Syntax
| \doloop{commands} | |
| {commands} | Commands or text to repeat |
Description
Repeat indefinitely; stop after a loop in which \exitloop is encountered, or immediately when \exitloopnow is encountered.
Example
\setuppapersize[A10, landscape][A8, landscape] \setuppaper[nx=2, ny=2] \setuppagenumbering[location=footer] \setuparranging[XY] \showframe[edge] \starttext \dorecurse{4}{ hello\crlf \doloop{ \ifnum \pagenumber=\recurselevel \exitloop \fi bla } \page[yes] } \stoptext
