Re: [NTG-context] Bug in placeformula
Hi Mikael, Thank you for your reply. For the time being I am not in a hurry to solve the issue with placeformula (when the numbers are on the right, there is no problem…).

We must have missed this one while testing. It should be fixed. If you for the moment can live without splitting, then this seems to give you the formula number where expected: \placeformula \startformula[location=left,split=no,numberlocation=overlay] a^2 + b^2 = c^2. \stopformula (or put the keys in \setupformula) I hope it helps. /Mikael ___ 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 ___
[NTG-context] Bug in placeformula
Dear Hans, dear Mikael, In my experiments with the new math engine, I noticed that there is an issue with \placeformula when one sets the location of the numbers on the left: the number is one line above the formula. Here is a minimal example: % begin bug-placeformula-left.tex \setupformulas[location=left] \starttext \placeformula \startformula a^2 + b^2 = c^2. \stopformula \stoptext % end bug-placeformula-left.tex Moreover, in some environments (such as enumerations) the bug destroys completely the flow of text but I could not set up a minimal example to send you.

Re: [NTG-context] Bug in \placeformula
Hi Henri,
Your are right there is an issue with \startmathcases…\stopmathcases: the
equations are not numbered when using this structure.
As a temporary solution you can use \startmatrix…\stopmatrix as in the
following, or you can define your own \startalignedcases.
\starttext
\placeformula
\startformula
f(\mu,t) :=
\startmatrix[left={\left\{\,},right={\right.}]
\NC 0 \NC \mu > 2t \NR
\NC \pi/2 \NC \mu = 2t \NR
\NC \pi \NC \mu < 2t \NR
\stopmatrix
\stopformula
\stoptext
Best regards: OK

Re: [NTG-context] Bug in placeformula with framed text
Hi Hans,
Thanks a lot for having fixed the issue I was reporting.
Unfortunately I found another issue related to placeformula and alignment in
math mode.
In the following example the use of \startalign in a \placeformula triggers a
weird behavior in the sense that the following instance of \startformula gets
also a number, even though one does not issue a \placeformula command. Moreover
the number is placed incorrectly.
In the resulting PDF I am attaching, please look at the numbers (4) and (8)
placed incorrectly (and they are not wanted neither…).
When one removes the \placeformula command, the result is correct.

[NTG-context] Bug in placeformula with framed text
Hi Hans,
It seems that there is a bug in the latest beta (ConTeXt vesion: 2016.07.01
16:28) when using \placeformula with a framed text environment. The numbers for
the formulas are placed incorrectly, on the left as well as on the right.
Also, as one may see in the example below the numbering of the formulas begins
at 2 instead of 1 at the first instance, and at it continues at 6 instead of 4
in the second instance.
Below is an example (sorry if it is not absolutely minimal: I ran into this bug
when updating a lecture notes which uses a left frame around \proclaim stuff).
I attach the PDF showing the problem. I wonder whether this is related to the
new features introduced recently for math frames.
The code gives correct result with ConTeXt version 2015.05.18 12:26 from
TeXLive 2015).
