mkiv MathML bug?
by Duncan Hothersall 27 Jun '19

27 Jun '19

I'm not sure this is something more general in the MathML module or if it's specific to the vertical bar in this particular context, but here is a minimal example showing that the "=0" at the end of the equation is disappearing: \usemodule[mathml] \starttext \xmlprocessdata{}{<imath> <math xmlns='http://www.w3.org/1998/Math/MathML'> <mi>A</mi> <mfenced open="(" close=")" separators=""> <mi>B</mi> <mo>|</mo> <mi>C</mi> </mfenced> <mo>=</mo> <mn>0</mn> </math> </imath>}{} \stoptext And here is a workaround using <mtext> instead of <mo> for the vertical bar which makes the "=0" magically reappear again: \usemodule[mathml] \starttext \xmlprocessdata{}{<imath> <math xmlns='http://www.w3.org/1998/Math/MathML'> <mi>A</mi> <mfenced open="(" close=")" separators=""> <mi>B</mi> <mtext>|</mtext> <mi>C</mi> </mfenced> <mo>=</mo> <mn>0</mn> </math> </imath>}{} \stoptext Flagged up mainly in case it is a bigger problem than just vertical bars in this specific context. Thanks, Duncan

Strange behavior in somewhat complex layout
by Andres Conrado Montoya 27 Jun '19

27 Jun '19

Hello list, I'm trying to make something using bits and examples found here and elsewhere, but I'm hitting a wall. I know there's a flawed logic in my approach, but I can't figure it out. Any help is appreciated. Expected behavior of the following MWE: When starting a new chapter, check if the page is even (left page), if so, fill it with color, and start the chapter in the next odd page (right page), removing the header but leaving the footer in that start-chapter page; and if this is a start-chapter page, use a specific graphic overlay for the page, but if if not (if its a regular page), use another graphic. Result: The header still appears in the start-chapter page, if it comes after the color filled page. But, if the start-chapter page comes after a regular (even) page, everything works as expected (no color-filled page, no header in the start-chapter page). MWE: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% START MWE \definecolor[rojo][h=ED553B] \definehighlight[rojo][color=rojo] \startMPinclusions numeric u ; u := 1.125pt ; numeric i ; i := 0.125in ; string prevChapterTitle, currentChapterTitle; prevChapterTitle := ""; currentChapterTitle := ""; \stopMPinclusions \startuseMPgraphic{page:background} StartPage; currentChapterTitle := "\namedstructurevariable{chapter}{title}"; if currentChapterTitle <> prevChapterTitle : fill (topboundary Page -- cycle) enlarged(0,8i) shifted (0,-4i) withcolor transparent(4, 0.2, \MPcolor{rojo}) ; fill (bottomboundary Page -- cycle) enlarged(0,1u) shifted (0,6i) withcolor \MPcolor{rojo} ; prevChapterTitle := currentChapterTitle ; else: fill (topboundary Page -- cycle) enlarged(0,0.25u) shifted (0,-7i+3u) withcolor \MPcolor{rojo} ; fill (bottomboundary Page -- cycle) enlarged(0,0.25u) shifted (0,6i) withcolor \MPcolor{rojo} ; fi; StopPage; \stopuseMPgraphic \defineoverlay [chapter:background] [\useMPgraphic{page:background}] \setupbackgrounds[page][background=chapter:background] \definepagebreak[firstpagebreak][yes,header] \startsetups [chapter:before] \doifoddpageelse {} {\pushbackground[page] \setupbackgrounds[page][background=color,backgroundcolor=rojo] \page[yes,right] \popbackground} \stopsetups \setuphead[chapter] [width=20em, before=\directsetup{chapter:before}, align={flushleft,nothyphenated,verytolerant}, style={\tfd\sansbold}, header=empty, page=yes, commandbefore={\blank[1.75in]}, after={\blackrule[color=rojo,height=4pt,width=6em]\blank[1.25in]}] \setuppagenumbering[alternative=doublesided,location=] \setupheadertexts [] [{{\small\sans\getmarking[chapter]}}] [{{\small\sans\getmarking[chapter]}}] [] \setupfootertexts [] [{\rojo{\small\sansbold\pagenumber}}] [{\rojo{\small\sansbold\pagenumber}}] [] \starttext \dorecurse{4}{% \startchapter[title={A chapter with a really long, long title}] \dorecurse{9}{\input{tufte}} \stopchapter \startchapter[title={A different chapter with a really long, long title}] \dorecurse{6}{\input{tufte}} \stopchapter} \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% STOP MWE Thank you for your time.

