mp-geo Metapost package with ConTeXt
by Gavin 22 Oct '21

22 Oct '21

Hello ConTeXters, I’d like to use the mp-geo Metapost package with ConTeXt to draw simple globes viewed from various directions. The package is here: https://melusine.eu.org/syracuse/poulecl/mp-geo/ It looks like the last update was 2008 and I don’t read French, so I though my chances of getting anything to work were pretty small. However, I was pleasantly surprised that this MWE found the mp-geo package, the necessary Metapost files in the ConTeXt installation, and the data files. \starttext \startMPcode input mp-geo; figure(-10u,-10u,10u,10u); Mercator(3,48,30); fin; end \stopMPcode \stoptext While all of the files were found, it did not produce a globe. Instead I got an error complaining about an invalid character in the data files. This error is repeated for about 20 files (a small fraction of the total). I put the first error and its data file below. All the others are identical with different .dat files. Maybe it’s just an encoding mismatch or a hidden character I can easily delete or replace. On the other hand, maybe I shouldn't even be attempting this? 2008 is a long time ago in ConTeXt time. Feel free to tell me this project is crazy, but if you have an idea how I can make this work, I’d really appreciate it! It looks like a fun package. Thanks! Gavin Error Log: (This error log below is actually from running Metapost directly on just the .mp file with the metapost code above. This error log is slightly more clear in its formatting than the ConTeXt log, but contains the same information.) !

Short forms and abbreviations in bibliography
by Joey McCollum 11 Oct '21

11 Oct '21

Hi, It is a common practice to use short forms of titles for bibliographic entries after they are cited the first time. Another practice is to use abbreviations for journal names and book series (generally for citations in the text, but possibly also in the references list), with a separate "List of Abbreviations" provided to cross-reference the abbreviations and full names. I think that these practices could be accommodated with multiple bibliographies that contain short and long forms for corresponding entries, but I wanted to ask: is there a simpler or preferred way to do this in ConTeXt? To illustrate what I mean, the biblatex-sbl package ( https://github.com/dcpurton/biblatex-sbl) which implements the SBL citation style for (Xe)LaTeX, handles this using additional fields like "shorttitle," "shortjournal," and "shortseries," so for the BibTeX-style bibliographic entry @book{Blau2010, author = {Joshua Blau}, title = {Phonology and Morphology of Biblical Hebrew}, shorttitle = {Phonology}, series = {Linguistic Studies in Ancient West Semitic}, shortseries = {LSAWS}, volume = {2}, location = {Winona Lake, IN}, publisher = {Eisenbrauns}, year = {2010} } the initial in-text citation (in SBL style) would look something like Joshua Blau, *Phonology and Morphology of Biblical Hebrew*, LSAWS 2 (Winona Lake, IN: Eisenbrauns, 2010), while subsequent in-text citations would look like Blau, *Phonology*. A separate list of abbreviations would then list "LSAWS" alongside "Linguistic Studies in Ancient West Semitic" (and likewise for other journal/series abbreviations). Thank you! Joey

composing commands
by Hans Hagen 11 Oct '21

11 Oct '21

Hi, As I'm going over the commands in lmtx, I wonder if we should keep \c \d \k \r \u \v \" \' \` \^ etc ... the ones that make 'composed characters'. I think that anyone who needs them uses utf . They can be in (say) m-oldschool.mkxl or so. Objections? Hurt feelings? Sentiments?

one quick remark about textext.dflt (vs textext.dlft)
by Garulfo 05 Sep '21

05 Sep '21

Hi all, one remark, I was expecting to be allowed to use textext.dlft but finally the appropriate command appears to be textext.dflt which require to switch F and L letters. Is it on purpose ? would it make sense to have a dlft version to match LeFT ?

problem with MkIV/TeXlive/TEXMFCACHE
by rjhb＠bb-c.de 30 Aug '21

30 Aug '21

Dear experts, I want to use ConTeXt MkIV as supplied by TeXlive 2021. After installation, I ran "mtxrun --generate". I also tried "context --generate". Both create output in the wrong place. The TeXlive documentation says that ConTeXt uses TEXMFCACHE, which uses the default $TEXMFSYSVAR;$TEXMFVAR in my texmf.cnf. My TEXMFSYSVAR is /var/opt/texlive, but ConTeXt doesn't use it. Instead, it creates /opt/texmf-var and creates its output there. I don't understand why it used that path; I've never used or configured it. How can I convice ConTeXt to use TEXMFSYSVAR? Or is this a question for the TeXlive folks? Thanks for looking at this. Regards, Rainer

How odd; Then it must be related to my viewer here ... I was just surprised to literally see two different outcomes with the \startTEXpage and without. Maybe it has to do with some sort of "nesting" in the PDF that is not handled correctly at the PDF viewer's end. I'll test again on a different machine (and with the printing company) when I'm back to work. Thanks for having looked into it! > On Aug 30, 2021, at 10:50, Hans Hagen <j.hagen(a)xs4all.nl> wrote: > > attached is what i get and i see the green shading here > > > > ----------------------------------------------------------------- > Hans Hagen | PRAGMA ADE > Ridderstraat 27 | 8061 GH Hasselt | The Netherlands > tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl > ----------------------------------------------------------------- > <x.pdf><x.tex>

Best way to apply a fill-pattern to a closed shape?
by Ramkumar KB 30 Aug '21

30 Aug '21

Hello List, I have a use case to apply a particular pattern to a closed shape. I am using Metapost for the figures. After some research this package seems to quite good, in terms of having all the patterns normally used - https://ctan.org/pkg/minim-hatching But I could not figure out how to use this with ConTeXt. Or maybe there is already a better way to do this in ConTeXt and am missing that trick. Any tips would be really helpful. Thank you. Best regards, Ramkumar
