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)

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 22 Jul '18

22 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

Question to covers
by Tomas Hala 21 Jul '18

21 Jul '18

Hi all, I would like to ask whether we have got some module or macros for comfortable proposing of covers for different kinds of binding, containing automatic computation of the corresponding measurments and displaying the parts for bookbinders (eg cutting lines, protection zones, bends, pasting parts etc.) The best, Tomáš

Crossref in bibtex
by context＠joshuamoerman.nl 20 Jul '18

20 Jul '18

Hi all, I am now playing around with ConTeXt to see if it fits my needs for writing my thesis :-). One thing which did not work for me was the use of crossref in bibtex entries. This feature is used when generating bibtex entries via DBLP (which is quite standard in computer science). It is used to have one single entry for the journal/conference which the lists the editors. Consequently you can have several paper entries referring to that, without duplicating the editors. This has worked fine for me in LaTeX. But in ConTeXt it seems the crossref is not used at all. Example: \usebtxdefinitions[apa] \usebtxdataset[biblio.bib] \starttext See \cite{PAPER}. Version: \contextversion. \placelistofpublications \stoptext @inproceedings{PAPER, author = {First Last}, title = {PaperTitle}, booktitle = {Conference of BlaBla}, year = {2017}, crossref = {CONF}, } @proceedings{CONF, title = {Conference on BlaBla}, year = {2017}, editor = {Edith Tor}, publisher = {Springer}, } Result (copied from pdf): See (Last, 2017). Version: 2018.07.02 14:39. Last, F. (2017). PaperTitle. In PaperTitle. Conference of BlaBla. Author. Expected (made by manually copying editor/publisher): See (Last, 2017). Version: 2018.07.02 14:39. Last, F. (2017). PaperTitle. In E. Tor (Ed.) Conference of BlaBla. Springer. Should I setup the style differently? Or is the crossref feature not supported? Thanks in advance, All the best, Joshua
