serial letters
by Henning Hraban Ramm 11 Nov '24

11 Nov '24

How would you approach serial letters, e.g. to all members of a club? (Actually I need to send out donation receipts.) I’d like to use the letter module, since my usual letter design is using it. I can export the addresses to CSV, JSON, Lua tables or whatever or transfer them to a SQLite db. Would it make more sense to read them in Lua and combine this data with a buffer, or to write a single tex file for every letter? I know how to do the latter, but I’d like to learn a more ConTeXt-ish way. Would it make sense to use the bibliographies module?

Luametatex: nesting alignments in display math formulas
by ntg-contextmailingli.expedited080＠passmail.net 10 Nov '24

10 Nov '24

I'm test driving luametatex. My needs usually extend to expressing formulas in TLA+ using nested display math formulas. Although I have suitable templates for doing this in Mark IV, I can't reproduce these satisfactorily in luametatex. For example, here's a formula from Leslie Lamport's 2006 "Lower Bounds for Asynchronous Consensus": ~~~~~~~~~~~ transitive_reduction.tex ~~~~~~~~~~~~~ \define\lbr {\lbrace \mkern 0.9mu} \define\rbr {{}\mkern 0.9mu \rbrace} \define\∀ {∀\mkern1mu} \define\∃ {∃\mkern2mu} \startdocument \startplaceformula \startformula [split=yes, align=flushleft, margin=standard, interlinespace=1ex] \bgroup \setupinterlinespace [line=1ex] \startalign [n=1, align={left,left}] \NC \text{\it TransitiveClosure}(R) ≜ \NR \NC \quad \bgroup \setupinterlinespace [line=1ex] \startalign [n=2, align={left,left,left}, location=top] \NC \text{\sc let} \quad \NC \bgroup \setupinterlinespace [line=1ex] \startalign [n=1, align={left,left}, location=top] \NC \text{\it Dom} ≜ \lbr r[1]: r ∈ R \rbr \NR \NC \text{\it Rng} ≜ \lbr r[2]: r ∈ R \rbr \NR \NC \text{\it TC}[i ∈ ℕ] ≜ \NR \NC \quad \bgroup \setupinterlinespace [line=1ex] \startalign [n=1, align={left,left}, location=top] \NC \text{\sc if}\ i = 0\ \bgroup \setupinterlinespace [line=1ex] \startalign [n=2, align={left,left,left}, location=top] \NC \text{\sc then}\ \NC R \NR \NC \text{\sc else}\ \NC \bgroup \setupinterlinespace [line=1ex] \startalign [n=1, align={left,left}, location=top] \NC \lbr 〈d, e 〉∈ \text{\it Dom} × \text{\it Rng}: \NR \NC \quad \∃ c ∈ \text{\it Dom} ∩ \text{\it Rng}: \bgroup \setupinterlinespace [line=1ex] \startalign [n=1, align={left,left}, location=top] \NC ∧ 〈d, c〉∈ \text{\it TC}[i-1] \NR \NC ∧ 〈c, e〉∈ R \,\rbr \NR \stopalign \egroup \NR \stopalign \egroup \NR \stopalign \egroup \NR \stopalign \egroup \NR \stopalign \egroup \NR \NC \text{\sc in}\ \NC \text{\sc union}\ \lbr \text{\it TC}[i] : i ∈ ℕ \rbr \NR \stopalign \egroup \NR \stopalign \egroup \stopformula \stopplaceformula \stopdocument ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The command $ context --luatex transitive_reduction.tex produces the desired result, but $ context transitive_reduction.tex rejects the alignments and centers the lines instead. Can anyone suggest how I might adapt such nesting of alignments to luametatex?

Position of wide tables after split
by Niklas von Hirschfeld 09 Nov '24

09 Nov '24

Hi there, I need a table, which is longer than the textwidth (textwidth + rightmarginwidth + rightmargindistance) and longer than a page. I got the width with the 'textwidth=\dimexpr ...' for the TABLE and the splitting working. The problem: on the first page the positioning is exactly how I want it to be, overflowing into the right margin. But on the following pages it overflows into the left margin. Here is a minimal example: \startplacetable[location={split}] \bTABLE[option=stretch,split=yes,textwidth=\dimexpr\textwidth+\rightmarginwidth+\rightmargindistance\relax] \dorecurse{100}{ \bTR \bTD Cell 1 \eTD \bTD Cell 2 \eTD \bTD Cell 3 \eTD \eTR } \eTABLE \stopplacetable is there a way to influence this behavior? I'm currently on the version: 2024.11.01 19:19 Thank you very much Niklas von Hirschfeld

Hyphenated word in html export
by Florent Michel 08 Nov '24

08 Nov '24

Hello, Is there a way to preserve hyphenated words in the html export? When exporting a document with ConTeXt, hyphens in the middle of words seem to be replaced by soft hyphens, which are not displayed by my web browser. Minimal example: \setupbackend[export=yes] \starttext co-worker \stoptext The resulting .html file contains: <div> coworker</div> (There is apparently a soft hyphen between ‘co’ and ‘worker’. The pdf seems to render correctly.) Cheers, Florent

How can a macro check how many items are in a list?
by Joel 05 Nov '24

05 Nov '24

Suppose I have a macro like this: \define[1]\thisismylist{ This list has n items. \startitemize #1\stopitemize } And in the document it might have this: \thisismylist{\item cat\item dog\item tree } How can I make n display three, as there are three items? "This list has 3 items: 1. cat2. dog3. tree I will use this as a means to check if the description before a list needs a plural or not: Read the prompts below: - Do you think cats should be banned from university dormitories?- Should public schools provide free breakfast? And that way, if there is only one prompt, it changes the instructions to be: Read the prompt below: - Do you think cats should be banned from university dormitories? --Joel

