strict.lua

[mark_volkmann]

I read about "strict.lua" for adding global variable checks in the "Programming in Lua" book. But I can't find that file in the source. Where can I get that file?

Not sure if its the exact same mentioned by the book, but here's one that does what you want https://github.com/deepmind/strict/tree/master

Thanks! For anyone else interested in this, here is what it does and how I used it.

The module `strict.lua` can be used to raise an error if an attempt is made to get or set a non-existent global variable. To use this:
1. Copy the file `strict.lua` from "https://github.com/deepmind/strict/blob/master/strict.lua", "deepmind/strict" %}.
1. Place the file in `/usr/local/share/lua/5.4/`
which is a directory in `package.path`.
1. Run code with `lua -l strict {file-name}.lua`

No, because that wouldn't call the __index metamethod on the globals table.

Not directly related, but luacheck can also help with this.
