L19[10:22:34] <boiler> is this lua 5.1?

L25[10:40:12] <Saghetti> @boiler

L26[10:40:45] <boiler> then it somehow detects when fucky metatables are in play and doesn't let them ruin everything

L42[10:47:20] <boiler> how is it tostring()ing it if the tostring metamethod ALWAYS errors?

L43[10:47:49] <AmandaC> the default table tostring method, ofc

L44[10:48:28] <boiler> %lua print(setmetatable({}, {\metatable=nil,tostring = function(t) error(t) end }))

L48[10:49:16] <boiler> discord formatting is a pain

L49[10:49:50] <boiler> %lua us="" print(setmetatable({}, {[us.."metatable"]=nil,[us.."tostring"] = function(t) error(t) end }))

L50[10:49:50] <MichiBot> table: 0x7ffa28040800

L51[10:50:46] <AmandaC> That's not doing what you think it is

L52[10:51:08] <AmandaC> Try `("_"):rep(2)`

L53[10:51:12] <AmandaC> or get on IRC like a winner

L54[10:53:15] <boiler> %lua us=("_"):rep(2) print(setmetatable({}, {[us.."metatable"]=nil,[us.."tostring"] = function(t) error(t) end }))

L55[10:53:15] <MichiBot> table: 0x7ff9f0084c00

L56[10:54:15] <AmandaC> the C code for tostring probably tries the metamethod, if it fails,c alls the C default

L57[10:55:27] <boiler> %lua us=("_"):rep(2) print(setmetatable({}, {[us.."metatable"]=nil,[us.."tostring"] = function(t) return(t) end }))

L58[10:55:27] <MichiBot> table: 0x7ffa583581f0

L59[10:56:16] <AmandaC> plus I'm not sure if C print calls tostring

L60[10:56:39] <AmandaC> or whatever MichiBot replaces it with

L61[10:58:35] <boiler> either way, it's not breaking, so you win

L62[10:58:42] <boiler> either way, it's not breaking, so you win mimiru [Edited]

L63[10:59:51] <AmandaC> All it'd do is cause a stack overflow, anyway: https://nc.ddna.co/s/7JmGw8tLtMN7fYY

L64[11:00:03] <AmandaC> which would be caught by michibot and reported as such

L65[11:02:14] <boiler> try the return thing

L66[11:02:40] <boiler> instead of error(t) do return(t). i'm too lazy to fix my lua install atm

L67[11:04:23] <AmandaC> "__tostring must return a string"

L68[11:04:52] <boiler> oh, so that's pretty foolproof.

L69[11:04:54] <AmandaC> regardless, if you did manage to break MichiBot, all it'd earn you is a ban

L70[11:05:38] <boiler> breaking programs is fun though
