447 This docstring is easier to understand after reading the configuration
448 examples in `reftex.el'. Looking at the builtin defaults in the constant
449 `reftex-label-alist-builtin' may also be instructive.
451 Set this variable to define additions and changes to the default. The only
452 things you MUST NOT change is that `?s' is the type indicator for section
453 labels, and SPC for the `any' label type. These are hard-coded at other
454 places in the code.
456 The value of the variable must be a list of items. Each item is a list
457 itself and has the following structure:
459 (ENV-OR-MACRO TYPE-KEY LABEL-PREFIX REFERENCE-FORMAT CONTEXT-METHOD
460 (MAGIC-WORD ... ) TOC-LEVEL)
462 Each list entry describes either an environment carrying a counter for use
463 with \\label and \\ref, or a LaTeX macro defining a label as (or inside)
464 one of its arguments. The elements of each list entry are:
466 ENV-OR-MACRO
467 Name of the environment (like \"table\") or macro (like \"\\\\myfig\").
468 For macros, indicate the macro arguments for best results, as in
469 \"\\\\myfig[]{}{}{*}{}\". Use square brackets for optional arguments,
470 a star to mark the label argument, if any. The macro does not have to
471 have a label argument - you could also use \\label{..} inside one of
472 its arguments.
473 Special names: `section' for section labels, `any' to define a group
474 which contains all labels.
476 This may also be a function to do local parsing and identify point
477 to be in a non-standard label environment. The function must take
478 an argument BOUND and limit backward searches to this value. It
479 should return either nil or a cons cell (FUNCTION . POSITION) with
480 the function symbol and the position where the special environment
481 starts. See the Info documentation for an example.
483 Finally this may also be nil if the entry is only meant to change
484 some settings associated with the type indicator character (see below).
486 TYPE-KEY
487 Type indicator character, like `?t', must be a printable ASCII character.
488 The type indicator is a single character which defines a label type.
489 Any label inside the environment or macro is assumed to belong to this
490 type. The same character may occur several times in this list, to cover
491 cases in which different environments carry the same label type (like
492 `equation' and `eqnarray').
493 If the type indicator is nil and the macro has a label argument {*},
494 the macro defines neutral labels just like \\label. In this case
495 the reminder of this entry is ignored.
497 LABEL-PREFIX
498 Label prefix string, like \"tab:\".
499 The prefix is a short string used as the start of a label. It may be the
500 empty string. The prefix may contain the following `%' escapes:
501 %f Current file name with directory and extension stripped.
502 %F Current file name relative to directory of master file.
503 %m Master file name, directory and extension stripped.
504 %M Directory name (without path) where master file is located.
505 %u User login name, on systems which support this.
506 %S A section prefix derived with variable `reftex-section-prefixes'.
508 Example: In a file `intro.tex', \"eq:%f:\" will become \"eq:intro:\").
510 REFERENCE-FORMAT
511 Format string for reference insert in buffer. `%s' will be replaced by
512 the label.
513 When the format starts with `~', the `~' will only be inserted if
514 there is not already a whitespace before point.
516 CONTEXT-METHOD
517 Indication on how to find the short context.
518 - If nil, use the text following the \\label{...} macro.
519 - If t, use
520 - the section heading for section labels.
521 - text following the \\begin{...} statement of environments.
522 (not a good choice for environments like eqnarray or enumerate,
523 where one has several labels in a single environment).
524 - text after the macro name (starting with the first arg) for macros.
525 - If an integer, use the nth argument of the macro. As a special case,
526 1000 means to get text after the last macro argument.
527 - If a string, use as regexp to search *backward* from the label. Context
528 is then the text following the end of the match. E.g. putting this to
529 \"\\\\\\\\caption[[{]\" will use the caption in a figure or table
530 environment.
531 \"\\\\\\\\begin{eqnarray}\\\\|\\\\\\\\\\\\\\\\\" works for eqnarrays.
532 - If any of `caption', `item', `eqnarray-like', `alignat-like', this
533 symbol will internally be translated into an appropriate regexp
534 (see also the variable `reftex-default-context-regexps').
535 - If a function, call this function with the name of the environment/macro
536 as argument. On call, point will be just after the \\label macro. The
537 function is expected to return a suitable context string. It should
538 throw an exception (error) when failing to find context.
539 As an example, here is a function returning the 10 chars following
540 the label macro as context:

