What I have in mind (others could complete) is in particular a way to plot the set of (x,y) such that f(x,y)=0 for some given function f and some rectangle in x and y. I made some plots with Mathematica http://www.maths.lth.se/matematiklth/personal/mickep/Contour.pdf (too big for the list) The first plot shows a difficulty with a contour plot, namely intersections. In the second one I added points, and it looks better. In the third plot I have not specified that the expression should be equal to 0. Then Mathematica plots the curves f(x,y)=C for various values of C. In the background it adds a density plot (i.e. a mesh with different colours for different values of the function. In the fourth plot, the regionplot, the pairs (x,y) for which f(x,y)<0 are marked. This is also very useful. In the fifth plot there is only the densityplot, with different colors for different values of f. I don't know how difficult it is to implement this kind of graphics. Also, it could be useful to be able to input the equation f(x,y)=0 and to receive the curves as MetaPost paths. It seems that one can do contour plots with the help of lua if that is something that helps ( http://franko.github.io/graph-toolkit/contour.html) Anything would be better than nothing, and I'm more than happy to test. > > > 3) (small) The possibility to have arrows in coordinate axes.

\setupcolumnsetlines does not work again
by Sytse Knypstra 19 Aug '19

19 Aug '19

I thought I understood the mechanism, but I found another instance where \setupcolumnsetlines does not give the desired result: %%%%%%%%%%% \definecolumnset[Two][n=2] \starttext Test %\page \setupcolumnsetlines[Two][1][1][9] \startcolumnset[Two] \input knuth \stopcolumnset \setupcolumnsetlines[Two][1][1][9] \startcolumnset[Two] \input knuth \stopcolumnset \stoptext %%%%%%%%%%% This setup gives indeed a balanced first page and an unbalanced second page. But if the fourth line (\page) is uncommented, the second output page is unbalanced and the third page is balanced. So the mechanism is therefore more complicated than > only if the first columnset extends to more than one page > the next \setupcolumnsetlines will work properly. What is the extended rule? If this intended behaviour, what is the reason behind it?

Bug in lmtx with \Bbb
by Otared Kavian 19 Aug '19

Hi Hans, It seems that there is a bug in the handling of Blackboard Bold, in the latest lmtx (version 2019.08.02 19:40). The following gives the attached PDF file. However the same file typesets correctly in the latest mkiv beta. Thanks for your attention: OK \starttext The set of integers is denoted ${\Bbb N}$. \stoptext

Bug in lmtx in display mathmode
by Otared Kavian 19 Aug '19

19 Aug '19

Hi Hans, I have a long document which typesets correctly with mkiv, but I get a (cryptic for me…) fatal error message when I try to typeset it in lmtx: ! error: (nodes): trying to delete an attribute reference of a non attribute list node 4476mtx-context | fatal error: return code: 256 I could finally find the origin of the error, which is exposed in the following example: if you comment out the part from \startformula ... \stopformula, the file typesets correctly. But with this part, one gets the above error message, the culprit being \liminfbar which is defined in the first line. Note that \liminfbar is accepted when it is inline math. Best regards: OK %%% begin bug-math-lmtx.tex \definemathcommand[liminfbar][limop] {\underline{\mfunctionlabeltext{lim}}} \starttext If $(u_{n})_{n}$ is a sequence of real numbers, we define its {\it limit inferior}, denoted $\liminfbar$ by setting: \startformula a_{n} := \inf\{u_{k} \; ; \; k \geq n \}, \qquad\text{and then}\quad \liminfbar_{n\to\infty} u_{n} := \sup_{n \geq 1} a_{n}. \stopformula \stoptext %%% end bug-math-lmtx.tex

ConTeXt Meeting 2019 registration details and tshirts
by Taco Hoekwater 17 Aug '19

17 Aug '19

Hi all, Because I received some email requests on whether registration is still open for the ConTeXt meeting in Bassenge and what to do about day visits et cetera, here is the nitty gritty on that: * As of today, there is room left for 10 extra participants, so late registrations are still possible. * Nevertheless, if you are certain you want to attend; better make sure to register shortly. You’ll be sorry if there is a sudden influx of dozens of new ConTeXt users from CCCamp and registrations have to be closed because of lack of room ;) * There are no single rooms available any more. * Registration will be closed on Sunday September 8 even if we are not full up by then, as some dinner ingredients need to be ordered in advance. * Day visits and partial attendance are both possible, but must be announced before September 8 if you want to stay for dinner and/or overnight (see above). Note further that overnight stays are subject to availability of empty beds. Fees for such visits: Lunch: €10; Dinner: €30; Overnight stay: €40. * The registration form can be used for day visits and partial attendance as well as for “normal” registration: https://meeting.contextgarden.net/2019/register.shtml but emailing me personally works fine as well. I hope that covers everything. Feel free to contact me directly if I forgot something. Then, there is a note on T-shirts needed: At the moment, we do not have enough registrations for a balanced budget. This means we had to cancel the free conference T-shirt, sorry! However, all is not lost: Pavneet Arora will be producing T-shirts for those that are willing to pay cash on delivery at Bassenge. Expected price is around €15 per shirt. Because of production times, reservation is both required and urgent. The production order should be made next Monday or Tuesday at the latest, so if you want one (or more) of the T-shirts, decide quickly! Pavneet will probably post a screenshot of the final logo design later today, and I am sure he will answer any additional questions you may have. Best wishes, Taco

The odd semantics of \begincsname
by Henri Menke 17 Aug '19

17 Aug '19

Dear list, According to the LuaTeX documentation: “The \begincsname primitive is like \csname but doesn’t create a relaxed equivalent when there is no such name.” I thought it would be possible to use this fact to skip the \relax-ed definition when \def-ining a new control sequence, but the following MWE fails with \inaccessible: \expandafter\gdef\csname yes\endcsname{} \expandafter\gdef\begincsname no\endcsname{} \bye Is this a bug or is this behaviour intended? Could this be fixed by making manufacture_csname aware whether it is in a def_cmd context or not? Cheers, Henri

radiobuttons
by Henning Hraban Ramm 16 Aug '19

16 Aug '19

Hi, coming back to an old form project I find that something changed WRT to form fields. For one, some fields appear smaller and shifted upwards – I managed to fix that with setups. What I can’t change is behaviour of radiobuttons: if I click one, all rbs of one group activate, and I can’t deactivate them any more. In my project all of the fields are duplicated on other pages, and while all other fields’ contents get copied, it doesn’t work for radiobuttons; my minimal example unfortunately can’t show that. \setupinteraction[state=start] \setupfield[MMradio][ option=printable, frame=overlay, corner=round, height=1em, width=1em, align=bottom, ] \definefield[chooseTeX][radio][MMradio][rbContext,rbLatex,rbOther][rbContext] \definesubfield[rbContext][][] \definesubfield[rbLatex][][] \definesubfield[rbOther][][] \starttext I want to use \field[rbContext] \CONTEXT\ \field[rbLatex] \LaTeX\ \field[rbOther] other. \page Just to confirm: I want to use \field[rbContext] \CONTEXT\ \field[rbLatex] \LaTeX\ \field[rbOther] other. \stoptext Greetlings, Hraban

OSFONTDIR is like other PATH variables, it can contain several paths, separated by ; (at least on Linux and OSX, maybe it’s : on Windows). My OSFONTDIR is rather lengthy to include my collections of commercial and free fonts (beware, that makes ConTeXt slow).

OSFONTDIR and Windows 10
by Huseyin Özoguz 15 Aug '19

15 Aug '19

Hello, I just moved to Win 10 (coming from Win 7) with a fresh system and installed Context. My problem: The manual installed fonts are not stored in "Windows/Font" like before, but in "AppData/Local/Microsoft/Windows/Fonts" – the default Fonts, which came with windows, are still there in Windows/Font. If I change OSFONTDIR to the new path and execute "mtxrun --script font --reload" after that, the new fonts are found by Context, but that seems no good way, because now the default-fonts are not found. How to solve this situation? How can I prevent Win10 from installing manual installed fonts into this other path and instead install it into "Windows/Font"directly? (Other programs like Corel etc. have no problems finding those other fonts, regardles of there location or OSFONTDIR.) Another solution: Give Context two pathes to look for fonts, is that possible?

