This is likely going to break all kinds of stuff, because not everything
in \startscope[...] can always be expanded. Also the brackets are
optional in the original definition of \startscope, so a \dosingleempty
would at least be in order:
\appendtoks
\let\normaltikzstartscope\startscope
\def\dostartscope[#1]%
{\normalexpanded
{\noexpand\normaltikzstartscope[#1]}}%
\def\startscope{\dosingleempty\dostartscope}%
\to \everyinsidetikzpicture
In fact, pgfkeys has a handler for expanding keys before doing
assignment to work around exactly these situations:
\startscope[shift/.expanded={\p}]
No redefinition needed.
We could also do \edef or \romannumeral expansion in the shift key in
TikZ, but I'm not sure whether that would break someone's code.

True, but then there is still the problem with the number of
expansions. With a nested \directlua I always need at least two steps
to get the result from Lua.
\directlua{
function TestCmd()
tex.print("\string\\numexpr 17\string\\relax")
end
lua.get_functions_table()[999] = TestCmd
}
\let\:\expandafter % I'm lazy
\tt
\directlua{token.set_lua("test", 999)}
\:\def\:\x\:{\test}\meaning\x % macro:->\numexpr 17\relax
\protected\def\test{\directlua{TestCmd()}}
\:\def\:\x\:{\test}\meaning\x\par % macro:->\directlua {TestCmd()}
\:\:\:\def\:\:\:\x\:\:\:{\test}\meaning\x % macro:->\numexpr 17\relax
\bye
How much do you think would break if protected luacall were treated
like protected macros after \the in the engine?
That would probably need an extra branch in the switch(cur_cmd) in
scan_something_internal. Currently protected luacall just goes to the
default branch (You can't use ...).

Thanks, this is indeed the workaround that I currently use. However,
the downside is that this has to tokenize the contents of \directlua
every time (and is therefore susceptible to surrounding \catcode
shenanigans) and it expands in at minimum two steps, whereas a luacall
always expands in a single step. But I guess that's what I will have to
live with.

Thanks for pointing out my mistake. Your example works fine but now the
luacall is no longer protected and will therefore fully expand in
\edef. So do I understand this correctly that there is no way to make
the second \the\test work?
\directlua{
lua.get_functions_table()[999] = function()
tex.pri
nt("\string\\numexpr 17\string\\relax")
end
}
\tt
\directlua{token.set_lua("test", 999)}
\meaning\test\par % expandable luacall 999
\edef\x{\test}\meaning\x\par % macro:->\numexpr 17\relax
\the\test % 17
\directlua{token.set_lua("test", 999, "protected")}
\meaning\test\par % luacall 999
\edef\x{\test}\meaning\x\par % macro:->\test
\the\test % ! You can't use `luacall 999' after \the.

[NTG-context] protected macro vs protected luacall
Dear list,
I have noticed a somewhat strange difference between protected macros
and protected luacalls, namely that the latter cannot be expanded by
\the. In the example below I define a Lua function that prints
\numexpr 17\relax to the token stream and I call it once from a
protected TeX macro wrapping \directlua and once from a protected
luacall registered with token.set_lua.
\directlua{
userdata = userdata or {}
function userdata.test()
tex.print("\string\\numexpr 17\string\\relax")
end
}
\tt
\protected\def\test{\directlua{userdata.test()}}
\meaning\test\par
\edef\x{\test}\meaning\x\par
\the\test
\directlua{
local t = lua.get_functions_table()
t[\string#t + 1] = userdata.test
token.set_lua("test", userdata.test, \string#t, "protected")
}
\meaning\test\par
\edef\x{\test}\meaning\x\par
\the\test
\bye
However, the second \the\test fails with the following error:
! You can't use `luacall 0' after \the.
l.21 \the\test
Is this asymmetry between luacalls and regular macros intended? Is
there a workaround where I can have a luacall that doesn't expand
inside of \edef but still expands after \the?

That's most likely due to
https://github.com/pgf-tikz/pgf/issues/1062
https://github.com/pgf-tikz/pgf/pull/1073
but this MWE
\catcode`\@=11
\begingroup
\lccode`\~=`\"
\lowercase{\endgroup
\def\pgfmath@catcodes{%
\catcode`\==12 %
\catcode`\,=12 %
\catcode`\|=12 %
\catcode`\&=12 %
\let~\pgfmath@char@quote

{\pgfmath@catcodes "}

works in Knuth TeX, so it's likely not our fault.

I do not claim that this is the cleanest way. Probably it's better to
define a separate font feature for microtypography rather than
overwriting the default set, but this definitely works:
\definefontfeature[default][default]
[protrusion=quality,
expansion=quality]
\setupbodyfont[modern] % or whatever
\setupalign[hz,hanging]
Unfortunately the global alignment settings do not propagate into
certain structures. For example itemizations, captions, and
bibliographies just reset it and need special treatment:
\setupitemize[each][align={hz,hanging}]
\setupbtxlist[align={hz,hanging,tolerant}]
\setupcaption[figure][align={justified,hz,hanging}]
I think captions are not justified by default, so that might or might
not matter to you. Bibliographies are usually full or names and
academic words that do not hyphenate well, so adding tolerant relaxes
that a little bit.

Yes, there would have to be a pgfsys-luametatex.def and some detection code to switch the driver appropriately but that latter part is easy. I'm not too sure what is needed for the former though for LMTX. When I last looked at it about a year ago it was completely unusable with the LuaTeX driver because position tracking primitives were removed (\pdflastxpos, \pdflastypos) and box keywords had changed (\hbox dir TRT). Some catcode trickery in pgfplots also had stopped working (https://github.com/pgf-tikz/pgfplots/pull/353). As Hans mentioned in another message, the PDF resource management has changed (if I understand it correctly), so things like shadings and patterns would have to be adjusted.

You can immediately forget about that, because in the past Lua has switched the random number generator (RNG) between releases and also uses a different RNG depending on the operating system. In general it is a really bad idea to depend on the exact sequence of random numbers. As an alternative you can just pregenerate a list of random numbers and copy that to other documents.
