TeXlive 2020 / Gentoo Linux: ConTeXt does not find itself (sort of)...]
by mylists＠posteo.de 09 Sep '20

09 Sep '20

Hi, this is my first post to this mailinglist. I am no native speaker... if something sound somehow ... I will try to give my best.... ;) I am using GENTOO Linux, which compiles everything on the target instead of pulling ready compiled, binary packages into the system. I did a fresh install of Texlive 2020 via the package-manager "emerge". On Gentoo this is handled via a "virtual package", which can be configured beforehand to include or exclude certain parts. I choose to get the HUGE package (incluing LaTeX, ConTeXt, plainTeX and others). After the installation I tried to typeset examples of a LaTeX- and a plain TeX document, which works out of the box. Then I tried a ConTeXt document and it fails: context somefile.tex gave me: mtxrun | unknown script 'context.lua' or 'mtx-context.lua' . While searching the internet I found, that one has to run mtxrun --generate in advance. Doing so mtxrun starts to index my whole harddisk starting with my $HOME, from which I started it. It reports A LOT of "confusing file"s.... I searched the installed TeXlive installation for context.lua and mtx-context.lua -- they were installed and not "totally" missing. So I tried/guessed to run mtxrun --generate /usr/share/texmf-dist /usr/share/texlive-site and the file under $HOME were no longer indexed. context somefile.tex gave me the above mentioned error still, though. It "feels" like context does not respect setting made via the configuration settings under /etc/texmf... So I "hacked" (really, it was a crude hack/idea...nothing more) TEXMF and inserted export TEXMF=/usr/share/texmf-dist:/usr/share/texlive-site into my shells RC-file, restarted the shell and now context somefile.tex "worked"...: Each time it seems to re-index parts of ???, reports a lot of "confusing file"s but creates a valid looking pdf. I think, the package setup provided by GENTOO has a problem I want to help to fix that...but I have no clue, what the real culprit is here... Setting TEXMF this way feels like a random and accidentally working hack and I already feel the next problem raising up at the horizon... Some additional problems: tlmgr does not work mtxrun partially does not find its own modules mtxrun --variables lists a LOT of unset environment variables ... It looks like some basic and fundamental "initial" environment variable is missing. But I need a knowledgeable guru before I am able to get nearer to the root of the culprit. Thank you very much in advance for any help offered! \cheers Meino

Wrong page number when placefigure spans full page in columnset
by Charles Vejnar 09 Sep '20

09 Sep '20

Hi, When I place a figure within a columnset and that figure takes a full page then the page number in the header is incorrect. Page number is the same as the previous page but on the next page it's correct. Please see example below and attached showing page 2 twice with pages numbered 1, 2, 2, 4, 5. If I reduce the height of the figure (from 15 to 12cm for example), then some main text gets added on the page and page number (3) becomes correct. Is that a bug or am I doing something wrong? Thanks for your help.

Input file name containing full stop "."
by Christoph Reller 09 Sep '20

09 Sep '20

Dear list, I am using ConTeXt LMTX Version 2020.09.05 21:18 with an input file named, e.g., "test.test.tex". When compiling, ConTeXt generates files "test.log", "test.tua", "test.pdf". ConTeXt MKIV used to produce files "test.test.log", "test.test.tua", "test.test.pdf". Is there a way for ConTeXt LMTX to process input files that contain full stops consistently? I am aware of the "--result=..." option, but what about the "...tua", "...log" and synctex files? This is a serious problem when running multiple compilations in parallel, e.g., on "test.a.tex" and "test.b.tex", because both processes use the same "test.tua" file. Cheers, Christoph

styling individual parts of ToC entry
by jbf 09 Sep '20

09 Sep '20

Now that with Hraban's invaluable assistance I am able to include title, subtitle, author as and when necessary in the ToC and put them on the same line if I need to, I have two questions that I have not found a satisfactory solution to after playing around with various possibilities. I need: (1) the author's names lined up vertically throughout the ToC, and (2) the first part of the entry (e.g. Foreword) to be bold, but the author name to be regular text. An adjusted version of Hraban's setup can show what I have tried by way of example: %---------------- \define[1]\TitleTocEntry{% #1\hskip 1cm% title \structurelistuservariable{author}% } \setuplist[title][textstyle=bold, textcommand=\TitleTocEntry, ] %--------------- /Question 1:/ /How to get the two author names to line up vertically./ Given that I have both a Foreword and a Preface, I am using \title for these. And both have separate authors. The titles will be simply 'Foreword' and 'Preface', obviously. *Foreword Author name* *Preface Author name* I am using \hskip 1cm to separate the authors' names from either of those two words. But this does not give me the kind of exact positioning I need to get the two author names directly underneath each other in the list. I have tried various alternatives to \hskip, but none of them can give me the correct proportional distance. The distance is obviously being controlled by the fact that 'Foreword' is 8 characters and 'Preface' is 7. Is what I want only obtainable with a table setup? The issue might or might not be more complicated when I get to main chapters, where the author names need to line up with the Foreword and Preface author names as well. There will be, e.g. Chapter One Title Author name // /Question 2:/ /How to independently get Foreword and Preface to be bold, but the authors' names to be regular./ \setuplist offers me options like textstyle, pagestyle, numberstyle, but they apply to everything (both Foreword/Preface and Authors' name are bold). I thought perhaps I could control it from within the document, e.g. \starttitle[title={\ss\bf Foreword}][author={A. Uthor}] But that does the same - both Foreword and A. Uthor end up bold. And besides, I also want to style the ToC independently of the heads if I can. The wiki and various manuals do offer various tips on modifying the ToC, but I cannot find anything regarding the two questions above - not yet, anyway. If someone knows where, please point me to it.

