gives object number 7 written in the PDF file, but the
object that contains the _real_ data stream is object 6, not 7:
6 0 obj
/Length 20
stream
Das ist Testdatei 1
endstream
endobj
7 0 obj
/Type /Filespec /F (test1.txt) /EF /F 6 0 R
endobj
thus, in order to get the correct obj number for pdftosrc one
need the number of the stream-object.
hm, pdftosrc should probably accept both as valid numbers (i.e. in case of
no 7 resolve it to 6), so if there's someone out there willing to patch ...
another thing that might be useful is that \PDFattachmentnumber
should read the attachment name as argument and return the obj-number.
the above symbol could then be defined as:
\definesymbol
[ObjectNumber]
[object number \PDFattachmentnumber[\currentattachment]]
_and_ one can use it inside the text:
\starttext
This PDF-document has the file test1.txt attached. Users of pdftosrc
can extract the PDF-object \PDFattachmentnumber[whatever] to
get the file.
\stoptext
this is kind of tricky, since we're never sure if forward or backward
referencing takes place (apart form the fact that this kind of trickery can
seldom b eimplemented in a clean way). Anyhow, since i happen to be doing
things with attachments currently you're lucky; i made you:
\starttext
\definesymbol
[ObjectNumber]
% [object number {\PDFattachmentnumber[xx]}]
[object number \PDFattachmentnumber]
\useattachment[test][xx][test.tex]
\setupattachments[symbol=ObjectNumber]
\attachment[test]
\stoptext
(in case of just two args, i.e. no [xx], you need to feed the filename,
i.e. test.txt)
I'll send you the patched spec file (keep in mind that this
\PDFattachmentnumber is some driver functionality, and not something of teh
core).

Wouldn't it be better to bring them together in one user interface and make the pdf-based layering an option: PDF layers (officially optional content groups) have not much to do with ConTeXt layers. In PDF 1.5 (Acrobat 6) there's a new feature that allows hiding of some objects, like the layers palette in DTP or CAD software. But PDF layers are more: they can be connected with special view sizes (increase detail level while zooming in) and much more. Think of - different language versions in the same document - b/w and color versions in the same document - additional content that is only visible with a password - architectural drawings: floors or pipes, wires, walls, furniture ... (one layer for each craftsman) - other CAD stuff - higher detail level with zoom (I saw this with a city map) - and much more... PDF guru Stephan Jaeggi said, the possibilities of this new technique were overwhelming as a Adobe developer showed him some details. Think further of layers combined with transparency options -- creative possibilities like in Photoshop! (Don't know if this really works, but I guess.) Besides AutoCAD there's no commercial software that can write such layers -- ConTeXt seems to be ahead the whole industry!
