The ECLiPSe compiler does not allow the clauses for static predicates being non-consecutive, i.e. interleaved with clauses for other predicates. The event 134 "procedure clauses are not consecutive" is raised in such a case. This library provides a means to handle such programs. When compiling from a file, it is enough just to load the library before the compilation. It redefines that handler for the event 134 in such a way that the procedures with non-consecutive procedures are recompiled in one chunk after encountering the end of file.
When not compiling from a file, the non-consecutive clauses have to be declared using the directive scattered/1. This declaration has to precede any clauses of the predicate.
:- lib(scattered).
:- scattered p/3, q/1.
Note that this applies to predicates whose clauses are non-consecutive, but
in a single file. Predicates that are spread over multiple files
still have to be declared as dynamic
