Interpreting MathJax HTML in MKIV
by Mojca Miklavec 14 Oct '11

14 Oct '11

Hello, I would like to manually create some HTML which would be displayed nicely in both HTML and PDF (using MKIV for conversion from HTML). To a certain degree I'm able to fake mathematics with ax2 + bx + c = 0 where signals TeX to use \mathematics{...} and signals web browser that the letter has to be displayed in italic (I could use class="math", but this would also make numbers italic). But this is very cumbersome to write. MathJax offers an excellent way to enter math formulas in an easy way (see attached HTML), but I'm not sure how I could convince the XML parser to treat contents literally. Any ideas? Thank you very much, Mojca

nice friends-book with ConText
by Jan Heinen 14 Oct '11

14 Oct '11

Hello, I hope the answer is easier than the question :-) I am a ConText-Newby and am struggeling with the huge amount of ConText-commands. I want to make a little book with infos and fotos of our friends - and I am afraid, the nice layout I have in mind is to complicated or impossible with ConText - at least for me. The book will have 40 pages and every page with the same layout. I have posted the layout I want to use as a .png to http://www.imagebanana.com/view/f4o3un2c/Entwurffriends.png Which ConText-commands do I need for this layout? I tried \inmargin - without success. \definelayer and \setlayerframed worked (a littlebit) - though the running text (beneath the headline) runs through the layer. What seems the easiest way? layers, columns, ? Maybe someone here has a little example which I can finetune. Which hints can be given? I would be very happy about a rough structure of the context-code - I think then I am able to do the finetuning with the manuals. I am working with Linux - so Indesign is no alternative for me :-) Regards Jannis

Error in simpleslides style Swoosh
by Marco 13 Oct '11

13 Oct '11

Hi, the presentation template “Swoosh” behaves weird and triggers an error. • Use the example file generic-talk-15min-45min.tex • Comment “style=BigNumber,” • Uncomment “style=Swoosh,” The log file is attached. Workaround: First processing the file using another style, then processing using “Swoosh” does not trigger the error. Regards Marco Patzer

Hello, in some rare circumstances the enabled italic correction (\setupitaliccorrection[always]) cause the following error: /tex/texmf-context/tex/context/base/typo-itc.lua:99: attempt to index local 'cd' (a nil value) In needed I will try to make a minimal example. I’ve asked it already, bun since I got no answer … Would it be possible to expand the the cross referencing mechanism, so that it would be possible to store the component files in a subfolder? Here is a test: http://www.ntg.nl/pipermail/ntg-context/2011/062335.html Thanks in advance Andreas

Setting style and color attributes of label in metapost
by Aditya Mahajan 13 Oct '11

13 Oct '11

I am writing a module which uses metapost in the background for drawing. I wanted to create an interface for setting the style and color of metapost labels but using \doset...attributes is not working. Here is an example: \definenamespace [test] [style=yes, name=test, command=yes, setup=yes] \definetest [blue] [color=blue, text=Blue] \definetest [two] [blue] [style=\bold, text=Two] \starttext \edef\currenttest{two} \startMPdrawing label.lft(\sometxt{\dosettestattributes{style}{color} \testparameter{text}}, (0,0)) ; \stopMPdrawing \edef\currenttest{blue} \startMPdrawing label.lft(\sometxt{\dosettestattributes{color}{style} \testparameter{text}}, (2cm,0)) ; \stopMPdrawing \MPdrawingdonetrue\getMPdrawing \stoptext Notice that the first label has the same style as the last label. This is happening because \doset..attributes is defined as an unexpandable macro. I can get around this by setting the value of \currenttest inside the \sometxt{...} argument. Something like: \def\dosometxt#1#2% {\normaldosometxt{#1}% {\def\noexpand\letterbackslash currenttest{\currenttest #2}}} Surely, there should be a more direct way of achieving this? Aditya

Plotting a graph of a function f, like f(x) = e^x, with MetaPost
by Paul Menzel 13 Oct '11

13 Oct '11

Dear ConTeXt folks, I finally chose MetaPost/MetaFun [1] because of the native integration with ConTeXt and hopefully easy font handling. I want to use that throughout my document. Of course I hit the first problem. Wanting to draw a “simple” function f like f(x) = e^x, seems hard to accomplish. I guess I should stress that MetaPost does not have a high accuracy so it might not be the best solution [5]. There seem to be quite a lot of solutions (mostly macros) on the Web for this problem so I am wondering if one of them is integrated in MetaFun. Here are some of my findings. 1. Reading about the graph package by John D. Hobby [2] and which is also included in ConTeXt [3]. Especially I liked the automatic coordinate systems. The package seems to only be able to plot graphs with data points saved in files. So one solution would be to manually create data files with data points of the relevant function. 2. There is an example in the Drexel Physics Wiki [4]. 3. Anthony Phan has also created some macros in his `mps` [5 (currently not accessible)]. 4. André Heck uses the macro packages `courbes` and `grille` from Jean-Michel Sarlat to show some nice examples in his tutorial »Learning Metapost by Doing« [6]. So what do you suggest? Thanks, Paul [1] http://www.ntg.nl/pipermail/ntg-context/2011/058527.html [2] http://tug.org/docs/metapost/mpgraph.pdf [3] http://wiki.contextgarden.net/Metapost [4] http://einstein.drexel.edu/liki/index.php/Metapost#Graphing_Functions [5] http://www-math.univ-poitiers.fr/~phan/downloads/metapost/statsman.pdf [6] http://staff.science.uva.nl/~heck/Courses/mptut.pdf

metafun manual: Typo on page 382, section 9.3 drawing functions
by Paul Menzel 13 Oct '11

