Ah ah, happy to have made you day. Yes, Slang is the awesome thing for
integrating things. You can debug in Pharo, and then compile to C. How cool

Check the FileSystem-Core-Implementation package.
Look at the FileSystemGuide and how ti works, including the
FileSystemVisitor and its Collect and Select visitors down there.
It is interesting material to get to terms with the Visitor/Guide thing.
I reused/cloned a ton of this code for my current project where I do have
to navigate network equipement structures and generate probes along the way.
A tad mind twisting at the beginning but very useful once you get it.
Once you have the guide, you can visit all the way you want. Like here, I
generate HTML tree controls, D3 graphics, SNMP probes etc.
There are samples also for AST, but this is a tad too much for me at the

Ah, swallowing the red pill is nearing.
