sqrt does not align properly
by Benny Schurig 05 May '21

05 May '21

Peak of the root ends at baseline, but only in some cases: \starttext $\sqrt{2}$ \qquad $\sqrt{a^2+b^2}$ \qquad $\sqrt{a^2-b^2}$ \stoptext In this example only \sqrt{a^2+b^2} works as expected [ConTeXt ver: 2021.04.29 23:09 LMTX fmt: 2021.5.4] Typesetting in ConTeXt live is correct. Benny

conditionally add \vfill before section if at end of page
by denis.maier＠ub.unibe.ch 04 May '21

04 May '21

Hi, I'm still playing/struggling with vertical glue to have pages of a constant height. The following settings give reasonable results: ============= \setuppapersize[A5][A5] \setupalign[line] \setuptolerance[vertical,stretch] \setupinterlinespace[ stretch=0.001, shrink=0.001, ] \showframe \starttext \section{Section} \input knuth\par \input knuth\par \input knuth\par \input ward \input ward \input ward %\vfill % can a \vfill be added automatically here? \section{Section} \input knuth\par % here we don't have a \vfill as this is on the middle of the page \section{Section} \input knuth\par \stoptext ====================== However, I don't want the stretching if the next page starts with a section heading. Is there any way to add a \vfill on a page immediately before a section heading? \doifatpageborder \doifatpagestart or something similar ? Thanks for you help, Denis

by Taco Hoekwater 03 May '21

03 May '21

TL;DR: See https://meeting.contextgarden.net/ for registration! Hi all, Registration for the next ConTeXt meeting is now open! 15th International ConTeXt Meeting ================================== The thirteenth ConTeXt meeting will take place in Bassenge, Belgium on September 20-25, 2021 You are cordially invited to join the 15th ConTeXt meeting. The meeting will host ConTeXt and Lua(Meta)TeX developers and users and gives you the opportunity to present your results, experiences and ideas on future development. The talks will be followed-up by tutorials on different ConTeXt and Lua(Meta)TeX techniques. Our meeting will take place in person since we assume vaccination levels will be high enough by then that travel restrictions will be lifted (yeah!). Alternatively, it is also possible to register for on-line attendance so you can listen to the talks from your home office. On-line attendance is free, but only open to ConTeXt Group members. Thematic context ================ The theme for this meeting is: expanding orbits You can interpret that any way you want. But, as in previous years, anything at all related to ConTeXt that you would like to share is an acceptable subject for a presentation, tutorial, discussion, Q&A session, demonstration, workshop, recital, sketch, or sermon. The programme committee is Hans Hagen and Taco Hoekwater. Social context ============== Registration opened today. We will be back in ’t Sjetootje in Bassenge-Boirs, the same location as the meetings in 2011, 2014 and 2019. There has been some remodelling (there is now an actual conference room with built-in wifi!) but the basic layout of the chateau has not changed so, as before, (single) rooms are very scarce. Note that the meeting starts on Monday evening and ends on Saturday morning. It is possible to stay on for another day (or even two, if you are OK with getting up early on Monday the 27th). Arriving early is not possible, though. Calendric context ================= • May 3, 2021, beginning of registration • July 1, 2021, deadline for early bird payment • September 20-25, 2021, 13th ConTeXt Meeting See https://meeting.contextgarden.net/ for more details. Hope to see you in September, Taco (your local organizer this year) — Taco Hoekwater E: taco(a)bittext.nl genderfluid (all pronouns)

custom zig zag sidebars
by mf 29 Apr '21

29 Apr '21

Hello, I made an experiment to add alternatives to sidebars (see attachment). I discovered the sidebar is drawn by anch_sidebars_draw in metapost/context/base/mpiv/mp-apos.mpiv. I've redefined it locally to add alternatives. To make fancy, zig zag bars I defined a macro, draw_pattern_bar, that draws a bar repeating a pattern which is a path connecting (0,0) and (1,0). The macro has 3 parameters (actually it has more params, but the remainder are anch_sidebars_draw params): - a pattern, which is a path from (0,0) to (1,0) that should have a vertical size = 1; it's a sort of waveform - a pattern length, by which the pattern is xsized - a pattern width, by which the pattern is ysized Then the pattern is rotated along the bar direction (so -90 degrees) and drawn many times until it covers the bar length. A proposal and a question: - patternlength and patternwidth could become \setupsidebar params; alternative (=2,3,4...) could be used to specify the pattern (a sort of waveform); currently alternative=0 is a solid bar and alternative=1 is a dashed one - in case of long patterns (a patternlength spanning more lines of text) the last replica of the pattern should be clipped not to exceed the last line of the sidebarred text (see the last example): how can that be done?

calculating optimal height of textblock
by denis.maier＠ub.unibe.ch 29 Apr '21

29 Apr '21

Hi, how do you usually calcultate your layouts? For example in this example, the third value for height is not really helpful as there will never be a complete line : ================= \setupbodyfont[10pt] \definepapersize[test][width=140mm,height=208mm] \setuppapersize[test][test] \setuplayout[reset] \setuplayout[backspace=17mm, topspace=19mm, header=0mm, footerdistance=4mm, footer=5mm, width=105mm, %height=174mm, height=178mm, %height=177mm, % does not suffice for a complete line rightmargin=0mm, leftmargin=0mm, ] \startsetups[mypenalties] \setdefaultpenalties \setpenalties\clubpenalties{2}{0} \setpenalties\widowpenalties{2}{0} \setpenalties\displaywidowpenalties{2}{0} \stopsetups \setuplayout[setups=mypenalties] %\showframe \showmakeup %\showsetups \starttext \dorecurse{5}{\input knuth\par} \stoptext ================= How do you do this usually? Any best-practices? Hints? Trial and error seems to work ok, but maybe there is a more efficient method... Best Denis

layers x 2
by jbf 28 Apr '21

28 Apr '21

Hi list, Is it possible to place two layers on the same page? I have several pages where that would be necessary. On the first of those pages, it did actually work, but on the remaining other pages, the second layer, even though located at the bottom of the page, eliminates the first layer. I have simply set them up one after the other. As you can see, the 1st is towards the top left of the page, while the second is bottom right. \definelayer[blessings] % name of the layer [x=0mm, y=0mm, % from upper left corner of paper width=\paperwidth, height=.5\paperheight] % let the layer cover the full paper \setlayer[blessings] % name of the layer [hoffset=.09\textwidth, voffset=1.7cm] % placement (from upper left corner of the layer) {\externalfigure[bless.eps][width=3cm]} % the actual contents of the layer \setupbackgrounds[page][background=blessings] \definelayer[tree] % name of the layer [x=0mm, y=0mm, % from upper left corner of paper width=\paperwidth, height=\paperheight] % let the layer cover the full paper \setlayer[tree] % name of the layer [hoffset=.75\textwidth, voffset=15.1cm] % placement (from upper left corner of the layer) {\externalfigure[Pohutukawa.jpg][width=.5\textwidth]} % the actual contents of the layer \setupbackgrounds[page][background=tree] What am I doing wrong?

