[NTG-context] Incorrect math kerning

2016-05-29 Thread Aditya Mahajan 

Hi,

This is based on a question about latex on tex.stackexchange:
http://tex.stackexchange.com/q/312098/323

but context shows the same behaviour.

The subscript "i" in the following example is kerned incorrectly (it is 
too far away from W). Is this a bug in the font, or with the fontloader?


\setupbodyfont[cambria]

\starttext

\startTEXpage[offset=2mm]
$W_i^i$
\stopTEXpage

\stoptext

Thanks,
Aditya

Re: [NTG-context] Allow for hyphenation in 'firstline' ConTeXt feature ?

2016-05-29 Thread josephcanedo 
Yes, I probably should have written ‘Would it be time consuming etc… ?’ :-)

In any case, I had a try to the test file, and it works very well.


Thanks for your very swift reply.


Best regards

depends on what one finds 'difficult' ... by now i can probably do most 
i want at that level in which difficult is replace by 'just takes time'; 
also, one needs to keep in mind that trickery like this also needs to 
cooperate with other mechanisms

i'll send you a file to test (no beta as i'm cleaning up some display math)

OK. Perhaps a \NM … command call $…$, then.

The output on the \digits page is wrong, too. (Because of the confusion of “,” 
and “.” in numbers, an international standard suggests to use either of them as 
a decimal separator, and a single space between digits if so wished. Haven’t 
caught on much, though.)

Re: [NTG-context] Tabulate \NN not working

2016-05-29 Thread L.S.-Soc 

You also shouldn't paste blackboard characters as you did in your example.

Instead you should use \blackboard command -> check wiki. You will have 
to place it within a math environment though, so it might be wiser to 
read into "natural TABLES". -> also check wiki.


For example:

\startformula {\blackboard Hello World} \stopformula

or

\startformula {\blackboard R} \stopformula

I have a question about your code:

What prevents page break between heading the next paragraph?


a rather complex method of weighted penalties that also needs to make 
sure we don't break between successive heads but at the same time makes 
sure that we don't overflow the page



I might guess that is the two distinct options commandafter and after.
But this is only my suspicion on what may work there.

[NTG-context] Allow for hyphenation in 'firstline' ConTeXt feature ?

I use the nifty ‘firstline’ feature ConTeXt offers (using a larger font size,

There is a comment saying it could be added some option to handle disc nodes. 
I’d be happy to add such option but do not have enough knowledge in nodes 
manipulation in luatex, especially those related to hyphenation. Would it be 
very difficult to add such option please ?


I post a MWE showing some extreme non real non sensible case, to double check

Wolfgang,

many thanks for the improvement.

I have a question about your code:

What prevents page break between heading the next paragraph?

I might guess that is the two distinct options commandafter and after.
But this is only my suspicion on what may work there.

Many thanks for your help,

Pablo
