Set up a theorem style
by Fabrice Couvreur 26 Jul '18

26 Jul '18

Hello, I used LaTeX for a long time before converting (with difficulty !) to ConteXt. For example, to define my new theorems, I used the amsthm package and I did this : \newtheoremstyle{theoremdd}% name of the style to be used {\topsep}% measure of space to leave above the theorem. E.g.: 3pt {\topsep}% measure of space to leave below the theorem. E.g.: 3pt {\itshape}% name of font to use in the body of the theorem {0pt}% measure of space to indent {\bfseries}% name of head font * {. ---}% punctuation between head and body* { }% space after theorem head; " " = normal interword space {\thmname{#1}\thmnumber{ #2}\thmnote{ (#3)}} \theoremstyle{theoremdd} \newtheorem{thmd}{Theorem}[section] I'm trying to do the same thing with ConTeXt but I can not do it completely : \setupenumerations[ before={\blank}, after={\blank}, text=Théorème, alternative=serried, title=no, prefix=yes, prefixsegments=chapter, way=bysection, right=., titlestyle=bold, style=italic, width=broad, ] \defineenumeration[theorem] \starttext \startchapter[title={First Chapter}] \startsection[title={First Section}] \dorecurse{2}{ \starttheorem \input ward \stoptheorem} \stopsection \stopchapter \startchapter[title={Second Chapter}] \startsection[title={Second Section}] \dorecurse{2}{ \starttheorem \input ward \stoptheorem} \stopsection \stopchapter \stoptext Thanks Fabrice

Issues with vertical spacing in simple case
by Joseph Canedo 26 Jul '18

26 Jul '18

Dear list, Trying to build a MWE for a problem with unexpected page break (near a \blank[line, samepage]) I could not yet reproduce yet, I came up with strange output. With latest beta mtx-context | current version: 2018.07.17 17:25 MWE : \starttext \dorecurse{5}{ \input knuth \blank[line, samepage]Second. \input zapf \blank[line, samepage]Second maybe vertically wrong align? } \stoptext Please see in page 2, the line printing : Second maybe vertically wrong align? (topskip related?) Seems very close to next line for an unknown reason to me. Thanks Best regards Joseph

Limit text width in items
by Henning Hraban Ramm 26 Jul '18

26 Jul '18

Hello again, in the MWE below I’d like to limit the run width of the item text so that the (page) number is standing out, e.g. • This is a long and winding text that leads to a number .......... 99 The text can become one or several lines long. I tried to put the text in boxes, e.g. \simplealignedbox{}{}{\vbox{...}} but I got only ugly spacing. Also, the last line of the text continues in that leaders and number. --- \def\leaderfill{\leaders\hbox to 1em{\hss. \hss}\hfill} \starttext \startitemize[packed,joinedup] \startitem \input tufte \leaderfill 33 \stopitem \startitem \input knuth \leaderfill 99 \stopitem \stopitemize \stoptext --- Greetlings, Hraban --- https://www.fiee.net http://wiki.contextgarden.net https://www.dreiviertelhaus.de GPG Key ID 1C9B22FD

referencing the customized enumeration with framed title
by Jeong Dal 26 Jul '18

26 Jul '18

Hi, Some time ago, I am able to use following code(the framed title for Theorems and etc.) Thank Wolfgang and Otared again. Since it uses the customized style of numbering, there is a problem to reference them. As in the following code, \in{Definition}[] shows no number and \in{Theorem}[] shows ?? instead of numbers while \in{Exam}[] shows correctly. Is there a way to show the numbers correctly? Thank you for reading.

