Episode notes
Type Attribution
- OpenRewrite uses "type attribution," layering semantic information onto ASTs.
- This allows it to understand the meaning of code symbols, enabling more accurate and complex refactoring.
Incremental Upgrades
- Incrementally upgrade dependencies and language versions.
- Avoid large jumps to minimize complexity and risk.
Pull vs. Push Change
- Favor "pull-based change," empowering product teams to initiate code modifications using provided automation.
- Avoid "push-based change," where central teams issue pull requests, as it often leads to low merge rates.