Style options and setupinterlinespace
by denis.maier＠ub.unibe.ch 27 Apr '21

27 Apr '21

Hi, the wiki (https://wiki.contextgarden.net/Font_Switching) currently says: > These quick font switches are meant for changing the font style, alternative, or size of a few words: they do not change the bodyfont, so they don't affect interline spacing or math font sizes. So, if you want to change the font size of an entire paragraph, use \switchtobodyfont<https://wiki.contextgarden.net/Command/switchtobodyfont> described below in Complete Font Change<https://wiki.contextgarden.net/Font_Switching#Complete_font_change>. However, it is fine to use them as style directives in setup commands, that is, using them as an option for style=<https://wiki.contextgarden.net/Style_and_Color_Parameters>... in any setup command that accepts style option >From this, I'd infer that a <style=tfx> or <style=\tfx> should change the interline spacing as well. But it does not seem to be the case as the example below shows.

Bug: missing Lua API in binaries

Dear Devs, Sorry if this is not the best place for reporting bugs. I'm trying to use the lpeglabel library written in C and delivered as lpeglabel.so. $ ls testlabel.lua lpeglabel.so $ cat testlabel.lua require("lpeglabel") The ConTeXt binary cannot load the library because it lacks certain Lua API: $ context --forcecld --permitloadlib testlabel.lua ... fatal lua error: registered function call [1542]: ...tx/tex/texmf-context/tex/context/base/mkiv/l-package.lua:348: error loading module 'lpeglabel' from file './lpeglabel.so': ./lpeglabel.so: undefined symbol: lua_gettop ... nor does LuaTeX: $ luatex -luaonly testlabel.lua error loading module 'lpeglabel' from file './lpeglabel.so': ./lpeglabel.so: undefined symbol: lua_getiuservalue It seems that lua_gettop and others are optimized out from the `context` binary, while lua_getiuservalue and others are missing from `luatex`. I'm not sure if it works but I would suggest adding `__attribute__ ((used))` to the `LUA_API` macro if the binaries are compiled with gcc. Best, Sylvain

Used XML input has two types of non-breakable space: - unicode character - html entitity (in fact an ugly output of HTML editor) HTML is preprocessed with ctx preprocessor (great feature!) and substituted for unicode char nbsp or tilde. MWE shows unichar spaces are non-breakable (see end of the first lines), however they are not stretchable (see second line of the paragraphs). Does unicode nbsp have fixed with in ctx? When tilde is the replacement in preprocessor (uncomment first replacement in preprocessor), xmlfush will display tilde (which is, as character, non-breakable and unstretchable, no surprise). Why tilde is displayed? Replacing or adding nbsp (tilde) with finalizers have different results, see next episode after this one is understood. Thank you, Jano MWE (rather use attached file not to loose invisible characters): \startbuffer[doc] <?xml version "1.0"?> <document> <p>Temperature 20 °C 20 °C 20 °C 20 °C average.</p> <p>Altitude 6000&nbsp;m 6000&nbsp;m 6000&nbsp;m 6000&nbsp;m average.</p> </document> \stopbuffer \startluacode function lxml.preprocessor(data) -- data = string.gsub(data, "&nbsp;", "~") -- replacement nbsp invisible in luacode data = string.gsub(data, "&nbsp;", " ") return data end \stopluacode \startxmlsetups xml:name \xmlsetsetup{\xmldocument}{*}{-} \xmlsetsetup{\xmldocument}{document|p}{xml:name:*} \stopxmlsetups \xmlregistersetup{xml:name} \startxmlsetups xml:name:document \xmlflush{#1}\par \stopxmlsetups \startxmlsetups xml:name:p \parfillskip0pt\xmlflush{#1}\par \stopxmlsetups \startTEXpage[offset=5mm,width=60mm] \xmlprocessbuffer{xml:name}{doc}{} \stopTEXpage

ToC filler dots/leaders not aligned in LMTX
by Schister, Roman 23 Apr '21

23 Apr '21

Hello everyone I’m trying to typeset a table of contents with filler dots (list alternative C) in LMTX. Unfortunately, the dots are not vertically aligned and do not end flush on the right-hand side. If I try to use leaders in a paragraph, I get the same behaviour: the leading dots are not aligned. Compiling the same document with MkIV leads to correct alignment of the filler dots in both instances. Here is an MWE: \setuplistalternative[c][width=2em] \starttext \completecontent[alternative=c] \chapter{Short title} Lorem ipsum \hskip.5em\gleaders\hbox to .5\emwidth{\hss.\hss}\hfill\hskip.5em\relax dolor sit amet. \par Lorem \hskip.5em\gleaders\hbox to .5\emwidth{\hss.\hss}\hfill\hskip.5em\relax ipsum dolor sit amet. \chapter{Slighlty longer title} \chapter{Not so long title} \stoptext Are there any changes in LMTX that I need to take into account when typesetting a ToC/leaders? Any help is much appreciated. Thank you! Roman

setupalign[height] vs setupalign[line] in MKIV
by denis.maier＠ub.unibe.ch 23 Apr '21

23 Apr '21

Hi, I've noticed a somewhat unexpected behaviour. MWE below. \setupalign[line] adds an enormous amount of whitespace to fill a last page, but \setupalign[height] doesn't. Is that intended ? Currently this only happens with mkiv. As stated in another mail, these options seem to have no effect at all under LMTX. Best, Denis \setuppapersize[A5][A5] \showframe \setupdelimitedtext[blockquote] [before={\switchtobodyfont[small]}, spacebefore={medium,flexible},] \starttext \setupalign[line] % this here causes the last page to be filled \section{A section heading} \input knuth\par \page \setupalign[height] %this here doesn't \section{A section heading} \input knuth\par \stoptext

