edinburgh.pl -- Some traditional Edinburgh predicates

This module defines predicates from `traditional Edinburgh Prolog' (Dec10 and C-Prolog) whose functionality has been replaced by (ISO) Standard Prolog.

 display(+Term) is det

 display(+Stream, +Term) is det

Write a term, ignoring operators and special syntax constructs such as brace terms ({a}) and lists ([a,b,c]). Currently does print dicts using the dict notation.

See also

- write_canonical/2. SWI-Prolog's write_canonical/2, however, prints lists using lst notation to reduce incompatibility due to the modified list functor ('[|]' rather than `.`) and reduce memory usage while parsing lists.

 unknown(-Old, +New) is det

Edinburgh Prolog predicate for dealing dealing with undefined procedures

 reconsult(+FileOrList) is det

Load source file(s), wiping the old content first. SWI-Prolog's consult/1 and related predicates always do this.

deprecated

- The Edinburgh Prolog consult/reconsult distinction is no longer used throughout most of the Prolog world.

 debug is det

 nodebug is det

Switch on/off debug mode. Note that nodebug/0 has been defined such that is is not traced itself.

 fileerrors(-Old, +New) is det

Query and change the fileerrors flag. Default it is set to true, causing file operations to raise an exception. Setting it to false activates the old Edinburgh mode of silent failure.

deprecated

- New code should use catch/3 to handle file errors silently

Undocumented predicates

The following predicates are exported, but not or incorrectly documented.