about the defining itemized columns.
by Jeong Dal 26 Jul '18

26 Jul '18

Dear all, In mathematics, there are many occasions to make exercise problems in columns, and I did that using “tabulate” as following. Thanks Hans for this method! %%%%%%% \define\iTwo{\starttabulate[||w(.42\makeupwidth)||lw(.42\makeupwidth)|]} \define\iThree{\starttabulate[||lw(.28\makeupwidth)||lw(.28\makeupwidth)||lw(.28\makeupwidth)|]} \define\iFour{\starttabulate[||lw(.21\makeupwidth)||lw(.21\makeupwidth)||lw(.21\makeupwidth)||lw(.21\makeupwidth)|]} \starttext \startitemize[n] \iTwo \NC \itemtag \NC test1 \NC \itemtag \NC test2 \NC\NR \NC \itemtag \NC test3 \NC \itemtag \NC test4 \NC\NR \NC \itemtag \NC test5 \NC \itemtag \NC test6 \NC\NR \stoptabulate \stopitemize \stoptext %%%%%%% It works well. Since the numbers in the definitions are calculated by .84/2, .84/3, .84/4, I want to combine those definitions in one form. Is it possible to define a one definition which can be set by argument as following. \define[1]\iCol{\starttabulate[|*{#1}{|lw(.84/#1)\makeupwidth|}]} When I call it \iCol{2}, the first *{#1} is working, but the second #1 is a problem. I tried \ctxlua for division, but it didn’t work either. Is there a nice way to define them in one definition? It may be my greedy hope. Thanks for reading. Best regards, Dalyoung

Questions to PDF/A compliant documents: missing ICC files?
by Tomas Hala 26 Jul '18

26 Jul '18

Hi all, at http://wiki.contextgarden.net/PDF/A I found the following: """"" In ConTeXt mkiv, in order to create such a compliant PDF/A file, one can do as follows: first install (or check that they are present) the following color profiles files default_cmyk.icc default_gray.icc default_rgb.icc ISOcoated_v2_300_eci.icc into tex/texmf-context/colors/icc/profiles of your Context standalone directory. The default_*.icc files are part of ghostscript... """"" So I checked that they are present (CentOS 6.6, GPL Ghostscript 8.70) and I discovered that these files are not present at any ConTeXt (or TeX) installation from TeXlive neither as separate files, nor at file context/colors/icc/context/colorprofiles.xml. Only default_gray.icc is present as a part of ConTeXt installations from our garden. Therefore, I would like to ask (a) where I can find the set of original default*.icc files, (b) what is the reason why these files are not included in the TeXlive and garden installations, (c) if it is possible to add it there for future, and (d) if the produced PDF (with \setupbackend[format={pdf/a-1b:2005}...]) is PDF/a compliant when these icc files are not present and the whole content of the document is only in black (i.e. no grayscale, no colours). Our university decided to be "PDF/a compliant", that is the reason why I am asking. Best wishes, Tomáš

Modifying bibliography entries using lua
by Stanislav Sokolenko 24 Jul '18

24 Jul '18

Dear list, I'm struggling to output bibliography entries into lua for string modification (like making a particular author name bold). In effect, I just need something like the following: \starttexdefinition btx:customauthor \startluacode local text = context.btxflush('author') -- tex.sprint(text) -- fails because text remains nil \stopluacode \stoptexdefinition It's clear that btxflux is the wrong function for this as it writes the contents to file rather than returning a variable in lua... Is there a way to directly access what btxflush is writing through the publications table or other means? I've gone over the source code but I can't decipher what btxflush is actually doing. Thanks, Stan Longer MNWE: \stopluacode \startbuffer[ref] @article{solo, author = {Lastname, Firstname}, title = {Solo work}, journal = {Journal}, year = {2000}, month = {1}, volume = {1} } \stopbuffer \usebtxdataset[ref][ref.buffer] \setupbtx[dataset=ref] \definebtxrendering[ref][dataset=ref] \setupbtx[default:cite] [alternative=authoryear, etallimit=1] \starttexdefinition btx:customauthor \startluacode local text = context.btxflush('author') -- tex.sprint(text) -- text remains nill \stopluacode \stoptexdefinition \startsetups btx:default:list:article \texdefinition{btx:customauthor} \texdefinition{btx:default:title} \texdefinition{btx:default:journal} \texdefinition{btx:default:year} \removeunwantedspaces \removepunctuation \btxperiod \stopsetups \starttext Citations: \cite[solo] \startsubject[title=Bibliography] \placelistofpublications[ref][method=dataset] \stopsection \stoptext

Hi, I want to use the some symbols for phone and email (envelope) in my curriculum vitae to get it look more modern. How is the way to do it in ConTexT? Thanks -- Dr. Lizardo M.
