Here's a first iteration: installation is simple [1]. Tested on Debian Squeeze and Windows XP with LfW. $ luarocks help show luarocks show <argument> show - Shows information about an installed rock. <argument> is an existing package name. Without any flags, show all module information. With these flags, return only the desired information: --home home page of project --modules all modules provided by this package as used by require() --deps packages this package depends on --rockspec the full path of the rockspec file --mversion the package version $ luarocks show alien version: 0.5.0-1 summary: Lua->C FFI detailed: Alien lets a Lua application call load dynamic libraries and call C functions in a portable way, using libffi. homepage: http://alien.luaforge.net directory: /usr/local/lib/luarocks/rocks/alien/0.5.0-1 modules: alien.struct alien.core alien $ luarocks show alien --home http://alien.luaforge.net $ ls $(luarocks show alien --dir) alien-0.5.0-1.rockspec bin doc rock_manifest samples tests The description information is read from the rockspec, and the module information is extracted from the manifest. There are a number of other flags that could be useful - like 'license' (I always forget this ;)). The documentation directory for a package is conventionally PACKAGE_DIR/doc and that could definitely be useful, especially if we try to be a little clever and find a suitable index.html or readme.txt, etc. We could also make 'luarocks show --info' present a useful summary of the important global configuration parameters, like where the configuration files are currently living. I am unsure how to handle the multiple-version-and-repo issues: it picks the latest version from the last repo, which is _generally_ what you want. Here some guidance is needed... steve d. [1] To install this (or any new command) put it in the luarocks module directory (that is, something like /usr/local/share/lua/5.1/luarocks or c:\Program Files\Lua\5.1\lua\luarocks). For Unix, edit the luarocks command, which is an executable Lua script and add commands.show = require("luarocks.show") to the end of the commands list. On Windows, do the same but with luarocks.lua (which for LfW at least sits in the Lua executable directory
show.lua
