Minetest Mod: editor

Flexible text/code editor for minetest

minetest.register_on_player_receive_fields(function(player, formname, fields)

That won't save the player's filesystem, or unload it from memory when they log off. To do that, you'll need to register on_joinplayer, on_leaveplayer, and on_shutdown callbacks.