ConTeXt Group Newsletter August 2019
by Taco Hoekwater 14 Aug '19

14 Aug '19

In this newsletter: * 2018 journal progress * ConTeXt Meeting updates * Chaos Communication Camp * Board elections * Becoming a CG member = 2018 journal progress = Our next ConTeXt Group journal issue is printed! Printed copies will reside below my desk until the meeting. The Table of Contents is online at: https://articles.contextgarden.net/journal/2018.html The PDFs are not yet publicly available but current CG Members can send me an email for an advance copy of any of the article PDFs. If you are not a member, you will have to wait until summer 2020. = ConTeXt Meeting updates = There is now a preliminary programme available on the meeting website (address below). Due to financial considerations, this will likely be our last visit to ’t Sjetootje. If you would like to visit the castle with us, you should register now :) = ConTeXt Meeting blurb = If you have not registered yet, please consider joining us at ’t Sjetootje, Bassenge-Boirs, Belgium on September 16–21, 2019. The ConTeXt meeting is an excellent way to get help with any problems you may have in ConTeXt, to learn about future directions of ConTeXt and LuaTeX, or just to talk and have a drink with other ConTeXt users. You do not have to be a ConTeXt Group member to attend the meeting, but members do get a meeting fees discount worth more than the CG membership fees for a year. In fact, if you attend for the very first time, there is an extra discount for that as well. For registration and other information, see the website at https://meeting.contextgarden.net/2019 The 13th ConTeXt Meeting is sponsored by Dante e.V (www.dante.de) and NTG (www.ntg.nl) as well as by Pragma ADE (Hans & Ton) and Bittext (Taco). We are very grateful to all our sponsors! = Chaos Communication Camp = CG Board member Henning Hraban Ramm is representing the ConTeXt community at the Chaos Communication Camp 2019 in the 'LaTeX Village’ (set up in conjunction with Dante e.V.) https://events.ccc.de/camp/2019/wiki/Village:LaTeX If any of you are in the neighbourhood of Ziegeleipark Mildenberg, Zehdenick, Germany between August 21 and 25, I am sure he would love to see some visitors (Zehdenick is about 60km north of Berlin). = Board elections = The ConTeXt meeting is also the location of the annual CG membership meeting. This year, no less than four board members are forced to resign according to the bylaws. We are looking for CG members to help fill those spots in the board. If you are interested in joining the CG board, please send a message to any of the current board members and we will get in touch with you. We can really use the help! Our previous newsletter already provided one tentative new board member, but ideally we would like at least one more candidate. = Becoming a CG member = Our official stated purpose: * to promote the ConTeXt typographic system; * provide its users with infrastructure and information; * support its development; * provide a platform for discussion of quality automated typography; * serve as a meeting place for people who want the best possible typography for the languages and writings of the world; * organise congresses and trainings for users and ConTeXt developers to meet; * provide financial support to those involved in documentation and ConTeXt development, including through their participation in conferences; * produce and sell printed materials on ConTeXt; * sell advertising items for ConTeXt. The more members we have, the more we can do. If you are not a member already, please consider registering at https://group.contextgarden.net/register.shtml Membership fees are €40 per year for normal members, €20 for students, and €200 for institutions and corporations. = That’s all for now = Keep happy ConTeXting!

Convert SVG to MetaPost
by Jon Wong 13 Aug '19

13 Aug '19

Hi all, Is it possible to convert SVG to MetaPost? Currently, I have Bash scripts in my workflow to invoke Inkscape (converting SVG to PDF). I don’t like to allow shell access to TeX. If I can convert SVG to MetaPost, I will gladly Git-track MetaPost files instead of SVG files. That will do away with having to convert SVG into PDF (via Inkscape). Regards Jon

Typesetting hebrew in a table...
by Willi Egger 12 Aug '19

12 Aug '19

Hi all, my brother is studying Ifrith and wants to have a dictionary. The idea is to typeset left German and right Ifrith in a /bTABLE…\eTABLE environment. When trying to typeset the Ifrith text is not broken into lines correctly i.e. it is leaping into the cell reserved for the German text. — How to correct this behaviour? I attach a rather minimal sample. Kind regards! Willi

texexec is deprecated?
by Jon Wong 12 Aug '19

12 Aug '19

Hi all, I did a quick standalone install of Mark IV: ```shell mkdir ~/context cd ~/context wget http://minimals.contextgarden.net/setup/first-setup.sh sh first-setup.sh --modules=all --context=current --engine=luatex’) ``` Set the correct paths and env in `~/.bashrc': ```shell # Add ConTeXt platform=osx-64 PATH=~/context/bin:~/context/tex/texmf-$platform/bin:$PATH source ~/context/tex/setuptex export PATH ``` (By the way, the latest lmtx installer is missing the `setuptex' file.) I was able to use `context’ but not `texexec’. The latter (`texexec —pdf test.tex’) tells me that some format file (`cont-en.fmt’) can’t be found. Is `texexec’ obsolete? The 2013 ConTeXt manual still uses it, though. Regards Jon

Wrong MetaPost text output
by Henri Menke 11 Aug '19

Dear devs, There seems to be a bug in the MetaPost integration of ConTeXt. The MWE below should produce three different labels “dummy foo bar” but instead produces “bar bar bar”. The same example works correctly in plain MetaPost.

white space after a float in a column
by Sytse Knypstra＠home.nl 10 Aug '19

10 Aug '19

Dear list members, I am struggling with floats in a two-column layout. I understand that there are three up-to-date mechanisms for columns: columnsets, pagecolumns and pagegrids. However, in neither setup I succeed in producing some extra vertical whitespace after the float if a caption is omitted (i.e. location=none in \setupcaption). My example:   \definepapersize[square21][width=21cm,height=21cm]  \setuppapersize[square21][square21]  \definecolumnset[Two][n=2]  \setupcolumnset[Two]  \setupcaption[intermezzo][location=none,spaceafter=1cm]  % no value for spaceafter seems to work \setuptolerance[verytolerant,stretch]  \setupframedtexts[frame=on,corner=round,width=local]  \setuplayout[grid=yes]  \starttext  \startcolumnset[Two]  \input knuth \par   \placeintermezzo[bottom][]{}  \startframedtext  \input tufte \par  \stopframedtext   \input knuth \par  \stopcolumnset \stoptext If 'columnset' is replaced everywhere by 'pagecolumns' or by 'pagegrid' through a find-and-replace operation, the result remains identical. Is it possible to insert more vertical white space after the intermezzo? A secondary remark: \placeintermezzo always puts the framed text at the top of the next column, no matter whether the parameter is top or bottom. But this is not a big deal. Sytse Knypstra

[feature] update
by Floris van Manen 09 Aug '19

09 Aug '19

I do a daily update of the context distribution using the command sh ./first-setup.sh --modules=all --engine=luatex This works well, but is rather verbose on the screen. Would it be possible to have a less verbose version? Or that the script could check some kind of a checksum before deciding to download all data? Or download only part of the data (saving on some carbon footprint ;-) Thanks. .Floris

