Metafun : reuse a static picture
by Fabrice L 24 Nov '24

24 Nov '24

Dear list, I have some difficulty to reuse a static picture in a multipage MetaFun document. I wish to define a complex image, with graphic and texts, and manipulate this image at each page. As the minimal working example shows, if I define a particular picture in the variable « AnImage » and a random text in another picture called « AnotherImage », I can use these two pictures in the first page of the document, but only one of them appears in the second page of the document (with the same code). I know that if I replace startMPinclusions/stopMPinclusions by startMPinitializations/stopMPinitializations, this works, but the image is recalculated (a different number is drawn), and I do not want this since the image is complex and takes time to make. So the question : how to make the two pictures « AnImage » and « AnotherImage » appears in the both page ? Thanks for any help ! Fabrice, % MWE : % 8< --------------------------------------- \starttext \startMPinclusions picture AnImage , AnotherImage; AnImage := image ( draw fullcircle scaled 40; ); AnotherImage := image ( arandomnumber := uniformdeviate(1); draw textext(decimal(arandomnumber)) scaled 0.5; ); \stopMPinclusions \startMPpage draw AnImage ; draw AnotherImage ; \stopMPpage \startMPpage draw AnImage ; draw AnotherImage ; \stopMPpage \stoptext % 8< ---------------------------------------

\shiftdown
by Thomas Meyer 24 Nov '24

24 Nov '24

Hi guys, I would like to move the first capital letter of a term down so that the rest of the term ends up approximately in the centre of the capital letter. The capital letter should be larger than the rest and is not a problem in itself. However, I can't manage this with \shiftdown. It always shifts down at a fixed distance. And I can't work with \setupshift. The inputs of unit=pt, dy=5 etc. don't seem to do anything, at least nothing happens with \shiftdown. Any help would be appreciated Greetings Thomas

Remove umlauts etc. from input
by Wolfgang Schuster 24 Nov '24

24 Nov '24

Hi, is there an already existing option to reduce umlauts etc. to ascii counterparts, e.g. \starttext Füße \stoptext results in Fusse The fonts manual gives an example for a font feature with the desired output but it's possible I missed something or there is a better solution. \startluacode local shapedcodes = { } for k, v in next, characters.data do local s = v.shcode if s then if type(s) == "number" then shapedcodes[utf.char(k)] = { utf.char(s) } elseif #s == 2 then shapedcodes[utf.char(k)] = { utf.char(s[1]), utf.char(s[2]) } end end end fonts.handlers.otf.addfeature { name = "simplify", type = "multiple", data = shapedcodes, } \stopluacode \definefontfeature [simplify] [simplify=yes] \starttext Füße \feature[+][simplify]Füße \stoptext Wolfgang

rfc4180splitter not handling UTF-8 with BOM files
by Marco Patzer 23 Nov '24

23 Nov '24

Hi! I run into a problem reading in certain CSV files. I nailed it down to the following example: \starttext \startluacode local mycsvsplitter = utilities.parsers.rfc4180splitter{ separator = ",", quote = '"'} -- fails with -- token call, execute: [ctxlua]:11: attempt to index a nil value (local 'tablerows') -- local mycsv = io.loaddata("A.csv") -- works local mycsv = io.loaddata("B.csv") local tablerows = mycsvsplitter(mycsv) context(tablerows[1][1]) context(" ") context(tablerows[1][2]) \stopluacode \stoptext The compilation fails with token call, execute: [ctxlua]:11: attempt to index a nil value (local 'tablerows') The two files are attached. The only difference is that: A.csv: Unicode text, UTF-8 (with BOM) text B.csv: ASCII text Somehow the rfc4180splitter chokes on UTF-8 with BOM files. io.loaddata succeeds as far as I can tell. Is there a way to read in those files without pre-processing them? Marco version: 2024.09.17 13:15

save runtime information
by Thomas A. Schmitz 20 Nov '24

20 Nov '24

Hi, a couple of years ago, I asked whether it was possible to typeset the information about runtime that I get at the end of the context run. Hans provided an answer (https://www.mail-archive.com/ntg-context@ntg.nl/msg90554.html) > it's in the log file: > > local data = io.loaddata("oeps.log") or "" > > local pattern = "> runtime: ([%d%.]+) seconds, ([%d]+) processed pages, ([%d]+) shipped pages, ([%d%.]+) pages/second" > > > local r, n, s, p = string.match(data,pattern) > > print(r,n,s,p) The information I get this way is inaccurate. The runtime (in seconds) I see at the end of the run on the terminal: 5.635 vs. the value I get with the code: 0.660260200500488 I'm not sure whether something has changed with lmtx or if this was the case before (the log file is being written to during the run, so this may explain the difference?). So my question from then still stands: is it possible to extract the real runtime somehow? I would like to write it to a different file at the end of the run. What would be the best way to do this? All best Thomas

Position of overflowing TABLE after split
by Niklas von Hirschfeld 20 Nov '24

20 Nov '24

Hi there, when having an overflowing TABLE in width (e.g. with the TABLE option 'textwidth=\dimexpr\textwidth+\rightmarginwidth\relax') the position (horizontal) changes after a split. Before the first split the table overflows into the right margin. After that the position changes and it's overflowing 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 this behavior expected? I would like the position to be the same as before the split, overflowing into the right margin, how could I achieve this. Thank you and best regards Niklas von Hirschfeld

Background colour in PDF with export activated
by Florent Michel 20 Nov '24

20 Nov '24

Hi, I'm having issues generating PDF files with a coloured background when export is set to ‘yes’. Minimal example: \setupbackend[export=yes] \setupbackgrounds [page] [background=color,backgroundcolor=black] \starttext \startcolor[white] test \stoptext This example seems to work as expected when I comment out the first line (a black page with the word ‘test’ in white). However, with the first line the pdf looks entirely white. Is this a known issue, or am I doing something wrong here? Use-case: I am trying to generate a pdf and an html files with equivalent content, the latter being primarily used for accessibility purposes. One workaround is to split the tex file in two, e;g;: % main.tex \setupbackgrounds [page] [background=color,backgroundcolor=black] \starttext \startcolor[white] test \stoptext %main-exp.tex \setupbackend[export=yes] \input{main.tex} This way, I can generate the correct pdf by compiling main.tex and the html by compiling main-exp.tex (adding a custom .css file to get a black background). But I'm wondering if there is a way of generating the correct pdf without moving the line ‘\setupbackend[export=yes]’ into a different file. Best regards, Florent

\inch not doing the expected thing (what I expect, anyway).
by Jim 16 Nov '24

16 Nov '24

Hi, I would expect (*cough*) \starttext 2\inch \stoptext to output something like 2" with some appropriate typographic symbols following the 2. Instead, I get a 2 with a large prime symbol down lower than a prime symbol should be, and then a second prime symbol at about the correct size and at about the right distance up from the baseline. Are my expectations about what \inch should do incorrect? I do notice that $2\inch$ does what I expect, but if I have to enter math mode, I may as well type $2''$ to get what I want. In summary, is \inch working as intended or it is broken? Thanks. Jim

Problem with tabulate
by Thomas Meyer 15 Nov '24

15 Nov '24

Hi Guys, I am trying out the following environment: \starttabulate[p(5mm)p(5mm)] \HL \NS[1][c] Wurfstärke R / H \NC\NR \NC 2 \NC 3 \NC\NR \HL \stoptabulate These are the columns of a larger table that cause problems. P() and \NS do not work together. But also \starttabulate[cc] \HL \NS[1][c] WurfstärkeR / H \NC\NR \NC 2 \NC 3 \NC\NR \HL \stoptabulate does not provide the desired result. Ideally, “R / H” should be under “Wurfstärke”, i.e. there should be a line break. (\\ doesn't work) Both in a combined cell. Then the numbers below should be centered in their separate cells. Something like this: Wurfstärke R / H 3 2 How can this be achieved? I am grateful for any advice. Greetings Thomas

max function in spreadsheettable
by juh+ntg-context＠mailbox.org 14 Nov '24

14 Nov '24

Dear all, I have a cell that calculates a value that may not be a negative value. If it is a negatiive value the cell should show zero. \startcell[style=normal] @ "0.2f EUR" $pauschale.eintag$ - ((D[row] * (0.2 * $pauschale.vororttag$)) + (E[row] * (0.4 * $pauschale.vororttag$)) + (F[row] * (0.4 * $pauschale.vororttag$))) \stopcell The $-variables will get resolved by Pandoc before ConTeXt comes into play. As far as I understood the handdbook spreadsheets-mkiv.pdf it is possible to define lua functions inside a cell. Who would you implement a max function that sets the value to 0 if it is negative? TIA juh P.S. For German speakers: We try to implement a Reisekostenformular.

full-width Chinese comma (U+FF0C) and ordinary comma (U+002C) in Chinese texts
by mf 14 Nov '24

14 Nov '24

Hello, I'm typesetting a bibliography with some Chinese books that have both the English translation and the original title in Chinese ideograms. The Chinese titles contain both full-width commas (U+FF0C) and ordinary commas (U+002C), followed by spaces. Full-width comma has a wide glyph that incorporates some space on the right side; I read on Wikipedia it's a mistake putting a space after it. THE PROBLEM ConTeXt does not break a line after a full-width comma (even inside a "{\cn ... }" group), while it does with an ordinary comma, followed by a space. When there are only full-width commas, sometimes I'll get overfull boxes, because ConTeXt finds no feasible breakpoints. I'm tempted to replace all the full-width commas with ordinary commas followed by a space. Is it possible, or is it a mistake? Or, how do I tell ConTeXt that breaks can occur after full-width commas?

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

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

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

How to force section title to be on same page as some of the content?

Basically it quite simply is used to define a classroom activity for students to do. Each classroom activity contains: - A subsection title. - A list of recommended materials (like scissors, glue). - Instructions directed at the student. - Where student write their answers. - A list of requirements, how it will be graded. In testing, I found students are ALWAYS very confused by page breaks: If the assignment title, supplies, and instructions appear on one page, but the area they write/body is on the next page, split there by a page break, the students think the activity is missing. They cannot find the activity. So basically, I need to make it such that items 1, 2, and 3 must appear with at least the start of 4, even if its just the first problem in 10, and even if this means leaving a blank area on the page in front of it. How can I be so precise making sure the page break doesn't seperate the title from the start of the area where students write their answers? Adding page breaks before every activity isn't a good solution, it wastes paper. --Joel

Seeking Advice on Electron Configuration Notation in ConTeXt

31 Oct '24

Hello everyone, I’m searching for an efficient way to represent electronic configurations in subshell and orbital notation within ConTeXt. I found similar examples discussed on StackExchange, which you can see here: Atomic electronic configuration with small boxes: https://tex.stackexchange.com/questions/372581/atomic-electronic-configurat… Box and arrow notation of writing electron configuration https://tex.stackexchange.com/questions/616989/box-and-arrow-notation-of-wr… Ideally, I’d like to use a package similar to atoms.sty for this purpose. Does anyone know of a straightforward approach to achieve this in ConTeXt? Thank you very much for any guidance or examples! Best regards, Jorge

Spacing issue in \digits with mode=3
by Kirill Davidov 26 Oct '24

26 Oct '24

Greetings, I have been making a table with \digits aligned cells and noticed that in mode 3 (thin mu skips as group separator, comma as decimal separator) a specification like {_X.=} causes the single digit number to be misaligned, it's like there's about 2mu worth of space just before the number. I don't have much of an idea as to what causes it. It doesn't seem to be an issue in mode 1, although it may be simply not as noticeable. This also affects \unit.

