compile > unknown scanner 'dimenension'
by autumnus 22 Feb '25

22 Feb '25

hi, version : 2025.02.19 14:35 os : macos issue : tokens > compile > unknown scanner 'dimenension' It seems that the latest version will have a trivial issue with the terminal at compile time. It prompts in the terminal, but it doesn't interrupt the compilation. I don't know if I'm the only one with this problem. %%% \starttext \contextversion \stoptext %%% autumnus

Trouble with this formula
by Ursula Hermann 21 Feb '25

21 Feb '25

Dear List, I have a trouble with this formula, because, I would like to have c + d also in the matrix, but it is not working. \starttext \startformula \startmathmatrix[fences=doublebar] \pmatrix { a + b\NR} { c + d \NR} \stopmathmatrix \stopformula \stoptext And another question too: I would like to need the command \parallel, instead of the fences, how can I make them big? Many thanks Uschi

\pi not defined in latest MkIV
by Max Chernoff 20 Feb '25

20 Feb '25

Hi Hans, \pi doesn't seem to be defined in MkIV anymore. I'm using the latest from the standalone distribution, although the issue is also present in the TL25 pretest. Minimal example: % engine=luatex \startTEXpage \m{\pi} \stopTEXpage This was originally reported on the TeX Live list: https://tug.org/pipermail/tex-live/2025-February/051173.html Thanks, -- Max

outlinetext, fractions, and square roots
by Florent Michel 20 Feb '25

20 Feb '25

Hi, When experimenting with outlinetext, I found it generally works well for both text and equations but seems to fail for fractions or square roots. The code below demonstrates the issue: ____________________________ \startMPpage draw outlinetext("$\frac{1}{\sqrt{2}}$"); \stopMPpage ____________________________ The ‘1’ and ‘2’ seem to be at the right positions, but the fraction bar and horizontal part of the radical are missing. Is there a different fonction I should use for getting the outlines of equations? Best regards, Florent

MetaPost behaviour differs between standalone and \startreusableMPgraphic
by Pavneet Arora 20 Feb '25

20 Feb '25

I am in the process of converting a bunch of old TikZ notepaper templates to native ConTeXt and MetaPost. This is a part of a project to generate notebooks with documentation data and then blank pages appended to fill out full sheets, and then collated in a particular order for trimming and binding. As such I rely on Imposition. I am having issues with the various techniques of trying to duplicate a MP graphic across the pages using \[start|stop]MPcode \[start|stop]useMPgraphic, etc. But that is a discussion for another time. The method that I found to work was to use \[start|stop]reusableMPgraphic along with overlays I am still struggling with some MetaPost code that works fine in standalone but not when included in a ConTeXt document. With standalone MP, we get thicker lines on major increments as expected. When the same code is included in a ConTeXt document the thicker lines are only drawn up a certain number and then stop --- presumably the mod function returning a non-zero result when it really shouldn't? Here are the MWEs: >>> ConTeXt % Paper size and layout {{{2 \definepapersize | [PocketPage] | [width=2.75in,height=4.25in] \setuppapersize[PocketPage][letter,landscape] % }}}2 % MetaPost template for graph paper for pocket sized notebook (2.75" W x % 4.25in H). {{{2 \startreusableMPgraphic{graph} minor=2mm;| | % Minor lines, each every 2mm major=8mm;| | % Major lines, each every 4mm ┆ ┆ ┆ ┆ % major must be a multiple of minor z1 = (0,0);| % lower left corner % z2 = (2.75in,4.25in)-z1;| % upper right corner z2 = (2.75in,4.25in)-z1;|% upper right corner % Use the very thin pen pickup pencircle scaled 0.1; % Draw the vertical lines for i=minor step minor until (y2-y1): ┆ if (i mod major)=0: ┆ ┆ pickup pencircle scaled 0.3; ┆ fi; ┆ draw (z1 shifted (0,i))--((x2,y1) shifted (0,i)) withcolor .4white; ┆ if (i mod major)=0: ┆ ┆ pickup pencircle scaled 0.1; ┆ fi; endfor; % Draw the horizonal lines for i=minor step minor until (x2-x1): ┆ if (i mod major)=0: ┆ ┆ pickup pencircle scaled 0.3; ┆ fi; ┆ draw ( z1--(x1,y2) ) shifted (i,0) withcolor .4white; ┆ if (i mod major)=0: ┆ ┆ pickup pencircle scaled 0.1; ┆ fi; endfor; \stopreusableMPgraphic \defineoverlay[OLgraph][\useMPgraphic{graph}] \setupbackgrounds[page][background=OLgraph] % }}}2 \starttext hello. \stoptext <<< >>> Standalone MP beginfig(1) margin=0mm; % Margin of the graph paper minor=2mm; % Minor lines, each every 1mm major=8mm; % Major lines, each every 10mm % major must be a multiple of minor z1 = (margin,margin); % lower left corner z2 = (2.75in,4.25in)-z1; % upper right corner % % Use the thick pen first % pickup pencircle scaled 0.5; % % Draw the frame % draw z1--(x1,y2)--z2--(x2,y1)--cycle withcolor .5white; % Use the very thin pen pickup pencircle scaled 0.1; % Draw the vertical lines for i=minor step minor until (y2-y1-minor): if (i mod major)=0: pickup pencircle scaled 0.3; fi; draw (z1 shifted (0,i))--((x2,y1) shifted (0,i)) withcolor .4white; if (i mod major)=0: pickup pencircle scaled 0.1; fi; endfor; % Draw the horizonal lines for i=minor step minor until (x2-x1-minor): if (i mod major)=0: pickup pencircle scaled 0.3; fi; draw ( z1--(x1,y2) ) shifted (i,0) withcolor .4white; if (i mod major)=0: pickup pencircle scaled 0.1; fi; endfor; endfig; end; <<< advTHANKance -- Pavneet Arora m: +1 647-406-6843 Waroc Informatik e: pavneet_arora(a)waroc.com

Are paths resolved relative to file location or calling location?
by denis.maier＠unibe.ch 18 Feb '25

18 Feb '25

Hi, I have a (simplified) project structure like this: root-folder /asset /tex /results /source My tex file is stored under assets, the source is an xml file under source, the pdf should be saved under results. If I call context from within the assets folder, the pdf is created as expected, but if I call context from the results folder, I get an error message saying that the xml file is not found. As the file is created properly when I call context from the assets folder, I assume context performs lookups based on the calling location (not the file location). Is that correct? Is there a simple way to call context from the results folder and still have the sources found, or do I have to call context from the assets folder and copy/move the result afterwards? Best, Denis

Math hat misplaced in Libertinus
by Gavin 18 Feb '25

18 Feb '25

The hat accent is misplaced in Libertinus. I just noticed this in the LMTX from January. It is still the case in the latest LMTX. \usetypescriptfile[libertinus] \setupbodyfont [libertinus,12pt]% \startTEXpage[offset=1pt] \m{ \hat v \neq \vec v } \stopTEXpage This problem is not present in the TexLive 2024 version of LMTX. Thanks! Gavin
