Writing Code to Update our Code
summary
Projects move from brittle sed regexes to recast AST transforms that parse and rewrite code while preserving spacing and quote style, then print it back. A packaged ember-watson addon runs transforms for route generation, QUnit assertion updates, and Ember-Data relationship/name fixes. Prototype-extension conversion and many initializer migrations succeed; some initializer cases reach roughly 60% automated coverage. The approach targets actual node patterns not surface text so it works across teams and styles.
