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. Best regards, Johann On Tue, 2020-12-29 at 21:37 +0100, Otared Kavian wrote:

Hi Johann,

The example you sent works fine here with LMTX version 2020.12.28 01:41. Which version of ConTeXt are you using ?

Best regards: Otared

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 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. Best regards, Johann On Wed, 2020-12-30 at 11:26 +0100, Alain Delmotte wrote:

Hi Johann, The 4 is right aligned, but for this column you have two position in the second and one in the first. You could try ~4 and it will align with 10. Best regards, Alain Le 29/12/2020 à 22:27, Johann Birnick a écrit : Hi Otared,

Okay, but I think it's a bug, because as you see in the linked pdf it worked the simple way some years ago... On Wed, 2020-12-30 at 14:38 +0100, Hans Åberg wrote:

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

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. Aditya

Aditya:

can you check this?

I added:

\etoksapp\scratchtoks{\global\c_math_eqalign_column\zerocount}%

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. Aditya
