Introduction In this post I’ll give a very simple example of how you can use LuaTeX’s node machinery to create graphics. The example really is very basic but, hopefully, indicates what could be achieved with more sophisticated code. I hope…
LuaTeX provides a very interesting facility called “callbacks”. A callback is a Lua function that you provide and which LuaTeX will call at certain times during the course of processing your document. LuaTeX defines a number of callback opportunities which…
Update: Google viewer stopped working so I deleted it. Just download the PowerPoint if interested. Here is an extract from a recent PowerPoint presentation. Posting this is an experiment to see if the Google Docs viewer will render PowerPoint .pptx…
Introduction LuaTeX provides access to the deepest internal structures of the TeX engine: nodes, the fundamental building blocks created and assembled by the typesetting engine. I won’t try to explain nodes in detail here but instead refer you to an…
The following example may help to understand a little more about \directlua{} expansion. \documentclass[11pt,twoside]{article} \begin{document} \def\xx{Hello} \def\yy{(} \def\zz{)} \newcommand{\hellofromTeX}[1]{ \directlua{ function Hello(str) tex.print(str) end \xx\yy#1\zz }} \hellofromTeX{“Hello World”} \end{document} Here’s how it works. Code within \directlua{} is expanded according…
One feature of LuaTeX which might prove useful in some circumstances is its ability to connect to networks through TCP This facility is due to the luasocket TCP/IP networking library which is built into the executable. In addition to the…
