Disproportion in initializing user counters
by Jaroslav Hajtmar 15 Jul '18

15 Jul '18

Hello ConTeXist. I encountered a disproportion in initializing user counters. Why initialization at the beginning of the source text does not work and what is the mechanism of how the user counters work. Thanx Jaroslav Hajtmar Here is a sample example: \definecounter[mycounter] \def\getmycounter{\incrementcounter[mycounter]\getnumber[mycounter]} \startbuffer[groups] \startxrow \startxcell \getmycounter\stopxcell \startxcell Content of column\stopxcell \stopxrow \stopbuffer \starttext %\setcounter[mycounter][0] % initializing at this point not working (the counter is 10 more than it should be). WHY? \startxtable \startxrow \startxcell Column 1\stopxcell \startxcell Column 2\stopxcell \stopxrow \setcounter[mycounter][0] % initializing at this point works fine \dorecurse{5}{\getbuffer[groups]} \stopxtable \stoptext

Unexpected <break/> in XML output
by Rik Kabel 14 Jul '18

14 Jul '18

List, <break/> elements are inserted before <margintext> elements in XML and xhtml output, and empty divs of class break in html output. If this is intended, is there a way to prevent it? If not intended, can it be fixed? Example code: \setupbackend [export=yes] \starttext \startparagraph Taa aaaaaaaaaaa aa aaaaaaaaa aaaaaa aaa aaaaaaaa aa aaaaaaaaaa aaaaaa. Taa aaaaaaaa aaaaa\inleft{>}, aaaaa aaaaaaaa aa aaaaa aaaa aa aaaa aaaaaaaaa aa aaaaaaa aaaaa aaaaaaaa aaaaaaaaaaa, \inright{<} aaaaaaaaa aaaaaa a aaaaaa, aaaaaaaa aaa aaaaaaaaaa aaa aaaaa aaaa. \stopparagraph \stoptext XML output excerpt: <paragraph>Taa aaaaaaaaaaa aa aaaaaaaaa aaaaaa aaa aaaaaaaa aa aaaaaaaaaa aaaaaa. Taa <break/> <margintext detail="inleft" chain="inleft">></margintext>aaaaaaaa aaaaa, aaaaa aaaaaaaa aa aaaaa aaaa aa aaaa aaaaaaaaa aa aaaaaaa aaaaa <break/> <margintext detail="inright" chain="inright"><</margintext>aaaaaaaa aaaaaaaaaaa, aaaaaaaaa aaaaaa a aaaaaa, aaaaaaaa aaa aaaaaaaaaa aaa aaaaa aaaa.</paragraph> -- Rik

Figure captions: "Fig." instead "Figure"
by Procházka Lukáš Ing. 13 Jul '18

13 Jul '18

Hello, what is the way to change caption text for figures to be "Fig." instead of "Figure"? \setupcaptions[numberstopper={.},] changes "Figure 1" to "Figure 1.", but is there a similar key for the text? (\setupcations[prefix=] allows only "yes" or "no" - http://wiki.contextgarden.net/Command/setupcaptions ) Best regards, Lukas -- Ing.

Shading and transparency
by Marco Patzer 12 Jul '18

12 Jul '18

Hi! It's shadings and transparency again. For most things transparency is not required since the background colour (white) can be used instead, to achieve the same effect (thanks Hans for the reimplementation/cleanup a while ago). For one use case I worked around this by including an external file and overlay the external file (see attached example). Background: In the actual documents the transparent overlays overlay images to have the edges fade into the page background (only the centre is of interest). Is there a method that does not require an external file or pre-processing? Using the external file works. Just wondering if there's a better - more integrated - way. Marco

newest beta: luatex-fonts-merged.lua missing
by Ulrike Fischer 12 Jul '18

12 Jul '18

In the newest beta from 10. july luatex-fonts-merged.lua is missing in the generic fontloader folder. I tried to create it with the command mentioned in luatex-fonts-lua mtxrun --script package --merge --stripcontext luatex-fonts.lua But I got an error: ...xt/tex/texmf-context/scripts/context/lua/mtx-package.lua:80: attempt to perform arithmetic on global 'striped' (a nil value) Removing the -stripcontext worked: mtxrun --script package --merge luatex-fonts.lua -- Ulrike Fischer http://www.troubleshooting-tex.de/

loading hyphenation patterns (again)
by Pablo Rodriguez 10 Jul '18

10 Jul '18

Dear list, sorry for bothering with this again: \setuplanguage[agr][patterns={agr, en}] \setuplanguage[en][patterns={en, agr}] \starttext \hyphenatedword{judgmental} \agr\hyphenatedword{judgmental} \stoptext I wonder why English cannot have extra hyphenation patterns, while ancient Greek allows them. Have I hit a bug or am I missing something? Sorry for insisting, but I get weird results with column balancing (registers). Many thanks for your help, Pablo -- http://www.ousia.tk

text in mathematics
by Alan Braslau 10 Jul '18

10 Jul '18

Hello ConTeXt users, Does it drive you crazy to see TeX users write $t = time$? (I see this all of the time by LaTeX users in Beamer presentations.) One can do better writing $t = {\rm time}$ (maybe) or in ConTeXt $t = \mathrm{time}$. Sometimes, too, I might write $t = \text{time}$. We also have the commands \mathematics{} that can be used in place of the TeX shorthand $...$, and this also has the shortcut \m{...}. I thought that it might be useful to have an equivalent escape, to be used as $t = \t{time}$. What do other users think? OK, \m{t = \t{time}} might be a bit funky... Alan P.S. I proposed doing this via \let\t\mathrm but Hans tells me that this is not good, as \mathrm{} does not give proper font processing, so implementation of \t{} would be something different...
