+" OPTIONAL: This enables automatic indentation as you type.

+ <title>Inserting Templates</title>
+ <para>
+ This functionality is available via the <literal>TeX-Suite &gt;
+ Templates</literal> menu.
+ This module provides a way to insert custom templates at the beginning of the
+ current file.
+ </para>
+ <para>
+ When &ls; first starts up, it scans the
+ <literal>$VIM/ftplugin/latex-suite/templates/</literal>
+ directory and creates menu items based on the files found there. When
+ you select a template from this menu, the file will be read in above
+ the first line of the current file.
+ </para>
+ <para>
+ A template file can utilize placeholders for initializing the cursor
+ position when the template is read in and subsequent movement. In
+ addition, template files can contain dynamic elements such as the
+ time of creation of a file etc, by using vim expressions.
+ </para>
+ <para>
+ You can place your own templates in the
+ <literal>$VIM/ftplugin/latex-suite/templates/</literal> directory in
+ order for them to be available via the menu. Unless &ls; releases a
+ template with the same name, these files should not get over-written
+ when you install a new release over an existing one.
+ </para>
+ <note>
+ <para>
+ Templates are also accessible for non-gui users with the command
+ |<literal>:TTemplate</literal>|. The argument should be name of
+ the corresponding template file. If the command is called
+ without arguments (preferred usage), then a list of available
+ templates is displayed and the user is asked to choose one of
+ them.

+ <title>&ls; Macros</title>
+ <para>
+ &ls; ships with a very comprehensive set of insert mode and
+ |visual-mode| mappings and menu items to typeset most of the LaTeX
+ elements.
+ </para>
+ <note>
+ <para>
+ These mappings are are not standard mappings in the sense that
+ only the last character is mapped. See plugin/imaps.vim for
+ further documentation. For example, in the case of the mapping
+ <literal>EFI</literal> provided by &ls; you can press the characters
+ '<literal>E</literal>', '<literal>F</literal>' and '<literal>I</literal>'
+ as slowly as you wish (unlike the normal <literal>imap</literal> command
+ where <literal>timeout</literal> issues are involved). The characters are
+ visible as you type them (unlike normal <literal>imap</literal>s) and you
+ can use the movement or backspace key to correct yourself unlike normal
+ mappings.
+ </para>
+ </note>
+ <anchor id="place-holder" />
+ <note id="place-holders">
+ <title>Place Holders</title>
+ <para>
+ Almost all macros provided in &ls; implement Stephen Riem's bracketing
+ system and Gergely Kontra's <literal>JumpFunc()</literal> for handling
+ place-holders. This consists of using "place-holders" to mark off
+ locations where the next relevant editing has to be done. As an example,
+ when you type <literal>EFI</literal> in |insert-mode|, you will get the
+ following:
+ <programlisting>\begin{figure}[h]
+ \centerline{\psfig{figure=&lt;+eps file+&gt;}}
+ \caption{&lt;+caption text+&gt;}
+ \label{fig:&lt;+label+&gt;}
+\end{figure}&lt;++&gt;</programlisting>
+ The text <literal>&lt;+eps file+&gt;</literal> will be selected and
+ you will be left in |select-mode| so that you can continue typing
+ straight away. After having typed in the file name, you can press
+ <literal>&lt;Ctrl-J&gt;</literal> (while still in insert-mode). This will
+ take you directly to the next "place-holder". i.e, <literal>&lt;+caption
+ text+&gt;</literal> will be visually selected with Vim in select mode
+ again for typing in the caption. This saves on a lot of key presses.

+ <title>Over-riding &ls; Macros</title>
+ <para>
+ If you wish to change these macros from their default values, for
+ example, if you wish to change <literal>`w</literal> to expand to

+ IMAP()</link> section.
+ </para>
+ <para>
+ An important thing to note is that if you wish to over-ride macros
+ created by &ls; rather than merely create new macros, you should place
+ the <literal>IMAP()</literal> calls in a script which gets sourced
+ after the files in &ls;. A good place typically is as a file-type
+ plugin file in the
+ <literal>~/.vim/after/ftplugin/</literal> directory. (Use
+ <literal>~/vimfiles</literal> if you are using
+ <literal>WINDOWS</literal>). For example to over-ride
+ <literal>`w</literal> to <literal>\omega</literal> instead of
+ <literal>\wedge</literal>, place the following line in (say)
+ <literal>~/.vim/after/ftplugin/tex_macros.vim</literal>:
+ <programlisting>call IMAP('`w', '\omega', 'tex')</programlisting>
+ </para>
+ <note>
+ <para>
+ It is important to use a file-name which will get sourced on a