IEEE Citation Style
by Julian Gompper 27 Jun '19

27 Jun '19

Hello everyone, I am fairly new on the mailing list, so I apologize if this topic has already been talked about in the past. I am currently writing a technical documentation with ConTeXt, and I would like to use the IEEE citation style. As I have read on the wiki ( https://wiki.contextgarden.net/Bibliography_mkiv#rendering ) and in Chapter 4.2 of "BIBLIOGRAPHIES THE CONTEXT WAY" ( http://pragma-ade.nl/general/manuals/mkiv-publications.pdf ), only apa and aps styles are available as of now. I have found this file on github, although it does not seem to work and it was last created in July 2017 ( https://gist.github.com/adityam/afda949f76676055e7906679599ec937 ). Is there a more up-to-date version available, or should I try to make my own? Best regards, Julian

issue with italic correction (again)
by Pablo Rodriguez 27 Jun '19

27 Jun '19

Dear list, [sorry for insisting, but I have the impression that the previous version of this message went unnoticed.] I have the following sample: \def\DesiredFont{TeX Gyre Termes} \definefontfeature[italic][itlc=yes,textitalics=yes] \setupitaliccorrection[global, always] \definefontfamily [mainface] [rm] [\DesiredFont] \definefontfamily [mainface_corrected] [rm] [\DesiredFont] [features={italic}] \setupbodyfont[mainface] \setupitaliccorrection[global,always] \starttext \startbuffer[chars] \startTEXpage[offset=1em] \dorecurse{26} {\setupbodyfont[mainface]% [{\em \recurselevel}] [{\em \characters{\recurselevel}}] [{\em \Characters{\recurselevel}}] ({\em \characters{\recurselevel}}) ({\em \Characters{\recurselevel}}) \hfill \setupbodyfont[mainface_corrected] [{\em \recurselevel}] [{\em \characters{\recurselevel}}] [{\em \Characters{\recurselevel}}] ({\em \characters{\recurselevel}}) ({\em \Characters{\recurselevel}}) \par} \stopTEXpage \stopbuffer \getbuffer[chars] \def\DesiredFont{TeX Gyre Pagella} \getbuffer[chars] \stoptext This shows that sequences such as ({\em f}) are corrected with the closing parenthesis, but not with the opening one. Wouldn’t it be possible that italic correction could be enabled also before the italic glyph(s)? BTW, I wonder why the second definition of \DesiredFont doesn’t change the font for the buffer used after it. Many thanks for your help, Pablo -- http://www.ousia.tk

Re: [NTG-context] is it useful to use the option "--fonts=all" when running first-setup-sh?
by Andres Conrado 25 Jun '19

25 Jun '19

Tank you very much Pablo. I'll try that. They are proper latex fonts, tho, so I'm no sure that will do. I also have a background i humanities and book design, but I'm now making math books, go figure. It's very interesting from a typographic point of view. Now I'm more interested in seeing what happens with the last code I sent here, in another message... "Strange behavior in somewhat complex layout" Maybe nobody noticed it. I hope I can figure that out.

luatex-fonts-merged.lua broken?
by Ulrike Fischer 25 Jun '19

25 Jun '19

Hans, we think that luatex-fonts-merged.lua is broken: It contains in line 8594 return characters.indicgroups (from luatex-basics-chr.lua) and such a return statement is a problem in a merged file. -- Ulrike Fischer https://www.troubleshooting-tex.de/

Re: [NTG-context] ntg-context Digest, Vol 180, Issue 23
by Andres Conrado 25 Jun '19

25 Jun '19

Thanks, Pablo. I am assuming I need to have Utopia installed in my usual font folder. I tried with Erewhon (I have otf files for that) and it works. Thank you. In a related note, is there any reasonable way to use the latex math font *Math Times Pro 2* (https://www.pctex.com/mtpro2.html)? I know a latex user who bought that font and I wonder if I can convince him to get on the ConTeXt boat.

CrossWords Puzzles with context
by Jorge Manuel 23 Jun '19

23 Jun '19

After some attempts to build crosswords puzzles with context, I found this approach: 1) Create the puzzle with genxword https://github.com/riverrun/genxword <https://github.com/riverrun/genxword> 2) Edit the output table and change all {} to * 3) Save the table in a file (p.e. crosswords.txt) 3) In context use this script (Revised By Wolfgang Schuster) \startluacode context.startmidaligned() context.bTABLE( { rulethickness = ".25pt", width = ".8cm", height = ".8cm", align = "{lohi, middle}" } ) for line in io.lines("crosswords.txt") do for w in (line ..

