Try this:<br>

Transcript<br>
open;<br>
clear;<br>
show: (Interpreter asCString: #lookupInMethodCacheSel:class:)<br>

It should not be too hard. It's just a matter of creating the CCodeGenerator<br>
for any given class in the same way that VMMaker would have done, and using<br>
it to generate the code into strings that you can browse in the image and/or<br>
display in the browser code pane.<br></blockquote><div><br></div><div>Take a look at the Slang Test Workspace in <a href="http://www.squeakvm.org/svn/squeak/branches/Cog/image/VMMaker-Squeak4.1.image">http://www.squeakvm.org/svn/squeak/branches/Cog/image/VMMaker-Squeak4.1.image</a>.
