Papers

There are many papers and theses related to Lua. Here are the main ones written by the Lua team. See also the LabLua publications.

The main academic paper about Lua discusses the philosophy behind its design:

Lua – an extensible extension language by R. Ierusalimschy, L. H. de Figueiredo, W. Celes, Software: Practice & Experience 26 #6 (1996) 635–652. [doi] This paper was awarded the first prize (technological category) in the II Compaq Award for Research and Development in Computer Science in 1997. This award was a joint venture of Compaq Computer in Brazil, the Brazilian Ministry of Science and Technology, and the Brazilian Academy of Sciences.
