Hello list, sometimes ConTeXt moves the (would-be) last line of a page to the next page, even when there's room for it at the bottom of a page, before the footnotes.
Sometimes i understand why it does so: when the line contains a footnote that would increase the footnotes' height, for example; or when you have widows or orphans.
But sometimes it happens in an inexplicable way: in some pages there's room at the bottom and it keeps the last line, in some other pages there's more room (than in the previous case), but it moves the last line to the next page anyway. Even looking at hyphenations, i can't find an explanation fot that behaviour.
you can mess with penalties but at somepoint tex has to decide ... an option is to use \adaptlayout and make the page a line higher, another is \starttext \showframe \dorecurse{22}{line #1\blank} % \dorecurse{24}{line #1\blank} \keeplinestogether{100} \input klein \stoptext but of course there can be side effects
So i'm looking for a way to prevent ConTeXt from moving the last line to the next page.
A solution i found is to insert a \vadjust{\kern -0.5pt} in the second-last line of the page. It works -- see the attachments -- but it modifies the interline, so it's feasible only for corrections under 1pt.
Another way would be locally shrinking the space before footnotes, but i don't know how and when to do it.
Some words about the attachments:
- there are some footnotes and line height setups to resemble the real configuration i'm working with
- keep-line-in-page-0.tex is the reference case
- keep-line-in-page-1.tex is the solution with \vadjust{\kern -0.5pt}
Best wishes, Massimiliano
