Most LaTeX compilers need to be re-run several times in several
commonly occurring situations in order to get a final camera ready copy.
For example, when <code class="literal">\label</code>'s change, when new
<code class="literal">\cite</code> commands are added etc. If the target format
you are compiling to requires multiple compilations, then you will
need to include the format in the
<code class="literal">g:Tex_MultipleCompileFormats</code> setting. This is a
comma separated string of formats which need multiple compilations to
be generated correctly.
</p><p>
By default, this setting contains just the <code class="literal">dvi</code>
format. If you use the <code class="literal">pdflatex</code> compiler to generate
<code class="literal">pdf</code> files, then you might want to also include
<code class="literal">pdf</code> into the above setting.
</p><p>
For every format included in the
<code class="literal">g:Tex_MultipleCompileFormats</code> setting described
above, Latex-Suite will use the following logic to generate the file. Note
that although the following description uses <code class="literal">latex</code>
to refer to the compiler, it could be some other compiler such as
<code class="literal">pdflatex</code> for generating <code class="literal">pdf</code>
output.
</p><p>
</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">If there was a <code class="literal">.idx</code> file, then remember
its contents.</li><li class="listitem">Run <code class="literal">latex</code>.</li><li class="listitem">If the <code class="literal">.idx</code> file changed due to the latex
compiler, then run <code class="literal">makeindex</code> to redo the
<code class="literal">.ind</code> file and then remember to rerun latex.
</li><li class="listitem"><p>
If the <code class="literal">.aux</code> file generated by the latex
compiler contains a <code class="literal">\bibdata</code> line, then it
means that we are using a <code class="literal">.bib</code> file. Therefore,
run <code class="literal">bibtex</code>.
</p><div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
This means that we will always run <code class="literal">bibtex</code>
whenever we use the <code class="literal">\bibliography</code> command
whether or not we actually need to. At this time, Latex-Suite does not
parse the <code class="literal">.aux</code> file before and after the latex
compiler to see if we are required to rerun
<code class="literal">bibtex</code>.
</p></div></li><li class="listitem">
If the <code class="literal">.bbl</code> file changes because of this, then
remember to rerun latex again.
</li><li class="listitem">Also, we check to see if the LaTeX compiler gives certain
standard warnings which notify that we need to compile once again. In
this case also, remember to rerun LaTeX.</li><li class="listitem">If we found we had to rerun latex, then we repeat
the steps above but not running <code class="literal">makeindex</code> or
<code class="literal">bibtex</code> again.</li></ol></div><p>
</p><p>
The LaTeX file is compiled atmost 5 times using this logic. These
steps will ensure that on most platforms/environments, you will get a
clean output with all the cross-references, citations etc correctly
labelled and ordered.
