One can use Unicode superscript and subscript numbers, as in ²³⁵₉₂U, which is easier to read.

Re: [NTG-context] Nuclear reactions
Hi List,
I am still interested in knowing if there is a good way to do nuclear reactions
using \chemical. But I found something that works for my current needs:
\define[1]\Sr{\mathord{\rm Sr}__{38}^^{#1}}
\define[1]\Xe{\mathord{\rm Xe}__{54}^^{#1}}
\define[1]\U{\mathord{\rm U}__{92}^^{#1}}
\starttext
Reaction:
\startformula
\U{235} + n \rightarrow \Sr{94} + \Xe{140} + 2n
\stopformula
\stoptext
Since I will be writing many reactions with a dozen or so different atomic
symbols, it makes sense to create a command for each atomic symbol that adds
the correct atomic number and takes the mass number as an argument.
Hope someone else can benefit. I still getting used to ConTeXt's treatment of
{…}, which does not appear to be TeX's way.

[NTG-context] https://wiki.contextgarden.net/Enumerations problem
In https://wiki.contextgarden.net/Enumerations there is this example:
%
\setupwhitespace[big]
\definesymbol[1][$\triangleright$]
\startcolumns
{\bf joinedup:}\par before \startitemize[joinedup]
\item test \item test \stopitemize after \par
{\bf nowhite:} \par before \startitemize[nowhite]
\item test \item test \stopitemize after \par
{\bf joinedup,nowhite:}\par before \startitemize[joinedup,nowhite]
\item test \item test \stopitemize after \column
{\bf joinedup,nowhite,before:} \par before
\startitemize[joinedup,nowhite,before] \item test \item test \stopitemize after
\par
{\bf joinedup,nowhite,after:} \par before
\startitemize[joinedup,nowhite,after] \item test \item test \stopitemize after
\stopcolumns
%
In my test "joinedup" leaves whitespace before the first list item and
after the last, but in the sample output there is no space.
While someone (?) is thinking about that, my (extremely rudimentary!) tests
also indicate that there is no need to use "joinedup" when you use "nowhite".
Is this indeed the case (in which case the wiki page could use an edit) or
are there case where both "joinedup" and "nowhite" are needed together (in
which case the wiki page could stand a little more information).
Thanks.
Jim

[NTG-context] \setupitemize[indentnext=auto] broken?
In the wiki page https://wiki.contextgarden.net/Indentation there is the
following example:
%
\setupindenting[medium,yes]
\setupitemize[indentnext=auto]
\startitemize
\item One
\stopitemize
This paragraph should be indented - due to the blank line after
\type{\stopitemize}.
\startitemize
\item Two
\stopitemize
This paragraph should not be indented.
%
Tragically, the paragraph which claims it should be indented is not, in
both my test and the wiki page itself.
Is this a documentation bug, a ConTeXt bug, or something else yet?
Cheers.
Jim

[NTG-context] Nuclear reactions
Hi list,
I’m writing nuclear reactions. When add prescripts to atomic symbols with two
letters, (Be, Sr, Xe, etc.) the prescripts split the atoms! (See output below.)
\starttext
Text: \lohi[left]{4}{10}Be.
Reaction:
\startformula
{\rm U}^^{235}__{92} + n \rightarrow {\rm Sr}^^{94}__{38} + {\rm
Xe}^^{140}__{54} + 2n
\stopformula
\stoptext
I looked at \chemical and \molecule, but could not find a way to make isotopes
with those. Any ideas?

I have no strategy. I see it as just an offline repository and archive. The luametatex repos sort of resembles what I have on my machine but even then I always use intermediate 'compare before merge' steps that predate git. Git (or svn) is nice for seeing changes but I admit that I never roll-back using git. When I have to integrate something in e.g. luametatex that comes from git I always diff (winmerge) and "manually merge". So much for stragety: not that fancy. The context updates are assembled from a completely different dev structure (think also of temporary files, runtime files for manuals etc that don't belong in something git) and turning that modus operandi into something git would make my way of doing things pretty inefficient, so unless very little changes etc happen i won't change that. All the git magic is maintained by Mojca and occassionally we discuss how to move on (we have some pending install-from-git stuff but that might take a while before being promoted). I'm not really interested in al the additional stuff like chats, pull requests, keeping track of comments in git, all these (for me useless) statistics. I don't want to end up in an endless 'check this or that' noose, so for me email and communicating (could be visual) with some involved does it well; more fun too. For some other projects git(hub|lab) is a communication method, basically an on-line storage. Did you guys ever consider having a cgit interface and hosting it. A bunch of projects have done it heck. Even git, which is where everything solely depends on in the end, is running it. https://git.kernel.org/pub/scm/git/git.git/ https://git.zx2c4.com/cgit/about/ There is not much to gain with adding yet another interface to what we have now. It only works if one or more people commit (no git pun intended) themselves long-term to it which relates to ie beging used. (Keep in mind that it's all volunteer work.)
