I attached an example of what you can do with very little work. I
didn't test it since I don't have that window manager, but it should
be easy to make it run.

"hc" became a table rather than a function, and instead of calling
hc("command arg1 arg2"), you can write hc.command(arg1, arg2). If
arguments are not strings they will be converted (with tostring) prior
to os.execute invocation. I added an explicit conversion (function
"signed", feel free to use a shorter name like "S") for signed numbers
that had a plus (+) sign in your original code.
