swi_compatibility.pl -- XPCE Compatibility layer

This layer defines some predicates to enhance portability with SICStus and Quintus Prolog. These systems are no longer supported, but it is probably wise to keep this layer for `just-in-case'.

 auto_call(:Goal)

Autoload Goal and call it. If autoloading is enabled we can simply call the target. Otherwise we autoload the predicate and subsequently call it.

This predicate should be used to open new IDE tools, for example the manual opening the editor, etc.

 callable_predicate(:Head) is semidet

Succeeds if Head can be called without raising an exception for an undefined predicate

 modified_since_last_loaded(Path) is semidet

True is file has been modified since the last time it was loaded.

 pce_error(+Term) is det

 pce_warn(+Term) is det

 pce_info(+Term) is det

Portability layer wrappers around print_message/2.
