Thank you Hanks, seems to work well after some tweaking. I had an issue, the patch you sent me gave an error when I ran 'context --make'. The error said: tex error > tex error on line 51 in file core-dat.mkxl: Parameters must be numbered consecutively [#1]#*[ <to be read again> S <line 3.51> \permanent\tolerant\protected\def\setdataset[#1]#*[#S #2]#*[#S#3]% <empty file> I've inserted the digit you should have used after the #. I edited line 51 as: \permanent\tolerant\protected\def\setdataset[#1]#*[#2]#*[#3]% Instead of your original: \permanent\tolerant\protected\def\setdataset[#1]#*[#S#2]#*[#S#3]% And now context --make runs, and the example compiles correctly, however, not really sure if what I did was the right thing to do.

new upload
by Hans Hagen 17 Aug '23

17 Aug '23

Hi, I uploaded a new lmtx (some new - experimental - things will be explained after the ctx meeting), but there's one thing that is somewhat important. In addition to the built in units we can now have so called user units. There is some more info about this in the lowlevel-registers manual. One of the predefined units is 'uu' with an associated \ununit (dimension) variable and it's is also interfaced to metafun. That means that when you use uu in metapost graphics you have to make sure that you save the meaning and/or numeric uu now. The idea is that just as in mp one can say 20xx with xx being a (sort of) unit, one can do the same in tex. Think of \newdimension \MyUnitA \MyUnitA 1.23pt \pushoverloadmode % just in case \newuserunit\MyUnitA ua % binds the unit to the variable \popoverloadmode x\hskip 10ua\relax x The units starting with 'u' are considered user units but be carefulk with other combinations as we have (and will have more) built into context ones, like pi : pi for Mikael ft : foot for Alan fs : (global body) font size tw : (layout) text width th : (layout) text height hs : (current) hsize vs : (current) vsize cd : (when set) column distance cw : (when set) column width cx : combination cell width uu : user unit (\METAFUN) So Mikael can now have test \hskip 3pi\relax test and Alan can have \setuplayout [width=1ft] to be consistent with inches. The reason why we have this mechanism is that it provides a level of abstraction. It might evolve over time but don't expect the 600+ units possible to show up because one needs sensible shortcuts. Already built in unit always win and you cna only bind to already defined quantities. Here's one for those who want to go beyond the normal: \newdimension \FooA \FooA 1.23pt \newdimen \FooB \FooB 12.3pt \protected\def\FooC {\the\dimexpr\FooA +\FooB\relax} So you can now figure how 'cx' is defined in a dynamic way.

Optical scaling in Latin Modern
by Hamid,Idris 17 Aug '23

17 Aug '23

Dear gang, It seems that ConTeXt does not currently implement optical scaling for Latin Modern -- at least not by default. For example: ======= \startTEXpage[offset=1em] Test {\tfa Test} {\tfb Test} {\tfc Test} {\tfd Test} {\tfx Test} {\tfxx Test} \stopTEXpage ======= In the log we have ======= mkiv lua stats > loaded fonts: 2 files: latinmodern-math.otf, lmroman10-regular.otf ======= Is this behavior intentional? The needed sizes are certainly available (/texmf/fonts/data/gust/lm). This issue came up while trying to test/implement something else. Although Computer Modern / Latin Modern is perhaps hardly popular for contemporary publication work, a full implementation of the full palette of optical sizes is still useful as a benchmark, etc. Best wishes Idris -- Professor Idris Samawi Hamid Department of Philosophy Colorado State University Fort Collins, CO 80523

