How to set the vertical spacing between a sequence of images?
by Joel 25 Oct '22

25 Oct '22

I have code like this which randomly pulls a page from `comic2.pdf` and displays it, scaled to fit \textwidth, then displays four more random pages afterwares. \starttext \dorecurse{5}{ \placefigure[force, none]{}{\framed[frame=off]{\externalfigure[comic2.pdf][page=\randomnumber{1}{34}, width=\textwidth]}} }\stoptext The problem is I need to adjust the vertical space between the images. It seems to be set to some lineheight or such, but I need the distance between each image to be at 1/50th or 0.02 of \textwidth. ...though the last image can have the ordinary gap afterwards. How can I se the vertical spacing between this sequence of image to 0.02\textwidth? --Joel

Hyphenation in multi-language projects
by Steffen Wolfrum 24 Oct '22

24 Oct '22

Hi, please have a look at this minimal example. The idea is to set the hyphenation for certain words regardless of the language that is used in the surrounding paragraphs. In this example it should stay: «steff-en» How do i set this to all non-english paragraphs (without using \hyphenation on each language-switch)? Best, Steffen — \starttext \setuppapersize[A6][A6] \mainlanguage[en] \startexceptions steff-en \stopexceptions english text english text english teste: steffen \start\language[it] italian text italian text italian teste: steffen \stop \start\language[it]\hyphenation{steff-en} italian text italian text italian teste: steffen \stop \stoptext

Backgrounds has changed in latest lmtx
by Thomas A. Schmitz 23 Oct '22

23 Oct '22

Hi everybody, With the latest lmtx, my page backgrounds don’t work any more. I think Otared mentioned that the simpleslides module is having problems. I’m trying to figure out what is happening, but I don’t see any warnings or errors, just unexpected results (which is not a good thing). I’m starting with the fundamentals. Here is a fairly minimal example: compile with context --luatex to see the expected result and with lmtx to see what is wrong. All best Thomas \setuppapersize[A6,landscape][A6,landscape] \setuplayout[backspace=1cm, topspace=0.4cm, marking=off, width=13cm, height=9.7cm, header=0.6cm, footer=0cm, ] \startreusableMPgraphic{card} StartPage ; save p ; path p[] ; p[0] = ulcorner Page -- urcorner Page ; p[0] := p[0] shifted (0, -0.97cm) ; for i = 1 upto 18 : p[i] = p[i-1] shifted (0, -14.42pt) ; draw p[i] withcolor (0.5,0.5,0.5) ; endfor ; pickup pencircle scaled 2pt ; draw p[0] withcolor red ; StopPage ; \stopreusableMPgraphic \defineoverlay[Card][\reuseMPgraphic{card}] \setupbackgrounds[page] [state=repeat, background={Card}] \starttext Test \stoptext

issue with variable font
by Pablo Rodriguez 23 Oct '22

23 Oct '22

Dear list, I have the following sample (using current latest from 22022.10.22 11:23): \definefontfeature [book] [axis={weight=700}] \definefontfamily[mainface][rm] [Commissioner][features={default, book}] \setupbodyfont[mainface, 25pt] \starttext \startTEXpage[offset=1ex, align=center] EFT ΕΘΞ \blank[quarterline] \dontleavehmode \externalfigure[commissioner][width=.25\textwidth] \stopTEXpage \stoptext The external figure is the output from Inkscape 1.1.2. I attach the generated PDF document from the source above. The variable font from Commissioner can be downloaded from https://github.com/kosbarts/Commissioner/releases/download/1.000/Commission…. ConTeXt seems to misread the font strokes (paths [or whatever the right name might be]), since Inkscape has no problems with it. Could anyone be so kind to confirm the issue? Many thanks for your help, Pablo

Formula has excess vertical spacing when in two column itemize
by Gavin 22 Oct '22

22 Oct '22

Hi List, I am getting better at adjusting the space in enumerations, but I just put a formula inside an enumeration, and the formula’s vertical spacing became excessive. I’m not sure how the enumeration caused this problem. \starttext Evaluate the following derivatives. \startitemize[n, columns, two, nowhite, after] \item\hspace[big] $\frac{d}{dx} x^2$ This is where the solution should be. Text answers look fine, but formulas have too much space above, below and between lines\dots. \item\hspace[big] $\frac{d}{dx}\left( x^3 + 2x \right)$ \item\hspace[big] $\frac{d}{dx}\left( x^{-2} \right)$ \item\hspace[big] $\frac{d}{dt}\left( 4t^4 - 3t^{\onehalf} \right) $ \item\hspace[big] $\frac{d}{dt}( 9 - 3t )$ \startformula\startmathalignment \NC \frac{d}{dt}( 9 - 3t ) \NC= \frac{d}{dt} 9 - \frac{d}{dt} 3t \NR \NC \NC= 0 - 3\frac{d}{dt} t \NR \NC \NC= -3\cdot 1t^0 \NR \NC \NC= -3 \NR \stopmathalignment\stopformula \item\hspace[big] $\frac{d}{dp}\left( p^3 - 2p \right)$ \stopitemize \stoptext I’m also attaching a file with the above issue followed by the correct spacing in one-column for comparison. I’m using LMTX (today’s upload, ver: 2022.10.21 21:13 LMTX fmt: 2022.10.21) on an M1 Mac. Any ideas? Gavin

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 21 Oct '22

21 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.
