Thank you, Khaled, for this clarification. My understanding of the situation is a little different. First some background. If one wants to provide a service (to Lua scripts) then one has to write an extension (to Lua). If one want to write an application, one can go either way (either embed or extend). According to http://www.luatex.org, the "main objective is to provide an open and configurable variant of TeX while at the same time offering downward compatibility." I don't see anything here that leads them to prefer embed over extend. On the page http://www.luatex.org/roadmap/ I see "allow Lua callbacks for file searching" "Allow Lua scripts to control [...] font loading etc." and so forth. These might be situations where embed would be preferred to extend, but I'm not sure either way.

Thank you for your encouragement and interest. I really think this sort of thing is a vital part of our future (along with something better than the TeX macro language). -- Jonathan

REQ: Please tell comp.text.tex why LuaTeX chose embed rather than extend.
by Jonathan Fine 25 May '09

25 May '09

Hi This week there's been a nice discussion on comp.text.tex that started in the context of LuaTeX. It was on the difference between embedding a scripting language in an application and extending a scripting language with a module written in a compiled language. One of the best parts, in my view, was Zeljko Vrba pointing out, in effect, that Postgres both embedded scripting languages and provided an interface that allowed it to be used as an extension to a scripting language. This provides a wonderful dual example. One of the participants asked: "What was the rationale behind choosing the embed route by the LuaTeX team?" We'd be delighted if posted an answer to this question to comp.text.tex. To help you find the c.t.t discussion, here's a URL: <http://groups.google.co.uk/group/comp.text.tex/tree/browse_frm/thread/d3522…> And here's a shorter one: http://groups.google.co.uk/group/comp.text.tex/search?hl=en&group=comp.text… with best regards Jonathan
