I have noticed before what you described. If there are 8 items, the outputs are 
all different depends on the location of \overline.
I couldn’t see any pattern in the output.
The only thing I can see is that the command ‘\overline’  makes a blank line,
and I just guess that it is related with the column environment.

Yes, it is also my hope. And, I believe that he also solve the alignment 
problem too.

Best regards,

Dalyoung

Hi Wolfgang,

Thanks for your help. In math-ali.mkiv there are the following lines:

\setupmathmatrix
[\c!distance=\emwidth,
\c!left=,
\c!right=,
\c!align=\v!middle]

Is it here where one has to change something? I confess that I am not 
at all familiar with the source code…


No, this is only the default setup for matrices. The alignment is done 
at the begin and end of the cell content (look at the commented commands 
below):


\unexpanded\def\math_matrix_start_cell
  {\dostarttagged\t!mathtablecell\empty
   \hss
  %\math_left_of_equalign
   \startimath
   \math_matrix_set_style
   \tabskip\zeropoint
   \everycr\emptytoks}

\unexpanded\def\math_matrix_stop_cell
  {\stopimath
  %\math_right_of_eqalign
   \hss
   \dostoptagged}

Re: [NTG-context] Problem with math alignment

[Otared Kavian]

Dear Dalyoung,

Thank you for having tested my example.

Regarding what you are reporting in another thread about the weird behaviour of 
\overline in columns, I was traveling and could not test your file. Now I 
tested your example and I get the same result as you with the latest beta 
2017.11.08 22:45.
The strange fact is that if one puts 
\startitem $\overline{A} = A$ \stopitem
as the first item in your example (instead of the second), then ConTeXt creates 
three columns, with the first item the result of the above line, and then items 
2 and 3 in the second column and finally item 4 in the third column. Despite 
this the textwidth is divided into four…

I hope Hans will see your message and fix the issue.

Best regards: OK

Hi everybody,

Does anyone have noticed that the mathalignment has changed its 
behaviour recently? I think a bug has managed to enter the environment 
which handles the mathalignment, at least since a few weeks ago. I did 
not report it earlier because I was traveling and did not have a 
stable internet access.
The align option for mathmatrix doesn’t work anymore because the 
function is disabled (commented) in the code.

Re: [NTG-context] Problem with math alignment

[Jeong Dal]

Dear Otared,

I run your code and found that they are not aligned properly as you want.
But I don’t know how to do for the correct alignment.

Did you see the mail about the \overline problem in column environment which I 
listed recently?
It is a different problem from yours, but I’d like to know whether  you got the 
same output as mine or not.
Would you please check it in your computer?

Thank you.

Dalyoung

Re: [NTG-context] Problem with math alignment

[Otared Kavian]

Hi Matthias,

Thanks for your answer. I think that Hans has changed the way entries of 
mathmatrix are handled, that is they are now centered and this cannot be 
changed…
However I think now that my way of using mathmatrix in order to get aligned 
cases, should be changed into the following:

\definemathalignment[alignedcases]
[n=3,
align={right,left,left},
distance=3pt,
left={\left\{},
right={\right.},
style=\displaystyle]

Once this is done, the result is as expected since the math alignment 
environment accepts changing the alignment in each column. However the big 
problem is that one loses the left brace encompassing the displayed equations… 

I hope Hans will read this and help fix the issue…

Best regards: OK

Re: [NTG-context] Problem with math alignment

[Weber, Matthias]

Same here. Curiously, the Garden version is ok, while the newest beta seems to 
make all alignments centered.


Minimal  Example:


\starttext
\startformula
A=\startmathmatrix[align={right,right}]
\NC1\NC-1\NR
\NC-1\NC1\NR
\stopmathmatrix
\stopformula
\stoptext

[NTG-context] Problem with math alignment

columns are centered…)

in fact, this minimal example works for me too. BUT adding those three

compilation fail. no idea what's happening here. I will now try to reduce  
my original document to a hopefully minimal example triggering the  
described behaviour.


any hints, where to look regarding possible reasons of the observed  
behavior would of course be appreciated.

