how to interrupt doublesided in particular instance
by jbf 06 May '20

06 May '20

Hi list, I have a document set up in a standard way (\setuppagenumbering[alternative=doublesided]) to ensure that new chapters always begin on a recto page, but in one particular instance only, I want the new chapter to start on the next (verso) page instead of creating a blank then starting on the recto side. I thought I might have been able to force that with \page[no] immediately after the previous chapter concluded or before \chapter{My new chapter}, but this command is ignored (and may well be the wrong command to achieve what I want). Is there a way to interrupt the setup so the new chapter in this case can start on the verso page? Julian

conflict between colored emoji and save/restore
by Ulrike Fischer 06 May '20

06 May '20

When using a colored emoji font directly after a save/restore pair in context mkiv following text gets lost: \pdfvariable compresslevel=0 \font\fontB={file:seguiemj.ttf:mode=node;+colr;} \starttext \pdfextension save\relax \pdfextension restore\relax {\fontB \char"2603} xxxx %xxxx is not there \stoptext The problem is that the coordinate transformation from the restore ends inside the emoji code: /Span << /ActualText <feff2603> >> BDC q 0.000 g 1 0 0 1 -70.867 -714.33967 cm %<---- BT (Such an save/restore part is e.g. inserted with a scaled graphics: \externalfigure[tinypicture.pdf][width=1cm]) -- Ulrike Fischer http://www.troubleshooting-tex.de/

Thank you for answering. I have had looked into this source before and tried exactly the same approach you descrived but I am on TeXlive 2019 where this is defined differently: \unexpanded\def\registerpagerange#1#2#3#4#5#6#7#8% #1:class #2:processor content, content todo: -- configurable {\pushcurrentregister{#1}% \edef\p_pagenumber{\registerparameter\c!pagenumber}% \ifx\p_pagenumber\v!no\else \registerpageseparator \global\setconstant\c_strc_registers_page_state\plusone \dostarttagged\t!registerpagerange\empty \dostarttagged\t!registerfrompage\empty \withregisterpagecommand{#2}{#3}{#4}{#5}% \dostoptagged \registeronepagerangeseparator \dostarttagged\t!registertopage\empty \withregisterpagecommand{#2}{#6}{#7}{#8}% \dostoptagged \dostoptagged \fi \popcurrentregister} and, most importantly, does not work with this approach: \unexpanded\def\registerpagerange#1#2#3#4#5#6#7#8% #1:class #2:processor content, content todo: -- configurable { \pushcurrentregister{#1}% \edef\p_pagenumber{\registerparameter\c!pagenumber}% \ifx\p_pagenumber\v!no\else \registerpageseparator \global\setconstant\c_strc_registers_page_state\plusone \dostarttagged\t!registerpagerange\empty \dostarttagged\t!registerfrompage\empty \withregisterpagecommand{#2}{#3}{#4}{#5}% \dostoptagged \ifnum#3=\numexpr#6-1\relax f.% \else \registeronepagerangeseparator \dostarttagged\t!registertopage\empty \withregisterpagecommand{#2}{#6}{#7}{#8}% \fi \dostoptagged \dostoptagged \fi \popcurrentregister} May it be that parameters have changed since then?

ConTeXt version stuck at 2020.01.30
by Marco Patzer 05 May '20

05 May '20

Hi! Has something changed regarding the installation/update procedure? ConTeXt seems to be stuck at 2020.01.30 and downloading the newest version results in that very version. Steps to reproduce: rsync -ptv rsync://contextgarden.net/minimals/setup/first-setup.sh . sh ./first-setup.sh . tex/setuptex context --version → current version: 2020.01.30 14:13 According to https://minimals.contextgarden.net/current/context/ the directory “latest” seems to contain the latest version, rather than the “beta”. first-setup.sh however uses the “beta” directory. Has something changed and first-setup.sh hasn't been updated to reflect that change? Or is something else going on? Adapting first-setup.sh to mirror from the “latest” directory seems to fetch the latest version: rsync -ptv rsync://contextgarden.net/minimals/setup/first-setup.sh . sed -s '/\/bin\/mtxrun/s/--context=beta/--context=latest/' first-setup.sh sh ./first-setup.sh . tex/setuptex context --version → current version: 2020.04.30 11:10 Marco

