footnotes missing in heads
by Pablo Rodriguez 03 Sep '20

03 Sep '20

Dear list, the following minimal sample: \starttext \chapter{Chapter\footnote{Note}} \section{Section\footnote{Note}} \stoptext Using current latest (from 2020.09.02 20:37) doesn’t display the footnotes. I’m afraid this may be a bug. Could anyone confirm this? Many thanks for your help, Pablo -- http://www.ousia.tk

You can improve the second method with the following setup \setupsectionblock [frontpart] [after=\page] % after={\page[right]} Wolfgang

MKIV - LMTX difference: stripping of leading white space in verbatim text
by Christoph Reller 03 Sep '20

03 Sep '20

Dear List, I am using ConTeXt LMTX 2018.05.19 21:46. Consider the following MWE: \starttext \startLUA whatever \stopLUA \stoptext In contrast to ConTeXt MKIV, the leading four spaces in front of "whatever" are not removed when processing the verbatim text: MKIV output: whatever LMTX output: whatever Is there a way to get the old MKIV behavior back? Cheers, Christoph

\pdfextension obj stream file
by Alexander Grahn 03 Sep '20

03 Sep '20

Hello, \pdfextension obj stream file {...} stopped working in ConTeXt (TeXLive-2020). Here is a minimal example: \starttext test \immediate\pdfextension obj stream file {duck.mp3} \stoptext It produces an error: mtx-context | fatal error: return code: 256 ...4a3076dc514ba966a1fac9/formats/luatex/lpdf-ini-macro.lua:892: pdf.obj(): no "string" or "file" given 1 \starttext 2 >> test \immediate\pdfextension obj stream file {duck.mp3} 3 \stoptext mtx-context | fatal error: return code: 256 On the other hand, the LuaTeX versions compiles: test \immediate\pdfextension obj stream file {duck.mp3} \bye Kind regards, Alexander

PNG image inclusion resolution
by Christoph Reller 02 Sep '20

02 Sep '20

Dear List, I am using ConTeXt LMTX 2020.08.31 22:16. Consider the following MWE: \starttext \externalfigure[resolutionTest.png] \stoptext When comparing the output with ConTeXt MKIV, then the image size is extremely small. gimp reports the resolution of resolutionTest.png as 71.984 DPI. Is this a bug? (I cannot reproduce the shrinkage with hacker.png.) Also, I noticed that the "resolution" key when applied as: \externalfigure[resolutionTest.png][resolution=150] has no effect. What is the meaning of this key? Cheers, Christoph

Tagged PDFs from Context
by Karl Pettersson 02 Sep '20

02 Sep '20

Hi See this discussion. https://github.com/jgm/pandoc/issues/5409#issuecomment-678781349 Would it be possible to generate PDFs with headings tagged like H1, H2, H3, H4..., instead of using the H tag for all levels, which seems to be required for proper rendering with some screenreaders? It seems to me that it would require modfications to the Context source code. https://source.contextgarden.net/tex/context/base/mkiv/strc-tag.lua Any ideas? Best regards Karl Pettersson

Hello Is it possible to import a metapost extension into a file compiled with the lmtx engine ? I tried unsuccessfully with this example : %%%% begin test.tex \starttext \startMPcode input mp-scratch; Scratchversion:=3; draw Drapeau; draw Repeter("4"); draw Avancer("50"); draw Tournerd("90"); draw FinBlocRepeter; \stopMPcode \stoptext %%%% end test.tex Thanks Fabrice

strange behavior with \groupedcommand in recent versions of LMTX
by mf 02 Sep '20

02 Sep '20

Hello list, this is a MWE that worked right in MkIV and in LMTX versions (at least) until April 22nd, 2020. There's a macro, \wordorparagraphright, that takes one argument, makes a hbox with it and measures its width - if its width is less than \hsize, then it calls \wordright - if its width is more than \hsize, then it ends the current paragraph and starts a right-aligned paragraph with the argument There are two implementations in the MWE: one is through \groupedcommand, and that's the one that worked once and doesn't now. ---------------------------------------------------- \unexpanded\def\groupedwordorparagraphright{\dosingleempty\dogroupedwordorparagraphright} \def\dogroupedwordorparagraphright[#1]{\groupedcommand{\setbox\scratchbox\hbox\bgroup} {\egroup\ifdim\wd\scratchbox < \hsize \wordright{\unhbox\scratchbox} \else \par\penalty10000 \startalignment[flushright]\unhbox\scratchbox\stopalignment \fi}} \unexpanded\def\wordorparagraphright#1{% \setbox\scratchbox\hbox{#1} \ifdim\wd\scratchbox < \hsize \wordright{#1} \else \par\penalty10000 \startalignment[flushright]\unhbox\scratchbox\stopalignment \fi} \starttext \type{\wordorparagraphright} should use \type{\wordright} if its argument is narrower than \type{\hsize}, or make a right-aligned paragraph with it when it's wider. Below, \type{\wordorparagraphright} is tested with a short text, that has enough room on the same line. \blank Reference: \input ward\wordright{same line, right} \blank Implementation as a grouped command (it doesn't work): \input ward\groupedwordorparagraphright{same line, right} \blank Normal implementation, not as a grouped command (it works): \input ward\wordorparagraphright{same line, right} \stoptext ---------------------------------------------------- Unfortunately the grouped version is the one I need, because it's used in a register, and it would give an error if not defined through \groupedcommand: \setupregister[myregister] [pageleft=\wordorparagraphright\bgroup,pageright=\egroup] TIA, Massi

special chapter label
by jbf 02 Sep '20

02 Sep '20

Am working on a book where most chapters are simply labeled Chapter One, Chapter Two etc., and this has been achieved easily enough with \setuplabeltext[chapter=Chapter ] (also including \setupheads[conversion=Words] to get One, Two instead of 1 2). But several chapter labels need to have a date range after them, e.g. *Chapter Three: 1820-1880*. I have tried introducing a new \setuplabeltext[chapter=Chapter: 1820-1880 ] just before the \startchapter command, but this results in*:** * *Chapter: 1820-1880 Three* (and I also hope that introducing this does not also affect Chapter Four since that will have a different set of dates). How can I get a specific labeltext set up so that the result is *Chapter Three: 1820-1880*, and also ensure that other chapters either return to just the chapter number or, if needs be, can also indicate different date ranges? I have looked everywhere on the wiki for ideas to help me, but so far no luck. Julian

defining font family for several options
by jbf 01 Sep '20

01 Sep '20

Perhaps someone can assist me with the following query. I have a situation where I need to use more than one sans serif fonts (especially within complicated chapter heads). I currently have the following: \definefontfamily [mainface] [rm] [alegreya] \definefontfamily [mainface] [ss] [dax][tf=file:dax-regular] \definefontfamily [mainface] [mm] [alegreya] \setupbodyfont[mainface] \setupbodyfont[11pt] But what if I need to have, in addition to the Dax sans serif typeface, an additional sans serif typeface such as ITCAvantGarde? How do I declare that? Do I just give it another name, e.g. \definefontfamily[chapter][itcavantgarde] etc? If I did that, how then do I refer to it? Obviously not just as {\ss my text} since that would call in the dax font. Julian
