Build Instructions

Prerequisites

Check out the SGrPython repository, e.g. in SGrPython.

Create and activate virtual environment:

cd SGrPython
python -m venv .venv

# On Linux call this:
source ./.venv/bin/activate

# On Windows call this:
.\.venv\Scripts\Activate.ps1

Make sure you have the specification library SGrSpecificationPythontks4r installed in your virtual environment. See specification for instructions.

Run Tests

You can run tests using pytest while in virtual environment.

It is not necessary to install the package locally, if you only want to run tests.

cd SGrPython/commhandler
pip install -r requirements-dev.txt

pytest

Build and Use Package

Build package and install in virtual environment:

cd SGrPython/commhandler
pip install -e .

You can use the package SGrPythontks4r from within the virtual environment now.

Note: The designated package name sgr-commhandler must not be used until the PyPI administrators have approved a SmartGridready organization account!

Clean Up

Deactivate the virtual environment after use:

cd SGrPython
deactivate
