This page provides some tips how to debug Impala/Thorin.

• change log level during debugging

  call thorin::Log::set_min_level(0)

• Note that you can output thorin code during debugging:

  call scope.thorin()
  call scope.write_thorin("my_file_scope.thorin")
  
  call world.thorin()
  call world.write_thorin("my_file_world.thorin")

• You can also add the following to your ~/.gdbinit file:

  define tos
    call $arg0->to_string()
  end
  document tos
    Call to_string on an object.
  end
  define wrthorin
    call $arg0.thorin()
    call $arg0.write_thorin($arg1)
  end
  document wrthorin
    Write thorin representation to the file given as argument.
  end
