Re: [NTG-context] Position of prime for derivatives

2017-06-04 Thread Otared Kavian 
Hi Mikael,

Indeed your observation is correct, but using \over instead of \frac yields the 
correct behavior. Please try the following sample:

%%% begin derivatives-prime-4.tex
\setupbodyfont[lucidaot]

\starttext

Compare the position of the prime sign in $f'/g$ in these two expressions: the 
first one using \type{{... \over ...}}
\startformula
\left({f \over g}\right)' = {f' \over g} - {f \over g^2}g'
\stopformula
(which yields a correct position of the prime for $f'$ in $f'/g$), and the 
second using \type{\frac{...}{...}}
\startformula
\left(\frac{f}{g} \right)' = \frac{f'}{g} - \frac{f}{g^2} g'
\stopformula
which yields a prime sign for $f'$ a little bit lower.

\stoptext
%%% end derivatives-prime-4.tex

 Hi Mikael and Otared,

 I can confirm issues regarding primes, too. If you are using the STIX 2
 fonts (http://www.stixfonts.org) and my example below you get a somewhat
 strange behaviour of primes that is pretty obvious. I think the issues
 should be fixed.

 By the way the issue seems to depend to some extend on the fonts. Using
 Lucida by \setupbodyfont[lucidaot] it is not that obvious but still 
 present.
 Using Latin Modern it seems that the spacing between the primes changes
 between f'' and f^{''}. Cambria seems to show that behaviour (like Latin
 Modern), too, but less obvious.

 Best regards
 Mathias

 Hi Mikael,

 You are correct, the position of \prime depends on whether there is a next
 character or not after it, and it seems that this has an effect on its
 position for characters having a subscript as in
 $f_{1}''(x) \neq f''_{1}(x)$
 $f'f''f'’'$
 Best regards: OK

 Hi Mikael,

 I agree with what you are reporting: the current behavior of the \prime
 operator is not completely satisfying when using ConTeXt mkiv, while in 
 mkii
 it is the most satisfying (in my opinion…).

 The turn around consisting in using $f^{‘’}$ or  $f^{\prime\prime}$, or 
 even
 $f^{{}^{\prime\prime}}$, is not really satisfying either.

 But I think (or I hope that) at some point Hans will fix it in mkiv.

 Best regards: OK

 And just for reference, the document below gives the attached pdf,

 better. Sorry for spamming about this issue, but I think it is

[NTG-context] synctex

2017-06-04 Thread Hans Hagen 

Hi,

For those using synctex, an alternative method is:

\setupsynctex[state=start]

It is tuned for use in a more complex setup where one wants access to 
source files (with content) and not to e.g. styles in a tex tree. It 
also works reasonable well with (also included) xml files. Personally I 
never use synctex but for some projects it came in handy for authors 
(think of proofing xml files with hundreds of nested inclusions and 
files in a rather branched tree.) Of course you can expect a similar 
performance hit as normal synctex but commenting the above line in 
production results in zero overhead. Using the syntex flag on the 
command line (--synctex=context will work) can be messy.


This currently only works with the windows binaries version on the 
garden (as we need luatex 1.0.5).

Re: [NTG-context] overrule italics

I have a long text with section headers partly in italics and/or

\setuphead[section][style=\tfb\up]

In LaTeX there would be \upshape/\textup -- is there an equivalent in 
ConTeXt?


Did you try \tf ?



yes I did, unfortunately it doesn't work


Otherwise \emph{italics \emph{upright} italics} should work (didn’t try).


Nested emph to invert works. But my text has both italicised and regular 
headers -- both should be printed upright with the modified style.


Even though I can modify them manually in this present case, something 
like \upshape would be good to have.
I uploaded a beta with a new option (in addition to an old one). I need 
to discuss with Wolfgang etc what default makes sense (topic for 
upcoming context meeting).

Re: [NTG-context] align inner items vertically

Hi,

is it possible to align the inner itemgroup vertically with the outer
enumeration, even if there is a "big" math expression? See the example
below (where I have made the enumeration serried, just to see the
_vertical_ misalignment better)? I think I miss something simple, but
looking in setup-en.pdf I cannot find the necessary key.

this is rather nasty code but i'll see what i can do

[NTG-context] aligning external figures

2017-06-04 Thread Pablo Rodriguez 
Dear list,

I have the following sample:

\setupexternalfigure[location=default, align=middle]
\starttext
\dontleavehmode\externalfigure[cow.pdf]

\externalfigure[cow.pdf]
\stoptext

As you can see, \dontleavehmode makes no difference.

Does anyone know how the align key in \setupexternalfigure works?

Many thanks for your help,

Pablo
