The best documentation is at https://refactory.com/rewrite-tool/ What isn't covered, is cascade nodes (`@;messages1), but my first naive attempt did not work as I expected on your example; '(b shape `@method: `@keywords) @;messages1: `@args' -> 'b shape: [ :x | (x `@method: `@keywords) @;messages1: `@args ]' b shape circle size: 15; color: (Color veryLightGray alpha: 0.4); if: [ :value | toBeRed includes: value ] fillColor: Color red -> b shape: [ :x | x circle size: 15 ]; shape: [ :x | x circle color: (Color veryLightGray alpha: 0.4) ]; shape: [ :x | x circle if: [ :value | toBeRed includes: value ] fillColor: Color red ] -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
