Status of Asymptote
by Alexandre Christe 11 Jan '24

11 Jan '24

Dear all, I'd like to know what is the status of Asymptote in Context. To my knowledge, metapost/metafun only support 2D (except with the additional libraries from Roegel, which would have to be cleaned up a bit). Otherwise, what shall be used for 3D drawings in Context? TikZ? Something else? Thanks in advance. Alex

typearea

Hi, I'm new to ConTeXt and try to use the module typearea (https://modules.contextgarden.net/cgi-bin/module.cgi/action=find/name=typea…). But the example doesn't work: \usemodule[typearea] \setupTypeArea[bcor=0mm,alphabets=3.1] \setuppagenumbering[alternative=doublesided] \starttext \dorecurse4{\framed[width=\textwidth,height=\textheight]{test}\page} \stoptext I got: texmf-dist/tex/context/third/typearea/t-typearea.tex' loading > Something like KOMA-TypeArea tex error > tex error on line 89 in file /usr/local/texlive/2023/texmf-dist/tex/context/third/typearea/t-typearea.tex: Missing number, treated as zero <to be read again> { <macro> \TA@alphabets \par \PageWidth =\dimexpr \paperwidth -\TA@bcor \relax \par \edef \Ratio {\withoutpt { \the \dimexpr 2\paperheight /(\PageWidth /32768)\relax }} \par \setbox \scratchbox \hbox {\dorecurse {26}{\character \recurselevel }} \Width =\dimexpr \TA@alphabet <line 5.89> \setupTypeArea[bcor=0pt,oneside=no,alphabets=2.6] 79 height=\the\Height, 80 width=\the\Width, 81 header=2\lineheight, 82 headerdistance=\lineheight, 83 footer=2\lineheight, 84 footerdistance=3\lineheight, 85 topspace=\Top] 86 } 87 \protect 88 89 >> \setupTypeArea[bcor=0pt,oneside=no,alphabets=2.6] 90 91 \doifnotmode{demo}{\endinput} 92 93 %D Usage example: 94 \usemodule[typearea] 95 \setupTypeArea[bcor=0mm,alphabets=3.1] 96 \setuppagenumbering[alternative=doublesided] 97 \starttext 98 \dorecurse4{\framed[width=\textwidth,height=\textheight]{test}\page} 99 \stoptext A number should have been here; I inserted '0'. (If you can't figure out why I needed to see a number, look up 'weird error' in the index to The TeXbook.) mtx-context | fatal error: return code: 1 Line 89 in the module should be the problem. But how can I solve it? I think some lines in the module should be commented out. (An example directly in the module?) I thank you for any hint. Greetings Thomas

