https://svn.boost.org/trac10/ticket/808 <pre class="wiki">No where in the documentation the expected syntax of the config_file is mentioned. I found on the code the comment http://www.google.com/codesearch?hl=en&amp;q=+file:config_file.hpp+show:Zye14269keo:YJNqZ7IaevU:1tGSWV4a4yE&amp;sa=N&amp;cd=4&amp;ct=rc&amp;cs_p=http://spirit.sourceforge.net/dl_more/program_options.zip&amp;cs_f=boost/program_options/config_file.hpp#a0 /** Standalone parser for config files in ini-line format: Config file can not contain arguments. - '#' is comment character: it is ignored together with the rest of the line. - variable assignments are in the form name '=' value. spaces around '=' are trimmed. - Section names are given in brackets. The actuall variable name is constructed by combining current section name and variable name, with dot between. If section_name already contains dot at the end, new dot is not inserted. For example: @verbatim [gui.accessibility] visual_bell=yes @endverbatim will result in option "gui.accessibility.visual_bell" with value "yes" been returned. */ Such kind of information should be on the documentation. </pre> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/808 Trac 1.4.3 Daryle Walker Fri, 03 Aug 2007 12:19:15 GMT https://svn.boost.org/trac10/ticket/808#comment:1 https://svn.boost.org/trac10/ticket/808#comment:1 <ul> <li><strong>component</strong> <span class="trac-field-old">None</span> → <span class="trac-field-new">program_options</span> </li> <li><strong>severity</strong> → <span class="trac-field-new">Problem</span> </li> </ul> Ticket Vladimir Prus Tue, 07 Aug 2007 13:55:42 GMT https://svn.boost.org/trac10/ticket/808#comment:2 https://svn.boost.org/trac10/ticket/808#comment:2 <ul> <li><strong>status</strong> <span class="trac-field-old">assigned</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> <span class="trac-field-old">None</span> → <span class="trac-field-new">fixed</span> </li> </ul> <p> (In <a class="changeset" href="https://svn.boost.org/trac10/changeset/38495" title="Document config file support in more detail.