Column not Balancing, Footnote is Missing
by Art Chimes 08 Sep '20

08 Sep '20

Greetings, list. My first post here. Please be gentle! The command \contextversion reports I am using 2020.09.03 20:03 on Windows 10. The MWE below produces a column and a half of text, not balanced (despite the \setupcolumns [...balance=yes...] command. Also, the footnote *number* appears on the PDF, but the *text* of the footnote doesn't. However, when I use the online compiler (live.contextgarden.net, reported version 2020.06.30 17:30, older than mine), the footnote text *does* appear, though the columns are still not balanced. %%%%%%%%%%%%%%%%%%%%% \usemodule[ipsum] \setupfootnotes[location=page,rule=on,bodyfont=8.5pt] \setupcolumns [n=2,balance=yes,blank=line] \starttext \chapter{Footnote Test — \contextversion} \startcolumns \ipsum Cursus metus aliquam eleifend mi in nulla posuere sollicitudin aliquam. Id aliquet risus feugiat in ante metus dictum at tempor.\footnote{Thor, A.U.: {\it Latin 101 for Dummies} (Rome, Dummies Pub., MCMLXXIX)} \ipsum[alternative=lines,n=20] \end columns \stoptext %%%%%%%%%%%%%%%%%%%%% Question (1) : Why don't the columns balance, and how can I fix it? Question (2) : Why does the footnote appear only with the online compiler? What am I doing wrong? Question (3) : For extra credit: How can I get the footnotes to stretch the entire width of the text block instead of the width of one column? I did try to parse the somewhat opaque (to me) information in the wiki and looked in the mailing list archives, but I didn't find the information I needed. Thank you for any help you can offer.

Appendix question
by jbf 08 Sep '20

08 Sep '20

A (hopefully) simple question this time: Why would my appendices be labelled as Appendix One, Appendix Two etc., instead of Appendix A, Appendix B? I thought Appendices would normally be labelled alphabetically, not numerically. So I get APPENDIX as the label, I have: \setuplabeltext [en] [chapter={\bf Chapter }, appendix=APPENDIX ] But elsewhere I have: \setupheads[chapter][indentnext=no,conversion=Words,distance=.25em] So is that what is affecting my appendices, and if so how do I do it so that Chapters get words (One, Two, etc) and Appendices get letters (A,B, etc)?

Fullwidth topfigure with caption in the margin
by Mikael Sundqvist 08 Sep '20

08 Sep '20

Hi, Is there a way to have a fullwith topfigure with caption in the margin so that the figure does not interfere with the text? My try is %%%%%%% \setuplayout[ rightmargin=2in, rightmargindistance=0.375in, width=4.125in, ] \showframe \definecolor [transparentred] [r=1,t=.5,a=1] \definefloat[topfigure][topfigures][figure] \setupfloat[topfigure][ default={margin}, location=flushleft, maxwidth=6.5in, ] \setupcaption[topfigure][ number=no, location=bottom, style={\switchtobodyfont[8bp]}, ] \starttext \dorecurse{4}{\samplefile{knuth}} \startplacetopfigure[title={\samplefile{ward}}] \blackrule[width=6.5in,height=2in,color=transparentred] \stopplacetopfigure \samplefile{knuth} \stoptext %%%%%% but, as one can see on page two, the text from the previous page just continues under the image. I want the "larg-scale user..." to start below the image. It would be good if it was also possible to configure the distance between the image and the text. (I guess one option would be to not use a margin figure, and use default=top, but then I don't know how to handle the caption.) /Mikael

