Oh, another thing I've learned from your example us that \starttext ...\stoptext can be nested... ________________________________________ Von: Hans Hagen Gesendet: Samstag, 27.

Thanks for this as well, Hans. Looks promising. So, this is to select pages or page-ranges for processing?

I could also treat them as two individual books, but then I'd have to get the

last page number of volume 1 in volume 2. In the early days of context (more than 2 decades ago) we had a printer where we could inject from different trays and that is why we have a feature in context to mark pages (so that directives for printers could be inserted). This feature survived / evolved into marked pages.

You can do this (oeps.tex):

\starttext

\chapter[one]{One}

\markpage[first] test \page test \page \markpage[second] test \page

\chapter[two]{Two}

test \page \markpage[fourth] test

\page

% \doifelsemarkedpage{second}{YES}{NO} % \doifelsemarkedpage{fourth}{YES}{NO}

% \page

% \doifelsemarkedpage{second}{YES}{NO} % \doifelsemarkedpage{fourth}{YES}{NO}

\stoptext

So, I was wondering if we can expose that differently.

...

context --pages oeps mtx-context | page : 0001 first mtx-context | page : 0003 second mtx-context | page : 0005 fourth

...

context --pages --page=second oeps mtx-context | page : 0003 second

...

context --pages --page=second,fourth oeps mtx-context | page : 0003 second mtx-context | page : 0005 fourth

But, as you're talking chapters, a variants (with less overhead) is:

...

context --pages --list=one,two oeps mtx-context | list : 0001 one mtx-context | list : 0004 two

Which of course assumes that you have a reference for the chapters.

This --pages feature is in the latest upload.

i could add something to the select style but i guess then there is no uniformity in how users do this

Many thanks for the new stuff, Hans. This could be an approach: \starttext \completecontent \dorecurse{10} {\startchapter\markpage[start-\recurselevel] \dorecurse{\randomnumber{0}{1000}} {\input knuth\par} \markpage[stop-\recurselevel]\stopchapter} \stoptext "start-" and "stop-" could define page ranges when the same identifier is used. The select style could generate from start-identifier and stop-identifier, the result "identifier.pdf". I think this is a simple approach. Many thanks for your help, Pablo -- http://www.ousia.tk

and --pages=whatever,moreover will give you the info you need to call context --extra=copy or whatever with the right arguments

Hans, real-world needs may be complex, such as in the following sample: \starttext \completecontent \dorecurse{3} {\startpart \edef\pn{\recurselevel} \dorecurse{30} {\startchapter\markpage[start-\pn.\recurselevel] \dorecurse{\randomnumber{0}{30}} {\input knuth\par} \markpage[stop-\pn.\recurselevel]\stopchapter} \stoppart} \stoptext This generates a document to be split in 90 individual documents. I cannot even think in specifying them manually. It would be very useful to have something similar to: context --extra=select --selection=pages oeps --once --autopdf I hope my explanation is clearer now.
