Hi all,
I have a document (sort of proceedings of a meeting) which have to contain several pages, with each page dedicated to an author and a specific figure (say a photo). In mkii I used to do have a command like
\define\authorpicture{hacker.jpg}
and then use a command like:
\externalfigure[\authorpicture]
to include that figure in the text, and everythinng worked ver nicely in my big document.
Unfortunately this scheme does not work anymore in mkiv…
How can I change the following code (which works in mkii) in order to have it work in mkiv?
Thanks in advance for any help: OK
%%% begin dynamic-filename-figure.tex
\starttext
\define\authorpicture{hacker.jpg}
\placefigure[here][fig:Myfigure]{}
{\externalfigure[\authorpicture]}
\stoptext
%%% end dynamic-filename-figure.tex

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
\starttext
\startbuffer[pagetalk]
\starttabulate[|f{\bi}l|p|][before=]%
\NC Speaker \EQ \getvariable{talk}{speakerfirstname} {\sc \getvariable{talk}{speakername}}
\NC\NR
\NC Title \EQ \getvariable{talk}{title} \NC\NR
\stoptabulate
\defineexpandable\authorpicture{\getvariable{talk}{picture}}
\placefigure[here][]{}
{\externalfigure[\authorpicture]}
\page
\stopbuffer
\setvariable{talk}{set}{\getbuffer[pagetalk]}
\setvariables[talk]%
[speakername={Hacker},
title={Up to date hacking},
picture=hacker.jpg
]
\stoptext

You can put the \getvariable command in \externalfigure.
\startplacefigure[location=here]
\externalfigure[\getvariable{talk}{picture}]
\stopplacefigure

You’re missing a coma after “picture=hacker.jpg” which results in “jpeg ”
(which a space at the end) as file extension for the image.

Yes indeed this was the issue… In fact I had tested « picture={hacker.jpg} » without the comma and that one also did not work, while with a comma as in « picture={hacker.jpg}, » the filename is well understood.
Many thanks and best regards: OK
