Returns the package path currently configured for this installation
of LuaRocks, formatted as shell commands to update LUA_PATH and LUA_CPATH.
--no-bin Do not export the PATH variable
--append Appends the paths to the existing paths. Default is to prefix
the LR paths to the existing paths.
--lr-path Exports the Lua path (not formatted as shell command)
--lr-cpath Exports the Lua cpath (not formatted as shell command)
--lr-bin Exports the system path (not formatted as shell command)
On Unix systems, you may run:
eval `luarocks path`
And on Windows:
luarocks path > "%temp%\_lrp.bat" && call "%temp%\_lrp.bat" && del "%temp%\_lrp.bat"
