Re: [NTG-context] Displayed formula inside paragraph change vertical space before the paragraph

[Jeong Dal]

Dear Mikael,

 I didn’t see any problem which you mentioned when I run it under the ConTeXt 
version 2016.10. 6 MKIV beta.
But I saw a change the vertical space when I run it under ConTeXt version 2016. 
12. 28 MKIV beta after updated the bata.

I tested in several ways and found that the vertical space is narrow only in 
the following case:

Bla bla bla bla bla bla bla bla bla
%
\startformula
k>1000\implies |1/k-0|=1/k<1/1000=0.001.
\stopformula

Bla bla bla bla bla bla bla bla bla

If I remove either “%” or the formula, then the output looks fine.

As Otaired said it is better to open a new thread.

Best regards,

Dalyoung

Hi Mikael,

Thanks for making it clear to me: I was looking for the changes in vertical

2016.05.17 from TeXLive, the issue is not present, as one may see from the 
attached output.

Hi Mikael,

Thanks for making it clear to me: I was looking for the changes in vertical 
spacing around the formula… Now it is clear that there is a bug in the vertical 
spacing: when I typeset your example with mkii or mkiv ConTeXt Version 
2016.05.17 from TeXLive, the issue is not present, as one may see from the

Maybe you should open a new thread with a title like « Bug in vertical spacing

Thank you for testing, Otared.

I still have the same problem with a freshly installed

ConTeXt  ver: 2016.12.28 17:55 MKIV beta  fmt: 2017.1.14  int: english/english

Re: [NTG-context] Displayed formula inside paragraph change vertical space before the paragraph

[Otared Kavian]

Hi Mikael,

I tested your example but I see no difference in the outputs, with, or without 
a blank line between the text and the displayed formula.
I am using ConteXt 2016.12.28 17:55 MKIV beta.

Best regards: OK

Re: [NTG-context] Displayed formula

2007/7/19, Oliver Buerschaper [EMAIL PROTECTED]:
 Hi folks,

 I desperately need your help ... why does the following code not
 produce my formula?

 \starttext
 \startformula

\startformula\relax

or

\startformula[]

 [-iH(A),-iH(B)]=-iH([A,B])
 \stopformula
 \stoptext

 I have a feeling that ConTeXt interprets the first part of my formula
 as an argument to \startformula ...

you're right

 Thanks for your help,

I don't know what ConTeXt is doing behind the scenes, but I found two

 Wolfgang, Jelle,

 thanks for your suggestions ... problem solved!

This thread brings up something that I have been thinking of for a 
while. Similar problems occur in amsmath aligned family which accepts 
an optional argument. mathtools.sty has an option so that the optional 
argument will work only if placed on the same line. In terms of ConTeXt 
that means,

\startformula[9pt]
math
\stopformula

\startformula [9pt]
math
\stopformula

will put the formula in 9pt font, while
\startformula
  [9pt]
  math
\stopformula

will display [9pt] math. I have not looked into the details of how 
mathtools implements this, but it should be possible to port it to 
context. Will something like this be useful to have, or is adding 
\relax once in a while alright?

I guess it'll depend on how hard this is to implement. At the moment  
I'm dealing with lots of Lie brackets so I'd certainly appreciate  
this feature very much ... in my opinion it would also improve  
consistency: the same markup works for any kind of formula!

On the other hand one could also enforce the use of \[ whenever the  
glyph [ should be actually typeset. This would be the other road to  
consistency ;-)

At first I thought I'd need to include \hangindent and
\hangafter to use it, but then I realized that you were using those
comands for simulating the figure inclusion.

I put your patch at the start of my test file using the dummy figure,
and it works great.  Thanks!  I'll keep using it and let you know if I
notice any side effects, but hopefully it can go into the
distribution.

 In the following small example, two squares are cut out of the long

 no problem with that.  But the second removed square is after the

 If I make add a \placeformula before the \startformula, then the
 equation number goes where it should (below the right edge of the
 figure), but the area below it is still whitespace.
 
 Is it a bug or is there an option to make startformula not interfere
 with the paragraph shape calculation?