Page building and vertical stretching
by denis.maier＠ub.unibe.ch 22 Apr '21

22 Apr '21

Hi, in addition to my previous mails about \setupalign[height], a further question related to page building : I'm trying to understand how ConTeXt builds pages, and how this can be influenced. Regarding the example below, the aim is to have pages that always end at the same place. Now, how will ConTeXt use stretching? Blanks are set to flexible, and the interlinespacing is set to stretch. (But different values for blockquotes.) In which order will ConTeXt proceed? Interlinespacing first, then blanks? Or the other way round? Or both at the same time? And, can this be influenced somehow? Best, Denis \setuppapersize[A5][A5] \showframe \setupblank[big,flexible] \setupinterlinespace[stretch=0.03] \setuptolerance[vertical,stretch] \setupalign[height] \setuphead [section,subject] [ before={\blank[2*big,flexible]}, after={\blank[big,flexible]}, ] \setupdelimitedtext[blockquote] [ before={\tfx\setupinterlinespace[stretch=0.05]}, spacebefore={medium,flexible}, left= ] \starttext \input knuth \section{A section heading} \input knuth\par \blank \input knuth\par \startblockquote \input knuth\par \stopblockquote \input knuth\par \startblockquote \input knuth\par \stopblockquote \input knuth\par \stoptext

Change to wordright behavior?
by Rik Kabel 21 Apr '21

21 Apr '21

Dear all, At some time in the last couple of years the behavior of \wordright seems to have changed, at least in the following situation. With the following example: \starttext \hsize3cm Aaa\wordright{Aaa}\par \sc{Bbb\wordright{Bbb}}\par {\sc Ccc\wordright{Ccc}}\par \sc{Ddd}\wordright{\sc{Ddd}}\par \stoptext Produces: The second and third lines with \wordright (Bbb and Ccc) each generate two lines. They previously produced one line each. Placing each part of the line in its own \sc addresses it here (Ddd), but it does seem that it should not be necessary to do that. Was this an intentional change? -- Rik

next upload
by Hans Hagen 21 Apr '21

21 Apr '21

Hi, The *next* upload will have the following change. For a long time in mkiv and also lmtx, the tex habit of turning -- and --- into endash and emdash has been handled at the font level by a injecting a font feature. This works okay. This tlig feature is currently part of the defaults but that will change. If you want to retain that, you can add this to a cont-loc.mkxl file \definefontfeature [default] [default] [tlig=yes, trep=yes] but it should not be needed (and only introduces overhead). When it's a font feature it kicks in after hyphenation but because we're in the process of enhancing that, this traditional -- and --- replacement now kicks in before hyphenation. It can be disabled by \nohyphencollapsing, which actually happens in for instance verbatim and it can be applied locally if needed. There might be places where you expect this to happen so let me know if I missed these. The (intended) effect is that somefirst- and secondpart\blank firstpart\char"002D secondpart\blank firstpart---secondpart\blank firstpart\char"002D\char"002D secondpart\blank firstpart\char"002D\char"002D\char"002D secondpart\blank firstpart\char"2010 secondpart\blank firstpart\char"2013 secondpart\blank firstpart\char"2014 secondpart \type{firstpart---secondpart} all work as I expect (both words get hyphenated). The trep feature was already stripped to only ' replacment but in these unicode times that artifact has no place. We anyway expect users to use \quote and \quotation as it's a language dependent feature. You can of course enable it any time, but it will no longer be default, just like " already gives an upright double quote, and `` was never enabled in mkiv, from now on ' will give a single upright quote. So, when this is uploaded, keep an eye on it and let me know where things misbehave, you're warned, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

xml processing in latest

Hi all, the latest has some strange problems with xml processing. The example below shows an issue with itemize. In my real file, I also get pages that are filled only two thirds and rugged right instead of justified, but I haven't been able to reproduce this in a MWE.

Analyze hyphenations
by denis.maier＠ub.unibe.ch 18 Apr '21

18 Apr '21

Hi, a couple of weeks ago Hans has implemented a tracker that adds a list of hyphentated words to the log file. I finally managed to play with this. The result is attached to this mail. This will permit analyzing hyphenations based on a ConTeXt log file. You need to enable hyphenation tracking in the ConTeXt file with \enabletrackers[hyphenation.applied]. Then, you can run the script with lua check-hyphens.lua input_file whitelist.ending As we assume .log for the input_file, the input file should be supplied without file ending. For the (optional) whitelist a file ending has to be supplied. Maybe I should wikify this, any suggestion where that would fit? HTH, Denis

lmtx update: two experimental features
by Hans Hagen 18 Apr '21

18 Apr '21

Hi, I uploaded a new version. There are two new features that are experimental. This time we attempt to deal with the more tricky things and artifacts of the otherwise nice tex machinery we need to get rid of. One can rightfully argue that they are not really issues as one can work around them (and so they are never brought to attention) but why not make things better (cleaner) if we can. (1) Languages: hyphenation normally uses a hyphen and the engine has some messy work-around-border-cases in the hyphenator. So, I wondered if we could improve that. First of all, there can now be more than one hyphen character so here is the way to deal with it (the hyphenchar code is like the other 'codes'): \hccode"002D = "002D \hccode"2010 = "2010 \hccode"2013 = "2013 \hccode"2014 = "2014 This makes all these four into (kind of) compound word seperators: \startTEXpage \hsize3mm firstpart\char"002D secondpart\blank firstpart\char"2010 secondpart\blank firstpart\char"2013 secondpart\blank firstpart\char"2014 secondpart \stopTEXpage will work ok. There are provisions for those characters being at the left and right edges. All is under low level (engine) option controls (compatibility and such) but currently I enable all. With a bit of definitions one can for the 002D and 2010 cases deal with pre/post variants .. the question is do we need that for more, if so, then I need to add some more code (doable). This feature relates to Denis collection of German compound words and ligature prevention data. Dutch has the same issue. (Denis: we can ditch the compound word entries now, the ones with -.) Also, this kind of automatism (keep in mind that normally tex won't hyphenate the first word in such a compound) is especially handy in cases where there is no control over the input as with xml (when we do have control you can use || as compound word marker). (I'm wondering if we should deal with the typical somewhat archaic tex -- and --- in a different manner, but I'll come back to that.) (2) Math: what is added is not so much an issue in traditional tex math usage which is for journals but as context is used for educational purposes and thereby has quite some tricks built in. Some of these jump through ugly hoops to get it done. Here I stick to color as example. Just try this (notice the spacing): \startTEXpage[offset=10pt] \showmakeup[mathglue]% \enableexperiments[simplegroups]% $ a = b \color[red]{=} c \startcolor[blue]=\stopcolor d $\par $ \sin \color[green]{(x)} = \sin {(x)} $\par \disableexperiments[simplegroups]% $ a = b \color[red]{=} c \startcolor[blue]=\stopcolor d $\par $ \sin \color[green]{(x)} = \sin {(x)}$\par \stopTEXpage The 'simplegroups' experiment enables a more hybrid grouping model but we (read: Wolfgang, Aditya and I, but input is welcome) need to check for side effects carefully. The 'mathglue' tracker is also new, and it exposes what actually goes on. It has to do with the fact that something grouped with { } creates a math list which enforces different spacing but in the case of color that is a side effect we don't want (of course it relates to how context implements the \color macro and one could work around it, but the problem is of a more general nature.

