This package replicates the functionality of the lua alias inside its own UserWindow.
It comes with a single alias, replet, which opens the REPLet console. From there, you can execute arbitrary Lua code and see the results in the console.
Once you have the console open, type usage within the console to see extra commands that REPLet comes with, in addition to executing code.
By default, adds recho(msg), rcecho(msg) etc to allow for easy c/d/h/echoing directly to the console. Also adds rdisplay, which works like display() but prints to the REPLet console. If this covers over functions you already have and want to use in the console, use addEchos false in the REPLet console's command line.
REPL is an acronym which stands for Read Execute Print Loop and is the term for interactive code runners like this. So I squashed it together with Mudlet to make REPLet.
