Example of using wiki markup in LaTeX documents
A simple example demonstrating how to use some wiki markup syntax in LaTeX, using wiki.sty from the nicetext bundle. Be careful — not everything works, and some commands may break! See http://mirrors.ctan.org/macros/latex/contrib/nicetext/doc/wikicheat.pdf for a cheat sheet. If you're looking for markdown, check out this example!

LuaTeX: Parsing typeset paragraphs
This example is a LuaTeX-based plain TeX project which implements a LuaTeX callback function to show the components of a typeset paragraph. It is designed to accompany a blog post and, for simplicity, it is not a full-blown “parser”—for example, it is not recursive and ignores a number of node types. However, it offers a useful starting point for anyone wishing to explore callbacks in more detail.
