Is a useless function, it do a piece of lua inside of a string.
If you run it:
It will print:
Lua:
function string:load()
for lua in self:gmatch('<%%lua(.-)%%>') do
local printed = ""
local f,err = loadstring(lua)
if not f and err then
printed = err
elseif f then
local r,err = pcall(f)
err = err or ''
printed = err
end
self = self:gsub('<%%lua.-%%>',printed,1)
end
return self
end
Lua:
local str = [[<%lua
math.randomseed(os.time())
%>
My name is mock and i am a bear.
Time now is <%lua return os.date('%H:%M:%S') %>
Random number: <%lua return math.random(0,1000000) %>
Error: <%lua error('omg') %>
Syntax error: <%lua dogas %>
