XML Processing with Verbatim (VIM-Typing)
by Andreas Schneider 13 Feb '15

13 Feb '15

Hello, as a few other topics on this Mailing List already discussed, it's not (easily?) possible to use \starttyping\stoptyping within XML setups. If it was "simple" verbatim, there would be a few workarounds. However, I want to provide formatted verbatim (i.e. \startJSON \stopJSON, after having \definevimtyping[JSON][syntax=javascript]). That typing environment will be further customized (by adding text background with border, etc.). I don't see a simple way to work around this without manually typesetting the code highlighting (which I don't want. I simply want <json>{someCode}</json> inside the XML file). Is there anything I can do to make this work? Maybe with preparing a buffer? (with Lua?) Thanks in advance, for any help you can provide :-) -- Minimal Example: \usemodule[vim] \definevimtyping[JSON][syntax=javascript] \starttext \startluacode function xml.functions.processJSON(t) lxml.verbatim(t, "\\startJSON", "\\stopJSON") end \stopluacode \startbuffer[demo] <test> <description> <json>{somecode}</json> </description> </test> \stopbuffer \startxmlsetups xml:initialize \xmlsetsetup{#1}{test|description|json}{xml:*} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:test \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:description %\xmlsetsetup{xml}{json}{xml:*} \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:json \xmlfunction{#1}{processJSON} \stopxmlsetups \xmlprocessbuffer{main}{demo}{} \stoptext

\setupbackend and manual hyphenation
by Axel Kielhorn 12 Feb '15

12 Feb '15

Hi! I'm trying to use Context to export a document to epub. Following the instructions on Contextgarden everything works up to a point: When I add manual hyphenation for the word "Trennalgorithmus" and \setupbackend[export=yes,xhtml=yes] I get: lua error > error on line 1 in file /Volumes/Macintosh HD/Users/axel/Documents/Text/Dokumente_LaTeX/context/Dante 2015/Dominik Wagenführ - ePub/epub/epub_bug.tex: .../context/tex/texmf-context/tex/context/base/back-exp.lua:2516: bad argument #1 to 'utfchar' (invalid value) stack traceback: [C]: in function 'utfchar' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2516: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2687: in function 'collectresults' .../context/tex/texmf-context/tex/context/base/back-exp.lua:2752: in function 'nodes_handlers_export' [string "local nodes_handlers_cleanuppage = nodes.hand..."]:18: in function <[string "local nodes_handlers_cleanuppage = nodes.hand..."]:10> (...tail calls...) .../context/tex/texmf-context/tex/context/base/node-shp.lua:171: in function 'finalizebox' [\directlua]:1: in main chunk 1 >> % !TEX encoding = UTF-8 Unicode See attached log file.

\setupcaptions question
by joerg van den hoff 12 Feb '15

12 Feb '15

I want to use `numberstopper' for figure caption customization like so: \setupcaptions[numberstopper={:}] this works fine for the caption itself (i.e. I get, e.g. "Figure 1: caption text") _but_ references to the figure via a defined label such as [fig:example] in the body text do include the numberstopper, too, which is highly undesirable in my view, since, e.g., "... see Figure 1: for an example. ..." should rather read "... see Figure 1 for an example. ..." i.e. the numberstopper should be omitted (at least optionally) when referencing. question: how can this be achieved? thx/j

My Way Math align
by Otared Kavian 10 Feb '15

10 Feb '15

Hi Aditya, I couldn’t find your May Way about Math Align on the wiki: actually I wanted to give the URL to Joerg van den Hoff who was asking a question about \cases, but with Google I found only a version going back to August 2006. However I have a version dating from May 29, 2010 (using stix fonts I guess). Could you please leave a copy of the most recent version on the wiki? It would be extremely useful… Best regards: OK

Thanks for looking into this. Kind regards WIlli

enumeration of equations containing \mathcases
by j. van den hoff 10 Feb '15

10 Feb '15

hi list, admittedly I've posted this problem two times 6-8 weeks ago already but since I did not get a single response (not even RTFM...) I try it now a third time (hoping this is not considered spamming the list ...): question: how can I get properly aligned enumeration of equations that use `\mathcases'. example: 8<-------------------------------------------------------------- bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla \placeformula \startformula K_1 \rightarrow \startmathcases \NC f \NC for $f \ll PS$ (flow limited transport) \NR \NC PS \NC for $f \gg PS$ (diffusion limited transport) \NR[+] \stopmathcases \stopformula bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla \stoptext 8<-------------------------------------------------------------- does "subcases enumeration" in the second case but this is not aligned with the right text margin so it can not be used easily to "fake" the enumeration of the whole equation. \placeformula on the other hand does not print an equation number at all (contrary to what it usually does. I'm at a loss how to solve this... thx,joerg

Is it a Metapost or > Metafun macro? It is a MetaFun macro in mp-tool, afaik. The idea of filling a path is sometimes clipping to a path. Here is a way to do your task with (almost) only MetaPost: \startMPpage[offset=2mm] path p, q ; p := unitsquare scaled 4cm ; z1 = point 3.6 of p ; q := z1 -- urcorner p -- lrcorner p -- llcorner p -- cycle; for i = 8 step -.5 until 0: draw (i,0)*cm -- (i-4,4)*cm withpen pencircle scaled 2pt withcolor blue; endfor; clip currentpicture to q; draw p ; draw q ; label.llft("B", llcorner p) ; label.lrt ("C", lrcorner p) ; label.ulft("A", ulcorner p) ; label.urt ("D", urcorner p) ; label.lft ("M", z1) ; \stopMPpage …just in case it helps to clarify.

two features in ViewerPreferences for printing
by Pablo Rodriguez 09 Feb '15

09 Feb '15

Hans, for a small book I’m publishing online (https://archive.org/download/ensayo-escritura/ensayo-escritura.pdf) it would be extremely useful to have two features from the PDF spec implemented. These are PrintScaling and Duplex (page 364 of the PDF spec). They are two entries in the ViewerPreferences. Both features are extremely useful to avoid issues when explaining double-sided printing and not reducing margins (in some cases, this reduction to margins is critical [such as in the sample above]). I think this is not only useful to many users. Could these features be implemented in ConTeXt? Many thanks for your help, Pablo -- http://www.ousia.tk

Disappearing backgrounds/pagenumbers with \page[none]
by Wolfgang Schuster 09 Feb '15

09 Feb '15

Hi, there was a problem on TeX SE [1] where page numbers disappear for a whole chapter when \page[none] is used to hide the numbers on empty left pages in a double sided document. As can be seen in the following example the page numbers and background on the last two pages disappear when “missing” mode is enabled. This happens when the “blank” option for \page is used without a change in the page number (we are already at page 3 when \page[yes,blank,right] is expanded). %%%% begin example \setupbackgrounds[page][background=color,backgroundcolor=gray] %\enablemode[missing] \starttext \dorecurse{6}{\input knuth\par} % End the current page before \page[blank] is called \doifmode{missing}{\page} \page[yes,blank,right] \dorecurse{6}{\input knuth\par} \stoptext %%%% end example [1] http://tex.stackexchange.com/questions/225603/missing-page-numbers-first-ch… <http://tex.stackexchange.com/questions/225603/missing-page-numbers-first-ch…> Wolfgang