After some searching in the test suite I found the answer, which I'll put here in case someone else is searching for it, which is: \setuphead[section][sectionsegments=section] \setuphead[subsection][sectionsegments=section:subsection] which sets up sections to just be numbered with the section number instead of the part, chapter and section number, and sets up subsections to just be numbered with the section and subsection number. Now that I know how to do it I see mkiv is much cleaner on this code and the change gets reflected in tables of contents etc. This was much harder in mkii. Thanks again. Duncan

mkii to mkiv - section numbering with minimal example
by Duncan Hothersall 23 Jun '19

23 Jun '19

Further to my previous query about updating from mkii to mkiv, I have solved some of the issues by trial and error but am beginning to identify the ones I can't resolve. My first minimal example is below. I want the sections and subsections not to prefix the part and chapter numbering, giving me this output: Part 1 Chapter 1.1 Section 1 Subsection 1.1 The line that used to achieve this result was \setupsection[section-3][previousnumber=no] and there was also \setuphead[section][partnumber=no,chapternumber=no] but neither of these seems to work in mkiv Minimal example: \setupsection[section-3][previousnumber=no] \setuphead[section][partnumber=no,chapternumber=no] \starttext \part{Part} Part \chapter{Chapter} Chapter \section{Section} Section \subsection{Subsection} Subsection \stoptext Many thanks for any pointers.

is it useful to use the option "--fonts=all" when running first-setup-sh?
by Andres Conrado Montoya 22 Jun '19

22 Jun '19

As the subject says. I've been experimenting with having a by-project context folder, so I can have a "frozen" version for each project. I see there's an option to install more fonts (including utopia, useful for a project I'm working on). However, I have no idea how to use these fonts. Are they available in mkiv? only for mkii? Do we have typescripts for those fonts? If so, how are they called? Are those fonts actually usable or are they just remains from a past era? Thank you for your time.

ConTeXt Group Newsletter
by Taco Hoekwater 21 Jun '19

21 Jun '19

In this newsletter: * 2018 journal progress * ConTeXt Meeting updates * Board elections * 2018-2019 membership invoices * Becoming a CG member * Membership promo action = 2018 journal progress = Production of the 2018 CG journal has finally started. With articles by Alan Braslau, Willi Egger, Hans Hagen and Taco Hoekwater, this will be a varied and even rather substantive issue. CG Members that attend the 2019 ConTeXt meeting will receive their copy at that meeting. The other CG members will find the journal issue in their mailbox about a week later. This is the first issue that will use the free IBM Plex Sans and IBM Plex Mono font families instead of the commercial Alwyn New and Inconsolata. See https://www.ibm.com/plex/ if you are interested in this new font family. = ConTeXt Meeting updates = We filled in the abstracts page with the parts of the program that we already know right now. We have quite a varied program already, and more is yet to come! The ConTeXt meeting is an excellent way to get help with any problems you may have in ConTeXt, to learn about future directions of ConTeXt and LuaTeX, or just to talk and have a drink with other ConTeXt users. You do not have to be a ConTeXt Group member to attend the meeting, but members do get a meeting fees discount worth more than the CG membership fees for a year. In fact, if you attend for the very first time, there is an extra discount for that as well. Oh, and there are now just nine days left for the early registration discount! For registration and other information, see the website at https://meeting.contextgarden.net/2019 The 13th ConTeXt Meeting is sponsored by Dante e.V (www.dante.de) and NTG (www.ntg.nl) as well as by Pragma ADE (Hans & Ton) and Bittext (Taco). We are very grateful to all our sponsors! = Board elections = The ConTeXt meeting is also the location of the annual CG membership meeting. This year, no less than four board members are forced to resign according to the bylaws. We are looking for CG members to help fill those spots in the board. If you are interested in joining the CG board, please send a message to any of the current board members and we will get in touch with you. We can really use the help! = 2018-2019 membership invoices = The invoices for the membership fees for the current period (2018-2019) will be sent out digitally early next week. = Becoming a CG member = Our official stated purpose: * to promote the ConTeXt typographic system; * provide its users with infrastructure and information; * support its development; * provide a platform for discussion of quality automated typography; * serve as a meeting place for people who want the best possible typography for the languages and writings of the world; * organise congresses and trainings for users and ConTeXt developers to meet; * provide financial support to those involved in documentation and ConTeXt development, including through their participation in conferences; * produce and sell printed materials on ConTeXt; * sell advertising items for ConTeXt. The more members we have, the more we can do. If you are not a member already, please consider registering at https://group.contextgarden.net/register.shtml Membership fees are €40 per year for normal members, €20 for students, and €200 for institutions and corporations. = Membership promo action = ConTeXt Group currently has close to 50 members. We have in fact been close to 50 members for a few years now, but we never seem to actually reach that number. So as a special promotion, the 50th active member will have their meeting fees waived for their first membership period (2018-2019 or 2019-2020 at your option). = That’s all for now = Keep happy ConTeXting! Best wishes, Taco

19 Jun '19

Dear list members, I would like to add a tag to a block so I can easily select a few blocks and print them in another chapter. In the below MWE I would like to print the normal (non-tagged) block in the first chapter. The second block with the tag [exam] should not be processed in the first chapter and only appear in the second chapter. According to the wiki and reference manual it should be possible using either \useblocks or \selectblocks but I can't get it to work. Who can help me out?

