Dear list,

when I use a body font size other than the standard, issuing \vfill 
will move the content off the grid. MWE is below. How do I fix this?


Cheers, Henri

\setupbodyfont[9pt]
\setuplayout[grid=yes]
\showgrid
\starttext
Hello

\vfill

World
\stoptext


You can calculate the number of lines which have to be inserted to move 
the text
to the bottom of the text. The first step for this is to put the text 
which should be
moved into a \vbox which allows paragraphs and not only short texts. 
Afterwards
you can determine how much space is left on the page and with the 
\getnoflines

command you get the number of lines for the free space.

 begin example
\define\MoveToBottom
  {\par
   \dowithnextbox
 
{\scratchdimen\dimexpr\pagegoal-\pagetotal-\nextboxht-\lineheight\relax

  \getnoflines\scratchdimen
  \emptylines[\number\noflines]%
  \flushnextbox}
 \vbox}

\setuplayout[grid=yes]

\showgrid

\starttext

Hello

\MoveToBottom{World}

\page

\input knuth

\MoveToBottom{\input ward }

\stoptext
 end example

that's how vfill works, you can try \vskip30\lineheight with a value you like


Hm.  Then I'd like to reformulate my question:  How do I flush content to the 
bottom of the page when grid is enabled without having to specific how many 
lines to clear.


trial and error:

\vfilll \strut World \par \removedepth \page


This is not very satisfactory because it does not work unconditionally.  For 
instance with lucidaot it is still shifted off the grid.

\setupbodyfont[lucidaot,9pt]
\setuplayout[grid=yes]
\showgrid
\starttext
Hello

\vfill

World\strut\par\removedepth
\stoptext

I have come up with this other really hackish solution.  I just put the text on 
a layer and align this to the last line of the grid which I previously computed 
in Lua (Brrr).  Also, this has the disadvantage that text might flow into the 
layer (it's in the background).

\setupbodyfont[9pt]
\setuplayout[grid=yes]
\showgrid

\definelayer [flushbottom]
\setupbackgrounds [text] [background=flushbottom]
\edef\numberoflines{%
  \ctxlua{context(math.round(tex.dimen.textheight / tex.dimen.lineheight))}}

\starttext
Hello

\setlayer
  [flushbottom]
  [line=\numberoflines,location=grid]
  {World}
\stoptext

Is there really no way to have grid-consistent \vfill?  If there isn't please 
consider this a feature request.


not without some explicit support for it which currently is not there

\startstandardmakeup[top=,bottom=]
\strut Hello
\vss
\dontleavehmode\raise3\lineheight\hbox{\strut World}
\stopstandardmakeup









Cheers, Henri
