Hi,
According to the manual (and tex.extraprimitives), \expanded is a pdfTeX
primitive. However,
% pdftex -ini '\show\expanded \end'
This is pdfTeX, Version 3.1415926-1.40.11 (TeX Live 2010) (INITEX)
restricted \write18 enabled.
\expanded=undefined.
<*> \show\expanded
\end
?
No pages of output.
Transcript written on texput.log.
Also, I can find no mention of \expanded in the pdfTeX manual. Am I missing
something?
If I remember correctly, \expanded is a pdfTeX primitive... that never
made it to pdfTeX, hence its absence in the manual.
And it's meaning is to expand completely its argument. E.g.:
\def\foo{\bar}
\def\bar{bla}
\immediate\write17{\unexpanded\expandafter{\expanded{\foo\foo}}}
prints "blabla".
Best,
Paul
