This repo contains every version of Lua that has been released. It is lua-all.tar.gz in the form of a Git repo: each commit contains the source code of a particular version of Lua, and the commits are chained together in the order that the versions were released.
All commits are tagged with the Lua version. Use git tag to list all
available versions, and git checkout 5.3.4 to check out the source code for
version 5.3.4, for example.
makerepo.rb is a Ruby script that generates this repo from the contents of
lua-all.tar.gz.
Click on a version number below to browse the source code for that version. (Indented versions are branching points.)

To accompany the presentation of the evolution of Lua at HOPL III, here are all releases of Lua. Only the source code is included; for documentation and other files, see the original tarballs at Lua.org.
The code has been slightly updated to compile and run with gcc 4. As a testimony to the portability of Lua, the required changes were minimal: just a trivial change in iolib.c before Lua 2.5. The differences between the original code and the updated code are in DIFFS in each directory.
No attempt has been made to ensure warning-free compilations. A few, mostly trivial, changes would be needed for that, but it is interesting to see the number of warnings decrease to zero in later versions.
To build each release, just go its directory and type 'make'. This will run a simple test for lua and luac (when available). To build and test all releases, just type 'make' at the top level directory.
The simple Makefiles build Lua without any special options. For those, see the original tarballs.
Lua 3.2 may crash when run if compiled with gcc 4. It runs fine in earlier gcc.
Enjoy! -- The Lua team
