I forgot to tell in the message that there's also a mirror at http://fabiomascarenhas.github.io/lua/

Really good class notes these. But I see they're named 00Introduction.pdf, 01GettingStarted.pdf and so on. Doesn't the author know that all Lua indexes start at 1? :)

The author is Fabio Mascarenhas (http://lua-users.org/wiki/FabioMascarenhas) so he certainly does know. Just makes it more disappointing, though :P

Well, at least the code archives and homework pages are indexed correctly ;)

Actually the "meat" of the course starts on unit 1, unit 0 is more of a recap of where Lua comes from and where it is used. :)

Those are great. I did not expect to learn something new given that Lua is a very simple language but I actually did!