XML Export: Suppressing Presentation Forms in Arabic Script Fonts
by Hamid,Idris 19 Jun '19

19 Jun '19

Dear gang, Just documented the following in the wiki: https://wiki.contextgarden.net/Export#Suppressing_Presentation_Forms_in_Ara… For those who use certain commercial Arabic-script fonts with XML export: In the course of ConTeXt processing, many standard codepoints from the U+600 block are substituted with those from a subset of Presentation Forms B, which breaks the input in critical ways. Many thanks to Hans for pointing out this simple way to solve the issue. For details, see the link above.

newlines in return Lua string
by Hans van der Meer 15 Jun '19

15 Jun '19

From \ctxlua{tex.print(hvdm.myluacall("\xmlatt{#1}{argument}"))} Lua returns a string containing newline characters '\n'. In ConTeXt this returned string is printed as one line, the embedded newlines are not honoured. I thought to replace with \crlf in this manner: string1 .. "\\crlf" .. string2 but the returned \crlf are not executed as such. How to force \crlf's in the executed return? dr. Hans van der Meer

aligning rotated text in a natural table

I am trying to align rotated text horizontally and vertically in a table cell. Vertically is no problem, horizontally it fails. Non-rotated text is, of course, fine. What can I do to fix the problem?

mkii to mkiv - what an ancient user needs to know
by Duncan Hothersall 12 Jun '19

12 Jun '19

Hi all. Long-time user but haven't posted in a long while... After many happy years of running a mkii set up I am finally facing the fact that time has moved on and upgrading to mkiv. I understand the biggest change needed to my sources is in the fonts handling, but I am getting a few other problems with things like chapter/sectioning setups that I can't see mentioned in https://www.contextgarden.net/MkIV_Differences I was wondering if there exists a comprehensive "what you have to change in your sources to move from mkii to mkiv" document anywhere or, failing that, if anyone can offer guidance on what has changed in the chapter/sectioning setups code between the two. Apologies for not supplying an example of code - I'm not yet at the point that that's possible. Any help much appreciated. And hello to anyone who remembers me from fifteen plus years ago! Duncan

CMYK Color profile
by Benjamin Koppe 02 Jun '19

Hello everyone, I'm about creating a DIN Lang Folder brochure with ConTEXt. I got everything set up the way I'd like it to. Now that I'm done with the work, I've been told the output pdf should have a CMYK Color profile embedded for the on demand printing service to be able to deal with the file... I am unsure what steps I have to take to make my output pdf compliant with CMYK. I don't even know how I could verify it does indeed have CMYK. Evince doesn't seem to show that info... So if anybdy of you could give me some hints, that's be wonderful. Cheers De Benny

XML in latest betas (MkIV & LMTX)
by Pablo Rodriguez 02 Jun '19

02 Jun '19

Dear list, I have just installed latest betas for both MkIV and LMTX. Compiling exactly the same XML sources (a book on ConTeXt in Spanish), MkIV needs 40s and LMTX more than 52s. This is the first time I get such a difference in compilation times. I’m afraid I can’t be sure that output is the same, since different spacing gives different page numbers. I wonder whether this might be an issue. Many thanks for your help, Pablo -- http://www.ousia.tk

I adapted the code a bit (next beta) - a threshold is a pct of the font size (was designsize) - i now default to 5pct which is .5 pt for a 10 pt font - i also limit to max 10 pct and issue a warnign when > 5pct - lucida might come out better with values < 5 I'm still considering to default to just .5pt but that is something I need to discuss with Wolfgang. Also a matter of testing. These thresholds also relate to the size of the pdf file (small values means larger files). Now, another thing to keep in mind is that each expansion change (in one line there can be different expansion factors used) also triggeres a resync.

chapter-number prefixes on figure, etc, numbers, even in unnumbered section appearing in TOC
by Sanjoy Mahajan 31 May '19

