Description

\definebreakpoint[setname][?][...=...] defines a breakpoint at ?, and makes it a member of a set that can be activated with \setbreakpoints[setname]. The set must be initialized with \definebreakpoints[setname].

Example

This is how the compound breakpoint set is defined in typo-brk.mkiv

\definebreakpoint [compound] [+] [nleft=3,nright=3,type=1]
\definebreakpoint [compound] [-] [nleft=3,nright=3,type=1]
\definebreakpoint [compound] [/] [nleft=3,nright=3,type=1]
\definebreakpoint [compound] [(] [nleft=3,nright=3,type=2]
\definebreakpoint [compound] [)] [nleft=3,nright=3,type=3]

An illustration of a custom breakpoint of type 5:

\definebreakpoints[test]

\definebreakpoint [test] [?] [type=5,left=L,right=R,middle=M]

\setbreakpoints[test]

\setuppapersize[A7]

\starttext \showframe
xxxx?xxxx?xxxx?xxxx?xxxx?xxxx?xxxx?xxxx\par
\stoptext
