'lua.registercode' bug in latest beta
by Li Yanrui (李延瑞) 26 Nov '17

26 Nov '17

Hi, Using '\ctxloadluafile' can get an error: ``` ..ext/tex/texmf-context/tex/context/base/mkiv/luat-cod.lua:50: bad argument #1 to 'gmatch' (string expected, got nil) ``` It seems to be caused by 'if options ~= ""' in `lua.registercode'. That empyt string should be 'nil'? -- Best regards, Li Yanrui (李延瑞)

definefallbackfamily and uppercasedoublestruck not working?
by Mikael P. Sundqvist 25 Nov '17

25 Nov '17

Hi! I use the Neo Euler which has no doublestruck characters. Maybe I use old code, but I really think that the following has worked before: %%% \definefontfamily [mainface] [rm] [TeX Gyre Pagella] \definefallbackfamily [mainface] [mm] [TeX Gyre Pagella Math][range=uppercasedoublestruck] \definefontfamily [mainface] [mm] [Neo Euler] \setupbodyfont[mainface,12pt] \starttext \startTEXpage[offset=3pt] Test: $\blackboard C$ or $\mathbb C$ \switchtobodyfont[pagella] Test: $\blackboard C$ or $\mathbb C$ \stopTEXpage \stoptex %%% I would expect doublestruck letters in the output on the first line. The resulting file, compiled with a fresh Standalone, is attached. Best regards, Mikael

extreme tables cell spanning interference: a bug?
by mf 25 Nov '17

25 Nov '17

Dear list, i've found that a cell spanning across multiple rows in extreme tables interferes with a cell spanning across multiple columns on a common row. Ok, if that is not so clear, try this: ---------------------------- \starttext The first cell spans across 3 rows. The cell in the last row should span across 2 columns, but it's actually one column large. \startxtable[align={middle,lohi}] \startxrow \startxcell[ny=3] 3x1 \stopxcell \startxcell 1x1 \stopxcell \startxcell 1x1 \stopxcell \stopxrow \startxrow \startxcell 1x1 \stopxcell \startxcell 1x1 \stopxcell \stopxrow \startxrow \startxcell[nx=2] 1x2 (why 1x1?) \stopxcell \stopxrow \stopxtable Now the first cell spans across 2 rows, and the first cell of the last row spans across 2 columns as expected. \startxtable[align={middle,lohi}] \startxrow \startxcell[ny=2] 2x1 \stopxcell \startxcell 1x1 \stopxcell \startxcell 1x1 \stopxcell \stopxrow \startxrow \startxcell 1x1 \stopxcell \startxcell 1x1 \stopxcell \stopxrow \startxrow \startxcell[nx=2] 1x2 (ok!) \stopxcell \stopxrow \stopxtable \stoptext ---------------------------- Best wishes, Massi