31 May '19

Dear List, The following, it seems, is a recurring question, which I had hoped to solve by digging in the test suite <https://wiki.contextgarden.net/Test_suite> -- but no luck. The problem is to have figures, list items, problems, etc. numbered with a chapter prefix (e.g. Figure 7.18) even in unnumbered sections that appear in the TOC. 1. Using \subject as the section command, the figure number is correctly prefixed, but the section itself doesn't appear in the TOC. 2. Using \section, the figure number is also correctly prefixed, and the section appears in the TOC, but the section gets numbered (e.g. Section 2.7). In one of the earlier threads, which are "Prefix for figure number lost in unnumbered subsection" <https://ntg.nl/pipermail/ntg-context/2015/082094.html>, "Unnumbered subject in TOC, numbered exercises in text" <https://ntg.nl/pipermail/ntg-context/2015/083710.html>, and "incrementnumber vs. prefixsegments" <https://ntg.nl/pipermail/ntg-context/2012/069765.html>, Hans suggested looking in the test suite for fine control of the prefix segments. I have done that, and the best MNWE that I can come up with is a modification of doc/context/tests/mkiv/sections/figures-001.tex in the test suite (see code below), but it also fails: * When incrementnumber=list (as in the code), the TOC lists that section, but the figure 5 doesn't get a chapter-number prefix. * When incrementnumber=no (recreating \subject), the TOC is not correct, but figure 5 gets its prefix. * And wWhen incrementnumber-yes (recreating \section), the TOC lists that section, but the section gets a number. Is there a modification to what I tried that gets all the aspects right (TOC entry, unnumbered, chapter prefix on figures, etc. within)? -Sanjoy The code: \setupcaption[figure][way=bytext,prefixset=1:2] \definehead[unnumberedsection][section] \setuphead [unnumberedsection][incrementnumber=list] \starttext \placelist[chapter,section,unnumberedsection] \chapter{One} \placefigure{one}{1} \section{Two} \placefigure{two}{2} \chapter{Three} \placefigure{three}{3} \placefigure{four}{4} \unnumberedsection{Four} \placefigure{five}{5} \stoptext

Wiki update
by Taco Hoekwater 31 May '19

31 May '19

Hi all, Not sure how many of you remember this, but at the Kalenberg meeting in 2016 there was this talk: =========== Setups Wolfgang Schuster (and Hans Hagen) The user interface is described in xml files but the actual descriptions lagged behind development. Wolfgang spent a considerable amount of time to describe all commands in detail and we updated the descriptive format in the process. The rendering was partly redone, as was the help system and scripts that use this information. =========== Since then, nothing much had been done with those updated xml files, which is a big shame considering the enormous amount of work that went into the process. But recently we have been discussing the wiki and (especially) the sorry state of the reference portion of that. At some point, I realised that we could rather easily combine the new xml interface files with a small wiki extension, such that the wiki has easy access to the latest and greatest command list. =========== From now on, when you are editing the wiki (especially the /Command/CMD pages), you can use <syntax>CMD</syntax> to output the formal table of arguments for that CMD (omit the backslash) For example, <syntax>section</syntax> outputs a table with the formal calling convention(s) for the \section command. Multiple tables actually, as it also outputs the alternative calls with different arguments, and it outputs the definition of the internal \*section* command, of which \section is an instance. (The parents of instances are printed in a slanted font). There are 2035 normal commands and 373 instances in the database, essentially covering all the style- and document-level commands in ConTeXt. I’ve decided not to add the low-level system commands because (apart from perhaps a few special cases) these do not belong in general user documentation. =========== I have not auto-replaced any of the handcrafted command page syntax tables in the existing wiki pages, because quite often the current syntax table has manual additions explaining various options. In the formal version these are obviously not present, and I did not want to remove any of that extra information. Anyway, the nice thing about this new wiki plugin is that if you want to create a page for a specific command that is not in existence right now, it is a simple matter of going to the expected url, and creating a page with just a Syntax heading and a <syntax> tag. For example (created a minute ago): url: https://wiki.contextgarden.net/Command/setupdescription content: == Syntax == <syntax>setupdescription</syntax> Thanks go to Wolfgang for all the hard work! Best wishes, Taco

Extend figure to margin, or extend figure from margin to text
by Zhichu 30 May '19

30 May '19

Hi everyone, I am writing a book, in which all figures are placed in the margin. But some graphics are too big to fit in the margin. I was wondering whether there's an elegant way to use some room of the text body? The output is close to the following, but the caption should be as wide as the figure and the part in the margin should not affect other marginal notes: ==================================== \showframe \starttext Hello\inright{Very very very long test notes.}, world! \startplacefigure [reference=fig:whatever, title={Test figure.}, location=outer] \hbox{% \framed [frame=on% ,offset=0pt% ,width=\dimexpr\rightmarginwidth+\rightmargindistance\relax ,height=\rightmarginwidth ]{Extended Part}% \framed [frame=on% ,offset=0pt% ,width=\rightmarginwidth ,height=\rightmarginwidth ]{My Figure Here}% \kern-\rightmargindistance \kern-\rightmarginwidth } \stopplacefigure \input knuth \stoptext ==================================== Lua codes are also welcomed.

Please note that to reproduce the error with the context version of texlive 2019 the first lines must be uncommented due to a bug in the newer version of tikz.

