B-OCL is a tool designed to parse and evaluate the OCL constraints designed on BESSER models. It is a python based implementation, that utilises parser and listener generated with the ANTLR4 grammer.
BESSER is a low-modeling low-code open-source platform built on top of our Python-based personal interpretation of a "Universal Modeling Language"
We have tested B-OCL with python 3.9+. We recommend creating a virtual environment using venv <https://docs.python.org/3/tutorial/venv.html>, or
conda <https://docs.conda.io/en/latest/>).
Dependencies
B-OCL depends on BESSER for parsing the OCL constraints and providing a concrete syntax tree (CST) to evaluate. The latest stable version of BESSER is available in the Python Package Index (PyPi) and can be installed using
$ pip install besser
Stable version of B-OCL interpreter can be installed via
$ pip install bocl
To obtain the full code, including examples and tests, you can clone the git repository.
$ git clone https://github.com/BESSER-PEARL/b-ocl-Interpreter
$ cd b-ocl-Interpreter
To install the reqs please run the following commands in virtual environment (recommended)
$ pip install -r requirements.txt
