When you want to change the structure of your document when using
structure levels, all that you need do is add or subtract a level of
nesting. With named levels, it is easy to create complicated documents
that jump around in level, which would be pretty messy.


on the other hand, when you look at a piece of coded document you no 
longer know if you're in an important chapter or unimportant 
subsubsubsubsubsubsection


so, in the end it all boils down to circumstances and usage which is why 
we have several methods



What a nightmare it would be to add or subtract a named structure level
in a complicated document.

This being said, I still mostly use named structure levels myself, as
old habits are hard to change (but don't tell Hans this!).


ha, well, if i remember right this nested anonymous sectioning was added 
on your request .. so it is now one of those orphaned features


anyway, i tend to replace

\chapter{foo}

by

\startchapter[title=foo]

\stopchapter

but at a much lower level keep using \subsubsection and alike

(also because then with chapters one can more conveniently set other 
properties)

the main benefit from using \startchapter ... \stopchapter instead of

In my output I can see overful of the last line on pages 38-46.

How can this happen? Isn't it a clear bug?

What exactly mean 'that amount start interfering with an optimal
solution'? Isn't parfillskip settings taken already into an
account when composing the paragraph?


it's just a skip added at the end of the line ... so like any skip
and if you give it a fill that will be taken into account in
linebreaks (just like other fill)

\starttext

\dorecurse{100}{testtesttesttesttest #1 \hskip0ptplus1fill\relax}

\stoptext



To be honest, I can't still decipher the reason why the line is not broken...

We basically need:


and I thought this is exactly what \parfillskip ensures
\parfillskip XX plus (hsize - 3*indent)

Or is it impossible in TeX to achieve such rule?


the fil is taken into account when calculating the best break points and 
then the XX is fixed but plus/minus can lead to if being less or more, 
all relative to other fill (distributed)


so, XX plus (hsize - 3*indent) is not a fixed value, it's XX or more

take this:

\ruledhbox to 10cm {x\hskip0pt plus 1cm x}

the skip will stretch more than 1cm

\ruledhbox to 10cm {x\hskip0pt plus 1cm\relax x%
x\hskip0pt plus 2cm\relax x}

now the glue gets distributed 1:2, so now you can guess

\ruledhbox to 10cm {x\hskip1mm plus 1cm\relax x%
x\hskip8mm plus 2cm\relax x}


Are there other ways? I can think of:


But in this case that space at the end can be completely swallowed (by negative 
glue). I've tried it in the following example, but there is another problem 
from page 58 - blank line. But my TeX interpretation of the above pseudo code 
may be inappropriate...


you can see what glue eventually is used with:

\showmakeup[glue]

\start

\parfillskip  123pt   \relax \input tufte \par
\parfillskip  123pt plus 1fil \relax \input tufte \par
\parfillskip  123pt   \relax \input tufte \par
\parfillskip -123pt plus 1fil \relax \input tufte \par

I agree. That chapter is confusing if you do not know already how the

I tried to create the first example of the

but failed with mkii and iv. The page is created,
but without the graphical elements. Not using
\startbuffer--\stopbuffer makes no difference.



You are simply setting the positions. You also need to tell ConTeXt to do
something with the positions.

1. First define a position graphic that does something with the anchors that
it is passed.

\startMPpositiongraphic{mypos:arrow}
   pair c[] ;
   initialize_box(\MPpos{\MPvar{self}});
   c[1] := cxy ;
   initialize_box(\MPpos{\MPvar{to}});
   c[2] := cxy ;
   drawarrow c[1] -- c[2] withpen pencircle scaled 2bp ;
\stopMPpositiongraphic

cxy is the center of the box. See the defn of initialize_box in mp-core.mp
for other values. I wish these were better documented.

2. Then define a position overlay that specifies the relation between the
anchors.

\startpositionoverlay{arrow}
\setMPpositiongraphic{X-1}{mypos:arrow}{to=X-2}
\setMPpositiongraphic{X-2}{mypos:arrow}{to=X-3}
\stoppositionoverlay


3. Define an overlay that is mapped to MP position overlay.

\defineoverlay[arrow][\positionoverlay{arrow}]

4. Hook the overlay as a page background

\setupbackgrounds[page][background=arrow]

5. Then everything will work.

\starttext

Re: [NTG-context] metafun

2016-03-24 Thread Piotr Kopszak
Hello list,

The solution shown here no longer works with recent beta (indeed, it
probably ceased to work some time ago). How should it be corrected?

Best

Piotr

Re: [NTG-context] Why does 0.0001pt make such a big difference?

Why is there such a difference please?


because the zero glue is discarded (in context) due to another one 
taking precedence; i'll be a bit more tolerant but i'm not sure of side 
effects


(for now using 1sp plus 2ex is quite ok)

I think that two, three, four are not very descriptive. An easier to
remember interface could be \setupalign[3*parindent], etc.


- i don't wanted new keywords

- we don't scan for n* in setupalign (and "3*parindent" could be a 
keyword of course but messes the interface)
