local picture not found anymore
by H. van der Meer 05 Feb '13

05 Feb '13

Having a file picture.jpg worked fine. Now it results in inclusion of "The picture package by Heiko Oberdiek". Suddenly file searching doesn't start with the current directory anymore but somewhere in the /tex-chain. Were the significant changes here? Something to do with Luatex? I didn't follow the developments for the last few months, so I may have missed an important change. Hans van der Meer

deferred variable lookup in environment?
by Ingo Hohmann 05 Feb '13

05 Feb '13

Hi, sorry if the subject is misleading, I'm not sure how to say it in few words. I'm trying to have the date in a layer in an environment. In the text using the environment, I want to be able to set the date. If the date is not set, the current date should be used, otherwise the set date. This is what I've tried, but it is always the currentdate, that is displayes. Environment file: \def\mydate{} \definelayer[firstpage] % name of the layer [x=0mm, y=0mm, % from upper left corner of paper width=\paperwidth, height=\paperheight] % let the layer cover the full paper \setlayer[firstpage] % name of the layer [hoffset=14cm, voffset=3.5cm] % placement (from upper left corner of the layer) {\framed[frame=on, width=4cm, height=2cm]{ % always shows \currentdate \doiftextelse{\mydate}{\mydate}{\currentdate} }} \setupbackgrounds[page][background={firstpage}] File using this environment: \environment[testenv] \def\mydate{2011-11-11} \starttext % this shows the value from mydate \doiftextelse{\mydate}{\mydate}{\currentdate} \stoptext Is it possible to get \mydate in the layer? Kind regards, Ingo

Alternative width of figures in different documents (problem with modes?)
by Jaroslav Hajtmar 05 Feb '13

05 Feb '13

Hello ConTeXist. I would like use modes alternative to change of image dimensions in different documents (presentation or print version). Compilation in ConTeXt TeXLive 2012 version will compile without error, but without visual effect. Compilation with the standalone version fails. What is problem or eventually. how to solve my problem another way. Thanks Jaroslav Hajtmar Here is my minimal example: \enablemode[presentation] \def\alternativewidth#1#2{ \doifmodeelse{presentation} {width=#1} {width=#2} } \useexternalfigure[COW][cow.pdf][height=5cm, \alternativewidth{3cm}{5cm}] \starttext \input tufte \placefigure[here,force][cowref]{Caption}{\externalfigure[COW]} \input tufte \stoptext

Inclusion of title module in ConTeXt
by Marco Patzer 04 Feb '13

04 Feb '13

Hi Wolfgang et al. what do you think about uploading your title module to the modules repository? Or maybe it can even make it's way into the core. It's just a few lines, nonetheless it's very versatile and handy. Marco

Indentation in TOC
by Devendra Ghate 04 Feb '13

04 Feb '13

Hello, I am trying to indent my section/subsection etc. progressively. I am using *numbercommand* and added *hspace* before the numbers. But the section title is not moved to the right along with the section number and overlaps with it. I tried adding *loffset=2cm* (since all the options of *\framed* are valid for *setuplist*) also, but doesn't seem to have any effect. Please point out the mistake. Regards, Devendra *MWE* \definehspace[myem][2em] \def\secnum#1{\hspace[myem]#1} \setuplist [section] [numbercommand={\secnum}] \starttext \completecontent[alternative=c] \chapter{A} \section{B} \stoptext

Sans Serif Math Font
by Troy Henderson 04 Feb '13

04 Feb '13

Are there any sans serif fonts with matching math (commercial or free) that work "out of the box" (or at least with very little configuration) with ConTeXt? Troy

What is changed?
by H. van der Meer 04 Feb '13

04 Feb '13

The following worked without a hitch: \def\IsNilReturn#1{\edef\tmp{#1}\doifelse{\tmp}{nil}{\color[red]{ERROR}}{\tmp}} \def\formatDuration#1{\ctxlua{ local s = string.gsub("#1","\%D","") local d = tostring(hvdm.time:match(s)) tex.print(string.sub(d,1,2) ~= "0:" and d or string.sub(d,3)) }} \def\FormatDuration#1{\IsNilReturn{\formatDuration{#1}}} Called by something like \FormatDuration{11929} (meaning: 1 hour 19 minutes 29 seconds) Now I get an error in ConTeXt ver: 2013.01.27 21:24 MKIV fmt: 2013.1.28 int: english/english ! LuaTeX error [string "\directlua "]:1: invalid escape sequence near '\%'. \formatDuration ...0:" and d or string.sub(d,3)) } \IsNilReturn #1->\edef \tmp {#1 }\doifelse {\tmp }{nil}{\color [red]{ERROR}}{... Whereas in a previous Context all went well: ConTeXt ver: 2012.05.30 11:26 MKIV fmt: 2013.2.4 int: english/english What did change? Why? And how to repair? Hans van der Meer

Hi, in another thread I got an answer to the question, how to format lines in an environment automatically. Is there a way to get the content of source lines? For example, to save the line content into a variable? Thank you in advance, Ingo

Using \startplacefigure [title=blub, reference=fig:demo, number=no] \externalfigure[example][width=11.2cm] \stopplacefigure how can I set the Title of the image over the image, instead of under the image (that is default) ? Thanks Huseyin
