Problem with shading when using rotation (Metapost)

Hi, Sorry to come back with my match problem. In fact, I do not understand why a rotation of 90 influences the degraded color of the ends of the matches. Thank you. Fabrice \starttext \startMPcode def match (expr alpha, pos) = numeric l; l = 4.6cm; picture pic; pic = image ( fill unitsquare xscaled 4cm yscaled 0.2cm withcolor yellow ; fill origin -- (4cm,0) -- (4.1cm,-0.05cm) -- (0.1cm,-0.05cm) -- cycle withcolor(.6yellow + black); draw origin -- (0,0.2cm) -- (4cm,0.2cm) -- (4cm,0) -- (4.1cm,-0.05cm) -- (0.1cm,-0.05cm) -- cycle ; fill fullcircle xyscaled (0.5cm,0.44cm) shifted (4.125cm,0.1cm) shaded withshademethod "circular" withshadefactor 0.75 withshadecolors (white,red);); draw (fullcircle xyscaled (0.5cm,0.44cm) shifted (4.125cm,0.1cm)); draw pic rotated alpha shifted pos; enddef; picture house ; house = image ( match(90,(0,0)); match(0,(0,0)); match(90,(l,0)); match(120,(l,l)); match(60,(0,l));); draw house; \stopMPcode

Re: [NTG-context] Quick question about dual output pdf and epub

One can for instance make the mp images independent (include mp code from a file) and then also make small independent pdf files from them that then can be converted to svg using mutool / mudraw. You can try that concept with \startMPpage some mp code \stopMPage If we're only talking of 'kind of stand alone images' (not backgrounds behind texts and other ornamental mp images) I can think about some mechanism that does that automatic. In the end much is possible (given time and reason) and often not even that hard to do.

Question to installation ConTeXt from TeXlive
by Tomas Hala 01 Mar '20

01 Mar '20

Hi all, when one (eg. student) decides for customizing the Windows installation from TeXlive, 24 items will appear in the group of packages list. Because I have no experience with W. installations, I would like to ask which of them are relevant or possible to use with ConTeXt MkIV (on W.). (The aim is not to install unusable stuff.) Legend: %=I guess no +=I guess yes ?=I am not sure [translated from the Czech version of the Installer] + Additional fonts + ConTeXt etc. + LuaTeX + MetaPost and Metafont + Recommended Fonts + TeXWorks + Auxillary programmes for W. % Additional for LaTeX % Art Fields % Basic LaTeX % Basic (La)TeX % Publishing styles % Recommended LaTeX % Typesetting Games ? Additional formats ? Auxillary programmes for TeX ? Graphics, images, diagrams ? Math, nat. sci., comp. sci. ? Music ? Necessary programmes and files ? PSTricks ? Additional for BibTeX ? SW for graphics and fonts ? XeTeX etc. Thanks in advance. (After completion I can put it on the wiki.) Best wishes, Tomáš

Indenting lists
by Yves Cloutier 29 Feb '20

29 Feb '20

Hello, How does one indent lists to have the same indentation as paragraphs (ex: \small). It should apply to all lists, and so I assume I would need to use \setup<lists?> > The documentation is a bit thin on how I would do this. Any pointers would be appreciated! Regards, yc

ConTeXt Mailing list and DMARC
by Gerben Wierda 29 Feb '20

29 Feb '20

The ConTeXt mailing list is not DMARC compliant. hence, as my MTA now requests DMARC checking, for example texworld(a)laposte.net <mailto:texworld@laposte.net> (and others, but laposte.net <http://laposte.net/> sends me a forensic report) doesn’t get my posts to the ConTeXt mailing list as laporte.net conforms to DMARC. To be DMARC compliant the ConTeXt mailing list should either not change the content of the message (add a footer, which breaks the signature) or use other means to keep DMARC working. If not DMARC compliant, more and more subscribers will not get the messages sent to the list. G

