Packs (add-ons) for SWI-Prolog

Below is a list of known packages. Please be aware that packages are not moderated. Installing a pack does not execute code in the pack, but simply loading a library from the pack may execute arbitrary code. More information about packages is available here. You can search for packages from the Prolog command line using pack_list/1. This contacts the pack server for packs that match by name or title. A leading i indicates that the pack is already installed, while p merely indicates that it is known by the server.

?- pack_list(graph).
p callgraph@0.3.4           - Predicate call graph visualisation
i graphml@0.1.0             - Write GraphML files
i gvterm@1.1                - Show Prolog terms using graphviz
p musicbrainz@0.6.3         - Musicbrainz client library
p sindice@0.0.3             - Access to Sindice semantic web search engine

After finding the right pack, the pack and its dependencies can be installed using the pack_install/1 as illustrated below.

?- pack_install(hello).

Clicking the package shows details and allows you to rate and comment the pack.
