Several math features broke for me in new Debian version
by Kumar Appaiah 03 Nov '23

03 Nov '23

Dear Friends, I am a regular user of ConTeXt. A recent upgrade of ConTeXt in Debian broke things for me. The bug report is here: https://bugs.debian.org/1055233 but I have reproduced the gist here: Upon upgrading to ConTeXt 2023.05.05.20230730+dfsg-2, several math features seem to break for me. Here is an example: \starttext Hello world! \startformula X(f) = \startcases[align={right,left},distance=3pt] \NC T, \NC{} $|f| < \frac{1}{2T}$ \NR \NC 0, \NC{} $|f| \geq \frac{1}{2T}$ \NR \stopcases \stopformula \stoptext The above works very well in 2021.03.05.20230120+dfsg-1+deb12u1 but gives me this error in 2023.05.05.20230730+dfsg-2: resolvers | formats | executing runner 'run luametatex format': /usr/bin/luametatex --jobname="./test.tex" --socket --shell-escape --fmt=/home/kumar/.texlive2023/texmf-var/luametatex-cache/context/f919750633122078d706dd10f1cfd39b/formats/luametatex/cont-en.fmt --lua=/home/kumar/.texlive2023/texmf-var/luametatex-cache/context/f919750633122078d706dd10f1cfd39b/formats/luametatex/cont-en.lui --c:currentrun=1 --c:fulljobname="./test.tex" --c:input="./test.tex" --c:kindofrun=1 --c:maxnofruns=9 --c:texmfbinpath="/usr/bin" job > passes > version mismatch: 1.32 <> 1.33 system > system > ConTeXt ver: 2023.05.05 18:36 LMTX fmt: 2023.11.2 int: english/english system > system > 'cont-new.mkxl' loaded open source > level 1, order 1, name '/usr/share/texmf/tex/context/base/mkxl/cont-new.mkxl' system > beware: some patches loaded from cont-new.mkiv close source > level 1, order 1, name '/usr/share/texmf/tex/context/base/mkxl/cont-new.mkxl' system > files > jobname './test', input './test.tex', result './test' fonts > latin modern fonts are not preloaded languages > language 'en' is active open source > level 1, order 2, name './test.tex' fonts > preloading latin modern fonts (second stage) mathematics > tweak > 'LatinModernMath-Regular', size 6, math size 3, version 'Version 1.959' found, version 'Version 1.958' expected fonts > 'fallback modern rm 12pt' is loaded tex error > tex error on line 5 in file ./test.tex: Missing $ inserted <inserted text> $ <to be read again> \mathatom <macro> \math_atom_by_parameter_indeed #1->\mathatom \s!class \mathcodechecked {#1} <macro> \math_frac #1#*[#2]->\beginmathgroup \setlocalmathfractioncurrent {#1}\ifparameter #2\or \setupcurrentmathfraction [#2]\fi \edef \p_math_fraction_fences {\mathfractionparameter \c!fences }\math_atom_by_parameter \mathfractionparameter \bgroup \ifempty \p_math_f <to be read again> { <line 3.5> \NC T, \NC{} $|f| < \frac{ 1}{2T}$ \NR 1 \starttext 2 Hello world! 3 \startformula 4 X(f) = \startcases[align={right,left},distance=3pt] 5 >> \NC T, \NC{} $|f| < \frac{1}{2T}$ \NR 6 \NC 0, \NC{} $|f| \geq \frac{1}{2T}$ \NR 7 \stopcases 8 \stopformula 9 \stoptext 10 I've inserted a begin-math/end-math symbol since I think you left one out.

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

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.

Combining python and lua
by Alexandre Christe 26 Oct '23

26 Oct '23

Dear list, I’d like to know the best approach to make this a bit more usable. I’m trying to typeset a table with sin/cos/tan values. I’d like to be able to convert the angles in degrees into radians (with math notation) and to compute the trigonometric function leading to sin(pi/4) = 1/2, or cos(pi/6) = sqrt(3)/2 and display it in math mode. Here’s my current MWE, where I fail to convert the angles in radians and fail to display the result in symbolic form. \starttext \startluacode local angleList = {0, 30, 45, 60, 90, 120, 135, 150, 180, 210, 225, 240, 270, 300, 315, 330, 360} context.bTABLE() context.bTR() context.bTD() context("$x$") context.eTD() context.bTD() context("$0$") context.eTD() for _, a in ipairs(angleList) do context.bTD() context("$\letterpercent.0f$",a) context.eTD() end context.eTR() context.bTR() context.bTD() context("$\\cos(x)$") context.eTD() for _, a in ipairs(angleList) do context.bTD() context("$\letterpercent.3f$",math.cos(math.rad(a))) context.eTD() end context.eTR() context.bTR() context.bTD() context("$\\sin(x)$") context.eTD() for _, a in ipairs(angleList) do context.bTD() context("$\letterpercent.3f$",math.sin(math.rad(a))) context.eTD() end context.eTR() context.bTR() context.bTD() context("$\\tan(x)$") context.eTD() for _, a in ipairs(angleList) do if a == 90 or a == 270 then context.bTD() context("$-$") context.eTD() else context.bTD() context("$\letterpercent.3f$",math.tan(math.rad(a))) context.eTD() end end context.eTR() context.eTABLE() \stopluacode \stoptext \stoptext One possible way would be to use Python and the t-filter module, like this \usemodule[filter] %It depends on your OS.

