Dear list, I have the following sample: \starttext \startitemize[n] \startitem Item\stopitem \startitem Item\stopitem \startitem Item\stopitem \startitem Item\stopitem \stopitemize \startitemize[a, packed] \startitem Item\stopitem \startitem Item\stopitem \startitem Item\stopitem \startitem Item\stopitem \stopitemize \stoptext I’m afraid that packed item lists are misbehaving. Could anyone confirm this? Pablo -- http://www.ousia.tk

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 03 Sep '20

03 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

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
