Hi, I updated lmtx ... there are a few fixes for issues reported on the list. In the perspective of updating math the - otherwise unchanged - mkiv variant has also been updated a little. No new commands, just some (already old) experimental font related features gone and replaced by a combined one inspired by what we do in lmtx. In our opinion on the average it should not come out worse.

Spacing in \unit
by Gavin 22 Oct '22

22 Oct '22

Hi list, I made a small example with all of the issues I am trying to fix for the \units command. The first formula below uses the \unit command, but produces strange spacing. The second formula produces the desired spacing, without using the \unit command. \showmakeup[mathglue] %\mathspacingmode=1 \starttext \startformula \unit{1.23e5 kg m^2/s^2} + \unit{8.64e5 W s} = \unit{9.87e5 newton m} \stopformula \startformula 1.23\mathord\times10^5\,{\rm kg\mathord\cdot m^2/s^2} + 8.64\mathord\times10^5\,{\rm W\mathord{\cdot}s} = 9.87\mathord\times10^5\,{\rm N\mathord{\cdot}m} \stopformula \stoptext I’m trying to fix four issues: - No space between the number and the following units. Should be a thin space. - No space between the units and the following symbol (+ and = above). Should be appropriate “bin" or “rel" space. - Too much space around the \cdot in the units. Should be treated like an “ord" when used to separate units. - Too much space around the \times in the scientific notation. Should be treated like an "ord" when used in scientific notation. (I'm not sure there is consensus on this.) Some of these seemed like things I could fix myself, so I dug into phys-dim.mkxl to see what I could do. The good news is that I didn’t break anything. The bad news is that nothing I did seemed to have any effect – including deleting phys-dim.mkxl entirely! I double checked that I was working on the same installation used for typesetting. Is the code used for \unit now somewhere else? These issues only occur in math mode, and \unit handles comma separators correctly, unlike \digit. I’d like to get some sort of temporary patch for at least some of these issues, even if I need to write it myself. I use \unit everywhere in physics problems sets for students and in keys that I share other teachers. Any guidance is appreciated! Gavin P.S. I’m working on a more comprehensive test file, but its not ready yet.

Setting the size of \small
by Leah Neukirchen 22 Oct '22

22 Oct '22

Hi, playing around with \definebodyfontenvironment with latest LMTX, I found this possibly buggy behavior: \definebodyfontenvironment[12pt][small=6pt] % x=6pt works here \setupbodyfont[12pt] \starttext normal {\tx tx} {\small small} \stoptext With \definebodyfontenvironment[12pt][x=6pt] I can resize \tx fine, but for \small it doesn't work. -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/

\showstruts displaces text in LMTX
by Pablo Rodriguez 20 Oct '22

20 Oct '22

Dear list, compiling the following sample with current latest (2022.10.15 10:37): \showframe \showstruts \setuppapersize[A6] \setupnotation[footnote] [alternative=serried] \starttext a\footnote{\input zapf} \stoptext I get the text in the footnote is displaced. It only happens with LMTX (not with MkIV) and not with previous latest. Could anyone confirm the issue? Many thanks for your help, Pablo

Floating Figure in framed-environment
by Oliver Sieber 20 Oct '22

20 Oct '22

Dear ConTeXt Users I am relatively new to context and I am suffering with a problem with the framed environment. I want to use a framed textbox for Definitions in my script. I also want to use floating figures. But this does not work and I haven’t found out why. Maybe I totally use it the wrong way. I would appreciate if someone could help me or has a tipp. Here is an example code, where the figure does not behave as expected, i.e. the figure is behind the text: \starttext \framed[corner=round, rulethickness=2pt, width=\textwidth, align=flushleft, offset=1em,background=color,framecolor=black] {{\bf Definition: Hello World} \blank[medium] \placefigure[right, none]{This is an example of a logo.}{\externalfigure[dummy]} Carrot cake tiramisu lollipop dragée lollipop marshmallow carrot cake sweet pastry. Tiramisu danish jelly tootsie roll tart gummi bears. Carrot cake chupa chups cake wafer lemon drops lemon drops tiramisu. Chocolate lemon drops sugar plum cheesecake jelly beans sugar plum. Tootsie roll cupcake jujubes pie chocolate bar bear claw chupa chups shortbread. Candy candy canes jelly-o jelly beans sugar plum muffin danish donut. Bonbon lemon drops powder jujubes marshmallow biscuit halvah. Powder carrot cake caramels chocolate cake carrot cake jelly-o. Topping danish tootsie roll gummi bears oat cake jujubes. Sweet candy canes cotton candy pie topping. Jelly-o carrot cake ice cream lemon drops macaroon gummies lemon drops tiramisu chocolate cake. Cupcake sugar plum shortbread gummi bears tootsie roll. Chocolate cake sugar plum macaroon candy canes chocolate bar donut cake icing tootsie roll. } \stoptext Best regards Oli

TeXGyre Heros on Firefox
by juh 19 Oct '22

19 Oct '22

Dear all, there were some discussions on pdf viewers on the list and I know that things are not always fine. I now have a problems with the Firefox pdf viewer and TeX Gyre Heros. The font looks uneven in FF, no problems elsewhere. When I scroll into the pdf to set the display to 150% or more the font shows up just fine. So it seems to be a display problems with firefox. I tried several pdf versions no change. My configuration: \definefontfamily[mainfont][serif][texgyreheros] \definefontfamily[mainfont][sans] [textgyreheros] \definefontfamily[mainfont][mono] [texgyrecursor][features=none] \definefontfamily[mainfont][math] [texgyrepagellamath] \definefallbackfamily [mainfont] [rm] [Latin Modern Math] [scale=0.925, range=0x22C0] \definefontfeature[smallcaps][script=latn, protrusion=quality, expansion=quality, smcp=yes, onum=yes, pnum=yes] \setupalign[hz,hanging] \setupitaliccorrection[global, always] Is there anything I can do? And the is another issue: To my big surprise ArialBold MT is included into the file. I am using the current lmtx. If you want to see the effect, download the pdf. https://www.hostsharing.net/publikationen/vereinshandbuch/ Just click on "Anonym herunterladen" no need to register.

new upload
by Hans Hagen 19 Oct '22

19 Oct '22

Hi, I uploaded a new version. Apart from a few fixes / extensions already mentioned here (or known to those who wanted it) the main changes are in the math goodie files (work in progress, we will clean them up later) as part of improving the rendering of math.

Lopsided circles
by Thangalin 19 Oct '22

19 Oct '22

Using 2022.09.11 20:44, there appears to be a problem with rendering some circular forms, such as: % SOT \startbuffer[circle] <svg> <path d="m39.423 19.847c0 10.815-8.7666 19.576-19.58 19.576-10.812 0-19.579-8.7611-19.579-19.576 0-10.815 8.7669-19.583 19.579-19.583 10.813 0 19.58 8.7676 19.58 19.583z" /> </svg> \stopbuffer \starttext \placefigure{}{\includesvgbuffer[circle][conversion=mp]} \stoptext % EOT In Inkscape, this renders as a full circle without any deformation.

Perceptrons
by Thangalin 17 Oct '22

17 Oct '22

Okay, they aren't _real_ perceptrons, but fancy parameterized trees connected on a hex grid, coded with MetaFun and Lua. Big version: https://pdfhost.io/v/piuN04dSq_perceptron If anyone is interested in the full source code, let me know. I couldn't get "angle" to work properly. Hans, your simplifications on the atantwo function also didn't work for all cases. There was a single edge case that didn't determine the correct angle. Don't know why. Cheers!