Fwd: Re: styling individual parts of ToC entry
by jbf 07 Sep '20

07 Sep '20

-------- Forwarded Message -------- Subject: Re: [NTG-context] styling individual parts of ToC entry Date: Tue, 8 Sep 2020 12:39:05 +1000 From: jbf <roma83537(a)gmail.com> To: Wolfgang Schuster <wolfgang.schuster.lists(a)gmail.com> Wolfgang, I have tried an MWE below but I think I am hopelessly lost at this point. It is not producing anything like what I want. But at least let me indicate what I have tried: (1) I have defined two different 'title' items (Foreword and Preface unnumbered) since both of these require an author name of the kind produced by the \ChapterListCommand. Do I also need a \TitleListCommand for these? The \ChapterListCommand seems to call in a chapter number, and I don't want one in the Frontmatter items like foreword and preface. I didn't know how to adjust that definition to leave out the number. I did try a renamed copy of it, leaving out the line: \hbox to 3cm{\currentlistsymbol\hss}, but that made no difference. (2) And since I also need some sections with an author (but the chapter they are in has no author), I defined a 'mysection', though I have only tried to 'call in' the Foreword so far in the text below, to see if that at least worked - but it doesn't. (3) I also assumed that having defined foreword, preface and mysection, they would need to be in a \setupcombinedlist. (4) And finally, I thought I would then need a \setuplist and \setuplabeltext for Foreword (as indeed I might for the other two as well, but to start with, I wanted to get one of them working at least). MWE: \definehead [foreword] [title] \definehead [preface] [title] \definehead [mysection] [section] \setupcombinedlist[chapter,foreword,preface,mysection,section, subsection] \define[3]\ChapterListCommand {\hbox\bgroup \hbox to 3cm{\currentlistsymbol\hss}% number + labeltext \vtop\bgroup \hsize\dimexpr\makeupwidth-3cm\relax \doifsomething{\rawstructurelistuservariable{year}} {{\it\structurelistuservariable{year}}\crlf}% \currentlistentrytitle % title \doifsomething{\rawstructurelistuservariable{author}} {\crlf{\bf\structurelistuservariable{author}}}% \hfill\currentlistentrypagenumber % pagenumber \egroup \egroup} \define[3]\TitleListCommand {\hbox\bgroup \hbox to 3cm{\currentlistsymbol\hss}% number + labeltext \vtop\bgroup \hsize\dimexpr\makeupwidth-3cm\relax \doifsomething{\rawstructurelistuservariable{year}} {{\it\structurelistuservariable{year}}\crlf}% \currentlistentrytitle % title \doifsomething{\rawstructurelistuservariable{author}} {\crlf{\bf\structurelistuservariable{author}}}% \hfill\currentlistentrypagenumber % pagenumber \egroup \egroup} \definehead [foreword] [title] \definehead [preface] [title] \definehead [mysection] [section] \setupcombinedlist[chapter,foreword,preface,mysection,section, subsection] \setuplist [chapter] [label=chapter, alternative=command, command=\ChapterListCommand] \setuplabeltext [en] [chapter=Chapter ] \setuplist [foreword] [label=foreword, alternative=command, command=\TitleListCommand] \setuplabeltext [en] [title=Foreword ] \starttext \completecontent \starttitle [title={Foreword}] [author={Author Name}] \unknown \stoptitle \startchapter \startchapter [title={Chapter title}] [author={Author Name},year={1980--2000}] \unknown \stopchapter \stoptext %%% Let me remind you of what I am trying to achieve.

Re: [NTG-context] Can't output direct glyphs either in MKIV
by Andres Conrado Montoya 07 Sep '20

Hi Taco, thanks for the input. Your example works, and produces the glyphs. Pdf attached, I hope this system allows it (only 36.3 kB). "u101F2" is the unicode name for the glyph. I would guess, according to what you told me, that the code point would be "00024", but honestly, I have no idea. This used to work some months ago. -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

About Metapost and patterns, tessellations, fractals, etc.
by Jairo A. del Rio 07 Sep '20

07 Sep '20

Hi, list! I have a problem with some graphics in Metapost. I've tried to replicate the Koch curve cited here using ConTeXt: https://en.wikipedia.org/wiki/L-system To my own amusement, the patterns seem to appear. However, when I try with a number from 6, ConTeXt stops doing anything or output looks wrong (see attached PDF, please). \startluacode userdata = userdata or {} function userdata.koch(n) local init = "F" local base = init local replacement = "F+F-F-F+F" for i = 1, n do init = init:gsub(base, replacement) end return init end function userdata.kochlen(n) return string.len(userdata.koch(n)) end function userdata.kochchar(k, n) return string.sub(userdata.koch(n),k,k) end function MP.kochlen(n) mp.print(userdata.kochlen(n)) end function MP.kochchar(k,n) mp.quoted(userdata.kochchar(k,n)) end \stopluacode \startMPpage[instance=doublefun] def koch_curve(expr n, u) = save p; save q; save angle; pair p, last; path q; numeric angle; p:= origin; q := origin; angle := 0; for i = 1 upto lua.MP.kochlen(n): if lua.MP.kochchar(i,n) = "F": q := q -- ((point infinity of q) + dir(angle)); else: if lua.MP.kochchar(i,n) = "+": angle := (angle + 90) mod 360; else: if lua.MP.kochchar(i,n) = "-": angle := (angle - 90) mod 360; fi fi fi endfor; draw q scaled u; enddef; koch_curve(5, 5mm); %koch_curve(6, 5mm); does not give a right output \stopMPpage Maybe there's a fabulous trick to make it work with larger numbers, but I don't know it. I'm aware of a TikZ library for Lindenmayer systems, but it's not a possibility for me in this case (I add the remark just in case). Thank you in advance, Jairo :)
