I don’t understand the question. A ConTeXt layer is not a PDF layer. All the objects are manipulatable in Acrobat Pro (or another PDF editor), there’s no grouping on the PDF level. > 2.

Of course calculations are easier in Lua, but in my image placement macros I struggled a lot with numbers vs. measures/dimensions, regardless if in Lua or on the TeX level.

Issue with page break at \blank samepage
by Joseph Canedo 27 Jul '18

27 Jul '18

Dear list, Somehow the Following MWE processed with recent betas : %%%% \setuplayout[grid=both] % commenting does not change the result \starttext \dorecurse{31}{ A. } \input knuth \blank[line, samepage]Second. \stoptext %%%% Outputs a pdf with 2 pages and « Second » is left alone in 2nd page. This is different from online context with prints last line of knuth par in 2nd page too. I thought that « samepage » specifier in \blank prevented page break at that point ? Is there another option for this now ? Thanks Best regards Joseph

URLs break bib export
by Rik Kabel 27 Jul '18

27 Jul '18

The new tagged biblography export is very nice, but there is a routine (marked UGLY in the source) that causes processing to fail with otherwise-valid input. The failure message is ...eXt/tex/texmf-context/tex/context/base/mkiv/back-exp.lua:3889: invalid capture index stack traceback: [C]: in function 'gsub' ...eXt/tex/texmf-context/tex/context/base/mkiv/back-exp.lua:3889: in function <...eXt/tex/texmf-context/tex/context/base/mkiv/back-exp.lua:3747> (...tail calls...) and two URLs which cause this problem are: url = {http://www.jerwood-no.org.uk/pdf/Dunning%20Kruger.pdf}, url = {http://oll.libertyfund.org/?option=com_staticxt&staticfile=show.php\%3Fcollection=46&Itemid=27}, These URLs caused no problem with PDF output or in the previous exports, although they were not printed and exist only in the bibliography. Do I need to protect the special characters in the bib file, or is this a problem with the UGLY code? -- Rik

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

Numbering properties in a chapter
