FOSDEM (https://fosdem.org), the Free and Open Source Developers European Meeting, has become a traditional meeting point for the Lua community. The Lua community has convened in FOSDEM regularly over the last few years:
We are submitting a devroom proposal for a Minimalistic Languages Devroom together with the Scheme community ( http://community.schemewiki.org/?FOSDEM2019 ) , with whom we split a devroom at FOSDEM 2016 and 2017. The idea is to expand the idea of the full-day Lua/Guile event into a wider scope, inviting other language communities for a cross-polination of ideas.
There a number of talk topics the Lua community can contribute to the room (if you have talk ideas, feel free to add them here!)
