Karabo is the [European XFEL](www.xfel.eu)'s SCADA framework. It is a scientific control system
that supports plugin (device) development in C++ and Python.

You can find an overview of Karabo on [Wikipedia](https://en.wikipedia.org/wiki/Karabo_(software)),
and in [this publication](https://www.tandfonline.com/doi/pdf/10.1080/08940886.2023.2277650).

The Karabo source repository is on [GitHub](https://github.com/European-XFEL/Karabo) and
also contains our [Contributing Guidelines](https://github.com/European-XFEL/Karabo/blob/main/CONTRIBUTING.md).

Additional documentation is available on [ReadTheDocs](https://karabo.readthedocs.io/en/latest/)

# Installation

This package facilitates installation of the various Karabo subpackages.

## Standalone and Full

For the installation of Karabo we recommend a fresh python environment.
If you would like to try Karabo in a standalone fashion on a single machine
it's easiest to just run:

```bash
pip install 'karabo[full]'
```

This will install a complete setup, including all essential service devices.
Note that pre-compiled binaries will be installed for [supported operating systems](https://github.com/European-XFEL/Karabo?tab=readme-ov-file#available-operating-systems). Otherwise pip will attempt to compile the source, which might require additional dependencies to be installed first.
If source compilation fails, we recommend you follow the instructions at https://github.com/European-XFEL/Karabo,
which will result in a self-consistent environment, including a Python interpreter, with
similar functionality to a `karabo[full]` installation.

After installation you should initialize the environment with either

```bash
karabo-activate --init-to PATH --standalone
```

for a standalone system, or 


```bash
karabo-activate --init-to PATH [--backbone] --broker-host amqp://{broker:port} --broker-topic {TOPIC}
```

for headless full installations. The `--backbone` option sets the core services up, and the `--broker-*`
parameters are used to configure the installation according to your AMQP broker setup.


## Other options

Instead of a full installation, only individual core packages of Karabo can be installed:

- `karabo[karathon]` will install the Karathon Python API
- `karabo[cpp]` will install the Karabo C++ API
- `karabo[bound]` will install the Karabo Python bindings to C++
- `karabo[services]` will install service tools, allowing to manage installations with `karabo.daemontools`

Options can be combined, such as `karabo[karathon,services]`, which will result in a Karathon installation
with service tools installed.


## Karabo GUI

If you require the GUI, please install it into a separate Python environment:

```bash
pip install karabo.gui
```

## Starting a Karabo standalone system

If you wish to run Karabo standalone you can do this if you have `podman` or `docker` installed on the system.

First, run

```bash
karabo-activate --init-to $PATH --standalone
```

Then run 

```bash
podman-compose -f $PATH/var/containers/compose.yaml up
```

or (`docker-compose ...`). This will start containerized version of the services a full 
Karabo installation requires:

- A RabbitMQ broker (user: xfel, pw: karabo)
- An Influx database instance for logging (user: infadm, pw: admpwd)
- A Grafana installation with the Influx database as a pre-provisioned source (user: admin, pw: admin)

Note that the Grafana provisioning assumes `karabo` as the broker topic in use. If you've
used `karabo-activate --broker-topic TOPIC` you'll need to edit the data source to refer to
a database of `TOPIC` from inside Grafana.

Additionally, the above setup will use a local `sqlite` database for projects.
You can switch this to ` MySQL` database by providing the following arguments
to `karabo-activate`:

- `--project-db HOST:PORT`
- `--project-db-user USER`
- `--project-db-pw PASSWORD`
- `--project-db-name DATABASE_NAME`

Finally, run

```bash
$PATH/activate
```

followed by 

```bash
karabo-start
```

# Device Development

These packages are not intended to facilitate development of devices for Karabo's C++ API. Please 
create a self-consistent development environment using the instructions at https://github.com/European-XFEL/Karabo.

Development of devices against these packages using the Bound and Karathon Python APIs should be trivially
possibly, as long as the device packages define the correct entrypoints.

For the Karathon API, a line similar to this one should exist in your `pyproject.toml`:

```toml
[project.entry-points."karabo.middlelayer_device"]
PropertyTestMDL = "karabo.middlelayer_devices.property_test:PropertyTestMDL"
```

For the Bound API, a line similar to this one should exist in your `pyproject.toml`.

```toml
[project.entry-points."karabo.bound_device"]
PropertyTest = "karabo.bound_devices.property_test:PropertyTest"
```
