Seems to be a bug with \definelayout

Seems to be a bug with \definelayout

I’ve rewritten my last email. The context below produces the pdf in the screenshot below.

I expect the layout[short] to be applied to pages 2 and 3. It is. But there seem to be 2 bugs:

1 - Pages 4, 5 and 6 have the [short] layout. They should have the default layout.

2 - On pages 5 and 6, the text flows beyond the bottom of the frame. It should stop at the bottom of the frame.

Why do I think these are bugs? If I change the page number in \definelayout[3][short] to \definelayout[4][short], then it behaves differently and as I expect: only pages 2 and 4 have the [short] layout and the text flows within the frames.

Hi Peter,

as in my reply from yesterday, this seems to fix your bugs:

  \showframe
  \setuppapersize[A4][A3,landscape] \setuparranging[2SIDE]
  \setuplayout[backspace=80mm, width=100mm, topspace=50mm, header=0mm,
  footer=0mm, height=200mm, margindistance=10mm, leftmargin=40mm]

  \definelayout[short][backspace=80mm, width=100mm, topspace=50mm,
  header=0mm, footer=0mm, height=80mm, margindistance=10mm,
  leftmargin=40mm]

  \starttext
  \definelayout[even][reset]
  \definelayout[odd][reset]
  \definelayout[2][short]
  \definelayout[3][short]
  \dorecurse{10}{\input{knuth} }
  \stoptext

It seems that you need to reset the layout in all other pages (where the
special layout isn’t applied).

I hope it helps,

Pablo

There was a request (by you?) some days ago on stackexchange about
altering layout on say "six pages from here" (One can now do
\definelayout[+6][height=16cm]). Maybe something got changed regarding
the reset when one does \definelayout[n] to alter the nth page? I will
double check with Hans.
