Hi, Recently i've started looking into Lua, a language meant for embedding in programs. It has a small footprint, and by reading themanukl i get the impression that it's a pretty well designed and clever language. So (after playing with lua and scite, which has it embedded) i started wondering about including lua in pdftex. Of course i'm dependent on others but i'm curious abotu wat members of this list think of it. It has quite a clever function model. Especially because it has a small footprint (some 100-150 k) it would add a lot to pdftex but at little cost. think of on the one hand: \dimen0=\lua{tex.todimen(tex.thedimen(0)+tex.thedimen(2)} kind of things, or \setbox2=\hbox to \lua{tex.todimen(somevar)} {\lua{tex.text("abcde")}} and alike. Of course the interface is to be determined, but a startingpoint can be access to box dimensions and registers and the ability to pipe text (strings) back into teh tex inpt stream. whatdoyouthink ...
