461 | This doc string is easier to understand after reading the configuration |
462 | examples in the manual. Looking at the builtin defaults in the constant | |
1a9461d0 CD |
463 | `reftex-label-alist-builtin' may also be instructive. |
464 | ||
465 | Set this variable to define additions and changes to the default. The only | |
466 | things you MUST NOT change is that `?s' is the type indicator for section | |
467 | labels, and SPC for the `any' label type. These are hard-coded at other | |
468 | places in the code. | |
469 | ||
470 | The value of the variable must be a list of items. Each item is a list | |
471 | itself and has the following structure: | |
472 | ||
473 | (ENV-OR-MACRO TYPE-KEY LABEL-PREFIX REFERENCE-FORMAT CONTEXT-METHOD | |
7c4d13cc | 474 | (MAGIC-WORD ... ) TOC-LEVEL) |
1a9461d0 CD |
475 | |
476 | Each list entry describes either an environment carrying a counter for use | |
477 | with \\label and \\ref, or a LaTeX macro defining a label as (or inside) | |
478 | one of its arguments. The elements of each list entry are: | |
479 | ||
480 | ENV-OR-MACRO | |
481 | Name of the environment (like \"table\") or macro (like \"\\\\myfig\"). | |
482 | For macros, indicate the macro arguments for best results, as in | |
483 | \"\\\\myfig[]{}{}{*}{}\". Use square brackets for optional arguments, | |
484 | a star to mark the label argument, if any. The macro does not have to | |
485 | have a label argument - you could also use \\label{..} inside one of | |
486 | its arguments. | |
487 | Special names: `section' for section labels, `any' to define a group | |
488 | which contains all labels. | |
489 | ||
4f595e15 RA |
490 | This may also be a function to do local parsing and identify point to |
491 | be in a non-standard label environment. The function must take an | |
492 | argument BOUND and limit backward searches to this value. It should | |
493 | return either nil or the position where the special environment starts. | |
494 | See the Info documentation for an example. | |
1a9461d0 CD |
495 | |
496 | Finally this may also be nil if the entry is only meant to change | |
497 | some settings associated with the type indicator character (see below). | |
498 | ||
499 | TYPE-KEY | |
500 | Type indicator character, like `?t', must be a printable ASCII character. | |
501 | The type indicator is a single character which defines a label type. | |
502 | Any label inside the environment or macro is assumed to belong to this | |
503 | type. The same character may occur several times in this list, to cover | |
504 | cases in which different environments carry the same label type (like | |
505 | `equation' and `eqnarray'). | |
506 | If the type indicator is nil and the macro has a label argument {*}, | |
70d797cd | 507 | the macro defines neutral labels just like \\label. In this case |
4f595e15 | 508 | the remainder of this entry is ignored. |
1a9461d0 CD |
509 | |
510 | LABEL-PREFIX | |
511 | Label prefix string, like \"tab:\". | |
512 | The prefix is a short string used as the start of a label. It may be the | |
513 | empty string. The prefix may contain the following `%' escapes: | |
514 | %f Current file name with directory and extension stripped. | |
515 | %F Current file name relative to directory of master file. | |
f3c18bd0 CD |
516 | %m Master file name, directory and extension stripped. |
517 | %M Directory name (without path) where master file is located. | |
1a9461d0 CD |
518 | %u User login name, on systems which support this. |
519 | %S A section prefix derived with variable `reftex-section-prefixes'. | |
520 | ||
521 | Example: In a file `intro.tex', \"eq:%f:\" will become \"eq:intro:\"). | |
522 | ||
523 | REFERENCE-FORMAT | |
4f595e15 RA |
524 | Format string for reference insertion in buffer. `%s' will be replaced |
525 | by the label. | |
1a9461d0 CD |
526 | When the format starts with `~', the `~' will only be inserted if |
527 | there is not already a whitespace before point. | |
528 | ||
529 | CONTEXT-METHOD | |
530 | Indication on how to find the short context. | |
531 | - If nil, use the text following the \\label{...} macro. | |
532 | - If t, use | |
533 | - the section heading for section labels. | |
534 | - text following the \\begin{...} statement of environments. | |
535 | (not a good choice for environments like eqnarray or enumerate, | |
536 | where one has several labels in a single environment). | |
537 | - text after the macro name (starting with the first arg) for macros. | |
538 | - If an integer, use the nth argument of the macro. As a special case, | |
539 | 1000 means to get text after the last macro argument. | |
540 | - If a string, use as regexp to search *backward* from the label. Context | |
4f595e15 | 541 | is then the text following the end of the match. E.g. setting this to |
1a9461d0 CD |
542 | \"\\\\\\\\caption[[{]\" will use the caption in a figure or table |
543 | environment. | |
544 | \"\\\\\\\\begin{eqnarray}\\\\|\\\\\\\\\\\\\\\\\" works for eqnarrays. | |
545 | - If any of `caption', `item', `eqnarray-like', `alignat-like', this | |
546 | symbol will internally be translated into an appropriate regexp | |
547 | (see also the variable `reftex-default-context-regexps'). | |
548 | - If a function, call this function with the name of the environment/macro | |
549 | as argument. On call, point will be just after the \\label macro. The | |
550 | function is expected to return a suitable context string. It should | |
551 | throw an exception (error) when failing to find context. | |
552 | As an example, here is a function returning the 10 chars following | |
553 | the label macro as context: | |
554 | ||
555 | (defun my-context-function (env-or-mac) | |
556 | (if (> (point-max) (+ 10 (point))) | |
557 | (buffer-substring (point) (+ 10 (point))) | |
558 | (error \"Buffer too small\"))) | |
559 | ||
560 | Label context is used in two ways by RefTeX: For display in the label | |
561 | menu, and to derive a label string. If you want to use a different | |
562 | method for each of these, specify them as a dotted pair. | |
563 | E.g. `(nil . t)' uses the text after the label (nil) for display, and | |
564 | text from the default position (t) to derive a label string. This is | |
565 | actually used for section labels. | |
566 | ||
567 | MAGIC-WORDS | |
568 | List of magic words which identify a reference to be of this type. | |
569 | If the word before point is equal to one of these words when calling | |
570 | `reftex-reference', the label list offered will be automatically | |
571 | restricted to labels of the correct type. | |
572 | If the first element of this wordlist is the symbol `regexp', the | |
573 | strings are interpreted as regular expressions. RefTeX will add | |
574 | a \"\\\\W\" to the beginning and other stuff to the end of the regexp. | |
575 | ||
7c4d13cc CD |
576 | TOC-LEVEL |
577 | The integer level at which this environment should be added to the | |
578 | table of contents. See also `reftex-section-levels'. A positive | |
579 | value will number the entries mixed with the sectioning commands of | |
580 | the same level. A negative value will make unnumbered entries. | |
581 | Useful only for theorem-like environments, will be ignored for macros. | |
582 | When omitted or nil, no TOC entries will be made. | |
583 | ||
1a9461d0 CD |
584 | If the type indicator characters of two or more entries are the same, RefTeX |
585 | will use | |
586 | - the first non-nil format and prefix | |
587 | - the magic words of all involved entries. | |
588 | ||
589 | Any list entry may also be a symbol. If that has an association in | |
590 | `reftex-label-alist-builtin', the cddr of that association is spliced into the | |
591 | list. However, builtin defaults should normally be set with the variable | |
983741d8 | 592 | `reftex-default-label-alist-entries'." |

