Hi!
I asked about this before, and it is a feature.
It can be switched off with
\setupmathematics[
collapsing=1,
]
Hope it helps!
Indeed. Aditya is in charge of decisions about these defaults so if
you want it differently you need to convince him. (I'm not sure how
many users depend on it.)
We can turn it off by default. But it might be better to have a more
versbose interface:
\setupmathematics[collapsing=yes|no]
with the default value being collapsing=no.
we already have "none" and th enumbers represent:
1 specials
2 specials + mathlist
3 mathlist + specials
Now that Alan is entering his math in unicode symbols we can default to
'none'.

Re: [NTG-context] Strange behavior in math mode: < and minus sign give leftarrow
Thanks Hans for your attention! The problem of such an usual default is also with newcomers who would not know about this feature in ConTeXt: when one writes maths one would not guess that typing an inequality like $n < -1$ would end up in $n \leftarrow 1$. And writing such inequalities is very common… while \leftarrow is used seldom in a mathematical text. So I think having the default collapsing=1 would be more logical, and more in line with the spirit of TeX. I hope Aditya will be convinced… Best regards: OK > On 10 Apr 2019, at 09:53, Hans Hagen wrote: > > On 4/10/2019 9:40 AM, Mikael P.

Hi Mikael, Thanks for your quick reply. Indeed I did not know about this feature, and setting collapsing=1 solves my problem… Best regards: OK > On 10 Apr 2019, at 09:40, Mikael P.

[NTG-context] Strange behavior in math mode: < and minus sign give leftarrow
Hi Hans,
While testing old documents with lmtx, I noticed that with recent versions of
mkiv, as well as LuaMetaTeX, there is a strange behavior in math mode: when the
characters < and - follow each other one gets \leftarrow… This is embarrassing
when one writes inequalities for negative numbers.
So one has to separate them in order to obtain with curly braces. Can this be
fixed or is it intended ?
