<p>
The most general function of all of the above ones (not counting
<tt>command</tt> which is even more powerful in principle but which should
generally be avoided because of performance considerations) is the
<tt>regex</tt> one. Here are some more examples of its use:
<div class="code">
<pre>
// Strip the wx prefix from all identifiers except those starting with wxEVT
%rename("%(regex:/wx(?!EVT)(.*)/\\1/)s") ""; // wxSomeWidget -&gt; SomeWidget
// wxEVT_PAINT -&gt; wxEVT_PAINT
// Apply a rule for renaming the enum elements to avoid the common prefixes
// which are redundant in C#/Java
%rename("%(regex:/^([A-Z][a-z]+)+_(.*)/\\2/)s", %$isenumitem) ""; // Colour_Red -&gt; Red
// Remove all "Set/Get" prefixes.
%rename("%(regex:/^(Set|Get)(.*)/\\2/)s") ""; // SetValue -&gt; Value
// GetValue -&gt; Value
</pre>
</div>