668 | It is customary to use special label prefixes to distinguish different label | |
669 | types. The label prefixes have no syntactic meaning in LaTeX (unless | |
3a1e8128 | 670 | special packages like fancyref are being used). RefTeX can and by |
f3c18bd0 CD |
671 | default does parse around each label to detect the correct label type, |
672 | but this process can be slow when a document contains thousands of | |
673 | labels. If you use label prefixes consistently, you may speed up | |
674 | document parsing by setting this variable to a non-nil value. RefTeX | |
675 | will then compare the label prefix with the prefixes found in | |
676 | `reftex-label-alist' and derive the correct label type in this way. | |
677 | Possible values for this option are: | |
678 | ||
679 | t This means to trust any label prefixes found. | |
680 | regexp If a regexp, only prefixes matched by the regexp are trusted. | |
681 | list List of accepted prefixes, as strings. The colon is part of | |
682 | the prefix, e.g. (\"fn:\" \"eqn:\" \"item:\"). | |
683 | nil Never trust a label prefix. | |
684 | ||
685 | The only disadvantage of using this feature is that the label context | |
686 | displayed in the label selection buffer along with each label is | |
687 | simply some text after the label definition. This is no problem if you | |
688 | place labels keeping this in mind (e.g. *before* the equation, *at | |
689 | the beginning* of a fig/tab caption ...). Anyway, it is probably best | |
690 | to use the regexp or the list value types to fine-tune this feature. | |
691 | For example, if your document contains thousands of footnotes with | |
692 | labels fn:xxx, you may want to set this variable to the value \"^fn:$\" or | |

