Hi,
I'm trying to get tikz-cd to run on LMTX and some examples already
work fine, but I had a problem with text on arrows.
To reproduce:
\usemodule[tikz]
\usetikzlibrary[cd]
\starttext
\starttikzcd
A \arrow{r}{A} \NC B \NR
\stoptikzcd
\stoptext
This builds fine on MkIV from TeXLive 2022 with LuaTeX, but on LMTX I get:
system > ConTeXt ver: 2022.09.11 20:44 LMTX fmt: 2022.9.20 int: english/english
...
close source > level 2, order 63, name 'tikzlibrarycd.code.tex'
fonts > preloading latin modern fonts (second stage)
fonts > 'fallback modern-designsize rm 12pt' is loaded
tex error > tex error on line 8 in file ./tik.tex: Package pgfkeys Error: I do not know the key '/tikz/"{A}"{}' and I am going to ignore it. Perhaps you misspelled it.^^J...^^Jl.7 I think the culprit is a tikzcd arrow in cell 1-1
After a bunch of debugging, it turns out that LMTX breaks the TikZ 'quotes'
library, which works using code ala:
\def\tikz@enable@node@quotes{%
\pgfkeyssetvalue{/handlers/first char syntax/the character "}{\tikz@quote@parser}%
\let\tikz@quotes@as\tikz@node@quotes@as%
}
The last part of the /-key is derived from \meaning, but in LMTX,
\meaning" is "the character U+0022 'quotation mark'"
and thus the key cannot be found.
I have patched TikZ for now to match for this alternate string too.
But perhaps it would be better for compatibility to agree with the
original TeX \meaning strings for the 7-bit ASCII subset at least.
I found another minor nit that's not really triggering a bug but still a
difference to LuaTeX: \eTeXrevision should expand to .2, but it
expands to 2 in MkIX. There is some code out there which uses
constructions like
\number\eTeXversion\eTeXrevision
or even
\ifdim 0\XeTeXrevision pt > 0.9996pt
As LMTX doesn't care about this macro, this should be easy to adjust.
Thanks,

a bit weird way to test a key .. maybe you can compare to
\edef\ThatQuote{\meaning/}
using \ifx

too messy when want to parse

i'll add the period; btw afaikt testing for an etex version is useless
because all used engines have it and there is basically only one version
and there will be no follow ups

To follow up on this: I have upstreamed patches to tikz and tikz-cd to
use the dynamic output of \meaning instead of hardcoding.
I'm not sure who maintains the t-tikz module, but if it gets updated
at some point the fix should be in.