Why didn't I get the correct ordinal number, after defining an environment via command "installcounterassociation".
by ai2472206007＠yeah.net 23 Oct '24

23 Oct '24

hi, everyone I defined a command to unite counters by the method of defining counters that I saw on other posts. When I wanted to modify the start parameter of the counter, I found that it did not inherit the settings of the current environment, but inherited the settings of the previous environment. For example, in the first chapter, I set the counter for the environment to start counting from 5, but it inherited the original count of 9, and in the second chapter, it inherited the setting from the first chapter, and its counter became 5. The same happens in Chapter 3. Pls can someone fix this? Since the command to unite with the counter is what I found through previous posts and source files, I don't know exactly how it is used. If my question or the mistake I made was too stupid, be sure to let me know. Many thanks.

italian words with apostrophe - hyphenation and discretionary
by mf 23 Oct '24

23 Oct '24

Hello list, I'd like to know how to specify the following rules of the Italian language. Feminine words starting with a vowel change the preceding indefinite article ending with a vowel: the article loses the ending vowel, that is replaced by an apostrophe. Example: una opera => un'opera ("a work", but also "an opera") una opera => un’opera (with the unicode curly single quote) In case of definite articles, that is true also for masculine words starting with a vowel. la opera => l'opera ("the work", also "the opera", feminine) lo operaio => l'operaio ("the worker", masculine) This extends to articulate prepositions (preposition+article), like nella opera => nell'opera ("in the work", "in the opera") dello operaio => dell'operaio ("of the worker") HYPHENATION In Italian you can't hyphenate after an apostrophe: un'opera => un'o-pe-ra nell'opera => nel-l'o-pe-ra so these are the allowed hyphenations: un'o- pera typographically rather ugly un'ope- ra better nel- l'opera typographically the best (preposition-article split) nell'o- ugly pera nell'ope- ra but, though it's not used much anymore, you can go back to the version without apostrophe, as long as the uncut article or preposition is the last word in a line: una opera nella opera These are seldom used, but they would be a good solution, especially when the line break occurs across pages. Sometimes it's also the finest typographical solution when you have narrow columns. The reason it is seldom used is because there's no automatic solution in typesetting software. You can do it manually, but when a change in the text modifies the line breaking, the article/preposition could move away from the end of the line, and you'd get "una opera" or "nella opera" in the middle of a line, which is grammatically correct but definitely not something you would expect in a printed text, considered almost an error. THE QUESTION Is there a way to encode such rules with \hyphenation and \discretionary? I tried \hyphenation{nel{-l'o}{la}{o}-pe-ra} but it does not seem to work. Massi

changing the symbol used in \footnote{}
by David Roderick 21 Oct '24

21 Oct '24

I want to use the crucifix symbol as a footnote symbol on the title page of a book. I don't want this to increment the footnote counter. The best I can do is: \setupnotation[footnote][way=bypage, state=stop, number=†] but this does not produce any symbol at all. If I do: \setupnotation[footnote][numberconversion=set 2] then I get an asterix, not a crucifix, and I don't know how to prevent or otherwise reset the footnote counter for subsequent footnote numberings.

fake slant for definefallbackfamily

I can define fake slant for a font with \definefontfamily[mainface][rm][My Fancy Font][sl=features:slanted] How can I do it with \definefallbackfamily? According to https://wiki.contextgarden.net/index.php?title=Command/definefallbackfamily , the following should work, but it actually doesn't: \definefallbackfamily[mainface][rm][My Fancy Font][preset={range:chinese},sl=features:slanted] Besides, the wiki page lists an option `range=...` in the last bracket, but what's actually used is `preset=range:...`. Are they mistakes?

by Henning Hraban Ramm 17 Oct '24

17 Oct '24

This is lying around for years, let’s try to get it finally working. The code below works, but doesn’t do the right thing. Since the original image doesn’t contain a resolution setting, gm doesn’t do anything: “gm convert: image does not contain resolution” It would be more reliable to use “gm convert -resize”, but for that we need to know the final pixel size. How can a converter function access … – the final (scaled) size of a placed image – the original pixel size of an image ? With that information it would be easy to calculate the target pixel size. And then it would be nice to hook this function into \setupexternalfigure[conversion=] """ \startluacode local function downsampler(oldname, newname, resolution) if not resolution or resolution == "" then resolution = 72 end local cmd = string.format( [[gm convert -resample %ix%i "%s" "%s"]], resolution, resolution, oldname, newname) logs.report("downsample", cmd) os.execute(cmd) end -- Set the PDF and default JPEG converters to the above function. figures.converters.jpg.pdf = downsampler figures.converters.jpg.default = downsampler \stopluacode \setupexternalfigure[ %conversion=downsampler,% not used resolution=10, ] \starttext \externalfigure[https://upload.wikimedia.org/wikipedia/commons/d/dd/Hermann_Zapf_signing.jpg][width=.5\textwidth] \stoptext """ Hraban

