Welcome to the dibs_cli wiki!
Before running this program, ensure you have Python 3.10 or higher installed on your system. If Python is not already installed, you can download and install it from the official website: Python.org
- Visit the Python Downloads page.
- Choose the version appropriate for your operating system (Windows, macOS, or Linux) and click on the download link.
- Run the installer and follow the installation instructions.
- During the installation process, make sure to check the box that says "Add Python to PATH" or "Add Python to environment variables" to ensure Python is added to your system PATH.
- Once the installation is complete, open a command prompt or terminal and type
python --versionto verify that Python is installed correctly.
You can install dibs_cli using pip. First, make sure you have Python and pip (How to install pip) installed on your system. Then, open a terminal or command prompt and run the following command:
pip install dibs_cliThis will download and install the package dibs_cli and all its dependencies from the Python Package Index (PyPI). While the installation, The Package dibs_cli will automatically install packages dibs_computing_core, dibs_datasource_csv and dibs_data, which are necessary for buildings simulation.
Full documentation of the structure of dibs_computing_core (classes, interfaces and methodes) has been bundled in a PDF document which can be found in this repository. Open PDF document.
To use this package dibs_cli read the Repository README.md
