yet another spatial IO thing somehow?

local chatbox = peripheral.find "chat_box"
local prefix = os.getComputerLabel():lower()
chatbox.setName(prefix)
local spatial
for _, n in pairs(peripheral.getNames()) do
    if peripheral.getType(n) == "appliedenergistics2:spatial_io_port" then
        spatial = n
    end
end

while true do
    local _, _, player, msg = os.pullEvent "chat_message"
    if player == "gollark" or player == "heav_" or player == "ubq323" then
        if msg:lower():match("^" .. prefix:gsub("%-", "%%-")) then
            rs.setOutput(spatial, true)
            sleep(0.2)
            rs.setOutput(spatial, false)
            chatbox.say "Done!"
        end
        if msg == "!!RESTART" then
            chatbox.say "Doing so."
            sleep(math.random(0, 10))
            chatbox.say "Delay over."
            os.reboot()
        end
        if msg == "!!PING" then
            chatbox.say "Hi, I exist."
        end
    end
end
