Minion Pro confuses italic correction
by Henri Menke 13 Feb '19

13 Feb '19

Dear list, The Minion Pro font, as distributed with Adobe Reader, confuses the ConTeXt italic correction. The MWE below will fail with luatex warning > node filter: error: ...ext/tex/texmf-context/tex/context/base/mkiv/typo-itc.lua:130: attempt to compare nil with number It's probably the font that is faulty but I guess ConTeXt shouldn't crash in that case. Cheers, Henri --- \mainlanguage[de] \definefontfeature[default][default][itlc=yes] \setupitaliccorrection[global, always] \setupbodyfontenvironment[default][em=italic] \setupbodyfont[minion,11pt] \starttext {\em riften}, \stoptext

Automatic thousands separation in \unit
by Marco Patzer 09 Feb '19

09 Feb '19

Hi! I'm wondering if there's a way to have automatic thousands separation in the \unit command? \spaceddigits does that, but it doesn't work inside \unit. And using both would be quite verbose to write. Example: \starttext %% no thousands separation \unit{123456789 volt} %% manual thousands separation works \unit{123,456,789 volt} %% automatic thousands separation, but not using \unit \let\spaceddigitsseparator, \spaceddigits{123456789}\,V %% fails, no output \unit{\spaceddigits{123456789} volt} \stoptext Marco

right figure at bottom of page can narrow text block on whole next page
by Sanjoy Mahajan 06 Feb '19

06 Feb '19

Dear List, A figure near the bottom of the page can narrow the text block on the whole next page. I noticed the problem when typesetting my (next) book. But the book is more a maximal than a minimal example. However, from it I made the minimal example included below that uses no external figures. Figure 2 is the bottom of the page and the paragraph flows to its left with a correspondingly narrower text block. So far, so good. But the text block also narrows for the entirity of page 2 and for the first two lines of page 3. I've found the problem on the MkIV 2019.01.07 and 2019.01.28 betas (all on Debian amd64), as well as on the live ConTeXt (which is the 2019.01.28 beta). -Sanjoy ================== start margin-figure-region.tex ===================== \definepapersize[bookcrop][width=137mm,height=221mm] \setuppapersize [bookcrop][bookcrop] \setuplayout[marking=on, location=middle, backspace=13.5mm, width=middle, topspace=32bp, header=10bp, headerdistance=26bp, footerdistance=16bp, footer=10bp, height=578bp, ] \setupinterlinespace[line=1.3em] \setupbodyfont[times,10bp] \starttext \input knuth Silly para Silly para \placefigure[right]{}{\framed[width=100bp,height=75.75bp]{\null}} \input knuth \dorecurse{8}{\par Silly para} \placefigure[right]{}{\framed[width=100bp,height=60.75bp]{\null}} \dorecurse{32}{Silly text } \dorecurse{3}{\input knuth \par} \stoptext ================== end margin-figure-region.tex =====================

getting ConTeXt results back to Lua (for typesetting solutions at end of document)
by Sanjoy Mahajan 01 Feb '19

01 Feb '19

Dear List, I'm trying to have problem solutions automatically collected, each with its corresponding problem number, e.g. 2.3, and then typeset at the end of a document. Thus, I imagine something like \startproblem{A problem title} % Problem 1.1 A question \startsolution An answer \stopsolution \stopproblem And then the solution(s) would appear at the end (with the "1.1" remembered from when the problem was typeset): Solution to Problem 1.1. An answer It seems that buffers are the way to do this. But I cannot quite get the automatic numbering to work. The delayed evaluation and information passing between lua and ConTeXt has me confused and tangled in a knot. Below is a minimal almost-working example. The issue is in the line {\ctxlua{userdata.addTempToBuffer('#1', [==[\getnumber[problem]]==])}} which ends up putting the verbatim string "\getnumber[problem]" into the temp buffer, rather than the typeset result, which would be something like 1.1 or 1.2. I've read the cld-mkiv.pdf manual, but I must be missing a simple solution to getting ConTeXt to send back the result of \getnumber[problem]. I've also tried the analogous context.getnumber({"problem"}), though without success. Does anyone see what I am missing?

