A book with sections
by Gerben Wierda 24 Oct '21

24 Oct '21

I’d like a book with chapters to have sections/parts, e.g. something that groups a few \chapter elements together. Is there support for this in LMTX? I.e. in such a way that it also shows up in the table of contents?

No page number is done by surpressing headers with: \setuphead[part][placehead=yes, header=empty]% or none I hope it helps, Pablo -- http://www.ousia.tk

How to enable the use of the blackboard font in modern ConTeXt
by Gerben Wierda 23 Oct '21

23 Oct '21

I’m back to an attempt to migrate my old mkii project to lmtx One thing I haven’t been able to find yet is how to use the blackboard font. {\blackboard Q} Doesn’t do anything. It also doesn’t give an error.

Hi, I include images with a variable via pandoc in a externalfigure directive. These images can be jpgs, pngs, pdfs and svgs.

Hi, I cleaned up some more backend code. There were some mails about dates and such and although the date field in setupinteraction works ok a more drastic overload is doen with directives. The reason is that the fact that we can set the date (and traler) is only because it permits generating pdf files that can be compared. No date as a bad idea anyway. \setupinteraction[title=My Title] % \enabledirectives[backend.date=2034-06-07] \enabledirectives[backend.date=no] \enabledirectives[backend.trailerid=no] \starttext \startTEXpage \blackrule[height=1cm,depth=0cm,width=4cm,color=darkred] \stopTEXpage (there always were command line options for it) More interesting is asome new experimental code: \starttext \dostepwiserecurse{40}{110}{2}{ \startTEXpage[offset=4mm,width=#1mm,align={stretch,normal,tolerant}] \showmakeup[penalty]% \orphanpenalties 4 4000 3000 2000 1000\relax \updateparagraphpenalties \samplefile{tufte} \par \stopTEXpage } \stoptext it's an addendum to the widowpenalties and clubpenalties introduced by etex but this time it's horizontal; the orphan penalties will be inserted before spaces (aka spaceskip, xspaceskip and zerospaceskip glue) so in this case 4000 between the last two 'words' and this trickery can be used to make sure that the last line is not too short \orphanpenalties 4 4000 3000 -12000 1000\relax is also intereting it's work in progress (i need to play more with it and figure out nice values for context) .. there might be more such 'simple' useful tricks Mikael: you can test the math cheat (doesn't make the font nicer). Pablo : transparencies should work again (wrong alias fixed). Michal: you can check the dates (as for sure i messed up something).

vertical align in combination
by Pablo Rodriguez 22 Oct '21

22 Oct '21

Dear list, I have the following sample: \starttext \setupexternalfigure[location=default] \startcombination[nx=3, ny=2, location={middle}] {\externalfigure[mill.png][width=.25\textwidth]} {\externalfigure[cow.pdf][width=.25\textwidth]} {\externalfigure[cow.pdf][width=.25\textwidth]} {\externalfigure[spider.eps][width=.25\textwidth]} {\externalfigure[hacker.png][width=.25\textwidth]} {\externalfigure[mill.png][width=.25\textwidth]} \stopcombination \stoptext The first line has the images vertically centered, but the second line has them aligned to the top. Using "align=middle" made no difference. How could I get all lines with images vertically centered? Many thanks for your help, Pablo -- http://www.ousia.tk

\rotate[rotation=270] adds extra vertical space
by Pablo Rodriguez 22 Oct '21

22 Oct '21

Dear list, I have the following imposition sample: \startbuffer[newbuff] \showframe\showgrid \setuppapersize[A3, landscape] \setuplayout[width=middle] \starttext \dorecurse{4}{\null\page} \stoptext \stopbuffer \startmode[*first] \savebuffer[newbuff][A3page.tex, prefix=no] \executesystemcommand{context --purgeall A3page.tex} \stopmode \showframe \setuplayout[page] \setuppapersize[A5][A4, landscape] \setuparranging [2UP] \setupinteractionscreen[option={landscape, paper}] \starttext \doiffile{A3page.pdf} {\def\Doc{A3page.pdf} \getfiguredimensions[\Doc] \dorecurse{\noffigurepages} {\ifodd\recurselevel \rotate[rotation=90] {\externalfigure[\Doc][page=\recurselevel, width=\textheight]} \else\rotate[rotation=270] {\externalfigure[\Doc][page=\recurselevel, width=\textheight]} \fi}} \stoptext I’m afraid that if rotation values are 270 or 180, the imposed page has an extra vertical space before. I think this might be a bug. Or I don’t know what I might be missing. Many thanks for your help, Pablo -- http://www.ousia.tk

mp-geo Metapost package with ConTeXt
by Gavin 22 Oct '21

22 Oct '21

Hello ConTeXters, I’d like to use the mp-geo Metapost package with ConTeXt to draw simple globes viewed from various directions. The package is here: https://melusine.eu.org/syracuse/poulecl/mp-geo/ It looks like the last update was 2008 and I don’t read French, so I though my chances of getting anything to work were pretty small. However, I was pleasantly surprised that this MWE found the mp-geo package, the necessary Metapost files in the ConTeXt installation, and the data files. \starttext \startMPcode input mp-geo; figure(-10u,-10u,10u,10u); Mercator(3,48,30); fin; end \stopMPcode \stoptext While all of the files were found, it did not produce a globe. Instead I got an error complaining about an invalid character in the data files. This error is repeated for about 20 files (a small fraction of the total). I put the first error and its data file below. All the others are identical with different .dat files. Maybe it’s just an encoding mismatch or a hidden character I can easily delete or replace. On the other hand, maybe I shouldn't even be attempting this? 2008 is a long time ago in ConTeXt time. Feel free to tell me this project is crazy, but if you have an idea how I can make this work, I’d really appreciate it! It looks like a fun package. Thanks! Gavin Error Log: (This error log below is actually from running Metapost directly on just the .mp file with the metapost code above. This error log is slightly more clear in its formatting than the ConTeXt log, but contains the same information.) !

Hi all, in a minimal example \starttext \externalfigure[test.svg][conversion=mp] \stoptext renders fine. I my real world project white background is rendered black.
