### Install dependencies
```bash
pip install -r requirements.txt
pip install -e .[dev]
```
This will install dependencies for developing, but won't install this project as an library.
To build the wheel files:
```bash
python -m build
```
The wheel file should be located under `dist` folder.
You can use `pip install /path/to/wheel.whl` to install this library.
### Use as a library
Use this URL to add this project as a dependency (NOTE - TODO: update instructions for ForgeJo repo after pulp repo is up & running for python artifacts)
```
git+https://git.cleverthis.com/cleverthis/clevermicro/amq-adapter-python.git@develop#egg=amq_adapter
```
> Hint: use `git config --global credential.helper store` to enable Git credential manager
> so you don't have to re-enter the gitlab credential everytime.
Then:
The library has been published to pulp registry at `https://pkg.cleverthis.io/pypi/clevermicro/amq-adapter-python/`.
Configure the dependency `amq_adapter` with the above registry using
your build tools, then:
```python
from amqp.service import amq_service
# start using the lib
```
#### How to build distributable Wheel archive
install project requirements
`pip install -r requirements.txt`
install distribution archive requirements
`pip install setuptools wheel build`
install project requirements and dev dependencies
`pip install -e .[dev]`
update version in:
`pyproject.toml`
> For dev versions, keep the `-dev` suffix. The pipeline will replace it with a unique timestamp,
> act like maven SNAPSHOT versions.
build the distributable archive (will be located in `./dist` directory)
`python -m build --wheel`
