{Patrick Gundlach} {News from boxes and glue: How do the \TeX\ algorithms help in~developing a new typesetting engine?} {In this presentation I will talk about the experience of the last two years with boxes and glue. The library has not yet reached its final state, but a~lot has already been typeset with it. I will show what kind of experiences I have made with the \TeX\ algorithms, which data structures are suitable for text typesetting and how \PDF\ specialties like interaction and accessibility can be integrated. About boxes and glue: boxes and glue is a library written in the Go programming language that includes many of \TeX's algorithms, such as the optimum fit paragraph breaking algorithm, the hyphenation algorithm, and the basic structure with nodes and node lists to assemble boxes. It was originally written as a replacement for Lua\TeX\ to create documents with the speedata Publisher.}
