Re: [NTG-context] \definelayout

28 Dec 2011

      Update with a minimal working example.

If a layout is specified for the first page
(\definelayout[first][...=...], that specification is carried on
through all subsequent pages; the layout does not return to the
default specified with \setuplayout[...=...] on the second page.

If a layout is specified for a single later page
(\definelayout[3][...=...]), that specification is carried on too. In
the case of header/footer size, the body text overruns the footer area
on subsequent pages. In the case of backspace (text width), the first
paragraph on the page with the new layout is the default layout width
but the rest are OK. (I have seen this width issue mentioned before
and it may not be possible to change this behavior, but the
header/footer size is a problem for me.)

Thanks.

The example is not working correctly for me with the 23 Dec. beta. If
I set a larger footer size for the first page, that larger size is
carried over to all the rest of the document.
Here's my code:
\setuplayout[%
 width=middle,
 backspace=15mm,
 topspace=10mm,
 height=254mm,
 header=5mm,
 headerdistance=5mm,
 footer=5mm, % Normal footer size
 footerdistance=5mm,
 grid=tolerant]
\definelayout[first][% Larger footer on first page
 footer=15mm,
 footerdistance=5mm]

Hi all,
would someone please enlighten me. What is the correct usage of \definelayout?
\definelayout[default][width=middle,height=middle,header=0pt,footer=0pt]
% \setuplayout[default] % needed?
\definelayout[first]  [default][header=2cm]
\definelayout[unknown][default]%[reset]
% \definelayout[2]      [default]%[reset]
\definelayout[last]   [default][footer=2cm]
\starttext  \showframe % \checkcurrentlayout
%% Variant A: fails with \default[unknown]
first\page unknown=(2)\page \page unknown=(3)\page last
%% Variant B: fails with \definelayout[2]
% first\page unknown=(2)=last
\stoptext
By the way the output differs with the latest beta in comparison with the latest experimental.
Hans changed part of the \setuplayout code in the last betas (there are more than you can see in the ctx suite).
When context checks the layout (happens with \starttext and when it starts a new page) it test for the following defined layouts:
• “<pagenumber>”
• “-<pagenumber>”
• “last” (is only used for the last page of the document)
• “first” (is only used for the first page of the document)
• “unknown”
• “current”
• “odd” and “even” (used for left and right pages)
All entries in this list are reserved names but you can also define your own layout but in this case
you have to enable it with \setuplayout[<name>].
One of the new features in MkIV is that layout parameters can be inherited, e.g. when
you define a layout with the name “one” {\definelayout[one][..,..=..,..]) and another one with
the name two (\definelayout[two][one][..,..=..,..]) this will take the values from one of there
are nothing set for a value from one and when there is also nothing set for one the global
values are used (\setuplayout[..,..=..,..]).
Hi Wolfgang,
I modified the example (hopefully in a meaningful manner). I get the desired output with the old beta, but it still fails with todays beta.
\setuplayout [width=middle,height=middle,header=0pt,footer=0pt]
\definelayout[first]  [header=2cm]
\definelayout[last]   [footer=2cm]
\definelayout[current]
\starttext  \showframe % \checkcurrentlayout
 % \dorecurse{2}{test\page} % last is wrong
 \dorecurse{5}{test\page} % page 2 and „last“ are wrong
\stoptext
