Hello list,
I would like ConTeXt to snap normal text to grid after a quotation.
This example does not work:
--------------
\setupquotation[before={\switchtobodyfont[9pt]}]
\starttext
\showgrid
\input knuth
\startlinecorrection[halfline]
\startquotation
\input sapolsky
\stopquotation
\stoplinecorrection
\input knuth
\stoptext
--------------
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?
Thanks,
Massi

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. It would be nice to have an alternative that does not have that limitation. -- Rik On 2017-09-28 18:35, mf wrote: > Thank you Henri, > a slightly modified version of your solution works! > > This is what I wanted to achieve: > > \setuplayout[grid=both] > \setupquotation[before={\switchtobodyfont[9pt]}] > > \starttext > \showgrid > > \input knuth > > \startlinecorrection[halfline] > \startquotation > \input sapolsky > \stopquotation > \stoplinecorrection > > \input knuth > %\vadjust pre{\blank[line]}% not line, but halfline! > \vadjust pre{\blank[halfline]}% > $\displaystyle{\frac{1}{a + b}}$ > %\vadjust{\blank[line]}% not line, but halfline! > \vadjust{\blank[halfline]}% > \input knuth > > \stoptext > > In general, I'm ok without grid snapping, because the default > typesetting of taller formulas inside text is good enough for my goals. > > 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. > > But sometimes grid snapping is too strict, as in the tall formula > example.

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.

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 ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 14+ messages in thread

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 ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 14+ messages in thread
