Hi, everyone! First of all, using Roassal is fun and effective :) But while working on AST visualization I found that sometimes Roassal builds wrong tree layout (or maybe I'm just doing something wrong). For instance, try two following scripts in playground: ************************* #1 | ast builder | ast := RBParser parseExpression: 'self foo. self foo'. builder := RTMondrian new. builder shape ellipse size: 15. builder nodes: ast allChildren. builder edges connectFrom: #parent. builder layout tree. builder build. builder view ************************* ************************* #2 | ast builder | ast := RBParser parseExpression: 'self foo. super foo'. builder := RTMondrian new. builder shape ellipse size: 15. builder nodes: ast allChildren. builder edges connectFrom: #parent. builder layout tree. builder build. builder view ************************* First script builds wrong tree. I think it's because somewhere in roassal objects (in this case ast nodes) are compared by value. That is why when we have two equal receivers in script #1 it fails to build a tree.