How do I tell mtxrun not to open the pdf or to open it differently?
by Gerben Wierda 29 Feb '20

29 Feb '20

Thanks. Found those. I am looking how to tell mtxrun not to open some WINE-based Windows PDF previewer but something else. Using —autopdf it now ends with mtx-context | pdfview methods: auto default okular pdfxcview sumatra, current method: sumatra (directives_pdfview_method) pdfview | command: wine "sumatrapdf.exe" -reuse-instance -bg-color 0xCCCCCC "test.pdf" 1>/dev/null 2>/dev/null & mtx-context | pdfview overhead: 0.003 seconds But I don’t use that and the man page for mtxrun doesn’t help me (besides, the man page I get is from MacTeX/TeXLive and probably not form the latest standalone ConTeXt. mtxrun —help doesn’t help either. So, where do I find it? There is no mtxrun.pdf manual. (I am getting a real deja-vu on the state of ConTeXt documentation, it’s probably there these days but it is ‘unfindable’ and seems incomplete. E.g. install.sh shows a flag —autopdf for mtxrun (probably the first time you get an instruction on the use f mtxrun) which is then not mentioned in mtxrun —help or mentioned in the man page (in MacTeX). Wiki seems to end in 2011. Etc. This kind of experience is (again) very frustrating, I must say. It is my main stumbling block for actually using ConTeXt) G > On 29 Feb 2020, at 12:35, mf <massifr(a)fastwebnet.it> wrote: > > Il 29/02/20 12:10, Gerben Wierda ha scritto: >> Is there not a simple place to get all the up-to-date documentation? > > If you install ConTeXt from > > http://www.pragma-ade.nl/install.htm > > in the installation tree you'll find docs under > > tex/texmf-context/doc/context/documents/ > > There you'll always find the docs at their last revision. > > Massi

Up-to-date documentation / tutorials. Where?
by Gerben Wierda 29 Feb '20

29 Feb '20

Hello community, I have been (unsuccessfully) hunting for up-to-date tutorials/documentation on ConTeXt/LuaTeX/METAPOST. What I find is sites that for instance end in 2011. documentation that is from 2013, or on Pragme-ADE a show-man.pdf PDF with an overview of documentation that doesn’t open any underlying document. Is there not a simple place to get all the up-to-date documentation? G

Some questions regarding math typesetting
by TeXnician 29 Feb '20

29 Feb '20

Dear list, while doing some math typesetting, I have found the following features not working in LMTX: 1. Non-displaystyle operators are simply not shown (try \sum or \lim in text or scriptstyle). This works in MkIV (and iirc in LMTX versions from before november). 2. \underbrace{x}_{y} stopped working. It produces an underbrace but the subscript is not centered below the brace. It will show up as right subscript. This works in MkIV. 3. \startformulas does not allow numbering formulas because the number will run into the next column. I have posted this at https://tex.stackexchange.com/questions/518262/context-number-formulas-side… and Henri Menke tested that it broke in 2017. Aditya Mahajan mentioned that it is a bug. For the upper two cases: Is anything wrong with my LMTX installation or did I miss some upgrade instructions for math in LMTX? Many thanks for an answer.

Last names in citations
by Fulvio Satta 28 Feb '20

28 Feb '20

Hi, probably my question is not a very hard one but I don't find a way to do what I'm trying to do. If I use \cite[authoryears] ConTeXt uses last names in the citation. That's what I want, but I want to use another style for my task, that I defined this way: \definebtx[aps:cite:margin][authorconversion=normalshort] \startsetups btx:aps:cite:margin \texdefinition{btx:aps:title} \texdefinition{btx:aps:author} \doiftextelse\currentbtxrighttext{ \currentbtxrighttext } { \removeunwantedspaces \removepunctuation } this works and is perfect for my style, but I obtain the full names, and not just the last names. How can I obtain something similar to the citation I'm using, but with just last names?
