new upload
by Hans Hagen 08 Aug '21

08 Aug '21

Hi, I did a new upload. Attached is a document describing a new cheap (lmtx only) feature. It's probably not that useful for most users, because it is meant for somewhat extreme situations. but you never know.

Problem with colored font
by Marcus Vinicius Mesquita 07 Aug '21

07 Aug '21

Dear list, I'm trying to use the BabelStone Flags font, with colored flags of many countries, available freely under the SIL Open Font License 1.1 at: https://babelstone.co.uk/Fonts/Download/BabelStoneFlagsDual.ttf In the MWE below, there is a spurious “at” in the first time that the definition of the symbol for the Brazilian flag is used, but no problem when the definition for the flag of Portugal is used or even when the symbol for the Brazilian flag is used a second time. How to correct this behavior? MWE: \definefontfeature[colored][colr=yes] \definefontsynonym[flags][file:BabelStoneFlagsDual.ttf*colored at 7pt] \definesymbol[BR][\getglyphdirect{flags}{\char"F0023}] \definesymbol[PT][\getglyphdirect{flags}{\char"F00A1}] \starttext Brasil \symbol[BR] Portugal \symbol[PT] Brasil \symbol[BR] \stoptext -- Todas as coisas fatigam o corpo, salvo a música, que não fatiga nem o corpo nem seus membros, por ser descanso da alma, primavera do coração, distração do aflito, entretenimento do solitário, e viático do viajante.

Referencing fonts by path within ConTeXt
by Joey McCollum 07 Aug '21

07 Aug '21

Hi, I'm interested in packaging a ConTeXt project in a self-contained way, so that the environment/component/project .tex files, the bibliography .bib file(s), and fonts used for typesetting are all provided in one place. (The goal is that others can generate the PDFs themselves from the source files as long as they have a sufficiently recent version of ConTeXt installed.) The usual ConTeXt directory structure makes sense for most of this, but it doesn't address the possibility of accessing fonts locally. I think I could do this with a script that temporarily sets the OSFONTDIR variable to the local fonts directory and then invokes ConTeXt to typeset the project-level file, but I was wondering if there is an easier way to do this from within ConTeXt. Specifically, is there a way to specify a font via a local path with font setup commands in an environment file? Thank you! Joey

Setting a heading text on its own page with \setuphead
by Joey McCollum 07 Aug '21

07 Aug '21

Hi, I'd like to define my own class of heading derived from the "part" heading; in the MWE below, it's called "MyPart". I'd like this heading to have the following features: - Its title should appear in the ToC, but its number should never be printed in the ToC or in the text. - It should always start on an odd page. - Its text should be in a larger size than the text of the body, set in all caps, and set with extra letterspacing. - Most importantly, the title of the heading should appear on its own page without a header or footer. The text of the body should begin on the next odd page. I was hoping to accomplish all of this within the \setuphead command, and it seems like this should be possible, but in the following example, I'm not getting the text of the header at all: ``` \setuppagenumbering [alternative=doublesided, location=] %undo default page numbering in middle of header; doublesided option will ensure that the document has an even number of pages %Define an odd page break between books that omits headers and footers in blank pages \definepagebreak[blankpagebreak][yes,header,footer,right] %Setup body and title fonts (is any of this redundant, or can it be consolidated?): \definefontsynonym [EBGaramond] [name:EBGaramond-Regular] [features=default] \definefontfamily[garamond] [rm] [EBGaramond] [features={default}] \setupbodyfont[garamond, 12pt] \setupinterlinespace[18pt] %text line spacing \definefont[MyPartFont][EBGaramond at 24pt][line=36pt] %font command to be used for setting MyPart heading texts %Macro for adjusting kerning of MyPart heading texts (can any of this can be handled in the \definefont call?): \define[1]\MyPartTextCommand{% \kerncharacters[0.6666]%increase letterspacing \WORDS{#1}%set all letters in uppercase } %Macro for page break after MyPart headings: \define\AfterMyPart{% \page[blankpagebreak]% } %Define a new heading at the level of a part: \definehead[MyPart][part] \setuphead[MyPart][ number=no,%do not add a number to this heading page=blankpagebreak,%always start this on an odd page header=empty,%disable headers for this page footer=empty,%disable footers for this page align={flushleft, nothyphenated},%titling alignment settings textstyle=\MyPartFont,%set text style textcommand=\MyPartTextCommand,%set text formatting command commandafter=\AfterBookTitle%add a double page break afterwards ] %Setup header and footer text: \setupheadertexts[{\structureuservariable{booktitle}}\hfill][][][\hfill {\structureuservariable{booktitle}}] %even left, even right, odd left, odd right \setupfootertexts[\pagenumber][][][\pagenumber] %even left, even right, odd left, odd right %Ensure that whitespace respects the grid layout: \setupblank[line,fixed] \starttext \startMyPart[title={Title for Title Page}][booktitle={Title for Header}] \input knuth\par \input knuth\par \input knuth\par \input knuth\par \input knuth\par \input knuth \stopMyPart \stoptext ``` I expect there's something obvious that I'm missing, but any help is appreciated. Thank you! Joey

