说明
Looking Glass is the integrated debugger, inspector, and JavaScript REPL of GNOME Shell. It is opened from inside a running GNOME session by pressing Alt+F2 and entering the keyword lg. It is intended for debugging the shell itself and writing or troubleshooting GNOME Shell extensions. The interface offers four panes. The Evaluator is an interactive JavaScript prompt with full access to the GNOME Shell process, including the St, Clutter, Meta, and GLib APIs. The Windows pane lists open windows. The Extensions pane shows installed shell extensions and links to their source. The Errors pane displays logged errors (in newer releases these are typically routed to journalctl). A picker tool in the top-left lets the user click a UI element on screen to retrieve the corresponding actor in the evaluator for inspection. Press Esc in the evaluator pane to dismiss Looking Glass.
