Re: howto run 5.3 alongside 5.2?

I totally second this need. I've been looking for tools like RVM (rvm.io) for Lua for years.

I would like to switch from 5.2 to 5.3. 

However, if incompatibilities arise then a switch back to 5.2 should be easy. Something like LUA_VERSION=5.3 instead of LUA_VERSION=5.2 in the .bashrc file.

My question: if I do "make install" in the 5.3 codebase is this still doable? Or will there be confusion between the two versions, making a simple switch in this manner undoable?

By the way, in the .bashrc-file I have configured lua as follows:

LUA_VERSION=5.2

export LUA_VERSION

LUA_DIR=/usr/local

export LUA_DIR

LUA_INCL=$LUA_DIR/include

export LUA_INCL

LUA_SHAREDIR=$LUA_DIR/share/lua/$LUA_VERSION

export LUA_SHAREDIR

LUA_LIBDIR=$LUA_DIR/lib/lua/$LUA_VERSION

export LUA_LIBDIR

LUA_PATH="./?.lua;./?/?.lua;$LUA_SHAREDIR/?.lua;$LUA_SHAREDIR/?/?.lua"

export LUA_PATH

LUA_CPATH="./?.so;./?/?.so;$LUA_LIBDIR/?.so;$LUA_LIBDIR/?/?.so"

export LUA_CPATH
