Following up on the other imposition question, I'm trying to make an example file that shows an imposition schema according to command line arguments.
This way it works for the number of pages, as used in \dorecurse{\Pages}{…}, but not for the imposition schema. Typesetting \Schema looks right, but \setuparranging doesn’t work. Where's my error?
You forgot about expansion and in your case \doifelsedocumentargument is not fully expandable. This doesn't matter for \dorecurse where the number parser ignores the flag because \setuparranging does care and \Schema fails to expand.
\def\Schema{\doifelsedocumentargument{schema}{\getdocumentargument{schema}}{1*8}}
\def\Pages{\doifelsedocumentargument{numberofpages}{\getdocumentargument{numberofpages}}{16}}
\setuparranging[\Schema]
\doifelsedocumentargument{schema} {\setuparranging[\getdocumentargument{schema}]} {\setuparranging[1*8]} It does also help to look at the included extra files (e.g. mtx-context-arrange.tex) written by Hans. Wolfgang
