Re: 2 Lua on the same system : how to segregate libraries / rocks ?

[Philippe Verdy <verdyp@...>]

Why not setting the environment in the command line or script launching your Conky, with just the appropriate Lua version in its path ?
Consider setting a shell variable storing the "5.1" or "5.3" version you want, then use that variable to set the LUA_PATH, something like:

#!/bin/bash
LUA_VER=5.1
LUA_PATH="./?.lua;/usr/lib/lua/luarocks/share/lua/$LUA_VER/?.lua;/usr/lib/lua/luarocks/share/lua/$LUA_VER/?/init.lua;/usr/lib/lua/ $LUA_VER /?.lua;/usr/lib/lua/ $LUA_VER /?/init.lua"

conky ...

Hello,

after upgrading my Gentoo, I discovered that some tools (like Conky) supports on Lua 5.3 now.

Which is problematic for me as I'm still having other tools needing Lua 5.1

Is it a way to integrate Lua's versions in

LUA_PATH

and

LUA_CPATH

???? For the moment, I have something like this one,

LUA_PATH='./?.lua;/usr/lib/lua/luarocks/share/lua/5.1/?.lua;/usr/lib/lua/luarocks/share/lua/5.1/?/init.lua;/usr/lib/lua/5.1/?.lua;/usr/lib/lua/5.1/?/init.lua'

but it is took in account by both versions so creating problem issue with 5.3 tools.

Thanks

Laurent
