Hi,

There is a subtle bug with \adaptlayout.

\adaptlayout[1][height=max] does not work, e.g.,

\showframe
\adaptlayout[1][height=max]
\starttext
\dorecurse{10}{\input knuth \par}
\stoptext

but \adaptlayout[2][..] etc work. The reason is the following.
Typically, we use \adaptlayout[...][...] before \starttext at which
point \realpageno=1.

Now, \page_adapts_layout calls \page_adopts_check which checks if
\??pageadaptions\the\realpageno is set. If so, it calls the
pageadaptions and resets it to relax.

Since all this happens before \starttext, it does not affect the first
page.

I am not sure what is the best way to fix this.

[NTG-context] Bug with adaptlayout

2013-09-12 Thread Aditya Mahajan

Hi,

There is a subtle bug with \adaptlayout.

\adaptlayout[1][height=max] does not work, e.g.,

\showframe
\adaptlayout[1][height=max]

but \adaptlayout[2][..] etc work. The reason is the following. Typically, 
we use \adaptlayout[...][...] before \starttext at which point 
\realpageno=1.


Now, \page_adapts_layout calls \page_adopts_check which checks if 
\??pageadaptions\the\realpageno is set. If so, it calls the 
pageadaptions and resets it to relax.