XML/HTML output of Math
by Atsuhito Kohda 09 Aug '19

09 Aug '19

Hi all, I used to compile a beamer file with LuaLaTeX to generate a PDF for presentation then convert the beamer file to XHTML with LaTeXML for Web page. Recently I begin to use ConTeXt so I try to get a PDF for presentation and also XML/HTML output from a single ConTeXt file. I have a few questions about XML/HTML output of Math. 1. In case inline math mode with \displaystyle, we get wrong output of "\int_a^b"; lower limit and upper limit are interchanged and further "b" is a bit larger and an integral symbol is rather small. (It looks "\displaystyle" is not effective, e.g see "\frac".) In case display math mode, we get very weird output of "\int_a^b". It is difficult to explain how weird it is but something like an output of "b_{\int}^a". Please check an attatched sample. We get the similar kind of weird output of "\sum_{n=0}^{\infty}". Due to these, it is impossible to use XML/HTML output of ConTeXt in real use. 2. \math{\Vmatrix{\vI, \vj, \vk; a_{1}, a_{2}, a_{3}; b_{1}, b_{2}, b_{3}}} \vI, \vj, \vk are disappeared in xml/html output. What happend? BTW, if we put "a" (or any alphabet?) in fron of \vI, then we get every elements (but of course we get unnecessary "a" also). ------------- bSample \setupbackend[export=yes] \definemathmatrix[vmatrix][matrix:bars] [simplecommand=Vmatrix] \define[1]\vsym{\text{\math{\bi #1}}} \define\vI{\vsym{i}} % \define\vi{\vsym{i}} \define\vj{\vsym{j}} \define\vk{\vsym{k}} \starttext A simple math. \m{y=\sin x}, \m{\displaystyle y=\frac{\log x}{x}}, \m{\mathbf{A+B=C}}, \m{\mathbb{R}}, \m{\mathfrak{A}}, \m{\mathcal{S}}, A bit complex math. \m{\displaystyle\int_{a}^{b}x\sin x\,dx=-[x\cos x]_{a}^{b}+\int_{a}^{b}\cos x\,dx} \startformula \int_{a}^{b}x\sin x\,dx=-[x\cos x]_{a}^{b}+\int_{a}^{b}\cos x\,dx \stopformula \m{\displaystyle\sum_{n=0}^{\infty}\frac{x^n}{n!}} \startformula \sum_{n=0}^{\infty}\frac{x^n}{n!} \stopformula \math{\Vmatrix{\vI, \vj, \vk; a_{1}, a_{2}, a_{3}; b_{1}, b_{2}, b_{3}}} \math{\Vmatrix{a\vI, \vj, \vk; a_{1}, a_{2}, a_{3}; b_{1}, b_{2}, b_{3}}} \stoptext ------------- eSample Thanks in advance.

Nested Column Layout
by Walter Mays 06 Aug '19

06 Aug '19

Hello all, I am trying to lay out a page that has a 2/3 column split, and then nest another set of 3 columns inside the larger of the two outer columns. In case that's not clear, I've attached a PNG that shows approximately what I would like to achieve. Here's what I've tried: ``` \defineparagraphs[TwoThirds][n=2] \setupparagraphs[TwoThirds][1][width=0.33\textwidth] \starttext \startTwoThirds \input tufte \nextTwoThirds \input tufte \startcolumns[n=3] \input tufte \stopcolumns \stopTwoThirds \stoptext ``` Instead of doing what I described, it made the contents of that inner column very narrow, but does not split it across columns. The \column command seems to have no effect. Thank you for your help, Walter

lmtx
by Hans Hagen 05 Aug '19

05 Aug '19

Hi, As we're progressing with the lmtx project (aka luametatex + context) the codebase gets adapted a bit. There are a few things that you need to keep an eye on: - As we test with lua 5.4 it can be that you need to wipe the cache after an update due to differences in byte code. This is only needed when you run into issues. At some point there might be a split in lua code (for luatex and luametatex) as 5.2 (luajittex, not evolving), 5.3 (luatex, stable frozen) and 5.4 (luametatex, experimental progressing) have a couple of different properties that we might want to benefit from. - The code base gets split in "Mark Four" and "Mark Fourty" files. Some of these are permanent, some can be temporary. It can for instance relate to features in and experiments with the engine. The only convenient way to test things is in 'real situations' and often issues can be solved fast. - As we're experimenting with metafun (and luagraph and ...) we also explore new interfaces. This results in a different codebase but should go unnoticed for existing code. Of course metafun 2.0 (hip and modern internet version speak) can bring interesting new things in the end. As usual, happy testing.

Captions with background
by Henning Hraban Ramm 04 Aug '19

04 Aug '19

Hi, in my books I typeset captions onto full page images, therefore I need a background; in the attached example it’s just a white box, usually I use a MetaPost shadow (some of you helped me with that a few years ago, current code see https://wiki.contextgarden.net/Drop_shadows) Now, the background should just enclose the text, not more. Since I don’t know how long the caption will be (I use the whole setup in a macro), I need a \vbox within \setlayer, but that always uses the full \textwidth, regardless of width settings of \framed. If the caption is short, the box should be minimal. Is this possible? Even better would be a textbackground just behind the text lines. Unfortunately my MP foo is not up to the task, the rectangular shadow was hard enough, but I’d try. There’s an example in details.pdf, but I don’t understand how I could manipulate the path around the text (not: paragraph). The example shows another problem: If you run it with --mode=arrange, the bleed is cut off. Is this a matter of settings or a bug? Greetlings, Hraban

\setupheadertexts \setupfootertexts
by Alan Braslau 03 Aug '19

03 Aug '19

Hello, \setupheadertexts [{center}] sets a centered header (and wipes-out any left and right header) \setupheadertexts [{left}] [{right}] sets the left and right headers (and keeps the centered header) \setupheadertexts [{left odd}] [{right odd}] [{left even}] [{right even}] sets the left and right headers for even and odd pages (perhaps I have this backwards?) (1) It would be useful to have \setupheadertexts [{left}] [{center}] [{right}] but this does not work. In this case, we probably also need a *six* argument version (even/odd). (2) It would also be useful that \setupheadertexts [{center}] NOT wipe-out left and right if they are set (but I could live with this perhaps historical behavior if we were to have (1).) (3) It is a bit messy that one must use \setupheader [] \setupheader [left] [right] *two calls* in order to have no centered header. (Again, I could live with \setupheader [left] [] [right] if we were to have (1).) Similarly for footertexts, of course. What is the reasoning, presently? ALTERNATIVELY (or additionally), we could have \setupheadertexts [center={center}, left={left}, lefteven={left, even}, ...] which would be even cleaner. Thanks, Alan

about SimpleSlides

Hi all, SimpleSlides is very useful for novice users so I do use it. But I encountered few problems which, I'm afraid, might be known. When we use a style BigNumber (or Embossed), an error occured: --------- tex error > tex error on line 87 in file /usr/share/texmf/tex/context/third/simpleslides/s-simpleslides-BigNumber.tex: ! Undefined control sequence l.87 \beginOLDTEX --------- I modified s-simpleslides-BigNumber.tex as follows: comment out from line #87 to #99 % \beginOLDTEX ... % \endLUATEX except line #98 \definefontsynonym [BigNumberFont] [name:texgyreherosbold] then it seems to work fine. But I suspect unconditional definition is not good so I'd like to know the correct fix. Another problem is with style Split. Browsing simpleslides.pdf, I think date, author, title and page number should be displayed on each slide but, in fact, we can't see them except page number. It seems, e.g. the following in s-simpleslides-Split.tex fails to get the "date". draw \sometxt[simpleslides:sometxt:left]{\getvariable{simpleslides:title}{date}} I think it is very helpful to see date, title on a slide so I'd like to know the fix. Thanks in advance. Best regards, Atsuhito Kohda

Figure labels in combinations
by Luca Mauri 30 Jul '19

30 Jul '19

I am trying to typeset two or more figures next to each other, inside a floating environment, each with its own label. I am familiar with a mechanism of the form \startplacefigure[reference=pic] \startcombination[3*1] {figure 1}{a} {figure 2}{b} {figure 3}{c} \stopcombination \stopplacefigure which then requires \in{figure}{b}[pic] to reference, as documented on the context wiki. The problem with this mechanism is that if figure 2, say, is moved elsewhere and ts label becomes "d", all references to it have to be corrected by hand. Is there a mechanism to reference directly the figures inside, without having to depend on the outer float? What I am thinking of, is an hypothetical "\placeinlinefigure" command, so that one could write, in analogy with \placefigure, \startplacefigure[number=no] \startcombination[3*1] {\placeinlinefigure[pic1]{figure 1}}{} {\placeinlinefigure[pic2]{figure 2}}{} {\placeinlinefigure[pic3]{figure 3}}{} \stopcombination \stopplacefigure so that one could then use \in[pic1] Of course, there is then the issue of having the ability to use the same counter of the placefigure environment, and of disabling the combination caption. I could not find anything along these lines in the documentation; also tried to concoct a "nonfloating" float or to use an enumeration, but was not able to come up with a solution. Luca

In a two column layout, activate line numbering for one column only
by Oliver von Criegern 30 Jul '19

