Write to tuc file

[-- Attachment #1.1: Type: text/plain, Size: 226 bytes --]

Hi,
I want to split a PDF produced by context automatically at certain points. I was thinking I could add information about the desired breakpoints to the tuc file, but I don't know how you do this. Any hints?
Best,
Denis

Can you define "split"

Re: Write to tuc file

It's a book that will be published in two volumes, continually paginated.
In the end I need two pdf files, but I thought it might be easier to treat them as one volume and just split the files with some external tool afterwards.

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.

On the console you see the pagenumbers right? What you need is the 
realpage. You could actually do something:

\dorecurse{10}{\samplefile{tufte}\page}
\appendetoks
     \writestatus{!!!!!}{}
     \writestatus{!!!!!}{SPLIT HERE: \the\realpageno}
     \writestatus{!!!!!}{}
\to \everystoptext
\dorecurse{10}{\samplefile{tufte}\page}

and then use this number in:

context --extra=select --selection=1:4    oeps.pdf --once --autopdf
context --extra=select --selection=5:9999 oeps.pdf --once --autopdf

(We can actually relate tags to pages so maybe I will make something to 
  pick that up from the tuc file.)

Thanks, that's helpful. So to automate this, I'll just need to get the pagenumbers from the log file. I'll give it a try.

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.

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

assuming that you have either marked pages or proper refs for chapters 
you can use the reported values and feed them into whatever

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

\startchapter[reference=whatever,title=foo]
\stopchapter
\startchapter[reference=moreover,title=oof]
\stopchapter

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.

Many thanks for your help,

Pablo
