OpenWRT's LuCI WebUI, Torch ML, and embedded interpreters in game engines are also written in Lua. Apache Arrow's C GLib implementation works with Lua. From https://news.ycombinator.com/item?id=38103326 https://news.ycombinator.com/item?id=38103326 : > Apache Arrow already supports C, C++, Python, Rust, Go and has C GLib support Lua: https://github.com/apache/arrow/tree/main/c_glib/example/lua https://github.com/apache/arrow/tree/main/c_glib/example/lua LearnXinYminutes Lua: https://learnxinyminutes.com/docs/lua/ https://learnxinyminutes.com/docs/lua/ OpenWRT is a Make-based Linux distro for embedded devices with limited RAM and flash ROM, x86, and docker. OpenWRT is built on `uci` (and procd and ubusd instead of systemd and dbus). UCI is an /etc/config/* dotted.key=value configuration system which procd sys-v /etc/init.d/* scripts read values in from when regenerating their configuration when $1 is e.g. 'start', 'restart', or 'reload' per sys-v. LuCI is the OpenWRT web UI which is written in Lua; which is now implemented mostly as a JSON-RPC API instead of with server-side HTML templates for usability and performance on embedded devices. Notes on how to write a LuCI app in Lua: https://github.com/x-wrt/luci/commit/73cda4f4a0115bb05bbd3d11d98595e4412ad3b6#commitcomment-131604246 https://github.com/x-wrt/luci/commit/73cda4f4a0115bb05bbd3d1... applications/luci-app-example: https://github.com/openwrt/luci/tree/master/applications/luci-app-example https://github.com/openwrt/luci/tree/master/applications/luc... openwrt/luci//docs: https://github.com/openwrt/luci/tree/master/docs https://github.com/openwrt/luci/tree/master/docs https://openwrt.org/supported_devices https://openwrt.org/supported_devices It's probably impossible to build OpenWRT (and opkg packages) for an RP2040W.

Yes, it's impossible (i'm dev on OpenWRT) because it build toolchain first then, Linux kernel, drives and userland apps.
