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

lmtx: img?
by Henning Hraban Ramm 03 Aug '19

Hi, when I try to compile my books with lmtx, it chokes on my Lua image library. Seems like "img" (esp. img.scan) is gone. Is there a replacement? Greetlings, Hraban --- https://www.fiee.net http://wiki.contextgarden.net https://www.dreiviertelhaus.de GPG Key ID 1C9B22FD

\setupheadertexts \setupfootertexts
by Alan Braslau 02 Aug '19

02 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

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

(again) inmargin attachments in notes
by Pablo Rodriguez 30 Jul '19

30 Jul '19

Hi Hans, I have the following sample: \showframe\showgrid \setupinteraction[state=start] \setupinteractionscreen[option=attachment] \setupattachment[location=inmargin] \starttext a\attachment[file=xml-mkiv.pdf] b\footnote{\attachment[file=i-context.pdf]} \stoptext Inmargin attachment from notes aren’t shown in Acrobat nor displayed in margin. Files are embedded. I have a bunch of documents (over 100) in which I have to embed other PDF documents and I need them to be in the marginal space from notes. Sorry for reporting this again (https://mailman.ntg.nl/pipermail/ntg-context/2019/094337.html) but this issue is relevant for me. Many thanks for your help, Pablo -- http://www.ousia.tk

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.
