ZeroBrane Studio supports debugging of Lua 5.4 applications in several ways:

  1. (v2.00+) A Lua 5.4 interpreter is included in ZeroBrane Studio. You can select it by going to Project | Lua Interpreter | Lua 5.4.
  2. A Lua 5.4 application can be debugged as any other application using remote debugging.

If you are using Lua 5.4 interpreter that is statically compiled on Windows, you have two options to get it working:

  1. statically compile luasocket into your application, or
  2. put lua54.dll proxy DLL into the folder with your executable to make all calls to Lua 5.4 interpreter be forwarded to your statically compiled interpreter (follow the instructions for mkforwardlib-gcc-52.lua on this page, but change the name to match lua54).

what a breath of fresh air. (doctorbling)
