+# CDLaTex
+Copyright (c) 2010, 2011, 2012, 2014 Free Software Foundation, Inc.
+**AUTHOR:** Carsten Dominik <carsten.dominik@gmail.com>
+**KEYWORD** tex
+**VERSION:** 4.7
-Fast input methods for LaTeX environments and math
+## Note
+This is a mirror from Carsten Dominik, which is maintained by Songpeng Zu.
+Currently it is the **latest** version.
-This is now the main home for cdlatex.el, the version at
-staff.astro.uva.nl/~dominik will be removed soon.
+## Introduction
+CDLaTeX is a minor mode for Emacs supporting fast insertion of environment
+templates and math stuff in LaTeX. Similar commands are also offered as part of
+the AUCTeX package, but it is not the same - CDLaTeX focuses on speediness for
+inserting LaTeX constructs. I myself am using CDLaTeX on top of AUCTeX.
+
+Here are some of the differences between CDLaTeX and the corresponding parts
of AUCTeX:
+
+1. Environment insertion is template based, and not hook based.
+2. Keyword commands (which are executed by typing a short (2-4 letters)
keyword into
+ the buffer, followed by TAB) give very rapid access to the main environment
+ templates and mathematical constructs.
+3. CDLaTeX knows the difference between
+ text mode and math mode in LaTeX and adapts automatically to that.
+
+## Download & Installation
+You can directly install this package under *melpa* in Emacs. Or you can
+download this file, add it to your load-path.
+
+## Manual
+There is no manual for CDLaTeX, but here is the quick look for the commentary
+section of the Emacs Lisp file, it contains a decent description.
+
+### Turn on CDLaTeX
+
+
+To turn CDLaTeX Minor Mode on and off in a particular buffer, use
+`M-x cdlatex-mode'.
+To turn on CDLaTeX Minor Mode for all LaTeX files, add one of the
+following lines to your .emacs file:
+```lisp
+ (add-hook 'LaTeX-mode-hook 'turn-on-cdlatex) ; with AUCTeX LaTeX mode
+ (add-hook 'latex-mode-hook 'turn-on-cdlatex) ; with Emacs latex mode
+```
+For key bindings, see further down in this documentation.
+CDLaTeX requires texmathp.el which is distributed with AUCTeX.
+Starting with Emacs 21.3, texmathp.el will be part of Emacs.
+
+### ABBREVIATIONS
+CDLaTeX has an abbrev-like mechanism to insert full LaTeX environments and
other
+templates into the buffer. Abbreviation expansion is triggered with the TAB
+key only, not with SPC or RET. For example, typing "ite<TAB>" inserts an
+itemize environment. A full list of defined abbreviations is available with
+the command `C-c ?` (cdlatex-command-help).
+
+#### ENVIRONMENT
+Typing `C-c {`, which means
+**cdlatex-environment**, and uses the minibuffer to
+complete the name of a LaTeX environment and inserts a template
+for this environment into the buffer. These environment
+templates also contain labels created with RefTeX. In a
+template, text needs to be filled in at various places, which we
+call "points of interest". You can use the TAB key to jump to
+the next point of interest in the template.
+
+For many frequently used LaTeX environments, abbreviations are
+available. Most of the time, the abbreviation consists of the
+first three letters of the environment name: `equ<TAB>` expands
+into
+```latex
+\begin{equation}
+\label{eq:1}
+
+\end{equation}
+```
+Similarly, `ali<TAB>` inserts an AMS-LaTeX align environment
+template etc. For a full list of environment abbreviations, use
+`C-c ?`.
+
+Use the command `C-c -` , which means **cdlatex-item** to insert a generalized
+new "item" in any "list"-like environment. For example, in an
+itemize environment, this inserts "\item", in an enumerate
+environment it inserts `\item\label{item:25}` and in an eqnarray
+environment, it inserts `\label{eq:25} \n & &`. When
+appropriate, newlines are inserted, and the previous item is also
+closed with "\\". **cdlatex-item** can also be invoked with the
+abbreviation `it<TAB>`.
