\documentvariable (used in environment)

\documentvariable (used in environment)

[Alan Braslau]

Hello,

I have put the following in an environment

\startenvironment MYENVIRONMENT

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

\stopenvironment




and correct use would be

\environment MYENVIRONMENT

\startdocument [title={My title}]

\stopdocument


because, of course, the environment contains more than \setupdocument 
such as font loading that should be done before the \startdocument.

The metadata does not get set properly, having to do with expansion or 
other notions of TeX that I never seem to get right. What might be the 
proper way of handling this?

Thank you

Alan

What exactly doesn't work and do you get the same problems when you set 
the values in the following minimal example (everything has to be in the 
same file).

%%%% begin example
\setupdocument
   [metadata:title={\documentvariable{title}},
    metadata:subtitle={\documentvariable{subtitle}},
    metadata:author={\documentvariable{author}},
    metadata:keywords={\documentvariable{keywords}}]

\startdocument [title={My title}]
\input knuth
\stopdocument
%%%% end example

Thank you, Wolfgang.

The above example does work. It fails to set the metadata if one moves 
the \setupdocument to an environment file. As you write, "everything has 
to be in the same file". This is my question, how to set these using an 
environment file, thus NOT the same file as the \startdocument in a 
project structure.

The requirement was only necessary for the example to check if the 
metadata end up in the PDF file. You could have a environment file for 
\setupdocument but the goal here was to check the resulting metadata in 
the PDF.

The problem is something in your environment/style file which causes a 
problem with the \setupdocument setup. What you should do to find the 
sulprit is:

1. Make a copy of your document
2. Remove all text between \startdocument and \stopdocument and add some 
dummy text (like in my example) to ensure ConTeXt produces a PDF
3. Remove setups from your environment (but keep the \setupdocument 
setup) file until the metadata appears in the PDF

A typical case if something in an environment doesn’t work, but in a single file: Are there modes involved? Maybe your \setupdocument is within a \startmode ... \stopmode that doesn’t get activated.

Re: \documentvariable (used in environment)

[Alan Braslau]

Thank you all.

No modes, no funniness in the environment file.

The test case works (Acroread/properties shows the Title, Author, 
Subject, and Keywords fields). However, my real case does get the other 
fields (Author, Subject, and Keywords) but contains in the Title field 
the filename (without the .tex extension) of the main file (and 
filename.tex under File).

I'll chase it down...
