| <a class="index-entry-id" id="index-Braces_002c-in-index-entries"></a> |
| <p>In Texinfo version 6, released in 2015, the <code class="command">texindex</code> program |
| was completely reimplemented. The principal functional difference is |
| that index entries beginning with a left brace or right brace |
| (‘<samp class="samp">{</samp>’ resp. ‘<samp class="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-preformatted">@cindex @{ |
| @cindex @} |
| ... |
| @printindex cp |
| </pre></div> |

| <a class="index-entry-id" id="index-Literate-programming_002c-with-Texinfo-and-awk"></a> |
| <a class="index-entry-id" id="index-Texinfo_002c-and-literate-programming"></a> |
| <a class="index-entry-id" id="index-Robbins_002c-Arnold"></a> |
| <a class="index-entry-id" id="index-texiwebjr"></a> |
| <a class="index-entry-id" id="index-ti_002etwjr"></a> |
| <p>Although not a matter of functionality, readers may be interested to |
| know that the new <code class="command">texindex</code> is a literate program |
| (<a class="url" href="http://en.wikipedia.org/wiki/Literate_programming">http://en.wikipedia.org/wiki/Literate_programming</a>) using |
| Texinfo for documentation and (portable) <code class="code">awk</code> for code. A |
| single source file, <samp class="file">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 class="command">texindex</code>. Not |
| coincidentally, he is also the long-time maintainer of <code class="command">gawk</code> |
| (GNU Awk, see <cite class="cite"><a data-manual="gawk" href="https://www.gnu.org/software/gawk/manual/html_node/index.html#Top">The GNU Awk User’s Guide</a></cite>). The file |
| <samp class="file">texindex/Makefile.am</samp> shows example usage of the system. |
