While we have made efforts to expand the functionality of this project, it currently has some limitations and does not support all the features of FMI 3.0. We would like to acknowledge and give credit to the original PythonFMU project for their contributions to this work.\n\n### Support:\n\nPlease take a look at the examples to see the supported features.\n\n### Future\n\nIn no particular order, we plan to add support for:\n\n- Support more variable types from FMI3\n- Improve array support\n- Add event mode\n\n### How do I build an FMU from python code?\n\n1. Install `pythonfmu3` package:\n\n```bash\npip install pythonfmu3\n```\n\n2. Create a new class extending the `Fmi3Slave` class declared in the `pythonfmu3.fmi3slave` module (see below for an example).\n3. Run `pythonfmu3 build` to create the fmu.\n\n```\nusage: pythonfmu3 build [-h] -f SCRIPT_FILE [-d DEST] [--doc DOCUMENTATION_FOLDER] [--terminals TERMINALS_FILE] [--no-external-tool]\n                       [--no-variable-step] [--interpolate-inputs] [--only-one-per-process] [--handle-state]\n                       [--serialize-state] [--use-memory-management]\n                       [Project files [Project files ...]]\n\nBuild an FMU from a Python script.\n\npositional arguments:\n  Project files         Additional project files required by the Python script.\n\noptional arguments:\n  -h, --help            show this help message and exit\n  -f SCRIPT_FILE, --file SCRIPT_FILE\n                        Path to the Python script.\n  -d DEST, --dest DEST  Where to save the FMU.\n  --doc DOCUMENTATION_FOLDER\n                        Documentation folder to include in the FMU.\n  --terminals TERMINALS_FILE\n                        Terminals file (terminalsAndIcons.xml) to include in the FMU.\n  --no-external-tool    If given, needsExecutionTool=false\n  --no-variable-step    If given, canHandleVariableCommunicationStepSize=false\n  --interpolate-inputs  If given, canInterpolateInputs=true\n  --only-one-per-process\n                        If given, canBeInstantiatedOnlyOncePerProcess=true\n  --handle-state        If given, canGetAndSetFMUstate=true\n  --serialize-state     If given, canSerializeFMUstate=true\n```\n\n### How do I build an FMU from python code with third-party dependencies?\n\nOften, Python scripts depends on non-builtin libraries like `numpy`, `scipy`, etc.\n_PythonFMU_ does not package a full environment within the FMU.\nHowever, you can package a `requirements.txt` or `environment.yml` file within your FMU following these steps:\n\n1. Install _pythonfmu_ package: `pip install pythonfmu3`\n2. Create a new class extending the `Fmi3Slave` class declared in the `pythonfmu3.fmi3slave` module (see below for an example).\n3. Create a `requirements.txt` file (to use _pip_ manager) and/or a `environment.yml` file (to use _conda_ manager) that defines your dependencies.\n4. Run `pythonfmu3 build -f myscript.py requirements.txt` to create the fmu including the dependencies file.\n\nAnd using `pythonfmu3 deploy`, end users will be able to update their local Python environment. The steps to achieve that:\n\n1. Install _pythonfmu_ package: `pip install pythonfmu3`\n2. Be sure to be in the Python environment to be updated. Then execute `pythonfmu3 deploy -f my.fmu`\n\n```\nusage: pythonfmu3 deploy [-h] -f FMU [-e ENVIRONMENT] [{pip,conda}]\n\nDeploy a Python FMU. The command will look in the `resources` folder for one of the following files:\n`requirements.txt` or `environment.yml`. If you specify a environment file but no package manager, `conda` will be selected for `.yaml` and `.yml` otherwise `pip` will be used. The tool assume the Python environment in which the FMU should be executed is the current one.\n\npositional arguments:\n  {pip,conda}           Python packages manager\n\noptional arguments:\n  -h, --help            show this help message and exit\n  -f FMU, --file FMU    Path to the Python FMU.\n  -e ENVIRONMENT, --env ENVIRONMENT\n                        Requirements or environment file.\n```\n\n### Example:\n\n#### Write the script\n\n```python\n\nfrom pythonfmu3 import Fmi3Causality, Fmi3Slave, Boolean, Int32, Float64, String\n\n\nclass PythonSlave(Fmi3Slave):\n\n    def __init__(self, **kwargs):\n        super().__init__(**kwargs)\n\n        self.author = \"John Doe\"\n        self.description = \"A simple description\"\n\n        self.time = 0.0\n        self.intOut = 1\n        self.realOut = 3.0\n        self.booleanVariable = True\n        self.stringVariable = \"Hello World!\"\n        self.register_variable(Float64(\"time\", causality=Fmi3Causality.independent))\n        self.register_variable(Int32(\"intOut\", causality=Fmi3Causality.output))\n        self.register_variable(Float64(\"realOut\", causality=Fmi3Causality.output))\n        self.register_variable(Boolean(\"booleanVariable\", causality=Fmi3Causality.local))\n        self.register_variable(String(\"stringVariable\", causality=Fmi3Causality.local))\n        \n        # Note:\n        # it is also possible to explicitly define getters and setters as lambdas in case the variable is not backed by a Python field.\n        # self.register_variable(Float64(\"myReal\", causality=Fmi3Causality.output, getter=lambda: self.realOut, setter=lambda v: set_real_out(v))\n\n    def do_step(self, current_time, step_size):\n        return True\n\n```\n\n#### Create the FMU\n\n```\npythonfmu3 build -f pythonslave.py myproject\n```\n\nIn this example a python class named `PythonSlave` that extends `Fmi3Slave` is declared in a file named `pythonslave.py`,\nwhere `myproject` is an optional folder containing additional project files required by the python script.\nProject folders such as this will be recursively copied into the FMU. Multiple project files/folders may be added.\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstephensmith25%2Fpythonfmu3","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fstephensmith25%2Fpythonfmu3","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstephensmith25%2Fpythonfmu3/lists"}
