Hi there,
I noticed that Math align is not working properly. In particular I mean the alignment. For example, the following code
\starttext
\startformula \startalign[m=2,distance=8em,n=5, align={right,middle,middle,middle,left}] \NC 0 \NC < \NC 2x + 5y \NC < \NC 10 \NC 4 \NC < \NC 3x + y \NC < \NC 9 \NR \NC 3 \NC < \NC 2y + 3z \NC < \NC 15 \NC 10\NC < \NC 8y + 5z \NC < \NC 20 \NR \stopalign \stopformula
\stoptext
is copied from https://dl.contextgarden.net/myway/mathalign.pdf but doesn't produce the intended result.
What's wrong?
Best regards, Johann
Hi Johann,
The example you sent works fine here with LMTX version 2020.12.28 01:41. Which version of ConTeXt are you using ?

Hi Otared,
I'm using the same version. The problem is the "right"-alignment. See the 4 on the right side. It should be right-aligned. I attached my pdf.

Hi Alain,
I don't know what you mean by "you have two position in the second and one in the first" ?
The 4 is not aligned correctly. Please see https://dl.contextgarden.net/myway/mathalign.pdf where the example comes from. The output looks different.

One has to indicate the align pattern for all columns, otherwise it defaults to left, it seems:

Okay, but I think it's a bug, because as you see in the linked pdf it worked the simple way some years ago...

The developers might tune in; perhaps it was changed.

Yes, something has changed internally. Earlier, if you used:
\startalign[align={right,left}, n=4] ... \stopalign
then the alignment was right left right left, i.e., the alignment cycled. Now, the alignment is right left left left, i.e., unspecified alignments default to left. So, in your example, each column in the second "block" is left aligned. To change that, you can use:
\starttext
\startformula \startalign[m=2,distance=8em,n=5, align={right,middle,middle,middle,left, right,middle,middle,middle,left}] \NC 0 \NC < \NC 2x + 5y \NC < \NC 10 \NC 4 \NC < \NC 3x + y \NC < \NC 9 \NR \NC 3 \NC < \NC 2y + 3z \NC < \NC 15 \NC 10\NC < \NC 8y + 5z \NC < \NC 20 \NR \stopalign \stopformula
\stoptext
But this is ugly.
I haven't looked at the math alignment code in a while, but I'll check with Hans if the old behavior can be reintroduced.

This works nicely. Thanks.
I'll also go back to the mathalign document and try to update it for the current LMTX to catch other regressions which might have happened.

Hi Aditya,
thank you very much, now I need to specify the alignment only for one "column" and it gets applied for all of them. However, there is still the problem with the standard setting of the alignment. For example,
\starttext \startformula \startalign[m=2, align={right,left}] \NC ab \NC = cd \NC efgh \NC = ijkl \NR \NC efgh \NC = ijkl \NC ab \NC = cd \NR \stopalign \stopformula \stoptext
works now. But the setting [align={right,left}] should be the standard when n is not set. So (also according to your documentation) the following code
\starttext \startformula \startalign[m=2] \NC ab \NC = cd \NC efgh \NC = ijkl \NR \NC efgh \NC = ijkl \NC ab \NC = cd \NR \stopalign \stopformula \stoptext
should work, but it doesn't. The first column is right-oriented, the third (i.e. the first in the right "column") not.
Could you please fix that?
Thanks you very much, Johann
