This project is a reference implementation of OpenPulse. Specifically, the parser passes the body of cal and defcal written in OpenPulse. It reuses the classical types and statements from openqasm3.

To install dependencies, change to source/openpulse directory and run:

python -m pip install -r requirements.txt -r requirements-dev.txt

To reuse classic statements/types, OpenPulse grammar imports OpenQASM grammar. When we update the OpenPulse grammar, we also need to copy the latest OpenQASM grammar from https://github.com/openqasm/openqasm/tree/main/source/grammar into the source/grammar directory.

Now build the openpulse grammar. Change to the source/grammar directory and run:

antlr4 -o ../openpulse/openpulse/antlr -Dlanguage=Python3 -visitor openpulseLexer.g4 openpulseParser.g4

Finally, you can change to the source/openpulse directory and run:

pytest .
