A The SWI-Prolog library
This chapter documents the SWI-Prolog library. As SWI-Prolog provides auto-loading, there is little difference between library predicates and built-in predicates. Part of the library is therefore documented in the rest of the manual. Library predicates differ from built-in predicates in the following ways:
- User definition of a built-in leads to a permission error, while
using the name of a library predicate is allowed.
- If autoloading is disabled explicitly or because trapping unknown
predicates is disabled (see unknown/2
and
current_prolog_flag/2),
library predicates must be loaded explicitly.
- Using libraries reduces the footprint of applications that don't need them.
The documentation of the library has just started. Material from the standard packages should be moved here, some material from other parts of the manual should be moved too and various libraries are not documented at all.
