4 The Cross-Reference Tool

4.1 The Cross-Reference Tool (exref)

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:
