While this compiles the three fonts always show the font that is
active before the function starts to execute.
So is there a way to select one of the three predefined font families
*from within Lua* so subsequent statements in the same Lua chunk see
the results?
I'm not sure if this thread belongs to this list as it relates more to
a macro package than to luatex
I see that - by now. Originally I thought I was looking for the right
incantation to ask Lua for the relevant information. Actually I still
think it would be good if it were available as some property in the font
tables.
but anyhow, you can do something like this (untested):
\begingroup
\rmfamily \edef\rmfamilyid{\fontid\font}%
\ssfamily \edef\ssfamilyid{\fontid\font}%
\ttfamily \edef\ttfamilyid{\fontid\font}%
\directlua{
myfonts = { }
myfonts.rm =
fonts.hashes.identifiers[\rmfamilyid].shared.rawdata.metadata['familyname']
myfonts.sf =
fonts.hashes.identifiers[\ssfamilyid].shared.rawdata.metadata['familyname']
myfonts.tt =
fonts.hashes.identifiers[\ttfamilyid].shared.rawdata.metadata['familyname']
print("")
print('Main font: '..myfonts.rm)
print('Sans font: '..myfonts.sf)
print('Mono font: '..myfonts.tt)
}%
\endgroup
or just
\begingroup
\rmfamily \edef\rmfamilyid{\fontid\font}%
\ssfamily \edef\ssfamilyid{\fontid\font}%
\ttfamily \edef\ttfamilyid{\fontid\font}%
\directlua{
print('Main font:
'..fonts.hashes.identifiers[\rmfamilyid].shared.rawdata.metadata['familyname'])
print('Sans font:
'..fonts.hashes.identifiers[\ssfamilyid].shared.rawdata.metadata['familyname'])
print('Mono font:
'..fonts.hashes.identifiers[\ttfamilyid].shared.rawdata.metadata['familyname'])
}%
\endgroup
Thank you, this finally made it to a working state. Instead of the print
statements I set these values to entries in a table which I can then
read in the Lua part.
Thank you to all contributors to this thread.
Best
