<span id="index-Split-HTML-output"></span>
<span id="index-HTML-output_002c-split"></span>
<p>When splitting output at nodes (which is the default),
<code>makeinfo</code> writes HTML output into (basically) one output file
per Texinfo source <code>@node</code>.
</p>
<p>Each output file name is the node name with spaces replaced by
‘<samp>-</samp>’’s and special characters changed to ‘<samp>_</samp>’ followed by
their code point in hex (see <a href="HTML-Xref.html">HTML Xref</a>). This is to make it
portable and easy to use as a filename. In the unusual case of two
different nodes having the same name after this treatment, they are
written consecutively to the same file, with HTML anchors so each can
be referred to independently.
</p>
<p>If <code>makeinfo</code> is run on a system which does not distinguish
case in file names, nodes which are the same except for case (e.g.,
‘<samp>index</samp>’ and ‘<samp>Index</samp>’) will also be folded into the same
output file with anchors. You can also pretend to be on a case
insensitive filesystem by setting the customization variable
<code>CASE_INSENSITIVE_FILENAMES</code>.
</p>
<p>It is also possible to split at chapters or sections with
<samp>--split</samp> (see <a href="Invoking-texi2any.html">Invoking <code>texi2any</code></a>). In that case,
the file names are constructed after the name of the node associated
with the relevant sectioning command. Also, unless
<samp>--no-node-files</samp> is specified, a redirection file is output
for every node in order to more reliably support cross-references to
that manual (see <a href="HTML-Xref.html">HTML Xref</a>).
</p>
<p>When splitting, the HTML output files are written into a subdirectory,
with the name chosen as follows:
</p>
<ol>
<li> <code>makeinfo</code> first tries the subdirectory with the base name
from <code>@setfilename</code> (that is, any extension is removed). For
example, HTML output for <code>@setfilename gcc.info</code> would be
written into a subdirectory named ‘<samp>gcc/</samp>’.
</li><li> If that directory cannot be created for any reason, then
<code>makeinfo</code> tries appending ‘<samp>.html</samp>’ to the directory name.
For example, output for <code>@setfilename texinfo</code> would be written
to ‘<samp>texinfo.html/</samp>’.
</li><li> If the ‘<samp><var>name</var>.html</samp>’ directory can’t be created either,
<code>makeinfo</code> gives up.
</li></ol>
<p>In any case, the top-level output file within the directory
is always named ‘<samp>index.html</samp>’.
</p>
<p>Monolithic output (<code>--no-split</code>) is named according to
<code>@setfilename</code> (with any ‘<samp>.info</samp>’ extension is replaced with
‘<samp>.html</samp>’), <code>--output</code> (the argument is used literally), or
based on the input file name as a last resort
(see <a href="_0040setfilename.html"><code>@setfilename</code></a>).