705 | These are special functions to detect \"environments\" which do not | |
706 | start with \\begin and end with \\end. Some LaTeX packages seem to | |
707 | use such non-standard ways to set up environment-like constructs. The | |
708 | purpose of each function in this list is to detect if point is | |
709 | currently inside such a special \"environment\". If the environment | |
710 | carries a label, you must also set up an entry for it in | |
711 | `reftex-label-alist'. | |
712 | ||
713 | The function should check if point is currently in the special | |
714 | environment it was written to detect. If so, the function must return | |
715 | a cons cell (NAME . POSITION). NAME is the name of the environment | |
716 | detected and POSITION is the buffer position where the environment | |
717 | starts. The function must return nil on failure to detect the | |
718 | environment. | |
719 | ||
720 | The function must take an argument BOUND. If non-nil, BOUND is a | |
721 | boundary for backwards searches which should be observed. | |
722 | ||
723 | Here is an example. The LaTeX package linguex.sty defines list macros | |
724 | `\\ex.', `\\a.', etc for lists which are terminated by `\\z.' or an empty | |
725 | line. | |
726 | ||
727 | \\ex. \\label{ex:12} Some text in an exotic language ... | |

729 | \\b. \\label{ex:14} still more stuff | |
730 | ||
731 | ... more text after the empty line terminating all lists | |
732 | ||
733 | And here is the setup for RefTeX: | |
734 | ||
735 | 1. Define a dummy environment for this in `reftex-label-alist'. Dummy means, | |
736 | make up an environment name even though it is not used with \\begin and | |
737 | \\end. Here we use \"linguex\" as this name. | |

742 | 2. Write a function to detect the list macros and the determinators as well. | |

774 | "Flags governing label insertion. First flag DERIVE, second flag PROMPT. | |
775 | ||
776 | If DERIVE is t, RefTeX will try to derive a sensible label from context. | |
777 | A section label for example will be derived from the section heading. | |
f8b00e0f | 778 | The conversion of the context to a valid label is governed by the |
1a9461d0 CD |
779 | specifications given in `reftex-derive-label-parameters'. |
780 | If RefTeX fails to derive a label, it will prompt the user. | |
781 | If DERIVE is nil, the label generated will consist of the prefix and a | |
782 | unique number, like `eq:23'. | |
783 | ||
784 | If PROMPT is t, the user will be prompted for a label string. The prompt will | |
785 | already contain the prefix, and (if DERIVE is t) a default label derived from | |
786 | context. When PROMPT is nil, the default label will be inserted without | |
787 | query. | |
788 | ||
789 | So the combination of DERIVE and PROMPT controls label insertion. Here is a | |
790 | table describing all four possibilities: | |
791 | ||
792 | DERIVE PROMPT ACTION | |
793 | ------------------------------------------------------------------------- | |
794 | nil nil Insert simple label, like eq:22 or sec:13. No query. | |
795 | nil t Prompt for label. | |
796 | t nil Derive a label from context and insert without query. | |
797 | t t Derive a label from context and prompt for confirmation. | |
798 | ||
799 | Each flag may be set to t, nil, or a string of label type letters | |
800 | indicating the label types for which it should be true. The strings work | |
801 | like character classes. | |
802 | Thus, the combination may be set differently for each label type. The | |
803 | default settings \"s\" and \"sft\" mean: Derive section labels from headings | |
3666daf6 | 804 | \(with confirmation). Prompt for figure and table labels. Use simple labels |
1a9461d0 CD |
805 | without confirmation for everything else. |

1363 | INDEX-TAG is a short name of the index. \"idx\" and \"glo\" are | |
1364 | reserved for the default index and the glossary. Other indices can be | |
1365 | defined as well. If this is an integer, the Nth argument of the macro | |
1366 | holds the index tag. | |
1367 | ||
1368 | KEY is a character which is used to identify the macro for input with | |
1369 | \\[reftex-index]. ?i, ?I, and ?g are reserved for default index and glossary. | |
1370 | ||
1371 | PREFIX can be a prefix which is added to the KEY part of the index entry. | |
1372 | If you have a macro \\newcommand{\\molec}[1]{#1\\index{Molecules!#1}}, this | |
1373 | prefix should be \"Molecules!\". See the manual for details. | |
1374 | ||
1375 | EXCLUDE can be a function. If this function exists and returns a non-nil | |
1376 | value, the index entry at point is ignored. This was implemented to support | |
1377 | the (deprecated) `^' and `_' shortcuts in the LaTeX2e `index' package. | |
