Question on headings and text around them

Question on headings and text around them

[-- Attachment #1.1: Type: text/plain, Size: 1090 bytes --]

Dear all,


In some text I am typesetting I noticed that the text following a section was always starting on same page (which is all fine), but in some cases the text preceding the section heading was also finishing on same page, ie the last paragraph before the section heading was broken in previous page, say N lines on previous page and 2 in the page in which the section starts (I have \widowpenalty10000 that’s probably why there are 2 lines in new page), even if there is space in the previous page for the 2 lines (there are even 3 blank lines at the end of the page).


Apparently I could solve this “problem”, adding some 0 penalty:


\definevspacing[BeforeHeading][penalty:0]


\def\BeforeBook{\blank[BeforeHeading, line]} % was \def\BeforeBook{\blank[line]} which seems to avoid breaking page between text before heading and heading itself


\setuphead[section][before=\BeforeBook]


My question is simply, is that a correct way to fix the problem, or is that just “luck” this fixes the issue ?


Thanks a lot,


Best regards


Joseph Canedo

you need to make a (minimal) example that shows the issue

Hans,


Thanks for replying, Actually I realise the problem is with column break (was a bit late when I wrote my message, sorry for this).


I prepared a small example + output I get.


I am not saying the output is necessarly bad, but I’d like to know how to avoid the paragraph being broken and the 4 empty lines in the first column (at least in the example), or know what I am doing wrong. It looks like there is some setting “attaching” the last 2 lines of paragraph to the next section heading.




Thanks




Best regards




Joseph

Et le peuple estoit attendant Zachariah : & sesmerveilloient quil tardoit tant au temple. Et quand il fut yssu hors/ il
ne pouvoit parler a eulx. Lors congneurent quil avoit veu vision au temple. Et il leur donnoit a entendre par
signes : & demoura muet.