Low-level macro help needed
by Rik Kabel 17 Oct '24

17 Oct '24

Hello Hans and developers, I have been trying to convert some two- and three-step macros (as shown below) to single-step macros using the LMTX syntax given in the low-level macros manual. I have succeeded in many cases, but failed when the macro follows one particular group of patterns. The group of patterns is similar to this macro to process \MyMacro[optional]{Required}{Required}{Optional} In this the number of arguments can be 2, 3, or 4. A three-step solution might be as follows, which I use for a list of persons: \defineregister[Bindex] \setupregister [Bindex][n=1, balance=no, method=default, % or New follows Newton! compress=no, % yes if not note number+q expansion=yes, pagecommand=\gobbleoneargument ] \starttexdefinition unexpanded Bi \dosingleempty\doBindex \stoptexdefinition \starttexdefinition unexpanded doBindex [#SORTAS]#INDEXED \def\SortAs{#SORTAS}% \def\Indexed{#INDEXED}% \dodoublegroupempty\doBindexFull \stoptexdefinition \starttexdefinition doBindexFull #BD#MORE \doifemptyelse{#MORE} {\Bindex[\SortAs]{\Indexed\ #BD}} {\Bindex[\SortAs]{\Indexed\ #BD\\ #MORE}} \stoptexdefinition with input like: \Bi{Rumble, Walker}{1938|–|}% \Bi{Runia, David Theunis}{1951|–|}{Classicist}% \Bi{Rutherford, Ernest (Baron Rutherford of Nelson)}{1871|–|1937}{Physicist}% \Bi{Saenger, Paul}{1945|–|}% \Bi{Saldarini, Anthony J.}{1941|–|2001}% \Bi{Salter, William M.}{1853|–|1931}% \Bi[Saint-Exupery]{de Saint-Exupéry, Antoine}{1900|–|1944}% \Bi{Santayana, George}{1863|–|1952}% \Bi{Sapir, Edward}{1884|–|1939}{Linguist}% \Bi[Schrodinger]{Schrödinger, Erwin}{1887|–|1961}{Physicist}% \Bi[Spinoza]{de Spinoza, Baruch (Benedict de Spinoza, Bento de Espinosa)}{1632|–|1677}% The best I can get with the newer syntax is a two-step: \starttexdefinition unexpanded Bi \dosingleempty\doBindex \stoptexdefinition \tolerant\def\doBindex [#1]#=#=#=% {\doifemptyelse{#4} {\Bindex[#1]{#2\ #3}}% {\Bindex[#1]{#2\ #3\\ #4}}% } In the low-level macros manual, near the end of chapter 2, it says that some day there may be a use for #?, #!, #<, or #>. If I am not missing something in the manual about how to provide that first optional argument as an empty value, I think I have one. Could [#?] always return a value (perhaps empty)? That would allow something like: \tolerant\def\doBindex [#?]#=#=#=% {\doifemptyelse{#4} {\Bindex[#1]{#2\ #3}}% {\Bindex[#1]{#2\ #3\\ #4}}% } -- Rik

Lemma in footer - some display issue
by Jean-Pierre Delange 16 Oct '24

16 Oct '24

Dear CTX users, After many months of procrastination and after discovering Ekdosis for LaTEX, I've dived back into the issues of different levels of footnotes in order to display on the first level the current notes and on the levels below the notes concerning lemmatization. Unfortunately, while I'm quite satisfied with the first page of notes, a strange phenomenon affects the lemmatization notes on the 4th page: the number of the line concerned by the lemma overwrites the last letter of the word in the lemma or in the previous lesson. I can't work out the cause of this problem. Even something like the addition of : \kern0.5em doesn't help. Does anyone have an approach that I haven't intuited? Below a MWE :

making TABLE spacing match tabulate/halign spacing

creating a printed book
by David Roderick 14 Oct '24

14 Oct '24

I have created 22 MSword files mainly text with embedded PNG diagrams. I am seeking to have these converted to Context and to redo the (simple) diagrams. I was thinking of using MetaPost. I am seeking to pay a typesetter to assist me in this task. I would be willing to pay for your time or for the time of a colleague you could direct me to. I am seeking to have typeset a book. The MSWord files have already been professionally proof-read, and the subject matter is political economy from the 18th century and how this translates to and may contradict conventional wisdom within the field of modern economics. Other typesetters I have contacted have suggested running pandoc to create a LaTeX file and use Tikz for the diagrams. But I have spent 3 days reading on advancements in the ConText side of the industry which I suspect is far more advanced. I would prefer to use better tools as a longer term solution. Can you advise me? David Roderick.

