The principal functional difference is that index entries beginning with a left brace or right brace (‘<samp>{</samp>’ resp. ‘<samp>}</samp>’) can work properly. For example, these simple index entries are processed correctly, including the “index initial” shown in the index: </p> <div class="example"> <pre class="example">@cindex @{ @cindex @} ... @printindex cp </pre></div> <span id="index-Literate-programming_002c-with-Texinfo-and-awk"></span> <span id="index-Texinfo_002c-and-literate-programming"></span> <span id="index-Robbins_002c-Arnold"></span> <span id="index-texiwebjr"></span> <span id="index-ti_002etwjr"></span> <p>Although not a matter of functionality, readers may be interested to know that the new <code>texindex</code> is a literate program (<a href="http://en.wikipedia.org/wiki/Literate_programming">http://en.wikipedia.org/wiki/Literate_programming</a>) using Texinfo for documentation and (portable) <code>awk</code> for code. A single source file, <samp>texindex/ti.twjr</samp> in this case, produces the runnable program, a printable document, and an online document. </p> <p>The system is called TexiWeb Jr. and was created by Arnold Robbins, who also wrote the new <code>texindex</code>. Not coincidentally, he is also the long-time maintainer of <code>gawk</code> (GNU Awk, see <cite><a data-manual="gawk" href="../gawk/index.html#Top">The GNU Awk User’s Guide</a></cite>). The file <samp>texindex/Makefile.am</samp> shows example usage of the system. </p> </div> </body> </html>
