OpenRewrite: Transforming Java Code at Scale

An airhacks.fm (airhacks.fm) conversation with Jonathan Schneider (@jon_k_schneider ( / jon_k_schneider ) ) about:
OpenRewrite (docs.openrewrite.org) as an open-source tool for code transformation using lossless semantic trees (docs.openrewrite.org/concepts...) (LSTs),
recipes as programs that manipulate the LST,
YAML (yaml.org) configuration (kafka.apache.org/documentatio...) for defining recipes,
dry run and in-place code modification options,
separation of open-source and commercial aspects of the project,
Moderne (moderne.io) as a SaaS platform for large-scale code analysis and transformation,
visualization features in Moderne including dependency usage violin charts,
impact analysis capabilities,
organizational structure in Moderne for managing large codebases,
integration of OpenRewrite in various IDEs and tools including Amazon Q Code Transformer,
IntelliJ IDEA, and Visual Studio Code (code.visualstudio.com) ,
the business model of open-source and commercial offerings,
the genesis of OpenRewrite from Gradle (en.wikipedia.org/wiki/Gradle) Lint in 2015-2016,
recent momentum in adoption,
Jonathan's background with micrometer (micrometer.io) project,
discussion about IDEs including Visual Studio Code and IntelliJ IDEA,
potential future topics including Micrometer and Spinnaker (spinnaker.io/)
