registers in footnotes as page glossaries
by Pablo Rodriguez 31 Aug '24

31 Aug '24

Hans, I wonder whether MkXL may have page registers for footnotes. This would be great to have page glossaries, such as in https://geoffreysteadman.com/wp-content/uploads/2017/08/lysiascrito-24aug17… (first apparatus). To be fair, I have asked that a while ago (with MkIV). It would be great to have these page glossaries as language aids. Right now, they need to be composed manually (using a word processor, no TeX). Many thanks for your help, Pablo

Hi, I have plotted a log function and I want to draw an xy axis grid. Below is the code \starttext \startMPcode draw function(1,"x", "log(x)", .1, 10, .01) scaled 1cm; for i = 0 upto 10: draw (i*cm, -5cm) -- (i*cm, 5cm) dashed; endfor; for i = -5 upto 5: draw (0, i*cm) -- (10cm, i*cm) dashed; endfor; \stopMPcode \stoptext My first for loop draws lines but the second gives me an error.

BUG REPORT: Italic Correction in ConTeXt LMTX
by contact＠vladimirgrbic.com 30 Aug '24

30 Aug '24

Hello, I started using ConTeXt LMTX 2 days ago and after some initial testing I noticed an unexpected behavior regarding italic correction. In short, I cannot seem to produce italic correction like I could in plain TeX or even LaTeX. I've asked the question on TeX StackExchange and another user confirmed the suspicion in his answer. I would suggest you take a look at it because the formatting of the question and the answer is prettier than in this plain text email. Furthermore, a person who provided the answer already did some research. See the question here: https://tex.stackexchange.com/questions/724568/how-to-invoke-italic-correct… Here is what I observed: Compare the kerning produced in between 'r' and 'p' in the word "airport" when italic correction is applied in plain TeX (compiled with `pdftex`) and in ConTeXt LMTX (compiled with `luametatex`). Here are the minimal working examples. Plain TeX ``` airport (regular font) {\it air\/}port (italic correction applied) {\it air}port (no italic correction applied) \bye ``` ConTeXt LMTX ``` \starttext airport (regular font) {\it air\/}port (italic correction applied) {\it air}port (no italic correction applied) \stoptext ``` Please confirm if this, in fact, is the issue/bug or if I am not approaching this correctly. I am brand new to ConTeXt, so it could be me. Thank you in advance! Vladimir

Defining mathsymbols from unicode char
by Jethro Djan 29 Aug '24

29 Aug '24

Dear all, 1. I am trying to define the "pitchfork" unicode character( https://unicodeplus.com/U+22D4) to use in ConTeXt as stated on page 387 of new math manual authored by Hans and Mikael: \definemathsymbol[pitchfork][relation]["22D4] It works with some unicode characters and not others (like this character). What can I do to make it work? 2. I would like a \not\perp symbol but it doesn't draw the stroke on top of the symbol. I know you could manipulate this in a plain TeX but I am thinking the mechanism in ConTeXt would be different. How can I achieve this? Also how can I get the \notperp symbol in the accepted answer of https://tex.stackexchange.com/questions/27651/symbol-about-not-orthogonalit… ? Thanks. Jethro

MetaPost dirtree?
by Henning Hraban Ramm 29 Aug '24

29 Aug '24

Hi, did someone already create directory trees with MetaPost? It should be quite easy, but I couldn’t find examples and was thinking about porting the LaTeX dirtree package (i.e. look at the code and try to implement something similar in Lua and MP). I have ideas… (but I have always too many of them). So far, I used the output of `tree`, and that’s not really beautiful. Hraban

Is there a way to apply withpattern to text, like fillcolor in lmt_outline[].
by ai2472206007＠yeah.net 28 Aug '24

28 Aug '24

hi , Is there a way to apply withpattern to text, like fillcolor in lmt_outline[]. what I envisaged: https://imgse.com/i/pAAkfjf I've found someone who has asked a similar question, just a combination of the two functions : lmt_outline[] and lmt_shade[] in that question. question from https://mailman.ntg.nl/archives/list/ntg-context@ntg.nl/thread/D5GBGF3RXN75… However, this example didn't work successfully on the Mac, it just showed a background color block.