+ <section id="inserting-env-threeletter">
+ <title>Method 3: Using three letter sequences</title>
+ <para>
+ Environments can also be inserted by pressing a 3 capital letter
+ sequence starting with an <literal>E</literal>. The sequence of 3
+ letters generally tries to follow the following rules:
+ </para>
+ <orderedlist>
+ <listitem>
+ All environment mappings begin with <literal>E</literal>
+ </listitem>
+ <listitem>
+ If the environment can be broken up into 2 distinct words,
+ such as flushright (flush + right), then the next 2 letters
+ are the first letters of the 2 words. Example:
+ <programlisting>flushleft (_f_lush + _l_eft) ---&gt; EFL
+flushright (_f_lush + _r_ight) ---&gt; EFR
+eqnarray (_e_qn + _a_rray) ---&gt; EEA</programlisting>
+ If on the other hand, the environment name cannot be broken
+ up into 2 distinct words, then the next 2 letters are the
+ first 2 letters of the name of the environment.
+ Example:
+ <programlisting>equation (_eq_uation) ---&gt; EEQ</programlisting>
+ </listitem>
+ </orderedlist>
+ <para>
+ Unfortunately there are some environments that cannot be
+ split in two words and first two letters in name are
+ identical. In this case shortcut is created from E, first and
+ last letter. Example:
+ <programlisting>quote (_q_uot_e_) ---&gt; EQE
+quotation (_q_uotatio_n_) ---&gt; EQN</programlisting>
+ Of course, not every last one of the environments can follow
+ this rule because of ambiguities. In case of doubt, pull down
+ the Tex-Environments menu. The menu item should give the hint
+ for the map.

+ <section id="enclosing-env-f5">
+ <title>Method 1: Pressing <literal>&lt;F5&gt;</literal></title>

+ prompt you with a list of environments. (This list can be customized
+ via the <link
+ linkend="Tex_PromptedEnvironments">g:Tex_PromptedEnvironments</link>
+ setting). You can either choose from this list or type in a new

+ </section>
+ <section id="enclosing-env-threeletter">
+ <title>Method 2: Using three letter mappings</title>
+ <para>
+ You can also select text visually and press a sequence of three

+ character) and the selected text will be enclosed in the chosen
+ environment. The three letter sequence follows directly from the
+ three letter sequence used to insert environments as described <link
+ linkend="inserting-env-threeletter">here</link>. The following
+ example describes the rule used:
+ </para>
+ <para>
+ If <literal>ECE</literal> inserts a
+ <literal>\begin{center}...\end{center}</literal> environment, then to
+ enclose a block of selected text in
+ <literal>\begin{center}...\end{center}</literal>, simply select the

+ leading <literal>E</literal> is converted to <literal>,</literal> and
+ the next 2 letters are small case.
+ </para>
+ </section>
+ <para>
+ Some of the visual mode mappings are sensitive to whether you
+ choose line-wise or character-wise. For example, if you choose a
+ word and press <literal>,ce</literal>, then you get
+ <literal>\centerline{word}</literal>, whereas if you press
+ <literal>,ce</literal> on a line-wise selection, you get:

+ <para>
+ Pressing <literal>&lt;S-F5&gt;</literal> in normal mode detects which

+ <programlisting>\begin{eqnarray}
+ \begin{array}{ccc}

+\end{eqnarray}</programlisting>
+ if you are located in the middle "2 &amp; 3 &amp; 4" line, then pressing

+ If you mistype one of the letters of the lhs, then the mapping is

+ mapped.
+ </para>
+ <para>
+ If you have two mappings which end in a common
+ <literal>lhs</literal>, then the mapping with the longer
+ <literal>lhs</literal> is used. For example, if you do

+ With this, typing <literal>EFE</literal> is equivalent to typing

+ <para>
+ In order to compile &latex; files into various formats, &ls; needs to know
+ which external programs to call and in which way they need to be called.
+ This information is provided to &ls; via a number of "rules". For each
+ format you want to compile to, you need to specify a rule. A rule is
+ specified by defining a variable of the form:
+ <programlisting>g:Tex_CompileRule_&lt;format&gt;</programlisting>
+ where <literal>&lt;format&gt;</literal> is a string like
+ <literal>"pdf"</literal>, <literal>"dvi"</literal> etc.
+ </para>

+ documents into DVI.
+ <programlisting>g:Tex_CompileRule_dvi = 'latex --interaction=nonstopmode $*'</programlisting>

+ <title>Handling dependencies in compilation</title>
+ <para>
+ &ls; also handles compiling dependencies automatically via certain

+ For example, if in your case, you use
+ <programlisting>.tex -&gt; .dvi -&gt; .ps -&gt; .pdf</programlisting>
+ to generate <literal>pdf</literal> files from <literal>dvi</literal>

+ <programlisting>
+let g:Tex_FormatDependency_pdf = 'dvi,ps,pdf'
+</programlisting>
+ This is a comma separated string of formats specifying the order in
+ which the formats to be compiled into should be chosen. With this
+ setting, if you set the target format to <literal>pdf</literal>, then
+ the next time you compile via the <literal>\ll</literal> shortcut, &ls;
+ will first generate a <literal>dvi</literal> file, then use that to
+ generate the <literal>ps</literal> file and finally create the
+ <literal>pdf</literal> file from that.

