$ brew info lua lua: stable 5.2.4 (bottled) Powerful, lightweight programming language http://www.lua.org/ Not installed From: https://github.com/Homebrew/homebrew/blob/master/Library/Formula/lua.rb ==> Options --universal Build a universal binary --with-completion Enables advanced readline support --without-luarocks Don't build with Luarocks support embedded --without-sigaction Revert to ANSI signal instead of improved POSIX sigaction ==> Caveats Please be aware due to the way Luarocks is designed any binaries installed via Luarocks-5.2 AND 5.1 will overwrite each other in /usr/local/bin. This is, for now, unavoidable. If this is troublesome for you, you can build rocks with the `--tree=` command to a special, non-conflicting location and then add that to your `$PATH`.
Note that package does not have to be installed for finding info.
