For more information, see the developer guide of your plugin.


  • Add input files using SinglefileData:

    SinglefileData = DataFactory('core.singlefile')
    inputs['file1'] = SinglefileData(file='/path/to/file1')
    inputs['file2'] = SinglefileData(file='/path/to/file2')
  • Specify command line options via a python dictionary and DiffParameters:

    d = { 'ignore-case': True }
    DiffParameters = DataFactory('diff')
    inputs['parameters'] = DiffParameters(dict=d)
  • DiffParameters dictionaries are validated using voluptuous. Find out about supported options:

    DiffParameters = DataFactory('diff')


pip install aiida-diff
verdi quicksetup  # better to set up a new profile
verdi plugin list aiida.calculations  # should now show your calclulation plugins


Here goes a complete example of how to submit a test calculation using this plugin.

A quick demo of how to submit a calculation:

verdi daemon start     # make sure the daemon is running
cd examples
./        # run test calculation
verdi process list -a  # check record of calculation

The plugin also includes verdi commands to inspect its data types:

verdi data diff list
verdi data diff export <PK>


git clone .
cd aiida-diff
pip install --upgrade pip
pip install -e .[pre-commit,testing]  # install extra dependencies
pre-commit install  # install pre-commit hooks
pytest -v  # discover and run all tests

See the developer guide for more information.
