weird issue with xtable
by Pablo Rodriguez 13 Aug '20

13 Aug '20

Dear list, in order to avoid a problem already reported (https://mailman.ntg.nl/pipermail/dev-context/2020/003694.html) I added to an indiviual table \startxtable[split=yes] (being the default in the document \setupxtable[split=repeat, header=repeat]). But I’m experiencing a weird issue with that approach. I get the following error message (that breaks compilation) when I add \setupxtable[split=yes]: You can't use '\prevdepth' in restricted horizontal mode The single document (actually, an XML file) compiles just fine, but when combined together to generate a PDF document over 1000 pages, I get the error above. My questions are: what is the restricted horizontal mode (as different from the horizontal mode)? Why might it be triggered with \startxtable[split=yes] in the huge source, but not in the single file? Many thanks for your help, Pablo -- http://www.ousia.tk

Help on tweaking alignment, page numbers and ToC
by Nicola 13 Aug '20

13 Aug '20

Hi, first of all, let me say *thank you* for the vast improvements on ConTeXt Garden! Browsing the documentation and finding stuff is so much easier and pleasant than it used to be (also the site seems faster). Thanks to the docs, dropcaps and protrusion have no secrets for me, but I am still struggling with some basic tasks (see the document below): 0. Push text to the bottom of the text area (see copyright). 1. Increase the space between Roman numbers and titles in the ToC. 2. Vertically center the ToC (wrt to the text area). 3. Suppress page numbers and headers in all blank pages. 4. Suppress headers in the front matter. 5. Style and position page numbers differently in the front and body matter (e.g., centered only in the front matter). As my full document uses environments, I would like most setups to be in the environment, if possible. E.g., is it possible to replace \setuphead[chapter][after={}] (see below) with an environment setup that applies only to the ToC?

tabulation and \textwidth
by Pablo Rodriguez 13 Aug '20

13 Aug '20

Dear list, I have this sample: \showframe \startsetups[footers] \starttabulate [|cw(.5\textwidth)| cw(.5\textwidth)|] [unit=0pt] \NC one\NC two\NC\NR \stoptabulate \stopsetups \setupfootertexts[\directsetup{footers}] \starttext \dorecurse{20}{\input{zapf.tex}\par} \startitemize[columns, two] \dorecurse{20} {\startitem\input{zapf.tex}\stopitem} \stopitemize \startitemize[columns, three] \dorecurse{15} {\startitem\input{zapf.tex}\stopitem} \stopitemize \startitemize[columns, four] \dorecurse{10} {\startitem\input{zapf.tex}\stopitem} \stopitemize \stoptext How can I avoid that tabulation alters the \textwidth so that it remains constant and item columns doesn’t afect it? Many thanks for your help, Pablo -- http://www.ousia.tk

Wiki New Extension Preview
by Taco Hoekwater 12 Aug '20

12 Aug '20

Hi, Some of you already know that I have been working on a wiki extension to control the editing of /Command pages. The goal is to eventually be able to easily export all of the reference documentation in the wiki to a separate system (for instance, Paul Mazaitis plans to create a full-blown reference manual). In the current situation, this is nearly impossible because there is so much variation in the content and quality of the wiki /Command pages (not to mention that many are missing). We also want it to be possible to merge improvements to the interface xml definitions by Wolfgang without loosing any existing documentation work. After some evenings and weekends of steady discussion with Paul, Wolfgang and some others on the wiki mailing list and a fair bit of hacking, this plan is now starting to come together. In short, we will switch to XML as the page model for newly created /Command pages. This makes editing a bit harder, but it allows much better quality control and (fairly) easy export and import. The new extension is not installed on the normal wiki yet, because it makes sense to see if we can get some of the bugs ironed out before we start working on actual /Command pages. It is my first ever Wiki extension and even my first non-trivial php code, thus I am certain there will be bugs. So, while the documentation pages are already on the normal wiki, any testing and/or experimenting has to be done on the test wiki. The documentation pages are here: https://wiki.contextgarden.net/Command https://wiki.contextgarden.net/Help:Command https://wiki.contextgarden.net/Extension:ConTeXtXML and there is a small todo list here: https://wiki.contextgarden.net/User_talk:Taco For playing around / experimenting / testing, have fun at https://wikitest.contextgarden.net/ (but read at least Help:Command first!) A useful landing page on the test wiki to start playing around is: https://wikitest.contextgarden.net/Allcommands which is a list of all the commands that are included in Wolfgang’s interface xml (and thus available to be documented using the new wiki extension). All the bright red links are currently undocumented commands. Clicking on one should bring you to the edit screen automatically, with a blob of XML preloaded, ready for you to start writing. All the dark red links are existing /Command pages. Almost all of those are traditional wiki text pagse. Following those links will bring you to a normal /Command page just like on the main wiki. If you want to see how one of those pages would look like in the new system, you’ll have to rename the existing page first. Be assured that nothing on the wikitest is permanent! As long as the browser url says “ https://wikitest.contextgarden.net/ ” you cannot destroy anything important. But don’t spend hours improving existing pages yet, this preview is intended for catching bugs in the extension only. Comments, Suggestions and Bug reports are more than welcome. Please direct those to me personally or (better) to the wiki mailing list: https://lists.contextgarden.net/mailman/listinfo/wiki Have fun! Taco

