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

[Michael Wolf <miwo@...>]

This solution works good with different calling methods but has 2 more problems.
1) If the lua script fails the batch wont stop and will interpret each
line of the lua part.
2) The exit code of the lua script is not given back.

I have following solution which solves booth problems but does not
look very good.
Maybe someone with better batch knowledge can shorten it while
preserving all functionality.

 ::lua:: --[[
@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)
