(again) issue with lpath and conditional
by Pablo Rodriguez 21 Mar '18

21 Mar '18

Dear list, I have the following sample: \startbuffer[demo] <doc> <pre class="tex typeset fullwidth"> <code> a </code> </pre> <pre class="tex typeset"> <code> b </code> </pre> </doc> \stopbuffer \startxmlsetups xml:initialize \xmlsetsetup{#1}{doc}{xml:*} \xmlsetsetup{\xmldocument} {pre[contains(@class,'typeset')]/code} {xml:pre:code} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:doc \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:pre:code \xmlinfo{#1} \xmlpath{#1} \xmldoifelse{#1}{../pre[contains(@class,'fullwidth')]} %~ \xmldoifelse{#1}{{pre[class*="fullwidth"]}} {\startpar Full–width.\stoppar} {\startpar Another width.\stoppar} \stopxmlsetups \starttext \xmlprocessbuffer{main}{demo}{} \stoptext It is beyond my kmowledge why the lpath "{../pre[contains(@class,'fullwidth')]}" doesn’t return true, when \xmlinfo shows "[code]" and \xmlpath is "doc/pre/code" (indices aren’t relevant here). Neither does the css selector work. What am I missing in the lpath and the css selector? Many thanks for your help, Pablo -- http://www.ousia.tk

Support for musl
by Henri Menke 21 Mar '18

21 Mar '18

Dear list, I'd like to support Linux platforms which use musl (https://www.musl-libc.org/) instead of glibc, like for instance Alpine Linux. How would I go about this? Can you share existing build scripts for, e.g. Linux-64? Do I have to provide build infrastructure? Cheers, Henri

Questions about creation of PDF's
by Tomas Hala 20 Mar '18

20 Mar '18

Hi all, I came across the following changes in behaviour of compilation. Using this minimal example \starttext \pdfminorversion=3 Hello! \stoptext I found out that since TL2010 till TL2015, the output PDF is of the version 1.3 whereas TL2016 (which I do not use), TL2017 and current ConTeXt from the garden produce PDF of version 1.7. Is there any other (or new) way how to set the output version directly on the source file? Simultaneously, I found out that the produced PDF by older version -- since TL2010 till TL2015 -- contains, e.g., "Creator: ConTeXt - 2015.05.18 12:26" whereas TL2017 and current ConTeXt contains very short information "Creator: LuaTeX + ConTeXt MkIV" Is possible to extend this information adding the date&time of the ConTeXt, similarly to the older ones? Many thanks in advance, Tomáš

Adding a parameter to a module
by John Grasty 20 Mar '18

20 Mar '18

Hello list, One more question. Since I could not figure the problem with the wiki article for a title, I have turned my attention to modify the t-title module for my needs. If I want to add let's say a publication location, how would I go about that? I have copied and renamed t-title.mkvi to p-mymodule.mkvi. I have changed the formatting to suit my needs, but I can't not figure out how to add parameters. What is the connection to the t-title.xml interface file? I don't need it done for me, but I do need just a bit of help getting going in the right direction. :-D Thanks so much for the help and the great software! John Grasty

\completeindex and \setuparranging
by Gerard 20 Mar '18

20 Mar '18

Bonjour, Hi ! Pablo, ok for the remark ! I leave the previous subject and I open mine because it's not solved > Le 18/03/2018 à 23:21, Gerard a écrit >> >> Thank you Wolfgang for the solution : >> >> context --arrange my_document.tex >> I responded too quickly. Look at the two pictures attached : - \placeindex does not mark the pages - \completeindex only marks page 19 (the last page) That's the context : ----------------------- \setuppapersize[A5][A4,landscape] \setuparranging[2UP] \setupregister[index][n=2, pagestyle=bold] \starttext .... \externalfigure[Alaude][width=\textwidth]\index{Alaude} \blank \externalfigure[Andro][width=\textwidth]\index{Andro} .... \page \completeindex \stoptext --------------------------------- and running by "context --arrange my_document.tex" It's ok with : ------------------------- \setuppapersize[A5]%[A4,landscape] %\setuparranging[2UP] ------------------------- Thanks for the help. Gérard... and thanks to "google translate" :) > Le 18/03/2018 à 20:32, Wolfgang Schuster a écrit : >> >>> survoje <mailto:survoje@free.fr> >>> 18.

issue with \xmlattribute{#1}{.}{id}
by Pablo Rodriguez 19 Mar '18

19 Mar '18

Dear list, in an environment to parse an XML document, I use \reference[\xmlattribute{#1}{.}{id}]. Since it doesn’t do what I need, I checked the pure command "\xmlattribute{#1}{.}{id}". >From id="spieker-weiss" and id="computer-mind", I get "spieker-weissmain::4103" and "computers-mindmain::4384". What am I missing there or how could I get pure identifiers with no "main::9999" suffix? Many thanks for your help, Pablo -- http://www.ousia.tk

Title example from the Wiki is broken
by John Grasty 19 Mar '18

19 Mar '18

Hello, I trying to use the "In ConTeXt: A more advanced solution" example from the wiki [http://wiki.contextgarden.net/Document_Titles] to learn how modules and the like work in ConTeXt. I saved the module as p-titlepage.mkvi, because I could not get my module to load instead of the included third party one. So my questions are: 1. Is there a way to load my module with the name title ahead of the supplied one? I saved it to <texroot>/texmf-project/tex/context/shared and <texroot>/texmf-local 2. Any idea what the error is in the wiki (or my use of it)? Thanks, John Here was the error: tex error > tex error on line 46 in file /Users/jgrasty/context/tex/texmf-local/p-titlepage.mkvi: !

current
by Hans Hagen 18 Mar '18

18 Mar '18

Hi, As the tex live code freezing is near we made a "current" (luigi does the checking in tex live). As far as we can see it works ok with luatex 1.07 (the context garden will have 1.08 in a while but that will influence only some low level context, more convenenience stuff).