30 Jul '19

Dear list members, I am trying to recreate a layout for some dictionary with ConTeXt. It is a two column layout with line numbering between the columns, that is, there is only one numbering for both columns. How can I do this with ConTeXt? I would need either an option to activate line numbering only for one column, which, as far as I can see, does not exist; or I could use the "command" option for "\setuplinenumbering" to make the line numbers dissappear for one column, but then I would need some way to decide whether a line number belongs to the first or to the second column, some command that returns to me the number of the actual column, which I can't find, too. For illustration, I give a minimal example: ||\setuppapersize[A4][A4]\setupbodyfont[9pt]|| |||\setupcolumns[n=2, distance=1cm, ]\setuplinenumbering[step=5, method=page, location=right, align=flushright, width=.25cm]\starttext\startcolumns\startlinenumbering\dorecurse{10}{\inputlorem}\par\stoplinenumbering\stopcolumns\stoptext||| In the result, there are (as is to be expected) line numbers between both columns and also to the right of the second column. How can I get rid of the latter ones? (For the pdf result see also: https://tex.stackexchange.com/questions/501269/context-how-to-have-line-num…) Best regards, Oliver. ||

consecutive full stops in "num" bib style after "et al"
by Sanjoy Mahajan 30 Jul '19

30 Jul '19

In the "num" bibliography style, bibliography entries that get "et al."ed (the author list is too long and "et al." is inserted) end up with two full stops in a row. Here's a minimal example: \setupbibtex[database=tmp] \setuppublications[alternative=num] \setuppublicationlist[artauthoretallimit=3, authoretaldisplay=3, editoretaldisplay=3, artauthoretaldisplay=3, % authoretaltext={ et al}, % artauthoretaltext={ et al}, ] \starttext Test \cite[Larkin:1980]. \blank[big] \placepublications[criterium=text] \stoptext (The tmp.bib file is attached.) The bibliography entry is: [1] Jill Larkin, John McDermott and Dorothea P. Simon et al.. Expert and novice performance in solving physics problems. Science, 208(4450):1335--1342, 1980. The doubled full stop can be fixed by commenting in the two lines % authoretaltext={ et al}, % artauthoretaltext={ et al}, Should these commented-in settings be the default for the "num" style (because it'll always put one more full stop between the author list and the title)? Another workaround is never to use et al. But that idea failed when I had to cite the Nobel-Prize-winning gravity-wave paper ("Observation of Gravitational Waves from a Binary Black Hole Merger"). It has, I think, 1000 authors! -- -Sanjoy <http://savelongwharfpark.org/> Save Long Wharf Park in Boston Harbor! <http://streetfightingmath.com/> Six reasoning tools to make hard problems easy.

It seems, e.g. the following in s-simpleslides-Split.tex fails to get the "date". draw \sometxt[simpleslides:sometxt:left]{\getvariable{simpleslides:title}{date}} I think it is very helpful to see date, title on a slide so I'd like to know the fix. Thanks in advance. Best regards, Atsuhito Kohda

In this newsletter: * 2018 journal progress * 2017 journal articles * ConTeXt Meeting 2019 updates * Board elections * Becoming a CG member * Membership promo action = 2018 journal progress = Our next ConTeXt Group journal issue is finished! It will go off to the printer today, with expected delivery to our members at or around the next meeting in September. The Table of Contents is already online at: https://articles.contextgarden.net/journal/2018.html The PDFs are not yet publicly available but current CG Members can send me an email for an advance copy of any of the article PDFs. If you are not a member, you will have to wait until summer 2020. = 2017 journal articles = Also on the articles site: we enabled the pdf downloads for the articles in the 2017 journal: https://articles.contextgarden.net/journal/2017.html = ConTeXt Meeting 2019 updates = Hans plans to do a number of announcements about the future of ConTeXt, LuaTeX and MetaPost (LMTX) which should be exciting you as well! If you have not registered yet, please consider joining us at ’t Sjetootje, Bassenge-Boirs, Belgium on September 16–21, 2019. Some other ‘surprise' talks have been added to the abstracts page, and submissions are still welcome as there is still some room in the program. (not that free time cannot be filled with Hans talking, but we have to consider the health condition of his throat.) The ConTeXt meeting is an excellent way to get help with any problems you may have in ConTeXt, to learn about future directions of ConTeXt and LuaTeX, or just to talk and have a drink with other ConTeXt users. You do not have to be a ConTeXt Group member to attend the meeting, but members do get a meeting fees discount worth more than the CG membership fees for a year. In fact, if you attend for the very first time, there is an extra discount for that as well. For registration and other information, see the website at https://meeting.contextgarden.net/2019 The 13th ConTeXt Meeting is sponsored by Dante e.V (www.dante.de) and NTG (www.ntg.nl) as well as by Pragma ADE (Hans & Ton) and Bittext (Taco). We are very grateful to all our sponsors! = Board elections = The ConTeXt meeting is also the location of the annual CG membership meeting. This year, no less than four board members are forced to resign according to the bylaws. We are looking for CG members to help fill those spots in the board. If you are interested in joining the CG board, please send a message to any of the current board members and we will get in touch with you. We can really use the help! Our previous newsletter already provided one tentative new board member, but ideally we would like at least one more candidate. = Becoming a CG member = Our official stated purpose: * to promote the ConTeXt typographic system; * provide its users with infrastructure and information; * support its development; * provide a platform for discussion of quality automated typography; * serve as a meeting place for people who want the best possible typography for the languages and writings of the world; * organise congresses and trainings for users and ConTeXt developers to meet; * provide financial support to those involved in documentation and ConTeXt development, including through their participation in conferences; * produce and sell printed materials on ConTeXt; * sell advertising items for ConTeXt. The more members we have, the more we can do. If you are not a member already, please consider registering at https://group.contextgarden.net/register.shtml Membership fees are €40 per year for normal members, €20 for students, and €200 for institutions and corporations. = Membership promo action = Our 50th active member is David Neubauer, and he will get his fees for 2018-2019 waived.

Override MathML formula label
by Duncan Hothersall 29 Jul '19

29 Jul '19

Hi all. In processing MathML if I want a formula to be numbered I add a label="X" attribute to the <formula> tag as per: \usemodule[mathml] \starttext \xmlprocessdata{}{<formula label='X'> <math xmlns='http://www.w3.org/1998/Math/MathML'> <mi>p</mi><mo>=</mo><mi>c</mi><mo>-</mo><mi>t</mi> </math> </formula>}{} \stoptext This will label the formula as (1). I know I can adjust how the automatic numbering is generated using \setupformulae, but how can I override the label used for a specific formula, say to set it to (36A)? Basically I have a setup where formulae are mostly numbered sequentially but occasionally individual formulae need to have an out-of-sequence or differently formatted number. Thanks as ever for any help. Duncan

grid+formulas: bug or expected behavior?
by Luca Donetti 26 Jul '19

26 Jul '19

Dear all, I'm typesetting a document with grid layout and some formulas, like in the minimal example below: %%%%%%%%%%%%%%%%%%%%%%%%%%%% \setuplayout[grid=yes] \showgrid \starttext \input knuth %\blank \startformula a = b + c \stopformula \input knuth \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%% I don't have any specific need for the alignment of the formula with respect to the grid, but I expect the text below the formula to be on the grid. However, I've not been able to achieve that with any of the layout options described in the latest "details.pdf" manual: in all cases I've tried the text below the formula doesn't "sit" on the grid. While I do not understand this behavior, I've thought that it could be the intended one, because this is what happens in chapter 4 of the "details" manual. Then, I noticed that in older versions of the same manual (for example the one included in texlive 2017) the behavior shown in chapter 4 is the one I expect: the text after formulas is aligned to the grid. So I'm a bit puzzled: should the text after formulas be aligned to the grid or not? Is this a (known?) bug or intended behavior? If this is the expected behavior, I can live with that because by trial and error I found a workaround. If I employ a \blank command before the formula (as in the commented line in the above example), the text after the formula is "correctly" aligned. Thank you in advance. LD