+ &ls; does this via the global variable <link
+ linkend="Tex_IgnoredWarnings"><literal>g:Tex_IgnoredWarnings</literal></link>.
+ This is a list of patterns, which can be used to filter out (or ignore)
+ some or the warnings and errors reported by the compiler. See the link

+ The order of the words in the <literal>Tex_FoldedXXXX</literal>
+ variables is <emphasis>important</emphasis>. The order defines the
+ order in which the folds are nested. For example, the value
+ <literal>"subsection,section"</literal> for the
+ <literal>Tex_FoldedSections</literal> variable will not fold any
+ subsections at all. This is because the folds are created in the
+ <emphasis>reverse</emphasis> order in which they occur in the
+ <literal>Tex_FoldedSections</literal> setting and also, once a fold is
+ created, the interior of the fold is not examined for creating
+ additional folds. In the above case, this means that a
+ <literal>\section</literal> is folded first and then its interior is
+ not examined further. The correct value should have been
+ <literal>"section,subsection"</literal>
+ </para>
+ <anchor id="fold-setting-adding" />
+ <para>
+ Each of the fold setting variables
+ <literal>Tex_FoldedSections</literal>,
+ <literal>Tex_FoldedEnvironments</literal> etc., as explained previously
+ is a comma separated string of variables. However, to make it easier
+ to <emphasis>add</emphasis> to the default settings without having to
+ repeat the whole default setting again, &ls; uses the following logic
+ in forming the complete setting string from the
+ <literal>Tex_FoldedXXXX</literal> variables. If the variable starts with
+ a comma, then <literal>Tex_FoldedXXXX</literal> is added to the end of
+ the default string rather than replacing it. Similarly, if it ends
+ with a comma, then it will be prepended to the beginning of the
+ default setting rather than replacing it.
+ </para>
+ <para>
+ For example, if <literal>Tex_FoldedEnvironments</literal> is set to the
+ string <literal>"myenv"</literal>, then only an environment of the
+ form <literal>\begin{myenv}</literal> will be folded. However, if the
+ <literal>Tex_FoldedEnvironments</literal> setting is
+ <literal>",myenv"</literal>, then the <literal>\begin{myenv}</literal>
+ environment will be folded after all other environments in the default
+ setting have been folded. On the other hand if
+ <literal>Tex_FoldedEnvironments</literal> is of the form
+ <literal>"myenv,"</literal>, the <literal>\begin{myenv}</literal>
+ environment will be folded before the rest of the environments in the
+ default setting.

+ <title>Editing the folding.vim file directly</title>
+ <para>
+ If you are using version 1.5 of &ls; or older, you will need to
+ directly edit the
+ <literal>$VIM/ftplugin/latex-suite/folding.vim</literal> file if you
+ wish to modify the folding scheme. You will need to modify the
+ function <literal>MakeTexFolds()</literal> defined in that file to
+ modify the fold syntax. <literal>MakeTexFolds</literal> makes a number
+ of calls to <literal>AddSyntaxFoldItem</literal>. Each such call
+ defines a new "fold item". The order in which these calls are made
+ defines how the folds are nested. For example, if you desire an
+ <literal>figure</literal> environment to be nested within a
+ <literal>section</literal>, then you should define the fold for the
+ <literal>figure</literal> first. The syntax of
+ <literal>AddSyntaxFoldItem</literal> is as follows:
+ <programlisting>AddSyntaxFoldItem(startpat, endpat, startoff, endoff [, startskip, endskip])</programlisting>
+ If the last two arguments are omitted, then they are assumed to default
+ to the empty strings <literal>''</literal>.
+ The explanation for each argument is as follows:

+ <literal>startoff</literal> and <literal>endoff</literal> are
+ necessary when the folding region does not have a specific end
+ pattern corresponding to a start pattern. for example in &latex;,
+ <literal>\section{Section Name}</literal> defines the beginning of

+ A Pattern Which Defines The Beginning Of A "Skipped" Region.
+
+ For example, suppose we define a \itemize fold as follows:
+ <programlisting><literal>startpat</literal> = '^\s*\\item',
+<literal>endpat</literal> = '^\s*\\item\|^\s*\\end{\(enumerate\|itemize\|description\)}',
+<literal>startoff</literal> = 0,
+<literal>endoff</literal> = -1</programlisting>
+
+ This defines a fold which starts with a line beginning with an
+ <literal>\item</literal> and ending one line before a line beginning with an
+ <literal>\item</literal> or <literal>\end{enumerate}</literal> etc.
+
+ Then, as long as <literal>\item</literal>'s are not nested things are fine.
+ However, once items begin to nest, the fold started by one
+ <literal>\item</literal> can end because of an
+ <literal>\item</literal> in an <literal>\itemize</literal>
+ environment within this <literal>\item</literal>. i.e, the following can happen:
+
+ <programlisting>\begin{itemize}
+\item Some text &lt;------- fold will start here
+This item will contain a nested item
+\begin{itemize} &lt;----- fold will end here because next line contains \item...
+\item Hello
+\end{itemize} &lt;----- ... instead of here.
+\item Next item of the parent itemize
+\end{itemize}</programlisting>
+
+ Therefore, in order to completely define a folding item which
+ allows nesting, we need to also define a "skip" pattern.
+ <literal>startskip</literal> and end skip do that.
+ Leave '' when there is no nesting.
