OCCompilerASTPlugin

I have one question about Opal Compiler.

I would like do an AST transformation before using the compiler. If I
understand correctly, I have to built a subclass of
OCCompilerASTPlugin ? Is it correct ?
Any documentation more update about Opal than this :
https://github.com/SquareBracketAssociates/PharoLimbo/tree/master/Opal
Thank you.

Yes. See the example ASTPluginMeaningOfLife

Plugins are not active by default, you need to compile with a compiler that includes your plugin.
e.g. add on the class side

compiler
        "the example plugin is active for this class"
        ^super compiler addPlugin: ASTPluginMeaningOfLife.

to enable it for this hierarchy.
 ( see ASTTransformExamplePluginActive )

There is the paper: https://marcusdenker.de/publications/Bera13a-OpalIWST.pdf

But it is not a tutorial.
