Setting table of contents depth by number rather than by list
by Jason Ross 24 Dec '21

24 Dec '21

Dear list, Is it possible to set the maximum table of contents depth to a number rather than providing an explicit list of section names? Background: I am developing an exporter for Org mode. In Org, users can specify the number of levels they want in the table of contents with a number. I currently do this by having the sectioning commands be known to the exporter so I can generate a command like \setupcombinedlist [content] [list={section,subsection}] for n=2. I'm considering using \start/stopsectionlevel for sectioning commands instead. That way, users could add \definesectionlevels to the document preamble to use whatever sectioning scheme they wanted. However, this would mean that the exporter wouldn't know what sectioning commands to use the TOC setup. Thanks, Jason

Why are back-to-back \autocite commands not working in ConTeXt-SBL?
by Joel 24 Dec '21

24 Dec '21

I am using the ConTeXt-SBL module to handle the citations in my article. Using the plain \cite[na2006] command has worked fine. But there are some situations where I want the footnote to include page number details. I tried using \cite[extra=2][na2006], but that doesn't seem compatible with ConTeXt-SBL. I checked the documentation, and if I understand correctly, I should use the autocite command to add page numbers to my citation? Like this: \autocite[{\loc[2]}][]{na2006} This solution works in 95% of cases, but when I need to cite another book immediately after that, it throws up errors: This won't compile: \autocite[{\loc[2]}][]{na2006} \autocite[{\loc[2]}][]{clark1989} This won't compile: \autocite[{\loc[2]}][]{na2006}%% \autocite[{\loc[2]}][]{clark1989} This also won't compile: \autocite[{\loc[2]}][]{na2006}\autocite[{\loc[2]}][]{clark1989} After much trial and error, I found this will compile: \autocite[{\loc[2]}][]{na2006} \autocite[{\loc[2]}][]{clark1989} The problem with this last example, is if my citations appear within the paragraph, then I end up with a paragraph break in the wrong place! Here is my minimum working example, which won't compile unless I add a blank line between the two citations. \usemodule[publ-imp-sbl] \startbuffer [bib] @Article{na2006, title={Volcanoes \word{of} New Mexico}, year={2006}, journal={New Mexico Earth Matters}, publisher={New Mexico Bureau \word{of} Geology \word{and} Mineral Resources}, volume={6}, number={1}, location={Socorro, New Mexico} } @Book{clark1989, author = {Clark, William}, title = {Railroads \word{and} railroad towns \word{in} New Mexico}, publisher = {New Mexico Magazine}, year = {1989}, address = {Albuquerque, New Mexico}, isbn = {9780937206126} } \stopbuffer \usebtxdataset[bib.buffer] \setupbtx[dataset=default] \usebtxdefinitions[sbl] \setupbtx[sbl] \starttext \autocite[{\loc[2]}][]{na2006} \autocite[{\loc[3]}][]{clark1989} \startchapter[title=Bibliography] \placelistofpublications \stopchapter \stoptext Is the autocite command the wrong tool for what I need? How can I place citations right next to each other, but also include page number information with ConTeXt-SBL? --Joel

