Lang is a deprecated module. Please remove it for the next version: https://gjs.guide/extensions/review-guidelines/review-guidelines.html#general-advice Learn how to remove Lang from your code: https://gjs.guide/guides/gjs/legacy-class-syntax.html If you need any help with your extension you can ask us on: GNOME Matrix channel: https://matrix.to/#/#extensions:gnome.org IRC Bridge: irc://irc.gimpnet.org/shell-extensions

btw, if you use `spawn_command_line_sync` for the next version we probably reject that. Because you shouldn't block the shell. To find out why you are blocking the shell and how to fix that, read this page: https://gjs.guide/guides/gio/subprocesses.html