Could you suggest any workaround? If not I'll file a bug with pgfplots. Thank you in advance, LD

Itemization formatting
by Taco Hoekwater 29 May '19

29 May '19

Hi all, I must be getting old :( It used to be that I could get ConTeXt to do what I wanted, but that is increasingly getting harder. Current problem: I would like to have itemizations that behave like in this dummy ascii formatting: * Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec dapibus turpis et nulla venenatis tincidunt. Curabitur sit amet vehicula nisi, sit amet and so far it has been impossible for me to set up \setupitemize to do what I want. In descriptive text, what I want is: 1. some global indentation to the left and/or right. That is what the margin= key does 2. the symbol (or number) typeset in a specific width. That is the width= key 3. some distance between the number box and the following text. That is the distance= key 4. on line 2 and forward to the end of the item, I want a *different* indentation from the first item line. In this particular case, I want no extra indentation except for ‘margin’, but in other cases I may like either more or less indentation than on line 1 of the first para of the item. The desired effect is simple achieve with primitive operations, but I would like the input to look nice (not to mention that I do not want to loose options for cross-referencing etc). \setupitemize[option=intext] is nearly right for this case (with indentation equal to the left margin), so I assumed I would be able to tweak that. But the problem there is that while it does 2-4, it ignores the extra indentation required for nested itemizations (it even ignores explicit margin= settings for the nested level). After fighting with this for hours, I am nearly ready to give up. Anybody have any idea how to get itemizations to do what I want? MWE attached. Best wishes, Taco PS It seems that “indentnext=no” does not work for nested itemizations?

bookmark expansion again

But bookmarks alone (when aren’t prerolled. From strc-sec.mkiv, I see that prerolling is only applied to \currentstructuretitle when \currentstructurebookmark is empty. Would it be possible that \currentstructurebookmark could have prerolling when it is different from \currentstructuretitle? Sorry for insisting, but I need this to avoid having "main:345{/h2}" as bookmark for some chapters. Many thanks for your help, Pablo -- http://www.ousia.tk

two (2) questions about footnotes
by Thomas A. Schmitz 27 May '19

27 May '19

Hi all, I have two questions/problems about footnotes. Here is a minimal example, which does not compile in this form: \unexpanded\def\MyRule{\blackrule[width=\textwidth,height=3pt]} \setupfootnotes[rule=\MyRule] \starttext Test1: \index{Adam}Adam.\footnote{Test2: \index{Eve}Eve.} \page \placeregister [index] \stoptext (1) In my current project, the publisher wants the rule separating text and notes to extend across the entire text width. I found the \blackrule command and its use in the setup on the mailing list, many years ago, proposed by Steffen Wolfrum, but it doesn't work (anymore?); I get "tex error on line 3 in file /tmp/test.tex: ! Missing \endcsname inserted." Any hints? (2) Again, something that has been asked on the mailing list, but not received any replies: would it be possible to have the index report that "Eve" occurs inside a footnote? So it says "Eve 1 n. 1" or something like that? Thanks a lot, and all best Thomas

Fontloader
by Herbert Voss 26 May '19

26 May '19

I had a problem with the fontloader and luatex. I tried to run my test document with context (latest minimal) to compare the output, but I failed. The font LibertinusKeyboard-Regular.otf https://ctan.org/tex-archive/fonts/libertinus-fonts/ uses ligatures especially for the keys above 0xFFFF However, I cannot get it run with latest mkiv. It is no problem with xetex. It should print only the five keys and not the ones for every single letter.

XML export: basic questions
by Procházka Lukáš Ing. 22 May '19

22 May '19

Hello, suppose having "Main.mkiv": ---- \setupbackend[export=yes] \starttext \startsection[title={Sec},MyPar=MyVal] \input knuth \stopsection \stoptext ---- Some questions concerning XML export: 1. Normally, with \setupbackend[export=yes], Ctx creates "Main-export" directory containing (among others) Main-raw.xml, and Main-tag.xhtml and some subdirs. Is there a way to tell Ctx to produce just one XML file with a prescribed name which wouldn't be placed in any subdir? In my case - to produce "Main.xml" (instead of "Main-export/Main-raw.xml"), other files to be omitted? 2. Is there a way to export user parameters used in \section? In my case: \startsection[title={Sec},MyPar=MyVal] uses user parameter "MyPar" with value "MyVal", but "MyPar" is not transmitted into XML; the goal is to have <section detail="section" chain="section" implicit="1" level="3" MyPar="MyVal" > which would allow some filtering when reprocessing that XML. - Or is there another way, like enclosing into a user tag: \starttag[MyTag] \startsection[title={Sec},MyPar=MyVal] \input knuth \stopsection \stoptag which would export into: <MyTag> <section detail="section" chain="section" implicit="1" level="3" MyPar="MyVal"> ... </section> </MyTag> Best regards, Lukas -- Ing.

