{%s} in this regexp is | |
4744 | replaced with the macro argument at point. @var{highlight} is an | |
4745 | integer indicating which subgroup of the match should be highlighted. | |

4748 | @defopt reftex-auto-view-crossref | |
4749 | Non-@code{nil} means, initially turn automatic viewing of crossref info | |
4750 | on. Automatic viewing of crossref info normally uses the echo area. | |
4751 | Whenever point is idle for more than @code{reftex-idle-time} seconds on | |
4752 | the argument of a @code{\ref} or @code{\cite} macro, and no other | |
4753 | message is being displayed, the echo area will display information about | |
4754 | that cross reference. You can also set the variable to the symbol | |
4755 | @code{window}. In this case a small temporary window is used for the | |

4830 | Association list with file extensions for different file types. | |
4831 | This is a list of items, each item is like: | |
4832 | @code{(@var{type} . (@var{def-ext} @var{other-ext} ...))} | |

4842 | @defopt reftex-search-unrecursed-path-first | |
4843 | Non-@code{nil} means, search all specified directories before trying | |
4844 | recursion. Thus, in a path @samp{.//:/tex/}, search first @samp{./}, | |
4845 | then @samp{/tex/}, and then all subdirectories of @samp{./}. If this | |
4846 | option is @code{nil}, the subdirectories of @samp{./} are searched | |
4847 | before @samp{/tex/}. This is mainly for speed - most of the time the | |
4848 | recursive path is for the system files and not for the user files. Set | |
4849 | this to @code{nil} if the default makes @b{Ref@TeX{}} finding files with | |

4856 | @code{TEXINPUTS} and @code{BIBINPUTS} to find TeX files and BibTeX | |
4857 | database files. With this option turned on, it calls an external | |

4907 | potentially slow but will happen only once). If a buffer is to be thrown | |

4933 | or the file associated with the label or section heading near point in a | |
4934 | menu. Requesting re-parsing of an entire multifile document then | |

4992 | Font-lock must be loaded as well to actually get fontified | |
4993 | display. After changing this option, a rescan may be necessary to | |
4994 | activate it. | |
4995 | @end defopt | |
4996 | ||
4997 | @defopt reftex-refontify-context | |
4998 | Non-@code{nil} means, re-fontify the context in the label menu with | |
4999 | font-lock. This slightly slows down the creation of the label menu. It | |
5000 | is only necessary when you definitely want the context fontified. | |
5001 | ||
5002 | This option may have 3 different values: | |
5003 | @table @code | |
5004 | @item nil | |
5005 | Never refontify. | |
5006 | @item t | |
5007 | Always refontify. | |

5015 | @defopt reftex-highlight-selection | |
5016 | Non-@code{nil} means, highlight selected text in selection and | |
5017 | @file{*toc*} buffers. Normally, the text near the cursor is the | |
5018 | @emph{selected} text, and it is highlighted. This is the entry most | |
5019 | keys in the selection and @file{*toc*} buffers act on. However, if you | |
5020 | mainly use the mouse to select an item, you may find it nice to have | |
5021 | mouse-triggered highlighting @emph{instead} or @emph{as well}. The | |
5022 | variable may have one of these values: | |
5023 | ||
5024 | @example | |
5025 | nil @r{No highlighting.} | |
5026 | cursor @r{Highlighting is cursor driven.} | |
5027 | mouse @r{Highlighting is mouse driven.} | |
5028 | both @r{Both cursor and mouse trigger highlighting.} | |
5029 | @end example | |
5030 | ||
5031 | Changing this variable requires to rebuild the selection and *toc* | |
5032 | buffers to become effective (keys @kbd{g} or @kbd{r}). | |

5164 | @noindent @b{Version 4.26} | |
5165 | @itemize @bullet | |
5166 | @item | |
5167 | Support for global incremental search. | |

5173 | @itemize @bullet | |
5174 | @item | |
5175 | Fixed bug with @samp{%F} in a label prefix. Added new escapes | |

5178 | ||
5179 | @noindent @b{Version 4.24} | |
5180 | @itemize @bullet | |
5181 | @item | |
5182 | Inserting citation commands now prompts for optional arguments | |

5184 | @code{reftex-cite-prompt-optional-args} and | |
5185 | @code{reftex-cite-cleanup-optional-args}. | |
5186 | @item | |
5187 | New option @code{reftex-trust-label-prefix}. Configure this variable | |
5188 | if you'd like RefTeX to base its classification of labels on prefixes. | |

5238 | @code{reftex-auto-recenter-toc} is turned on. | |
5239 | @item | |