Sorting items in Lua
by Jairo A. del Rio 18 Apr '21

18 Apr '21

Hi, list. I want to know how to use ConTeXt sorters, as those used in registers, in Lua. Like this: \starttext \startluacode --Spanish local list = {"ñandú", "perrera", "zócalo", "árnica"} --What's "sortingfunction"? context(table.concat(sortingfunction(list)," ")) \stopluacode \stoptext Also, as registers allow to set a language for sorting, I want to know how to do the same through Lua, e.g., sorting the same list according to English and then Spanish rules. I've searched for examples in the archive, but I've only found cases working on the TeX side. Thank you in advance. Jairo

Verbose numbers in swedish

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.

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).

Arabic place names
by jbf 11 Apr '21

11 Apr '21

I have a lengthy text in English which occasionally uses Arabic place names in brackets, e.g. Khàbab ( خبب )is a Syrian town 50 km south of Damascus The text is copy-pasted from a Word file, so I do not have to type the Arabic as such, and would not know how to do that anyway. Since I never usually have to work with Arabic script (though I do have a font installed and recognised by ConTeXt (with the usual mtxrun commands) I am not sure how to achieve this. There might be just half a dozen of these place names involved in a text of some 300 pages worth. The font, BTW is Arslan Wessam A.ttf My humble attempt: I did the following in my preamble: \definefallbackfamily [mainface] [sans] [aarslanwessama] [range=arabic] The rest of the [mainface] setups are obviously western fonts. But the fallbackfamily approach did nothing to help. I also tried: Khàbab {\switchtobodyfont[aarslanwessama](خبب)} is a Syrian town 50 km south of Damascus... but that did nothing either. Am quite out of my depth with this one so any help would be appreciated. Julian

Hyphenation patterns
by Denis Maier 09 Apr '21

09 Apr '21

Hi, where can I find the hyphenation patterns used by ConTeXt? I have two wrongly hyphenated words, and I want to check whether this is due to incorrect patterns. (I tried the source browser... not much luck so far.) The words are: 1. applicable => hyphenated as applic-able 2. obligated => hyphenated as oblig-ated I know I can use \hyphenation to correct that, but I wanted to check the patterns nevertheless. Best, Denis

new upload
by Hans Hagen 09 Apr '21

09 Apr '21

Hi, I uploaded a new version of lmtx. (1) The only additions are in the language arena (discussed here before). For those working on that, the trackers hyphenation.applied hyphenation.applied.console hyphenation.applied.visualize[=ligatures] languages.patterns languages.goodies languages.applied have been updated. Also, exceptions can be stored in the goodies files (and then follow a slightly different route). There's also (at the engine level): \tracinghyphenation which is 1 by default (report bad patterns, as before); a value of 2 reports hyphenation and exceptions states, while 3 also adds detail if it has been applied. (2) A second aspect of the upload concerns windows. Till now we use binaries that are crosscompiled on linux. These perform somewhat better than native msvc compiled binaries ... until last week. The native windows binaries now are some 5+ % faster than the cross compiled ones. However, because it is still somewhat experimental, the installation uses the ming ones. (Running the test suite went down from 1350 sec cross compiled to 1200 seconds native.) If you want to check this out, fetch the binaries from the build server: https://dl.contextgarden.net/build/luametatex/win64/ make sure you replace/link luametatex.exe, mtxrun.exe and context.exe so that all then use the replacement. Mojca also configured the setup for native 32 bit binaries in case you need those. (The clang variants are compiled because want to keep an eye on that but they are definitely slower.) If this experiment works out ok I might also investigate it for other platforms. The gain is mostly in the lua department, less in metapost and tex but still a valid reason to use my laptop for another few years. (It is anyway cheaper and more environment friendly to make luametatex faster than to buy a new machine.)

Ligature suppression word list
by denis.maier＠ub.unibe.ch 08 Apr '21

08 Apr '21

Hi everyone Now that Hans has implemented the new ligature suppression mechanism via language goodies - thanks again Hans! - we now need to come up with wordlists. I've started working on a list of German words with ligatures that should be suppressed. The list is derived from the word list that comes with the lualatex selnolig package: https://github.com/micoloretan/selnolig/blob/master/selnolig-german-wordlis… You can find the current list here : https://github.com/denismaier/context-nolig-wordlist The list is currently organized as follows : 1. L.25-l.35: This specifies words where automatic pattern matching is more difficult than usually because the words contain multiple ligatures, some of which must be suppressed while others must be preserved. In the case of « Auflagefläche » it's even the same combination of letters. So here, we use the bar | to manually indicate points where no ligature must occur. 2. L. 36ff.: The vast amount of words is currently in that list that specifies words where a ff, fl, fi, ffi, or ffl ligature has to be broken up after the first f. 3. L.1804ff contain words where ffi, ffl, or fff ligatures have to be prevented after the second f, so the first two fs form a ligature. 4. The remaining blocks starting at L.1900, l. 2073, l. 2157, l. 2225, and l. 2277 suppress ligatures for « ft » and « fft », « fb » and « ffb », « fh » and « ffh», «fj» and «ffj», and «fk» and «ffk» Obviously, that list is far from being complete, and the question is if it ever can be. Please have a look and feel free to propose more words to be included - either via mail or directly on github. More generally, there's the question how such a list should be enhanced? I was thinking about two options: 1. The new language options features include a tracker that allows for tracking for which words in a given document ligature prevention happened, and which words haven't been touched by the mechanism. It should be possible to analyze the log file and to create lists of words with ligatures. Should be a rather simple step to derive new words for the ligature-suppression wordlist. 2. A bigger solution might be to use selnoligs patterns in a script that can be run over a large corpus, such as the DWDS (Digitales Wörterbuch der deutschen Sprache). That should produce us a more complete list of words where ligatures must be suppressed. What do you think? Best, Denis