Experiments with \doloopoverlist

Hello List. I've been trying to typeset a somewhat complex list of authors for several articles and a book. My proof of concept seems to work fine, however, I know I am doing weird things that I think could probably be done in a better way. I'm using datasets and a recursion, kind of hacky but I can't find a better way of handling it. Specifically I would like to know: 1. Is there a way of getting the length of a filled dataset? (how many entries it contains) 2. Is it OK to use \startuserdata \stopuserdata without its inlineuserdata? Is there an alternative that does not require inlineuserdata? %%%%%%%%%% MWE: \setupinteraction[state=start] \define[2]\imghref{\bgroup\goto{#1}[url(#2)]\egroup} \defineexternalfigure[logo][height=1em] \definedataset[autores] \setdataset[autores][ nombre={Angie Natalia Farfán Acevedo}, cvlac={ https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do… }, orcid={https://orcid.org/0009-0007-0765-4241}, gscholar={ https://scholar.google.com/citations?user=GpYTTU0AAAAJ&hl=es&authuser=1}, ] \setdataset[autores][ nombre={Ivon Andrea Rodríguez Román} cvlac={ https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do… } orcid={https://orcid.org/0009-0001-1183-6829} gscholar={https://scholar.google.com/citations?user=iz8SQNcAAAAJ&hl=es} ] \setdataset[autores][ nombre={Angie Caterin Garzón González} cvlac={ https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do… } orcid={https://orcid.org/0009-0009-0990-6902} gscholar={ https://scholar.google.com/citations?view_op=list_works&hl=es&user=5WqcOeEA… } ] \setdataset[autores][ nombre={Heidy Paola Veira Tenorio} cvlac={ https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do… } orcid={https://orcid.org/0009-0008-4076-7317} gscholar={ https://scholar.google.es/citations?view_op=new_profile&hl=es&authuser=1} ] \setdataset[autores][ nombre={Yerly Lorena Diaz Aldana} cvlac={ https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do… } orcid={https://orcid.org/0009-0008-1720-4057} gscholar={ https://scholar.google.com/citations?hl=es&user=0obyCwkAAAAJ&view_op=list_w… } ] \defineuserdataalternative[idautor][renderingsetup=userdata:idautor] \startsetups[userdata:idautor] \dontleavehmode \imghref {\externalfigure[cvlac.pdf][logo]} {\userdataparameter{cvlac}} \quad \imghref {\externalfigure[orcid.pdf][logo]} {\userdataparameter{orcid}} \quad \imghref {\externalfigure[gscholar.pdf][logo]} {\userdataparameter{gscholar}} \quad \userdataparameter{author}\par \stopsetups \defineuserdata[idautor][alternative=idautor] \startdocument % I have to manually set the length of the dataset in the loop and use recurselevel... % Maybe there is a way to use the length of the "autores" dataset? and use indexes? \dorecurse{5}{ \startuserdata[idautor][ author={\datasetvariable{autores}{\recurselevel}{nombre}}, cvlac={\datasetvariable{autores}{\recurselevel}{cvlac}}, orcid={\datasetvariable{autores}{\recurselevel}{orcid}}, gscholar={\datasetvariable{autores}{\recurselevel}{gscholar}}, ]\stopuserdata % My "inlineuserdata" is empty... no idea if this is OK... } \stopdocument %%%%%%%%%% END MWE Thank you in advance. -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

disable header for endnotes
by jbf 16 Aug '23

16 Aug '23

I wonder if someone might be able to help me with this. I have a book in three parts and the author wants endnotes. No problem. I can produce those with \setupfootnotes[location=text] and then \placefootnotes. However, I would like the header to read 'Notes' on the recto page (or indeed be blank with no header), but I am currently getting the header that belongs to the main setup for headers, which happens to be: \startsetups[middle] \hfill \getmarking[section] \hfill \stopsetups \setupheadertexts [{\hfill\documentvariable{metadata:title}\hfill}][] [\setups{middle}][] How do I deal with the \placefootnotes command so that it ignores this and either gives me no header, or perhaps a new header with 'Notes' in place of [section] (which is achieved in centered position with setups[middle])?

itemize
by Hans Hagen 15 Aug '23

15 Aug '23

Hi, There has been some additions to itemize wrt columns. One problem with columns is that we have a 'cross page' and 'balancing' situation. The existing columns features has been improved a bit. That leaves the problem that mixing single and multi columns is not really tex's strong point. So, when Mikael and I were looking at one of his documents that mixes a lot of math into itemized situations, a different variant was made (ok, there was another reason but that's a bit technical). At that time, I had already adapted itemize to work a bit better with bTABLE and starttabulate (nesting, trial mode etc), think of \bTABLE \bTR \bTD \startitemize[a] \startitem \im{\sqrt{\frac{1}{x^4}}} \stopitem \startitem \startitemize[n] \startitem \im{\sqrt{\frac{1}{x^4}}} \stopitem \startitem \im{\sqrt{\frac{1}{x^4}}} \stopitem \stopitemize \stopitem \startitem \im{\sqrt{\frac{1}{x^4}}} \stopitem \stopitemize \eTD \eTR \eTABLE or with tabulate \startitemize[n] \starttabulate[||k2|] \NC \startitem test \stopitem \NC \startitem test \stopitem \NC \NR \NC \startitem test \stopitem \NC \startitem test \stopitem \NC \NR \stoptabulate \stopitemize so basically inside these tables items can be dealt with. Don't wonder too much how this translates into structure. So, back the columns, a logical next step was to add tabulated columns to itemize: \startitemizetable[n,four] \dorecurse{10}{ \startitem \im{\sqrt{\frac{1}{x^4}}} \stopitem \startitem \im{\sqrt{x^5}} \stopitem \startitem \im{\frac{x^5}{x^5}} \stopitem } \stopitemizetable or with \defineitemgroup[xxxx] because every itemgroup also gets an additional pair of commands defined. \startxxxxtable[n,four][inbetween={\blank[big]}] \dorecurse{10}{ \startitem \im{\sqrt{1/x}} \stopitem \startitem \im{\sqrt{\frac{2}{x}}} \stopitem \startitem \im{\frac{3}{x}} \stopitem } \startitem \im{\sqrt{\frac{1}{x^4}}} \stopitem \startitem \im{\sqrt{x^5}} \stopitem \stopxxxxtable etc etc. The distance can be set with columndistance and vertical spacing with inbetween. This kind of columnizing has the advantage that esp with math that has different heights all aligns rather well. A limitation is that we number horizontally but that actually makes sense when we cross pages (I might cook up a transposed numbering but it's not entirely trivial). The first one who uses this other than Mikael is invited to wikify it. Hans ps. The page columns also have some improvements but that's for next month. ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Pass string into text background graphic
by Thangalin 13 Aug '23