Creating one's own style

Questions on columnsetspan (and grids and backgrounds)
by Mikael P. Sundqvist 18 May '19

18 May '19

Hi, I have for some hours tried to understand how to work with columnsetspans (I'm trying with an updated lmtx), and have some questions. 1) Is it only the floats that has the long list of placement options (given on p. 18 in the columnsets manual), or should they also apply to columnsetspans and columnsetareas? (I cannot get it to work with "default=fxtb:2*10" and similar options for other elements than floats). It would be useful to have it for other type of elements as well. 2) What is the current correct way to get back on grid after formulas? The only key that had lead me to something that seems to work in \setupformulas is "option=depth". Is that the way to go? 3) This is a bit unrelated, but is it possible to set page backgrounds on specific page. Something like \setupbackgrounds[page][page=3, ...] (I cannot find any keys for this in setup-en.pdf). Right now I can set it for an odd and an even page, but then if I want a background on the page after that, I have to put that code at the place where it will be used. (I got an error with \startpostponing[+1] ... \stoppostponing) 4) To be a bit more concrete on the first issue: In the example below, how can I place the columnsetspan at the bottom right? Second and third column, 10 lines down? I attach the result of running this file. /Mikael \setuplayout[grid=yes] \showgrid \definecolumnset[three][n=3] \definecolumnsetspan[two][ n=2, background=color, backgroundcolor=lightgray, ] \starttext \startcolumnset[three] \samplefile{knuth} \startcolumnsetspan[two][default=btrl] \samplefile{ward} \stopcolumnsetspan \dorecurse{5}{\samplefile{knuth}\par} \stopcolumnset \stoptext

readposition() in mkiv font-dsp.lua
by Dohyun Kim 17 May '19

17 May '19

Hi, I am using luaotfload.sty in TexLive 2019, that is latex. On my mac, everything is flawlessly working. But I've heard from somebody that NotoSansCJKkr-Regular etc fonts are not usable on Windows machine; so I tested on 32-bit Windows 10 virtual machine with small memory (2GB) and it was really unusable. I did some digging into the source code of luaotfload package. Now I have a guess that readposition() in font-dsp.lua might be the culprit. For instance, when format == 0x04 and the result of readshort(f) == 0, then the return value of the function is currently "true". After it has been changed to "false", NotoSansCJKkr fonts are working quite well on 32-bit Windows. With the same changes of readposition() on my 64-bit Mac, the elapsed time for making cache file of NotoSansCJK fonts has been dramatically reduced: from 25 seconds to 10 seconds. And the resulting cache file is perfectly the same as before. So I would like to suggest those return values to be changed to "false". Certainly, I do not know much about opentype spec, so I might be wrong and there could be good reasons for current code state. Regards, -- Dohyun Kim Seoul, Republic of Korea

xmldoif, \startSECTION ... \stopSECTION and \setuphead

Strange behavior concerning pdf-output of externalfigures

I'm experiencing the artefacts with some figures which are all several years old. Until now it never happened in conTeXt programs. Because I installed a new OS (LinuxMint) on my workstation at the same time I tried 3 pdfviewers (okular, evince, xpdf) all with the same result.

XML roundtripping
by Denis Maier 16 May '19

16 May '19

Hi everyone I am setting up a workflow for a journal where we will be using JATS XML as an input format. PDFs should be typeset via ConTeXt. Is roundtripping possible with ConTeXt? I will perhaps need to write page numbers back to a XML file (either to the input file or to a new file.). Best, Denis

Bug or not?
by Hans van der Meer 16 May '19

16 May '19

There is an interaction in the placement of float captions when their width is set and background coloring switched. Minimal example included here, the jpeg is arbitrary of course. Output shown. Setting the width of the caption effectively shifts the caption to the left. See the change between the last two floats where [background=] changes the game. I wonder, is this intended behaviour? Or should one expect something different? \starttext Testing figure captions with \tex{setupframed[background=]}\blank \setupframed[background=color,backgroundcolor=yellow] \placefigure[][]{\tex{setupframed[background=color]}}{\externalfigure[test.jpg]} Add \tex{setupcaption[align=middle,width=\makeupwidth]} as setting here:\par \setupcaption[align=middle,width=\makeupwidth] \setupframed[background=color,backgroundcolor=yellow] \placefigure[][]{\type{\setupcaption[align=middle,width=\makeupwidth]}}{\externalfigure[test.jpg]} \setupframed[background=,backgroundcolor=yellow] \placefigure[][]{\tex{setupframed[background=]}}{\externalfigure[test.jpg]} \stoptext dr.

