Development¶
This plugin uses poetry, typer and black.
The general instructions for development are:
- Fork the code repository
- Clone your fork locally
- Install poetry
- Install the plugin dependencies into a new virtual env with
cd qgis_geonode
poetry install
- Work on a feature/bug on a new branch
- When ready, submit a PR for your code to be reviewed and merged
pluginadmin¶
This plugin comes with a pluginadmin.py
python module which provides a CLI with commands useful for development.
It is used to perform all operations related to the plugin:
- Install the plugin to your local QGIS user profile
- Ensure your virtual env has access to the QGIS Python bindings
- Build a zip of the plugin
- etc.
It is run inside the virtual environment created by poetry. As such it must be invoked like this:
# get an overview of existing commands
poetry run python pluginadmin.py --help
Install plugin into your local QGIS python plugins directory¶
When developing, in order to try out the plugin locally you need to
call poetry run python pluginadmin.py install
command. This command will copy all files into your
local QGIS python plugins directory. Upon making changes to the code you
will need to call this installation command again and potentially also restart QGIS.
Note
Restarting QGIS is necessary because this plugin adds an additional data source provider to QGIS and there is currently no way to reload the available providers without restarting QGIS.
poetry run python pluginadmin.py install
Running tests¶
Tests are made with pytest and pytest-qt. In order to be able to run the tests, the Python virtual environment needs to have the QGIS Python bindings available. This can be achieved by running:
Note
If your QGIS is in a non-standard location, you can set these env variables before running the command:
- `PYQT5_DIR_PATH` - location of PyQt5. Defaults to `/usr/lib/python3/dist-packages/PyQt5`
- `SIP_DIR_PATH` - Location of the SIP package. Defaults to `/usr/lib/python3/dist-packages`
- `QGIS_PYTHON_DIR_PATH` - Location of the QGIS Python bindings. Defaults to `/usr/lib/python3/dist-packages/qgis`
poetry run python pluginadmin.py install-qgis-into-venv
Installing QGIS Python bindings into the Python virtual environment only needs to be done once.
Finally, run tests with:
poetry run pytest
Contributing¶
We welcome contributions from everybody but ask that the following process be adhered to:
-
Find (or open) the issue that describes the problem that you want to help solving. Make a mention in the issue that you are working on a solution
-
Fork this repo and work on a solution to the problem. Remember to add passing automated tests to attest that the problem has been fixed
-
Run your code through the black formatter before submitting your PR. Otherwise the CI pipeline may fail, and we will request that you fix it before merging. This is how we run black in our CI pipeline:
poetry run black src/qgis_geonode
Releasing new versions¶
This plugin uses an automated release process that is based upon github actions. New versions shall be released under the semantic versioning contract.
In order to have a new version of the plugin release:
-
Be sure to have updated the
CHANGELOG.md
-
Be sure to have updated the version on the
pyproject.toml
file. You can either manually modify thetool.poetry.version
key, or you can run thepoetry version {version specifier}
command -
Create a new git annotated tag and push it to the repository. The tag name must follow the
v{major}.{minor}.{patch}
convention, for example:
git tag -a -m 'version 0.3.2' v0.3.2
git push origin v0.3.2
- Github actions will take it from there. The new release shall appear in the custom QGIS plugin repo shortly