Bug in mp-xbox.mpxl (circleit)
by Jacob Kauffmann 24 Dec '21

24 Dec '21

Hi list, I realized that circleit throws an error. It works fine if I replace boxes_generic_declare by boxes_declare in line 244 in mp-xbox.mpxl rboxit is probably affected as well, but I did not test that. MWE: \startMPinclusions input boxes; \stopMPinclusions \startMPpage circleit.a(textext("$X$")); drawboxed(a); \startMPpage The error (truncated) message: metapost > initializing instance 'metafun:1' using format 'metafun' and method 'default' metapost > loading 'metafun' as 'metafun.mpxl' using method 'default' metapost > initializing number mode 'scaled' metapost > trace > This is MPLIB for LuaMetaTeX, version 3.11, running in scaled mode. metapost > trace > metapost > trace > loading metafun for lmtx, including the plain 1.004 base definitions metapost > trace > metafun > log > metafun > log > error: Isolated expression metafun > log > metapost > trace > <error> boxes_generic_declare metapost > trace > <to be read again> ( metapost > trace > <macro> circleit -> (TEXT3)-> begingroup.boxes_begin("boxes_the_circle","boxes_size_circle",(SUFFIX2),(TEXT3));boxes_generic_declare(pair)_n.n,_n.s,_n.e,_n.w;(SUFFIX2)e-(SUFFIX2)c=(SUFFIX2)c-(SUFFIX2)w=((SUFFIX2)dx,0)+0.5*(lrcorner.boxes_pic(SUFFIX2)-llcorner.boxes_pic(SUFFIX2));(SUFFIX2)n-(SUFFIX2)c=(SUFFIX2)c-(SUFFIX2)s=(0,(SUFFIX2)dy)+0.5*(ulcorner.boxes_pic(SUFFIX2)-llcorner.boxes_pic(SUFFIX2));boxes_end(boxes_clear_circle,(SUFFIX2));endgroup metafun > log > metafun > log > I couldn't find an '=' or ':=' after the expression that is shown above this error message, so I guess I'll just ignore it and carry on. metafun > log > metapost > trace > <direct> circleit.a(textext("$X$")); drawboxed(a); ; metapost > trace > Cheers, Jacob

No pagebreak before chapter
by juh 23 Dec '21

23 Dec '21

Dear all, if I don't want pagebreaks before a chapter, I can do this: \setuphead [chapter,title] [style=\tfb, align=center, number=no, after=, page=no, sectionsegments=chapter, header=empty] In my project this does not work. All chapters start on a new page. What can I do to debug my code? I search for "page=" or "pagebreak" but found no configuration that can cause chapters to insert a pagebreak before. Merry Chrismas to all of you! juh

Re: [NTG-context] Problem with \head inside \itemize
by Benjamin Buchmuller 23 Dec '21

23 Dec '21

Not sure if this is the behavior to expect, but I would like to get formatted inline headers in itemize like: – Unformatted item. – *Head One.* Something bla bla. – *Head Two.* Other bla bla. From: \setupitemize[each][2, headintext] % \setupitemize[each][headstyle={\groupedcommand{\bf}{.\space\tf}}] \setupitemize[each][headcolor=red, headstyle=bold] \startitemize \item Unformatted item. \head Head One \par Something bla bla. \starthead Head Two \stophead Other bla bla. % Even worse: No inline any more. \stopitemize However, headstyle= and headcolor= seem to spill all over … Is it a feature or a bug? Thanks Benjamin

Displaying names in Chicago-Turabian "note" style
by Joel 21 Dec '21

21 Dec '21

I could not find any existing solution for using Chicago-Turabian "note" style in ConTeXt, so I have started my own attempt. Chicago-Turabian uses footnotes to display the author's details on the same page, but also uses a bibliography to display an alphabetical list of the sources again at the end. The footnotes display somewhat differently each time a source is shown. The first time a source is cited, the footnote contains a long, detailed reference. Subsequent reappearances of the same citation are abbreviated somewhat. And "ibid" is used when the source is cited twice in a row. The bibliography entry contains really detailed information, similar to what was shown in the first footnote, with minor differences. This code uses three macros: \turabian, used only the first time a source is reference, \shortturabian, used for subsequent references of the same source, and `\ibid, for when a source is referenced twice in a row. Each of these macros simply creates a footnote, showing the author's details, and also uses \nocite to make sure an entry is added to \placelistofpublications. Page details are optionally added in #2, and this information only appears in the footnotes. I am having trouble getting the code to display the author's names correctly. Every attempt ends with strange results, like "FirstLast" with no space or just "Initial Last". Chicago-Turabian displays the names differently, depending on the placement: (1) First, the \turabian macro should show in ordinary First + Last order in the footnote, example: "Anna Burns, Robert Smith, and Judith Green", but if the number of authors exceeds 3, it display "Anna Burns et al." (2) Second, the \shorturabian macro should show just the Last names in the footnote: "Burns, Smith, and Green", also using "Burns et al." if there are more than 3 names. (3) The \ibid macro doesn't show any names. (4) Finally, the actual bibliographic entry in \placelistofpublications uses a strange format, with the first author listed as Last + First order, all subsequent authors in First + Last order, such as "Burns, Anna, Robert Smith, and Judith Green.", meanwhile "et al." is never used in the bibliography, even if there are 100 authors.

