Math literal colon
by Hans Aberg 24 Jul '15

24 Jul '15

The LaTeX package unicode-math has an option colon=literal, which makes it behave as in math functions (as in example below). Has ConTeXt a similar option? ---- lualatex ---- \documentclass[leqno]{article} \usepackage[colon=literal]{unicode-math} \begin{document} The function $f: A → B$. \end{document} --------

chapter only in bookmarks (not in text or in TOC)
by Pablo Rodriguez 24 Jul '15

24 Jul '15

Dear list, I have the following sample: \showframe \setupinteraction[state=start] \placebookmarks[chapter] \definehead[hiddentitle][chapter] \setuphead[hiddentitle][incrementnumber=no] \starttext \completecontent \hiddentitle{Prologue} aa\page aa \chapter{Foreword} aa \chapter{Introduction} \stoptext I would like to have a \hiddentitle command that doesn’t display the heading in text (and adds no extra space), that it doesn’t add it to the table of contents, but that it adds it as a bookmark. How should I define \hiddentitle to get that? Many thanks for your help, Pablo -- http://www.ousia.tk

issue with font and lua code
by Pablo Rodriguez 24 Jul '15

24 Jul '15

Hans, I have the following sample (it includes Lua code for underscore hyphenation): \startluacode function document.addfunnyhyphen(tfmdata) local underscore = utf.byte("_") local char = tfmdata.characters[underscore] if not char then return end tfmdata.characters[0xFE000] = { width = 0, height = 0, depth = 0, commands = { { "right", -char.width }, { "down", char.depth }, { "slot", 1, underscore }, } } end utilities.sequencers.appendaction("aftercopyingcharacters", "after","document.addfunnyhyphen") \stopluacode \definehyphenationfeatures [underscore] [righthyphenchar="FE000] \setuphyphenation [method=traditional] \sethyphenationfeatures [strict] \definefontfamily[svb][rm][SV Basic Manual] \setupbodyfont[svb] \starttext \hyphenatedword{legibility} \stoptext For some reason, the font gives the following error with the Lua code (font can be downloaded from http://dl.dafont.com/dl/?f=sv_basic_manual) lua error > lua error on line 33 in file svb.tex: .../ctxbeta/tex/texmf-context/tex/context/base/font-ctx.lua:1194: bad argument #9 to 'define' (number expected, got nil) stack traceback: [C]: in function 'define' .../ctxbeta/tex/texmf-context/tex/context/base/font-ctx.lua:1194: in function <.../ctxbeta/tex/texmf-context/tex/context/base/font-ctx.lua:1049> 33 >> \setupbodyfont[svb] The weird thing here is that the Lua code isn’t applied to the problematic font. Is there a way to fix this strange interaction? Many thanks for your help, Pablo -- http://www.ousia.tk

Line wrapping inconsistency with tolerance, alignment and framed
by Christoph Reller 24 Jul '15

24 Jul '15

Hi, I have an (admittedly carefully crafted) example, see below. My question: Why is the line wrapping different for this case within a framed and outside of a framed? How can I control the amount of space left on a line before breaking the line within and without a framed consistently? Any insight is welcome. Christoph MWE: \setuptolerance[horizontal,stretch,verytolerant] \defineframed[myframe][align=flushleft,frame=off,offset=0pt] \starttext \def\super{supercalifragilisticexpialidoc} \startalignment[flushleft] \unhyphenated{\super\ + \super\ + \super\ + \super} \stopalignment \myframe{\unhyphenated{\super\ + \super\ + \super\ + \super}} \stoptext

bug in blank pagebreak?
by Pablo Rodriguez 24 Jul '15

24 Jul '15

Dear list, I have the following sample: \definepagebreak [right:pagebreak] [yes, blank, right] %~ [yes, header, footer, right] \setuppagenumbering [location=inmargin] \setupheadertexts [Header text] \setuphead [chapter] [page=right:pagebreak, header=empty] \starttext \chapter{First Chapter} \dorecurse{12}{\input zapf\par} \stoptext With beta from 2015.07.16 13:30, footer from page 1 and header from page 2 are gone. But if I redefine the pagebreak with "header, footer" instead of "blank", both missing header and footer are placed in their right places. Isn’t it a bug? Or am I missing something? Many thanks for your help, Pablo -- http://www.ousia.tk

