to specify where to put the output. With the CommandLine library, this is
represented like this:</p>
-<p><tt>
-<a name="value_desc_example">
-<a href="#cl::opt">cl::opt</a><string> OutputFilename("<i>o</i>", <a href="#cl::desc">cl::desc</a>("<i>Specify output filename</i>"), <a href="#cl::value_desc">cl::value_desc</a>("<i>filename</i>"));</a>
-</tt></p>
+<a name="value_desc_example"></a>
+<pre>
+<a href="#cl::opt">cl::opt</a><string> OutputFilename("<i>o</i>", <a href="#cl::desc">cl::desc</a>("<i>Specify output filename</i>"), <a href="#cl::value_desc">cl::value_desc</a>("<i>filename</i>"));
+</pre>
<p>This declares a global variable "<tt>OutputFilename</tt>" that is used to
capture the result of the "<tt>o</tt>" argument (first parameter). We specify
<pre>
bool DebugFlag; <i>// the actual value</i>
static <a href="#cl::opt">cl::opt</a><bool, true> <i>// The parser</i>
-Debug("<i>debug</i>", <a href="#cl::desc">cl::desc</a>("<i>Enable debug output</i>")</a>, <a href="#cl::Hidden">cl::Hidden</a>,
+Debug("<i>debug</i>", <a href="#cl::desc">cl::desc</a>("<i>Enable debug output</i>"), <a href="#cl::Hidden">cl::Hidden</a>,
<a href="#cl::location">cl::location</a>(DebugFlag));
</pre>
strategy basically looks like this:</p>
<p><tt>parse(string OrigInput) {</tt>
+
<ol>
<li><tt>string input = OrigInput;</tt>
<li><tt>if (isOption(input)) return getOption(input).parse();</tt> <i>// Normal option</i>
input = OrigInput;<br>
while (!isOption(input) && !input.empty()) input.pop_back();<br>
}</tt>
-<li><tt>if (!OrigInput.empty()) error();</tt>
-</tt>
+<li><tt>if (!OrigInput.empty()) error();</tt></li>
</ol>
-<tt>}</tt></p>
+
+<p><tt>}</tt></p>
