delimitedtext, spacebefore and grid

delimitedtext, spacebefore and grid

[Oliver Heins]

Hello,

I want to have both a halfline space before and after blockquotations.
Normally, this works fine; after the quotation the main text snaps
back to the grid (see page 3 of the example file).

\setupdelimitedtext
  [blockquote]
  [spacebefore=halfline]

However, this fails when the blockquote is the first element on the
page, either because a new blockquote starts on the top of the page
(cf. p. 1) or because a blockquote continues from the last page
(cf. p. 2).  Is it possible to tell ConTeXt to insert a halfline of
space on the top of the page in these cases?

TIA,
 olli


\setuppapersize[a5][A4]
\setuplayout[location=middle,marking=on,grid=yes]
\setupbodyfont[14pt]

\setupdelimitedtext
  [blockquote]
  [spacebefore=halfline]

\showgrid

\starttext

\startblockquote
  \input tufte
\stopblockquote

\dorecurse{2}{\input tufte}

\startblockquote
  \input tufte
\stopblockquote

\dorecurse{3}{\input tufte}

\startblockquote
  \input tufte
\stopblockquote

\input tufte

\stoptext

Hello Wolfgang, thank you for your answer.  Sadly, your solution only
works for blockquotes starting at the top of the page.  When blockquotes
are broken up between two pages the main text doesn't find its way back
to the grid (see page 2 of my minimal example).

Another point is: The space inserted at the top of the page is not a
half line big but of one and a half line.

Thanks, it was a typo.  I already wondered about how huge an A5-sized
page in ConTeXt is :) However, the setup of my minimal example
illustrates the problems best on A4, so *here* it should read either
\setuppapersize[A4] or nothing (since A4 seems to be the default
anyway).

Best regards,
 olli

I think I've discovered another little problem of the same sort if directly after the quotation a blank line is requested:

---
\setuplayout
    [grid=yes]

\setupdelimitedtext
    [quotation]
    [spacebefore=halfline]

\showgrid

\starttext

\input tufte

\startquotation
    \input tufte
\stopquotation

\blank
\input tufte

\stoptext
---

Unfortunately the trailing main text doesn't align with the grid either. Any solution to both problems?

Best wishes,
Oliver

Just wanted to ask whether anyone has looked into these issues… a solution would be much appreciated (and put to immediate use in a current project ;-)

Not sure if there are side effects but this works (requires mkiv and a recent installation):

\setuplayout[grid=yes]\showgrid
\setupbodyfont[14pt]

\usemodule[annotation]

\define[2]\ZitatCommand
  {\topskip\dimexpr\topskip+\lineheight/2\relax
   \startnarrower
   “#2”%
   \stopnarrower}

\defineannotation
  [zitat]
  [alternative=command,
       command=\ZitatCommand,
   spacebefore=halfline,
    spaceafter=halfline]

\starttext

\startzitat
\input tufte
\stopzitat

\dorecurse{2}{\input tufte\par}

\startzitat
\input tufte
\stopzitat

\dorecurse{3}{\input tufte\par}

\startzitat
\input tufte
\stopzitat

\input tufte

\stoptext

Indeed, this solves the grid issue for block quotations broken across pages. Many thanks!

Unfortunately introducing a "\blank" just before the last "\input tufte" in the above example breaks grid alignment.

The afterspace-value from \stopzitat is ignored with your \blank and you get only one empty line while you need one and a half (one from the \blank command and a half from \stopzitat).

Nevertheless you can force the correct value with \blank[halfline,line]

Sure, that's a good workaround.

In the long run would it be possible in grid mode to have \blank insert 1+x lines of vertical space where x is adjusted such that the following material is aligned on the grid?

… or simply make it not swallow the previous halfline correction from the quotation?

Took me a while but this does what you want:

\blank[line,category:4]