13 Aug '23

Hi list, I'm attempting to make a stylized border around paragraphs that can span pages. The border runs along the side and the top. (Ideally the top border wouldn't repeat, but that's a minor issue.) The issue I'm having is that the title for the text doesn't always appear. Instead, there's a small gap along the top border where the title should be. Am I going about this the wrong way? % SOT \startbuffer[demo] <html> <body> <div class="concurrent" data-title="Berth 5" data-location="San Diego"> Text Goes Here </div> <div class="concurrent" data-title="Road" data-location="Beale AFB"> Different Text Goes Here </div> </body> </html>\stopbuffer \startxmlsetups xml:xhtml \xmlsetsetup{\xmldocument}{*}{-} \xmlsetsetup{\xmldocument}{html|body}{xml:*} \xmlsetsetup{\xmldocument}{div}{xml:*}\stopxmlsetups \xmlregistersetup{xml:xhtml} \startxmlsetups xml:html \xmlflush{#1}\stopxmlsetups \startxmlsetups xml:body \xmlflush{#1}\stopxmlsetups \startxmlsetups xml:div \setvariable{div}{\xmlatt{#1}{class}}{#1} \start[\xmlatt{#1}{class}]\xmlflush{#1}\stop\stopxmlsetups \startusableMPgraphic{GraphicConcurrent} begingroup; string legend; picture title; picture border; picture bg; numeric tw; numeric th; legend := \MPstring{concurrent}; title := nullpicture; border := nullpicture; bg := textext( "\strut " & legend ); tw := xpart lrcorner bg - xpart llcorner bg; th := ypart ulcorner bg - ypart llcorner bg; addto title also image( fill unitsquare xysized (tw + 8, th) shifted ulcorner multipars[1] shifted 28 right shifted 8 down withcolor white; draw textext.drt( legend ) shifted ulcorner multipars[1] shifted 32 right shifted 3 down; ); addto border also image( for i = 1 upto nofmultipars: draw llcorner multipars[i] -- ulcorner multipars[i] shifted 8 down .. ulcorner multipars[i] shifted 8 right -- urcorner multipars[i] withpen pencircle scaled 0.75 withcolor black; endfor; ); draw image( draw border; draw title; ); endgroup;\stopusableMPgraphic \definetextbackground[TextConcurrentFrame][ mp=GraphicConcurrent, frame=off, topoffset=1em, leftoffset=1em, location=paragraph, ] \definestartstop[concurrent][ before={% \blank[big]% LEGEND: \xmlatt{\getvariable{div}{concurrent}}{data-title}% \blank[big]% \setMPtext{concurrent}{\xmlatt{\getvariable{div}{concurrent}}{data-title}} \startTextConcurrentFrame}, after={\stopTextConcurrentFrame\blank[big]}, ] \starttext \xmlprocessbuffer{main}{demo}{}\stoptext % EOT If I change the following line: legend := \MPstring{concurrent}; to: legend := "some string"; Then the title "some string" is repeated. It seems like the value for \MPstring{concurrent} is being cached in some situations and ignored in others. Essentially, I'm trying to visually offset multiple paragraphs using a left-hand vertical rule along with a top horizontal rule that has a title. Each new "concurrent" section needs its own header that doesn't repeat. Is there a ConTeXt-way to accomplish this feat? Cheers!

