    <p>I try to write a Boost.Spirit parser that parses a string that should represent a simple command like "print foo.txt". Each time the input fulfills the grammar a semantic action should be called.</p> <p>Here is the code:</p> <pre><code>template&lt;class Iterator&gt; struct my_parser : qi::grammar&lt;Iterator, void(), qi::ascii::space_type&gt; { void test(std::string const &amp; s) const { std::cerr &lt;&lt; s &lt;&lt; std::endl; } my_parser() : my_parser::base_type(print) { using qi::_1; using qi::char_; filename = *qi::char_("a-zA-Z_0-9./ ") ; print = qi::lit("print") &gt;&gt; filename [ boost::bind(&amp;my_parser::test, this, _1) ] ; } qi::rule&lt;Iterator, std::string()&gt; filename; qi::rule&lt;Iterator, void(), qi::ascii::space_type&gt; print; }; </code></pre> <p>If I try to compile this I get something like:</p> <pre><code>no match for call to ‘(const boost::_mfi::cmf1&lt;void, parser::my_parser&lt;__gnu_cxx::__normal_iterator&lt;const char*, std::basic_string&lt;char&gt; &gt; &gt;, const std::basic_string&lt;char&gt;&amp;&gt;) (parser::my_parser&lt;__gnu_cxx::__normal_iterator&lt;const char*, std::basic_string&lt;char&gt; &gt; &gt;* const&amp;, const boost::phoenix::actor&lt;boost::spirit::argument&lt;0&gt; &gt;&amp;)’ </code></pre> <p>If I replace _1 with <em>"abc"</em> for example the code compiles but phrase_parse() return with false for the input <em>"print foo.txt"</em>. If I comment out the <em>[ boost:bind(...) ]</em> phrase_parse() return with true.</p> <p>Does anyone know what I do wrong? Thanks.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