Suppressing headers and footers on blank pages before pagebreak at the end of a chapter.
by rha17＠t-online.de 07 Apr '21

07 Apr '21

Hi list, I typeset my first project with ConTeXt, a small booklet with some chapters, frontmatter, no headers, but pagenumbers in the middle of the footers. I use two environment files. The text is split into component TeX-files. All is structured by a project and a product file. Now I have run in some problems, I couldn’t solve with the garden and the archives of this and stackexchange’s list. But I’m sure that it is almost too simple for you experts. Let’s start with one. As intended, a new chapter starts on a right/odd page. If the chapter before ends on a right page, too, there should be a blank left/even page. But in my case there is the pagenumber in the footer – which looks more horrible than an orphan line. A. Which setting in which setup or definition gives a command like: suppress/skip/hide the header, footer and margin of last page of a chapter, if the text area is empty. B. More elaborate, a set of commands could – distinguish between headers, footers, an margins and – extend the commands on those pages at the end of the chapters – that do not show any text within the last line of the text area, i. e. the very last page of a chapter (even, but whith some text) – or the second last page (odd, with some text, before a complete blank even page). A book design according to (A) is standard. I’m sure there is a solution in ConTeXt. (B) can be found often, at least in books from pre-computer times. Ralf

"Scheduled" downtime of the contextgarden server
by Mojca Miklavec 05 Apr '21

05 Apr '21

Dear ConTeXters, There will be a "scheduled" downtime of the contextgarden.net server for maintenance reasons (the part that's hosted in Slovenia; that excludes wiki & modules, but includes the old distribution, buildbot CI, CTAN, TL pretest & w32tex mirror, ...) in one of the following days. It's not yet clear when exactly the downtime will happen (and all the lockdowns etc. make that even harder to predict) and I'm also not entirely sure how long it will take, this is just to give you a notice upfront. Mojca (PS: I hope that TL 21 won't need any further builds, else we can postpone this.)

Floating objects next to text mess up paragraph spacing
by Daniel Barker 01 Apr '21

01 Apr '21

Hi all, I have noticed that placing a floating object next to text with location "left", "right", etc. seems to move the current paragraph slightly up, resulting in too little space between the current and previous paragraph. This can be seen quite clearly in the output of the following example: \setupbodyfont[dejavu, serif, 12pt] \starttext \samplefile{lorem} \startplacefigure[location={right, none}] \framed[width=3cm, height=2cm]{graphic} \stopplacefigure \samplefile{lorem} \samplefile{lorem} \stoptext I am using the current (2021.03.31 18:04) version of ConTeXt LMTX. On ConTeXt live, which seems to be running an older version, this does not occur, i.e. the spacing is even, as I would expect it to be. I assume this is a bug, or am I doing something wrong? Thank you, Daniel

README for pending new subscribers March 2021
by Taco Hoekwater 01 Apr '21

01 Apr '21

Hi all, Regretfully, we have had problems with a hacker messing with the html subscription page of this mailing list. In mitigation, we have disabled web - based subscription requests completely. From now on, subscription to this mailing list can only be requested by sending an email message to ntg-context-request(a)ntg.nl with “subscribe" as the Subject. Unfortunately, it was impossible for us to differentiate between "hacked" and “legit” subscription requests made during the month of March 2021 so to prevent our mail server from being blacklisted as email sender we have had to discard all pending subscription requests. This means that anyone that has tried to subscribe to ntg-context during the past month (that has not received a confirmation message from mailman welcoming them to the mailing list) will have to re-start the subscription process. Apologetically, Taco — Taco Hoekwater E: taco(a)bittext.nl genderfluid (all pronouns)

new upload
by Hans Hagen 31 Mar '21

31 Mar '21

Hi, I uploaded a new version. However, because of some new feature there can be (unwanted) side effects wrt hyphenation (should not be but who knows). As a follow up on Denis mails about ligature prevention, we now have a mechanism called language 'goodies' analogue to 'font goodies'. For practical reasons this permits (high performance) plugs into the mechanism that also deals with hyphenation. Basically we can have some feedback loop but more about that later (Denis, Wolfgang and I need to play with all this and settle on the interface). Although all can be done in pure lua (and i might add that at some point) this particular mechanism plugs into the hyphenator so that we get no real performance hit (I can proabbly improve it if really needed but let's first see if users complain.) Here is an exmaple (to be default or not?) \setuplanguage [de] [goodies={lang-de.llg}] that has to come before a lkanguage gets activated (for now). In addition to exceptions one can do \startlanguageoptions[de] Zapf|innovation \stoplanguageoptions to prevent a ligature between f and i and \startlanguageoptions[de] Zapf=innovation \stoplanguageoptions to make it into a compound word (use both to prevent ligatures too). There's more to come once we get the full picture. I leave it to Denis to organize the collection of words and definitions that go into a goodie file. Hans ps. Sometimes I wonder if for every new feature added we should drop an old maybe useless one, like some of the obsolete pdf stuff or features that seem to be persistently broken or weird or unpredictable in viewers. After all evolution also takes care of removal. ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

(or another macro with a similar purpose) with different macros at the TeX end once Lua has delivered results. How should I do it in ConTeXt? Thanks in advance. Cordially, Jairo

issue field in bibliography
by Damien Thiriet 29 Mar '21

29 Mar '21

Hi, I have questions related with a journal named "Documentation photographque". Each issue is devoted to another theme. How should I declare this theme in bibliography fields when quoting articles? It is quite important to get it, because the main article is always named « Le point sur… » (I don't know exactly how to translate it in English. Something like "an overview of…") so quoting it makes only sense if the issue is named, at best after the title or the number. I thought issue may do it. Am I right? Or would be comment a better place? Best regards, Damien Thiriet