MP: problem connecting paths.
by Fabrice L 20 Dec '21

20 Dec '21

Dear list, I have a problem connecting path with the operator « & » (page 16 Metafun manual). The problem is illustrated by the code (and the joined PDF) which follows. I draw random cycled forms (left part of the figure) and when they interact, they are modified to « fit together » (right part of the figure) . When building these new forms, I connect paths (usually two or three depending on position 0 of the path); the last point a path is the same as the first point of the next path ; for exemple, to modify the blue circle, named « circleA », I take the circle A from P1 to P2, then a segment from P2 to P1 and cycle to have a closed path. So I should be able to do : newcircleA := circleA cutbefore P1 cutafter P2 & (P2 -- P1) & cycle ; The « & » operator is supposed to work (if I understand correctly) in this case, but I have this error message : "! Paths don't touch; `&' will be changed to `..’." Which I do not understand since the paths « touch ». There was a similar question last year, without a clear answer (« METAPOST subpath rounding issue »https://www.mail-archive.com/ntg-context@ntg.nl/msg94294.html). A solution is to ignore the repeating points : newcircleA := circleA cutbefore P1 cutafter P2 -- (P2 -- P1) -- cycle ; but this new shape has 9 points instead of 7. The problem is that I do these operations a number of times, and the length of a path (in the number of points) is increasing and cause trouble when I look for intersections with others shapes. Here is the MWE: \startMPpage path circleA , circleB ; pair P[]; circleA := fullcircle scaled 1in randomized 3 ; circleB := fullcircle scaled 1in randomized 3 shifted(0.3in,0.3in) ; draw circleA withcolor blue ; draw circleB withcolor red ; P[1] := circleA intersectionpoint circleB ; dotlabel.lft("$P_1$",P[1]) ; dotlabel.rt("$\blue\tfx P_0^A$",point 0 of circleA) ; P[2] := reverse(circleA) intersectionpoint circleB ; dotlabel.rt("$P_2$",P[2]) ; dotlabel.rt("$\red\tfx P_0^B$",point 0 of circleB) ; path newcircleA , newcircleB ; % newcircleA := circleA cutbefore P1 cutafter P2 & (P2 -- P1) & cycle ; % previous line gives an error : % "! Paths don't touch; `&' will be changed to `..'." newcircleA := circleA cutbefore P1 cutafter P2 -- (P2 -- P1) -- cycle ; newcircleA := newcircleA xshifted 2in ; draw newcircleA withcolor darkgreen ; newcircleB := (circleB cutafter P1) -- (P1 -- P2) -- (circleB cutbefore P2 ) & cycle ; newcircleB := newcircleB xshifted 2in ; draw newcircleB withcolor black ; drawpoints newcircleA ; drawpointlabels newcircleA ; \stopMPpage I would appreciate any help ! Thanks ! Fabrice.

Gap in rows if tabulate includes a startitemize
by Jorge Manuel 20 Dec '21

20 Dec '21

Dear Sirs I try to tabulate information in two columns: in the first a have a text sentence in the second I need to include a list of itens. My approach is like this: \starttabulate[|p(4cm)|p|] \FL \NC Objetivos \NC Estratégias \NC\NR \LL \NC Melhorar a qualidade do sucesso educativo \NC \startitemize \item one \item two \stopitemize \NC\NR \HL \stoptabulate On some cases the text and the list are correctly confined to the limits (\LL and \HL). But, in other cases, in the second column is inserted a gap (see the attach). How can I fix this. Thanks in advance. Jorge Magalhães Jorge Magalhães
