Get the Lua decompiler and make the Lua file a .lur file.
You mean the compiler... the compiler compiles a LUA file, for Bully the compiled files are LUR files. The decompiler is what takes the compiled files to LUA files... or tries to at least.
Well, yeah you pretty much just compile the LUA file once you're done with the LUA file, then you get your compiled file (A .lur for Bully) and then it's up to you where you want to keep your source after that, or discard it if you don't plan to make any more edits to it.
It sounded like a bit of an odd question to me honestly, but I hope my answer helped a bit.