If I write: \startlinecorrection \startformula a = b + c \stopformula \stoplinecorrection the text below the formula is correctly aligned to the grid. However, what puzzles me is that the version _without_ \startlinecorrection ... \stoplinecorrection works with an old version of context (from texlive 2017). Moreover, i guess this is not something due to my setup, because I observe the same (or at least very similar) behavior in the chapter of the details.pdf manual about grid and math. In the attached screenshot I show the first page of such chapter in the version shipped with a recent beta (on the left) and with texlive 2017 (on the right). While in the old version the text after the formulas is aligned to the grid, in the new version of the manual this is not the case: the text is not aligned. Is this a known (documented?) change or an unnoticed regression? Thank you in advance, LD

some mac fonts do not work correctly
by Ulrike Fischer 25 Jul '19

25 Jul '19

Hello Hans, we got a bug report that some (proprietary) mac fonts don't work correctly. The reason seem to be that the OpenType cmap format used by these fonts isn't supported by the fontloader. The necessary cmap formats are "platform 0 (Unicode), encoding 1 (Unicode 1.1(?)), format 12" and maybe as a fallback "platform 1 (Mac), encoding 0 (Roman), format 0". A test would be \starttext \font\oddfont="Big Caslon Medium" \oddfont A \stoptext (I don't have a mac and so couldn't check) The bug report we got is here https://github.com/u-fischer/luaotfload/issues/73 -- Ulrike Fischer https://www.troubleshooting-tex.de/

currently supported platforms
by Henning Hraban Ramm 24 Jul '19

24 Jul '19

Hi, I just checked the list of supported platforms in the wiki (https://wiki.contextgarden.net/ConTeXt_Standalone#Supported_platforms) and in the setup folder (http://minimals.contextgarden.net/setup/) there were several differences. I tried to update, this is now in the wiki: Supported platforms Platform Short name Notes Windows mswin from W32TeX Windows/CygWin cygwin Linux, 32-bit linux Debian 8 Linux, 64-bit linux-64 Debian 8 Linux, ARM (low end.) linux-arm Raspbian 8 Linux, musl linuxmusl-64 Alpine Mac OS X, Intel (64-bit) osx-64 Mac OS X 10.6 FreeBSD, 32-bit freebsd FreeBSD, 64-bit freebsd-amd64 OpenBSD 6.5, 32-bit openbsd6.5 OpenBSD 6.5, 64-bit openbsd6.5-amd64 Solaris, Intel solaris-intel Solaris 10 on OpenCSW Solaris, Sparc solaris-sparc Solaris 10 on OpenCSW I.e., I replaced OpenBSD 6.3 and 6.4 with 6.5 and added CygWin and Linux MUSL. Is "Alpine" correct for MUSL? There are additional versions win32 and win64 - what’s the difference to mswin? Are those also from W32TeX? In the wiki it says kfreebsd would be still supported via Debian - is this still true? BTW is there any chance to get "first-setup.sh --context=date" back?

\glueexpr in lmtx
by Marcel Fabian Krüger 23 Jul '19

23 Jul '19

Hi, I stumbled upon some odd behaviour of \glueexpr in lmtx. Take the following document: \starttext \the\glueexpr 0.0pt \relax \newskip\myskip \myskip=\glueexpr 0.0pt \relax \stoptext Without lmtx this works fine. Under lmtx, the *first* use of `\glueexpr`, after `\the`, works fine too. On the other hand, the other `\glueexpr`, after `\myskip=`, complains about a "Illegal unit of measure (pt inserted)". It does not seem to accept the fractional part, everything works again if I use \starttext \the\glueexpr 0.0pt \relax \newskip\myskip \myskip=\glueexpr 0pt \relax \stoptext Am I missing something here or is this a bug?

Re: [NTG-context] Place footnote after reference
by Huseyin Özoguz 23 Jul '19

23 Jul '19

Thank Taco, that worked in the example, of course the general problem stays (thanks to Rik Kabel, too). But with your suggestion I dicovered a interesting behaviour, see this example: \showgrid \setupnote[footnote][before=] \starttext \input tufte \input tufte \footnote{Footnote 1} \input tufte \input tufte \dorecurse{35}{Blub or what }\footnote{Footnote 2} That does\footnote{Footnote 3} only\footnote{Footnote 4} work in special cases. \stoptext Now Context indeed sets the third and fourth footnote on the second page, but leaves the reference to them on the last line of the first page. This is exactly the behaviour I want in general. Could we force that? /For testing: /If we add another footnote in the example above, it fails again - despite of the possibility to just typeset the lines exactly like in the example above, just move the footnotes on the next page, not the references - here might be some logic-mistake at work, because there should be no difference in my opinion between the examples: \showgrid \setupnote[footnote][before=] \starttext \input tufte \input tufte \footnote{Footnote 1} \input tufte \input tufte \footnote{Footnote extra} \dorecurse{35}{Blub or what }\footnote{Footnote 2} That does\footnote{Footnote 3} only\footnote{Footnote 4} work in special cases. \stoptext -- Huseyin Özoguz E-Mail: h.oezoguz(a)mmnetz.de

Hi, > But I admit that I do not understand the problem all that well. I have > never run into a situation where I want the footnote to explicitly > *not* appear with its reference (except in endnotes). If my grid > settings were that specific, I would be using endnotes anyway. I have this problem everywhere in a 400-page project with hundrets of footnotes and no special grid settings at all. How would you solve this situation (my minexamle): \showgrid \starttext \input tufte \input tufte \footnote{Footnote 1} \input tufte \input tufte \dorecurse{35}{Blub or what }\footnote{Footnote 2} \input tufte \stoptext The problem is, that Context (or Tex) skips lines, which is poor typesetting, too many even than necessary in some cases, and that is not suitable. Endnotes are no solutions aswell, I need footnotes. So the solution to have reference and footnote not on the same page seems the least bad workaround, if possible at all.

Place footnote after reference
by Huseyin Özoguz 22 Jul '19

22 Jul '19

Hello, ConText seems to try to place the footnote on the same page as the footenotereference. See this example: \showgrid \starttext \input tufte \input tufte \footnote{Footnote 1} \input tufte \input tufte \dorecurse{35}{Blub or what }\footnote{Footnote 2} \input tufte \stoptext But that results into one (or two?) fewer line on the first page. Is there a possibility to implement the following rule? -> NEVER move lines onto the next page to achieve footnote and reference beging on the same page. If necessary set the footnote on the next page, after the reference. Or would you suggest a better solution? I have a book with grid=yes, so the default-setting is not suitable. Thanks Huseyin -- Huseyin Özoguz E-Mail: h.oezoguz(a)mmnetz.de

Unwanted white box above float
by Duncan Hothersall 22 Jul '19

22 Jul '19

Hi all. Have been experimenting with the many and varied options for placefloat to try to resolve this problem with no success. As per minimal example below I have nearly what I'm after - an image which floats to the right of a background box with a 1em offset - but I can't get rid of the white box which appears above it no matter what permutations I try. (Secondary query: why do I have to set leftoffset=, rightoffset= etc. individually for the text background? offset= seems to have no effect.) Thanks for any help you can offer. \definetextbackground[TintBoxedBackground] [background=color, backgroundcolor=cyan, frame=off, leftoffset=1em, rightoffset=1em, topoffset=1em, bottomoffset=1em, location=paragraph] \definefloat[thematicimage][figure] \setupfloat[thematicimage] [default=right,none}, offset=1em, margin=0em, background=color, backgroundcolor=cyan, rightmargindistance=-1em] \starttext \starttextbackground[TintBoxedBackground] {\bf Lorem ipsum dolor sit amet}\blank \placethematicimage{}{\externalfigure[cow][width=0.30\makeupwidth]} Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