Footnote in a cell inside a row into a table !
by Jean-Pierre Delange 11 Oct '24

11 Oct '24

Dear users, I'm struggling with a bibliographic reference that I want to integrate after a name that happens to be in a cell, itself located in a table. All my code works, except for the bibliographic reference given by the footnote and the \cite command. Here's the line as it appears in my code: \startxtable[option=stretch, align={middle,lohi}, frame=off, distance=0.5em] \startxrow \startxcell \em Ambrosianus\footnote{Cf. \cite[alternative=entry][Bibliography::mai1]} \stopxcell \stopxrow \stopxtable All preliminary declarations into the file are made correctly, as is the backmatter. The PDF output is correct, but the bibliographic reference is not displayed. I seem to vaguely remember a message pointing out a similar difficulty. By coding the bibliographic reference outside the cell, the whole text display is correct, but the bibliographic reference is not displayed. I’m testing this code under Mac OSX : system > ConTeXt ver: 2022.01.06 19:51 LMTX fmt: 2022.1.7 int: English/English and I’m satisfied with the work it is doing. Any idea about what I could looking for ? Many thanks ! JP

penalties
by Henning Hraban Ramm 10 Oct '24

10 Oct '24

Yesterday I learned: \startsetups[*default] \widowpenalties 3 10000 1000 0 \clubpenalties 3 10000 1000 0 \orphanpenalties 2 8000 1000 \stopsetups If I want the penalty settings applied to “everything” (after defining the layout, I think?), then I need the setup "*defaults". Since TeX uses a club against orphans (brutal!), I’m not sure what \orphanpenalty is for. I remember \twinpenalty is against doubled words (below each other?), and \toddlerpenalty against single letter words at the end of a line (why “toddler”?). widows and clubs get only 150 in TeX, but 2000 in ConTeXt, as far as I could find. Are there more penalties that make sense to set individually? WRT demerits: Did I understand correctly that demerits are the “sum” (some formula) of badness and penalties in a line or paragraph?

widows and orphans in \definestartstop?

I have defined a simple environment for verse within prose-context. Obviously I never want the first or last lines of the verses to stand as widows or orphans.

fixing kerning and substitutions
by Florian Grammel 09 Oct '24

09 Oct '24

I am trying to reuse code of a project from 2017 with TL23 context. (Other questions probably coming up...) Back then I used font handlers to fix some smaller problems in the font, i.e. a wrongly placed small capital and missing kerning for the small caps. The following code works with context 2017.04.27 01:00 MKIV beta but has stopped having any effect using recent context (2023.05.05 18:36 LMTX). There are no error messages. Has the syntax changed? Or is the functionality dropped completely? I was also wondering why it has never been working to adjust the kerning for the regular letters, e.g. "A" and "V" in the example, neither in 2017 nor today. Thanks a lot in advance! Florian. \definefontfamily [mainface] [serif] [Palatino Linotype] [oldstyle] \setupbodyfont [mainface] %\feature[+][oldstyle] %\feature[+][kernup] %works with Context beta from 2017, doesn't work with TL 2023 \directlua{ fonts.handlers.otf.addfeature { name = "smcp", type = "alternate", data = { ['eth'] = 'Eth.ordn' , % ['k.smcp'] = 'Ķ' , }, } } %works for the smcp with Context beta from 2017, doesn't work for the regular capital letters %doesn't work at all with Context TL 2023 \directlua { fonts.handlers.otf.addfeature { name = "kern", type = "kern", data = { ["A"] = { ["V"] = 1500 }, ["P"] = { ["Æ"] = 1500 }, ["a.smcp"] = { ["s.smcp"] = 1500 }, }, } } \startdocument AVAPÆV þýðask {\sc þýðask} 123

Adding a line after the TOC

I am struggling with something that might be simple enough, but... The author is insisting that on the TOC page, after all the chapters and their page numbers, I need to add the line (obviously without any page number associated with it): 'All translations are by the author'. I have trie various combinations of \writetolist and \writebetweenlist, and I can get his comment at the beginning of the TOC, but I cannot get it at the end, and perhaps with some vertical space separation from the main list. How can I place it at the end? Here is my simple MWE where at least I can get it at the beginning: \starttochead[title={Contents}] \setcounter [userpage] [7] \setupheader[state=stop] \placecombinedlist[content] \writebetweenlist[chapter]{All translations are by the author!} \stoptochead Julian

Deactivate (back)links of the bibliography
by Gerion Entrup 08 Oct '24

08 Oct '24

Hi, when typesetting bibliographies, ConTeXt seems to link back to the (first?) citation within the text. A side effect is that the whole reference entry is colored in the link color. Is there a possibility to deactivate the back linking or limit it to the key? This is also relevant, when the bibliography contains additional URLs or DOIs that link to external resources but are not highlighted since all surrounding text is colored in the same way. Here is a MWE: ``` \setupinteraction[state=start, color=red] \startbuffer[testdata] @Book{knuth1, author = {Donald E. Knuth}, title = {TEX and METAFONT.

Small issue with \breakhere in math mode

Hi Hans and Mikael, I found a small issue in math mode with \breakhere. When \breakhere is followed by a brace in the following line, it creates a spurious break line. It can be fixed easily by the user by adding an empty line or issuing a \relax command, but I wanted to let you know. Please see the result of the following minimal example: % begin breakhere-bug.tex \starttext Compare \startformula \alignhere {\darkred c^2} = a^2 + b^2 \breakhere {\darkred z^2} = x^2 + y^2. \stopformula with \startformula \alignhere {\darkred c^2} = a^2 + b^2 \breakhere {\darkred z^2} = x^2 + y^2. \stopformula and with \startformula \alignhere {\darkred c^2} = a^2 + b^2 \breakhere\relax {\darkred z^2} = x^2 + y^2. \stopformula \stoptext % begin breakhere-bug.tex Best regards: Otared

How to improve appearance of bars in frac, sqrt, etc. on screens?
by Ralph 07 Oct '24

