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

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

702 These are special functions to detect \"environments\" which do not
703 start with \\begin and end with \\end. Some LaTeX packages seem to
704 use such non-standard ways to set up environment-like constructs. The
705 purpose of each function in this list is to detect if point is
706 currently inside such a special \"environment\". If the environment
707 carries a label, you must also set up an entry for it in
708 `reftex-label-alist'.
710 The function should check if point is currently in the special
711 environment it was written to detect. If so, the function must return
712 a cons cell (NAME . POSITION). NAME is the name of the environment
713 detected and POSITION is the buffer position where the environment
714 starts. The function must return nil on failure to detect the
715 environment.
717 The function must take an argument BOUND. If non-nil, BOUND is a
718 boundary for backwards searches which should be observed.
720 Here is an example. The LaTeX package linguex.sty defines list macros
721 `\\ex.', `\\a.', etc for lists which are terminated by `\\z.' or an empty
722 line.
724 \\ex. \\label{ex:12} Some text in an exotic language ...
725 \\a. \\label{ex:13} more stuff
726 \\b. \\label{ex:14} still more stuff
728 ... more text after the empty line terminating all lists
730 And here is the setup for RefTeX:
732 1. Define a dummy environment for this in `reftex-label-alist'. Dummy means,
733 make up an environment name even though it is not used with \\begin and
734 \\end. Here we use \"linguex\" as this name.
736 (setq reftex-label-alist
737 '((\"linguex\" ?x \"ex:\" \"~\\\\ref{%s}\" nil (\"Example\" \"Ex.\"))))
739 2. Write a function to detect the list macros and the determinators as well.
741 (defun my-detect-linguex-list (bound)
742 (let ((pos (point)) p1)
743 (save-excursion

751 ;; Return nil because list was already closed
753 ;; OK, we got it

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

1360 INDEX-TAG is a short name of the index. \"idx\" and \"glo\" are
1361 reserved for the default index and the glossary. Other indices can be
1362 defined as well. If this is an integer, the Nth argument of the macro
1363 holds the index tag.
1365 KEY is a character which is used to identify the macro for input with
1366 \\[reftex-index]. ?i, ?I, and ?g are reserved for default index and glossary.
1368 PREFIX can be a prefix which is added to the KEY part of the index entry.
1369 If you have a macro \\newcommand{\\molec}[1]{#1\\index{Molecules!#1}}, this
1370 prefix should be \"Molecules!\". See the manual for details.
1372 EXCLUDE can be a function. If this function exists and returns a non-nil
1373 value, the index entry at point is ignored. This was implemented to support
