Dynarec

Parse transform that automaticaly generates and exports accessors for all records declared within a module.

It generates and exports the following functions:

get_value(field_name, Record) ->
    Record#record_name.field_name.

set_value(field_name, Value, Record) when is_record(Record, record_name) ->
    Record#record_name{field_name = Value}.

records() ->
    [record_name1, record_name2, ...].

fields(record_name) ->
    [field_name1, field_name2, ...].

new_record(record_name) ->
    #record_name{}.

It runs at compile time using following preprocessor directive:

-compile({parse_transform, dynarec}).

All those functions are added to the module that uses the directive. Be aware that dynarec.erl must be compiled before any module that uses it.