Expected behaviour of \definelayout
by louis.ad＠hotmail.ch 05 Nov '24

05 Nov '24

Hello, I am new to ConTeXt and was trying to understand whether the following behaviour of \definelayout is expected. Consider this example, > \setuplayout[grid=yes] > \showgrid > \definelayout[odd][ > backspace=50mm, > width=90mm, > topspace=20mm, > header=0mm, > footer=0mm, > height=250mm, > ] > > \starttext > \showframe > \dorecurse{10}{\input knuth } > \stoptext which I compile with `context example.tex` (ConTeXt Process Management 1.06, current version: 2024.02.27 09:18, obtained via TeXLive 2024). While the document's layout updates on page 2 (at least, what's being shown by \showframe), the text is typeset using the previous (page 1) layout until it encounters the next \par. This repeats on the transition from page 2 to 3. I have tried to look for an answer in the following texts to no avail, - The layout guide: "It's in the details" - The "ConTEXt Mark IV: an excursion" - The mailing list: Peter Hopcroft chimed in with a similar issue in Dec 2022 (which I did not manage to replicate; it appears the solution was to enforce paragraphs at the layout change?) Is this just the expected behaviour of the layout engine or am I missing something in my preamble? I would very much appreciate your insights, thank you in advance! Louis

What is the current correct way to load fallback fonts?
by Joel 05 Nov '24

05 Nov '24

I am using EB Garamond for my font, but there's a few places I need some special characters, like a checkmark symbol, so I'm trying to set FreeSerif as a fallback. \definefallbackfamily[main] [serif] [file:/home/joel/.fonts/FreeSerif.otf] [range=dingbats, force=yes] \definefallbackfamily[main] [sans] [file:/home/joel/.fonts/FreeSerif.otf] [range=dingbats, force=yes] \starttypescript[serif] [garamond] \definefontsynonym[Serif] [file:/home/joel/.fonts/EBGaramond-Regular.otf] \definefontsynonym[SerifBold] [file:/home/joel/.fonts/EBGaramond-Bold.otf] \definefontsynonym[SerifItalic] [file:/home/joel/.fonts/EBGaramond-Italic.otf] \definefontsynonym[SerifBoldItalic] [file:/home/joel/.fonts/EBGaramond-BoldItalic.otf] \definefontsynonym[SerifCaps] [file:/home/joel/.fonts/EBGaramond12-AllSC.otf] \stoptypescript % \starttypescript[sans] [garamond] \definefontsynonym[Sans] [file:/home/joel/.fonts/OptimaLTStd-Bold.otf] \definefontsynonym[SansBold] [file:/home/joel/.fonts/OptimaLTStd.otf] \definefontsynonym[SansItalic] [file:/home/joel/.fonts/EBGaramond-Italic.otf] \definefontsynonym[SansBoldItalic] [file:/home/joel/.fonts/LeMurmure-Regular.otf] \definefontsynonym[SansCaps] [file:/home/joel/.fonts/EBGaramond12-AllSC.otf] \stoptypescript % \starttypescript[garamond] \definetypeface[garamond] [rm][serif][garamond][default] \definetypeface[garamond] [ss][sans][garamond][default] \definetypeface[garamond] [mm][math][math][default] \stoptypescript % I've looked through many handbooks and old questions on-line and tried many configurations. It appears the way to define the fallback has changed many times over the years, and none I've tried works. I've confirmed I can make ConTeXt use my font "FreeSerif.otf", but I can't get it to appear as a fallback. Basically if the character can't be found in EB Garamond, I hope it will use FreeSerif.otf, but generally, I'm just using it for a couple special symbols. How do I correct his so it properly displays the symbols from FreeSerif.otf? --Joel

penalties
by Thomas Meyer 05 Nov '24

05 Nov '24

Hi folks, following today's update, \startsetups[grid][mypenalties] \setdefaultpenalties \setpenalties\widowpenalties{2}{10000} \setpenalties\clubpenalties {2}{10000} \stopsetups \setuplayout[grid=yes, setups=mypenalties] doesn't work any longer, I think. Can anyone confirm this. There is another problem (page break in the paragraph) that I have yet to verify. Greetings Thomas

compact fonts, fake slanted and \definefallbackfamily (LMTX only)
by Pablo Rodriguez 04 Nov '24

04 Nov '24

Dear list, I have the following sample: \enableexperiments[fonts.compact] \definefallbackfamily [mainface][rm][Dejavu Sans] [sl={style:regular, features:slanted},preset=range:greek] \definefontfamily [mainface][rm][Latin Modern Sans] %[sl={style:regular, features:slanted}] \setupbodyfont [mainface] \starttext αβγ9 some word others\\ \sl αβγ9 some word others \stoptext The only way to get slanted Greek is either not to enable compact fonts or to add fake slanted to \definefontfamily. I’m experiencing this with LMTX only (MkIV is fine). I’m using current latest (2024.11.01 19:19). Could anyone confirm the issue? Many thanks for your help, Pablo

Hi, With the below, the overbraces appear too high (the underbraces are in the right position) \starttext \switchtobodyfont[concrete] \startformula \overbrace{a+a} \underbrace{a+a} \stopformula \stoptext Would appreciate if somebody can tell me if they see the same, or if this is a bug. The version of ConTeXt I use is below. Thanks!
