The official interpreter for Data Preprocessing Language (DPL). DPL is a domain-specific language for preprocessing of tabular data. DPL has a built-in table type to represent tabular data and has unique syntax for filtering data along with special union and intersection operators. The syntax of DPL is similar to Python since this is a language that is already popular within this domain.

Language documentation and program examples can be found under the docs/ folder.
