;;; Commentary:
|
||
;;
|
||
;; RefTeX is a minor mode with distinct support for \ref, \label, \cite,
|
||
;; and \index commands in (multi-file) LaTeX documents.
|
||
;; - A table of contents provides easy access to any part of a document.
|
||
;; - Labels are created semi-automatically.
|
||
;; - Definition context of labels is provided when creating a reference.
|
||
;; - Citations are simplified with efficient database lookup.
|
||
;; - Text phrases can be collected in a file, for later global indexing.
|
||
;; - The index preview buffer helps to check and edit index entries.
|
||
;;
|
||
;;
|
||
;; INSTALLATION
|
||
;; ------------
|
||
;;
|
||
;; - If this file is part of an X/Emacs distribution, it is installed.
|
||
;; - For XEmacs 21.x, you need to install the RefTeX plug-in package
|
||
;; available from the XEmacs distribution sites.
|
||
;; - If you have downloaded this file from the maintainers webpage, follow
|
||
;; the instructions in the INSTALL file of the distrubution.
|
||
;;
|
||
;; To turn RefTeX Mode on and off in a buffer, use `M-x reftex-mode'.
|
||
;;
|
||
;; To turn on RefTeX Mode for all LaTeX files, add the following lines
|
||
;; to your .emacs file:
|
||
;;
|
||
;; (add-hook 'LaTeX-mode-hook 'turn-on-reftex) ; AUCTeX LaTeX mode
|
||
;; (add-hook 'latex-mode-hook 'turn-on-reftex) ; Emacs latex mode

;; DOCUMENTATION
|
||
;; -------------
|
||
;;
|
||
;; See below for a short summary of how to use RefTeX.
|
||
;;
|
||
;; There is an extensive texinfo document describing RefTeX in detail.
|
||
;; One way to view this documentation is `M-x reftex-info RET'.
|
||
;;
|

|
||
;; Introduction
|
||
;; ************
|
||
;;
|
||
;; RefTeX is a specialized package for support of labels, references,
|
||
;; citations, and the index in LaTeX. RefTeX wraps itself round 4 LaTeX
|
||
;; macros: `\label', `\ref', `\cite', and `\index'. Using these macros
|
||
;; usually requires looking up different parts of the document and
|
||
;; searching through BibTeX database files. RefTeX automates these
|
||
;; time-consuming tasks almost entirely. It also provides functions to
|
||
;; display the structure of a document and to move around in this
|
||
;; structure quickly.
|
||
;;
|
||
;; *Note Imprint::, for information about who to contact for help, bug
|
||
;; reports or suggestions.
|
||
;;
|
||
;; Environment
|
||
;; ===========
|
||
;;
|
||
;; RefTeX needs to access all files which are part of a multifile
|
||
;; document, and the BibTeX database files requested by the
|
||
;; `\bibliography' command. To find these files, RefTeX will require a
|
||
;; search path, i.e. a list of directories to check. Normally this list
|
||
;; is stored in the environment variables `TEXINPUTS' and `BIBINPUTS'
|
||
;; which are also used by RefTeX. However, on some systems these
|
||
;; variables do not contain the full search path. If RefTeX does not work
|
||
;; for you because it cannot find some files, read *Note Finding Files::.
|
||
;;
|
||
;; Entering RefTeX Mode
|
||
;; ====================
|
||
;;
|
||
;; To turn RefTeX Mode on and off in a particular buffer, use `M-x
|
||
;; reftex-mode'. To turn on RefTeX Mode for all LaTeX files, add 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
|
||
;;
|
||
;; RefTeX in a Nutshell
|
||
;; ====================
|
||
;;
|
||
;; 1. Table of Contents
|
||
;; Typing `C-c =' (`reftex-toc') will show a table of contents of the
|
||
;; document. This buffer can display sections, labels and index
|
||
;; entries defined in the document. From the buffer, you can jump
|
||
;; quickly to every part of your document. Press `?' to get help.
|
||
;;
|
||
;; 2. Labels and References
|
||
;; RefTeX helps to create unique labels and to find the correct key
|
||
;; for references quickly. It distinguishes labels for different
|
||
;; environments, knows about all standard environments (and many
|
||
;; others), and can be configured 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)
|
||
;; - prompt for a label string (default for figures and
|
||
;; tables) or
|
||
;; - insert a simple label made of a prefix and a number (all
|
||
;; other environments)
|
||
;;
|
||
;; Which labels are created how is configurable with the variable
|
||
;; `reftex-insert-label-flags'.
|
||
;;
|
||
;; * Referencing Labels
|
||
;; 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 some label context.
|
||
;; Selecting a label inserts a `\ref{LABEL}' macro into the
|
||
;; original buffer.