side-by-side paragraphs broken?
by Thomas A. Schmitz 13 Aug '23

13 Aug '23

Hi, in more recent versions of lmtx, the side-by-side mechanism appears to be broken; example below. The right-hand paragraph does not respect the margin and backspace setting. The output looks fine in mkiv and with older versions of lmtx (the one from texlive, so 2023.03.10). Not sure if this has been reported yet. All best Thomas \setuppapersize[A4,landscape] \setuplayout[height=fit, width=middle, header=0cm, footer=0cm, leftmargin=2cm, topspace=1.2cm, backspace=1.5cm] \showframe \defineparagraphs[Half] [n=2] \setupparagraphs [Half] [before=,after=,distance=3em,align={normal,hanging},tolerance={stretch,verytolerant}] \setupparagraphs [Half] [1] [width=0.43\textwidth,tolerance={stretch,verytolerant}] \setupparagraphs [Half] [2] [rulethickness=2mm,rulecolor=gray,rule=on,tolerance={stretch,verytolerant}] \starttext \startHalf \input ward \nextHalf \input knuth \stopHalf \stoptext

Font switching, default features, and a request
by Hamid,Idris 13 Aug '23

13 Aug '23

Dear gang, Consider the following example: ============== \setupdirections[bidi=global,method=one] \startTEXpage[offset=1em,width=14in] \definedfont[almfixed*arabic] \switchtobodyfont[almfixed*arabic] \switchtobodyfont[almfixed] % \addff{arabic} \startbuffer[] \startlines الثَّعْلَبُ الْأَسْمَرُ السَّرِيعُ يَقْفِزُ فَوْقَ الْكَلْبِ الْكَسُولِ! The quick brown fox jumps over the lazy dog! \stoplines \stopbuffer {\tfxx \type{\tfxx} \getbuffer} {\tfx \type{\tfx} \getbuffer} \type{\tf} \getbuffer {\tfa \type{\tfa} \getbuffer} {\tfb \type{\tfb} \getbuffer} {\tfc \type{\tfc} \getbuffer} {\tfd \type{\tfd} \getbuffer} \stopTEXpage ============== There are three font switches to choose from: ============== \definedfont[almfixed*arabic] \switchtobodyfont[almfixed*arabic] \switchtobodyfont[almfixed] ============== Let's toggle one at a time: 1) \definedfont[almfixed*arabic] a) gives us the correct bidi output, but only for the \tf size b) is ignored for every other size switch. a) and b) are expected behavior. 2) \switchtobodyfont[almfixed] a) gives us Arabic-script bidi output, b) exhibits no Arabic-script features c) gives the same result for each size switch This means that the fontfeature "arabic" -- already predefined in ConTeXt (font-pre.mkiv) -- is not explicitly applied. Curiously, invoking \addff{arabic} does not affect the output. Why is it that \addff{arabic} does not work here? 3) \switchtobodyfont[almfixed*arabic] suppresses the font entirely and we're back to Latin Modern for all sizes. Assuming that this is expected behavior, it appears to follow that fontfeatures cannot be invoked for \switchtobodyfont and the like, only from within the typescript read by \switchtobodyfont etc. ======= REQUEST: Since ALMFixed is already distributed with ConTeXt, could Hans make the fontfeature "arabic" default for this font? That is \switchtobodyfont[almfixed] should automatically a) give us Arabic-script bidi output (already there), b) exhibit Arabic-script features (missing) c) gives the same result for each size switch (already there) (Indeed, it would be useful to have *arabic-predefined typescripts/bodyfonts for a few other commonly available/used Arabic fonts as well. Would be willing to make a list at some point, test, etc.) Thank you in advance for considering this request.

