Hans, thanks for responding.

I don't understand the above statement. What number of lines does 60
exceed? Is there a hard-coded limit? (We didn't seem to have a problem
with this code before we migrated from XeTeX / mkii to LuaTeX / mkiv,
but I couldn't guarantee what else is different.)

Is there a workaround for us now?
I could leave out the \setupcolumnsetlines commands for the moment, and
hope we don't overflow the page. Actually I'm not sure what will happen
if we leave the number of lines at the default (which is apparently zero?).

Regards,
Lars

Column sets allocates a box for each line but does that dynamically 
(i.e. at the start of a columnset) but the min/max settings in the above 
command don't check for that so if you have a 55 line layout you get an 
overflow.

I've added a check.

no, more like 55 or so (depends on the layout settings)

OK, I think I understand now.

I'm not sure what this means. I guess it will prevent the error message
from occurring.
Is it something I would get from a nightly development snapshot?
If so, where do I find it?

But it also sounds like there's no point in our having a setting of 60
lines when there are only 42 lines in our layout (that's the number
above which this error occurs). So I need to either tweak our layout, or
reduce the number of lines I'm asking for in a columnset.

Thanks,
Lars

Thank you. How can I make this change in our ConTeXt installations?
As noted previously, the only place I could find a mention of    /
     for i=1 upto NOfTextColumns-1/
was in some code that was already commented out. So I don't know how I
would comment it out any more effectively than that.

Jut to make sure it's clear, I'm running ConTeXt with mkiv.
(ConTeXt ver: 2012.05.30 11:26 MKIV fmt: 2013.3.11)

I mention that because I'm not sure if your statement about mkiv implies
that this error shouldn't be happening if I'm already using mkiv.

maybe there's something in a style?

It took me a while to figure it out as NOfTextColumns is only used in 
very special cases and long gone from context (it dates from a previous 
background implementation). Normally the obsolete code is never seen but 
in your case consulting the variable might be triggered by the fact that

multi_column_first_page_hack

is set to true (looks like a quick hack i made for Jelle long ago).

I commented it in the mkii source now, hopefully no error message any 
longer.

Hans

ps. sometimes there is some specific test code that then depends on 
other experimental code being present

ps. in mkiv it's all redone anyway and i will redo columnsets one of 
these days too;

error: terminal: >> NOfTextColumns-1, ! Improper final value has been replaced by 0

[Lars Huttar]

Hello,

I'm encountering the following error, under ConTeXt  ver: 2012.05.30
11:26 MKIV  fmt: 2013.3.11  int: english/english:

system > tex > error on line 27 in file
data/three-volume-book-book-1.tex: terminal: >> NOfTextColumns-1
! Improper final value has been replaced by 0.
<to be read again>
                   :
<*> for i=1 upto NOfTextColumns-1:
                                    draw (rightboundary TextColumns[i])
shif...


 ...

17 \safeinput ./data/statistics-for-area-area-africa.tex
18 \safeinput ./data/statistics-for-area-area-europe.tex
19
20
21
22 \input ./macros/E16pagenohead.tex
23 \ifodd \pageno \else \noheaderandfooterlines \null \page[yes]\fi
\noheade
randfooterlines
24
25 \startptp{
26 \pagereference[Languages]\pnum{Part II}\ptitle{Language Listings}
27 >> }\stopptp


This error is very odd because:

a) The only place I can find code mentioning "NOfTextColumns-1" is in
mp-core.mpii, where it's commented out!
  % \startuseMPgraphic{whatever}
  %     for i=1 upto NOfTextColumns-1 :
  %         draw (rightboundary TextColumns[i]) shifted ...

But maybe I just haven't been looking in the right places.

b) The place in my .tex document where the error occurs, line 27, is at
a \stopptp. Yet there is an essentially identical start/stopptp earlier
in the document, where no such error is thrown:

  \startptp{
  \pagereference[Summaries]\pnum{Part I}\ptitle{Statistical Summaries}
  }\stopptp

So I guess there's some content in between the two starts/stop ptp's
that's laying the stage for the error to occur.
I'll be working on a minimal example, but that's time-consuming; and I
thought in the meantime, there may be some clues in the above
information that could help clarify the nature of the problem, to
someone who understands the inner workings of ConTeXt.

Thanks for any help,
Lars
