lout
noun
an awkward brutish person
Twenty years ago, I wrote an #XSLT stylesheet that, given some #XML document, produces input for the #Lout formatter to generate a tree diagram of this document. You can specify an XPath expression to highlight the selected nodes. This is obviously useful for teaching, but I never got around updating it to remove the dependency on Lout, so for the last ten years, I’ve been using the same examples for which I had PDFs.
Until today!
It’s been 30 years and 1 day since #Lout was first released:

If you’ve never heard about it (likely!), Lout is a purely functional #typesetting system (think TeX/LaTeX) that offers a *lot* in one MiB!
