GitHub has introduced a new feature called GitHub Codesearch, allowing users to search through nearly all public source code available on the platform. Accessible at github.com/codesearch, this tool provides highlighted results for any searched terms, complete with a sidebar showing the breakdown of results by language and repository. Users can refine their searches by selecting specific languages or repositories, enhancing the search precision. The feature is expected to integrate further into GitHub, enabling searches from various pages, such as the front page, user pages, and project pages. Feedback on its functionality and potential applications is encouraged, as GitHub plans to expand its utility.
