Sweep Prolog mode integrates with the Emacs xref API to
facilitate quick access to predicate definitions and references in
Prolog code buffers. This enables the many commands that the
xref interface provides, like M-.
(xref-find-definitions) for jumping to the definition of the
predicate at point. See (emacs)Find Identifiers, for an overview
of the available commands.
Sweep Prolog mode also integrates with Emacs’s imenu, which
provides a simple facility for looking up and jumping to definitions
in the current buffer. To jump to a definition in the current buffer,
type M-x imenu RET (bound by default to M-g i in
Emacs version 29 or later). For information about customizing
imenu, (emacs)Imenu.
You can use the command sweeprolog-xref-project-source-files to
update Sweep’s cross reference data for all Prolog source files in the
current project. To determine the set of source files in the current
project, Sweep consults the functions project-current and
project-files (see (emacs)Projects). When you search for
references to Prolog predicates with M-?
(xref-find-references), Sweep implicitly invokes
sweeprolog-xref-project-source-files to bring you up-to-date
references from across the current project.
