Re: [NTG-context] Install Tikz in LMTX tree

Thanks to Hans Hagen. \newcount\eTeXversion \eTeXversion = 2000 \newcount\eTeXrevision \eTeXrevision = 0020 In the top of my tex file fixed the problem. Jorge

There are still people trying to run TikZ on plain TeX with the Knuth engine: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=920368

hm, so you can't actually use etex goodies unless you emulate them

\newcount\eTeXversion \eTeXversion = 2000 \newcount\eTeXrevision \eTeXrevision = 0020 Hm, I need something that *all* eTeX engines provide that I can check. And these seem to have met that requirement. I really don't want to write a huge cascade of if-s to test for different engines.

I'll add dummies then but be aware that you actually should test for the primitives that you expect because I'm not even sure if luatex bumped the number. As you mention "all" it means that you expect differences because "all" implies differences here. What if someone runs a very old (experimental) etex.

(\scantokens, \readline, \detokenize, \savingvdiscards are likely to be untouched .. it depends on what primitives you expect to use)
