Numbers in appendix roman, but want arabic
by Mikael P. Sundqvist 14 Feb '15

14 Feb '15

Hi, with the example below, I have two problems (that are probably related). In the appendix, the Theorem is numbered "Theorem II" instead of "Theorem 2", i.e. roman numbers are used instead of arabic ones. Also, when I refer to Theorem 1 from the appendix , it says "Theorem I". Again with roman number instead of arabic. I would prefer "Theorem 1". So, the question reads: How can I get arabic numbers also in the appendix? (The appendix itself has the letter A as I want it to) /Mikael \starttext \defineenumeration[Theorem] \defineconversionset [bodypart:sectioncounter] [n,n,n] [n] \defineconversionset [appendix:sectioncounter] [n,n,A] [n] \setuphead[chapter,section][sectionconversionset=sectioncounter] \chapter{Foo} \startTheorem[thm:main] This is a theorem. \stopTheorem \startappendices \title{Appendix} \section{This is the first appendix} \startTheorem This is another theorem. \stopTheorem What if we refer to the first theorem, Theorem~\in[thm:main]? \stopappendices \stoptext

Asciidoc to PDF over Context
by Tobias Famulla 13 Feb '15

13 Feb '15

Hello Mailing-List, I used Latex for a few years in university to create reports for assignments and also to write my bachelor thesis (I would have liked to use Context, but the right schema for citation was not available and I had no time to create it myself). Over the time I got a little bit frustrated with Latex, because it has many modules and most of the time gets the job done, but writing Latex can sometimes be quite hard sometime to me (you have to have the modules installed, tweak around with charactersets, imagepositioning, ...). In between I looked at much smaller and sleaker document representations languages (asciidoc, restructuredText, Markdown) and writing in it is a pleasure compared to Latex (I haven't really tried out Context but looked over the documentation and it looked more promising but shares the same design ideas). Asciidoc is even able to declarate source code listings and formulas. Never the less, the output to Pdf is not always the nicest one. The reason why I now write to this list, is, that I imagine, that Context could be the right processor to create beautiful PDFs out of intermediate formats (DocBook 5 or Asciidoc). For the conversion to Latex a module for asciidoctor (ruby implementation) is in developement. The ideal system I imagine would be close to what is used with HTML and CSS on the web: Having a easy to use file format to writing you documents (Asciidoc or DocBook as intermediate format) and a system to create the PDFs (maybe Context and a Context-Template) So my main questions are: - Are there straigt forward ways to create PDFs with Context using Docbook 5? - Are there "not that hard" possibilites to write extentions to Context to do exactly that (maybe using Lua)? - Does it make more sense, when using another input format like Asciidoc, to write a converter which directly creates a Context-document? (although it might be more versatile to use DocBook for other formats like Markdown or DocBook itself) Sincerely, Tobias

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

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

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
