new interface to simplefonts
by Pablo Rodriguez 23 Jan '14

23 Jan '14

Dear list, using the latest beta from today (ConTeXt - 2014.01.22 01:31) in Linux 32-bit, I cannot get the new simplefonts working. Here is the sample: \definefallbackfamily [mainface] [serif] [DejaVu Serif] [range={greek,extendedgreek},force=yes] \definefontfamily [mainface] [serif] [TeX Gyre Pagella] \setupbodyfont[mainface] \starttext \input knuth χαλεπὰ τὰ καλά \stoptext But I only get the font LatinModernMath-Regular. Am I missing something or is this a bug? Many thanks for your help, Pablo -- http://www.ousia.tk

enable kerning with discretionary hyphen
by Pablo Rodriguez 23 Jan '14

23 Jan '14

Dear list, as I have asked in a previous message to the list, I wanted to be able to hyphenate \ConTeXt. Aditya kindly suggested the use of \discretionary, but this has an unintended collateral effect: kerning is disabled in the word. I can specify kerning with \discretionary, such as in: \def\ConTeXt{Con\discretionary{-}{}{\kern-.06em}\TeX{}t} But this also has another consequence: this works right for Pagella regular, but this is wrong with the italic font or in small caps (also with the bold or bold italic fonts, but I don’t use them). \hyphenation would be the way to solve this, but I don’t know how to make it work: \def\ConTeXt{Con\TeX{}t} \hyphenation{Con-\TeX} \starttext \hsize\zeropoint \ConTeXt ConTeXt \stoptext Even in the case it could work, I would like to know how I could define commands (\ConTeXt or \TeX) only referred to individual fonts. Many thanks for your help, Pablo -- http://www.ousia.tk

Comment after \startseparatedlist[...]
by Joshua Krämer 22 Jan '14

22 Jan '14

Dear list, if there is a comment after \startseparatedlist[...] from the database module, context fails. Thus, this example in the wiki doesn't work: http://wiki.contextgarden.net/M-database Minimal example: \usemodule[database] \defineseparatedlist[Test] [ before=\bTABLE, after=\eTABLE, left=\bTD, right=\eTD, first=\bTR, last=\eTR ] \starttext \startTest % problematic comment Eins, zwei, drei \stopTest \stoptext Kind regards, Joshua Krämer

Reference in a startcombination environment
by MANUEL GONZALEZ SUAREZ 21 Jan '14

21 Jan '14

Dear friends I would like to know if I can make a reference (via \in, \at, etc.) in a \startcombination ... \stopcombination environment to each subfigure. For example, I have a Figure 1.1. (Sky) contains (a) the moon (b) the stars. How could get it to appear in the text "see Figure 1.1. (b)? Thanks very much. Manuel

MkIV XML and |c|c|c|
by Kate F 21 Jan '14

21 Jan '14

Hi, I'm trying to glue MkIV XML handling to ConTeXt's tabulation. My markup has a HTML-style table model, with an arbitary number of <col> elements. My problem is to produce the |c|c|c|c| format based on the number of <col> elements I have, rather than hardcoding a specific number of columns. I thought I could do something like this, but unfortunately the string produced by \xmlconcat{#1}{col}{\|} seems to be ignored: % in practice this would produce various alignments, not just "c" \startxmlsetups xml:col c \stopxmlsetups \startxmlsetups xml:table \starttabulate[\|\xmlconcat{#1}{col}{\|}\|] \xmlall{#1}{thead|tbody} \stoptabulate \stopxmlsetups Whereas this works fine, as I'd expect: \starttabulate[|c|c|c|c|] (I'm also confused about the escaping for \| there. I guess the [] is a special environment, with | being given a different catcode, perhaps?) Is there a way to do this, with the number of columns and their alignment generated from the input XML? Thanks, -- Kate

New header
by Fabrice Couvreur 21 Jan '14

21 Jan '14

Hi, I use the following header to my statements made with tittlesec package. \makeatletter \newcommand{\@classe}[1]{} \newcommand{\classe}[1]{\gdef\@classe{#1}} \newcommand{\@typedevoir}[1]{} \newcommand{\typedevoir}[1]{\gdef\@typedevoir{#1}} \newcommand{\@numerodevoir}[1]{} \newcommand{\numerodevoir}[1]{\gdef\@numerodevoir{#1}} \AtBeginDocument{\section{\@typedevoir\space\no\@numerodevoir}} \titleformat{\section}[frame] {\normalfont} {\footnotesize\enspace\itshape\@classe\enspace--\enspace Le \@date\enspace} {10pt} {\Large\scshape\bfseries\filcenter} \makeatother I want to gradually move to ConTeXt and I tried to create the same header. But I do not yet know all the commands to do with ConTeXt. \setuptextrules [style=\it,location=top] \define[6]\MyHeader{% \textrule[top]{#1\space--\space\date[d=#2,m=#3,y=#4]}{\startlinealignment[middle]{\cap \bf #5 \space n\high{{o}}\space {#6}}\stoplinealignment\blank\textrule}} \starttext \MyHeader{Seconde GTA}{11}{1}{2014}{Devoir de Mathématiques}{7} \stoptext Thank you.

error bar gap with pgfplots/tikz and custom colour
by Joshua Krämer 20 Jan '14

20 Jan '14

Dear list, I'm using pgfplots to create some bar charts with error bars, and I want to use custom colours for them. This works, but if I mix a custom colour with another colour, it results in a gap between the error bar line and the error bar mark. If two custom colours are mixed, the gap seems to be doubled. Mixing with predefined colours works normally. MWE: \usemodule[tikz] \usemodule[pgfplots] \definecolor [Blue] [h=3465a4] \definecolor [White] [h=ffffff] \pgfplotsset{compat=newest} \starttext \starttikzpicture \startaxis[ybar, error bars/y dir=both, error bars/y explicit] \addplot+[blue!50!white] coordinates {(1,5) +- (0,3)}; \addplot+[Blue] coordinates {(1,5) +- (0,3)}; \addplot+[Blue!50!white] coordinates {(1,5) +- (0,3)}; \addplot+[Blue!50!White] coordinates {(1,5) +- (0,3)}; \stopaxis \stoptikzpicture \stoptext Kind regards, Joshua Krämer

reference to structureuservariable
by Peter Münster 20 Jan '14

20 Jan '14

Hi, How can I read a structureuservariable at the end of the section, when there are subsections? Example: --8<---------------cut here---------------start------------->8--- \starttext \startsection[title=sec][foo=bar] % \edef\myFoo{\structureuservariable{foo}} % workaround \startsubsection[title=sub 1] sub 1 \stopsubsection \startsubsection[title=sub 2] sub 2 \stopsubsection \par foo is \structureuservariable{foo}. % foo is \myFoo. % workaround \stopsection \startsection[title=sec][foo=bar] no subsections...\par foo is \structureuservariable{foo}. \stopsection \stoptext --8<---------------cut here---------------end--------------->8--- Is there a clean way or do I need to use something like the above workaround? TIA for any hints, -- Peter
