assert(condition/nil, error)

local file = assert(io.open("fake_file.lua", "rb"))
assert(false, "error: false unexpected")
assert(a == 0, "a should be 0")
local arg = assert(file)

Parameter	Type	Description
condition/nil	variant
error	string	message

Return Type	Description
variant	passthrough all variables

collectgarbage(what)

"collect": performs a full garbage-collection cycle. This is the default option.
"stop": stops the garbage collector.
"restart": restarts the garbage collector.
"count": returns the total memory in use by Lua (in Kbytes).
"step": performs a garbage-collection step. The step "size" is controlled by arg (larger values mean more steps) in a non-specified way. If you want to control the step size you must experimentally tune the value of arg. Returns true if the step finished a collection cycle.
"setpause": sets arg as the new value for the pause of the collector. Returns the previous value for pause.
"setstepmul": sets arg as the new value for the step multiplier of the collector. Returns the previous value for step.

Parameter	Type	Description
what	string	or nil for "collect"

Return Type	Description
int	depending on the option
