Re: [luatex] lua equivalent of vbox...ht

Another related question:

what would be the lua equivalent of
\setbox0\vbox{hello world}
\the\ht0

? That is, what would I write inside \directlua{ ... } to get the same
effect?

Is it even possible to write this in Lua? I need to invoke the line  
breaking algorithm at some time, how do I do this in Lua?
