7. The Abstract Format

7 The Abstract Format

This section describes the standard representation of parse trees for Erlang programs as Erlang terms. This representation is known as the abstract format. Functions dealing with such parse trees are compile:forms/1,2 and functions in the following modules:

• epp(3)
• erl_eval(3)
• erl_lint(3)
• erl_parse(3)
• erl_pp(3)
• io(3)

The functions are also used as input and output for parse transforms, see the compile(3) module.

We use the function Rep to denote the mapping from an Erlang source construct C登录查看完整内容
