Re: [NTG-context] Size of the last shipped page by Lua?

Helo,

thanks both for proposals - I really need just to READ the values (and not to 
modify them).

Best regards,

is my usage of these in shipouts « after » callback).

If these are not reliable, what’s the reliable way to get the page width
and height ?


\starttext

Re: [NTG-context] Vertical padding in tables

2016-09-11 Thread Jose Luis Arellano

Hi Wolfgang,

Thanks for the answer, the strut option was the trick.

What am trying to do is create a table without frames in body and set
the distance between text in cells to match the distance defined in
\setupinterlinespace.
How can i do that?

Thanks.

[NTG-context] Math letters in commands

2016-09-11 Thread Hans Åberg

Just found that the code below does not work as intended, because \𝐝𝐢𝐦 will be 
parsed as \𝐝 followed by 𝐢𝐦. Can’t tell if it ought to be changed, though one 
could think other cases where it might be natural. The command definition of \𝐝 
works though.


\setupbodyfont[xits,10pt]

\setupmathematics[lcgreek=normal, default=normal]

\definemathcommand[𝐝𝐢𝐦][nolop]{\mfunction{𝐝𝐢𝐦}}
\definemathcommand[𝐝][nolop]{\mfunction{𝐝𝐢𝐦}}

\starttext

Note that $\𝐝𝐢𝐦 𝑉 = 𝖫$, although $\dim 𝑉 = 4$.

Dear list.

How can I control vertical padding in natural tables?
You can use offset the control the padding on all four sides and loffset 
etc. for the individual sides.


\startTEXpage[offset=1cm]

\bTABLE[offset=1mm,strut=no,style={\switchtobodyfont[tt,40pt]}]
\bTR
\bTD[loffset=1cm,toffset=1cm]

Hi Mingranina,

Indeed, as of today, ConTeXt version 2016.09.09 08:21 MKIV beta, there is a 
small bug with the location of equation numbers when one chooses
\setupformulas[location=left]
and Hans is aware of the problem, which will be solved (he is rebuilding some 
fundamental fetaures in displayed math formulas).

Meanwhile, if you typeset your document with a version such as the one from

ConTeXt  ver: 2016.05.17 19:20 MKIV current

Dear Aditya, Otared, and Hans,
 Hello,

 Thank you all very much for your help. Your codes work fine. However when I use
 \setupformulas[location=right] the equation numbers apperar on the rightmost of
 the line, but with \setupformulas[location=left] the equation numbers
appear near
 the formulas and not on leftmost of the line. What should I do so
that in both cases
 the equation numbers appear near the formulas or with
\setupformulas[location=left]
 the equation numbers appear on the leftmost of the line?

Hi Mingranina,

For displayed aligned formulas it is better to use \startalign…\stopalign,

Please have a look at the following:

Best regards: OK
%%% begin align-equations.tex
\starttext

\placeformula
\startformula
\startalign
\NC c^2 \NC= a^2 + b^2  \NR[+] 
\NC a^2 + b^2 \NC = c^2  \NR[+]

Hi Hans,

Following up the previous bug report, I tried the latest version,
ConTeXt  ver: 2016.09.09 08:21 MKIV beta, and noticed that you have
solved one part of the problem with the placement of equation numbers
on the left, when using \startalign.
Actually the location of those equation numbers is correct as far as
the horizontal distance is concerned, but it is not vertically.
In the attached PDF (which is the result of the following example) one
can see that equation number (5) is placed on the grid line 10, while
it shoul dbe placed on line 11 in alignment with the corresponding
formula. Moreover equation number (4) does not show up at all (that
number should be placed a little bit below line 9 of the grid).


I think that we need to create a test suite for math alignment. The
sources for my old article on math alignment could be the initial source
of examples.


fyi: one reason for 'issues' is that i try to simply these alignment 
mechanisms so that they can be controlled better for use in framed and 
such (local vs page stream usage) and spacing and so .. we'll get there 
eventually
