Dear list,
I'm struggling to output bibliography entries into lua for string
modification (like making a particular author name bold). In effect, I
just need something like the following:
\starttexdefinition btx:customauthor
\startluacode
local text = context.btxflush('author')
-- tex.sprint(text) -- fails because text remains nil
\stopluacode
\stoptexdefinition
It's clear that btxflux is the wrong function for this as it writes the
contents to file rather than returning a variable in lua... Is there a
way to directly access what btxflush is writing through the publications
table or other means? I've gone over the source code but I can't
decipher what btxflush is actually doing.
This is not for the fainthearted so here we go
\startluacode
function document.MyBoldPub(set,tag)
-- local a = publications.getfield(set,tag,"author")
-- inspect(a)
-- local c = publications.getcasted(set,tag,"author")
-- inspect(c)
if c[1].surnames[1] == "Myname" then
context.bold(function()
context.btxflush('author')
end )
else
context.btxflush('author')
end
end
\stopluacode
\starttexdefinition btx:customauthor
\ctxluacode{document.MyBoldPub("\currentbtxdataset","\currentbtxtag")}
\stoptexdefinition
try to avoid tex.print cum suis, use the proper context.* interface instead
Thanks,
Stan
