Worked on improving environment variable handling for the zed-industries/zed repository, focusing on Nushell’s non-interactive mode. Addressed a bug where environment variables were not reliably loaded by modifying the shell invocation to use the -e flag for environment retrieval and ensuring sessions terminated cleanly with exit. This approach eliminated startup errors and improved compatibility with downstream tools such as language servers. The solution was implemented in Rust, leveraging environment management and shell scripting skills, and was tested across multiple Nushell and Zed versions on NixOS. Release notes were updated to reflect the fix, enhancing reliability for developers using Nushell as their shell.