13 Oct '11

Dear ConTeXt folks, I am sorry to bother you with these kind of messages. On page 382 of the Metafun manual [1] (Fr 08 Okt 2010 13:44:26 CEST) it should be In this case the pairs (log(x), x) and … so (log(x), x) instead of (x, x). Thanks, Paul [1] http://www.pragma-ade.com/general/manuals/metafun-s.pdf

Solution to a "superscript" problem?
by Otso Helenius 13 Oct '11

13 Oct '11

Hello, I've been trying to come up with a few methods to add definitions to text with the help of the metafun and context manuals. The first method adds the definition as sort of a "superscript" on top of the word, and the second one marks multiple words with a curly bracket and adds the definition on top of the tip of the bracket. Here is the (ugly and hackish) code: \startuniqueMPgraphic{defline} path p; p:=(0,0)..controls (0,1) and (1,1)..(1,1)--(6,1)..controls(7,1) and (7,1)..(7,2)--(7,2)..controls(7,1) and (7,1)..(8,1)--(13,1)..controls(13,1) and (14,1)..(14,0); draw (0,0)--(0,12pt) withcolor white; draw p xscaled (\overlaywidth/15) yscaled 5 shifted (0,9mm) withpen pencircle scaled 0.25mm withcolor red; \stopuniqueMPgraphic \defineoverlay[curlybracket][\includeMPgraphic{defline}] \def\sentencedef[#1][#2]{\setbox\scratchbox=\hbox{#2}\hbox to \the\wd\scratchbox{\cbox{\hbox{\tfxx\color[red] #1}\\\hbox{\framed[background=curlybracket,frame=off]{#2}}}}} \def\worddef[#1][#2]{\setbox\scratchbox=\hbox{#2}\hbox to \the\wd\scratchbox{\cbox{\hbox{\rotate[rotation=25]{\tfxx\color[red] #1}}\\\hbox{#2}}}} \starttext \hbox{\worddef[def1][Lorem] ipsum \worddef[def2][dolor] sit \worddef[def3][amet] consectetur \worddef[def4][adipiscing] elit.} \hbox{\sentencedef[def5][Lorem ipsum] dolor sit \sentencedef[def6][amet consectetur] adipiscing elit.} \stoptext I haven't figured a way to add the curly bracket graphic neatly nor position the definition correctly on top of it. I would be very interested in any advice regarding these two functions and how to rewrite both of them in a more elegant way.

beta
by Hans Hagen 13 Oct '11

13 Oct '11

Hi, I uploaded a new beta. There are a few new things and some changes: - The flow chart module has been rewritten for mkiv and cf Wili it does a decent job so I've replaced the old one. This is the one that can be extended (discussed at the context conference). - I'm rewriting stepcharts (something I need myself) but that's work in progress. Here the functionality will change a bit (no problem as I never noticed any other usage). The manual will also be updated. == There is an experimental new s-fnt-35.mkiv module that can be used as: \usemodule[fnt-35,art-01] \setupbodyfont [cambria] \starttext \ctxlua{moduledata.fonts.show_a_lot("Cambria")} \stoptext It probably needs to be improved. Users are welcome to submit additional (language related) sample alphabets etc. It might also become an option for mtx-fonts.lua == There has been a change in storing positional info in the tuc file. No big deal, just another format. == There has been a fix in otf contextual stuff ... for Idris (so that he can finish the context book sooner). == There are some new commands: \startdocument and \stopdocument. Copied from mag-1101: \starttyping \startdocument[settings] structured content \stopdocument \stoptyping The settings are key|/|value pairs and the values can be retrieved using: \starttyping \documentvariable{key} \stoptyping You can set \type {before} and \type {after} parameters and by default these are set up as follows: \starttyping \setvariables [document] [before=\directsetup{document:start}, after=\directsetup{document:stop}] \stoptyping You can for instance define these setups to generate a title page (using document variables) and a colophon page. In the future more functionality might be added. == Yet another new feature is automatic italic correction. There will be an article about it (first version ready), maybe in the conference proceedings as it's a follow up on the conference. Quick howto: \definefontfeature[default][default][itlc=yes] It is enabled with: \setupitaliccorrection[always] % or 'text' or 'none' Or (bit more efficient): \setupitaliccorrection[always,global] or even: \definefontfeature[default][default][itlc=yes,notextitalics=yes] to get rid of \/ too. (we might opt for \/ being just /). Thomas and I will play with additional functonality (range support for fonts that have somewhat italic properties like greek). == Of course there are a couple of patches and for sure some new bugs (or missing files).