VORG and vmtx table in fontloader

22 Jul '19

Hello all, It seems that ConTeXt's fontloader (hence luaotfload's fontloader) skips to load the VORG table and topSideBearing in the vmtx table These informations are used to get the vertical origin of a glyph. > readers.vorg = function(f,fontdata,specification) > reportskippedtable(f,fontdata,"vorg",specification.glyphs) > end > readers.vmtx = function(f,fontdata,specification) > ... > for i=0,nofmetrics-1 do > ... > if vheight ~= 0 and vheight ~= vdefault then > glyph.vheight = vheight > end > -- if topsidebearing ~= 0 then > -- glyph.tsb = topsidebearing > -- end I don't know whether vertical metrics are used in ConTeXt. But, they will be useful for other packages (e.g., LuaTeX-ja) to improve vertical typesetting. Regards Hironori KITAGAWA <h_kitagawa2001(a)yahoo.co.jp>

footnotes in columns not working
by Charles Doherty 22 Jul '19

22 Jul '19

Dear Hans, I have been typesetting a Newsletter using ConTeXt since 2003. I have updated the programme regularly and made adjustments to my template as needed. Following the most recent update I have problems with footnotes in columns. Depending on the number and length of the footnotes I have varied between placing them at the end of each column or as a list at the end of each page using: \setupnote[footnote][location=columns] or commenting out %\setupnote[footnote][location=columns] to get what I need. In the attached image I had commented out %\setupnote[footnote][location=columns] expecting to get footnotes arranged one beneath the other at the bottom of the page but I get them in two columns and both run off the page. Can you help on this? I attach an .png of the result. Thanks, Charlie

font switching commands
by Atsuhito Kohda 22 Jul '19

22 Jul '19

Hi all "Manuals-ConTeXt wiki" provides us very important and useful information and we find cont-eni.pdf in "overview". In the manual, font switching commands \vi, \vii, \viii, \ix, \x, \xi, \xii are explained in p.113 but it seems they don't work except \vi and \xi. >From my simple test with ConTeXt, \xi produces a greek letter "ξ" as in traditional TeX and \vi seems to do nothing. Is the above explanation obsolete or is additional setup necessary? I'd like to know what is the real situation of these commands. Thanks in advance. Best regards, Atsuhito Kohda

Quotation marks
by Dmitry Starostin 21 Jul '19

21 Jul '19

I understand it might have been deliberately and for various reasons, but ConTeXt has no analogue for {``} and {''} for quotes. \quotation is a replacement, but it is awkward if you write a draft in ConTeXt and make the final variant in pdfLatex. Is there a ready solution for the quotation marks as marked out in the text? Or one needs to write his own macro for this?

Side figure bug in mkiv?

Using \currentreferencenumber triggers “has a hidden number” in log file
by Marco Patzer 18 Jul '19

18 Jul '19

Hi, I use \enabletrackers [structures.referencing.empty] to catch references by number to sections without a number. The log file contains “has a hidden number…” in that case. I have a command that uses \currentreferencenumber which triggers the “has a hidden number…” warning in the log file. But that command takes care not to output the contents of that variable. But merely using it in an \doif\currentreferencenumber is sufficient to trigger the log message. Example: \enabletrackers [structures.referencing.empty] \def\foo[#1]{%% \doifreferencefoundelse{#1}{%% \doifelse\currentreferencenumber\emptyreference {Foo}{Bar}}%% } \setuphead [section] [number=no] \starttext \startsection [title=Foo, reference=sec:foo] \samplefile{knuth} \stopsection \foo[sec:foo] \stoptext Then check the log file for “has a hidden number”. 1) How to not trigger the log message when checking \currentreferencenumber? Or alternatively 2) Is there a better way to find invisible references? Marco

For example, consider this recent question on TeX.SE: https://tex.stackexchange.com/questions/499464/context-empty-line-in-enumer… which basically boils down to the difference between: \showboxes \starttext \noindent \inmargin{Example 1} \startitemize \item This is how enumeration works. \stopitemize \inmargin{Example 2} \startitemize \item This works correctly \stopitemize \stoptext Note that the first example has an extra space before the itemize. In principle, replacing \noindent by \noindentation fixes the extra line break, but it does not work with enumerations because it uses \inmargin[scope=local]: \showboxes \starttext \noindentation \inmargin[scope=local]{Example 1} \startitemize \item This is how enumeration works. \stopitemize \inmargin[scope=local]{Example 2} \startitemize \item This works correctly \stopitemize \stoptext where the box containing "noindentation" is misgligned. So, two questions: * Why is \noindent used instead of \noidentation? * Is there a bug with scope=local? Aditya

reference containing parentheses causes trouble
by Sanjoy Mahajan 12 Jul '19

12 Jul '19

Dear List, Warning: The following may be a bug or feature or just my misunderstanding! It seems that parentheses cause trouble in references. MNWE: \starttext \section[sec:one(two)]{One} As you see in sec.~\in[sec:one(two)], \stoptext The "in sec.~\in[sec:one(two)]" typesets as "in sec. ??" and the log shows: references > start missing references references > 1 [][sec:one(two)] references > stop missing references (It all works fine upon deleting "(two)" throughout.) Is this behavior known and expected? If it is, I'll add a note to the "References" page on the wiki. -Sanjoy

registers: subentry indentation different from word--number gap?
by Sanjoy Mahajan 12 Jul '19

12 Jul '19

I don't think the current behavior is a bug, so the following is a feature request: With the following fairly minimal example \setupregister[index][indicator=no, distance=0.5em] \starttext ABC\index{x}DEF\index{x+yyz} \blank \placeindex \stoptext the distance parameter sets (1) the hanging indentation of the 'yyz' subentry and also (2) the distance between an entry and its pagenumber. (That's what a look at strc-reg.mkiv shows too.) It's a matter of taste, but my eye thinks that 0.5em is right for no. 2, but too small for no. 1 -- whereas the default (1em) is just right for no. 1 but too large for no. 2. Thus, could the two dimensions be decoupled and bcome settable indepently? Perhaps keep 'distance' for the entry--pagenumber distance (no. 2), which is its meaning on the wiki, and invent 'subdistance' for the hanging indent (no. 1)? I've just realized a cheap hack to do the same, so maybe it's not worth messing with backward compatability by adding a new parameter. The hack: \def\blah#1{#1\hskip-0.5em} \setupregister[index][indicator=no, distance=1em, textcommand=\blah] -- -Sanjoy <http://savelongwharfpark.org/> Save Long Wharf Park in Boston Harbor! <http://streetfightingmath.com/> Six reasoning tools to make hard problems easy.

Split extreme tables across tables
by Thangalin 11 Jul '19

11 Jul '19

The following document does not split across tables, which is a little surprising: \starttext \startplacetable[title={Average Annual Temperatures}] \startxtable \startxtablehead[head] \startxrow \startxcell[align=middle,width={0.10\textwidth}] Year \stopxcell \startxcell[align=middle,width={0.14\textwidth}] Value \stopxcell \stopxrow \stopxtablehead \startxtablebody[body] \dorecurse{100}{% \startxrow \startxcell[align=middle,width={0.10\textwidth}] 1880 \stopxcell \startxcell[align=middle,width={0.14\textwidth}] 0.1146 \stopxcell \stopxrow} \stopxtablebody \startxtablefoot[foot] \startxrow \startxcell[align=middle,width={0.10\textwidth}] 2018 \stopxcell \startxcell[align=middle,width={0.14\textwidth}] 1.014 \stopxcell \stopxrow \stopxtablefoot \stopxtable \stopplacetable \stoptext I'd have thought the default behaviour would be to split because the alternative is for the table content to scroll into the footer and off the page. A fix is to use: \startplacetable[title={Average Annual Temperatures}, location={split}] However, when the document is generated using pandoc, injecting location={split} is not feasible. It would be convenient if there was a way to use setups to override the location option for \startplacetable. Henri Menke provided a work around: let\oldstartplacetable\startplacetable \unexpanded\def\startplacetable{\dosingleempty\newstartplacetable} \def\newstartplacetable[#1]{\oldstartplacetable[#1,location={split}]} See: https://tex.stackexchange.com/a/499453/2148 This does the job, but it doesn't feel like the ConTeXt way. How would you use setups to enable page splitting on extreme tables? Thank you!

an object representation of the node list of a paragraph: a lua table or a JSON
by mf 10 Jul '19

10 Jul '19

Hello list, i'd like having an object representation of a typeset paragraph or even a page, preferably as a JSON object, but a Lua table is equally good. My reference is section "4.4 Node lists" of the CLD manual. Before writing an iterator over the list of nodes of a paragraph, figuring out all the possible nodes and their fields, i'm wondering if there's some hidden tool in the ConTeXt coffer to simplify the task.

