What is this?

QuickCalc (plugins/quickcalc), a community plugin: a fast, keyboard-driven calculator with Basic, Scientific and Programmer modes, live preview, variables, memory and a persistent history. It runs as a bar panel (topbarGlyph) or as a floating window (framePopout), and one IPC keybind toggles either: qs -c shell ipc call quickcalc toggle.

• No window-manager code: the floating window is a Quickshell layer-shell surface, and its corners follow the shell frame rounding through PluginKit Config.frameRadius.
• Imports only QtQuick, Quickshell and Ryoku.PluginKit. Settings go through pluginApi.saveSetting; it writes only state.json in its own state folder.
• The arithmetic engine is pure JS with no eval, and has its own tests (node tests/engine.test.cjs, 101 pass). The tests are for development; the plugin never runs them.
• External commands: wl-copy (copy the result) and mkdir (create the state folder), both declared in the manifest.
• Maintained by me (Klopster), not the Ryoku team. MIT licensed.
