chapter counter?
by Henning Hraban Ramm 26 Aug '24

26 Aug '24

Hi, I’d like to check the chapter number like \ifodd\rawcountervalue[chapter] What an odd chapter! \fi but apparently the counter isn’t called "chapter", or I’m doing it wrong otherwise. Could you enlighten me? Hraban

horizontal line in math align environment
by niklas＠vonhirschfeld.eu 26 Aug '24

26 Aug '24

Hi everyone, I’m working on creating a horizontal line within a math align environment that spans the entire equation, rather than being restricted by the columns. My current "solution" is to use `\hl`, as shown below: ``` \startformula \startalign \NC a + b \NC = c \NR \NC d + e \NC = f \NR \NC \hl[4]\NC \hl[4] \NR \NC g + h \NC = i \NR \stopalign \stopformula ``` While this somewhat works, it’s not exactly what I’m aiming for. I need the line to extend across the full width of the equation. My final goal is something like this: \startformula \startalign[n=11] \NC \NC 1001 \NC \rightarrow \NC 1000 \NC + \NC 000 \NC + \NC 00 \NC + \NC 1 \NR \NC + \NC 100 \NC \rightarrow \NC \NC \NC 100 \NC + \NC 00 \NC + \NC 0 \NR % here should be a horizontal line \NC \NC \NC \rightarrow \NC 1000 \NC + \NC 100 \NC + \NC 00 \NC + \NC 1 \NR \NC \NC \NC \rightarrow \NC 1101 \NC \NC \NC \NC \NC \NC \NR % here should be a horizontal line \NC = \NC 1101 \NC \NC \NC \NC \NC \NC \NC \NC \NR \stopalign \stopformula The horizontal line should not take the height of a hole line. I also considered using `\underline{}`, but it wont span across multiple columns. I’ve heard of `\noalign`, but I couldn’t find any helpful resources on it, and my attempts to use it were unsuccessful. In LaTeX, the desired outcome would be something like this: ``` \begin{equation*} \begin{split} x &= 1 \\ y &= 2 \\ \hline x + y &= 3 \end{split} \end{equation*} ``` Does anyone have suggestions for achieving this effect in ConTeXt? Thank you in advance for your help! Best regards, Niklas von Hirschfeld

understanding units / dimensions
by Henning Hraban Ramm 26 Aug '24

26 Aug '24

At the meeting I noted a few units that I didn’t know about, while I already knew many. * general units: in, m, cm, mm (ft?) * typographical units: pt, dd, bp, pc, cc, sp * font related: em, ex, fs, fa, fd, fc, ch * layout related: pw, ph, tw, th, cw, cd, lw, hs, vh * frame related: fw, fh, fo * funits: dk, es, tv, eu Are there even more? (Did you know all of them? This will be in the test…) Questions: How differs "1" from "2"? * em fs * lw hs * ph vh I want to update https://wiki.contextgarden.net/Dimensions Hraban

digits / units setup
by Henning Hraban Ramm 25 Aug '24

25 Aug '24

According to docs, \setupunit[method=3] should change the rendering of numbers in \unit{10,123.99 mm} or \digits{10,123.99} to “10\,123,99”, but it doesn’t. \setdigitmode{3} works, though. Hraban

Is there a short-cut to adding sub-categories for index entries?
by Joel 25 Aug '24

25 Aug '24

I have a document with thousands of index entries. Here’s a samplecode: \starttext Some people livedin \index{cliff-dwelling}cliff-dwellings, while others lived in\index{lean-to}lean-tos. \placeindex \stoptext This produces anindex like this: c cliff-dwelling 1 l lean-to 1 I’d like to createan index with much more sub-categories to find the same entries, forinstance, a category of “dwellings”: c cliff-dwelling 1 d dwellings cliff-dwelling 1 lean-to 1 l lean-to 1 As I’m aware, theway to code this is as follows: \starttext Some people livedin\index{cliff-dwelling}\index{dwellings+cliff-dwelling}cliff-dwellings,while others lived in\index{lean-to}\index{dwellings+lean-to}lean-tos. \placeindex \stoptext I’m wondering ifthere is a short-cut means to set this up, such that if I can tellthe document that any time it sees “cliff-dwellings” in an index,it will also add its page numbers to under “dwellings+cliff-dwelling”? In other words, is there an easierway to add these categories, then to go through the entire documentand mark them? I already have a list of all the words. For instance, in my above code, I must find every \index{cliff-dwelling} entry and add a \index{dwellings+cliff-dwelling} next to it...which would take hundreds of hours if I did that for every word. Is there a quicker way to tell it always also add it under "dwellings" too? --Joel

Any way to forbid boldface for a section of text?
by Joel 25 Aug '24

25 Aug '24

If there any way to forbid boldface text for a section, e.g.: \starttext \stopboldface\input file\startboldface \stoptext Assume file.tex includes some boldface commands there, how to tell it to just ignore them temporarily, then resume normal behavior latter? --Joel

Does ConTeXt still support ePub output?
by Joel 24 Aug '24

24 Aug '24

I recently learned I need to produce an ePub copy of my document, which will be used to produce braille and other versions of my file for people with limited or no vision. As I understand this is just like a ZIP file containing a bunch of HTML files with some links to each other. Though I could manually go and create tons of HTML files for it, I notice the ConTeXt Garden does mention ePub output as a possibility, but this page was updated in 2014, and I don't see any of hte sample code working. Is ePub still a file format that ConTeXt can output? Does it require a significant rewrite of ConTeXt document code to be produced or is there a simple way to output this format? --Joel

OT: specifications and reality
by Henning Hraban Ramm 24 Aug '24

24 Aug '24

Hi, since Hans often refers to bad and changing “standards” (e.g. PDF, MathML, ePub…) and Taco told us about the mess of RTF: You’re not alone. There’s the ONIX[1] XML standard for publication data, prominently used by the monopolist VLB (Verzeichnis lieferbarer Bücher, German catalogue of books in print). A friend and I had the idea of an open book catalogue (for all publishers and bookshops that want to participate), and they’re setting up a proof of concept. Just got a message: * The examples from the ONIX homepage have errors if you check against their “strict” schemas. * The catalogue of our publishing house, exported as ONIX from VLB, has errors when checked against the “not strict” schema, i.e. VLB generates faulty data. Beautiful standards… Hraban [1] https://www.editeur.org/83/Overview/
