Hi Mikael,

Thank you for your reply. When I typeset the example you sent me, that is

%begin 240117-1-bis.tex

\definemathsimplealign[alignedcases]
		[left={\startmathfenced[cases]},
		right=\stopmathfenced,
		align={1:right,2:left,3:left},
		strut=yes]

\setupformula
  [location=left]

\starttext

\samplefile{knuthmath}

\startplaceformula
	\startformula
		\startalignedcases
			\NC u'(t) - \nabla \cdot (a(x)\nabla u) + Vu \NC = 0      \NC \mtext{bla bla bla}     \NR
			\NC u(x,0)                                   \NC = u_0(x) \NC \mtext{bla bla}         \NR
      \NC u(t,\sigma)                              \NC = 0      \NC \mtext{bla bla bla bla} \NR
		\stopalignedcases
	\stopformula
\stopplaceformula

\samplefile{knuthmath}

\startplaceformula
	\startformula
		\startalign[location=packed,n=2,m=2,align={1:right,2:left},fences=cases]
			\NC u'(t) - \nabla \cdot (a(x)\nabla u) + Vu \NC = 0      \NC \NC \mtext{bla bla bla}     \NR
			\NC u(x,0)                                   \NC = u_0(x) \NC \NC \mtext{bla bla}         \NR
      \NC u(t,\sigma)                              \NC = 0      \NC \NC \mtext{bla bla bla bla} \NR
		\stopalign
	\stopformula
\stopplaceformula

\samplefile{knuthmath}

\stoptext
% end 240117-1-bis.tex

I get something different than the PDF you sent me: the formulas run into the text just above them, as you can see in the attached PDF. I am using ConTeXt LMTX version 2024.01.08 on MacOS 11.7.10. I don’t see what is wrong with my installation…

Best regards: Otared

Hi Mikael,

I installed anew the latest version and I get still the same bizarre result with math alignment.

Please can someone on the list typeset the following in order to see whether the result is correct or not ?

%begin 240117-1-bis.tex

\definemathsimplealign[alignedcases]
		[left={\startmathfenced[cases]},
		right=\stopmathfenced,
		align={1:right,2:left,3:left},
		strut=yes]

\setupformula
  [location=left]

\starttext

\samplefile{knuthmath}

\startplaceformula
	\startformula
		\startalignedcases
			\NC u'(t) - \nabla \cdot (a(x)\nabla u) + Vu \NC = 0      \NC \mtext{bla bla bla}     \NR
			\NC u(x,0)                                   \NC = u_0(x) \NC \mtext{bla bla}         \NR
      \NC u(t,\sigma)                              \NC = 0      \NC \mtext{bla bla bla bla} \NR
		\stopalignedcases

      \NC u(t,\sigma)                              \NC = 0      \NC \NC \mtext{bla bla bla bla} \NR

Thanks in advance: Otared

[NTG-context] Re: Math alignment issue

[Jeong Dal via ntg-context]

Dear Otared,

I got the same output in which there is an overlap of the formula on the last line of the paragraph.  The following line shows the version of my installation.

system          > 
system          > ConTeXt  ver: 2024.01.08 11:23 LMTX  fmt: 2024.1.17  int: english/english

Best wishes,

Dalyoung

Dear Dalyoung,

Thank you for testing, which shows that there is a bug somewhere.
Mikael who follows the math stuff is aware of the problem, and I guess Hans will be informed.

Best wishes for 2024: Otared

Since it is working locally here, It will likely be fixed
automatically with the next upload.

Hi Mikael,

Thank you so much for your attention and help.
Is there a way to get a working version before Hans does a new upload? Or even a temporary patch?
This is because I have to prepare a presentation for next Monday and I have to use extensively math align…

Best regards: Otared

Dear Hans,

Thanks for the new upload.
It clears the issue of the math alignment.

Thanks again.