Multiline equations break grid in columnsets
by Sebastian Ørsted 24 Jul '15

24 Jul '15

I reported this some days ago, but it was a rather short report, which might explain why nobody has reacted upon it yet. So this time I'll go into greater detail: The grid system in columnsets works very well until the moment you include a multiline equation somewhere. This causes the entire rest of the page to be out of alignment with the grid. Try running this code with MkIV: \setuplayout [grid=yes] \setupindenting[yes,medium] \definecolumnset[example][n=2] \setupformulas[indentnext=auto] \starttext \showgrid \startcolumnset[example] \input knuth \input knuth \input knuth \startformula \startmathalignment \NC x^2 + y^2 \NC = z^2\NR[+] \NC u^2 + v^2 \NC = w^2\NR[+] \stopmathalignment \stopformula \input knuth \input knuth \input knuth \stopcolumnset \stoptext A picture of the result can be found in this question on TeX.SE <http://tex.stackexchange.com/questions/254815/grid-on-aligned-equations-in-…> .

reverse page order and reverse page numbering in one part of a book
by talazem＠fastmail.fm 24 Jul '15

24 Jul '15

Dear all, I am producing a book that is divided into two sections. The book is published in English, and thus it runs left to right. Part one is an academic study in English. Part two is a critical edition of an Arabic text. The book is exactly 100 pages long, with fifty pages going to the English study, and fifty pages to the Arabic edition. In Part One (which includes all the front matter of the book, such as the table of contents, etc.): the page ordering runs left-to-right, the pagination runs from 1 to 50, and the page numbers should be printed in Arabic numerals. However, in Part Two (the Arabic text): the page ordering should run right-to-left, the page numbers should run in “reverse” pagination (in which “page 1" of the critical edition begins at the “back” of the book), and the page numbers should be printed in Hindi numerals. In other words, the structure of the book’s pages would be as follows (ellipses used to jump): 1 2 3 … 48 49 50 ٥٠ ٤٩ ٤٨ … ٣ ٢ ١ I would like the Table of Contents then to look something like this: Forward . . . . . . v English Study . . . 1 Arabic Edition. . . ١ Index of names. . . ٥٠ So my question is: is this currently possible in ConTeXt, to produce a single PDF, with such a TOC, from one file? Or am I bringing on too much of a headache upon myself, and it is easier to produce two separate files — but if so, how would one produce a TOC that includes the parts and page numbers of both documents? Many thanks, and best wishes, Talal

I have found this wiki: http://wiki.contextgarden.net/Commands_with_KeyVal_arguments But since I do not know Lua, I would appreciate that someone gets me started with my example.

Illegal parameter number in definition
by juh 23 Jul '15

23 Jul '15

Hi all, I am totally new to ConTeXt. I am a long time LaTeX user and I got interested in ConTeXt by a posting from Pablo in the Pandoc mailing list. So he is to blame if you have to read silly questions from me in the future. ;-) To learn a bit more about ConTeXt I try to make an environment to typeset TEI-XML files from http://www.deutschestextarchiv.de (DTA) I ran into a problem with this XML from DTA: <head> <hi rendition="#g">Zehenter Brief.</hi> </head><lb/> <p><hi rendition="#in">S</hi>ie sind also mit mir darinn einig, und durch den Innhalt meiner I tried to map the rendition attribute to ConTeXt with this code: \startxmlsetups xml:teisetups \xmlsetsetup{#1}{*}{-} \xmlsetsetup{#1}{TEI|text|body|div|head|p|lb}{xml:*} \xmlsetsetup{#1}{hi[@rendition='#g']}{xml:hi} \stopxmlsetups The attribute of '#g' makes trouble. I get the following error message. tex error > error on line 5 in file tei-style.tex: ! Illegal parameter number in definition of \14>:xml:teisetups <to be read again> g <argument> ...lb}{xml:*}\xmlsetsetup {##1}{hi[@rendition='##g ']}{xml:hig} \syst_setups_start_xml_indeed ...1\expandafter {#3 } l.5 \stopxmlsetups 1 \startxmlsetups xml:teisetups 2 \xmlsetsetup{#1}{*}{-} 3 \xmlsetsetup{#1}{TEI|text|body|div|head|p|hi|lb}{xml:*} 4 \xmlsetsetup{#1}{hi[@rendition='#g']}{xml:hig} 5 >> \stopxmlsetups I think that I kind of understand the message. The hash '#' isn't allowed in this place. Is it possible to escape the hash somehow or to solve this issue in an other way?