Headings vs. enumerations
by Clyde Johnston 01 Feb '19

01 Feb '19

I have a document that contains a numbered enumeration that spans 107 pages - it's a legal document where \items are clauses. I would like to put level one of the enumeration in a table of contents. I have read the available documentation but I am not clear whether I should make level one headers, whether I can utilise the \starthead in \startitemize or whether I can create a list from the level one headings to create the table of contents. How is best to tackle this problem? Thanks, Clyde MWE #1: \starttext \placecontent[alternative=c] \startitemize[n,repeat] \starthead{A heading}\stophead \startitemize[n,repeat,2*broad] \starthead{A sub-heading}\stophead \startitemize[n,repeat,3*broad] \item \input knuth \stopitemize \stopitemize \stoptext MWE #2: \starttext \placecontent[alternative=c] \chapter{A heading} \startitemize[n,repeat,2*broad] \starthead{A sub-heading}\stophead \startitemize[n,repeat,3*broad] \item \input knuth \stopitemize \stopitemize \stoptext

New logo proposal
by Paul Schalck 31 Jan '19

31 Jan '19

Dear ConTeXt users and developers, I want to submit a new ConTeXt logo to you (link to GitLab project): https://gitlab.com/schickele/new-context-logo I made this logo in February 2018. At the time, I was planning to do some video tutorials on ConTeXt (still work in progress), and I wanted a nice looking visual clue for the thumbnails. Recently, I made a few minor tweaks and thought it would be the right time to put it out there. The logo comes in two different layouts (hexagonal and horizontal), and each layout comes in two color variations (multicolored and blue). The hexagonal layout is borrowed from the unofficial ConTeXt logo that has been around for some time. I like the idea of a clean geometrical form, and the hexagon reminds me of chemistry formulas -- one of the many application fields of ConTeXt. The seven colors have mainly an esthetic purpose. They also denote the flexibility of ConTeXt. I've added a monochromatic blue version because shiny, saturated colors are not suitable for every case, and blue is strongly associated with ConTeXt to me. Blue is also a reminder of Mark IV and LuaTeX. The letters are set in Din17 EF, which I've licensed. I like its simple shapes combined with a round and soft touch. It avoids consciously the very connoted Computer Modern and can be seen as a modernized and also Europeanized interpretation of the TeX tradition. This logo is just a humble proposal. Perhaps it is of some use to someone. It could also make someone else want to create and share his or her logo -- that would be great. I'm using ConTeXt since 2006/07 for almost everything that contains text: letters, presentations, invitations, résumés, certificates, manuals, reports, flyers, university papers, book typesetting, exercise sheets, song sheets, and I'm still amazed by how powerful, flexible and reliable it is. Thanks to the whole community -- and particularly to the Dutch wizard -- for making this possible! Greetings from Leimen, Germany Paul Schalck

Hello again, as many critics go towards "I don't see any coherence" or "to me it's just a random bunch of colored letters" or "it's hard to read the word CONTEXT", some afterthoughts in that regard (difficulty, randomness). Personally, I like visual material that catches my attention, but does not give all away at first glance. For example a good poster or book cover. It invites me to spend time on it. And I don't have the feeling that the designer thinks I'm stupid. ConTeXt is quite sophisticated, its logo can also be a little bit more complicated than your average sportswear brand. Any color choice is arbitrary to some extend. The colors I've used cover the entire hue range and are at equal distance apart (common in multicolored designs). This denotes to me not only the flexibility, and the fun of using it, but also the comprehensiveness of ConTeXt. Not only can you use ConTeXt in very different situations, you can use it in every situation (that requires typesetting). My 2c! Greetings, Paul

New logo proposal

Hello, thank you all again for your reactions. A lot of interesting comments here on logo design in general and a ConTeXt logo in particular. I'm honored that the new design has found its way into the Wiki, thanks Taco! @Lukas: I like the idea. Would be worth a try. @Floris vM: I'm glad that my nemesis on the matter felt himself challenged to make his own proposal. While I think it's too minimalistic (only insiders know what 'CTX' stands for), I like your idea of the subscript 'T'. Your concept with the crosses reminded me of the visual identity of Amsterdam. I do not see, however, how it reflects better "typesetting beautiful readable typography". And it lacks some colors ,-) Greetings! Paul

Hello, thanks for your feedback. Again, I don't want to impose or dismiss anything. I wanted to share this because I believed somebody else in the ConTeXt community could be interested. @Taco: Actually, I stumbled upon the nice ConTeXt group logo recently and was wondering who made it. To answer your questions: I tried to avoid any logic or rainbow-type color sequence to create something more unique. The first square had to be in blue and the middle area in a warm color. (I played around a lot with the color combinations.) Regarding the outside circle: I tried different variations, with and without a surrounding circle or round background, with and without rounded squares, and was most pleased with this solution. It's true, "clean and simple" can easily lead to "too informal". @Clyde J: Valid point. I use the logotype with the subscript 'E' whenever I can in inline text. @Floris vM: Font, spacing, overall appealingness. No Helvetica/Nimbus Sans, which has less meaning to me for ConTeXt than a DIN-ish/technical one. Colors are fun. If you don't see it this way, it's perfectly fine. @Alan B: I've uploaded MetaPost files of the main version. Yes, the horizontal version is not very exciting nor very TeX-aware. I made this one primarily because I wanted something small for a little GUI script. Now I think it's just superfluous. Greetings! Paul
