full expansion in widgets

full expansion in widgets

[Pablo Rodriguez]

Hans,

I have the following sample:

    \def\hola{hola}
    \def\MyContent{B \quotation{C} \hola\ D}
    \enabledirectives[interaction.identity.preroll]
    \setupinteraction[state=start, title={\MyContent}]
    \setupinteractionscreen[option=attachment]
    \setuppapersize[A5, landscape]
    \setuppagenumbering[location=]
    \placebookmarks[chapter]
    \enabledirectives[references.bookmarks.preroll]
    \starttext
    \startchapter[title=\MyContent]
    \startbuffer[abc]
        buffer contents
    \stopbuffer
    Just an attachment.\attachment[name=buffer.txt, author={Me},
    title={\MyContent\ \input knuth}, buffer=abc]

    \setupfield [TextSetup][width=.5\textwidth, height=.5\textwidth,
         frame=off]
    \definefield [SomeField] [text] [TextSetup] [\MyContent\ \input
        knuth]
    \field[SomeField]
    \stoptext

Would it be possible to have full expansion in PDF widgets? (I mean, the
attachment fields and annotation. and the fill-in text field.)

Many thanks for your help,

Pablo

Full expansion doesn't help you here, because \input is protected (i.e. not expandable).  Either use
\normalinput or do \expandafter\relax\input knuth  (this however leaves a literal \relax in PDF
field).


\def\hola{hola}
\def\MyContent{B \quotation{C} \hola\ D}
\enabledirectives[interaction.identity.preroll]
\setupinteraction[state=start, title={\MyContent}]
\setupinteractionscreen[option=attachment]
\setuppapersize[A5, landscape]
\setuppagenumbering[location=]
\placebookmarks[chapter]
\enabledirectives[references.bookmarks.preroll]
\starttext
\startchapter[title=\MyContent]
\startbuffer[abc]
    buffer contents
\stopbuffer
Just an attachment.\attachment[name=buffer.txt, author={Me},
title={\MyContent\ \input knuth}, buffer=abc]

\setupfield
  [TextSetup]
  [width=.5\textwidth,
   height=.5\textwidth,
   frame=off]

\definefield
  [SomeField]
  [text]
  [TextSetup]
  [\MyContent\ \normalinput knuth ]

\field[SomeField]
\stoptext

Hi Henri,

many thanks for your reply.

Using \normalinput also requires complete expansion. Otherwise, I get
\TeX \ instead TEX.
