pce_prolog_xref.pl -- XPCE plugin for library(prolog_xref)
This library facilitates using PceEmacs editors as sources for the
Prolog cross referencer.
prolog:xref_source_identifier(+Object, -Ref)[multifile]- The cross-referencer runs faster if the reference is an
indexable term. Therefore we strip the XPCE @ from the object.
prolog:xref_source_directory(+Source, -Dir)[multifile]- Find the directory of a PceEmacs buffer to resolve relative paths.
prolog:xref_open_source(+Source, -Stream)[multifile]- Open the PceEmacs as a Prolog stream.
