It was thus said that the Great Thomas Jericke once stated:

To answer your question: One of Lua's main use cases is as a

I don't think it's a bad idea to structure your configuration
parameters. And once you do that you don't have that many globals in
configuration files either:
return {
Window = {
x = 5
y = 100
}
}
end
But there's no need for the return ("Why do I need a 'return' in a
configuration file?"). A configuration file like:
name = "A Blog Grows in Cyberspace"
basedir = "$HOME/source/boston/journal"
webdir = "$HOME/source/boston/htdocs"
lockfile = webdir .. ".modblog.lock"
url = "http://www.example.com/blog/";
author = { name = "Joe Blog" , email = "joe@example.com" }
timezone = "-8:00"
adtag = "programming"
debug = false
conversion = "html"
doesn't have to end up setting a bunch of globals:
config = {}
f = ("config.file","t",config)
f()
print(config.name) -- Tadaaaaaah!
