Parallel text support
by Denis Maier 21 Sep '20

21 Sep '20

Hi, I'm trying to typeset a parallel text that should appear in columns. The sources are XML, and there I have to use tables for this. So, I thought the easiest way is to use extreme tables for this: ========================= \starttext \dorecurse{3}{\input knuth} \startxtable[split=yes,frame=off] \startxrow \startxcell Text \stopxcell \startxcell Übersetzung \stopxcell \stopxrow \startxrow \startxcell \input ward \stopxcell \startxcell \input tufte \stopxcell \stopxrow \stopxtable \stoptext ========================= However, as it turns out, split only seems to mean that the table is split between rows, individual rows stay on the same page. Is there a better approach? I've found the page-streams, but that seems to be too much... Best, Denis

Old-Style numerals command (\os) breaks conversion of hyphens to dashes
by Art Chimes 21 Sep '20

21 Sep '20

I have a fairly large document, 50-60 pp, with lots of numerals, including hundreds of dates. I wanted to see how it would look with old-style numbers and I assumed I could bracket the whole text section of the document within braces and apply the \os command. I didn't turn out as I expected, however. It did convert the numbers to old-style digits. But it also unexpectedly changed the em and en dashes back to hyphens, as they were entered in the source .tex document. MWE follows below. I could possibly do a search-and-replace but I am hoping there is a simpler way to do it.. I am using Libertinus Serif (which does support old style numerals) and columns, if that matters. Thank you. \starttext First two examples: Brackets surround text including digits, grouped hyphens are {\emph not} converted to en and em dashes. {\os Ford--Chevy 12345 Chrysler---Plymouth 67890 } \blank[line] Next two examples: Brackets surround just the digits, the grouped hypehns {\emph are} correctly converted to en and em dashes Honda--Toyota {\os 12345} Renault---Volkswagen {\os 67890} \stoptext

columns yet again
by Thomas A. Schmitz 20 Sep '20

20 Sep '20

Hi all, I hope everybody made it back home safely after the meeting. It was great listening in, even if I couldn't be there in person, unfortunately! Today's question is an old one, but I'm confused. What I need: two columns, of unequal width, the left column has line numbering; two column layout starts in the middle of pages. What I tried so far: 1. \defineparagraphs allows to have two paragraphs of unequal width, but the line numbering isn't visible: \setuppapersize[A4,landscape][A4,landscape] \setuplayout[grid=yes] \definelinenumbering [original] [step=2,location=text,align=flushright,distance=0.4cm,style=small,color=magenta] \defineparagraphs [Half] [n=2] \setupparagraphs [Half] [before=,after=,align=verytolerant] \setupparagraphs [Half] [1] [width=0.45\textwidth] \starttext \startlinenumbering [original] [start=4] Poetry One Word Per Line is Poetic \stoplinenumbering \nextHalf Prose translation \stopHalf \stoptext 2. columnsets:\usemodule[old-columnsets]: unequal width, but no line numbering: \usemodule [old-columnsets] \setuppapersize [A4,landscape][A4,landscape] \setuplayout [grid=yes] \definecolumnset [numbered] [n=2] \setupcolumnset [numbered] [distance=0.5cm,frame=on] \setupcolumnset [numbered:1] [width=4cm] \setupcolumnset [numbered:2] [width=10cm] \starttext \startcolumnset [numbered] \startlinenumbering[step=1,location=left] Poetry One Word Per Line is Poetic\par % needed, otherwise last line is not indented correctly \stoplinenumbering \column Two \stopcolumnset \stoptext 3. Same example without the first line: line numbers, but width is ignored; both columns are of width 0.5\textwidth. 4. page columns: always start at new page. 5. \startcolumns: like 3.; equal width. In addition, for reasons that are completely unclear to me, the example from the columnsets manual (p. 32) does not compile: \setuppapersize[A4,landscape][A4,landscape] \setuplayout[grid=yes] \showframe \definecolumnset[example][n=3,page=left] \setupbackgrounds[text][text][background=contrast] \setupcolumnset[frame=on,framecolor=color-4,rulethickness=1mm] \definecolor[fakerulecolor][white] \setupcolumnset[example:1][width=2cm] \setupcolumnset[example:2][width=4cm] \setupcolumnset[example:3][width=3cm] \setupcolumnset[example:4][width=3cm] \setupcolumnset[example:5][width=4cm] \setupcolumnset[example:6][width=6cm] \starttext \startcolumnset[example] \dorecurse{5}{ \dorecurse{3}{\fakewords{10}{15}\par} \column[yes] } \stopcolumnset \stoptext ends in "tex error > tex error on line 23 in file /tmp/test.tex: ! Undefined control sequence So I'm a bit confused: what I should use? What is the current status of the diverse columns environments? Have a nice Sunday! Thomas

\startstructurelevel
by Denis Maier 20 Sep '20

20 Sep '20

Hi, I'm using \startstructurelevel so I can nest sections without having to worry about where I am at the moment. (Actually I'm typesetting JATS XML, and there's only one <sec> tag, and using \startstructurelevel makes the mapping easier.) Now, for the bibliography, I need an unnumbered heading. How can I get that? Browsing through the source I came across this: https://source.contextgarden.net/tex/context/base/mkiv/strc-lev.mkvi?search… So, it seems that \startstructurelevel is just an alias for \startsectionlevel. Right? Unnumbered headings can be produced with \startsubjectlevel So, is there a way to let \startstructurelevel the unnumbered variant, or should I just use \startsubjectlevel instead? By the way, is there a reason for the existence \startstructurelevel next to \startsectionlevel? What's the exact purpose of this? Best, Denis

Add arrow tips to axes in lmt_function
by Jairo A. del Rio 19 Sep '20

19 Sep '20

Hi, list! I want to know how to add arrow tips for axes (x, y) to a function. I did the following based on a luametafun example: \starttext \startMPcode{doublefun} draw lmt_function [ xmin=0, xmax=10, xstep=.05, ymin=-2, ymax=2, code="1.5 * math.cosd(240 * math.sqrt(x))", xlabels="no",ylabels="no", sx=2mm, sy=4mm, linewidth=.025mm, offset=.1mm,] xsized 8cm; \stopMPcode \stoptext But I didn't find anywhere in manuals or the mailing list concerning arrows, nor key-value pairs for lmt_function. Thank you in advance. Best regards, Jairo :)

Allow pagebreaks in footnotes
by denis.maier.lists＠mailbox.org 19 Sep '20

19 Sep '20

Hi Is there a setting that prevents footnotes from spreading over more than one page? I have a document where this seems to be the case, but I don't know why. It just looks like ConTeXt tries to keep the complete footnote on one page, which leads to ugly white space at the end of almost every page. (LaTeX has \interfootnotelinepenalty to customize this, but what about ConTeXt?) Best Denis

Error setting up ConTeXt in MacTeX 2020
by Felix Krause 18 Sep '20

18 Sep '20

Hi all, with MacTeX 2020 on a newly installed Mac, I have the problem that ConTeXt doesn't work anymore: $ context file.tex mtx-context | warning: no format found, forcing remake (commandline driven) […] snip lots of lines resolvers | formats | changing to format path '/var/folders/rj/hfjmjx796q102y4v23vh038c0000gp/T/luatex-cache/context/a86c089b384a3076dc514ba966a1fac9/formats/luatex' resolvers | formats | unable to change to format path '/var/folders/rj/hfjmjx796q102y4v23vh038c0000gp/T/luatex-cache/context/a86c089b384a3076dc514ba966a1fac9/formats/luatex' mtx-context | error, no format found with name: cont-en, aborting system | total runtime: 5.315 seconds The [ConTeXt docs][1] say that I should run `mtxrun --generate`, which seems to run successfully, and `context --make`, which finishes with the same „unable to change format path“ error (I believe this is what context automatically does when compiling my file, hinted by the „no format found. forcing remake“ message). I tried explicitly running `context --make cont-en` which yields the same result. The given path does exist on my hard drive. I don't even know if the „unable to change format path“ message is actually an error, but I have no other indicator of what goes wrong. The only line that explicitly says „error“ is the one I get when trying to process the file. Interestingly, I have another Mac where I upgraded from MacTeX 2019 to MacTeX 2020 and everything works there. I made sure that everything is up-to-date with the TeX Live Utility. How can I fix this problem? Regards, Felix [1]: https://wiki.contextgarden.net/Running_Mark_IV

Problem with fonts in Lua
by MANUEL GONZALEZ SUAREZ 18 Sep '20

18 Sep '20

Hi all: I have this minimal example (thanks to Pablo and Charles): \mainlanguage [es] \definefallbackfamily [mainface] [rm] [New Athena Unicode] [preset = range: greek, force = yes] % \definefallbackfamily [mainface] [rm] [Old Standard] % [preset = range: greek, force = yes] \definefontfamily [mainface] [rm] [TeX Gyre Pagella] \definefontfamily [mainface] [ss] [TeX Gyre Heros, scale = 0.75] \setupbodyfont [mainface] \starttext Spanish text \input tufte Greek Text: Μετὰ δὲ ταῦτα οὐ πολλαῖς ἡμέραις ὕστερον ἦλθεν ἐξ Ἀθηνῶν Θυμοχάρης ἔχων ναῦς ὀλίγας · καὶ εὐθὺς ἐναυμάχησαν αὖθις Λακεδαιμόνιοι καὶ Ἀθηναῖοι, ἐνίκησαν δὲ Λακεδαιμόνιοι ἡγουμένου Ἀγησανδρίδου. \stoptext I compile with TeXLive 2020 and Windows 10. I have the two fonts (New Athena Unicode and Old Standard) installed on my system but with New Athena Unicode it does not compile; on the other hand, with Old Standard it does compile. I do not know what I can do. Thanks for the help. Manuel González.

Struggling with startuseMPgraphic and string argument!
by Geert Verhaag 18 Sep '20

18 Sep '20

Hi, I'm trying to pass a string argument value to an MPgraphic but it doesn't seem to work: Tried the following: \startuseMPgraphic{name}{lbl} pair a ; a := (3cm,3cm) ;label.top("\MPvariable{lbl}",a) ; \stopuseMPgraphic \starttext \useMPgraphic{name}{lbl=1} \stoptext The above works as expected! But the following doesn't: \startuseMPgraphic{name}{lbl} pair a ; a := (3cm,3cm) ;label.top("\MPvariable{lbl}",a) ; \stopuseMPgraphic \starttext \useMPgraphic{name}{lbl=abc} \stoptext It yields: 1 \startuseMPgraphic{name}{lbl} 2 pair a ; a := (3cm,3cm) ;label.top("\MPvariable{lbl}",a) ; 3 \stopuseMPgraphic 4 5 %\startuseMPgraphic{name}fill fullcircle scaled 200pt withcolor .625yellow ;\stopuseMPgraphic 6 7 \starttext 8 Example: 9 >> \useMPgraphic{name}{lbl=abc} 10 \stoptext 11 <to be read again> a \m_meta_current_variable a-a bc <argument> ... \hbox {\scratchdimen \m_meta_current_variable sp}\ifzeropt \wd \b_meta_v... \secondoftwoarguments #1#2b-#2 \9>>1 #1,2-\meta_prepare_instance_variable {#1} \syst_helpers_do_process_comm... \syst_helpers_do_process_comma_list ...rgument #1, ]\relax \global \advance \... ... l.9 \useMPgraphic{name}{lbl=abc} So it seems that only numbers can be passed not character strings! Why is that? Is there a possibility to achieve this functionality? Regards, Gerard
