%%% @doc Parse transform for generating record access functions.
%%% <p>This parse transform can be used to reduce compile-time
%%% dependencies in large systems.</p>
%%% <p>In the old days, before records, Erlang programmers often wrote
%%% access functions for tuple data. This was tedious and error-prone.
%%% The record syntax made this easier, but since records were implemented
%%% fully in the pre-processor, a nasty compile-time dependency was
%%% introduced.</p>
%%% <p>This module automates the generation of access functions for
%%% records. While this method cannot fully replace the utility of
%%% pattern matching, it does allow a fair bit of functionality on
%%% records without the need for compile-time dependencies.</p>
%%% <p>Whenever record definitions need to be exported from a module,
%%% inserting a compiler attribute,
%%% <code>export_records([RecName|...])</code> causes this transform
%%% to lay out access functions for the exported records:</p>
%%%
%%% <pre>
%%% -module(foo)
%%% -compile({parse_transform, dia_exprecs}).
%%%
%%% -record(a, {a, b, c}).
%%% -export_records([a]).
%%% -export(['#info-'/1, '#info-'/2,
%%% '#get-'/2, '#set-'/2,
%%% '#new-a'/0, '#new-a'/1,
%%% '#get-a'/2, '#set-a'/2,
%%% '#info-a'/1]).
%%%
%%% '#info-'(Rec) -&gt;
%%% '#info-'(Rec, fields).
%%%
%%% '#info-'(a, Info) -&gt;
%%% '#info-a'(Info).
%%%
%%% '#new-a'() -&gt; #a{}.
%%% '#new-a'(Vals) -&gt; '#set-a'(Vals, #a{}).
%%%
%%% '#get-'(Attrs, Rec) when is_record(Rec, a) -&gt;
%%% '#get-a'(Attrs, Rec).
%%%
%%% '#get-a'(Attrs, R) when is_list(Attrs) -&gt;
%%% ['#get-a'(A, R) || A &lt;- Attrs];
%%% '#get-a'(a, R) -&gt; R#a.a;
%%% '#get-a'(b, R) -&gt; R#a.b;
%%% '#get-a'(c, R) -&gt; R#a.c.