07 Oct '24

Hello, I’m relatively new to ConTeXt (version 2024.05.31, LMTX, standalone) and really enjoy learning it so far, but I have one little problem with the appearance of horizontal bars in math mode. It seems the way ConTeXt displayed horizontal extensible bars in math mode some time ago (as used in \frac, \sqrt, \overbar, ...) was similar to the way LaTeX (PDFLaTeX and LuaLaTeX) and Plain TeX handled this, but it has changed since then. Instead of one bar there are now multiple characters attached to each other. This makes it look more consistent with the font, but unfortunately it doesn’t display well in any PDF viewer I’ve tried (on Linux, so I’ve not tried Adobe Acrobat Reader). The bars look dotted, I guess it’s due to anti-aliasing (the dots disappear when anti-aliasing is disabled, but then of course everything looks pixelated). Two screenshots are attached (different zoom levels in PDF viewer) so that you know what I’m talking about. Source: \setuppapersize[S3] \starttext \startformula \sqrt{a^2 + b^2} = \frac{1000 \cdot c}{1000} \stopformula \stoptext Is there a way to switch to the old bars for documents viewed mainly on screens, or is there any other way to improve their appearance? I couldn’t find any documentation on this, so I would be very thankful if somebody here could help out. Best, Ralph

In principal, I would like the excurses typesetted like to solution with \defineframedtext. However, this does not work with pagebreaks. Additionally, the leftframe is too long (it begins above the "Excursus" text). I tried toffset to let the leftframe begin exactly at the "Excurses" text without success. The solution with \textbackground looks somewhat promising. It supports pagebreaks, but draws above footnotes and prints a small rectangle at the end of the excursus. I also didn't found a way to specify a leftframe only. Also, loffset seems to have no effect, here. Do I use the false environments? Do you know a better solution? Gerion

Issues with vim and lettrine modules
by Tommaso Gordini 06 Oct '24

06 Oct '24

Hi all, I'm trying to compile Axel Kielhorn's guide available here: https://github.com/AKielhorn/Context-Intro However, I get compilation errors regarding *vim *and *lettrine*. Both modules are loaded in the source files, so I typed in the terminal: mtxrun --script install-modules --install vim lettrine but the errors do not disappear. I ask you if these two modules produce known errors. In any case, the sources are available at the URL indicated above. If needed, I'll paste a MWE here in a future message. Thanks in advance Tommaso

Vertical spacing in table of content
by Gerion Entrup 06 Oct '24

06 Oct '24

Hi, for my table of contents, I have set a style that makes sections and subsections smaller than chapters. However, in the rendering the vertical space seems not to adapt: It remains equal for all entities. Is there a possibility to reduce the vertical space between subsections and sections? I tried before and after but only get it to add additional space and not reducing it. Here is a MWE: ``` \setuplist[chapter][ style=bold, aligntitle=yes, ] \setuplist[section][ aligntitle=yes, style=\tfx, ] \setuplist[subsection][ aligntitle=yes, style=\tfxx, after={\blank[none]}, before={\blank[none]}, ] \starttext \placecontent \hairline \startchapter[title=foo] \startsection[title=foo] \startsubsection[title=foo] \stopsubsection \startsubsection[title=foo] \stopsubsection \startsubsection[title=foo] \stopsubsection \stopsection \startsection[title=foo] \startsubsection[title=foo] \stopsubsection \startsubsection[title=foo] \stopsubsection \stopsection \stopchapter \startchapter[title=foo] \stopchapter \stoptext ``` Gerion

different type in footnote
by Pablo Rodriguez 05 Oct '24

05 Oct '24

Dear list, I have the following sample: \setuppapersize[A9] \starttext \type{\a.bc}\footnote{\type{\a.bc}} \stoptext Using current latest from 2024.09.25 11:53, I get an extra space after \a in the footnote. This happens both with LMTX and LuaTeX. Could anyone confirm this? (A patch would be greatly appreciated, if this were a reproducible issue.) Many thanks for your help, Pablo

Typescript font for math script and scriptscript
by juliusross＠gmail.com 04 Oct '24

04 Oct '24

Hi, I was wondering if there is a (good) way to have a specific font for sub/superscripts in mathematics that is different from the main font? I ask because I am working on a variable opentype math font, and it can be made to look a better if the superscripts are made a little bolder. Thanks in advance for any suggestions or examples. JR

Typescript and Math fallback

Dear list, I’m having some issues with my custom type-imp file. I saw in a previous exchange (https://www.mail-archive.com/ntg-context@ntg.nl/msg107516.html) that Hans suggested a way to define a fallback font for math.

how can I reset section counter when recursing buffers?

Hello, When I call a buffer with sections several times, I would like to get the same headers numbers for each buffer call.

Hi again, Besides having a solution for the mailing list server inadvertently spamming unsuspecting people through scripted form submits (see my recent message), there is also another update: the mailing lists of both ntg.nl <http://ntg.nl/> and contextgarden.net <http://contextgarden.net/> now use DKIM signing for their outgoing messages.

syntax highlighting: pandoc uses Kate
by Henning Hraban Ramm 30 Sep '24

30 Sep '24

Hi, since we recently discussed editor support and syntax highlighting: Pandoc can use definitions from Kate[1] for syntax highlighting in a code block via "--syntax-definition". There’s also ConTeXt support (MkIV/LMTX): https://kate-editor.org/syntax/data/syntax/context.xml Apparently, it can switch contexts to Lua, XML, MetaPost etc. But the list of commands is quite short. In case the author (Philipp A.) is listening: Is this intentional (“not necessary, highlight everything that starts with a backslash”)? Otherwise it probably would make sense to read in the interface files (i-*.xml). I can’t tell if it would make sense to support this syntax via a module (like scite and vim). What we have if probably enough for most of us. Hraban [1] List: https://kate-editor.org/syntax/ Specs: https://api.kde.org/frameworks/syntax-highlighting/html/