0.63 what? luatex? then you need to check things as we're beyond 1.00 now


I was refering to the `context --version' output:

resolvers   | trees | analyzing 'home:texmf'
mtx-context | ConTeXt Process Management 0.63
mtx-context |
mtx-context | main context file:
path_to/context/tex/texmf-context/tex/context/base/mkiv/context.mkiv
mtx-context | current version: 2017.01.17 17:37

I _was_ under the impression that this is current since I did an update
and `current version' gives a date from last week. or that's what I
believed would happen, when re-running `first-setup.sh': am I mistaken?
if this is a stupid question I'd accept a RTFM answer ;-).


the context version is: 2017.01.17 17:37

(best also mention the reported luatex version in such cases)

the 0.63 hardly changes as mtx-context hardly changes





two observations:

1.
in a new document including assorted equations everything went fine
until I tried something like

\startformula
x = \left 1 + 2 \right
\stopformula


\left( ... \right)

left and right take an argument that has to be some known open or
close operator


yes, I know. sorry for the glitch. I _meant_

\startformula
  x =  \left ( 1 + 2 \right )
 \stopformula

and _that_ is what's still causes the `Undefined control sequence'
(both, in the new as well as the two year old unmodified document) --
actually it is thus reported in
the error message (in the previous mail, too):

"l.472 x = \left (
1 + 2 \right )"



this just works here ... so can others confirm it?

\starttext

\startformula
x =  \left ( 1 + 2 \right )
\stopformula

\stoptext



which caused an error:

8<--
 ! Undefined control sequence


\strc_synonyms_insert_meaning ...urrentsynonymtag
  {#2}\fastsetup
{\??simplel...
\math_left ...ame \??mathleft \meaning \nexttoken
  \endcsname
\expandafter \l...
l.472 x = \left (
1 + 2 \right )
8<--

2.
an old document (not modified these 2 years) does no longer compile due
to apparently the same problem (not understanding `\left', `\right'.

question: my understanding is, that `context' supports "everything" out
of the box (notably equations) and there is no need for explicit loading
of additional packages? so `\left' etc. _should be defined (and it
_used_ to work 2 years ago)? what am I missing?

thx, joerg

[NTG-context] Problem with math!

[Verhaag, G.C.H.M.]

Hi ConTeXt users,

Currently I'm experiencing problems with inline math mode in combination 
with the addff{oldstyle} command!


The attached test file doens't compile with the latest version 2012.2.18 
(MkIV), which seems to be caused by the introduction of the $\bullet$!


With older versions this worked okay!

Regards,
Gerard Verhaag
\language[nl]

\usetypescript[schola]
\setupbodyfont[schola,10pt]

\definefontfeature [oldstyle] [latn] [onum=yes]

% adding this feature set
\addff{oldstyle}

\starttext
 Math symbols like $\bullet$ NOT working any more from version 2012.2.18!
\stoptext

Re: [NTG-context] problem with math and TeXgyre and MKIV

[Alan BRASLAU]

Does anyone use math?  For I am surprised that nobody is complaining.
(recent minimals, since 8 June, mkiv)

The following minimal example

% mkiv
\usetypescript[postscript]
\usetypescript[pagella]

\starttext
default: $A = \pi r^2$

\switchtobodyfont[postscript]
postscript: $A = \pi r^2$

\switchtobodyfont[pagella]
pagella: $A = \pi r^2$
\stoptext

renders incorrectly.
1. no TeXGyre \pi (or other math symbols)
2. the math r is strange (outlined and unselectable under Acroread)
3. numerous error messages using libpoppler (okular, evince)

I have confirmed the buggy behaviour offline, but I'm afraid that only
Hans can fix it.

(my off-list response:)
 The version that breaks is apparently beta-2009.06.10 (the version
 from 8th June still worked). But there are too many changes to find a
 single simple reason for the failure. I leave it to Hans to sort it
 out ... now that he has the git repository, it should be easier for
 him to find the reason :) :) :)

either patch supp-lan:

interesting how long it takes for such a bug to show up

I have the following problem:

I always get 3 pages, but I want to have two: The recto with Hi and its

Good idea, I only remembered \mid which is something like '\,|\,'.
(I need to find my texbook, someone seems to have borrowed it.)

 PS: Did you get any answer for this one of your previous question :
[startbodymatter + alternative=doublesided gives odd number of pages]

No, unfortunally not.

So do I ;-)