XML/MathML namespace handling bug
by Hugo Landau 26 Mar '21

26 Mar '21

Thanks for ConTeXt, it is an amazing system. The following test case demonstrates the bug. \usemodule[mathml] \starttext \xmlprocessdata{}{ <?xml version="1.0" encoding="utf-8"?> <foo xmlns="http://www.example.com/ns/foo" xmlns:m="http://www.w3.org/1998/Math/MathML"> <m:math version="2.0"> <m:apply><m:union/><m:ci>a</m:ci><m:ci>b</m:ci></m:apply> </m:math> <m:math version="2.0"> <m:apply><m:selector/><m:ci>a</m:ci><m:ci>b</m:ci></m:apply> </m:math> </foo> }{} \stoptext No output is produced. This has been verified with live.contextgarden.net. In order for output to be produced, <m:union/> must be changed to <union> and <m:selector/> must be changed to <selector/>, but these are in the wrong namespace in this context. In other words, this bug applies to the keyword element in an apply element. Hugo Landau

metafun / patterns

Hi, As I'm still in metafun (and svg) mode I decided to support patterns (that are already supported at the tex end) also in metafun. As there has never been demands I suppose it's not that interesting but it sort of fits in. There are some tricky aspectx involved so the interface might evolve a bit (some more control options) but here are some examples anyway: \starttext \startMPpage[offset=1cm] draw (fullcircle scaled 5cm shifted (0cm,0cm)) withpattern image (fill fullcircle scaled 1cm withcolor "darkblue" ;) withpatternscale (1/10,1/10) ; draw (fullcircle scaled 5cm shifted (5cm,0cm)) withpattern image (fill fullcircle scaled 5mm withcolor "darkred" ;) withpatternscale (1/20,1/20) ; draw (fullcircle scaled 5cm shifted (10cm,0cm)) withpattern image (fill fullcircle scaled 5mm withcolor "darkgreen" ;) withpatternscale (1/40,1/40) ; draw (fullcircle scaled 5cm shifted (0cm,5cm)) withpattern image (fill fullcircle scaled 1cm withcolor "darkcyan" ;) withpatternscale (1/10,1/20) ; draw (fullcircle scaled 5cm shifted (5cm,5cm)) withpattern image (fill fullcircle scaled 5mm withcolor "darkmagenta" ;) withpatternscale (1/20,1/40) ; draw (fullcircle scaled 5cm shifted (10cm,5cm)) withpattern image (fill fullcircle scaled 5mm withcolor "darkyellow" ;) withpatternscale (1/40,1/80) ; \stopMPpage \startMPpage[offset=1cm] fill fullcircle scaled 11cm withcolor "darkyellow" ; draw fullcircle scaled 10cm withpattern image (fill fullcircle scaled 1cm withcolor "darkblue" ;) ; draw fulldiamond scaled 8cm withpattern image (fill fulldiamond scaled 4mm withcolor "darkgreen" ;) rotated 15 ; draw fulltriangle scaled 9cm withpattern image (fill fulltriangle scaled 3mm withcolor "white" ;) rotated 45 ; draw fullcircle scaled 10cm withpattern image (draw textext("!") withcolor "middlegray" ;) rotated 45 ; draw fullcircle scaled 10cm withpen pencircle scaled 1mm withcolor "darkgray" ; \stopMPpage \startMPpage[instance=doublefun] draw closedcurve(unitsquare xyscaled (200,200) shifted (0,-200)) withpattern image (fill closedcurve((fullcircle scaled 40 shifted (25,-25))) withcolor "darkgray" withopacity .5) withpatternscale (1,1) ; draw closedcurve(unitsquare xyscaled (200,200) shifted (0,-200)) withpattern image (fill closedcurve((fullcircle scaled 40 shifted (25,-25))) withcolor "darkred" withopacity .5) withpatternscale (1/2,1/2) ; draw closedcurve(unitsquare xyscaled (200,200) shifted (0,-200)) withpattern image (fill closedcurve((fullcircle scaled 40 shifted (25,-25))) withcolor "darkgreen" withopacity .5) withpatternscale (1/3,1/3) ; draw closedcurve(unitsquare xyscaled (200,200) shifted (0,-200)) withpattern image (fill closedcurve((fullcircle scaled 40 shifted (25,-25))) withcolor "darkblue" withopacity .5) withpatternscale (1/4,1/4) ; \stopMPpage % \startTEXpage \page \startMPcode{doublefun} draw closedcurve(unitsquare xyscaled (200,200) shifted (0,-400)) withpattern image (fill closedcurve((fullcircle scaled 40 shifted (25,-25)))) withpatternscale (1/8,1/8) ; \stopMPcode \blank \startMPcode{doublefun} draw closedcurve(unitsquare xyscaled (200,200) shifted (0,-400)) withpattern image (fill closedcurve((fullcircle scaled 40 shifted (25,-25)))) withpatternfloat true withpatternscale (1/8,1/8) ; \stopMPcode \page % \stopTEXpage % \startMPpage[instance=doublefun] % draw closedcurve(unitsquare xyscaled (200,200) shifted (0,-200)) % withpattern image ( fill closedcurve(unitsquare xyscaled (50,50) shifted (0,-50)) withcolor svgcolor(0.529,0.808,0.922) ; fill closedcurve(unitsquare xyscaled (25,25) shifted (0,-25)) withshademethod "linear" % withshadecenteronefraction (0,1) % withshadecentertwofraction (0,0) % withshadestep ( withshadefraction 0.05 withshadecolors (svgcolor(1,0,0),svgcolor(1,0,0)) ) % withshadestep ( withshadefraction 0.95 withshadecolors (svgcolor(1,0,0),svgcolor(1,0.5,0)) ) ; fill closedcurve((fullcircle scaled 40 shifted (25,-25))) withshademethod "linear" % withshadestep ( withshadefraction 0.05 withshadecolors (svggray(1),svggray(1)) ) % withshadestep ( withshadefraction 0.95 withshadecolors (svggray(1),svgcolor(0,0,1)) ) withopacity 0.5 ; ) % withpatternscale(1/4,1/4) % ; % \stopMPpage % \startTEXpage % \externalfigure[test.svg][conversion=mp,xobject=no] % \stopTEXpage \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Hans, the following sample (from https://pragma-ade.com/general/manuals/workflows-mkiv.pdf#search=resort) doesn’t get right output with LMTX (current latest from 2021.03.25 14:04): \showinjector \setinjector[register][3][\column] \setinjector[list][2][{\blank[3*big]}] \starttext \placelist[section][criterium=text] \blank[3*big] \placeregister[index][criterium=text] \page \startsection[title=Alpha] first \index{first} \startsection[title=Beta] second \index{second} \startsection[title=Gamma] third \index{third} \startsection[title=Delta] fourth \index{fourth} \stoptext MkIV compiles this source fine, so I think this might be a bug.

