TeX markup in \setupinteraction for PDF metadata fields

TeX markup in \setupinteraction for PDF metadata fields

[Kate F]

Hi,

Is it possible to have TeX markup executed in the text fields for
\setupinteraction?
I would like to do something like:

\definemarking[xyz]
\marking[xyz]{Hello}
\setupinteraction[state=start]
\setupinteraction[title={\getmarking[xyz][current]}]
\setupinteraction[author={\getmarking[xyz][current]}]
\starttext
xyz=\getmarking[xyz][current]
\stoptext

But my generated PDF has literally "\getmarking[xyz][current]}" for
the title and author.

Thanks,

-- 
Kate

Are you sure you want to use marks to store text because the mechanism
works only in headers and footers.

I don't know, actually. In this case these are values which remain
constant throughout the document. So all I'm after here is a mechanism
for storing variables by name. Is there something more appropriate to
use for those kind of variables?

I didn't know markings only exist in headers and footers! Thanks.

You can use the \setvariables command the set the values and access them 
with \getvariables:

\setvariables
   [information]
   [title=Document title,
    author=Author name]

\setupinteraction
   [ state=start,
     title=\getvariable{information}{title},
    author=\getvariable{information}{title}]

\starttext
\unknown
\stoptext


There is also the \setupdocument command (a simple wrapper for the 
\setvariables command)
which uses predefined keywords to set fields in the pdf file. You can 
access the values from
\setupdocument command in your document with \documentvariable{<KEY>}.

\setupdocument
   [ metadata:title=Document title,
    metadata:author=Author name]

\setupinteraction[state=start]

\starttext
\unknown
\stoptext

How does this play with
\startdocument
  [title=Document title,
   author=Me]

Here, I learn about metadata:title=
which suggests that I could do without
\setupinteraction
  [state=start,
   title={\getvariable{document}{title}},
   author={\getvariable{document}{author}}]

But, if I want to use the title etc. in the title page, should I do
something like:

\starttitlepagemakeup
  \getvariable{document}{metadata:title}
\stoptitlepagemakeup

Thanks

Alan

It doesn’t matter if you set the values with \setupdocument or 
\startdocument.

You can use \documentvariable{...} to access the values.

It depends, when you want the title in the pdf without a manual setting
with \setupinteraction you can use the value of “metadata:title” in your
document.

Thanks! I remembered about \setvariables just after asking. I think
that suits my situation more than \setupdocument, since I'm doing this
from handling various different kinds of XML, and this way I can keep
the call to \setupinteraction shared between all of them.

Thanks, again, these are useful pointers.
In conclusion, good practice could be (but would this work?):

\startdocument
  [title=My title,
   metadata:title=\documentvariable{title},
   author=Me,
   metadata:author=\documentvariable{author}]
...
\stopdocument

I would separate both settings and put \setupdocument somewhere in the 
preamble.

\setupdocument
   [metadata:title=\documentvariable{title},
    metadata:author=\documentvariable{author}]

\startdocument
   [title=My title,
    author=Me]
...
\stopdocument
