3 A Cross-Reference Tool

3.1 A Cross-Reference Tool (exref)

Note!

The exref tool has some limitations and is no longer supported. Please consider using the new cross reference tool xref.

exref is an incremental cross reference tool which builds a cross reference graph for selected modules. Information such as module dependencies and usage graphs can be derived from the cross reference graph produced by exref.

A function vertex is represented as: .

{{Mod, Fun, Arity}, {Type, File, Line}}

In this representation, the Type argument equals:

local | exported | {exported, compiler} | {local, compiler} | {Void(), record} 

A call edge is represented as:

{EdgeId, {Mod1, Fun1, Arity1}, {Modd2, Fun2, Arity2}, Line}

The following functions are available for configuring and using the cross reference tool:
