Software summary: The software offers structured filters to sort data structures with ease. The filters help in quickly identifying complex data sets by organizing and sorting them based on selected criteria.
Data::Filter is a powerful Perl module that makes filtering data structures with structured filters a breeze. As a developer, I know that the structure of your data set is rarely in a neat format. However, I have designed this module to ensure that recursive filters do not confuse the difference between records, as each record has its unique key.
If your data set is in an array format, a helper function is available to quickly convert it to the required hash reference form. You can use the arrayToHash function that returns a hash reference. Additionally, the filterData subroutine returns a hash reference in the same form as the provided data set (hash reference, rather than array). There is also a utility subroutine called hashToArray available to deal with such circumstances.
To create any meaningful results, you need to understand the format of the filtering array. A filter is in the form of [op, column, value, (value2, value3, ...)]. It could also be more complex, for example, [OP_AND, [(see above)], []] or [OP_AND, [OP_NOT, [OP_EQ, column, value,]], [#...],].
The module is easy to use. You can import it using the "use Data::Filter" statement. Then convert your array into the required hash reference form and create a filter as described above. Finally, pass these to the filterData subroutine, and let it do the rest.
In summary, Data::Filter is an excellent Perl module that simplifies filtering data structures with structured filters. The comprehensive developer comments and easy-to-use subroutines make this module an essential tool for anyone working with complex data sets.
