MetaPost Function Grapher
by Troy Henderson 23 Feb '13

23 Feb '13

The MetaPost output from my Function Grapher http://www.tlhiv.org/mpgraph/ is now available in ConTeXt format. This can be illustrated by choosing a graph type and selecting an example from one of the Example buttons. Once the graph is drawn, the ConTeXt source can be downloaded using the "Download" drop-down box. Simply executing `context mpgraph.tex` should produce the same graph viewed on the website in PDF. If you see any bugs, feel free to let me know. Troy Henderson

Dear all, While trying to continue itemized list as follows: \starttext \startitemize[1,unpacked] \item First item \startitemize[a,unpacked] \item First sub-item \item Second sub-item \stopitemize \item Second item \startitemize[continue] \item Third sub-item \item Fourth sub-item \stopitemize \stopitemize \stoptext What I get is the following: * First item a. First sub-item b. Second sub-item * Second item a. Third sub-item b. Fourth sub-item While I was expecting to receive: * First item a. First sub-item b. Second sub-item * Second item c. Third sub-item d. Fourth sub-item I use FreeBSD 9.1 and the output of context --version is: mtx-context | ConTeXt Process Management 0.60 mtx-context | mtx-context | main context file: /usr/local/context/tex/texmf-context/tex/context/base/context.mkiv mtx-context | current version: 2013.02.18 15:46 Is there something I do wrong?

[***SPAM***] Question about current ConTeXt with XeTeX
by hwitloc＠gmail.com 22 Feb '13

22 Feb '13

I just read in contextgarden.net the following: "Note that XeTeX uses mkii and LuaTeX uses mkiv ; in principle mkii is frozen so new features and improvements will only happen in mkiv." I use the ConTeXt which comes in TEXLIVE 2012, which I assume uses Mark IV. Does that mean that I can not use this version of ConTeXt with XeteX which also comes packaged in TEXLIVE? Regards

pgfplots in newest beta
by Malte Harder 22 Feb '13

22 Feb '13

Hi list, I've got a problem with the latest beta and pgfplots. It already happens when the module is loaded and also with a minimal file testing pgfplots. Output is attached below. Is this is a known problem that has a workaround or will be fixed in the future? Not a big problem for me, I guess I'll just downgrade to a working version in the meantime.

simpleslides bug?
by Zhichu Chen 21 Feb '13

21 Feb '13

Maybe this is my fault. The simpleslides module works just fine these days and I "accidentally" updated the ConTeXt to the latest version: context --version mtx-context | ConTeXt Process Management 0.60 mtx-context | mtx-context | main context file: /opt/context/tex/texmf-context/tex/context/base/context.mkiv mtx-context | current version: 2013.02.13 18:06 and this small piece of code failed to compile: \usemodule[simpleslides][style=BigNumber] \starttext \SlideTitle{Test} test \stoptext and gave me the following error message: simpleslides > loading Big Number style system > command \NormalHeight is already defined system > command \NormalWidth is already defined system > command \PictureFrameHeight is already defined system > command \PictureFrameWidth is already defined colors > rgb color space is supported colors > cmyk color space is supported )) fonts > bodyfont 24.0414pt is defined (can better be done global) metapost > initializing instance 'metafun' using format 'metafun' metapost > loading 'metafun': /opt/context/tex/texmf-context/metapost/context/base/metafun.mpiv, using method: default metapost > initializing number mode "scaled" *** glibc detected *** luatex: double free or corruption (fasttop): 0x00000000057da5a0 *** ======= Backtrace: ========= /lib64/libc.so.6(+0x7d836)[0x7ff8ff104836] luatex(mp_free_node+0x3b)[0x6406fb] luatex[0x66637c] luatex[0x6743be] luatex[0x6724b8] luatex[0x670210] there're more and if it is important for the diagnostics please let me know and I will provide the whole message which I thought was relevant.

extras in \cite
by Devendra Ghate 21 Feb '13

21 Feb '13

Hello Everyone, A while back Aditya provided a patch for using *alternative=authornum* in *\cite*. The patch adds et al. for the cases with more than two authors. I have been using it without a hitch since then. However, today I tried to use *extras* option with this patch and it won't work. The MWE works for *alternative=apa* and *alternative=num* Please let me know if this can be rectified. Regards, Devendra *MWE* \setupbibtex[database={bib}] \unprotect \def\dobibauthornumref#1% {\bibinsertrefsep \doifbibreferencefoundelse{#1} {\begingroup \cite[left=,right=,alternative=author][#1]% \bibalternative\c!inbetween \cite[num][#1]% \endgroup} {}} \protect \starttext \cite[alternative=authornum,extras={,\S 5.1}][citation1] \placepublications \stoptext ----------- bib.bib ----------- @article{citation1, title = {Kernel independent component analysis}, author = {Bach, F.

Quick slide templates
by Kumar Appaiah 20 Feb '13

20 Feb '13

Dear ConTeXt list, This could be more of a style and TeX question than a ConTeXt question. Nevertheles: I am making a presentation that involves some simple animations. The way I make those animations is by: 1. Stopping page numbering. 2. Flipping through the same slide repeated, but with img0, img1, img2 etc. 3. Start page numbering. The problem with my naïve approach of repeating slides is that fixing a spelling error or making changes implies that I have to do it several times for an “animated” slide, and is error-prone. Could you point me to a way by which I can make a slide something like a “function” whose argument is the image, and calling it creates that slide with an image? FWIW, I use texexec --xtx, but I am guessing a LuaTeX solution would be simpler. The XeTeX solution is what I am not able to find now. Thanks! Kumar -- Kumar Appaiah

HTML output
by Troy Henderson 20 Feb '13

20 Feb '13

I would like to convert my ConTeXt document to both PDF and "plain" HTML. I need plain HTML output (i.e., not XML or XHTML) because my institution's web based management software allows me to copy/paste plain HTML snippets but not XML or XHTML. Is it possible for ConTeXt to output HTML so that the result looks as close to the PDF output as possible? Troy Henderson
