This question is originally from the discussion under github issue CTeX-org/forum#4.

The similar problems raised by questions

are now nicely solved with the newly updated PGF 3.1, using either luatex 1.07 or 1.09 under Linux (see this issue comment) and Windows (verified by my friend). This is why the current question is tagged duplicate.

But, as stated in this issue comment and the following one, the problem (will explain latter) remains under macOS, even with PGF 3.1.

The problem fixes if I use

  • LuaTeX 1.09, or
  • LuaTeX 1.07 by luatex53 --fmt=lualatex main.tex.

Hence, so far as I know, the problem only remains with macOS, LuaTeX 1.07 (Lua 5.2.4).

A full example

\documentclass{article}
\usepackage[compat=1.1.0]{tikz-feynman}

\begin{document}
\begin{tikzpicture}
  \begin{feynman}
    \diagram [vertical'=a to b] {
      i1 [particle=\(e^{-}\)]
         -- [fermion] a
         -- [draw=none] f1 [particle=\(e^{+}\)],
      a -- [photon, edge label'=\(p\)] b,
      i2 [particle=\(e^{+}\)]
         -- [anti fermion] b
         -- [draw=none] f2 [particle=\(e^{-}\)],
    };
    \diagram* {
      (a) -- [fermion] (f2),
      (b) -- [anti fermion] (f1),
    };
  \end{feynman}
\end{tikzpicture}
\end{document}

  • I believe it is the same issue as this one. –  Dec 25 '18 at 19:39
  • @marmot You are right. I apologize for not doing enough searching before asking. – muzimuzhi Z Dec 25 '18 at 19:45
  • Now there is an answer. Of course, if it does not help you, I will be happy to retract my duplicate vote. –  Jan 01 '19 at 23:28

    @marmot With PGF 3.1, the problem is solved under Linux (verified by you here) and Windows (verified by my friend), but not macOS (double checked by my friend and myself). Hence this question is not solved for users of macOS, including myself. – muzimuzhi Z Jan 09 '19 at 02:53
  • @marmot I have edit the question to show updated info. Would this be capable of re-opening? – muzimuzhi Z Jan 09 '19 at 03:15

    I voted for reopening because the problem persists on MacOS (I explicitly confirm that). –  Jan 09 '19 at 03:16
  • @marmot I personally even do not need to draw a feynman diagram. Actually this problem is first encountered by another LaTeX user, apart from me. I pay close attention to this, partly by curiosity. The unsolved state of this question will not delay any of my working, so anyone reading this can take it easy. After all, the question itself (possibly with some mysterious "bugs") may be history after the announcement of TeX Live 2019. – muzimuzhi Z Jan 09 '19 at 03:55
  • I did not mean to say anything negative about the package. And thanks for trying to solve this. I am unfortunately clueless and hope there will be a solution. However, this is a democratic system, so we need more than one vote. And I stress that I like the fact that it is democratic, and don't like the gold badge thingy. –  Jan 09 '19 at 04:34
  • @marmot I like that fact too. – muzimuzhi Z Jan 09 '19 at 04:58
  • @HenriMenke Both focused on "flipped tikz graphing", seemingly the linked question discusses influence of different luatex versions under the same platform, but this question discusses that of different platforms with the same luatex version. But it is possible the underlying causes are the same. It may take some time to understand your answer to the linked question, since I am not a programmer. – muzimuzhi Z Jan 09 '19 at 11:42
