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. The roots may be equal or unequal, real or imaginary, according to circumstances. \stoptext

Double sided pages leave a thin white line on the right side

Hi, I was using \setuppagenumbering[alternative=doublesided] to get double sided pages. After doing that I noticed a thin white line on the right side.

Mono font goes inside right inline image
by Mia Bikey 28 Oct '23

Hi, I was using mono font as my default font but it appears to have issues with right side inline images. Here is a Minimal Working Example: ConTeXt ver: 2023.09.26 18:19 LMTX \setupbodyfont[mono] \starttext Image on the right side gets issues. \placefigure[right]{}{\externalfigure[dummy]} \input tufte \\ Image on the left side is fine. \placefigure[left]{}{\externalfigure[dummy]} \input tufte \stoptext

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

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. In mine it's python3 \defineexternalfilter [pythontyping] [filtercommand={python3 \externalfilterinputfile \space > \externalfilteroutputfile}, output={\externalfilterbasefile.tex}, cache=yes, readcommand=\typefile, spacebefore=medium, spaceafter=medium] %We copy settings to save typing \defineexternalfilter[pythonformula][pythontyping] %But instead of typing, we input a formula \setupexternalfilter[pythonformula] [readcommand=\samplefile] %\input should also work \starttext Convert angle to radians: $\startpythonformula from sympy import * print(latex(pi/180*60)) \stoppythonformula$ Compute trigonometric function: $\startpythonformula from sympy import * print(latex(cos(pi/3))) \stoppythonformula$ \stoptext However, I haven’t managed so far to combine things (lua and Python) in an automatic way. How should I proceed? A. Christe

Footnotes on the bottom of the column's current page, instead of the columns' end
by Juliano David Hilario 26 Oct '23

26 Oct '23

> > > Hello, I'm trying to achieve a look similar to a magazine our religious organization frequently discusses, but unfortunately can't find the correct settings to do so. Whenever I call a custom note on a column, instead of the note showing on the bottom of the page, it shows at the end of the column. (like an endnote, except, it shows as a small footnote at the beginning) How should I make it shown on the bottom of the page of the current footnote instead of the end of the column command?

sidebar and marginrule not working
by Hamid,Idris 24 Oct '23

24 Oct '23

Dear gang, The appears to be something wrong with the sidebar and marginrule mechanisms. MWE: ============== % ConTeXt ver: 2023.09.26 18:19 LMTX \setupmarginrule[1][rulecolor=darkred] \definesidebar[Sidebar][rulethickness=0.28pt,distance=3pt,rulecolor=darkgreen] \setupsidebar[rulecolor=darkgreen] \starttext \startmarginrule[1] \input ward \stopmarginrule \blank \startsidebar[Sidebar] \input zapf \stopsidebar \stoptext ============== In the output, either i) the rules do not appear at all (most attempts); or ii) the rules appear for a split-second then disappear (using sumatrapdf as the viewer, so the pdf updates on the fly). Is is a bug? A second question: Is either mechanism preferable over the other? That is: In LMTX, what is the best mechanism to use? Thank you in advance for any guidance.

Large unwanted white space
