Math align not working
by Johann Birnick 09 Jan '21

09 Jan '21

Hi there, I noticed that Math align is not working properly. In particular I mean the alignment. For example, the following code \starttext \startformula \startalign[m=2,distance=8em,n=5, align={right,middle,middle,middle,left}] \NC 0 \NC < \NC 2x + 5y \NC < \NC 10 \NC 4 \NC < \NC 3x + y \NC < \NC 9 \NR \NC 3 \NC < \NC 2y + 3z \NC < \NC 15 \NC 10\NC < \NC 8y + 5z \NC < \NC 20 \NR \stopalign \stopformula \stoptext is copied from https://dl.contextgarden.net/myway/mathalign.pdf but doesn't produce the intended result. What's wrong? Best regards, Johann

Some ligatures don't work in latest LMTX
by Jairo A. del Rio 08 Jan '21

08 Jan '21

Hi everyone. The following example works fine with MkIV, but fails with latest LMTX. To be specific, the lam-alif ligature isn't working. Compile with both to see differences. Majalla is a Windows font, so I guess it's available for testing: \mainlanguage[arabic]\definefontfeature [arabic] [mode=node,language=dflt,script=arab, init=yes,medi=yes,fina=yes,isol=yes, liga=yes,dlig=yes,rlig=yes,clig=yes, mark=yes,mkmk=yes,kern=yes,curs=yes]\definefontfamily[main][serif][sakkalmajalla][features=arabic]\setupbodyfont[main]\setupdirections[bidi=global]\starttext أهلاً وسهلاً\stoptext Is that a bug or are more features to be specified? Thank you in advance. Jairo

Display reference number as Roman number
by Rik Kabel 06 Jan '21

06 Jan '21

Hello all, What I thought should be a simple conversion escapes me. I have a reference (created originally via a label defined by \definelabel) that, when referenced as *\in[label]* or *\ref[number][label]* displays a number, and that is how I normally use it. However, I want to display it in one instance as a Roman numeral. *\**Romannumerals{\in[label]}* complains that it is not being fed a number. How can I display the label number in Roman number format in this one instance? -- Rik

mathmatrix and tagging
by Christoph Reller 04 Jan '21

04 Jan '21

Hi, Unfortunately, the following MNWE results in an error when compiled with the latest version of ConTeXt LMTX: \setuptagging[state=start] \definemathmatrix[mymatrix][left={\left(},right={\right)}] \starttext \startformula \startmymatrix \NC A \NC B \NR \stopmymatrix \stopformula \stoptext Omitting "\setuptagging[state=start]" removes the error. A fix would be highly appreciated! Cheers, Christoph

Text editor support via Digestif
by Augusto Stoffel 03 Jan '21

03 Jan '21

Hi all, I have worked a bit on ConTeXt support in the Digestif language server [1], and I think it's pretty usable by this point, so I would like to invite everyone to check it out. Feedback is welcome. Digestif plugs into any editor that support the Language Server Protocol, and provides the usual IDE features: completion (of commands, keyword arguments, references, citations), go to definition, find references, document outline, etc. Among the fancier features is fuzzy-matching, so you can, say, find a citation by typing parts of the title or author names (and get away with using meaningless BibTeX identifiers). The newest (git) version reads the ConTeXt interface files at runtime, so it should be pretty accurate, and also work with third-party packages. It would be cool to also have some integrated documentation, but it looks like ConTeXt (or TeX in general) doesn't have anything of help in this direction currently, right? Another nice thing is that Digestif is a Lua program, and can run on the LuaTeX interpreter with no extra dependencies. On the other hand, I didn't get the change to test it on Windows or editors other than Emacs, although both things should work with minimal adjustments. Let me know if you have any issues. Best, Augusto [1]: https://github.com/astoff/digestif

Ducks in ConTeXt
by Jairo A. del Rio 02 Jan '21

02 Jan '21

Hi everyone! I've recently ported TikZducks to ConTeXt and finally removed TIkZ along the way. So a new module was created. The module is called "metaducks" (lol) and it's essentially a \useMPgraphic{...} with a lot of options, most of them ported from TikZducks. For those not familiar with the package, it draws customized rubber ducks :) I want to include some more, so I'll gladly read any feedback, recommendations and suggestions. Eventually I want it to be a module on its own. The module is already in the ConTeXt Group: https://modules.contextgarden.net/cgi-bin/module.cgi/action=details/id=105 in case anyone wants to give it a try. Here's a minimal example: \usemodule[metaducks] \starttext \ducks[santa=true,mug=true] \stoptext I wish the best for you all. Happy holidays! Cordially, Jairo :)

xrightarrow specific size issue
by Johann Birnick 02 Jan '21

02 Jan '21

Hi there, \starttext $\xrightarrow[50pt]$ \stoptext doesn't work. But it should, right? In the manual \starttext $\xrightarrow[50]$ \stoptext is shown, but that doesn't work either. Best regards, Johann

drop shadows with metapost/ metafun
by Garulfo 02 Jan '21

02 Jan '21

Which process would you advice to add « drop shadows » to any kind of metafun / metapost figures like: picture p; p := textext("MetaPost is fun!") shifted (10cm,10cm); My current understanding of the required steps : 1- fill p with the shadow color 2- write it to an external metapost file (with savebuffer ?) ready for png export (outputformat := "png »;) 3- with lua, os.execute, and imagemagick prepare the shadow - extent the png file with a transparent background, to have room for blurring - blur it 4- import this png in context / Metapost (externalfigure), and center it with p figure 5- shift it according to the desired shadows distance and angle 6- apply the initial bounding box of p to the shadow, draw the shadow, draw the p picture Actually, all this seems long and tedious, and contrasts with the already existing links between MetaPost / MetaFun and cairo + libpng. Thanks again for your help.
