Hi list,
How do I replace the "???" in
\def\FooBarPlic{Ploc}
\directlua{
% ???
}
by some Lua code that lists all the macros that have "Bar"
in their names?
I've spent the last hours trying to fix the answers that I
found on Google, StackExchange, StackOverflow, etc, but they
all (?) start with this,
cmds = token.commands()
call_cmd = token.command_id("call")
that doesn't look very promising, because cmds is a list
with just 156 elements... I also tried to find hints in the
LuaTeX Reference Manual, and I tried to read some parts of
the files in source/texk/web2c/luatexdir/ that mentioned
"get_macro" and "def_cmd", but... I'm lost.
Is there something obvious that I am missing?
Help, anyone?

Now let me explain why I want this. I am the author of this
package, that has very few users...

In my presentation about it at the TUG 2018 meeting I
mentioned a REPL,
https://anggtwu.net/dednat6/tug-slides.pdf#page=21
that I rewrote several times since then.
I am now trying to understand some parts of pgfkeys that are
not well documented, and I thought that it could be nice,
fun, good karma, etc, to explore how those parts work by
inspecting pgfkeys's data structures from a Lua REPL, in
addition to using the "official" debugging tools that are
mentioned in the section "87. Key Management" of the PGF
manual. More concretely, in:
\documentclass{article}
\usepackage{pgfkeys}
\begin{document}
\pgfkeys{/FooBarPlic/.code=Ploc}
\pgfkeys{/FooBarPlic}
% Run the REPL here
\end{document}
I am trying to use the REPL to list all the macros/control
sequences that contain "FooBarPlic" in their names...
The current code can be inspected and tested with these
commands - but I recommend waiting a few more days:
rm -rfv /tmp/2026luatex-test.zip
rm -rfv /tmp/edrx-latex/
cd /tmp/
wget https://anggtwu.net/LATEX/2026luatex-test.zip
mkdir /tmp/edrx-latex/
unzip -d /tmp/edrx-latex/ /tmp/2026luatex-test.zip
cd /tmp/edrx-latex/
export RUNREPL3=yes
lualatex 2026luatex-test.tex
Cheers, and thanks in advance!
