RE: A Lua script and a Bash script in one file

["Thijs Schreijer" <thijs@...>]

If using a variable, luafile in this case, then you should add setlocal to
prevent polluting globals

::lua:: --[[
@setlocal 
@set luafile=%0
@if exist %0.bat set luafile=%0.bat
@lua52.exe %luafile% %*
@exit /b %ERRORLEVEL%
]]
--assert(false)
print 'This is Lua script'
os.exit(2)
