TextX: A Python tool for Domain-Specific Languages implementation

Abstract TextX is a meta-language and a tool for building Domain-Specific Languages in Python. It’s built on top of the Arpeggio PEG parser and takes away the burden of converting parse trees to abstract representations from language designers. From a single grammar description, textX constructs Arpeggio parser and a meta-model in run-time. The meta-model contains all the information about the language and a set of Python classes inferred from grammar rules. The parser will parse programs/models written in the new language and construct Python object graph a.k.a. the model conforming to the meta-model. The textX tool has support for error reporting, debugging, and meta-model and model visualization. It is used in industrial environments and teaching Domain-Specific Languages course at the Faculty of Technical Sciences in Novi Sad. It is a free and open-source software available at GitHub under the MIT license.