ConTeXt Journal 2022 finally online
by Henning Hraban Ramm 29 Sep '24

29 Sep '24

I just uploaded the articles from 2022: https://articles.contextgarden.net/journal/2022.html For 2023, there’s the table of contents, but as usual, we’ll wait a few months with the PDFs. (They’re already prepared.) (Thanks to Taco who did it up to 2021 and provided me with a script to simplify the task.) Hraban

first line in different font
by Thomas Meyer 29 Sep '24

29 Sep '24

Hi guys, Is it possible to set the first line of an indented paragraph in a different font? I saw it in a book. There, the first line was indented to half the line width (\setupindenting[yes, .5\textwidth]) and set in smallcaps. Any hints? Thanks in advance Thomas

Indexing redux
by Rik Kabel 28 Sep '24

28 Sep '24

Hello experts, Is there a way to generate an entry without a page number in an register that has page numbers enabled? This would enabled /See also/ entries to be generated with something like \setregisterentry[TopicIndex][keys:2=zzz,entries:1=punctuation,entries:2={{\em See also} marking}]% I do see that there is an alternative key defined for the command, but no explanation of what the alternatives are and if any would help. -- Rik

index entry with sorting and processor
by Henning Hraban Ramm 27 Sep '24

27 Sep '24

Hi again, the page number of register entries from a glossary should have a different color: \defineprocessor[glossar][color=green] \define[1]\GlIndex{\index[glossar->]{#1}} This works, but I’d like to apply a macro to the text, and then I need to set the sort order: \define[1]\GlIndex{\index[glossar->#1]{\Word{#1}}} This also works, but I get separate index entries from \index{Something} and \GlIndex{something} Glossary entries may be lowercase, but in the index I’d like to normalize to uppercase initials. (The index command is part of a lemma setup.) How can I combine the entries? I also tried \setregisterentry but didn’t find out how to use a processor for the page number. In the wiki, the (generally working) processor option is undocumented, so if there’s another option, it’s also missing. In the source, I found processors for entry & page, but not how to address the latter. MWE: """ \defineprocessor[glossar][color=green] \define[1]\GlIndex{\index[glossar->#1]{\Word{#1}}} \starttext \samplefile{ward} \index{something} \index{anything} \page \samplefile{tufte} \GlIndex{something} \GlIndex{anything} \page \placeindex \stoptext """ Hraban

Strange extra space when using cases in an inner align in math
by Gerion Entrup 27 Sep '24

27 Sep '24

Hi, I currently have the case of a strange extra space in math mode when using cases in inner align. Here is a MWE to demonstrate the problem: ``` \definemathsimplealign[inneralign] \startdocument \startformula \startalign \NC a = b \NR \NC \NC \startinneralign[n=3,align={1:right,2:middle,3:left}] \NC A \NC = \NC B \NR \NC f(x,y) \NC = \NC \startcases \NC \text{strange} \NC a \NR \NC \text{normal} \NC b \NR \NC \text{also normal} \NC b \NR \stopcases \stopinneralign \stopalign \stopformula \stopdocument ``` "strange" and "normal" are not aligned what I would expect but strange has more space in front of it. Is this a usage error or a bug in the math engine? Best, Gerion

suitable macros for Pandoc custom styles for paragraphs, spans and tables
by mf 26 Sep '24

26 Sep '24

Hello list, I started a topic in Pandoc discussions (see https://github.com/jgm/pandoc/discussions/10208) about custom styles in pandoc tables. This is the framework: - in Pandoc, some textual elements have a "custom-style" attribute, whose value becomes the name of a paragraph or character style in DOCX, ICML or ODT when exported to those formats - e.g. when you have a Span with custom-style="myStyle" around some inline text, you'll get a character style "myStyle" in those formats - for paragraphs, it's a bit different: since they have no attributes in Pandoc, you set the "custom-style" attribute of a surrounding Div element, then all the paragraphs inside it will get that custom paragraph style in DOCX, ICML or ODT - for DOCX output you may set a "custom-style" attribute also in tables Why not using that information about custom styles for ConTeXt output too? I started from the last ones (tables), suggesting that a Table element with a "custom-style" attribute set to "myStyle" could be output in ConTeXt as: \startxtable[myStyle] (Currently, tables converted to ConTeXt by Pandoc start only with a "\startxtable" line) That's doable, because ConTeXt does not terminate with an error, when it encounters a \startxtable[myStyle] not preceded by a \definextable[myStyle]. Then JGM, Pandoc's main author, replied that it would be weird having custom styles for tables and not for spans or paragraphs in ConTeXt output. Good point. In ConTeXt, there are many ways to specify what in Word and LibreOffice are "character" and "paragraph" styles. For example, \definehighlight is suitable for character styles. Badumont, in the pandoc discussion, suggested \definestartstop; good, though you should be careful not to specify a custom style with the same name of an existing environment (e.g. "narrower"); maybe a prefix like "CS" could be a workaround, so that "myStyle" becomes "CSmyStyle", and also "narrower" becomes a less dangerous "CSnarrower". Also, in this case, Pandoc should prepend a \definestartstop[CSmyStyle] before \startCSmyStyle, otherwise ConTeXt would terminate with an error (I think this is doable in Pandoc code, anyways). (BTW, the wiki says \definestartstop is "used to define block level commands": does it mean it can't be suitable for spans of inline text in a paragraph?) Any ideas to specify paragraph and character styles? Massi

