|
||
;;; Commentary:
|
||
;;
|
||
;; RefTeX is a minor mode with distinct support for \ref, \label and
|
||
;; \cite commands in (multi-file) LaTeX documents.
|
||
;; Labels are created semi-automatically. Definition context of labels is
|
||
;; provided when creating a reference. Citations are simplified with
|
||
;; efficient database lookup. A table of contents buffer provides easy
|
||
;; access to any part of a document.
|
||
;;
|
||
;;
|
||
;; To turn RefTeX Minor Mode on and off in a particular buffer, use
|
||
;; `M-x reftex-mode'.
|
||
;;
|
||
;; To turn on RefTeX Minor Mode for all LaTeX files, add one of the
|
||
;; following lines to your .emacs file:
|
||
;;
|
||
;; (add-hook 'LaTeX-mode-hook 'turn-on-reftex) ; with AUCTeX LaTeX mode
|
||
;; (add-hook 'latex-mode-hook 'turn-on-reftex) ; with Emacs latex mode
|
||
;;
|
||
;;
|
||
;; DOCUMENTATION
|
||
;; -------------
|
||
;;
|
||
;; There is an extensive texinfo document describing RefTeX in detail.
|
||
;; When you are getting reftex.el with the Emacs distribution, the
|
||
;; info files should already be installed. To view this
|
||
;; documentation, use `M-x reftex-info RET'.
|
||
;;
|
||
;; The documentation is also available at
|
||
;;
|
||
;; http://www.strw.leidenuniv.nl/~dominik/Tools/

|

;;---------------------------------------------------------------------------
|
||
;;
|
||
;; RefTeX in a Nutshell
|
||
;; ====================
|
||
;;
|
||
;; 1. Labels and References
|
||
;; RefTeX distinguishes labels for different environments. It always
|
||
;; knows if a certain label references a figure, table etc.. You can
|
||
;; configure RefTeX to recognize any additional labeled environments
|
||
;; you have defined yourself (variable REFTEX-LABEL-ALIST).
|
||
;; - Creating Labels
|
||
;; Type `C-c (' (`reftex-label') to insert a label at point.
|
||
;; RefTeX will either
|
||
;; - derive a label from context (default for section labels)
|
||
;;
|
||
;; - insert a simple label consisting of a prefix and a number
|
||
;; (default for equations, enumerate items, and footnotes)
|
||
;; or
|
||
;;
|
||
;; - prompt for a label string (figures and tables).
|
||
;;
|
||
;; Which labels are created how is configurable (variable
|
||
;; REFTEX-INSERT-LABEL-FLAGS).
|
||
;;
|
||
;; - Referencing Labels
|
||
;; Referencing labels is a snap and I promise you'll love it.
|
||
;; In order to make a reference, type `C-c )'
|
||
;; (`reftex-reference'). This shows an outline of the document
|
||
;; with all labels of a certain type (figure, equation,...) and
|
||
;; context of the label definition. Selecting one of the labels
|
||
;; inserts a `\ref' macro into the original buffer. Online help
|
||
;; during the selection is available with `?'.
|
||
;;
|
||
;; 2. Citations
|
||
;; After typing `C-c [' (`reftex-citation'), RefTeX will let you
|
||
;; specify a regular expression to search in current BibTeX database
|
||
;; files (as specified in the `\bibliography' command) and pull out a
|
||
;; formatted list of matches for you to choose from. The list is
|
||
;; *formatted* and sorted, thus much easier to read than the raw
|
||
;; database entries. The text inserted into the buffer is by default
|
||
;; just `\cite{KEY}', but can also contain author names and the year
|
||
;; in a configurable way (variable REFTEX-CITE-FORMAT).
|
||
;;
|
||
;; 3. Viewing Cross References
|
||
;; With point on or anywhere before a `\ref' or `\cite' macro, press
|
||
;; `C-c &' (`reftex-view-crossref'). This will display the
|
||
;; corresponding label definition or BibTeX database entry in another
|
||
;; window.
|
||
;;
|
||
;; 4. Table of Contents
|
||
;; Typing `C-c =' (`reftex-toc') will show a table of contents of the
|
||
;; document. From that buffer, you can jump quickly to every part of
|
||
;; your document.
|
||
;;
|
||
;; 5. Multifile Documents
|
||
;; Multifile Domuments are fully supported. RefTeX will provide cross
|
||
;; referencing information from all files which are part of the
|
||
;; document. You may also use it to reference labels in external
|
||
;; documents (in cooperation with the LaTeX package `xr').
|
||
;;
|
||
;; 6. Document Parsing
|
||
;; RefTeX needs to parse the document in order to find labels and
|
||
;; other information. It will do it automatically once, when you
|
||
;; start working with a document. Re-parsing should not be necessary
|
||
;; too often since RefTeX updates its lists internally when you make
|
||
;; a new label with `reftex-label'. To enforce reparsing, call any
|
||
;; of the commands described above with a raw `C-u' prefix, or press
|
||
;; the `r' key in the label selection buffer or the table of contents
|
||
;; buffer.

|
||
This docstring is easier to understand after reading the configuration
|
||
examples in `reftex.el'. 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.
|
||
|
||
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:
|
||
|
||
0. 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 nil if the entry is only meant to change some settings
|
||
associated with the type indicator character (see below).
|
||
|
||
1. 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').
|
||
|
||
2. 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.
|
||
%u User login name, on systems which support this.
|
||
|
||
Example: In a file `intro.tex', \"eq:%f:\" will become \"eq:intro:\").
|
||
|
||
3. Format string for reference insert 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.
|
||
|
||
4. 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. putting 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.
|
||
|
||
Setting the variable `reftex-use-text-after-label-as-context' to t
|
||
overrides the setting here.
|
||
|
||
5. 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.
|
||
|
||
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."

"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 legal 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.
