For Minetest 5.4 and above

How do I install this?

A probably buggy inspector for flow GUIs to help with debugging layouting.


  • /inspector: Toggles the inspector for all flow forms opened with form:show().

Hot reload

When the "hot reload" button is pressed, the server reloads the file containing the function passed to flow.make_gui. This file must have exactly one flow.make_gui call for hot reload to work. Existing values in ctx are preserved when hot reloading.

The file containing flow.make_gui shouldn't contain any registrations (for example minetest.register_globalstep) as it may result in them being registered multiple times.

Open debug shell

If you're running Minetest in a terminal, an "open debug shell" button will be shown which will call debug.debug() (or dbg.dd() if the dbg mod is installed) when pressed. player, ctx, and name variables are set when the debug shell is open.


  • flow_inspector.enable(player): Enables the inspector.
  • flow_inspector.disable(player): Disables the inspector.
  • flow_inspector.inspect(player, form): Opens the inspector for form.



Do you recommend this mod?

  • Exactly what I needed!

    Eliminates countless questionable debugging strategies I've resorted to by doing things the right way. (just don't look at the source for this mod too closely - there's some hacks there for sure lol)