As a person with very basic LaTeX skills, no experience with programming languages and an interest in LMTX (I have been coding extremely basic LMTX), how do I properly learn LMTX as a beginner to any coded language?
by Felix 25 Sep '24

25 Sep '24

I am someone who knows very basic LaTeX (I mostly learned with YouTube videos, but I would also honestly use AI to generate some code that I wanted it to make), extremely basic LMTX, and nothing like C++ or anything that I think would be considered "proper" programming languages. I have an interest in learning the newest edition of ConTeXt, but I am not sure if there is anything that could even guide a beginner wanting to learn the newest edition of ConTeXt (I believe MKIV and LMTX are regarded as being quite different). I want to get out of the habit of using AI to make stuff for me and to truly understand LMTX, but how can I do so if I seemingly do not have much understanding of ... I'll say "coding" in general? It is sometimes hard for me to read the documentation on ConTeXt garden, and I don't understand some things, but is this due to my lack of experience of looking at documentation? I would love any advice given to me.

How to change the way one input file's data is displayed, depending on where it is in the document.
by Joel 25 Sep '24

25 Sep '24

I have some code like this--it is a very reduced minimum-working example, from 10,000+ lines of code: fileA.tex------------------------------ \datatypeA{fish}{an animal that lives in the sea} \datatypeA{bear}{a big animal with claws and fur} \datatypeA{squid}{a sea creature with many legs} fileB.tex------------------------------ \datatypeB{fish}{an animal that lives in the sea} \datatypeB{bear}{a big animal with claws and fur} \datatypeB{squid}{a sea creature with many legs} main.tex------------------------------ \datatypeA[2]{\startitemize \item #1 #2 \stopitemize} \datatypeA[B]{#1 -- #2} \define[8]\activity{ \subject{#1} #2 \startitemize \item #3 \item #4 \item #5 \item #6 \item #7 \stopitemize #8 } \define[2]\balloongame{ \activity{Balloon Toss Game}{Instructions}{scissors}{plates}{construction paper}{#1}{#2}{\input fileA} } \define[2]\fishinggame{ \activity{Fun Fishing Game}{Instructions}{scissors}{plates}{construction paper}{#1}{#2}{\input fileB} } \starttext \balloongame{balloons}{tape} \fishinggame{crayons}{glue} \stoptext Basically, I have different classroom activities, defined as macros. \balloongame gives all details to the teacher about a "Balloon Toss Game" and \fishinggame defines a "Fun Fishing Game". (code has been reduced and simplified significantly). The main issue I have is I have data being stored in filesA.tex, fileB.tex, etc. (there are often a dozen such files). Note that strangly the datasets are all identical, but a different file is called, and the only difference in the dataset is they call different macros. So "Balloon Game" pulls the list, but displays them in datatypeA format, the other game takes the same data, but its in a different file, and since the macros are different, it displays the information differently. Basically, I have tons of data files sharing basically the same information, but each one defined inside the file as using a different macro, according to how the information is to be displayed (maybe sometimes as a list, sometimes in a table, etc.) This method seems horribly inefficient. I should be able to store that data in one file, but display the data in different ways. The problem is if I use one format, like this... \datatype{fish}{an animal that lives in the sea} \datatype{bear}{a big animal with claws and fur} \datatype{squid}{a sea creature with many legs} ...how do I get that dataset to be included, but displayed in a different format each time? My thinking is perhaps constantly redefine the macro \datatype, but that seems still inefficient and prone to lead to errors in the code. Is that the best solution? Any suggestion for the most proper way to go about displaying the information from this file, but in different ways in the document? NOTE: My event code already uses 8 of the #1 #2 variables, so there's not really room to include that information there. --Joel

How to keep nested itemize group together with parent itemize item?
by Joel 25 Sep '24

25 Sep '24

I have a nested itemize list like this, with first a question, then answer: \starttext \startitemize[n] \startitem What is the color of the sky? \stopitem \startitemize[3] \startitem blue \stopitem \startitem green \stopitem \startitem red \stopitem \startitem yellow \stopitem \stopitemize \startitem What is the color of the grass? \stopitem \startitemize[3] \startitem blue \stopitem \startitem green \stopitem \startitem red \stopitem \startitem yellow \stopitem \stopitemize \startitem What is the color of the butterfly? \stopitem \startitemize[3] \startitem blue \stopitem \startitem green \stopitem \startitem red \stopitem \startitem yellow \stopitem \stopitemize \stopitemize \stoptext My copyeditor has noticed that often times a page break will appear after a question, leaving the answers, or some answers on a new page. He's requested I make sure the page breaks can only occur in front of a question, such that if a new page is needed, it places the question and answers always on the same page. Is there any way to make that happen in ConTeXt? --Joel

LMTX and PDF document form German »Bundesgesetzblatt«
by Pablo Rodriguez 23 Sep '24

23 Sep '24

Dear list, for some reason unknown to me, LMTX has problems with PDF documents comming form the German official gazzette. http://www.bgbl.de/xaver/bgbl/start.xav?startbk=Bundesanzeiger_BGBl&jumpTo=… contains one of the documents and here is a minimal sample: \setuplayout[page] \starttext \externalfigure[bgbl_Bundesgesetzblatt Teil I_2022_Nr. 20 vom 22.06.2022_bgbl122s0928.pdf] \stoptext The source above distorts the page presentation with LMTX, but it is perfectly fine with LuaTeX. Could anyone confirm the issue? Many thanks for your help, Pablo
