[NTG-context] How to tell a single *.tex file to produce separate PDFs?

[Joel via ntg-context]

[-- Attachment #1.1: Type: text/plain, Size: 1219 bytes --]

I have a document that's quite long. It uses a recurse function, a bit like this:

\starttext

    \dostepwiserecurse{1}{180}{1}{%
       \input chapter\recurselevel

}
\stoptext
That produces 180  chapters of content.
Anyway, my boss is upset she has to use a table of contents to navigate to the page she wants, and so wants me to split the file into 180  separate files, which somehow is going to be easier to look at. Honestly, she probably still won't ever actually look at it, but that's her requirement.

The problem is, I've been splitting the file by using Print --> PDF and choosing a custom print range, and then saving it. If I ned to repeat that 180 times, it not only will have errors, but probably take 5-10 hours.
Is there something I can put, like \breakpdf or something that will tell it to start a new PDF file? They can be named something like file1.pdf, file2.pdf, etc.
\starttext

    \dostepwiserecurse{1}{136}{1}{%
       \input chapter\recurselevel
\breakpdf

}
\stoptext
The perhaps "obvious" answer is just make 180  *.tex files, but since the minimal example above is like 0.01% of the complexity of the real file, that isn't so easy...

what is the difference between scrolling through your single page files 
folder and scrolling through a single pdf?

How about <ctrl-f> too search in the pdf?


with mutools you can take a pdf aprt into individual pages.


$ mutool --help
usage: mutool <command> [options]
	clean	-- rewrite pdf file
	convert	-- convert document
	create	-- create pdf document
	draw	-- convert document
	trace	-- trace device calls

[Denis Maier via ntg-context]

I was going to suggest pdftk which is similar to mutools. You can get
boundaries from a the log file and then split the file using these tools.
(Search the mailing list: I think that's also something ConTeXt might be
able to do natively, but I'm not sure.)

Then, you might also consider using a product-component based solution.
You'll then be able to process each file indivdually while still having a
main file around. The page numbers in the individual file will be incorrect,
i.e. always start at 1, but for having a quick look that still might be
nice. (Hans or Wolfgang probably know if there is a way to get correct page
numbers when using components...)

Best,
Denis

You can use the pdf script file but it's slower than mutool or pdftk.

mtxrun --script pdf --split file.pdf

Where will this split the pdf? At certain headers?

Hi Joel,

I tried to recreate a document with chapters that contain a different
number of pages each:

\setuppagenumbering[alternative=doublesided]
\setuphead[chapter][reference=ch\the\numexpr\namedheadnumber{chapter}+1]
\starttext
  \dorecurse{180}{%
    \startchapter[title={Chapter \namedheadnumber{chapter}}]
      \dorecurse{\randomnumber{10}{50}}
        {\input zapf\par}
    \stopchapter}
\stoptext

The key above is setting a reference for each chapter, so that they may
be retrieved later automatically.

Then you should have the pages for any chapter from its reference with
the following command:

  context --pages=ch100 main-file.tex

But I must confess, I cannot get this working. I don’t know what I miss.

If you are on Unix, generating a bash loop would be similar to (once
your main PDF document has been generated):

  for i in {1..180}; do mutool merge -o chapter-$i.pdf main-file\
  "$(context --pages=ch$i main-file)"

But for that, you need to know first how "--pages=[reference]" may work.

Just in case it might help,

Pablo

This splits the pdf into single pages and there are no options.

Joel,

others have suggested mutool and pdftk, which could be half the solution
for you.  (I use pdftk for things like this, but I assume mutool is just as
good.  Either are far less tedious than printing to file.)

If the information of the chapter boundaries is available in the log file,
a judicious use of grep and a few lines of shell script code might do the
trick.  Alternatively, you might be able to use a tool like pdfgrep to find
the page numbers from the PDF file, and then use a few lines of shell code.

If you are a Linux or Mac user, this should be "easy enough".  I don't do
windows, but now that there is (as I understand it) a bash shell available,
you might also be able to use grep and/or pdfgrep there as well.

If the log file isn't currently sufficiently helpful, could you add
something to your "start a new chapter" command to write a comment into the
log file giving you exactly the information you need?

                                Jim

Since you’ve already got the chapter content split into separate \input files ...

At the Unix level, use the following script to run Context 180 times specifying a different output file each time:

#! /bin/bash
for i in {1..180}
do
  context \
    --arguments="ChapNo=$i" test.tex \
    --result="chapter_$i.pdf”
done

And at the Context level, test.tex is simply:

\starttext
  \input chapter\env{ChapNo}
\stoptext

 I am using Linux, so those tools are available, but Bruce's solution is working great! Just had to make tiny changes to the file.
I had no idea I could send an environment variable to ConTeXt...will be using that a lot from now! Thanks very much everyone for the help!

There is also qpdf.

However, running a shell script to run context many times is my
favorite solution.

This question brings up the topic: would it be useful to be able to do
the same within context, either using lua or TeX programming?

Hi Bruce,

I had an analogous problem a while ago, but with 7 chapter files, which I treated manually…
Your solution is a very nice one, thank you for sharing ! 

For the archives, if one wishes to have the correct chapter number in each separate PDF file, one could change the content of « test.tex » file as follows:

\starttext
\setupheadnumber[chapter][\cldcontext{\env{ChapNo}-1}]
\input chapter-\env{ChapNo}.tex
\stoptext
