1. The usage of the command "\definepagestate " is what I searched for in
previous posts and source files.
I don't know exactly how he used it. (╥﹏╥)
2. I've devised a command that needs to get the current page number to
determine if it's an odd or even page.
This is then used to get a certain width to determine the width of the command
on that line.
Below I designed the command. The code related to this issue is mainly
You have to differentiate between odd and even and right hand and left
hand pages.
When you want to check whether you have an right hand or left hand page
you can use the following method.
To get the correct result ensure you start a paragraph before you set
the flag with \signalrightpage.
%%%% begin example
%\setuppagenumbering[alternative=doublesided]
%\setuppagenumbering[alternative={singlesided,doublesided}]
\starttext
\dorecurse{20}
{\dontleavehmode\signalrightpage\doifelserightpage{\bold{Right
page}}{\bold{Left page}}
\samplefile{lorem}}
\stoptext
%%%% end example
To have a check which works for odd and even pages you have to use the
pagestate mechanism.
Even in this case it is important to start a paragraph before save the
current state, afterwards
you can check the stored pagenumber.
%%%% begin example
\definepagestate[warichu]
\starttext
\dorecurse{20}
{\dontleavehmode\autosetpagestate{warichu}%
\ifodd0\autopagestaterealpage{warichu}%
\bold{Odd page}
\else
\bold{Even page}
\fi
\samplefile{lorem}}
\stoptext
%%%% end example