Adjust rendering of BibTeX entries
by Dr. Thomas Möbius 23 Nov '17

23 Nov '17

Dear list, I would like to render BibTeX-entries with the provided APA-style, however, in the text use superscript cross references. I have the following issues, which I don't know how to resolve. I was hoping, you could help me. 1. When choosing the style APA, the change to \setupcite seems to be ignored, see the minimal example below. (When changing alternative=apa back to alternative=ams, it works again.) 2. As I am citing bibliography entries with numbers, adding letters to the end of the publication years makes no sense. How can I loose the letters? Now, also the provided AMS-style adds these letters, which I don't think should be the case, too. 3. The edition field when citing a book is rendered wrong. It should be 7th edition followed by a period. (Compare this with the ams-style, where the edition field is rendered correctly.) How can I add the period and automatically add the st, nd, rd, th to a edition number? 4. Say, I would revert back to AMS-style but using superscripts rather than the [#Number] default. How can I loose the square brackets in the reference section? Thank you very much in advance. Thomas ----example.tex---- \setupbibtex[database={references},sort=author] \setuppublications[alternative=apa,sorttype=authoryear,numbering=yes] \setupcite[num][ left=\raisebox{1ex}\hbox\bgroup\tfxx, right=\egroup, lastpubsep={, }] \starttext \title{Test with APA} \section{Some text} This\cite[Mustermann:2014, Doe:2012a] and that,\cite[Doe:2012b] also that\cite[Doe:2012a] and this book.\cite[Mustermann:2001] \section{References} \placepublications [criterium=text] \stoptext ----example.bib---- @article{Mustermann:2014, title = {One hell of a title}, author = {Max {Mustermann}}, journal = {SomeJournal}, year = 2014, volume = 63, number = 2, pages = {289-298} } @article{Doe:2012b, title = {Another title}, author = {John {Doe}}, journal = {SomeJournal}, year = 2012, volume = 3, number = 2, pages = {189-198}, } @article{Doe:2012a, title = {Foo Bar Zap}, author = {John {Doe}}, journal = {SomeJournal}, year = 2012, volume = 4, number = 1, pages = {89-92}, } @book{Mustermann:2001, title = {How does this work?}, author = {Max {Mustermann}}, publisher = {Springer}, year = {2014}, edition = 7, address = {Berlin/Heidelberg} }

Textbackground offset with multi-col paragraphs
by Thomas Floeren 23 Nov '17

23 Nov '17

Hi, I noticed that with one of the recent betas the right offset of my textbackgrounds doesn’t work properly anymore when the textbackground contains a multi-column “paragraph”. A minimal: \defineparagraphs [TestPar][n=2, distance=7mm] \setupparagraphs [TestPar][1][width=2em] \definetextbackground [CB][ location=paragraph, backgroundcolor=gray, leftoffset=.3em, rightoffset=.3em, topoffset=.3em, bottomoffset=.3em, frame=off ] \starttext \starttextbackground [CB] \dorecurse {40} {a b c } \stoptextbackground text \starttextbackground [CB] \startTestPar img \TestPar \dorecurse {40} {a b c } \stopTestPar \stoptextbackground \stoptext The first box is OK and as expected. But with the second one (containing a “paragraph”) the right offset gets miscalculated, so that the text runs into the edge of the background. With a beta from July or so the behavior was still OK. Thanks for any advice, best, -- Tom http://dflect.net/context-typeset-tool/

synctex and TeXShop problem
by Alan Bowen 22 Nov '17

22 Nov '17

With the latest betas, I see that with the TeXShop Engine #!/bin/tcsh # Before using this engine, you must run the following command once in Terminal: luatools --generate set path= ($path /usr/texbin /Users/bowen1/Dropbox/ConTeXt/tex/texmf-osx-64/bin) mtxrun --script context --autogenerate --file-line-error "$1” and \setupsynctex[state=start, method=max] in the source file, the requisite *filename*.synctex auxiliary file is produced on processing. But I am still not getting any linkage between the source file and the preview file, that is, clicking on one does not have any effect on the other. Is there something else that I need? I am running ConTeXt ver: 2017.11.15 with macOS 10.13.1. Alan

