Regular online meet-up
by Henning Hraban Ramm 14 Dec '21

14 Dec '21

Hi all, already for a while I wanted to suggest a regular online meet-up, just to chat or discuss ConTeXt and the world. Participants of the just finished meeting already know the BigBlueButton “room”, and without the difficulty of a auditory in presence and a weak DHCP, we should have even less problems with it. I’d offer this monthly, 2–3 hours, and let’s see if it stands the test. Now, if you’d like to participate, which times would fit you (weekdays, daytime...)? Warm regards, Hraban

Hyphenation on digits
by Jairo A. del Rio 03 Nov '21

03 Nov '21

Hi, list. I want to know if ConTeXt provides an option to automatically hyphenate/break digits as if they were alphabetic characters. Example, in a narrow page I expect something like that (I've used (-) for an optional hyphen): *π = *3.141592653(-) 58979323846264(-) 33832795028841(-) 97169399375105(-) ... I found myself unable to read a satisfactory solution in the mailing list archive nor other TeX related resources. Maybe LMTX has some magic for that? Cordially, Jairo

Question on style-italic vs style=italicface
by Rik Kabel 24 Oct '21

24 Oct '21

Hello list mavens, What are the circumstances under which style=italicface should be used instead of style=italic. I note a difference when I define highlighting. I expected to see no difference in the line before and line after the hairline the example below, but see that italicface adapts to nesting, while italic does not: Are there other places where this makes a difference? \setupbodyfontenvironment [default] [em=italicface] %same with italic for this example \definehighlight [emIt] [style=italic] \definehighlight [emIf] [style=italicface] \definehighlight [emEm] [style=\em] \starttext {\em abc {\em def} ghi}: \type{\em} \emph{abc {\emph def} ghi}: \type{\emph} \emEm{abc {\emEm def} ghi}: \type{\emEm \definehighlight[style=\em]} \emIf{abc {\emIf def} ghi}: \type{\emIf \definehighlight[style=italicface]} \hairline \emIt{abc {\emIt def} ghi}: \type{\emIt \definehighlight[style=italic]} \stoptext -- Rik

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?

Addition of authortitle sorttype for bibliographies
by Joey McCollum 05 Oct '21

05 Oct '21

Hi, I've had to make another update to the general publications support code in order to implement a feature of the SBL rendering. Denis Maier has opened some issues on the context-sbl GitHub repo ( https://github.com/jjmccollum/context-sbl) to offer some helpful suggestions about needed features and bug fixes. One issue was that SBL should order list entries by author and title. Thankfully, there is already an authordate sortmethod defined in publ-aut.lua (probably to support the Chicago rendering), so I was able to use it as a template for the following authortitle sort sequence: ``` publications.sortmethods.authortitle = { sequence = { { field = "author", default = "", unknown = "" }, { field = "title", default = "", unknown = "" }, { field = "date", default = "9998-13-32", unknown = "9999-14-33" }, -- some specifications allow date instead of year, month, day { field = "year", default = "9998", unknown = "9999" }, { field = "month", default = "13", unknown = "14" }, { field = "day", default = "32", unknown = "33" }, { field = "index", default = "", unknown = "" }, }, } ``` I added this to publ-aut.lua because publications.sortmethods.authoryear is defined in that file, but if another location is more appropriate, then feel free to let me know, and I can move it! Otherwise, if this looks okay to include in a future update, then feel free to incorporate it! Joey

Dumb question about ligatures
by Bruce Horrocks 03 Oct '21

03 Oct '21

I'm using a TTF file that has no ligature capability as a built-in feature. It does however have glyphs for fi and fl but ConTeXt isn't substituting them. So the question is: what do I need to do to persuade ConTeXt to do fi & fl ligature substitution? — Bruce Horrocks Hampshire, UK

Blank line after \item: MkIV vs LMTX and how to properly get rid of it
by Vladimir Lomov 30 Sep '21

30 Sep '21

Hello. Consider the following small example: ------------------------------------ 8< -------------------------------------- \starttext \startitemize[n] \item \input tufte \item \placefigure[right,none]{}{\externalfigure[cow]}% \input tufte \item \blank[overlay]% \placefigure[right,none]{}{\externalfigure[cow]}% \input tufte \stopitemize \startitemize[n,intext] \item \input tufte \item \placefigure[right,none]{}{\externalfigure[cow]}% \input tufte \item \blank[overlay]% \placefigure[right,none]{}{\externalfigure[cow]}% \input tufte \stopitemize \stoptext ------------------------------------ 8< -------------------------------------- I see a difference in MkIV and LMTX work: - MkIV always put a blank line despite '\blank[overlay]' command; - with \blank[overlay] and 'intext' option LMTX clutters item label (number in this case). Q1: is this the expected behavior for MkIV and LMTX? I found a recipe with \blank[overlay] in the mailing list. Q2: is it expected that LMTX will clutter item label when I use \blank[overlay]? I suspect the answer is "yes" due to the option name. Q3: how to prevent blank line insertion in such case: an item with text framing a picture (on right side or on left side but the picture is below the item label)? --- WBR, Vladimir Lomov -- Without freedom of choice there is no creativity. -- Kirk, "The return of the Archons", stardate 3157.4
