Both pdfinfo & exiftool have trouble with 1.0.4 but works with 1.0.3
by Ramkumar KB 13 Aug '21

Hi, We use PDF tools like mutool, pdfinfo (from poppler) and exiftool in our workflow (once the PDFs are created by ConTeXt). But looks like we have hit upon some regression issue between 1.0.3 and 1.0.4 versions. Both pdfinfo (from poppler) and exiftool are able to read PDFs created from 1.0.3 but have trouble reading PDFs created with 1.0.4. Please see below logs for details. Our 1.0.4 is from April-2021. We will try to upgrade to the latest 1.0.4 and try again. mtx-context | ConTeXt Process Management 1.04 mtx-context | mtx-context | main context file: /ConTeXt/apr2021/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2021.04.21 11:39 mtx-context | main context file: /ConTeXt/apr2021/tex/texmf-context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2021.04.21 11:39 mtx-context | ConTeXt Process Management 1.03 mtx-context | mtx-context | main context file: /ConTeXt/sep2020/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2020.09.20 23:02 mtx-context | main context file: /ConTeXt/sep2020/tex/texmf-context/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2020.09.20 23:02 *====pdfinfo (from Poppler)====* ~/TeX$ pdfinfo Hello-world_1.0.4.pdf Syntax Error: Missing 'endstream' or incorrect stream length Syntax Error: Missing 'endstream' or incorrect stream length Title: Hello world!

15th International ConTeXt Meeting (registration closes Aug 22)
by Taco Hoekwater 13 Aug '21

13 Aug '21

Hi all, There is still room for some extra participants for the ConTeXt meeting in Bassenge, Belgium from Sept 20 to Sept 25. Despite the still somewhat lingering situation wrt COVID-19, we are now certain that the meeting can and will in fact take place in person. Hurrah! Even if we still have room by then, registration will close on Aug 22, because by that time we need to make final arrangements for T-shirt printing and catering. So if you are still on the fence about attending, do not wait too long! Also remember that it is possible for ConTeXt Group members to attend online-only for free. That is less than ideal because you cannot join us for a drink and a chat, but it gives you bragging rights for attending, and you will get a T-shirt as well ! (if you register before Aug 22) You can easily become a member of CG by filling in the form at https://group.contextgarden.net/register.shtml Besides being able to register for the online portion of the upcoming meeting, you will also receive the nicely printed ConTeXt journal, and additionally you will help the ConTeXt Group to do more for the community in the future. Even if you are not going to attend the online meeting, we think becoming a CG member is a great idea! More that fifty people have joined already! To see more details about the upcoming meeting, see the website at https://meeting.contextgarden.net/ In other news, there is now a provisional programme page: https://meeting.contextgarden.net/2021/programme.shtml I can't wait to see (some of) you in person in Bassenge!

Footnotes in columns

I can no longer print the footnotes when I using columns in LTMX. If I remove the \{start|stop}columns, it works fine. This works on my old MKIV 2018.07.02 14:39 version. \setupcolumns[n=2,rule=off,balance=no] \starttext \startcolumns \input ward\footnote{A small footnote here} \stopcolumns \stoptext Context Version: 2021.01.24 16:07 Clyde

Conditional formatting with *frontpart, *bodypart, *backpart modes
by Joey McCollum 13 Aug '21

13 Aug '21

Hi, I was curious about the possibility of handling general formatting settings (e.g., page layout, headers and footers, page numbering, alignment, default body font assignment, etc.) conditionally for front, body, and back matter using modes. According to the wiki page at https://wiki.contextgarden.net/Modes, this should be doable with blocks like \startmode[*frontpart] ... \stopmode, but even in the following minimal example, the conditional formatting isn't getting applied: ``` \startmode[*frontpart] \setupbodyfont[modern, 12pt] \stopmode \startmode[*bodypart] \setupbodyfont[pagella, 12pt] \stopmode \startmode[*backpart] \setupbodyfont[termes, 12pt] \stopmode \starttext \startfrontmatter \input knuth\par \stopfrontmatter \startbodymatter \input knuth\par \stopbodymatter \startbackmatter \input knuth\par \stopbackmatter \stoptext ``` Is there something obvious that I'm missing? Or is there a different recommended approach to conditional formatting by front/body/back matter division? Thank you! Joey

Does anyone know what is wrong here or what am I missing? Many thanks for your help in advance, Pablo -- http://www.ousia.tk

space before section titles sometimes disappears in grid mode
by Henning Hraban Ramm 12 Aug '21

12 Aug '21

E.g. in CG journal, there are usually 3 blank lines before a section title. Most of it is single column and without grid, no problem there. But some articles use columnsets and are therefore in grid mode. Sometimes the space before the section title disappears completely, so that it is glued to the previous paragraph. If I include \startlinecorrection in "before" of \setuphead[section], in front of the \blank, the space is only reduced by 1 line, but I get the space also at the top of a column (or at the start of the article). If I put \startlinecorrection after \blank, the space disappears the same as without linecorrection. \setuphead[section] [before={\startlinecorrection\blank[BigCGblank]}, after={\stoplinecorrection\blank[CGblank]}, grid=both, ] It happens reproducably if there is a float before \startsection, but sometimes I can’t find a reason. In the other magazine I’m typesetting ATM, I get the same problem. No columnsets involved in that case, but still in grid mode. There I can "fix" it with some \blank[3*line], but it doesn’t help in the floats case. Hraban

Vertical offset in framedtext has changed
by Christoph Reller 12 Aug '21

12 Aug '21

Hi, Somewhere between versions 2021-07-06 and 2021-07-30 the vertical top-offset in framedtext has changed. Consider the MWE: \starttext \startframedtext Bla \stopframedtext \stoptext Output 2021-07-06: [image: FramedText-ConTeXt-2021-07-06.png] Output 2021-07-30 (and later): [image: FramedText-ConTeXt-2021-07-30.png] Is this a regression? Cheers, Christoph

Different in-text and list citation renderings
by Joey McCollum 10 Aug '21

10 Aug '21

Hi, I'm currently working on implementing a new citation rendering for SBL style. One of the challenges of this style is that it specifies slightly different rules for citations in the text (which are generally expected to look like citations made with the "entry" alternative) and entries in the final list of publications. The two most common differences are (1) Authors in the in-text citation are printed in normal form (i.e., first name followed by last name), while authors in the list citation are printed in inverted for for the first author and normal form for all subsequent authors. (2) Most fields in the in-text citation are separated by commas, while the list citation uses periods in these places. Is there already a mechanism for handling this for another citation style? And if not, could anyone offer a suggestion on how I might go about implementing separate rules for in-text citations and list citations? Thanks! Joey

ConTeXt exporter for Org Mode
by Jason Ross 10 Aug '21

10 Aug '21

Hello, I have developed a ConTeXt exporter for Org Mode. It is available at https://github.com/Jason-S-Ross/ox-context The exporter provides custom environments for each Org Mode entity in an effort to make customization easier, in contrast to the Pandoc exporter which uses built-in environments for document elements. I appreciate any feedback. Thanks, Jason