Questions regarding fonts: obliques (fake italics), ligatures and kerning
by Gerion Entrup 28 Aug '24

28 Aug '24

Hi, I played around with different fonts, especially Bitstream XCharter and Overpass (http://overpassfont.org/) and wanted to combine them. However, I see some issues regarding ligatures, kerning and obliques/italics. Here is a minimal example: ``` \definefontfeature[default][mode=node, kern=yes, liga=yes] % more features % [mode=node, kern=yes, liga=yes, tlig=yes, itlg=yes, ccmp=yes, language=dflt, protrusion=quality, expansion=quality] \definefontfamily [myfont][roman][xcharter] \definefontfamily [myfont][sansserif][overpass][rscale=0.93] \definefontfamily [myfont][teletype][overpass][rscale=0.93] \definefontfamily [myfont][mono][overpassmono][rscale=0.93] \definetypeface [myfont][mathematics][math] [xcharter] \setupbodyfont[myfont, 11pt] \startTEXpage \showfontkerns Vitae, Vase, LT, VA, Y., Effizient, abcdel™, \italic{effi abcdel™}, \slanted{effi abcdel™}\\ \style[sans]{Vitae, Vase, LT, VA, Y., Effizient, abcdel™, \italic{effi abcdel™}, \slanted{effi abcdel™}}\\ \style[mono]{Vitae, Vase, LT, VA, Y., Effizient, abcdel™, \italic{effi abcdel™}, \slanted{effi abcdel™}}\\ \showbodyfont[myfont] \stopTEXpage ``` It produces the PDF in the attachment. I'm struggling with several things: - xcharter seems to have no kerning applied. It is listed as font feature, though. Is it correct to have no kerning at all for that font? - xcharter also have no ligatures (at least it doesn't look like that). That is listed as font feature, too, although only for italic and slanted. According to https://tug.org/FontCatalogue/xcharter/ there are ligatures in the font. - Overpass has a glyph for the ae ligature. Is it normal that it is not used as a ligature for ae? - Overpass Mono does not contain italic glyphs. I would have expected obliques when using \slanted then. However, it just remains normal. - I included the ™ in the example since its italic glyph is not slanted. For all fonts \slanted seems to switch to the extra (italic?) glyphs, while I would have expected obliques. At least overpass seems to have no dedicated slanted style, while xcharter has one. - Is there a command to show ligatures the same way there is a command for kerning? I attached the output of the following commands, too: mtxrun --script font --list --file --info --pattern='xcharter*' mtxrun --script font --list --file --info --pattern='overpass*' Thanks Gerion

About the font used in the document mathincontext-paper.pdf
by Fabrice Couvreur 27 Aug '24

27 Aug '24

Hello, I read this very good document and it says that it was written with the Pagella font. I use this font with a simple \setupbodyfont[pagella,11pt] but I find that the rendering is not the same as on the document, it is less nice especially in the writing of the theorems with the text in italic. Imaginary impression or reality ? Thanks. Fabrice

documenting namespaces and modules

After I got Wolfgang’s slides[1] and code example[2] from the “writing modules” workshop that I requested, I updated several wiki pages: * https://wiki.contextgarden.net/Modules * https://wiki.contextgarden.net/Module_Writing * https://wiki.contextgarden.net/Module_template * https://wiki.contextgarden.net/Module_Namespaces There are probably still errors or outdated relics left.

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

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

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

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/

How should I be compiling my for-printers file?
by Joel 24 Aug '24

24 Aug '24

I’m nearing the final stages of preparing a file for printing, which will be used to produce a textbook at a professional printer. The printer can accept PDF files, and I’ve been generating them using the context filename.tex command as part of my regular workflow. I’m wondering if this approach is producing the highest quality output for printing purposes. Is there anything additional I should consider, such as installing LuaTeX or running specific commands, or command-line switches, to ensure the best possible print quality? For context, when I installed ConTeXt standalone, it didn't seem to include LuaTeX by default, though after I installed, it asked me to run context --luatex commands which didn't function, so I worry my install isn't giving the best-possible output. --Joel

Variable counting citations

Hi there, I want to show the bibliography at the end, only when there are actually citations in this document. My attempt was to create a custom defined command to combine a citation with incrementing a counter. Is this the right way, or is there any native variable that holds the number of citations? I also want to do the same with equations. Thank you very much and kind regards, Niklas von Hirschfeld
