Also port some "glaringly obvious" bugfixes from HEAD. Hope it doesn't cause problems. [SVN r35237]

<a name="what_is_pyste_"></a><h2>What is Pyste?</h2><p>
|
|
Pyste is a <a href="../../index.html">
|
|
Boost.Python</a> code generator. The user specifies the classes and
|
|
functions to be exported using a simple <i>interface file</i>, which following the
|
|
<a href="../../index.html">
|
|
Boost.Python</a>'s philosophy, is simple Python code. Pyste then uses <a href="http://www.gccxml.org">
|
|
GCCXML</a> to
|
|
parse all the headers and extract the necessary information to automatically
|
|
generate C++ code.</p>
|
|
<a name="example"></a><h2>Example</h2><p>
|
|
Let's borrow the class <tt>World</tt> from the <a href="../../doc/tutorial/doc/html/python/exposing.html">
|
|
tutorial</a>: </p>
|
|
<code><pre>
|
|
<span class=keyword>struct </span><span class=identifier>World
|
|
</span><span class=special>{
|
|
</span><span class=keyword>void </span><span class=identifier>set</span><span class=special>(</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string </span><span class=identifier>msg</span><span class=special>) { </span><span class=keyword>this</span><span class=special>-></span><span class=identifier>msg </span><span class=special>= </span><span class=identifier>msg</span><span class=special>; }
|
|
</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string </span><span class=identifier>greet</span><span class=special>() { </span><span class=keyword>return </span><span class=identifier>msg</span><span class=special>; }
|
|
</span><span class=identifier>std</span><span class=special>::</span><span class=identifier>string </span><span class=identifier>msg</span><span class=special>;
|
|
};
|
|
</span></pre></code>
|
|
<p>
|
|
Here's the interface file for it, named <tt>world.pyste</tt>:</p>
|
|
<code><pre>
|
|
<span class=identifier>Class</span><span class=special>(</span><span class=string>"World"</span><span class=special>, </span><span class=string>"world.h"</span><span class=special>)
|
|
</span></pre></code>
|
|
<p>
|
|
and that's it!</p>
|
|
<p>
|
|
The next step is invoke Pyste in the command-line:</p>
|
|
<code><pre>python pyste.py --module=hello world.pyste</pre></code><p>
|
|
this will create a file "<tt>hello.cpp</tt>" in the directory where the command was
|
|
run. </p>
|
|
<p>
|
|
Pyste supports the following features:</p>
|
|
<ul><li>Functions</li><li>Classes</li><li>Class Templates</li><li>Virtual Methods</li><li>Overloading</li><li>Attributes </li><li>Enums (both "free" enums and class enums)</li><li>Nested Classes</li><li>Support for <tt>boost::shared_ptr</tt> and <tt>std::auto_ptr</tt></li><li>Global Variables</li></ul><table border="0">
