[-- Attachment #1.1.1: Type: text/plain, Size: 717 bytes --]

Hi,

I currently have the case of a strange extra space in math mode when using cases in inner align.

Here is a MWE to demonstrate the problem:
```
\definemathsimplealign[inneralign]
\startdocument
\startformula
	\startalign
		\NC a = b \NR
		\NC \NC \startinneralign[n=3,align={1:right,2:middle,3:left}]
			\NC A \NC = \NC B \NR
			\NC f(x,y) \NC = \NC \startcases
				 \NC \text{strange}  \NC a \NR
				 \NC \text{normal}  \NC b \NR
				 \NC \text{also normal}  \NC b \NR
			\stopcases
		\stopinneralign
	\stopalign
\stopformula
\stopdocument
```

"strange" and "normal" are not aligned what I would expect but strange has more space in front of it.
Is this a usage error or a bug in the math engine?

Best,
Gerion

Hi,

There is indeed a space added in this case. But you do not need n=3.
And in fact, you do not need a simplealign either, but can use an
ordinary align, with location=packed. It looks like you had the wrong
number of \NC. I hope the examples below help, the last one is merely
for Hans for looking into why the relation-digit space is added there.

/Mikael

\definemathsimplealign[inneralign]

\showglyphs
\showboxes

\showmakeup[mathglue]

\startdocument

OK with \typ {n=2} instead of \typ {n=3}:

\startformula
  \startalign
    \NC a = b \NC \NR
    \NC       \NC \startinneralign[n=2,align={1:right,2:left}]
                    \NC A      \NC = B \NR
                    \NC f(x,y) \NC = \startcases
                                       \NC 1 \NC a \NR
                                       \NC 1 \NC b \NR
                                       \NC 1 \NC b \NR
                                     \stopcases
                                       \NR
                  \stopinneralign
                  \NR
  \stopalign
\stopformula

With align and location set to packed, instead of simplealign

\startformula
  \startalign
    \NC a = b \NC \NR
    \NC       \NC \startalign[n=2,location=packed,align={1:right,2:left}]
                    \NC A      \NC = B \NR
                    \NC f(x,y) \NC = \startcases
                                       \NC 1 \NC a \NR
                                       \NC 1 \NC b \NR
                                       \NC 1 \NC b \NR
                                     \stopcases
                                       \NR
                  \stopalign
                  \NR
  \stopalign
\stopformula

Extra \typ {reldig} space before the 1:

\startformula
\startalign[n=3,location=packed,align={1:right,2:middle,2:left}]
                    \NC A      \NC = \NC B \NR
                    \NC f(x,y) \NC = \NC \startcases
                                           \NC 1 \NC a \NR
                                           \NC 2 \NC b \NR
                                         \stopcases
                                           \NR
\stopalign
\stopformula

\stopdocument

Hi Mikael,

your examples are simpler, that is correct, but all of them have the extra space.
Thanks for the simpler code, I will integrate it!

Hi Gerion,

Hans is working on the problem.
