June 2026 monthly summary for keiyoushi/extensions-source. Delivered a new Tachiyomi manga source extension for 'I am An Evil God', aligned with standard extension patterns, and implemented comprehensive data fetching via HttpSource. Jsoup-based parsing is used to reliably fetch manga details, chapter lists, and page images, with robust error handling for unsupported features to improve user experience. Key improvements include stability and maintainability refinements such as refactoring extension methods, updating build.gradle, and adjusting the site icon for the new source. A notable change to control flow was introducing a managed exception in the latestUpdatesRequest to handle edge cases more predictably. The work is supported by the commit bd6882cccdf4ac91594e3aa468fdc90a7f38aa2c and included collaboration with co-authors. Overall impact: expands Tachiyomi’s catalog with a new reliable source, increases potential user engagement, and enhances code quality for easier future maintenance. Technologies/skills demonstrated: Kotlin-based Tachiyomi extension development, HttpSource patterns, Jsoup parsing, build system (Gradle), error handling, code refactoring, and collaboration.
