Does the ConTeXt distro come with a PDFViewer?
by Ramkumar KB 10 Oct '21

10 Oct '21

Hello Community, If my memory serves me correctly, I might have noticed (in one of the presentations during the recent ConTeXt meeting) that the distro comes with a PDFViewer. Is that a correct assumption? I am currently using a VSCode extension for PDFViewing but it does not work very reliably. Thank you very much, best regards, Ramkumar

You have to make the changes in the original file and afterwards generate the format file with context --make If everything works as expected report back and Hans can apply the fix on his machine to ensure they are included in the next release because when you make a update your changes are overwritten.

Something smells rotten in the state of luametatex...
by Thomas A. Schmitz 08 Oct '21

08 Oct '21

Hi all, I have a document here for one of my classes: xml processed via context, some layers, some two column paragraphs, a bibliography, nothing out of the ordinary. With mkiv, it compiles cleanly: mkiv lua stats > used engine: luatex version: 1.13, functionality level: 7420, banner: this is luatex, version 1.13.0 (tex live 2021) mkiv lua stats > used hash slots: 48846 of 65536 + 250000 mkiv lua stats > lua properties: engine: lua 5.3, used memory: 212 MB, ctx: 210 MB, max: unknown MB, hash chars: min(64,40), symbol mask: utf (τεχ) mkiv lua stats > runtime: 2.775 seconds, 119 processed pages, 119 shipped pages, 42.883 pages/second system | total runtime: 5.996 seconds When I compile the same document with luametatex, things slow down to a crawl: mkiv lua stats > used engine: luametatex version: 2.0921, functionality level: 20210903, format id: 594, compiler: gcc mkiv lua stats > tex properties: 740039 hash slots used of 2097152, 48372 control sequences, approximate memory usage: 36 MB mkiv lua stats > lua properties: engine: lua 5.4, used memory: 100 MB, ctx: 93 MB, max: 138 MB, symbol mask: utf (τεχ) mkiv lua stats > runtime: 27.509 seconds, 119 processed pages, 119 shipped pages, 4.326 pages/second system | total runtime: 139.458 seconds of 139.493 seconds So, it takes more than 20 times as long... The CPU of my computer goes up to 100 %, and the entire machine sometimes becomes unresponsive during the run. Obviously, I can't provide a MWE, but this seems bizarre. One thing I see on my terminal: there are hundreds of lines like this Overfull \hbox (0.8pt too wide) in paragraph at lines 18--18 6:17: [glue][glue]<l2r par><l2r [glue][boundary][hlist][penalty][glue][hlist][penalty] >[glue][glue] It's almost like some debug setting has been triggered. But that may be a red herring. Anyway, I just wanted to report this; maybe some bigger problem (with the binary or the format?) is lurking somewhere. All best Thomas

Test suite fonts/features-005.tex failing for me
by Bruce Horrocks 08 Oct '21

08 Oct '21

In the test suite, the file fonts/features-005.tex is failing for me on latest lmtx. All three items appear the same each time i.e. no small caps and no old-style digits on the second and third. <http://www.pragma-ade.com/context/latest/cont-tst.zip> Can anyone else reproduce this, please? — Bruce Horrocks Hampshire, UK

hatching an area without drawing its borders
by Damien Thiriet 08 Oct '21

08 Oct '21

Hi, I read the 2015 thread Hatch an area with Metapost (Metafun) and started playing with anglestriped. However in my maps I would like to get my shapes hatched with no borders drawn. How can I achieve it? path p; p := fullcircle scaled 50 randomized 5; draw p anglestriped (1,60,4); Damien Thiriet

Placing SVG icons and text side by side

How can I place an SVG icon "inline", i.e. side by side to some text? Here's my MWE ``` \useURL [github] [https://github.com/test] [] [github.com/test] \starttext \placefigure[none]{}{\externalfigure[github.svg][width=17.5pt]} \from[github] \stoptext ``` I have attached a screenshot of the output and the SVG file.

The big problem: for the next followtext, I need the circular arc between points z[23] and z[20]. But however I place the cutbefore and cutafter, I don't get the proper part of the circle. I'm looking at the right intersection points, as the red line shows, but the blue line shows that I'm not getting the right section of the circle. How can I get this section into the path S[20]? 2. Math... :-) Is there a better way to define three circles that are at exactly the same distance than my naive "scaled 1.3" and "scaled 1.5"? 3. TeX and metafun: is there a better way to have the followtext exactly centered between the two circles rather than just fiddle with the scale factor? 4. Or is there a better approach to my problem altogether? I'm trying to reproduce an illustration from a book, so I'm very open to suggestions here. I looked at the example in the metafun manual chapter 10.4, but I'm not sure if using an overlay and multiple \followtokens would be easier. Especially since there is the scary remark "This definition is not the right one!" in this chapter without any further explanation. I hope you all had a wonderful meeting last week. I was sad I couldn't come, I was in Paris for a conference, the first after 18 months, so I couldn't skip this one. Thanks and best wishes Thomas
