Macro to write a letter with \ mathscript{}
by Fabrice Couvreur 18 Apr '21

18 Apr '21

Hi, This is going to be difficult to explain because the code below works but in a project with many components does not. Actually the macro does not work in the definition environment in my project but in the same environment of this simple code yes. Thank you for your possible help. Fabrice \setupbodyfont[modern] \setupenumerations [before={}, after={\blank}, alternative=serried, number=no, title=yes, titleleft={(}, titleright={)}, prefix=yes, prefixsegments=chapter, way=bychapter, titlestyle=bold, width=broad] \defineenumeration [definition] [text=Définition, number=no, headcommand=\groupedcommand{}{}, style=slanted] \setupmathematics[stylealternative=calligraphic] \unexpanded\def\CScript#1#2{\start\switchtobodyfont[stixtwo]\m{{\mathscript{#1}}_{#2}}\stop} \unexpanded\def\cscript#1{\start\switchtobodyfont[stixtwo]\m{{\mathscript{#1}}}\stop} \starttext \startdefinition \placefigure[right]{}{ \startMPcode path rectangle; rectangle=unitsquare xscaled 6cm yscaled 4cm; draw rectangle withcolor green; label.bot("\cscript{C}", center rectangle); \stopMPcode} Soit \m{f} une fonction continue et positive sur un intervalle \m{[a\,;b]} et \cscript{C} sa courbe représentative dans un repère orthogonal.

Verbose numbers in swedish
by peter kvillegard 17 Apr '21

17 Apr '21

Hi, I'm trying to get verbose numbers (i.e. "five" instead of 5) to work when \mainlanguage[sv] is set. I'm new to ConTeXt so I'm still struggling to grasp how everything fits together, but I found the spanish verbose numbers in core-con.lua, and added functions for swedish to match that which seemed relevant. I'm attaching my core-con.lua if that helps. (My additions start at line 1418) My question is, are there more places in other files that also need to be modified for this to work? If so, I would be grateful if you could point me in the right direction. There must be some step that I'm missing. Thank you. MWE where I expect the word "ett" instead of "1": \mainlanguage[sv] \starttext \convertnumber{words}{1} \stoptext

register for biblical citations
by jbf 17 Apr '21

17 Apr '21

I am wondering if anyone has had to set up a register (index) for biblical citations, where the order is not alphabetical but the order of the biblical books themselves, so, for example, citations from Genesis (e.g. Gen 1:1; Gen 6:4; Ex 15:2; Deut 12:8 etc. etc). I am not at all sure how to achieve this. Julian

autopdf on MacOS?
by Hans van der Meer 16 Apr '21

16 Apr '21

When running the command: context --autopdf --run myfile.tex I had hoped the pdfviewer Preview on my MacOS system (version Catalina) would open the pdf for viewing. Allthough a new pdf is created, this is not opened. If the pdf is open in Preview already, it is not updated unless switching to the Preview application. It something wrong here? Is it not functional in MacOS? Am I missing some clue? met vriendelijke groet dr. Hans van der Meer

lmtx goodies
by Hans Hagen 15 Apr '21

15 Apr '21

Hi, I'm checking out some old experiments (either use or drop 'm) and here's one that made it into lmtx in the end (not much code). We have a bunch of arrays in the engine: \uccode, \lccode, \sfcode, \efcode, catcodes etc and while traditional tex just has 256 slot arrays in luatex these are sparse: it saves memory because often these lists cover a small range of unicode. Because this is kind of a general mechanism, I've added a lua interface to 'user sparse arrays' shown in the following examples (they can be 1, 2 or 4 bytes numbers): \setuplayout[tight] \setupbodyfont[tt,10pt] \starttext \startluacode local d = io.loaddata(resolvers.findfile("tufte.tex")) local a = sparse.new() for v in string.utfvalues(d) do -- sparse.set(a,v,sparse.get(a,v)+1) a[v] = a[v] + 1 end for i, v in sparse.traverse(a) do if i > 32 and v > 0 then context("%03i %U\\crlf",i,i) end end \stopluacode \blank \startluacode local a = { } local y = string.byte("1") local n = string.byte("0") for i=1,20 do a[i] = sparse.new(1,n) -- bytes (1|2|4) | default end for i=8,15 do local ai = a[i] for j=10,15 do -- sparse.set(ai,j,y) ai[j] = y end end for i=1,20 do a[i] = sparse.concat(a[i],1,20) end context(table.concat(a,"\\crlf")) \stopluacode \blank \codedef\mycode { \mycode 999 = 123} 000 = \the\mycode999\par {\global\mycode 999 = 124} 124 = \the\mycode999\par { \mycode 999 = 125} 124 = \the\mycode999\par \stoptext Often using a lua array or hash is more efficient, but when you allocate many real large sets the sparse arrays might win. I can add more options at the tex end, like wipe, concat, prealloc, save, load, always global etc. but that depends on expected usage of which I have no clue (but as usual with tex features, at some point they will be used in unexpected ways).

Sudoku module
by Jairo A. del Rio 12 Apr '21

12 Apr '21

Hi, list! I've just finished a minimal module for sudoku puzzles based on Peter Norvig's algorithm. The module and examples are in the link below: https://github.com/JairoAdelRio/context-sudoku My port is a sorta literal translation of Python's version, so improvements are to be done. As always, I'm having trouble passing color data from TeX to Lua so that sudokus have more customizable aesthetics. I'll gladly accept any feedback and recommendations before I submit the module to the Garden. Thank you very much. Stay safe. Jairo
