[NTG-context] Re: How can I use a variable for a MetaPost coordinate ?
Yes, indeed. The metafun manual also explains things about overlays and layers
I hadn't known. I'd previously ignored that manual.
Thank you,

Hi,
I would like to obtain, if possible, a gray gradient like in the image.
My code uses Metapost but maybe this is possible with Metafun.
Have a look into the Metafun manual, chapter 8.1 “shading”.

No, sorry, never tried. I’m only concerned with PDF/X, and even that I

[NTG-context] workaround for wrapping SHA512
Dear list,
I have just added another workaround to long hashes (such as SHA512).
It interleaves colons every two chars:
https://wiki.contextgarden.net/Wrapping#Another_workaround_interleaving_colons.
This makes a longer output, but it is more readable too.
Just in case it helps anyone (who previously discussed this in this
mailing list),

Thank you.
It seems like database solutions like BibTeX & Cie are generally not
suitable for quoting books as they were published – and that’s important
in the contexts of “my” authors (literary studies, history).
For my ConTeXt book, I thought it would make sense, and I would jump
through some hoops just to use the system, but
– most sources that I want to list are never quoted (method=dataset)
– I would need to define my own rendering, e.g. don’t like the handling
of names
– I need additional fields (custom rendering again)
– if I refer to sources, I want a URL or file path in a footnote (custom
cite wrapper macro)
This all works fine without the btx subsysten (I just need to find
solutions for some edge cases, or avoid them), so I probably had wrong
ideas about bibliographies (at least in TeX).
OTOH, for my novel I can use the bib database approach for an extended
person register; the required rendering is much less involved.

[NTG-context] Re: How can I use a variable for a MetaPost coordinate ?
Have a look at chapter 6.4 of the metafun manual. You need StartPage ...
StopPage in your MPcode, then you can knock yourself out by using
variables such as PaperHeight or TextHeight and do all sorts of
calculations.
All best
