Thanks! (I did find out about \startMPpage[offset=3pt], but that requires me to include my MetaPost file into an additional, somewhat superfluous TeX file. And for better editor support I prefer to edit the MetaPost in a .mp file, rather than embedded in a .tex.)

[NTG-context] How to add margin around standalone MetaPost?
Take the following MetaPost file: beginfig(0) ahlength := 20; linejoin := mitered; drawarrow origin--(40,0) withpen pencircle scaled 5; endfig; Render it into PDF with ConTeXt. Witness the cut out ends of the arrow. How to fix that? Being able to add some margin would be a solution, which may be desirable anyway in some cases. Is that possible?

Not super fan of enclosing each and every of my graphics in a beginfig...endfig statement, but it does the job indeed. Although in my case I must give a number parameter to beginfig, otherwise I get an error. Thanks Sreeram!

[NTG-context] Rendering Standalone MetaPost Graphics with ConTeXt
I’d like to use MetaPost to generate all sorts of standalone graphics (ultimately converted to SVG). For various reasons (among others, MetaFun and advanced text processing) I want to use MetaPost as embedded in ConTeXt rather than a standalone installation. metapost.mp fill fullcircle scaled 10cm; Whether I run context metapost.mp or mtxrun --script metapost metapost.mp I get a PDF document that contains no page. The mtxrun version generates the following temp file: mptopdf-temp.tex \starttext \startMPinclusions fill fullcircle scaled 10cm; \stopMPinclusions \stoptext Looking at the wiki, it seems that \startMPinclusions is not meant to actually render any content, just to include MetaPost code like function definitions. I guess I would have expected \startMPpage instead. Am I doing something wrong, or is that an error in ConTeXt?

Thanks Aditya and Hans! Glad to hear I wasn’t missing anything obvious.

[NTG-context] Reset environment between MetaPost graphics?
Hi, Say I’m writing a document containing many independent MetaPost figures. I don’t want to bother with enclosing each and every graphics in a ‘begingroup...endgroup’ with the appropriate ‘save’ statement. But I don’t want variables from previous graphics to leak into following ones either. Like this: % SOF \starttext Text about some topic. \startMPcode u=1cm; draw (-u, u)--origin--(u ,u); \stopMPcode Now on to another topic. \startMPcode u=2cm; % Triggers an error: Inconsistent equation (off by 28.34645) draw (-u, u)..origin..(u ,u); \stopMPcode \stoptext % EOF Is that achievable?

I am using Evince indeed and I would never have thought of checking with another PDF viewer. All is well on the ConTeXt side, my document displays fine in Firefox.

[NTG-context] Emojis showing up in black instead of colours
Hi there,
freshly upgraded LMTX installation. TwemojiMozilla.ttf downloaded from
GitHub [1].
The following:
\usemodule[fonts-emoji]
\definefontfeature
[overlay]
[default]
[ccmp=yes,
colr=yes,
dist=yes]
\starttext
{\definedfont[name:twemojimozilla*overlay] \ShowEmoji}
\stoptext
gives me pages of emojis, all black. According to what is described on
Stackexchange, I should be getting colours. Am I doing something wrong?
Thanks,
Vincent

The purpose of abbreviations is, well, to abbreviate. Even though ‘ème’
is seen a lot, it’s wrong because it’s too long. Source (pretty
official):
https://www.academie-francaise.fr/abreviations-des-adjectifs-numeraux
So for numbers starting from 3 the proper abbreviation is ‘e’.
For 1 and 2 it’s more complicated, however, as it depends on the
gender. For 1:
* masculine: 1er
* feminine: 1re
In addition for 2, and when the enumeration contains only 2 elements,
there is the option to use the older word ‘second(e)’:
* masculine: 2d
* feminine: 2de
For 3 elements and above, we always use the newer word ‘deuxième’,
which is abbreviated in the form of the generic ‘e’.
While that rule is optional, people who use tools like ConTeXt are
likely to pay attention to that kind of details and will probably want
to use it.
Finally, we have to add an ‘s’ to all the abbreviations if the plural
is needed (the 1st (1ers) elements, the 2nd (2ds or 2es) elements,
etc., vs the 1st (1er) element, 2nd (2d or 2e) element…).
Now, can all those subtleties be coded in a function? :)
