A few question about defining symbols and creating downarrow to illustrate function rules
by Jethro Djan 25 Nov '24

25 Nov '24

Hello, I have a few questions. 1. What is the best way to get a symbol from a font you are not using as your main? %% start MWE \starttext \definesymbol[cedis][\utfchar{“20B5}] \def\cedis{ \switchtobodyfont[dejavu]\tf\symbol[cedis] } I have GH\cedis 10.00 in my pocket \stoptext %% end MWE I tried to use \getglyph because I saw it being used in a similar way (but not with unicode characters) like this: \definesymbol[cedis][\getglyph{dejavu}{\utfchar{"20B5}}] It didn't work. 2. I would like a more robust method to create a diagram (ie., a series of input and outputs where you are then required to tell the rule of the mapping). The inputs will be up with the outputs below and a downward pointing arrow between them. %% start MWE \starttext \define[2]\xdownarrow{ \startframed[frame=off,offset=0pt,width=0.8cm] \startMPcode numeric u, w; u := .3cm; w := 2pt; pair pointX, pointY; path pointXY; pointX := origin; pointY := pointX shifted (0,-3u); draw pointX -- pointY withpen pencircle scaled .6w; drawarrow pointX -- pointY withpen pencircle scaled .6w; labeloffset := u; label.top (textext("\dm{#1}"), pointX); label.bot (textext("\dm{ #2 }"), pointY); \stopMPcode \stopframed } \startitemize[n] \item Find the rule of the mapping: \startplacefigure[location=none] \startframed[frame=off,offset=0pt,] \xdownarrow{x}{y} \hspace[big] \xdownarrow{1}{3} \hspace[big] \xdownarrow{2}{1} \hspace[big] \xdownarrow{3}{-1} \hspace[big] \xdownarrow{4}{-3} \hspace[big] \xdownarrow{5}{-5} \stopframed \stopplacefigure \startitemize[a] \item \im{y = 2x + 2} \item \im{y = -2x + 2} \item \im{y = 4x} \item \im{y = -2x + 5} \stopitemize \stopitemize %% stop MWR How can I achieve this more elegantly with better spacing and the arrow pointing to the number instead (-) for negative numbers? Regards, Jethro

Arranging sometimes adds a zero
by Max Chernoff 25 Nov '24

25 Nov '24

Hi Hans, The recent discussion of imposition reminded me of an arranging bug that I found a little while ago. MWE: \setuppapersize[A5,landscape][A4] \setuparranging[2TOPSIDE] %% Uncomment to "fix" the bug % \protected\expandafter\def\expandafter\fixedspace\expandafter{% % \fixedspace% % \setbox\scratchbox\emptybox% % } \starttext \dorecurse{4}{\samplefile{knuth}} \stoptext With this example, there is an extra page on page 2 that contains nothing but a "0" in the bottom left corner. Clearing \scratchbox before the imposition code runs seems to fix this, but I wasn't able to trace it any further. Thanks, -- Max

Due to the sheer amount of possibilities combined with my current lack of full understanding how parameters work, what would be the (simple) way to layout an existing pdf containing A5 pages in to groups of booklets different from all or 4 A4 sheets each (32 pages of the pdf) e.g. the 2*2*4 does generate a booklets containing 4 sheets with 16 pages. Is there a way to change the number of sheets to bundles of 5 or 8 ? .F

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

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

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

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
