Myeongchul Shin developed JSONC-enabled configuration support for the oxc-project/oxc repository, focusing on improving the linting tool’s configurability and developer experience. Using Rust for backend development, he unified configuration handling by enabling both .oxlintrc.json and .oxlintrc.jsonc files, with logic to prefer .json when both are present. He extended LSP file watching and path filtering to support .jsonc, ensuring editor integrations remain synchronized with configuration changes. The implementation leveraged existing JSONC parsing via json_strip_comments::strip(), minimizing code changes while maintaining reliability. Comprehensive test coverage was added for discovery, precedence, and watcher behavior, reflecting a thorough and maintainable engineering approach.
