---

Part of the eFLIPS/simBA list of projects.

---

This repository contains code to evaluate an eflips/simBA simulation. It provides the eflips.evalpackage, which contains functions to prepare (database -> pandas DataFrame) and visualize (pandas DataFrame -> plotly) simulation results.

It is organized hierarchically as follows:

• eflips.eval.input contains functions to prepare and visualize simulation input data. That means it does not access any data from the Event or Vehicle classes.
• eflips.eval.output contains functions to prepare and visualize simulation output data. That means these functions all access the Event or Vehicle classes.
• within each package, there is a prepare and a visualize module. The prepare module contains functions to prepare the data, the visualize module contains functions to visualize the data. The functions must conform tp a naming convention, in which for the eflips.eval.input.preapre.foo(), there must also exist a eflips.eval.input.visualize.foo() method and vice versa. However, when the exact same data can be visualized in multiple ways, there can also be a eflips.eval.input.visualize.foo_scatter() and a eflips.eval.input.visualize.foo_hist() method.
• the signature of a prepare method is always prepare(identifier(s), session) -> pd.DataFrame, where identifier(s) is a single or tuple of ints identifying a specific database object and session is a sqlalchemy.orm.session.Session object that is used to access the database.
• the signature of a visualize method is always visualize(df: pd.DataFrame, **kwargs) -> plotly.graph_objects.Figure, where df is the DataFrame that is to be visualized and kwargs are additional arguments that can be used to customize the visualization. it does however create a legend (if necessary) and sets axis labels.
• a visualize function does not make assumptions about the size of the viewport and does not set the title of the plot.
• The resulting plots should be in english, with proper names (e.g. "Distance [km]" instead of total_dist) for the values that would be shown to the user.

Documentation

The documentation is generated using sphinx. To generate the documentation, execute the following command in the root directory of the repository:

sphinx-build doc/ doc/_build -W

Development

We utilize the GitHub Flow branching structure. This means that the main branch is always deployable and that all development happens in feature branches. The feature branches are merged into main via pull requests. We utilize the semantic versioning scheme for versioning.

Dependencies are managed using poetry. To install the dependencies, execute the following command in the root directory of the repository:

poetry install

We use black for code formatting. You can use black . to format the code.

We use MyPy for static type checking. You can use mypy --strict --explicit-package-bases eflips/ to run MyPy on the code.

Please make sure that your poetry.lock and pyproject.toml files are consistent before committing. You can use poetry check to check this. This is also checked by pre-commit.

You can use pre-commit to ensure that MyPy, Black, and Poetry are run before committing. To install pre-commit, execute the following command in the root directory of the repository:

We recommend utilizing linters such as PyLint for static code analysis (but not doing everything it says blindly).

Usage Example

In examples an example script can be found that generates a report.
