"Alist with information on environments for \\label-\\ref use.
This doc string is easier to understand after reading the configuration
examples in the manual. Looking at the builtin defaults in the constant
`reftex-label-alist-builtin' may also be instructive.
Set this variable to define additions and changes to the default. The only
things you MUST NOT change is that `?s' is the type indicator for section
labels, and SPC for the `any' label type. These are hard-coded at other
places in the code.
The value of the variable must be a list of items. Each item is a list
itself and has the following structure:
(ENV-OR-MACRO TYPE-KEY LABEL-PREFIX REFERENCE-FORMAT CONTEXT-METHOD
(MAGIC-WORD ... ) TOC-LEVEL)
Each list entry describes either an environment carrying a counter for use
with \\label and \\ref, or a LaTeX macro defining a label as (or inside)
one of its arguments. The elements of each list entry are:
ENV-OR-MACRO
Name of the environment (like \"table\") or macro (like \"\\\\myfig\").
For macros, indicate the macro arguments for best results, as in
\"\\\\myfig[]{}{}{*}{}\". Use square brackets for optional arguments,
a star to mark the label argument, if any. The macro does not have to
have a label argument - you could also use \\label{..} inside one of
its arguments.
Special names: `section' for section labels, `any' to define a group
which contains all labels.
This may also be a function to do local parsing and identify point to
be in a non-standard label environment. The function must take an
argument BOUND and limit backward searches to this value. It should
return either nil or the position where the special environment starts.
See the Info documentation for an example.
Finally this may also be nil if the entry is only meant to change
some settings associated with the type indicator character (see below).
TYPE-KEY
Type indicator character, like `?t', must be a printable ASCII character.
The type indicator is a single character which defines a label type.
Any label inside the environment or macro is assumed to belong to this
type. The same character may occur several times in this list, to cover
cases in which different environments carry the same label type (like
`equation' and `eqnarray').
If the type indicator is nil and the macro has a label argument {*},
the macro defines neutral labels just like \\label. In this case
the remainder of this entry is ignored.
LABEL-PREFIX
Label prefix string, like \"tab:\".
The prefix is a short string used as the start of a label. It may be the
empty string. The prefix may contain the following `%' escapes:
%f Current file name with directory and extension stripped.
%F Current file name relative to directory of master file.
%m Master file name, directory and extension stripped.
%M Directory name (without path) where master file is located.
%u User login name, on systems which support this.
%S A section prefix derived with variable `reftex-section-prefixes'.
Example: In a file `intro.tex', \"eq:%f:\" will become \"eq:intro:\").
REFERENCE-FORMAT
Format string for reference insertion in buffer. `%s' will be replaced
by the label.
When the format starts with `~', the `~' will only be inserted if
there is not already a whitespace before point.
CONTEXT-METHOD
Indication on how to find the short context.
- If nil, use the text following the \\label{...} macro.
- If t, use
- the section heading for section labels.
- text following the \\begin{...} statement of environments.
(not a good choice for environments like eqnarray or enumerate,
where one has several labels in a single environment).
- text after the macro name (starting with the first arg) for macros.
- If an integer, use the nth argument of the macro. As a special case,
1000 means to get text after the last macro argument.
- If a string, use as regexp to search *backward* from the label. Context
is then the text following the end of the match. E.g. setting this to
\"\\\\\\\\caption[[{]\" will use the caption in a figure or table
environment.
\"\\\\\\\\begin{eqnarray}\\\\|\\\\\\\\\\\\\\\\\" works for eqnarrays.
- If any of `caption', `item', `eqnarray-like', `alignat-like', this
symbol will internally be translated into an appropriate regexp
(see also the variable `reftex-default-context-regexps').
- If a function, call this function with the name of the environment/macro
as argument. On call, point will be just after the \\label macro. The
function is expected to return a suitable context string. It should
throw an exception (error) when failing to find context.
As an example, here is a function returning the 10 chars following
the label macro as context:
(defun my-context-function (env-or-mac)
(if (> (point-max) (+ 10 (point)))
(buffer-substring (point) (+ 10 (point)))
(error \"Buffer too small\")))
Label context is used in two ways by RefTeX: For display in the label
menu, and to derive a label string. If you want to use a different
method for each of these, specify them as a dotted pair.
E.g. `(nil . t)' uses the text after the label (nil) for display, and
text from the default position (t) to derive a label string. This is
actually used for section labels.
MAGIC-WORDS
List of magic words which identify a reference to be of this type.
If the word before point is equal to one of these words when calling
`reftex-reference', the label list offered will be automatically
restricted to labels of the correct type.
If the first element of this wordlist is the symbol `regexp', the
strings are interpreted as regular expressions. RefTeX will add
a \"\\\\W\" to the beginning and other stuff to the end of the regexp.
TOC-LEVEL
The integer level at which this environment should be added to the
table of contents. See also `reftex-section-levels'. A positive
value will number the entries mixed with the sectioning commands of
the same level. A negative value will make unnumbered entries.
Useful only for theorem-like environments, will be ignored for macros.
When omitted or nil, no TOC entries will be made.
If the type indicator characters of two or more entries are the same, RefTeX
will use
- the first non-nil format and prefix
- the magic words of all involved entries.
Any list entry may also be a symbol. If that has an association in
`reftex-label-alist-builtin', the cddr of that association is spliced into the
list. However, builtin defaults should normally be set with the variable
`reftex-default-label-alist-entries'."