PDF custom properties
by Alan Bowen 25 Mar '21

25 Mar '21

I should like to set the PDf properties so that the Document Info panel has Editor ... Title ... Subtitle ... Subject ... Keyword .... The problem is that currently \setupinteraction[subtitle=text,] goes to Subject and that there are no keys to get output labelled Subject or Editor. I have experimented with \pdfbackendsetinfo{ key }{ Text } but, so far, unsuccessfully. If this is possible,any suggestions about how to do it will be most welcome. Alan

Grid typesetting, blockquotes in smaller font across pagebreaks
by denis.maier＠ub.unibe.ch 25 Mar '21

25 Mar '21

Hi, I'm playing around with grid typesetting. Consider the following example: -------------------------------------- \setuppapersize[A5][A5] \setupbodyfont[10pt] \setuplayout[grid=yes] \showgrid \setupdelimitedtext[blockquote] [ style=\tfx, %style=\tfx\setupinterlinespace, % this breaks grid snapping spacebefore=halfline, indentnext=no, leftmargin=no, rightmargin=no, ] \starttext \dorecurse{5}{ \dorecurse{5}{Some text on a grid. } \startblockquote \dorecurse{10}{A quotation in a smaller font. } \stopblockquote \dorecurse{5}{This should be on the grid again. }} \stoptext -------------------------------------- With style=\tfx it kind of works as long as the quotations don't run over page boundaries. With style=\tfx\setupinterlinespace paragraphs after quotations don't snap back to the grid. Spacebefore=line is somewhat better, but also only if I use \tfx without \setupinterlinespace. Any hints? (But maybe I'm approaching the problem from the wrong direction anyway... I need the have pages end consistently at the same baseline, and I thought grid typesetting might be an option here. But maybe that was a wrong assumption in the first place... Or there are better solutions.) Best, Denis

Summing up ligature prevention tests
by denis.maier＠ub.unibe.ch 25 Mar '21

25 Mar '21

Hi, Trying to sum up what we currently have regarding ligature prevention, it looks like we have three mechanisms available: 1. \replaceword[set][input][output] Ex.: \replaceword[ligs][Auflage][Au{fl}age] Replaces a word input with the corresponding output. Doesn't work at the moment with LMTX. Can be used for words with multiple wrong ligatures (Auflaufform). Does not take derived forms into account (e.g., replacements for Auflage and Auflagen must both be defined). 2. \blockligatures Works as a font feature to block certain ligatures Works also for derived forms of a given word (e.g., \blockligatures[Au:fl:age] will also block the fl-ligature in "Auflagen"). Currently, can't be used when multiple ligatures should be suppressed. \blockligatures[Au:fl:au:ff:orm] blocks the fl-ligature, but the ff-ligature still shows up. This here seems to works though: \blockligatures [ Au:fl:auf, au:ff:orm, ] Don't know if there are unwanted side-effects to that approach. 3. \startexceptions Works via hyphenation exceptions. To define exceptions for "Auflage" and "Auflaufform" use: \startexceptions[de] au{f-}{l}{fl}(f\zwnj l)age Au{f-}{l}{fl}(f\zwnj l)au{f-}{f}{ff}(f\zwnj f)orm \stopexceptions This does not work automatically for derived forms; you'll have to define plural and other forms as well. As this works with hyphenation exceptions you'll have to add legal hyphenation points as well, so for "Auflage", you will actually need: \startexceptions[de] au{f-}{l}{fl}(f\zwnj l)a-ge \stopexceptions IMO, the \blockligatures is the cleanest, both conceptually and syntax wise. Being able to implicitely disable derived forms is a big plus, but of course there may be drawbacks I don't see now. The only downsides I see currently is that you need workarounds to block multiple ligatures in a single words, of which there might not be too many. And, it's kind of an "all or nothing" approach as you cannot define sets of blocked ligatures. (But that may not be a relevant use case anyway.) Anything, I've missed? Other aspects to think about here? How about performance issues? (The blockligatures-mechanism resulted in this: with a word list of about 2200 words it took a bit more than five seconds to process 23 A5 pages than 2.5 seconds without the blocked ligatures. I'll test with the other methods later or tomorrow.) Denis

Writing to .tuc directly from Lua
by Jairo A. del Rio 25 Mar '21

25 Mar '21

Hi, list. I read about this: https://www.mail-archive.com/ntg-context@ntg.nl/msg60217.html But I want to know how to pass data to the .tuc file directly from Lua. I think about some complex strings are calculations which are done in each pass and slow down the whole compilation process. Something like: local function factorial(n) if in_tuc then -- whatever in_tuc means return factorials[n] else ... factorials[n] = ... return ... end end Is that feasible? Should I use the CLD versions of the TeX macros instead? Best regards, Jairo

No, no actually. I only put a toy example. What I need to solve is related with storing data in the .tuc file when processes take a long time. Memoization doesn't work as data is lost with each new run.

Formulanumbers in margin
by Adam Reviczky 24 Mar '21

24 Mar '21

Hi, One more question on formulas. How can I get the formula number to be put into the left/right margin instead of left/right inside the text? I have tried the following: \starttext \showframe % figure caption into the margin \setupcaption[figure][location={rightmargin}] \startplacefigure[title=Cow] \externalfigure[cow] \stopplacefigure % this makes the formulanumber disappear % \setupformulas[location={rightmargin}] \startplaceformula[reference=eq1,location={rightmargin}] \startformula c^2 = a^2 + b^2 \stopformula \stopplaceformula \stoptext But the setupformulas will make the number disappear entirely, and the placeformula location doesn't seem to take the margin option. Thanks, Adam

Questions regarding \startexceptions and ligature prevention
by denis.maier＠ub.unibe.ch 22 Mar '21

