[Pharo-users] AST: Adding RBComment to a node

[Mehrdad Abdi]

Hello, 

How can I make a comment on a node dynamically? 

- Here is a code i've tried:

b:= RBParser parseMethod: 'foo self x: 2. x:=0. y:=8.'.
node := b body statements at: 1.
node comments: { RBComment with: 'comment' at: node stop + 1 }.
b formattedCode.

- The result:

foo
    self x: 2.    . x:=0. y
    x := 0.
    y := 8

- I expect:

foo
    self x: 2.    "comment"
    x := 0.
    y := 8
