Worked on the lewis6991/lua-language-server repository to deliver a configurable feature enhancing asynchronous programming in Lua. Developed the Lua.hint.awaitPropagate setting, which allows developers to control the propagation of --@async annotations through call stacks, reducing the need for manual annotation and improving the developer experience. The setting is disabled by default to maintain compatibility with existing projects. This work involved asynchronous programming concepts, code analysis, and language server development, focusing on providing flexibility for teams working with async Lua code. The implementation demonstrates a targeted approach to developer ergonomics, addressing a nuanced aspect of async code annotation propagation in Lua projects.