22 Mar '21

Hi, there's this rather new mechanism for preventing ligatures: \startexceptions[de] au{f-}{f}{ff}(f\zwnj f)asse au{f-}{f}{ff}(f\zwnj f)asste \stopexceptions Two questions: 1. Can you have multiple \startexceptions[de] environments ? Will they accumulate ? (I'm thinking about preparing a general list of exceptions, but of course you will also want individual exceptions...) 2. What is the exact meaning of these four arguments ? {1}{2}{3} is clear, but what about the parentheses ? Best, Denis

Hi, Is there a way to have formula numbers showing all prefix segments? When I use prefixsegments, I get the desired numbering in the placelist but not in the formula number itself. For example: \starttext \setupcaption[figure][way=bytext,prefixsegments=1:*] \setupformulas[way=bytext,prefixsegments=1:*] \startsection[title=Section] \startsubsection[title=SubSection] \startplacefigure[list=cow] \externalfigure[cow] \stopplacefigure \startplaceformula[reference=eq1] \startformula c^2 = a^2 + b^2 \stopformula \stopplaceformula \stopsubsection \stopsection \placelistoffigures[criterium=all] \placelist[formula][criterium=all] \stoptext The figure has number 1.1.1 and is in the list as 1.1.1, the formula has number 1.1 but is listed as 1.1.1. I would like to have the formula numbered 1.1.1 as well (as referenced in the placelist), so with section and subsection numbering. Adam

How can I pass 'em down so I end up with numbers to do calculations with? \setuplayout[header=15mm] \def\myHeader[#1]#2{ \ignorespaces \getdummyparameters[ref=,next=,#1] \pagebreak[yes] \pagereference[\dummyparameter{ref}] \doassign[header][first=\dummyparameter{ref}] \doassign[header][next=\dummyparameter{next}] {\tfc\bf{#2}}\par \vskip3mm } \def\fillWithText[#1]{ \dorecurse{#1}{ \input tufte \input knuth } } \setupheadertexts[\setups{page:header}]% \startsetups page:header \setupMPvariables[hdrPgs] [curr=\pagenumber, first={\ref[page][\headerfirst]}, next={\ref[page][\headernext]}] \framed[ frame=off, background={hdrPgs} ]{}% all to be done in MP \stopsetups \defineoverlay[hdrPgs][\useMPgraphic{hdrPgs}] \startuseMPgraphic{hdrPgs} StartPage; % calc and draw 'Page x of y'.... numeric numCurr; numCurr := \MPvar{curr}; string strFirst; strFirst := "\MPvar{first}"; string strNext; strNext := "\MPvar{next}"; message("======================="); message("MP_hdrPageNrs: curr="& tostring numCurr & ", sFirst="& strFirst & ", sNext="& strNext); % fails: numeric numFirst; numFirst := \MPvar{first}; StopPage; \stopuseMPgraphic \starttext \myHeader[ref=a,next=b]{AAAA aaaa AaAaAaAa} \fillWithText[10] \myHeader[ref=b,next=c]{BBBB bbbb BbBbBbBbBb} \fillWithText[3] \myHeader[ref=c,next=d]{CCCC ccccc CcCcCcCc} \fillWithText[8] \myHeader[ref=c,next=last]{DDDD ddddd DdDdDdDdDd} \fillWithText[8] \pagebreak[yes] \pagereference[last] This is the last page, goodby \stoptext metapost > message : MP_hdrPageNrs: curr=1, sFirst=\ref [page][a], sNext=\ref [page][b] metafun > log > metafun > log > error: Improper subscript has been replaced by zero metapost > log > <*> ... numeric numFirst; numFirst := \ref [page] metafun > log > metafun > log > A bracketed subscript must have a known numeric value; So MP gets the macro and tries array access... I tried \expanded, \numeric, and resolving the page numbers via \ref[page][id] at the various code levels - unsuccessfully so far - and out of wit now. TIA, Werner

Ligatures missing with Times New Roman
by denis.maier＠ub.unibe.ch 18 Mar '21

Hi I'm have to use Times New Roman for a text, and I'm finding that ligatures don't seem to work properly. \starttext \definedfont[name:timesnewromanpsmt*default at 12 pt] ff fl \definedfont[name:linlibertineo*default at 12 pt] ff fl \switchtobodyfont[pagella] ff fl \stoptext The ff and fl ligatures work out of the box with Linux Libertine O, and with TeX Gyre Pagella, but not with Times New Roman. I can use the ligatures in MS Word so the font has them, but I don't see why they shouldn't work with ConTeXt (LMTX). Best Denis

Math: Nested Cases?
by Weber, Matthias 18 Mar '21

18 Mar '21

Hello, Is it possible to nest cases in math, like so: \starttext \startformula x= \startcases[align={right,left},distance=3pt] \NC a \NC = \startcases[align={right,left},distance=3pt] \NC 1 \NC \text{case a1} \NR \NC 2 \NC \text{case a2} \NR \stopcases \NR \NC b \NC = \startcases[align={right,left},distance=3pt] \NC 3 \NC \text{case b3}\NR \NC 4 \NC \text{case b4}\NR \stopcases \NR \stopcases \stopformula \stoptext I get an error about a missing $ when I try a nested start/stop-cases. Thanks, Matthias

Add items to list with arbitrary page number
by denis.maier＠ub.unibe.ch 18 Mar '21

Hi, I need to add an item to a list with an arbitrary page number. (The reason is that I have a multivolume book, and I want to add information about the other books to the TOC) I know about this: \writetolist[section]{}{It's a test} But how can you add an arbitrary page number ? Best, Denis

placenamedformula in placelist (MKII vs MKIV/LMTX)
by Adam Reviczky 17 Mar '21

17 Mar '21

Hi, I want to use placenamedformula to list a formula in the placelist with both the formula name and the formula number (alongside the pagenumber). The example in the wiki (https://wiki.contextgarden.net/Math/Display) and the test suite (cont-tst/doc/context/tests/mkiv/math/formulas-003.tex) shows what I would like to have. Using MKII I get the desired output (1 formulaname ... and 3b formulaname ...) but with MKIV and LMTX I only get the reference from the placeformula (as 1 and correctly not listed in the placelist) and none of the placenamedformula numbers. The placeformula number is then carried onto the second placenamedformula as 1 (resulting in formulaname ... and 1 formulaname ...). I have attached the test suite file output with both MKII and MKIV. Is there a way to get the MKII output with MKIV/LMTX somehow? Adam