overprinting black
by Henning Hraban Ramm 21 Oct '23

21 Oct '23

Hi, esp. Hans, while finalizing the PDF for our latest book, I recognized a color problem: The general black color is rendered not 100% black in CMYK mode, but in all channels (converted RGB, I guess). With \definecolor[cmykblack][k=1] \setupcolors[textcolor=cmykblack] this is ok, but the color mode is knockout instead of overprint (as it would be usual for CMYK black). That means, black text on a photo is white in the other plates. If I define \definecolor[cmykblack][k=1,a=multiply,t=1] \setupcolors[textcolor=cmykblack] it’s ok in some places, but it messes up many unrelated places, e.g. most images then also use this transparency mode. \setupcolors[intent=overprint] has no effect, as far as could find (while we have a warning in the wiki, that you should use this only for grayscale works). What can I do? Hraban

Testing whether an XML attribute exists
by Michael Guravage 17 Oct '23

17 Oct '23

Hi, I am typesetting a very simple address list whose source is written in XML. Typesetting choices need to be made dependent on the presence of various attributes; consider the following <family> element. <family surname="Boer" prefix="den"> If the prefix attribute exists I'l like the name to appear as, e.g. 'Boer, den." The several XML attribute testing functions in the XML manual appear to discriminate on an attribute's value. I tried \xmldoifnotatt in an attempt to say, "TRUE if prefix does not match an empty string", since I am not interested in the attribute's value but only whether or not it exists. The code below doesn't work. If someone who knows why it doesn't work would enlighten my ignorance I would be most grateful. A brief explanation and example of \xmldoifatt, \xmldoifnotatt, and \xmldoifelseatt would be exceedingly helpful. \startxmlsetups xml:list:family {\bf \xmlatt{#1}{surname} \xmldoifnotatt{#1, prefix, ''} {, \xmlatt{#1}{prefix}}} \crlf \xmlflush{#1} \stopxmlsetups I have attached three files below: an XML address list, the ConTeXt source file and the typeset result. -- With kind regards, Michael Guravage

colors for links
by Pablo Rodriguez 14 Oct '23

14 Oct '23

Hi Hans, I have the following source, which tries to resemble three kinds of links: \setupinteraction[state=start, style=, focus=standard] \def\inone#1{% \start\setupinteraction[color=darkgreen]% \enabledirectives[references.border=darkgreen]% \goto{#1}[url(#1)]\stop} \def\intwo#1{% \start\setupinteraction[color=darkred]% \enabledirectives[references.border=darkred]% \goto{#1}[url(#1)]\stop} \def\inthree#1{% \start\setupinteraction[color=darkblue]% \enabledirectives[references.border=darkblue]% \goto{#1}[url(#1)]\stop} \starttext \startTEXpage[offset=1dk, align=middle] \inone{one}\blank \intwo{two}\blank \inthree{three}\blank \stopTEXpage \chapter[one]{First chapter} \chapter[two]{Second chapter} \chapter[three]{Second chapter} \stoptext I see that the directive for link borders only allows one color for links per document. In my real-world documents, I need to make three different border links: for destinations inside the document (/GoTo), for destinations in other documents (/GoToR or /GoToE) and for external destinations (/URI). With the current document I write now, I have over a hundred links in twenty pages. Being able to visually distinguish each link helps interaction with the document (reading or even writing it). Would it be possible that \setupinteraction could have a bordercolor key, such as the color one? Many thanks for your help, Pablo

Hi, I would like to obtain, if possible, a gray gradient like in the image. My code uses Metapost but maybe this is possible with Metafun. Thanks.

How can I use a variable for a MetaPost coordinate ?
by peter.hopcroft＠icloud.com 06 Oct '23

06 Oct '23

Hello list, I want to draw lines on a page. I want to pass my line coordinates as a percent of \width or \textheight, rather than as millimetres. So that if I change the page size I don't need to change the coordinates. The MWE below compiles but the pdf does not have any lines drawn on it. Is there a way of doing calculations on the coordinates for the draw using ConTexT variables like \textheight? Thank you, Peter Hopcroft ------ \starttext Some text \startMPcode pickup pensquare scaled 1pt; draw (0mm,0mm)--(0mm,\textheight) withcolor red \stopMPcode More text \startMPcode pickup pensquare scaled 1pt; draw (0mm,0mm)--(0mm,50mm) scaled \numexpr\textheight/50mm\relax \stopMPcode \stoptext ------

Following the instructions on https://wiki.contextgarden.net/PDF/A, I am receiving errors that the *.icc files cannot be located.
