Problem with Hello-World.tex
by Alessandro Perucchi 14 Jun '20

14 Jun '20

Hello everyone, I am quite new to ConTEXt, and after installed it according to the following web page : https://wiki.contextgarden.net/Installation <https://wiki.contextgarden.net/Installation> I’ve installed it in macOS Catalina 10.15.5. After a successful installation (I hope), I tried to run the “First Run!” part, so I’ve downloaded the file Hello-World.tex file (via wget), and I’ve run the command “context Hello-World.tex”. I’ve attached the resulting PDF, and it looks great, except for one part, which is the figure and the text flowing around it, which is not the case here. Is there something wrong in what I’ve done? I mean, I’ve done a fresh installation, download of Hello-World.tex and run the context command. Here are the version that I could find: ➜ ~ context --version mtx-context | ConTeXt Process Management 1.03 mtx-context | mtx-context | main context file: /Users/lg/Context/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2020.06.12 17:43 mtx-context | main context file: /Users/lg/Context/tex/texmf-context/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2020.06.12 17:43 Thank you! Regards, Alessandro

Wrong page numbers in frontmatter
by Jack Steyn 14 Jun '20

14 Jun '20

Hi, I'm not sure why the following MWE produces a document where page 2 has the page number i instead of ii. It seems to have something to do with the use of makeup. I was using it to create a vertically centered title page. Is there a better way of doing this which will give the correct page numbers? Best, Jack \definestructureconversionset[frontpart:pagenumber][][romannumerals] \definestructureconversionset[bodypart:pagenumber][][numbers] \definemakeup[titlepage][align=middle] \starttext \startfrontmatter \startmakeup[titlepage] Title \stopmakeup test \stopfrontmatter \startbodymatter \setcounter[userpage][1] test \stopbodymatter \stoptext

\the\font in luametatex
by Marcel Fabian Krüger 13 Jun '20

13 Jun '20

Hi, in the latest luametatex version, \the\font does ... something weird: E.g. with a current, fully updated lmtx, I get for \starttext \showthe\font \stoptext the output > }\ifempty \currentstyleparameter \else \dousecurrentstyleparameter \fi instead of the expected > \3>modern-designsize-12pt-rm-tf-0--0 (or similar) (given that this contains an unmatched `}`, it causes havoc if \the\font is used in unsuspecting macro code.) Best regards, Marcel

Asymptote and lmtx
by Otared Kavian 13 Jun '20

13 Jun '20

Hi all, Recently I have been using (in a very elementary way) Metafun in order to visualize a small set of data in 2 dimensions, as a scattered set of labeled dots, and I wanted to do the same in 3 dimensions. Indeed one can write an analogous Metafun code for 3d, but I thought using Asymptote is more efficient. I saw that there is a module m-asymptote.mkiv in the distribution, but typesetting that file with lmtx or mkiv does not give the expected result. Has anyone a working example of using Asymptote from within ConTeXt, from which I could begin to learn? Thanks for any hint: Otared

Extra space when \setcharacterkerning is used in enumeration
by Mikael Sundqvist 12 Jun '20

12 Jun '20

Hi, I noticed an extra space in an enumeration when using \setcharacterkerning in the \headstyle parameter. The extra space appears before the first word "Sats", and in my case it is unwanted (In the example I want the word Sats to align with a), b), ...). The space was not there a year ago, with the same code. In the test file below (sorry for its length), the environment sats is having the problem, while SATS does not. The only difference is in the \headstyle parameter. Am I missing something obvious? /Mikael PS I use the version of today, where the curious problems with sizes inside square roots and fractions seem to be gone. %%%%%%%%% Testfile starts here \setupbodyfont[stixtwo,10bp] \definemeasure[myitemwidth][26bp] \definemeasure[myindent][12bp] \setupindenting[yes,\measure{myindent}] \definecharacterkerning[sats][factor=0.1] \define[1]\vakuum{\hskip\measure{myindent}#1.} \defineenumeration[sats][ text={Sats}, style={\em}, title=yes, titlestyle=, width=fit, headstyle={\smallcaps\setcharacterkerning[sats]}, headcommand={\vakuum}, number=yes, alternative=serried, indenting={yes,\measure{myindent}}, ] \defineenumeration[SATS][sats][ headstyle=\smallcaps,%It is this setting that kills the space. ] \defineitemgroup[delab] \setupitemgroup[delab][each][a,intro,intext][ stopper=, right=), left={\hskip\measure{myindent}}, width=\measure{myitemwidth}, inbetween=, before={\blank[none,samepage]}, after=, style={\tf}, ] \starttext \startTEXpage[offset=3bp] \samplefile{ward} \startsats[title={Räkneregler för gränsvärden}] Antag att $c$ är ett tal, och att $a_k\to A$ och $b_k\to B$ då $k\to+\infty$.

Changed behavior of ^^ in csname
by Marcel Fabian Krüger 12 Jun '20

12 Jun '20

Hi, I noticed that in the latest LMTX version, ^^ (with ^ of catcode 7) is no longer interpreted inside csnames. Is this intentional? (Example: \starttext \catcode\circumflexasciicode=\superscriptcatcode% Ensure correct catcodes \show ^^41 % This still works and shows "> the letter A" \show^^41 % This used to be an error "Undefined control sequence \showA", % now show "> The letter A" \show\^^41 % Used to show "> \A=undefined", now shows "> \^=macro:->\enco_handle_accent {^}" % and "! Missing $ inserted" \stoptext ) Best regards, Marcel

More funny numbers
by Jairo A. del Rio 12 Jun '20

12 Jun '20

Hi everyone! The following example shows that numerators of fractions inside math alignment environments appear with a funny size: \startTEXpage \startformula \startmathalignment[n=1,align=middle] \NC \frac{1351}{780}>\sqrt{3}>\frac{265}{153}, 3013 \frac{3}{4}>\sqrt{9082321}, \quad 1838 \frac{9}{17}>\sqrt{3380929} \NR \NC 1009 \frac{1}{6}>\sqrt{1018405}, \quad 2017 \frac{1}{4}>\sqrt{4069284} \frac{1}{38}, \quad 591 \frac{1}{8}<\sqrt{349450} \NR \NC 1172 \frac{1}{8}<\sqrt{1373943\frac{84}{33}}, 2339 \frac{1}{4}<\sqrt{5472132 \frac{1}{16}} \NR \stopmathalignment \stopformula \stopTEXpage It's actually nice to find those bugs when one makes heavy use of math environments. For comparison, LuaTeX prints the correct output. Jairo :)

Draft Watermark of Garden gives unexpected results
by Jairo A. del Rio 11 Jun '20

11 Jun '20

The following example of using layers doesn't works as expected in ConTeXt https://wiki.contextgarden.net/Draft_Watermark The watermark is partially outside the page, whereas the Wiki result is more "centered". Is that an intended behaviour? Additionally, how to center an element in a layer with respect to the current page? Cordially, Jairo :)
