Support question: Lua code available as a separate package?

[pgundlach]

nodetree looks useful to me. Is the Lua code available as a separate package that gets a box as the input?

[Josef-Friedrich]

The Lua code is unfortunately very well “hidden” in the dtx markup. In my texlive installation the Lua code of the package can be found at

/usr/local/texlive/texmf-dist/tex/luatex/nodetree/nodetree.lua

If you write a little bit of boilerplate code nodetree analyzes boxes out of the box:

\setbox0\hbox{\vbox{\hbox{abc}}\vbox{x}}
\directlua{
  nodetree = require("nodetree")
  nodetree.set_default_options()
  nodetree.analyze(tex.getbox(0))
}
\bye

Thank you, I'll have a look (the output is very nice!)
