The graph is not visible.

Hi, I don't know if I can explain the problem I'm having. I made a project with 14 chapters. In each of them, there are graphics embedding metapost code. I proceed as follows : I compile each chapter alone with lmtx then I compile the project containing the 14 chapters. I didn't encounter any problems except with a graphic from the last chapter. It is indeed in chapter 14 but not in the project ! I give the code for this graph. Thanks.

start/stopregister

Hi all, has \startregister been superseded in luametatex or is it not yet implemented? I tried to read strc-reg.lmt but couldn't figure out what is going on. The following silly minimal test produces the expected result with mkiv but not in mkxl.

Customize citation format of a bibliography (use the short form as reference format)
by Gerion Entrup 25 Apr '24

25 Apr '24

Hi, I'm trying to customize a cite format in a bibliography. Currently, I'm using the aps style which fits so far, except of the plain number as reference. In concrete, I want to change the following: - Use the first letter of the last name and the year as reference (this should be exactly the short form). It is more less also described here [1]. - Highlight publications of a certain author with an extra char (e.g. '>') Here is a minimal example (lets assume, every occurrence of Knuth should be highlighted): ``` \setupinteraction[state=start] \startbuffer[testdata] @Book{knuth1, author = {Donald E. Knuth}, title = {TEX and METAFONT. New directions in typesetting}, year = {1979}, publisher = {Addison-Wesley}, } @Article{someother, author = {Some Person and Some Otherperson}, title = {Another title}, year = {1900}, } \stopbuffer % enable tracing \enabletrackers[publications, publications.crossref, publications.details, publications.cite, publications.strings] \usebtxdataset[main][testdata.buffer] \usebtxdefinitions[aps] \setupbtx[dataset=main] \definebtxrendering[bibrendering][aps][dataset=main] % this seems to have no effect? \setupbtx[alternative=short] \starttext Knuth developed \TeX \cite[knuth1]. Several persons said something \cite[someother]. \placelistofpublications[bibrendering] \stoptext ``` It should be rendered as: ``` Knuth developed TeX [>Knu79]. Several persons said something [PO00]. [Knu79] D.E. Knuth, TEX and METAFONT. New directions in typesetting (Addison-Wesley, 1979). [PO00] S. Person and S. Otherperson, Another title, (1900). ``` How can I achieve that \cite[something] always renders in the short form by default? How can I customize that references to Knuth contain this extra '>'? How can I customize the APS style to also use the short form in the list of publications instead of numbers?

Re: which parameter is for adjust the distance between items in a list?

You are right. I shall change the parameter `inbetween` in `\setupitemize`.

Hi all, I’m slightly embarrassed because this should be easy, but I can’t figure out how to do this: in the tuc/tua file, I have the complete references of my document. How can I access it from within my Lua code? For instance, something like utilitydata.structures.references.collected.”MyReference”.references.realpage How can this be accessed? Thanks a lot and best wishes Thomas

thank you. just tried, not worked out yet. Here it is my text: ``` setuplist[height=0] \startitemize[n] \item It's impossible --- don't waste my time. \item It's possible, but not worth doing. \item I said it was a good ideal all along. \stopitemize ``` Now the distance between the items is equal to the blank space between paragraphs. I want to reduce it equal to the distance between the lines of a paragraph.

what are the interaction between \showframe and \realpageno in \startuseMPgraphic ?
by garulfo＠azules.eu 24 Apr '24

I can not figure out why this progress bar only works when \showframe is activated. When you comment on \showframe, it's as if \realpageno is at zero. (current version: 2024.04.01 08:59) \showframe \startuseMPgraphic{MonGraphisme_MP} numeric n ; n := \number\realpageno ; numeric m ; m := \number\lastpageno ; numeric h ; h := \overlayheight ; numeric w ; w := \overlaywidth ; numeric e ; e := 3mm; numeric r ; r := (((n-1)/(m-1))*w); fill fullsquare xscaled w yscaled e shifted (w/2, h/2) withcolor darkblue ; fill fullsquare xscaled r yscaled e shifted (r/2, h/2) withcolor darkred; \stopuseMPgraphic \defineoverlay [MonGraphisme_OL] [\useMPgraphic{MonGraphisme_MP}] \setupbackgrounds [footer] [rightmargin] [background={MonGraphisme_OL}] \starttext \dorecurse{10}{\input tufte\page} \stoptext Any clue is warmly welcome

documentation: parameters of \setuplist
by Henning Hraban Ramm 24 Apr '24

24 Apr '24

I tried to complete https://wiki.contextgarden.net/Command/setuplist, but I don’t understand all parameters. Can anyone explain these please: * state (start stop): what does this en-/disable? collecting entries? * label (yes no none Name): language dependent labels? as a prefix or what? * location (none, here): disable placement? when makes this sense? * aligntitle (yes no): align which part to what? * symbol (one two three none default): where is this used? Expect more questions… Hraban

Why don't footnotes appear in floats or figures?
by Joel 24 Apr '24

24 Apr '24

I'm three days out from sending my work to an editor, and found some serious problem: many footnotes just aren't rendering. I have a history text that uses ConTeXt-SBL for the citations, as such, it has lots of footnotes. Sometimes the footnotes are just in the main text, but sometimes also in figure captions, inside floats, inside tables that are inside floats, inside tabulations inside floats, etc. What I find alarming is it is frequently not rendering all of the footnote messages at the bottom of the page. The actual footnote number within the body is rendered, but no number is listed in at the bottom of the page. So I might see a list of footnotes, for instance, on page 1, I only get footnotes 1, 2, 3, 5, and 6, but 4 was mysteriously skipped. ---------------1 message2 message3 message5 message6 message After a lot of trial-and-error and checking logs and checking my BibTeX files for errors, running everything through BibTex Tidy, etc., and failures to make a minimum working example, I found a single pattern: If the footnote marker appears on the SAME page as the footnote text, it has no problem rendering the footnote. But, if ConTeXt decides to move a float a page or two later on--as it frequently seems to do---such that the footnote marker and footnote text at bottom of page should be on DIFFERENT pages, the footnote message at the bottom of the page won't render. I've seen some 2+ year old mailing list posts suggesting ConTeXt might have issues with footnotes; they appear to be similar to my issue--is that still a problem? Is there a fix or workaround? Old fixes I could finding in the mailing list don't seem to work with current versions of ConTeXt anymore. --Joel
