issue with font features
by Pablo Rodriguez 24 Jul '18

24 Jul '18

Dear list, I have the following sample: \definefontfeature[effect]%[effect=.2] [effect={width=.3,delta=0.4,factor=0.3}] \definefontfeature[oldle][onum=yes] \setupbodyfont[palatino] \starttext {\feature[+][effect]1234567890} 1234567890 {\feature[+][oldle]1234567890} \stoptext I wonder why the first font feature ("effect") doesn’t work. What am I missing? Many thanks for your help, Pablo -- http://www.ousia.tk

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.

Align the chapter-title to the middle of the header
by Huseyin Özoguz 23 Jul '18

23 Jul '18

Dear list, how can I align the text of the header in the double-page layout to the middle? I want something like that: \setupheadertexts [{\startalignment[middle] \definedfont[name:Gentium_Basic at 9pt]\getmarking[chapter] \stopalignment}][] [][] Of course, that does not work. By default, there are only the four places to set the text in the header: left and right in the header for both pages. How to place the chapter-title (or whatever) into the middle of the header? Thanks. Huseyin

Problem with pagella font (beta)
by Fabrice Couvreur 23 Jul '18

23 Jul '18

Hello, I only use the standalone version of ConteXt with Emacs. I can not use the pagella font anymore because the text is in bold type. Wolfgang told me a discussion about this problem that still does not seem to be resolved. By cons, no problem with ConteXt of Texlive 2018. Thank you Fabrice

two questions about endnotes
by Robert Zydenbos 23 Jul '18

23 Jul '18

First question: I am considering using endnotes in my book instead of footnotes. There is a command \endnote, but I do not see the notes appear anywhere in my text. What am I doing wrong? What I tried: \starttext Dit is iets met een endnote.\endnote{Wat een zooi. Werkt het?} \page Het zou moeten werken,\endnote{Ja, toch?} want ik zie tekens in de tekst. \stoptext Second question: Is it possible to use endnotes as well as footnotes in the same text? -- Robert

startlines in margin
by Rik Kabel 21 Jul '18

21 Jul '18

List, Can somebody suggest an export-friendly mechanism to put fixed lines into the margin? Use case: I am reproducing a 17th century text with marginal footnotes. I do not need a solution that works with both pdf and xml, but there is less mode fiddling if it does. This example: \setupbackend [export=yes] \starttext \subject{\tex{startlines} in margin} \startparagraph \margintext{\startlines abc def ghi jkl mno pqr \stoplines} \input knuth \stopparagraph \subject{\tex{crlf} in margin} \startparagraph \margintext{abc def\crlf ghi\crlf jkl\crlf mno pqr} \input knuth \stopparagraph \subject{\tex{\textbackslash} in margin} \startparagraph \margintext{abc def\\ ghi\\ jkl\\ mno pqr} \input knuth \stopparagraph \subject{\tex{startlines} in main flow} \startparagraph \startlines abc def ghi jkl mno pqr \stoplines \input knuth \stopparagraph \stoptext generates the following xml with \startlines and \crlf: <margintext detail="margintext" chain="margintext"><lines detail="lines" chain="lines"><line>abc def ghi jkl mno pqr</line></lines></margintext> and no <lines> element at all with \\, while it generates proper lines in the main flow: <lines detail="lines" chain="lines"><line>abc def</line><line>ghi</line><line>jkl</line><line>mno pqr</line></lines> I also note that \startlines in \margintext does not work in pdf output, but both \crlf and \\ do, and \bpar..\epar works in margintext for pdf output but breaks strangely in xml (the \epar ends the margintext element and the rest is set as body flow paragraphs). -- Rik
