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.
Thanks,
Mark
