This is the online version of the first edition of the book
Programming in Lua, a detailed and authoritative introduction to all
aspects of Lua programming written by Lua's chief architect. The
first edition was aimed at Lua 5.0. It remains largely relevant for
later versions, but there are some differences. All corrections
listed in the errata have been made in the online version.
