[NTG-context] \pushbackground for header/footer

[Mohammad Hossein Bateni]

Hi,

Can one use {push,pop}background to save/restore backgrounds for
header*text and/or footer*text areas?  I'm trying to typeset a document
where one page has a special background, which I set using
\setupbackgrounds[header][text][background=color,backgroundcolor=gray].
Can I go back to the default setting afterwards or do I need to specify it
explicitly.  I know I can save whatever I put in \setupbackgrounds[page]
using \pushbackground[page] and \popbackground.  I could not get it to work
with header/footer.

\setupcolors[state=start]
\showframe
\setupbackgrounds[header][text][background=color,backgroundcolor=yellow]

\starttext

One
\page

%\pushbackground[page]

\pushbackground[header][text]
\setupbackgrounds[header][text][background=color,backgroundcolor=gray]

Two
\page
\popbackground

Three
\stoptext


Thanks,
MHB

[NTG-context] hz in MkIV

[Mohammad Hossein Bateni]

Hi,

In MkIV, the syntax for using hz seems to have changed from
\setupfonthandling to \setupfontexpansion (similarly for protrusion).  What
is the equivalent of the following?  Is this feature supported in MkIV and
LuaTeX?  I tried changing/adding entries to
fonts.expansions.vectors.quality (and .default) to no apparent avail.


\startfonthandling [hz]
  \defineadjustfactor A .5
  \defineadjustfactor B .7
  \defineadjustfactor C .7
  ...
\stopfonthandling


In any case, I'm happy that hz works for Arabic/Farsi despite some warnings
suggesting the contrary (
https://mailman.ntg.nl/pipermail/ntg-context/2008/029765.html).  It does
make certain Farsi texts look better, however, support for tatweel/kashida
would be ideal.  In fact, I was trying to see if I could somehow get it to
work, building on top of hz.  Hans, do you have any suggestions for this?
Would this be feasible and/or worth trying?

I once converted Vafa Khalighi's XeTeX-based code to Lua but ran into
several setbacks.  (The idea is to insert a sequence of
(ZWJ,\nobreak,stretchable leader,\nobreak,ZWJ) between certain character
pairs that join one another.)  Here are some of the issues I faced:
1) This could not be turned off and on within a paragraph because I was
hooking into processors.before action.
2) The mechanism for some (all?) center alignments (including default
figure captions) interferes with what I was hacking (or, to be more
precise, it's the other way around) and causes unnecessary use of tatweel
in those settings.
3) Later I noticed that the added sequence did not inherit many properties
(like font style or color).
4) The optimum values for the stretches I put in depend on the context,
particularly because some environments manipulate \spaceskip for other
reasons.

Sorry for the mumbling.  I can explain more if anyone is interested in
helping to improve this functionality.  Attached is what I have now.

Thanks,
MHB

I think i fixed it (no upload yet) but this kind of tricky things 
probably need some time to get sorted out.

Re: [NTG-context] Equivalent of extras option in new bibliography system?

Yes. Consider:

\cite[righttext={{, p.~24},{, p.~xx}}] [Author:2016,Author2:2015]

The comma gets parsed (as always) to separate multiple right texts,
assigned here to each citation reference.

The solution to your problem is:

\cite[righttext={{, p.~24}}][Author:2016]

Alternately (if you find the {{ }} strange), you can type
\cite[righttext={\btxcomma p.~24}] [Author:2016]

The macro \btxcomma also takes care of spacing.


I know I shouldn't be asking but answering questions on this topic, but 
here comes anyway: what is the magic incantation to have the righttext 
included within the brackets in authornum styles? So for


\cite[righttext={{,\,100}}][Hagen]

I want the result to look like Hagen [1, 100]. I tried

\definebtx
  [default:cite:author:num] % todo
  [default:cite:authornum]
  [left={\btxleftbracket},
   right={\currentbtxrighttext\btxrightbracket}]

but I get Hagen [1], 100. Any pointers what I should try?

Amazingly, this has also fixed a long-standing bug I had with one of my

minimal example to reproduce it, so I'm very glad Marco did, thank you

You probably had to include 
/Applications/LilyPond.app/Contents/Resources/bin
into $PATH.

This PATH is only known in the Terminal.
When you call ConTeXt from the GUI (via TeXShop) you only have the default PATH.

Since TeXShop calls context via an engine file, you can add the PATH in the 
engine:

Change this line (actual path to context may differ):

set path= (/usr/local/texlive/context/tex/texmf-osx-64/bin /usr/local/bin $path 
)

to

set path= (/usr/local/texlive/context/tex/texmf-osx-64/bin /usr/local/bin 
/Applications/LilyPond.app/Contents/Resources/bin $path )

You will find the engines in:
~/Library/TeXShop/Engines