Definition of \registerpagerange
by Hynek, Stefan 05 May '20

05 May '20

Hello fellow ConTeXies, since April 2019 it is possible to use \setupregister with compress=text which is a fine addition and has its use cases. Unfortunately, I am confronted with the demand to style the registers with 'f.' for a following single page and else with page ranges. Since the Definition of \registerpagerange is not well documented I don't know which parameter to check for the conditional statement when rewriting it. Could you please give me a hint? In ConTeXt that shipped with TeXlive 2015 it worked that way: \unexpanded\def\registerpagerange#1#2#3#4#5#6#7% {\registerpageseparator \global\setconstant\c_strc_registers_page_state\plusone \dostarttagged\t!registerpagerange\empty \dostarttagged\t!registerfrompage\empty \withregisterpagecommand{#1}{#2}{#3}{#4}% \dostoptagged \ifnum\the\numexpr#6-#3\relax=1 f.% \else \registeronepagerangeseparator \dostarttagged\t!registertopage\empty \withregisterpagecommand{#1}{#5}{#6}{#7}% \dostoptagged \fi \dostoptagged} With best regards Stefan

Shift tabulate into margin and center
by Tim Steenvoorden 05 May '20

05 May '20

Hi all, I’ve a page layout with a broad left margin. I’d like to create frames in the text which utilize the margin and the typearea with centered contents. I managed to do this with the following code, but I wonder if there is an easier and more elegant way to do this in ConTeXt, especially the centering of the tabulation. Cheers, Tim \startproduct test-tabulate \setuppapersize[B5] \setuplayout [backspace=13pc, leftmargin=8pc, leftmargindistance=1pc, width=24.5pc, rightmargin=0pc, %% topspace=4pc, header=0pc, height=49pc, footer=0pc, bottomdistance=2.5pc, bottom=1pc, location=middle] \define\fullwidth{\dimexpr(\leftmargindistance+\leftmarginwidth+\textwidth)} \section{First} \subsection{First first} \input tufte \setupnarrower[left=-9pc] \startnarrower[left] \startframedtext[frame=off,topframe=on,bottomframe=on,align=middle,width=\fullwidth] The whole frame should be shifted to the left. As the text, this table should centered in the box. \placefigure[none,force]{} \starttabulate[|l|r|] \NC 0 \NC 1 \NR \NC 2 \NC 3 \NR \NC 4 \NC 5 \NR \NC 6 \NC 7 \NR \NC 8 \NC 9 \NR \stoptabulate \startformula E=mc^2 \stopformula \stopframedtext \stopnarrower \input tufte \stopproduct

Re: [NTG-context] Vertical lines in matrices
by Jeong Dal 05 May '20

Dear Weber Mattias, Please see page 10 of “mathalign.pdf” made by Aditya. He showed the way of writing aligned math including matrices. For example, \startformula \startmatrix[left={\left(\,},right={\,\right)}] \NC 1 \NC 0 \NC 0 \NR \NC 0 \NC 1 \NC 0 \NR \NC 0 \NC 0 \NC 1 \NR \stopmatrix \stopformula There are many other examples that you can use.

How do I add cyrillic to my typescript/document?
by Gerben Wierda 05 May '20

05 May '20

I am looking for a way to amend a typescript for the additional use of cyrillic characters. I currently use: \starttypescript [sans] [optima] \setups[font:fallback:sans] \definefontsynonym [Sans] [file:Optima.ttc(Optima Regular)] [features=default] \definefontsynonym [SansBold] [file:Optima.ttc(Optima Bold)] [features=default] \definefontsynonym [SansItalic] [file:Optima.ttc(Optima Italic)] [features=default] \definefontsynonym [SansBoldItalic] [file:Optima.ttc(Optima Bold Italic)] [features=default] \stoptypescript \definetypeface [optima] [ss] [sans] [optima] [default] \definetypeface [optima] [rm] [serif] [optima] [default] \definetypeface [optima] [tt] [mono] [modern] [default] \definetypeface [optima] [mm] [math] [pagella] [default] \setupbodyfont [optima] But Optima doesn’t have cyrillic characters. So, either I have te use another typescript. I tried creating a Helvetica (as Helvetica.ttc on macOS seems to have cyrillic characters) but did not succeed. I also tried \language[ru] without any \setupbodyfont hoping it would also fix the font issue but keep getting fonts > checking > char –® (U+00428) in font 'LMRoman10-Regular' with id 8: missing I read the languages-mkiv document but it did not say what I had to do about fonts. What do I have to do to get both English and Russian in my document in terms of fonts? G

Changing the font size in an environment changes the behavior of a macro

Hi, This macro was written by Otared and it works well unless I change the size of the font (see the second graph). How to correct this problem ? Thanks for your help.

Three-deep itemize fails on LMTX
by Rik Kabel 04 May '20

04 May '20

List, The following example works with MkIV latest, but fails with LMTX latest (Win10 x64). The complaint is ! Missing math style, treated as \displaystyle. \starttext \startitemize \item Level 1 first \startitemize \item Level 2 first \startitemize \item Level 3 first \stopitemize \stopitemize \stopitemize \stoptext The culprit is the third level of itemize -- without that it is clean on both engines. I would appreciate knowing if other folks have the same problem, and if so, if there is a workaround until a fix can be posted. -- Rik