Adobe Source Typescript With Design Sizes
by Vincent Hennebert 03 Nov '23

03 Nov '23

Hello there, I had mentioned this on a thread some (long) time ago, finally got around to finishing a first version of a typescript with the Adobe Source font family, in all its weight alternatives and design sizes (the latter being available in the Serif style only). Comments welcome. If it looks good I can upload it to the wiki, on the Typescripts_examples page I guess. (I have Questions For the Experts further down...) About Adobe Source ================== The fonts are available on GitHub [1]. They are the descendants of the Source {Serif,Sans,Code} Pro fonts described in the type-imp-source.mkiv typescript available in the ConTeXt distribution. Due to major changes, Serif Pro was renamed into Serif 4 in, well, its version 4 [2] (that’s the version that introduces design sizes, a.k.a. optical sizes), and Sans Pro was renamed into Sans 3 [3]. [1] https://github.com/adobe-fonts/ [2] https://github.com/adobe-fonts/source-serif/releases/tag/4.004R [3] https://github.com/adobe-fonts/source-sans/issues/192 Usage ===== Short version: store the attached typescript and its helper Lua files somewhere on your file system where ConTeXt will find them ($HOME/texmf for example), then use in your document: \setupbodyfont[adobesource] Long version: The default typescript name is adobesource (also available as adobesource-regular) and has design sizes enabled. Each weight is also available: adobesource-extralight, adobesource-light, etc., all the way to adobesource-black. There is also a medium weight, that selects the regular versions of Serif and Sans, but the medium version of Mono (just slightly bolder than the regular one, presumably for better on-screen rendering in terminals). Design sizes can be disabled by adding -nodesignsize- to the typescript name: adobesource-nodesignsize-extralight, etc. Finally, I thought it would be cool to over-engineer the typescript a little bit and provide direct access to the design sizes (in case one would want a narrower version for body text, or a bolder and more expanded version for titles, etc.). Here they are, again in all their weights: adobesource-caption-extralight, adobesource-smtext-light, adobesource-subhead, adobesource-display-bold, etc. The ‘regular’ design size is accessed by simply using adobesource-nodesignsize. Questions For the Experts ========================= To avoid a gigantic typescript file with a lot of duplication, I offloaded the font filename calculation to a Lua function (see attached adobesource.lua). I initially wanted to put the Lua code inside the typescript, but then I had all sorts of weird Lua compilation errors. The very same code works fine when included in a normal document though. Could it be that typescripts are processed in some special mode that doesn’t like Lua syntax? As a workaround, I put the code in an external file and require it from inside the typescript. In the goodies file, I use what I believe is the largest possible font size that can be used in ConTeXt (16,383pt) to select the Display design size. Otherwise, text above that size will fall back to the default, regular design size. Now, since I use the goodies file only when design sizes are enabled, I thought I could make it more robust by using AdobeSource4Display as a default, that is, for any size above 16.5pt. However, if I mix design sizes enabled and disabled in a document, the disabled one seems to be using the goodies file even though it’s not mentioned in the typescript. Any idea of why? For example: \usetypescriptfile[adobesource] \usebodyfont[adobesource] \setupbodyfont[adobesource-nodesignsize] \starttext This text is typeset in Display when Regular should be used. \switchtobodyfont[adobesource] This text is typeset in Regular with design sizes enabled. \stoptext What’s Next =========== * A harmonious-looking companion math font. * A harmonious-looking companion math font that uses glyphs from Adobe Serif 4 when available. Thanks, Vincent

In that case you have to go for flushleft \setupalign[verytolerant,nothyphenated,flushleft] because otherwise tex will try to come to the best solution by using stretch and shrink and therefore stretch and shrink in interatom spacing wins over little or none in mono spacing Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Inline mathematics is stretched
by Mia Bikey 29 Oct '23

29 Oct '23

Hi, I was using \setupalign[verytolerant,stretch] so that the mono font does not go inside the right inline image but after using that command the inline math seems to spread. Here is a Minimal Working Example: ConTeXt ver: 2023.09.26 18:19 LMTX \setupbodyfont[10pt, mono] This is how it should look. \\ When $a, b, c$ are given, two values of $x$ and no more can be found which shall make the function $ax^2 + bx + c$ vanish; that is, the equation always has two roots and no more. The roots may be equal or unequal, real or imaginary, according to circumstances. \\ \starttext \setupalign[stretch] This paragraph seems to look fine on 12pt. \\ When $a, b, c$ are given, two values of $x$ and no more can be found which shall make the function $ax^2 + bx + c$ vanish; that is, the equation always has two roots and no more. The roots may be equal or unequal, real or imaginary, according to circumstances. \\ \setupalign[verytolerant, nothyphenated] It looks even worse when I also use verytolerant and nothyphenated. \\ When $a, b, c$ are given, two values of $x$ and no more can be found which shall make the function $ax^2 + bx + c$ vanish; that is, the equation always has two roots and no more.

Hi, I was using mono font as my default font but it appears to have issues with right side inline images.

Color option in \setupinteraction doesn't work sometimes
by Mia Bikey 28 Oct '23

28 Oct '23

Hi, I was trying to get all my references black as it goes well along with black text but they appear red in some pages. I have reinstalled context in case there was some software issue but it is still the same. Here is a minimal working example: ConTeXt ver: 2023.09.26 18:19 LMTX \setupinteraction[state=start, color=black] \starttext \placeformula[eq:equation1] \startformula x \stopformula References are red on the first page \in[eq:equation1] \at{page}[eq:equation1] \input tufte \input tufte \input tufte \input tufte \input tufte Now they become black \in[eq:equation1] \at{page}[eq:equation1] \stoptext