\checkpage in the TOC
by Willi Egger 12 Aug '20

12 Aug '20

Hello! humble, in another book I am trying to improve the list of contents. On different places occur page breaks which should be addressed and corrected. I tried to use the method \checkpage[][], however my attempts are not succesful. For your reference I include a screenshot of the problematic pagebreak. \definepagechecker [willi] [method=1,before=,after=,inbetween={\page}] \setuplist [chapter] [prefix=no, sectionnumber=no, headnumber=no, alternative=command, command=\Mychaptercommand, inbetween={\checkpage[willi][lines=4]} Thank you for advice! Kind regards Willi ]

\setfirstline is applied to whole paragraph
by Nicola 12 Aug '20

12 Aug '20

When I typeset the example at https://wiki.contextgarden.net/Command/definefirstline (reported below for your convenience), \setfirstline is applied to the whole first paragraph, which is laid out on a single line (hence, it is cropped at the edge of the page). Besides, the second \setfirstline is not applied at all, i.e., there are no small caps. If I comment out the first \setfirstline, then the second one does produce small caps, but again, a whole paragraph is set in small caps, not just the first line. $ context --version mtx-context | ConTeXt Process Management 1.03 mtx-context | mtx-context | main context file: /Users/nicola/Applications/context-osx-64/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2020.08.11 15:59 mtx-context | main context file: /Users/nicola/Applications/context-osx-64/tex/texmf-context/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2020.08.11 15:59 Nicola %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setupbodyfont [heros] %% important: smallcaps capable font! \definefirstline [italicfirstline] [ alternative=line, style=italic, ] \definefirstline [smallcapsfirstline] [ alternative=line, color=darkred, style=smallcaps, ] \starttext % \setfirstline[italicfirstline] \input knuth \par \setfirstline[smallcapsfirstline] \input knuth \par \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\title with extra content in toc
by jbf 12 Aug '20

12 Aug '20

Still dealing with \title, but am creating a separate thread because the question is different. As well as using \title within frontmatter (my previous question was about the header not appearing on final page if it is an odd/recto page) I am also using it in the main body for 'chapters' that I don't want numbered, and of course, have ensured that such \title items can appear in the TOC. But I want to add a one-word comment in brackets to the title that appears in the TOC, so that I get: Chapter title (comment).......... 5 or whatever the page number is. Is there are way I can add extra content to an item that appears in the TOC? In this case it would be the same comment in each instance, but my question assumes that there could also be a need for different comments, none of which appear in the 'chapter' title in the main body. Am using MkIV BTW, Julian

further to the earlier header question
by jbf 12 Aug '20

12 Aug '20

Clearly I am now getting myself quite confused where headers are concerned, and have sought as much info as I can on the wiki, but am not getting the desired results. We are talking about ConTeXt MkIV and a doublesided document. If I only use \chapter throughout and have my setup as: \setupheadertexts [{\hfill\getmarking[chapter]\hfill}][] [{\hfill\documentvariable{metadata:title}\hfill}][] then everything works as it should: Chapter title as header on recto pages and book title as header on verso pages. And as chapters change so does the header on the recto page. But this book has some 'chapters' that need to be unnumbered, for which I am using \title in the main body (as well as in frontmatter). Everything else about this choice works, except for the recto headers. If I use ONLY the setup above, then fairly obviously the numbered Chapters work, but those with \title continue to use the previous Chapter header for the recto pages (the verso pages with the book title is okay). So I understand that I may need to also give a command for the \title 'chapters' to act the way the other numbered chapters do. So I thought I could do this by simply adding the same set of commands above, but this time using title: \setupheadertexts [{\hfill\getmarking[*chapter*]\hfill}][] [{\hfill\documentvariable{metadata:title}\hfill}][] \setupheadertexts [{\hfill\getmarking[*title*]\hfill}][] [{\hfill\documentvariable{metadata:title}\hfill}][] However, when I do this, I get strange behaviour: now the numbered chapters do not show their recto header at all (the verso book title still appears though). The unnumbered \title chapters now show the headers but the same behaviour as indicated above occurs - the next numbered chapter after that carries the previous unnumbered chapter's title. Obviously I cannot do things the way I am doing it, but I cannot find how to do it. The other behaviour is the one I noted in an earlier post - if I get \title (used for an introduction) in the frontmatter to work with the correct headers, in the case of this Introduction (which is seven pages), the last of the recto pages does not bear the header 'Introduction'. Perhaps this is expected behaviour? Julian

header text on final page of section
by jbf 11 Aug '20

11 Aug '20

I am using \title within frontmatter for an introduction. The \setupheadertexts for title (recto and verso pages) is: \setupheadertexts [{\hfill\getmarking[title]\hfill}][] [{\hfill\documentvariable{metadata:title}\hfill}][] Now, that setup (this time for [chapter]) works correctly for chapters in the main body of text, but for some reason that I am unaware of, in the case of the 'Introduction', I get a header text ('Introduction' is the text) where I should */except for the last page of the introduction/* (There are seven pages in the intro, so it is the 7th, therefore odd-numbered page that is missing the header). I would like to understand why this is happening and, of course, be able to adjust something so that I do get the header on that page, as I do for the other pages. Julian

Page number 0 in Table of Contents with makeup
by Nicola 11 Aug '20

11 Aug '20

Consider this example: \definemakeup[toc][align=middle] \setuppagenumbering[alternative=doublesided] \starttext \startfrontmatter \startmakeup[toc] \placecontent \stopmakeup %\setuppagenumber[number=1] \startchapter[title={A}]\stopchapter \startchapter[title={B}]\stopchapter \stopfrontmatter \stoptext The first entry in the ToC has page number 0. I can fix it by uncommenting the commented line or by removing the makeup. Is this expected behaviour? If so, why? Nicola
