[Pharo-users] Modifying the AST of a method

From Günter Khyo:

Hello!

I want to replace particular nodes of an AST (such as Assignments or Self sends) with my own nodes. Is there an easy (high-level) way to do this without being familiar with the entire compiler infrastructure?

The problem I am having is that AST nodes maintain internal state such as parent links and, in the case of RBVariables, links to scopes and bindings. There might be many other dependencies I am missing and missing one of them can trigger exceptions with stack traces buried deep in the IR Code-Generator and visitor calls.

For example, if I want to replace an assignment such as

Morph>>position: aPoint

"box := self fullBounds."

with something like

"self assignAndNotifiyDependents: self fullBounds to: 'box' "

Btw: I know there is a rewrite tool, but I want to do it programmatically.

Thanks!
