\pdfcatalog broken in MkIV

\pdfcatalog broken in MkIV

[Andreas Schneider]

Hello,

as suggested in the thread about PDF Page Labels, \pdfcatalog can be used to 
manually modify the PDF Stream. However it seems that this does not 
currently work in MkIV (from the minimals, beta branch). In MkII it does 
exactly as I though (the resulting PDF contains a Catalog section with the 
content I passed to \pdfcatalog). In the PDF produced by MkIV however no 
Catalog can be found.

Best Regards,
Andreas.

*bump*

Any chance of having a fix for this? An example can be found here:
http://archive.contextgarden.net/message/20081016.174838.bff55fc9.en.html
texexec/MKII produces a PDF with said catalog, luatex/MKIV doesn't.

Thanks in advance,
Andreas.

The \pdfcatalog primitive is not broken, it's simply not present in mkiv 
where we have a rather strict control over access to pdf resources.

Anyhow, i'll add an option to the upcoming beta (normally I only do such 
weird features in paid projects). The thing is that it has to be hooked 
into the regular mechanisms properly (numbering, conversion) and the 
code in the mail you refer to is not ok (as it's hardcoded).

Concerning your example, control over numbers happens this way:

\definestructureconversionset[frontpart:pagenumber][][romannumerals]
\definestructureconversionset[bodypart:pagenumber] [][numbers]

\setupuserpagenumber[way=byblock]
\setupuserpagenumber[numberconversionset=pagenumber]

\starttext

\startfrontmatter
     \completecontent[interaction=all]
     \chapter{Preface}
     \dorecurse{10}{\input zapf\par}
\stopfrontmatter

\startbodymatter
     \chapter{Test}      \dorecurse{15}{\input tufte\par}
     \chapter{TestAgain} \dorecurse{15}{\input ward\par}
\stopbodymatter

\startbackmatter
     Index maybe.
\stopbackmatter

Indeed, it is a workaround. But I think it's not bad in this case. As you 
said, it's a "weird feature" and probably one that isn't used by many 
people. Having \pdfcatalog allows for that workaround to be used without you 
having to implement anything specific for the suggested feature (pdf page 
labels). It it's too much trouble or against the design principals of MkIV, 
then please don't waste any time on it. The job you do with ConTeXt is 
incredible and it is a very good environment to work in/with. This feature 
is just a very very small cosmetic change to the final document, not a 
showstopper or anything - I can live without it (but it would be a nice-to-
have).

Best Regards,
Andreas.