issues with rotated paper size
by Pablo Rodriguez 15 May '19

15 May '19

Dear list, I have the following sample: \setuppapersize[A4, landscape][A4, 90] %~ \setupinteractionscreen[option=max] \showframe \starttext \showlayout \stoptext For some reason, the page is displaced from the paper bottom. And if fullscreen is set, the real paper size is a square. I think this may be a bug. Could anyone explain me what I’m doing wrong or confirm the issue? Many thanks for your help, Pablo -- http://www.ousia.tk

filling page to bottom
by Hans van der Meer 15 May '19

15 May '19

I find that the current (default) settings tend to break pages early, leaving a fairly large amount of whitespace at the bottom of the pages. Obviously in order to avoid breaking paragraphs or to avoid small parts of a paragraph at the top of the page. What parameters do I have to tweak to fill the pages more completely? Because I planned already to examine all pages individually for their appearance, inserting breaks by hand is not the problem here. dr. Hans van der Meer

Split up PDF a certain
by Denis Maier 15 May '19

15 May '19

Hi, is there a way to split up a PDF a certain points, e.g. at every \startsection? (I am thinking of a way to produce both one PDF for a complete journal issue and for each individual articles. Or should I better use an external tool to post-process the resulting PDF?) Best, Denis

Compiling multiple files without master document
by Denis Maier 15 May '19

15 May '19

Hi, Currently it is possible to process a file with an external environment file specified via the command line. ``` context file --environment=mydefs ``` Very nice. Is it possible to process multiple files from the command line without a master document? Like so: ``` context file1 file2 file3 --environment=mydefs ``` Or should I just use `cat file1 file2 file3 > file` before processing? Best, Denis

Difference between the pagecolumns mechanism vs newcolumnsets/pagegrids?
by SPIT 15 May '19

15 May '19

Complete beginner with ConTeXt, just confused about the difference between the difference between mechanisms due to the similar naming? Is it just a difference in float handling?

\includeonly and ConTeXt components
by Denis Maier 14 May '19

14 May '19

Hi again, last question for the moment ;-) With LaTeX we can use `\includeonly` for partial compilation. The good thing is that we can still refer to labels from other files, have a complete TOC, and correct page numbers. In ConTeXt the project structure is supposed to be used for partial compilation. But it does not seem to have those features, right? Having correct page numbers across the individual components would be especially helpful. Any ways to get this? Best, Denis

Questions regarding project structure
by Denis Maier 14 May '19

14 May '19

Hi, I am just testing out the project structure. Let's suppose I have these files: - test_env.tex ``` \startenvironment * \setuphead [section] [textstyle=\bf] \stopenvironment ``` - test_project ``` \startproject * \environment test_env \product test_prod \stopproject ``` - test_prod.tex ``` \startproduct * \project test \startalignment[middle] HEY \stopalignment \component test_comp \stopproduct ``` - test_comp.tex ``` \startcomponent * \product test_prod % \project test_project % uncomment this to use the \section{Test} \input ward \stopcomponent ``` >From the documentation [https://wiki.contextgarden.net/Project_structure] I would assume two things 1. The environment should be used in the component via project=>product. 2. Everything in the product that is not in a component should be used in the component as well. Both assumptions seem not be correct. Any hints about this? Am I missing something? Am I doing something wrong? Or is there a bug somewhere? Documentation errors? Best, Denis

thumb index: \setlayer on every odd/even page?
by Henning Hraban Ramm 13 May '19

13 May '19

Hai, how must I setup layers that get repeated on every even/odd page? Or should I use \doifoddpageelse with \setlayer? Or do you have a different suggestion for thumb index “boxes”?

inserting figure labels
by Hans van der Meer 12 May '19

12 May '19

Placing a float figure with \placefigure[][]{labeltext}{\externalfigure[]} delivers a figure with a label like "Figure V.3 labeltext" (depending on the setup) Now I want to intersperse this with an \externalfigure[] not within a placefigure but still accompanied by a label in the current running series. For example an uninterrupted series of figure numbers with: \placefigure[][]{labeltext-1}{\externalfigure[figure1]} % -> Figure 1 labeltext-1 \externalfigure[figure-2] \macrocall{labeltext-2} % -> Figure 2 labeltext-2 \placefigure[][]{labeltext-3}{\externalfigure[figure3]} % -> Figure 3 labeltext-3 I could not find what macro to call as the instance for \macrocall. dr.

suggestions for \definefontfamily and \definefallbackfamily
by Pablo Rodriguez 12 May '19

12 May '19

Hi Wolfgang, as I reported the issue with the fonts and LMTX, I remembered two suggestions I wanted to post here. The first one is enabling the use of "method=uppercase" in \definefallbackfamily (to get fake caps, such as in https://mailman.ntg.nl/pipermail/ntg-context/2018/092878.html) The second feature is to enable \definefontfamily to load font files not part of the font database, the same way as \definefont is able to load them. Many thanks for your help, Pablo -- http://www.ousia.tk