|
||
;;
|
||
;; 3. Citations
|
||
;; Typing `C-c [' (`reftex-citation') will let you specify a regular
|
||
;; expression to search in current BibTeX database files (as
|
||
;; specified in the `\bibliography' command) and pull out a list of
|
||
;; matches for you to choose from. The list is _formatted_ and
|
||
;; sorted. The selected article is referenced as `\cite{KEY}' (see
|
||
;; the variable `reftex-cite-format' if you want to insert different
|
||
;; macros).
|
||
;;
|
||
;; 4. Index Support
|
||
;; RefTeX helps to enter index entries. It also compiles all entries
|
||
;; into an alphabetically sorted `*Index*' buffer which you can use
|
||
;; to check and edit the entries. RefTeX knows about the standard
|
||
;; index macros and can be configured to recognize any additional
|
||
;; macros you have defined (`reftex-index-macros'). Multiple indices
|
||
;; are supported.
|
||
;;
|
||
;; * Creating Index Entries
|
||
;; To index the current selection or the word at point, type
|
||
;; `C-c /' (`reftex-index-selection-or-word'). The default macro
|
||
;; `reftex-index-default-macro' will be used. For a more
|
||
;; complex entry type `C-c <' (`reftex-index'), select any of
|
||
;; the index macros and enter the arguments with completion.
|
||
;;
|
||
;; * The Index Phrases File (Delayed Indexing)
|
||
;; Type `C-c \' (`reftex-index-phrase-selection-or-word') to add
|
||
;; the current word or selection to a special _index phrase
|
||
;; file_. RefTeX can later search the document for occurrences
|
||
;; of these phrases and let you interactively index the matches.
|
||
;;
|
||
;; * Displaying and Editing the Index
|
||
;; To display the compiled index in a special buffer, type `C-c
|
||
;; >' (`reftex-display-index'). From that buffer you can check
|
||
;; and edit all entries.
|
||
;;
|
||
;; 5. Viewing Cross-References
|
||
;; When point is on the KEY argument of a cross-referencing macro
|
||
;; (`\label', `\ref', `\cite', `\bibitem', `\index', and variations)
|
||
;; or inside a BibTeX database entry, you can press `C-c &'
|
||
;; (`reftex-view-crossref') to display corresponding locations in the
|
||
;; document and associated BibTeX database files.
|
||
;; When the enclosing macro is `\cite' or `\ref' and no other message
|
||
;; occupies the echo area, information about the citation or label
|
||
;; will automatically be displayed in the echo area.
|
||
;;
|
||
;; 6. Multifile Documents
|
||
;; Multifile Documents are fully supported. The included files must
|
||
;; have a file variable `TeX-master' or `tex-main-file' pointing to
|
||
;; the master file. RefTeX provides cross-referencing information
|
||
;; from all parts of the document, and across document borders
|
||
;; (`xr.sty').
|
||
;;
|
||
;; 7. Document Parsing
|
||
;; RefTeX needs to parse the document in order to find labels and
|
||
;; other information. It does it automatically once and updates its
|
||
;; list internally when `reftex-label' and `reftex-index' are used.
|
||
;; 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, the table of contents buffer, or the index
|
||
;; buffer.
|
||
;;
|
||
;; 8. AUCTeX
|
||
;; If your major LaTeX mode is AUCTeX, RefTeX can cooperate with it
|
||
;; (see variable `reftex-plug-into-AUCTeX'). AUCTeX contains style
|
||
;; files which trigger appropriate settings in RefTeX, so that for
|
||
;; many of the popular LaTeX packages no additional customizations
|
||
;; will be necessary.
|
||
;;
|
||
;; 9. Useful Settings
|
||
;; To make RefTeX faster for large documents, try these:
|
||
;; (setq reftex-enable-partial-scans t)
|
||
;; (setq reftex-save-parse-info t)
|
||
;; (setq reftex-use-multiple-selection-buffers t)
|
||
;;
|
||
;; To integrate with AUCTeX, use
|
||
;; (setq reftex-plug-into-AUCTeX t)
|
||
;;
|
||
;; To make your own LaTeX macro definitions known to RefTeX,
|
||
;; customize the variables
|
||
;; `reftex-label-alist' (for label macros/environments)
|
||
;; `reftex-section-levels' (for sectioning commands)
|
||
;; `reftex-cite-format' (for `\cite'-like macros)
|
||
;; `reftex-index-macros' (for `\index'-like macros)
|
||
;; `reftex-index-default-macro' (to set the default macro)
|
||
;; If you have a large number of macros defined, you may want to write
|
||
;; an AUCTeX style file to support them with both AUCTeX and RefTeX.
|
||
;;
|
||
;; 10. Where Next?
|
||
;; Go ahead and use RefTeX. Use its menus until you have picked up
|
||
;; the key bindings. For an overview of what you can do in each of
|
||
;; the different special buffers, press `?'. Read the manual if you
|
||
;; get stuck, of if you are curious what else might be available.
|
||
;; The first part of the manual explains in a tutorial way how to use
|
||
;; and customize RefTeX. The second part is a command and variable
|
||
;; reference.
