Hi
Wolfgang,
Thanks again! Indeed
\defineexpandable\authorpicture{hacker.jpg}
solves the problem in
the simplified case I was reporting.
However in the real case, the
file « hacker.jpg » is in fact a file which depends on other variables,
and when I include \defineexpandable in the \getvariable environment
then it does not work anymore: saying
\defineexpandable\authorpicture{\getvariable{talk}{picture}}
or
\defineexpandable\authorpicture{\expanded{\getvariable{talk}{picture}}}
or
\defineexpandable\authorpicture{\expandafter\getvariable{talk}{picture}}
does
not solve the problem.
Below is a minimal example showing the
issue (with what you taught me last week…).
Best regards: OK