Setting the footnote symbol
by Idris Samawi Hamid ادريس سماوي ح امد 17 Nov '17

17 Nov '17

Der gang, For the following \definefont scenario, the footnote symbol in the main text is not raised: ======= \setuppapersize[letter][letter] % \setupbodyfont[schola,12pt] \definefont[PagellaRegular] [texgyrepagella-regular.otf at 14pt] \definefont[PagellaRegularSmall][texgyrepagella-regular.otf at 12pt] \setupwhitespace[big] \setuplayout[width=4.5in,height=5.5in,backspace=2in] \setupnotation[footnote][style={\PagellaRegularSmall}, % text style of the footnote text numbercommand=\PagellaRegularSmall, % symbol-font style in the footnote titlestyle={\PagellaRegularSmall}] % Why is this necessary? \setupnote [footnote][textcommand={\PagellaRegularSmall}] % symbol-font style in the main text \noheaderandfooterlines \starttext \PagellaRegular \startframedtext[width=4.5in,offset=0pt] \startlocalfootnotes Hence in Met VII, where Aristotle debates with masterly penetration how to meet the claim of substance to be at once universal, intelligible, and definable, and at the same time unique and individual, the singular is at length superseded on the throne of substance by the infima species. \startfootnote Or \quotation{materiate form,} as Aristotle also calls it because it attains existence in a material embodiment and cannot be defined without reference to matter, though matter is itself indefinable. The discussion is interspersed with criticism of the forms. Aristotle attacks the theory as a purely arbitrary individualisation of universals, and the detail of the polemic, as well as the context, suggest that he is attacking Plato not for divorcing infimae species from singulars, but for separating and reifying genera taken apart from species. [\textellipsis] \stopfootnote\ That is to say the genus is taken to be fully actualised in its infimae species, and its further differentiation into singulars is treated as irrelevant. \placelocalfootnotes \stoplocalfootnotes \stopframedtext \stoptext ======= What do we need to do to get a raised footnote symbol in the main text (line 6 of the pdf)? Thanks in advance. Best wishes Idris -- Idris Samawi Hamid, Professor Department of Philosophy Colorado State University Fort Collins, CO 80512

getting metafun positions within (displayed) math mode
by Sanjoy Mahajan 17 Nov '17

17 Nov '17

Dear ConTeXters, For my sins, and to make students unhappy all over the world, I am writing another book: _A Student's Guide to Newton's Laws of Motion_ (for Cambridge University Press, aka CUP). As partial compensation, I convinced CUP that I may typeset it in ConTeXt and deliver them PDF. Being hopefully a guide actually useful to students, it will annotate every symbol in important equations, a feature cribbed from the first book of the _Student's Guide_ series, Dan Fleisch's _A Student's Guide to Maxwell's Equations_. I've attached an image of what such an annotated equation looks like (from page 2 of Fleisch's book). It's like a labeled part diagram (say, for a laptop), where each part (here, each symbol) is connected with an line to its explanation. I'm trying to do so with a combination of ConTeXt, MetaPost/MetaFun, TikZ, and whatever else might work. But I am a bit stuck at the following spot. My plan is to use MetaFun to get the coordinates of each symbol in a (displayed) equation and then, with MetaFun, connect those symbols to mini-paragraphs of explanation that surround the equation. But I am stuck on how to use \hpos in math mode. I'd like to do something like: \startformula \hpos{n1}{\sum}_{\hpos{n2}{0}}^{\hpos{n3}{1}} \stopformula to get the locations of the nodes n1, n2, and n3 without interfering with the math typesetting -- e.g., the engine should still know that \sum is in display-math mode, so it should be large and have its sub- and super-scripts below and above it, rather than next to it. However, the \hpos hides its argument in an \hbox, and thus hides it from the math layout. Thus, I have to do something like this minimal example: \starttext \startformula \sum_0^1 % what it should look like \quad \hpos{n1}{$\displaystyle\sum$}_{\hpos{n2}{$0$}}^{\hpos{n3}{$1$}} \stopformula \stoptext The hpos'ed version after the \quad looks different, even after the \displaystyle hack. Is there a version of \hpos for math mode? That would be the cleanest solution, because who knows what else would be needed for other cases, even if the limits can be placed correctly. Or is there a better way to annotate equations? (TikZ seems to have the same issue, in that it cannot see into equations.)

Metapost: How to get total number of pages?
by Procházka Lukáš Ing. 17 Nov '17

17 Nov '17

Hello, it seems that there is 'PageNumber' variable (macro) available within MP code, maybe introduced by 'StartPage', within MP. How do I get total number of pages or last page number within MP (in Ctx: \totalnumberofpages, \lastpage)? TIA. Best regards, Lukas -- Ing.
