Examples
--------
The easiest way to use BoutRunner is to run a script from the root directory of
the project (i.e. where the `Makefile` and `data` directory are normally
situated. The script can simply call
>>> BoutRunner().run()
and `BoutRunner` takes care of the rest.
A more elaborate example where all the dependency objects are built manually:
Import dependencies
>>> from pathlib import Path
>>> from bout_runners.executor.bout_paths import BoutPaths
>>> from bout_runners.executor.executor import BoutRunExecutor
>>> from bout_runners.database.database_connector import DatabaseConnector
>>> from bout_runners.parameters.default_parameters import DefaultParameters
>>> from bout_runners.parameters.run_parameters import RunParameters
>>> from bout_runners.parameters.final_parameters import FinalParameters
>>> from bout_runners.submitter.local_submitter import LocalSubmitter
>>> from bout_runners.runner.bout_run_setup import BoutRunSetup
>>> from bout_runners.runner.run_graph import RunGraph
>>> from bout_runners.runner.run_group import RunGroup
Create the `bout_paths` object
>>> project_path = Path().joinpath('path', 'to', 'project')
>>> bout_inp_src_dir = Path().joinpath('path', 'to', 'source', 'BOUT.inp')
>>> bout_inp_dst_dir = Path().joinpath('path', 'to', 'destination', 'BOUT.inp')
>>> bout_paths = BoutPaths(project_path=project_path,
... bout_inp_src_dir=bout_inp_src_dir,
... bout_inp_dst_dir=bout_inp_dst_dir)
Create the input objects
>>> default_parameters = DefaultParameters(bout_paths)
>>> run_parameters = RunParameters({'global': {'nout': 0}})
>>> final_parameters = FinalParameters(default_parameters,
... run_parameters)
>>> executor = BoutRunExecutor(
... bout_paths=bout_paths,
... submitter=LocalSubmitter(bout_paths.project_path),
... run_parameters=run_parameters)
>>> db_connector = DatabaseConnector('name_of_database', db_root_path=Path())
>>> bout_run_setup = BoutRunSetup(executor, db_connector, final_parameters)
>>> run_graph = RunGraph()
>>> # The RunGroup can attach pre and post-processors to the run
>>> # See the user manual for more info
>>> _ = RunGroup(run_graph, bout_run_setup, name='my_test_run')
Run the project
>>> runner = BoutRunner(run_graph)
