Basically, if you want to capture the Lua process interactively, you need to switch off buffering on stdout.

So in the SciTE that comes with LfW, the invocation for Lua is:

lua -e "io.stdout:setvbuf 'no'" "$(FileNameExt)"

Here it's done to keep stderr/stdout in sync, but this trick works fine for interactive use.
