executing
\IfFileExists{d:/texroot/2019/texmf-dist/fonts/opentype/public/lm/lmroman10-bold.otf}{}{}
writes an entry to .fls like:
INPUT d:/texroot/2019/texmf-dist/fonts/opentype/public/lm/lmroman10-bold.otf
that's what this code does for every used opentype font. I tried offered
fio.recordfilename(fdata.filename)
but did not see any difference in .fls

Hi All,
I'm using dirty trick to write documents used .otf files to .fls by adding code
to ...\tex\latex\fontspec\fontspec.cfg
\bgroup
\catcode`\ 10 %
\gdef\opentype@write@to@fls{%
\directlua{
local fontdata = fonts.hashes.identifiers
local done = {}
for id, fdata in pairs(fontdata) do
if fdata.filename and not done[fdata.filename] then
tex.sprint("\string\\IfFileExists{".. fdata.filename .."}{}{}")
done[fdata.filename] = ''
end
end
}}
\egroup
\AtEndDocument{\opentype@write@to@fls}
Then example:
\documentclass{article}
\usepackage{fontspec}
\begin{document}
\fontfamily{ptm}\selectfont a
\end{document}
Maybe this could be solved directly in luatex engine that all the input would
be written to .fls?
i have no clue what that code is for but if it's a trick to get something
recorded, you can probably use
fio.recordfilename(fdata.filename)