ECMAscript
by Henning Hraban Ramm 07 Aug '21

07 Aug '21

Hi Taco (et al.), for running the ECMAscript part of the CG journal, I cloned the repo from https://github.com/ccxvii/mujs/ and executed "make release". I copied the resulting files to my TeX tree: ll ~/lmtx/tex/texmf-osx-64/bin/lib/luametatex/mujs/ total 2832 -rw-r--r-- 1 hraban staff 517K 7 Aug 09:49 libmujs.o -rw-r--r-- 1 hraban staff 9,2K 7 Aug 09:49 main.o -rwxr-xr-x 1 hraban staff 413K 7 Aug 09:49 mujs* -rwxr-xr-x 1 hraban staff 408K 7 Aug 09:49 mujs-pp* -rw-r--r-- 1 hraban staff 2,9K 7 Aug 09:49 pp.o But apparently I need a libmujs.so – how do I make this?

Rotating pages
by Jeroen 07 Aug '21

07 Aug '21

For the following document, the last 3 pages are landscape, but I would like to have the pdf-ed rotated so they are in the pdf document portrait, ie rotated 90 degree to the left but leave the page as how they are now. Is there an easy way to achieve this? \startbuffer[apx] \setuppapersize[ A4,landscape] \setuppagenumbering[ location={footer,center}] \setbreakpoints[compound] \starttext \startsection[title={MyTitle},ref={apx}] \dorecurse{10}{\input zapf\par} \stopsection \stoptext \stopbuffer \savebuffer[list=apx, file=apx.tex] \starttext \startbodymatter \dorecurse{10}{\input zapf\par} \typesetfile[\jobname-apx.tex][--purgeall][object=no, width=0pt] \stopbodymatter \startappendices \getfiguredimensions[\jobname-apx.pdf] \dorecurse{\noffigurepages} {\startTEXpage \externalfigure[\jobname-apx.pdf][page=\recurselevel] \stopTEXpage} \stopappendices \stoptext

lpeg pattern in function
by Marcus Vinicius Mesquita 07 Aug '21

Dear list, in the mwe below, the expected result is ok for most entries but fails when the word contains the letters ó or ô. We get zoolco instead of zoológico, and termtro instead of termômetro. What am I doing wrong? mwe: \def\stripnumber#1% {\cldcontext{lpeg.match(lpeg.stripper("[¹²³⁴⁵⁶⁷⁸⁹⁰]"), [==[#1]==])}} \starttext \stripnumber{árbitro⁶} \stripnumber{ébano¹} \stripnumber{ícone⁸} \stripnumber{zoológico⁰} \stripnumber{eletroacústico⁹} \stripnumber{trânsfuga⁷} \stripnumber{farmacêutico¹} \stripnumber{maître²} \stripnumber{termômetro³} \stripnumber{noûs⁴} \stoptext -- Todas as coisas fatigam o corpo, salvo a música, que não fatiga nem o corpo nem seus membros, por ser descanso da alma, primavera do coração, distração do aflito, entretenimento do solitário, e viático do viajante.

New error "page order problem in tree at page"
by Rik Kabel 07 Aug '21

07 Aug '21

With today's LMTX release I see the warning: backend > tags > beware: page order problem in tree at page 1 This appears to be recently introduced to the code. Should it be a concern? If so, where should I look to remedy it? -- Rik

Code document and simpleslides and create in one go the document with simpleslides added
by Jeroen 06 Aug '21

06 Aug '21

Is there an easy way to write a Context document and also code simpleslides in the same document so that the simpleslides are automatically added to the document as for example an appendix? Ie one tex document with Context code, perhaps with some \input and something like a two-pass job. I was thinking if the simpleslides could be saved as a number of png images and then with the recurse add them to the document with placefigure. Jeroen

copies from \setupinteractionscreen not working?
by Pablo Rodriguez 06 Aug '21

06 Aug '21

Dear list, I have the following sample: \setupinteractionscreen[copies=5] \starttext \dorecurse{5}{\input zapf\par} \stoptext The resulting file from current latest (2021.07.30 00:57) contains the following /ViewerPreferences dictionary: /ViewerPreferences << /Duplex /Simplex /PickTrayByPDFSize true /PrintScaling /None >> I’m afraid that "copies" isn’t generating the proper /NumCopies entry in the /ViewerPreferences dictionary. Could anyone be so kind to confirm this? Many thanks for your help, Pablo -- http://www.ousia.tk
