Hello,
When creating a module sometimes is also useful to run it from the
command line as a standalone application.
How to discover the invoke method?
Here's how I'm doing now:
-- checks if the module is being 'required' or executed
local STANDALONE = (debug.getinfo(1).short_src == (arg and arg[0]))
module ((...) or 'default_name')
...
if STANDALONE then
whatever()
end
You can use the following:
local STANDALONE = type(package.loaded[...]) ~= "userdata"
There's an explanation of how it works in this message:
