Quickstart

Install the package from PyPI:

$ pip install modparc

To parse a Modelica source file “your_modelica_file.mo”:

import modparc
model_definition = modparc.parse_file("your_modelica_file.mo")

To list all the equations in the model_definition instance:

all_equations = model_definition.search('Equation')
for equation in all_equations:
    print(equation.code())  # The code of the equation as string

To get the name of the model loaded:

print(model_definition.name())  # get the name of the stored class
print(model_definition.class_type())  # get the type of the class

Features

• Experimentally parses Modelica Standard Library 3.2.1
• Search element of a certain class

Known Issues

• Handling tokenization of Q-IDENT and comments, which comes first?
• Assertion syntax not defined in Modelica specification
• Default recursion depth is not enough for long vector literals
• Cyclic import is neccessary for the Modelica syntax definition