index page ranges where start page == end page
by Sanjoy Mahajan 10 Jul '19

10 Jul '19

The following probably well known minimal example \starttext \startregister[index][key1]{an entry}\input knuth\stopregister[index][key1] \placeindex \stoptext produces the index entry "an entry 1--1", where the page range should be just a single page. A question (and then two workarounds): Could ConTeXt automatically change such page ranges to the single page ("an entry 1")? Meanwhile, a couple of workarounds: In the MkII (pre-lua) days, I wrote a shell/sed/awk/perl script that converted the .pdf file to text, grepped for (strings that are likely to be) page ranges, and spat out lines where the page range should be a page. (Those days were so long ago that I've forgotten the script's language.) Then I would manually find and change the corresponding \startregister[index] in the source to a plain \index (and delete the corresponding \stopregister). In these MkIV days, with the index data in a lua table, I've been playing with the following python2 script that parse the .tuc file to spit out the same information slightly more reliably. In the next step, coming soon, the script will check that each \seeindex entry points to an actual entry and also that each \seeindex{also ...} entry originates from an actual entry (otherwise it shouldn't be "also"). The script requires the slpp package; pip install git+https://github.com/SirAnthony/slpp The parser in the script has a bug in that it doesn't handle minus signs in the lua table, maybe everywhere or maybe only some of them, so the script replaces them with "_" before sending the data to the parser (a terrible hack). To run the script: python check-index.py < file.tuc Here is check-index.py: # parse lua-format index-entry table extracted from book.tuc to check # that each xref points to an actual entry, and that, further, "see # also" src entries have at least one page ref (perhaps in subtree) # due to bug in slpp parser: replace "-" (minus signs) in data with "_" from slpp import slpp as lua from sys import stdin,stderr import re def tuclist2entry(l): return '+'.join(l) data = [] intro_re = r'utilitydata.structures.registers.collected\s*=' in_register_data = False for l in stdin: if re.match(intro_re, l): in_register_data = True data.append(re.sub(intro_re,'',l)) elif in_register_data: data.append(l) if re.match(r'}$', l): in_register_data = False data = re.sub("-", "_", ''.join(data)) dict = lua.decode(data) index = dict['index'] entries = [] xrefs = [] for entry in index['entries']: src = [x[0] for x in entry['list']] refs = entry['references'] if 'seeword' in entry: dest = entry['seeword']['text'] xrefs.append((src,dest)) else: page = refs['realpage'] if refs.get('lastrealpage',None) == page: print "silly range:", tuclist2entry(src) entries.append(src) for xref in xrefs: print tuclist2entry(xref[0]),'->', xref[1]

Is it possible to define a float environment that uses 2 captions? (and another question)
by Andres Conrado Montoya 09 Jul '19

09 Jul '19

I'm working on a book that uses tables and figures, but the editors want to use to diffferent captions for each figure: one as usual, with the float description and number, and another one with a "Source" for said float. Something like: --------------------------------- | | | Float | | | --------------------------------- Figure 1: The float description. Source: The float source. I know i can do it by hand, inserting line breaks in the caption and so on. But I was wondering if there is a programmatic way to do it, so I can, for example, change the "Caption" position to be above the float, but have the "Source" below it. LIke: Figure 1: The float description. --------------------------------- | | | Float | | | --------------------------------- Source: The float source. I've been reviewing the Wiki, but so far I have no idea how to approach it. Any recommendation will be very appreciated. Thank you for your time.

Re: [NTG-context] Typesetting Markdown – Part 5: Interpolation
by Andres Conrado 09 Jul '19

09 Jul '19

Thank you. I still don't really understand why can't you have a "presentational" yaml file and a "content" yaml file (I do it like that... I have a "variables.yaml" file for content and a "settings.yaml" file for presentational stuff, and use a "template.context" file with all my mapped variables within the ConTeXt code, and compile everything using pandoc). But I guess you want to do it this way. Or maybe I'm not really understanding your process. It's quite interesting in any case, and I'm learning a lot. Thanks for sharing.

interfaces.definecommand fails with brackets inside string arguments
by mf 09 Jul '19

09 Jul '19

Hello list, i've played a bit with interfaces.definecommand, that lets you define TeX macros from lua (see the "ConTeXt Lua Documents", 7.3 User interfacing). I found that the commands defined by interfaces.definecommand fail when you pass string arguments that contain brackets. I think cldf-int.lua needs a patch to support those kind of arguments. In the meantime it's possible to bypass the problem passing arguments with brackets inside double braces, as in the MWE attached. Best wishes, Massimiliano

From mkii to mkiv: MathML mtable alignment

problems with images, layers and crop marks
by Henning Hraban Ramm 08 Jul '19

08 Jul '19

Hi all, I’m quite quiet at the moment, because I can access my mailing list address only via inconvenient webmail; since I updated MacOS, neither Apple Mail nor Thunderbird will take my password anymore... :-(( Besides, I’m currently well paid for working with LaTeX, and my other projects get less time. Anyway, one of our authors finally submitted her final corrections, and "of course" my ConTeXt setup that still worked well in May doesn’t behave any more: * stacked layers won’t work on the first page (there should be a title bar above an image; it works on the back cover, but not on the front; but I can enable one of both layers) That might be related to: * on some right pages, including p.1 (cover), crop marks are shifted one page width to the right. * on some pages, crop marks are shifted vertically; might be related to using \offset for image placement. I’m trying to cook up MWEs, but the behaviour is so strange and irregular, that I don’t know if I can reproduce it in a simpler environment... I suspect my combined use of postponing, makeups, layers and \offset might have grown side effects since May. Any ideas?

crappy names in the fontloader
by Marcel Fabian Krüger 08 Jul '19

08 Jul '19

Hi everyone, under default settings, the fontloaders discards all glyph names which are considered "crappy", meaning matching the "p_crappyname" pattern in "font-oup.lua". For some names this makes a lot of sense. For example the name "uni0303" is considered "crappy" and it really provides no useful information. Then there are other names like "t_uni0303" which are still considered "crappy" while they actually aren't completely useless. So I think there would be some value in preserving them. Of course, you can always enable "otf.keepnames" if you need names like this. But I actually want to talk about another class of names: Look at "Udotbelow". This is IMHO a perfectly normal and useful name, but the fontloader still considers it "crappy" because it starts with a "U" followed by a letter which could be a hexadecimal number. I think this is a bit over-agressive. Maybe the "p_crappyname" pattern could be changed to only look for "u<hexadecimal>" if followed by "p_done", marking the end of a component? Best regards, Marcel Krüger

request for \definefontfamily and \definefallbackfamily
by Pablo Rodriguez 07 Jul '19

07 Jul '19

Hi Wolfgang, I have two requests to be implemented in \definefontfamily. The first one is that is able to load fonts not defined as entries in the font database. Here you have a minimal sample: \definefont[Test][file:texgyrepagella-regular.otf at 10pt] \definefont[TestOne][file:texgyrepagella-regular-500.otf at 10pt] \definefontfamily [mainface] [rm] [Pagella] [tf={file:texgyrepagella-regular.otf}, bf={file:texgyrepagella-regular-500.otf}] \setupbodyfont[mainface] \starttext normal\\ \bf bold not working\\ \Test this works \TestOne this works \stoptext The second one would be to allow method=uppercase to \definefallbackfamily, so it could be used to fake small caps (such as in https://mailman.ntg.nl/pipermail/ntg-context/2018/092878.html.

feature request
by Atsuhito Kohda 06 Jul '19

06 Jul '19

I've used LaTeX quite a long time but recently I begin to use ConTeXt too. So I'm very sorry if the following is well-known issue. I find an example of \pmatrix in p.21 of "ConTeXt Mark IV an excursion" (ma-cb-en.pdf). And I notice it is defined in /usr/share/texmf/tex/context/base/mkiv/math-pln.mkiv (in Debian). But it seems \bmatrix, \vmatrix are not defined yet. Is there any reason why they are not defined? Similar commands or environments \begin{bmatrix}...\end{bmatrix}, \begin{vmatrix}...\end{vmatrix} are very often used in mathematical LaTeX documents. It is very useful if we can use \bmatrix and \vmatrix in ConTeXt documents, so please add \unexpanded\def\bmatrix#1% {\left[\matrix{#1}\right]} \unexpanded\def\vmatrix#1% {\left|\matrix{#1}\right|} in math-pln.mkiv or somewhere. By the way, I think it is critical to set \setupmathematics[ampersand=normal] to use \matrix above but I can't find this setting in ma-cb-en.pdf It is great if this is added in ma-cb-en.pdf

