Lua has scripted main by default, using an obscure syntax (an ellipsis of all things). |
|||
<lang lua>#!/usr/bin/env lua |
|||
os = require("os") |
|||
function main(arg) |
|||
print("Directory: " .. os.execute("pwd")) |
|||
print("Program: " .. debug.getinfo(1).source) |
|||
print("Number of Args: " .. #arg) |
|||
for i,a in ipairs(arg) do |
|||
print("Arg: " .. a) |
|||
end |
|||
end |
|||
if type(package.loaded[(...)]) ~= "userdata" then |
|||
main(arg) |
|||
else |
|||
module(..., package.seeall) |
|||
end</lang> |
