lmtx
by Hans Hagen 19 Feb '21

19 Feb '21

Hi, In the last couple of lmtx uploads \startTEXpage should work a bit better. These uploads also introduced a new option for alignments, which can be checked in: \def\DemoA#1{\vbox{\red \hsize#1\input tufte }} \def\DemoB#1{\vbox{\green \setupalign[always]\hsize#1\input tufte }} \def\DemoC#1{\startTEXpage[offset=10pt]\DemoA{#1pt}\blank\DemoB{#1pt}\blank#1pt\stopTEXpage} \starttext \dostepwiserecurse{300}{600}{10}{ \startTEXpage[offset=10pt] \startoverlay {\DemoA{#1pt}} {\DemoB{#1pt}} \stopoverlay \blank \the\dimexpr#1pt\relax \stopTEXpage } \DemoC{370} \DemoC{390} \DemoC{490} \DemoC{540} \DemoC{580} \stoptext I leave it to users to determine if the few cases where the results differ are better or worse but one can for instance use it to influence (as side effect) the last line. In general, tweaking the machinery can give different results and i guess that hardly any user can make consistent claims about what is better. It all depends on what one deals with. (The keyword is suboptimal, it kind of tells what happens but on the other obscurew what really goes on: always forcing a first hyphenation pass when breaking lines.)

Are positional graphics still working?
by Jairo A. del Rio 17 Feb '21

17 Feb '21

I've copied the following example from the ConTeXt archive: \defineoverlay[frames][\positionoverlay{frames}] \setupbackgrounds[text][background=frames] \startMPpositiongraphic{frame} if unknown context_apos : input mp-apos.mpiv ; fi ; \MPgetposboxes{\MPvar{self}}{\MPanchorid} if nofposboxes = 1 : draw posboxes[1] ; fi ; \stopMPpositiongraphic \startpositionoverlay{frames} \setMPpositiongraphic{one}{frame} \setMPpositiongraphic{two}{frame} \stoppositionoverlay \starttext This \hpos{one}{word} should be \hpos{two}{framed}. \stoptext Frames are misplaced, so I don't know if that's a bug or something else has been updated/changed/deprecated. Thank you in advance. Jairo

infinite number of runs
by Pablo Rodriguez 17 Feb '21

17 Feb '21

Hans, I have some documents that trigger infinite runs. I want to provide a minimal sample that shows this. But is there some code in the .tuc file (or in the .log file with \tracingall) that shows the need of another run? Many thanks for your help, Pablo -- http://www.ousia.tk

set fallback in \definefont
by Mohammad Hossein Bateni 16 Feb '21

16 Feb '21

Hi, Is there a way to set the fallback for fonts when we define them not as a typescript but using \definefont? \definefont[MyFont][Font.otf*MyFeatures] Is there a default fallback one can specify? Is simplefonts module deprecated or discouraged now? When we define a font via typescript commands, we can specify rm, ss, tt, mm, hw and cg shapes for it. Can we add arbitrary styles? For example, I would use this for quotations, headings, etc. Currently, I either have to spare ss or use \definefont for such scenarios. Thanks, --MHB

temporary changes to the layout - \startlocal undefined
by Werner Hennrich 16 Feb '21

16 Feb '21

Hello Everybody, I need to increase my header's space temporarily and according to pg 99 of context_an_excursion "\startlocal ... \stoplocal" is the way to go - unfortunately my LMTX (2021.02.02 15:49) disagrees: \setuppapersize[A4][A4] \setuplayout[ ... header=15mm, ... ] \starttext \input tufte \page \startlocal \setuplayout[header+=20mm] \input tufte \stoplocal \page \input tufte \stoptext This fails: tex error > tex error on line XX in file ./local-layout.tex: Undefined control sequence XX >> \startlocal Do I need to load something in order to use this? Or has it been completely removed? And if so, is there a new alternative method to do the same thing? I was unable to find anything on this topic except https://www.mail-archive.com/ntg-context@ntg.nl/msg63602.html which raises the same question already in 2012 but never answers it IMHO. Thank you very much, Werner

verify if you are already postponing notes
by mf 15 Feb '21

15 Feb '21

Dear list, I'm typesetting XHTML and there is a couple of cases (tables and math), where I use \postponenotes ... \flushnotes in both their XML setups. The problem arises when I have math inside the cell of a table, so I get those commands nested: \postponenotes % <table> element \postponenotes % <span class="math"> element inside a cell \flushnotes % </span> closing math \flushnotes % </table> closing table With CSS selectors or XML machinery I can find those corner cases, but something like this would be better because more general: \doifnotpostponingnotes{\postponenotes} \dofipostponingnotes{\flushnotes} Is there a way to define those \doif... macros?