I (metapost) can't handle numbers bigger than 32767.99998
by Zhichu 05 Jul '19

05 Jul '19

Hi everyone, I was using metapost to generate some symbols, as in "tex/texmf-context/metapost/context/fonts/mpiv/demo-symbols.tex" Occasionally, I want to customize a glyph whose charcode is a little large, say the character "院": ======================================== ~~~IPython In [1]: for c in u'院': print(ord(c)) 38498 ======================================== so I wrote: ======================================== beginglyph(38498,2,4,0) ; % high voltage interim ahlength := 1 ; drawarrow (1,4) -- (0,2) -- (2,3) -- (1,0) withcolor darkred ; endglyph ; ======================================== and I got: ======================================== ! Enormous number has been reduced. l.60 beginzhglyph(38498 ); I can't handle numbers bigger than 32767.99998; so I've changed your constant to that maximum amount. ======================================== So charcode is a 15-bit integer? Currently, I use `beginglyph(32767,2,4,0) ;` and call it with \char"7FFF. Not an elegant way I think. Is there a fix? I checked the metapost manual and found that charcode is only used to set the filename to something like %{jobname}.%{charcode} I can't see why there's a limit for charcode.

mapping seeregister command to xml

Hi, I'm having trouble mapping the seeregister command to an xml setup. Example (looks somewhat messy, but explains why I need it): \startbuffer[test] <document> <p>This is a test. <emph>IGRR</emph> 4, 988<seeinscription sort="IGRR4+988" target="TAM 2 677"><emph>IGRR</emph> 4+988</seeinscription> = <emph>TAM</emph> 2, 677<inscription sort="TAM2+677"><emph>TAM</emph> 2+677</inscription></p> </document> \stopbuffer \startxmlsetups xml:testsetups \xmlsetsetup{#1}{*}{-} \xmlsetsetup{#1}{document|p|inscription|seeinscription|emph|index}{xml:*} \stopxmlsetups \xmlregistersetup{xml:testsetups} \startxmlsetups xml:document \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1} \par \stopxmlsetups \startxmlsetups xml:emph {\em \xmlflush{#1}} \stopxmlsetups \startxmlsetups xml:inscription \expanded{\inscription[\xmlatt{#1}{sort}]{\xmlflush{#1}}} \stopxmlsetups \startxmlsetups xml:seeinscription \expanded{\seeinscription[\xmlatt{#1}{sort}]{\xmlflush{#1}}{\xmlatt{#1}{target}}} \stopxmlsetups \defineregister[inscription][inscriptions] \setupregister[inscription][pagestyle=, textstyle=, location=right, prefix=none, indicator=no] \starttext \xmlprocessbuffer{main}{test}{} \blank [line] \placeregister[inscription] \stoptext Maybe my problem is with expansion in index entries? I must admit that I haven't really grasped why the \expanded was necessary and what it does... All best Thomas

Dear sirs, Is there a way to make crosswords or word puzzles in context? In my hippocampus I have a vague idea that this has already been tried, but I can't find this code anymore. Have a great day Jorge

Why is the list so quiet these days?

Is there an event or something else? Or everybody is just busy?

mkiv MathML bug?
by Duncan Hothersall 27 Jun '19

27 Jun '19

I'm not sure this is something more general in the MathML module or if it's specific to the vertical bar in this particular context, but here is a minimal example showing that the "=0" at the end of the equation is disappearing: \usemodule[mathml] \starttext \xmlprocessdata{}{<imath> <math xmlns='http://www.w3.org/1998/Math/MathML'> <mi>A</mi> <mfenced open="(" close=")" separators=""> <mi>B</mi> <mo>|</mo> <mi>C</mi> </mfenced> <mo>=</mo> <mn>0</mn> </math> </imath>}{} \stoptext And here is a workaround using <mtext> instead of <mo> for the vertical bar which makes the "=0" magically reappear again: \usemodule[mathml] \starttext \xmlprocessdata{}{<imath> <math xmlns='http://www.w3.org/1998/Math/MathML'> <mi>A</mi> <mfenced open="(" close=")" separators=""> <mi>B</mi> <mtext>|</mtext> <mi>C</mi> </mfenced> <mo>=</mo> <mn>0</mn> </math> </imath>}{} \stoptext Flagged up mainly in case it is a bigger problem than just vertical bars in this specific context. Thanks, Duncan

Strange behavior in somewhat complex layout
by Andres Conrado Montoya 27 Jun '19

27 Jun '19

Hello list, I'm trying to make something using bits and examples found here and elsewhere, but I'm hitting a wall. I know there's a flawed logic in my approach, but I can't figure it out. Any help is appreciated. Expected behavior of the following MWE: When starting a new chapter, check if the page is even (left page), if so, fill it with color, and start the chapter in the next odd page (right page), removing the header but leaving the footer in that start-chapter page; and if this is a start-chapter page, use a specific graphic overlay for the page, but if if not (if its a regular page), use another graphic. Result: The header still appears in the start-chapter page, if it comes after the color filled page. But, if the start-chapter page comes after a regular (even) page, everything works as expected (no color-filled page, no header in the start-chapter page). MWE: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% START MWE \definecolor[rojo][h=ED553B] \definehighlight[rojo][color=rojo] \startMPinclusions numeric u ; u := 1.125pt ; numeric i ; i := 0.125in ; string prevChapterTitle, currentChapterTitle; prevChapterTitle := ""; currentChapterTitle := ""; \stopMPinclusions \startuseMPgraphic{page:background} StartPage; currentChapterTitle := "\namedstructurevariable{chapter}{title}"; if currentChapterTitle <> prevChapterTitle : fill (topboundary Page -- cycle) enlarged(0,8i) shifted (0,-4i) withcolor transparent(4, 0.2, \MPcolor{rojo}) ; fill (bottomboundary Page -- cycle) enlarged(0,1u) shifted (0,6i) withcolor \MPcolor{rojo} ; prevChapterTitle := currentChapterTitle ; else: fill (topboundary Page -- cycle) enlarged(0,0.25u) shifted (0,-7i+3u) withcolor \MPcolor{rojo} ; fill (bottomboundary Page -- cycle) enlarged(0,0.25u) shifted (0,6i) withcolor \MPcolor{rojo} ; fi; StopPage; \stopuseMPgraphic \defineoverlay [chapter:background] [\useMPgraphic{page:background}] \setupbackgrounds[page][background=chapter:background] \definepagebreak[firstpagebreak][yes,header] \startsetups [chapter:before] \doifoddpageelse {} {\pushbackground[page] \setupbackgrounds[page][background=color,backgroundcolor=rojo] \page[yes,right] \popbackground} \stopsetups \setuphead[chapter] [width=20em, before=\directsetup{chapter:before}, align={flushleft,nothyphenated,verytolerant}, style={\tfd\sansbold}, header=empty, page=yes, commandbefore={\blank[1.75in]}, after={\blackrule[color=rojo,height=4pt,width=6em]\blank[1.25in]}] \setuppagenumbering[alternative=doublesided,location=] \setupheadertexts [] [{{\small\sans\getmarking[chapter]}}] [{{\small\sans\getmarking[chapter]}}] [] \setupfootertexts [] [{\rojo{\small\sansbold\pagenumber}}] [{\rojo{\small\sansbold\pagenumber}}] [] \starttext \dorecurse{4}{% \startchapter[title={A chapter with a really long, long title}] \dorecurse{9}{\input{tufte}} \stopchapter \startchapter[title={A different chapter with a really long, long title}] \dorecurse{6}{\input{tufte}} \stopchapter} \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% STOP MWE Thank you for your time.
