Or what am I missing here? I'm not too sure what you're asking here, but Notepad was somewhat- recently updated to handle both CRLF and LF line endings: https://devblogs.microsoft.com/commandline/extended-eol-in-notepad/ But I do agree that the line ending handling seems a little odd. I find it surprising that the buffers internally use CR line endings since no systems in the past 20 years use that. Also, you should probably check to make sure that the results of the file don't depend on the current code page on Windows. Try writing out a buffer from ConTeXt with the following contents: АБВГДЕЖЗИЙКЛМНОПРСТУФХЦЧШЩЪЫЬЭЮЯабвгдежзийклмнопрстуфхцчшщъыьэюя First, run "chcp 65001" before running "context" and record the size of the file written. Then, run "chcp 1251" and run "context" again. Hopefully the file size doesn't change; but if it does, then that means that the binary content of any file written will depend on the system's default code page, which would complicate making reproducible hashes. -- Max ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___

Hi again Max,
this seems to solve the issue in Windows too:
\startbuffer[test]
just a test
and another one
\stopbuffer
\starttext
\startluacode
require("util-sha")
function sha256(str)
if os.name == "windows" then
return utilities.sha2.hash256(str:gsub("\r", "\r\n"))
else
return utilities.sha2.hash256(str:gsub("\r", "\n"))
end
end
\stopluacode
\def\shabuffer#1%
{\cldcontext{sha256(buffers.raw("#1"))}}
\def\shafile#1%
{\cldcontext{utilities.sha2.hash256(io.loaddata("#1"))}}
\shabuffer{test}
\savebuffer[test][temporary-αβγ, prefix=no]
\shafile{temporary-αβγ}
\stoptext
But now I don’t understand is the following issue: if the saved file
contains "\r\n", why does basic Notepad the new lines?
"\r\n" are the chars to get new lines in Windows. Or what am I missing here?
Many thanks for your help,
Pablo

The issue may be trickier than we thought (since fixing Firefox with Heros+LMTX is only part of the issue). Just as a personal note, I tend to avoid using Heros with LMTX, since resulting PDF documents may be displayed (poorly on screen) with Acrobat. I wonder whether this is related to common code for both Acrobat and Firefox (originally comming from https://lists.nongnu.org/archive/html/freetype-devel/2013-05/msg0.html).

I too would prefer less space around the times e.g. \starttext 3.00×10\high{8}
\stoptext is fine (except for the 8 which is nicer in \unit).

Hi Hans,
I also just noticed that the space between the number and the unit is missing
when I typeset with ConTeXt ver: 2022.09.11 20:44 LMTX fmt: 2022.9.25. This
space was present in with the ConTeXt version I was using earlier, from a

[NTG-context] Spacing in \unit
Hello list,
I have a few questions about space produced by the unit command. Consider this
MWE
\starttext
\unit{3.00e8 kg m/s}
$\unit{3.00e8 kg m/s}$
\stoptext
The dot between “kg” and “m” has different spacing depending on whether the
\unit command is in text or math mode. I think that the tighter spacing in the
first one, in text, is correct.
I personally would also like less space around the \times. To me, the number
3.00e8 should be typeset more like a single number, rather than like a product
of 3.00 and 10^8. I am probably in the minority here. If \unit and \digit had
an option for tighter spacing around the \times, I’d use it, but the current
output with more space is probably what most people expect and want. Perhaps
something like [scispace=tight].
Finally, \unit does not play nicely with surrounding spaces. For example:
$2\pi\,\unit{3.00e8 kg m/s}$
causes a fatal error:
tex error > tex error on line 9 in file ./Untitled.tex: Incompatible glue
units (case 1)
\phys_units_direct
#1->\begingroup \the \everyunits \ifdim \lastskip
>\zeropoint \settrue \c_phys_units_dospace \removelastskip \fi
\c_phys_digits_method \unitparameter \c!method \relax \ifmmode \else
\dontleavehmode \fi \edef \currentunit {#1}\always\edef \unitlanguag
$2\pi\,\unit
{3.00e8 kg m/s}$
Using \thinspace produces the same fatal error.
Putting the 2\pi after the \unit{…} can also cause surprises.
$\unit{3.00e8 kg m/s}\times 2\pi$
produces a \times that is right up against the “s”.
I am very happy with all of the work done on spacing in math. I hope that my
observations above are helpful in fine-tuning the excellent system.
Thanks!

[NTG-context] Is there an "align with item on facing page" option?
Is there a way to align text with an item on the facing page? I'm typesetting author biographies for a book and I'm doing two per page. The author's name appears on a line of its own in \tfa size and then the bio text follows. Ideally I'd like their names aligned so that all four (on a two page spread) appear nicely symmetrical. Currently I'm using \godown[\dimexpr80mm-\pagetotal] (for A5 pages) between each pair which works nicely in that if the first biography is too long it overlaps and I know to edit it to be shorter. However, if the second biography is a little long, it pushes the first back up the page a little - maybe only one line - and then it no longer aligns with the the one on the facing page. If I could somehow tell ConTeXt to vertically align the author names then that might do the job? I've tried using two frames above each other with fixed min and maxheight but then I can't get the author's thumbnail picture to place properly and have the text wrap around it.

Hi there,
I reply this question myself: "step" is a key in "\setuptyping"
("\setuplinenumbering[typing]" won’t work here).
Other options for line numbering are configured with
"\setuplinenumbering[typing]".
Just in case it might help for future reference,