+
+#### MATH TEMPLATES
+Abbreviations are also used to insert simple math templates
+into the buffer. The cursor will be positioned properly. For
+example, typing `fr<TAB>` will insert `\frac{}{}` with the
+cursor in the first pair of parenthesis. Typing `lr(<TAB>`
+will insert a **`\left( \right)`** pair and position the cursor in
+between, etc. Again, the TAB key can be used to jump to the
+points in the template where additional text has to be
+inserted. For example in the `\frac{}{}` template, it will
+move you from the first argument to the second and then out of
+the second. For a list of available templates, type `C-c ?`.
+
+### MATHEMATICAL SYMBOLS
+This feature is similar to the functionality in the Math minor mode
+of AUCTeX, and to the input methods of the X-Symbol package. It is
+introduced by the backquote character. Backquote followed by any
+character inserts a LaTeX math macro into the buffer. If
+necessary, a pair of "$" is inserted to switch to math mode. For
+example, typing "\`a" inserts `\alpha` in latex format.
+
+Since LaTeX defines many more mathematical symbols than the alphabet has
letters, different
+sets of math macros are provided. We call the different sets
+"levels". On each level, another LaTeX macro is assigned to a
+given letter. To select the different levels, simply press the
+backquote character several times before pressing the letter. For
+example, typing "\`d" inserts "\delta" (level 1), and typing "\`\`d"
+inserts "\partial" (level 2). Similarly, "`e" inserts "\epsilon"
+and "``e" inserts "\vareppsilon".
+
+On each level, on-thy-fly help will pop up automatically if you
+hesitate to press the next key. The help screen is a window which
+lists all math macros available on the current level. Initially,
+when you type slowly, this window will pop up each time you press
+backquote. However, after you have learned the different keys, you
+will type more quickly and the help window is not shown. Try it
+out: First press "\`" (backquote), wait for the help window and then
+press "a" to get "\alpha". Then press "`" and "b" as a quick
+sequence to get "\beta", without the help window.
+
+The LaTeX macros available through this mechanism are fully
+configurable - see the variable `cdlatex-math-symbol-alist'.
+
+### ACCENTS AND FONTS
+Putting accents on mathematical characters and/or changing the font of a
+character uses key combinations with the quote character "\'" as a prefix.
+The accent or font change is applied to the character or LaTeX macro
+*before* point.
+
+As you can see:
+ - using math accents like ~ outside math mode will throw an error.
+ - the font change used automatically adapts to math mode.
+ - if the item before point is a LaTeX macro, the change applies to the whole
+ macro.
+ - in text mode, the change applies to the entire word before point, while in
+ math mode only the last character is modified.
+ - if the character before point is white space, a dollar or an opening
+ parenthesis, this command just opens an empty template and positions the
+ cursor inside.
+ - when a numeric prefix argument is supplied, the command acts on whole
+ words before the cursor.
+
+In order to insert a normal quote, you can press the quote character twice.
+Also, if the key character is not associated with an accent or font, the
+quote will be inserted. For example, "'t" and "'s" insert just that, so that
+normal text typing will not be disturbed. Just like during the insertion of
+math macros (see above under (4.)), automatic on-the-fly help will pop up
+when you pause after hitting the quote character, but will be suppressed
+when you continue quickly. The available accents and also the prefix key can
+be can be configured - see documentation of the variables
+`cdlatex-math-modify-alist' and `cdlatex-math-modify-prefix'.
+
+### PAIR INSERTION of (), [], {}, and $$
+Dollars and parens can be inserted as pairs. When you type the
+opening delimiter, the closing delimiter will be inserted as well,
+and the cursor positioned between them. You can configure which
+delimiter are inserted pairwise by configuring the variable
+`cdlatex-paired-parens'.
+
+Also, the keys `_' and `^' will insert "_{}" and "^{}",
+respectively, and, if necessary, also a pair of dollar signs to
+switch to math mode. You can use TAB to exit paired parenthesis.
+As a special case, when you use TAB to exit a pair of braces that
+belong to a subscript or superscript, CDLaTeX removes the braces if
+the sub/superscript consists of a single character. For example
+typing "$10^3<TAB>" inserts "$10^3$", but typing "$10^34<TAB>"
+inserts "$10^{34}$"
+
+### THE OVERLOADED TAB KEY
+You may have noticed that we use the TAB key for many different
+purposes in this package. While this may seem confusing, I have
+gotten used to this very much. Hopefully this will work for you as
+well: "when in doubt, press TAB". Here is a summary of what happens
+when you press the TAB key:
+
+The function first tries to expand any abbreviation before point.
+
+If there is none, it cleans up short subscripts and superscripts at
+point. I.e., is the cursor is just before the closing brace in
+"a^{2}", it changes it to "a^2", since this is more readable. If
+you want to keep the braces also for simple superscripts and
+subscripts, set the variable `cdlatex-simplify-sub-super-scripts'
+to nil.
+
+After that, the TAB function jumps to the next point of interest in
+a LaTeX text where one would reasonably expect that more input can
+be put in. This does *not* use special markers in the template,
+but a heuristic method which works quite well. For the detailed
+rules which govern this feature, check the documentation of the
+function `cdlatex-tab'.
+
+
+## CONFIGURATION EXAMPLES
+Check out the documentation of the variables in the configuration
+section. The variables must be set before cdlatex-mode is turned on,
+or, at the latext, in `cdlatex-mode-hook', in order to be effective.
+When changing the variables, toggle the mode off and on to make sure
+that everything is up to date.
+
+Here is how you might configure CDLaTeX to provide environment templates
+(including automatic labels) for two theorem-like environments.
+
+```lisp
+ (setq cdlatex-env-alist
+ '(("axiom" "\\begin{axiom}\nAUTOLABEL\n?\n\\end{axiom}\n" nil)
+ ("theorem" "\\begin{theorem}\nAUTOLABEL\n?\n\\end{theorem}\n" nil)))
+```
+
+The "AUTOLABEL" indicates the place where an automatic label should be
+inserted, using RefTeX. The question mark defines the position of the
+cursor after the template has been inserted into the buffer.
+
+You could also define your own keyword commands "axm" and "thr" to make
+the template insertion quicker (e.g. `axm<TAB>' and `thm<TAB>'):
+```lisp
+ (setq cdlatex-command-alist
+ '(("axm" "Insert axiom env" "" cdlatex-environment ("axiom") t nil)
+ ("thr" "Insert theorem env" "" cdlatex-environment ("theorem") t nil)))
+```
+Here is how to add new math symbols to CDLaTeX's list: In order to put
+all rightarrow commands onto `>, ``>, ```>, and ````> (i.e. several
+backquotes followed by >) and all leftarrow commands onto '<, ``<, ```<,
+and ````<, you could do this in .emacs:
+
+```lisp
+ (setq cdlatex-math-symbol-alist
+ '((?< ("\\leftarrow" "\\Leftarrow" "\\longleftarrow" "\\Longleftarrow"))
+ (?> ("\\rightarrow" "\\Rightarrow" "\\longrightarrow" "\\Longrightarrow"))
+ ))
+```
+To change the prefix key for math accents and font switching, you could
+do something like
+
+```lisp
+ (setq cdlatex-math-modify-prefix [f7])
+```
+## KEY BINDINGS
+Here is the default set of keybindings from CDLaTeX. A menu is also
+installed.
+```lisp
+ $ cdlatex-dollar
+ ( cdlatex-pbb
+ { cdlatex-pbb
+ [ cdlatex-pbb
+ | cdlatex-pbb
+ < cdlatex-pbb
+ ^ cdlatex-sub-superscript
+ _ cdlatex-sub-superscript
+
+ TAB cdlatex-tab
+ C-c ? cdlatex-command-help
+ C-c { cdlatex-environment
+ C-c - cdlatex-item
+ ` cdlatex-math-symbol
+ ' cdlatex-math-modify
+```
+## FAQ
+- Some people find it disturbing that the quote character (') is active
+ for math accents and font switching. I have tried to avoid any letters
+ which are frequently following ' in normal text. For example, 's and 't
+ insert just this. If you still prefer a different prefix key, just
+ configure the variable `cdlatex-math-modify-prefix'.