Scaling characters without font switching in CLD
by Hamid,Idris 13 Aug '23

13 Aug '23

Dear gang, I. In Context, as is well known, scaling a character is not independent of switching the font: ======= \startTEXpage[offset=1em] \definefont[Times][times @ 14pt] \Times Test \tfx Test \setupinterlinespace \Times Test \switchtobodyfont[x]Test \Times Test \high{Test} \stopTEXpage ======= \tfx causes a switch to computer modern. Of course, with the right typescripts and \setupbodyfont, one can maintain stylistic consistency when switching fonts. But what if we want to scale independently of font switching? II. One approach might be to use symbols: \startTEXpage \definesymbol[Tee][\getglyph{times}{T}] \symbol[Tee]est \tfx \symbol[Tee]est \tfa \symbol[Tee]est \stopTEXpage In this example, \tfa does scale the symbol Tee. But \tfx does not scale the symbol! Why does \tfa (or higher such as \tfb etc.) work, but not \tfx (or lower)? III. The best approach would be to do it in CLD (Context Lua Code). That is mostly beyond my skill to write from scratch without a template, but there are some experiments in the system file font-imp-effects.lua. There we will find, e.g., local specification = { name = "extend", description = "scale glyphs horizontally", initializers = { base = initializeextend, node = initializeextend, } } local specification = { name = "squeeze", description = "scale glyphs vertically", initializers = { base = initializesqueeze, node = initializesqueeze, } } This seems hopeful: \definecolor [transparentgreen] [g=1,t=.7,a=1] \definecolor [transparentred] [r=1,t=.7,a=1] \definecolor [transparentyellow] [y=1,t=.7,a=1] \startTEXpage[offset=1em] \definefontfeature[scale][default][extend=yes,squeeze=yes] \hbox{\rlap{\definedfont[times @ 14pt]\transparentgreen Test}% \definedfont[times*scale @ 14pt]\transparentred Test} \stopTEXpage But there is no scaling of the character, extend=yes shifts the glyphs to the left, and squeeze=yes appears to do nothing at all. Here is a file collecting these experiments: https://www.dropbox.com/scl/fi/dggj3ypgjjeia1bo4eelb/test-scaling.tex?rlkey… https://www.dropbox.com/scl/fi/o2u1tsq515ycyoeup43qg/test-scaling.pdf?rlkey… IV. Objective: I need to be able to define a couple of characters in CLD -- glottal stops --, and add commands to scale and/or rotate a character without triggering a font switch. Again, writing this from scratch is beyond my current skill set - although I've recently started to study CLD. Something like this -- some of the semantics is almost certainly wrong and/or clumsy -) ============== -- ʿ ringhalfleft local function ringhalfleft (characters,target,base,accent) -- if not characters[target] then local data1 = characters[base] local data2 = characters[accent] if data1 and data2 then characters[target] = { -- "ʿ" height = data1.height, depth = (data1.depth or 0) + 0.5*(data2.height or 0), width = data1.width, unicode = target, commands = { { "slot", 0, 0 }, { "left", -0.5*(data2.width or 0) + 0.5*(data2.width or 0)}, -- { "down", 0.2*(data2.height or 0) + (data2.height or 0) }, { "up", 0.0*(data2.height or 0) + (data2.height or 0) }, { "slot", 0, 0x063, }, { "squeeze", 0.75*(data2.height or 0) }, { "extend", 0.75*(data2.width or 0) }, }, } end -- end end -- ʾ ringhalfright local function ringhalfright (characters,target,base,accent) -- if not characters[target] then local data1 = characters[base] local data2 = characters[accent] if data1 and data2 then characters[target] = { -- "ʾ" height = data1.height, depth = (data1.depth or 0) + 0.5*(data2.height or 0), width = data1.width, unicode = target, commands = { { "slot", 0, 0 }, { "left", -0.35*(data2.width or 0) + 0.5*(data2.width or 0)}, { "down", 0.0*(data2.height or 0) + (data2.height or 0) }, -- { "up", 0.0*(data2.height or 0) + (data2.height or 0) }, { "slot", 0, 0x063, }, { "squeeze", 0.75*(data2.height or 0) }, { "extend", 0.75*(data2.width or 0) }, }, } end -- end end local function initialize(tfmdata,value) if value then -- Hdotbelow(tfmdata.characters,0x02BF,0x063,0) -- ringhalfleft (tfmdata.characters,0x02BF,0x063,0x063) ringhalfright(tfmdata.characters,0x02BE,0x063,0x063) -- (i.e., tfmdata.characters,target,base,accent) -- hdotbelow(tfmdata.characters,0x1E25,0x068,0x2D9) end end local function scale (ringhalfleft,ringhalfright) for v in next, ringhalfleft do v.height = 0.75 * (v.height or 0) v.width = 0.75 * (v.width or 0) v.depth = 0.75 * (v.depth or 0) end for v in next, ringhalfright do v.height = 0.75 * (v.height or 0) v.width = 0.75 * (v.width or 0) v.depth = 0.75 * (v.depth or 0) end end local specification = { name = "glottalstops", description = "glottalstops", manipulators = { base = initialize, node = initialize, } } ============== Rotation for one of the characters is also needed. Here is an experimental test file: https://www.dropbox.com/scl/fi/wi81e23wg17k8jasqpeon/transliteration-glotta… https://www.dropbox.com/scl/fi/rca5v6uusyj6mogyklfpd/transliteration-glotta… Thank you in advance for your guidance.
