Latex-Suite also handles compiling dependencies automatically via certain
rules which specify the "dependency chain" for each target format.
For example, if in your case, you use
</p><pre class="programlisting">.tex -> .dvi -> .ps -> .pdf</pre><p>
to generate <code class="literal">pdf</code> files from <code class="literal">dvi</code>
files, then you will need to specify the following setting in your
Latex-Suite configuration (see <a class="link" href="customizing-latex-suite.html" title="11 Customizing Latex-Suite">customizing Latex-Suite</a> for where
these settings should go):
</p><pre class="programlisting">
let g:Tex_FormatDependency_pdf = 'dvi,ps,pdf'
</pre><p>
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 <code class="literal">pdf</code>, then
the next time you compile via the <code class="literal">\ll</code> shortcut, Latex-Suite
will first generate a <code class="literal">dvi</code> file, then use that to
generate the <code class="literal">ps</code> file and finally create the
<code class="literal">pdf</code> file from that.
</p><div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
If any of the intermediate formats is listed in the
<code class="literal">g:Tex_MultipleCompileFormats</code> setting as described
in the section <a class="link" href="compiling-multiple.html" title="6.3 Compiling multiple times">Compiling multiple
times</a>, then Latex-Suite might make multiple calls to the compiler to
generate the output file of that format.
</p></div><p>
Along with the <code class="literal">g:Tex_FormatDependency_{format}</code>
setting, you should ofcourse specify the rule for compiling to each of
the formats as described in the <a class="link" href="compiler-rules.html" title="6.1 Setting Compilation rules">previous
section</a>. For example, with the setting above, you could use:
</p><pre class="programlisting">
let g:Tex_CompileRule_dvi = 'latex --interaction=nonstopmode $*'
let g:Tex_CompileRule_ps = 'dvips -Ppdf -o $*.ps $*.dvi'
let g:Tex_CompileRule_pdf = 'ps2pdf $*.ps'</pre><p>
</p><div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
By default, Latex-Suite does not specify any compiler dependencies. Each
target format for which a rule has been derived will be compiled
independently.
