You don't need to write your own console as you may want to start with one of the existing ones. RemDebug has already been suggested; I have been developing MobDebug, which is a debugger based on RemDebug, but with a host of new features and bug fixes. The detailed list of the changes is in the README.

Enabling debugging in your script may be as simple as adding require('mobdebug').start() (if you are running your app and the debugger server on the same machine). This should try to connect to the debugger listening on a default port on localhost. You can use a command-line interface included in MobDebug, or you can use a ZeroBrane Studio, which is a Lua IDE that integrates with MobDebug to provide debugging capabilities. The IDE supports debugging for Love2d, Moai, and other Lua engines and may well work for your set up too.
