Split up PDF a certain
by Denis Maier 15 May '19

15 May '19

Hi, is there a way to split up a PDF a certain points, e.g. at every \startsection? (I am thinking of a way to produce both one PDF for a complete journal issue and for each individual articles. Or should I better use an external tool to post-process the resulting PDF?) Best, Denis

Compiling multiple files without master document
by Denis Maier 15 May '19

15 May '19

Hi, Currently it is possible to process a file with an external environment file specified via the command line. ``` context file --environment=mydefs ``` Very nice. Is it possible to process multiple files from the command line without a master document? Like so: ``` context file1 file2 file3 --environment=mydefs ``` Or should I just use `cat file1 file2 file3 > file` before processing? Best, Denis

Difference between the pagecolumns mechanism vs newcolumnsets/pagegrids?
by SPIT 15 May '19

15 May '19

Complete beginner with ConTeXt, just confused about the difference between the difference between mechanisms due to the similar naming? Is it just a difference in float handling?

context standalone installation broken
by mf 14 May '19

14 May '19

./first-setup.sh --engine=luatex --modules=all downloads ok, but then .../tex/setuptex gives this error: "/home/massi/context/latest/tex" is not a valid TEXROOT path. (There is no file "/home/massi/context/latest/tex/texmf/tex/plain/base/plain.tex") provide a proper tex root (like '. setuptex /something/tex') Massimiliano

\includeonly and ConTeXt components
by Denis Maier 14 May '19

14 May '19

Hi again, last question for the moment ;-) With LaTeX we can use `\includeonly` for partial compilation. The good thing is that we can still refer to labels from other files, have a complete TOC, and correct page numbers. In ConTeXt the project structure is supposed to be used for partial compilation. But it does not seem to have those features, right? Having correct page numbers across the individual components would be especially helpful. Any ways to get this? Best, Denis

Questions regarding project structure
by Denis Maier 14 May '19

14 May '19

Hi, I am just testing out the project structure. Let's suppose I have these files: - test_env.tex ``` \startenvironment * \setuphead [section] [textstyle=\bf] \stopenvironment ``` - test_project ``` \startproject * \environment test_env \product test_prod \stopproject ``` - test_prod.tex ``` \startproduct * \project test \startalignment[middle] HEY \stopalignment \component test_comp \stopproduct ``` - test_comp.tex ``` \startcomponent * \product test_prod % \project test_project % uncomment this to use the \section{Test} \input ward \stopcomponent ``` >From the documentation [https://wiki.contextgarden.net/Project_structure] I would assume two things 1. The environment should be used in the component via project=>product. 2. Everything in the product that is not in a component should be used in the component as well. Both assumptions seem not be correct. Any hints about this? Am I missing something? Am I doing something wrong? Or is there a bug somewhere? Documentation errors? Best, Denis

thumb index: \setlayer on every odd/even page?
by Henning Hraban Ramm 13 May '19

13 May '19

Hai, how must I setup layers that get repeated on every even/odd page? Or should I use \doifoddpageelse with \setlayer? Or do you have a different suggestion for thumb index “boxes”?