547 Label context is used in two ways by RefTeX: For display in the label
548 menu, and to derive a label string. If you want to use a different
549 method for each of these, specify them as a dotted pair.
550 E.g. `(nil . t)' uses the text after the label (nil) for display, and
551 text from the default position (t) to derive a label string. This is
552 actually used for section labels.
554 MAGIC-WORDS
555 List of magic words which identify a reference to be of this type.
556 If the word before point is equal to one of these words when calling
557 `reftex-reference', the label list offered will be automatically
558 restricted to labels of the correct type.
559 If the first element of this wordlist is the symbol `regexp', the
560 strings are interpreted as regular expressions. RefTeX will add
561 a \"\\\\W\" to the beginning and other stuff to the end of the regexp.
563 TOC-LEVEL
564 The integer level at which this environment should be added to the
565 table of contents. See also `reftex-section-levels'. A positive
566 value will number the entries mixed with the sectioning commands of
567 the same level. A negative value will make unnumbered entries.
568 Useful only for theorem-like environments, will be ignored for macros.
569 When omitted or nil, no TOC entries will be made.
571 If the type indicator characters of two or more entries are the same, RefTeX
572 will use
573 - the first non-nil format and prefix
574 - the magic words of all involved entries.
576 Any list entry may also be a symbol. If that has an association in
577 `reftex-label-alist-builtin', the cddr of that association is spliced into the
578 list. However, builtin defaults should normally be set with the variable
579 `reftex-default-label-alist-entries."

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

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

733 (save-excursion

743 ;; OK, we got it

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

1049 %a List of author names, see also `reftex-cite-punctuation'.
1050 %2a Like %a, but abbreviate more than 2 authors like Jones et al.
1051 %A First author name only.
1052 %e Works like %a, but on list of editor names. (%2e and %E work a well)
1054 It is also possible to access all other BibTeX database fields:
1055 %b booktitle %c chapter %d edition %h howpublished
1056 %i institution %j journal %k key %m month
1057 %n number %o organization %p pages %P first page
1058 %r address %s school %u publisher %t title
1059 %v volume %y year
1060 %B booktitle, abbreviated %T title, abbreviated
1062 Usually, only %l is needed. The other stuff is mainly for the echo area
1063 display, and for (setq reftex-comment-citations t).
1065 %< as a special operator kills punctuation and space around it after the
1066 string has been formatted.
1068 A pair of square brackets indicates an optional argument, and RefTeX
1069 will prompt for the values of these arguments.
1071 Beware that all this only works with BibTeX database files. When
1072 citations are made from the \\bibitems in an explicit thebibliography
1073 environment, only %l is available.
1075 If `reftex-cite-format' is an alist of characters and strings, the user
1076 will be prompted for a character to select one of the possible format
1077 strings.
1078 In order to configure this variable, you can either set

1223 reserved for the default index and the glossary. Other indices can be

1225 holds the index tag.
1227 KEY is a character which is used to identify the macro for input with
1228 \\[reftex-index]. ?i, ?I, and ?g are reserved for default index and glossary.
1230 PREFIX can be a prefix which is added to the KEY part of the index entry.
1231 If you have a macro \\newcommand{\\molec}[1]{#1\\index{Molecules!#1}}, this
1232 prefix should be \"Molecules!\". See the manual for details.
1234 EXCLUDE can be a function. If this function exists and returns a non-nil

1236 the (deprecated) `^' and `_' shortcuts in the LaTeX2e `index' package.
