You don't have access to the Lua version in rockspecs. But since the number of Lua versions is manageable, you could provide multiple different rockspecs. This is what I have done for my Testy[1] project, and it works great so far. I use `-51`, `-52`, and `-53` as the rockspec revision. In the dependencies table, I make sure that the rockspec is valid only for the intended Lua version (e.g. `lua ~> 5.1`), and in the `build.install` table I copy the versioned script (`testy-5.1` and additionally an unversioned script (`testy.lua`). The unversioned one may be overwritten by later installs for different Lua versions, the versioned one should stay. > > D. > HTH, Philipp [1]: https://github.com/siffiejoe/lua-testy/tree/master/rockspecs ------------------------------------------------------------------------------ _______________________________________________ Luarocks-developers mailing list Luarocks-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/luarocks-developers
