jid.split(id)

Returns 3 strings, the node, host and resource. The node and/or resource may be nil (in the case of a bare or domain JID). The host will be nil only for invalid JIDs (in which case all returns will also be nil).

jid.prepped_split(id)

Same as jid.split(id), but runs stringprep over the JID before splitting.

jid.prep(id)

Returns the passed JID, after applying the stringprep rules.

jid.bare(id)

Returns the bare JID, that is the JID without any resource (if it had one).

jid.node(id)

Return the node part of a JID. For example, jid.node("user@example.com/abc123") would return "user".

Returns nil if the JID has no node part, is malformed, or is nil.

jid.host(id)

Return the host part of a JID. For example, jid.host("user@example.com/abc123") would return "example.com".

Returns nil if the JID is malformed or nil.

jid.resource(id)

Return the resource part of a JID. For example, jid.resource("user@example.com/abc123") would return "abc123".

Returns nil if the JID has no resource, is malformed, or is nil.
