Exactly. But I wanted to discuss the idea to adapt the width of the text area 
(\textwidth) or maybe the width of margins (the marginals area that ConTeXt 
calls margin) to the page shift, so that the optical width of the margins (what 
ConTeXt calls edges) stays the same.
As far as I know, nobody ever did that - of course, it’s a major effort for 
little gain, and it complicates TeX’s line breaking, the engine would need to 
know about imposition while breaking lines.
But since we can have snake-justified text, I thought I could bring up the idea 
;)

Oh yes, thank you!
I knew there was already a solution for the ususal creep, but I couldn’t find 
it, was expecting a parameter of \setuparranging or the like.

But that doesn’t reduce the line width for shifted pages.

Re: [NTG-context] Creeps (binding gutter / margin correction in imposition)

[Willi Egger]

Hi Hraban,

I am not sure about what you say. The page shifting/creep correction is added 
individually per spread. If this is done correctly then the typeset area is on 
all pages the same width and has after folding and cutting  the same outer 
margin. 
As Wolfgang reports look into \definepageshift cum suis.


Kind regards

Willi

Hi together,

this is not really a practical request, but an interesting (I think) 
idea...


ConTeXt can do simple imposition (arranging pages on sheets, see 
\setuparranging), but in professional imposition you need to 
compensate for the paper thickness in folds to keep pages readable - 
you can move the outer pages of a fold out of the gutter (spine), or 
move the inner pages to the spine. (This is called creep in English, 
Bundversatz in German.) That means, your outer margin will have 
different width, depending on the position of the page in its fold.


See e.g. https://helpx.adobe.com/indesign/using/printing-booklets.html

A guy on the LilyPond mailing list had the interesting idea to adapt 
the line width to this creep, to keep an even outer margin - it would 
mean that TeX needs to know about imposition while breaking lines.


What do you think?

Re: [NTG-context] Clickable question/answer numbers

[Otared Kavian]

Hi Dalyoung,

Yes I see what your problem might had been. Recently ConTeXt creates a fine 
named FILENAME.tuc when one typesets FILENAME.tex. This *.tuc file creates 
difficulties when the typesetting is stopped for some reason or another, 
because then at times it is impossible to typeset again the same file even if 
the error has been fixed.

Maybe we have to ask Hans whether this behavior is intended or not: in any case 
one has to remove that *.tuc file manually in order to typeset again.

Best regards: OK

[Jeong Dal]

Dear Otared,

It is not the problem of your code. 
Strangely, the code you just sent to me is stopped by the same reason during 
the compilation
even though it does not contain the word “myanswer”.
After removing *.tmc file, the error disappear.  
I still don’t know why such an error occurred.

Anyway, I got a nice sample which is very useful.

Thank you.

Best regards,

Dalyoung
