Re: lua scripts as string within another script

[Milind Gupta <milind.gupta@...>]

Here is a sample output:

> print(string.dump(load("x=1\ny=2\nprint('hello',x,y)")))

As seen the dump contains a copy of the original string. Oliver is right it is the debugging source information. If I do print(stirng.dump(load("x=1\ny=2\nprint('hello',x,y)","string"))) then the copy of the whole string is gone just left with 'string'

Is string.dump platform dependent like the bytecode?

Thanks,

string.dump() will just give you the byte codes, not the source code. Are you sure about your code? And yes, once you have the byte code you can use it as input to load() to avoid having the source code distributed. Note, however, that byte code is NOT portable and so may not load if the target platform differs from the one on which it was compiled.
