Now the text snaps to the grid after the quotation, but the tall formula inside the text overlaps with the text lines.

The solution would be a grid configuration that gives the line containing the formula two lines of height, putting that only line in the middle and then snapping the following lines again to the grid (still solving the alignment of quotations as in the grid=both case). Is it possible?

Hello list,  I would like ConTeXt to snap normal text to grid after a quotation. This example does not work:

If I prepend a \setuplayout[grid=yes], it works, but grid snapping introduces also other side effects I don't want (i.e. tall formulas inside text taking too much vertical space).

I would like the halfline spaces before and after the quotation to shrink or stretch a bit to the nearest multiple of the main text line height.

Is there an automatic way to get the normal text "return" on the grid after a quotation without turning on a global grid snapping?

\setuplayout[grid=both] to round down both height and width when snapping.

If you are really keen on screwing up your linespacing you can use

as a one-off solution.  But better make it a displayed formula or tweak it such that it does not disrupt spacing and blends in with the text.  In this example I'd change $\displaystyle\frac{1}{a + b}$ to $(a+b)^{-1}$.  Trust someone who does math typesetting every day.

Massi and list,

There is one issue with \startlinecorrection of which you should be aware. The text is set in a vbox. If the block quotation it encloses (or whatever text it encloses) does not fit on the current page, a page break will be generated. This makes it useless with quotes near the bottom of a page. Enclosed texts longer than a page run over the bottom margin of the new page.

Thank you Rik, I overlooked that (and now I'm reading Hans' reply about line correction being for framed material and not for quotations). I need to decide whether to - turn off grid snapping and adjust every single quotation or - turn grid snapping on, benefit from line correction most of the time and manually adjust the cases where a quotation is across a page boundary It depends on the texts I'm working on. This question reminds me the chapter about line profiling in the "Still" manual. There's no general, fully automated solution.

It would be nice to have an alternative that does not have that limitation.

Hans talked about that at the last ConTeXt Meeting. If I understand well, it's very hard to calculate how much of the vertical space of the page TeX has used. And once it flushes the page, it frees the memory and forgets about it. Add inserts like footnotes to the problem and it gets really hard. Best regards, Massi

In general, I'm ok without grid snapping, because the default typesetting of taller formulas inside text is good enough for my goals.

for a bit more complex doc with many different unpredictable elements snapping seldom works ... we never use it (in production it often leads to more whitespace than one wants) ... the tex glue model is good enough (the requirement often comes from cases where snapping is the only way to get spacing right ... similar to the use of ragged right and no hyphenation because the used system can't handle it well ... in the worst case the limitations of a system then become undisputable 'good practice' and 'it's the default' and 'it's better for reader' etc)

But I have many quotations (and floats), whose spaces before and after should be manually tuned not to push the main text out of the grid. And here grid snapping does a very good (and automated) job.

So for quotations and adjust the space around them are you suggesting manual adjustment?

I was already more convinced of keeping snap-to-grid turned off. Now the problem is how to adjust the spaces around quotations (and floats) at the minimum cost.

Since the line heights of the main text and the ones of quotations do not change, the adjustment depends only on the number of lines of quotations. I could compile a table for more common cases:

# of lines | adjustment 1 line | ... pt 2 lines | ... pt 3 lines | ... pt ... 20 lines | ... pt

I should teach users how to insert adjustments, but the task would be eased because they should only copy a value from a table or insert a name that corresponds the the number of lines (i.e. "adjust-3-lines", "adjust-4-lines", etc.)

Greetings, Massi ___________________________________________________________________________________

Be careful not to insert an adjustment after a block that is split over two pages. A more useful (from a user perspective, I do not know about the coding) solution would be a command to snap to the nearest grid line (up or down, half or whole step). But both your count and my \snapto suffer from a common problem. Both are likely to leave different amounts of space before and after the block. A more evenly balanced approach is to compute the height of the block plus the vertical space by which it should be set off plus the vertical space needed to reach a grid-line or half-grid and, if the block stays on the page, split the difference top and bottom. If the block does not stay on the page, some portion with the top offset must be calculated and placed on the page if it otherwise meets widow/orphan tests. -- Rik