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

"List of functions to be called when trying to figure out current environment.
These are special functions to detect \"environments\" which do not
start with \\begin and end with \\end. Some LaTeX packages seem to
use such non-standard ways to set up environment-like constructs. The
purpose of each function in this list is to detect if point is
currently inside such a special \"environment\". If the environment
carries a label, you must also set up an entry for it in
`reftex-label-alist'.
The function should check if point is currently in the special
environment it was written to detect. If so, the function must return
a cons cell (NAME . POSITION). NAME is the name of the environment
detected and POSITION is the buffer position where the environment
starts. The function must return nil on failure to detect the
environment.
The function must take an argument BOUND. If non-nil, BOUND is a
boundary for backwards searches which should be observed.
Here is an example. The LaTeX package linguex.sty defines list macros
`\\ex.', `\\a.', etc for lists which are terminated by `\\z.' or an
empty line.
\\ex. \\label{ex:12} Some text in an exotic language ...
\\a. \\label{ex:13} more stuff
\\b. \\label{ex:14} still more stuff
... more text after the empty line terminating all lists
And here is the setup for RefTeX:
1. Define a dummy environment for this in `reftex-label-alist'. Dummy means,
make up an environment name even though it is not used with \\begin and
\\end. Here we use \"linguex\" as this name.
(setq reftex-label-alist
\\='((\"linguex\" ?x \"ex:\" \"~\\\\ref{%s}\" nil (\"Example\" \"Ex.\"))))
2. Write a function to detect the list macros and the determinators as well.
(defun my-detect-linguex-list (bound)
(let ((pos (point)) p1)
(save-excursion
;; Search for any of the linguex item macros at the beginning of a line
(if (re-search-backward
(concat \"^[ \\t]*\\\\(\\\\\\\\\\\\(ex\\\\|a\\\\|\"
\"b\\\\|c\\\\|d\\\\|e\\\\|f\\\\)g?\\\\.\\\\)\")
bound t)
(progn
(setq p1 (match-beginning 1))
;; Make sure no empty line or \\z. is between us and item macro
(if (re-search-forward \"\\n[ \\t]*\\n\\\\|\\\\\\\\z\\\\.\" pos t)
;; Return nil because list was already closed
nil
;; OK, we got it
(cons \"linguex\" p1)))
;; Return nil for not found

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

INDEX-TAG is a short name of the index. \"idx\" and \"glo\" are
reserved for the default index and the glossary. Other indices can be
defined as well. If this is an integer, the Nth argument of the macro
holds the index tag.
KEY is a character which is used to identify the macro for input with
\\[reftex-index]. ?i, ?I, and ?g are reserved for default index and glossary.
PREFIX can be a prefix which is added to the KEY part of the index entry.
If you have a macro \\newcommand{\\molec}[1]{#1\\index{Molecules!#1}}, this
prefix should be \"Molecules!\". See the manual for details.
EXCLUDE can be a function. If this function exists and returns a non-nil
value, the index entry at point is ignored. This was implemented to support
the (deprecated) `^' and `_' shortcuts in the LaTeX2e `index' package.
REPEAT, if non-nil, means the index macro does not typeset the entry in

- supply arguments for macros like `\\ref'. (flag 3)

You may also set the variable itself to t or nil in order to turn all
plug-ins on or off, respectively.
\\<LaTeX-mode-map>Supplying labels in new sections and environments applies when creating
sections with \\[LaTeX-section] and environments with \\[LaTeX-environment].
Supplying macro arguments applies when you insert such a macro interactively
with \\[TeX-insert-macro].
See the AUCTeX documentation for more information.
RefTeX uses `fset' to take over the function calls. Changing the variable
may require a restart of Emacs in order to become effective."
