horizontal headalternatives ignore indentnext
by Henri Menke 27 Feb '19

27 Feb '19

Dear list, If I choose the headalternative to be of horizontal type, e.g. “text”, the head placement will ignore the indentnext option. This can be traced back to the \strc_rendering_stop_placement macro where there is a check \ifconditional\headisdisplay \useindentnextparameter\headparameter \else \ignoreparskip \noindentation % recently added, was a bug \fi If the headalternative is vertical, \headdisplay is true, if it is horizontal, \headdisplay is false. It is easy to see that indentnext is not treated on equal footing for these two, in fact, indentation is generally ignored for horizontal headalternatives. Commenting out \noindentation at least gives indentation in the following paragraph but that is not a proper solution. Below you can find a MWE with the fix from above applied. Try commenting in and out the \noindentation and see what happens to the second paragraph after the heading.

Re: [NTG-context] When newsizing an external figure bei [width=<some pt>], what will be its height in pt and viceversa?
by Jeong Dal 27 Feb '19

27 Feb '19

Dear Rudolf, It is working for me. Using my figure, I got (45126287sp,31048991sp) (1372,944) As Hans said, either change ~ to some path or set the directory of externalfigure.

Hi, I would like to typeset the runtime information that context displays at the end of typesetting: mkiv lua stats > runtime: 174.639 seconds, 913 processed pages, 913 shipped pages, 5.228 pages/second system | total runtime: 526.583 seconds Is this stored in any environment key? How could I access it? Thanks Thomas

Latest changes in some size registers
by Martin Bruchanov 26 Feb '19

26 Feb '19

Hi all, I have some very condensed documents which should fit on one page: http://gnulinux.guru/bash_cheatsheet.pdf Without any major change in style definition, there is more space around sections or itemize: http://gnulinux.guru/bash_cheatsheet_diff.pdf Source code is here: https://github.com/BruXy/gnulinux.guru/tree/master/bash_tahak Did I miss some update which has introduced some different length settings? I have version: 2019.02.14 16:57 Regards, BruXy

cross references to chapters in a book
by Robert Zydenbos 25 Feb '19

25 Feb '19

Dear wizards of ConTeXt, In the final stage of completing a book project, I was wondering how to automatize cross references to chapters. I’ve already figured out how to refer to pages (using “\at[REFERENCE]”), but how is this done with chapters? I’m apparently too simple-minded to understand the manual (and I don’t understand the differences between \reference, \textreference, \in, \about). Robert

em-dash ligature is converted to en-dash in the generic fontloader
by Ulrike Fischer 25 Feb '19

25 Feb '19

As reported on the dev-luatex list --- is converted to an en-dash (instead of em-dash) if there are no spaces around the ---. We could now reproduce the problem also with the generic fontloader: it appears only with mode=node. I'm using the files from 2019-02-14, but the problem appeared first in the files from 2018-11-18): \font\test={file:texgyreheros-regular.otf:+tlig;mode=node;}\test dashes-these % gives dash dashes--these % gives en-dash dashes---these % gives en-dash WRONG dashes --- these % gives em-dash em-dashes---these % gives em-dash \bye context is not affected, there the code works fine. -- Ulrike Fischer https://www.troubleshooting-tex.de/

\mathematics might be missing \everymathematics
by Henri Menke 25 Feb '19

25 Feb '19

Dear Hans, In the following example I want to locally set lcgreek=normal but it is not picked up because the attribute is not propagated. When I enter \everymathematics manually it works fine. Is this by design or is this a bug? MWE below. Cheers, Henri --- \starttext The greek letter should be upright here \m[lcgreek=normal]{\varphi} \m[lcgreek=normal]{\the\everymathematics\varphi} \stoptext

Re: [NTG-context] about the color of sidebar

Dear Mohammad Hossein Bateni, > 2019. 2. 25. 오후 1:27, ntg-context-request(a)ntg.nl 작성: > > I have never used the sidebar mechanism, but there is a "rulecolor" option > in setupsidebar. Maybe that's what you're looking for. > > You can look up the commands and their options in "i-context.pdf" file. Thank you for the reply. I found the command “\setupsidebar”. The following example is working well. %%%%%%% \definecolor[dGreen][r=0,g=.4,b=0] %\setupsidebar[rulecolor=(.4green)] \setupsidebar[rulecolor=dGreen] \starttext \startsidebar \samplefile{knuth} \stopsidebar \stoptext %%%%%%%%% The reason of putting “\definecolor…” is that “[rulecolor=(.4green)]” is not working as in MetaFun, while [rulecolor=green] is working well. Because of this, I can remove my definition of sidebar from my environment. Thank you again. Best regards, Dalyoung

Here is a question: Is it possible to change the color of the bar or any other options? There is no commnad like “\setupsidebar” in the wiki. Thank you. Best regards, Dalyoung
