`BulletinBoard` is an object strage for `ArrayObject` for debugging and data taking purposes.
For more details, see [`BulletinBoard`](https://github.com/YShoji-HEP/BulletinBoard).
## Caution
* Clients do not check whether the operation is successful or not to improve performance. Check the log of the server for the errors.
* The data is not encrypted. Please do not send any confidential data over the network.
* This crate is under development and is subject to change in specification. (Compatibility across `BulletinBoard` and `dbgbb` is ensured for the most minor version numbers.)
## Install
The package can be installed via [`pip`](https://pypi.org/project/bulletin-board-client/) as
```bash
pip install bulletin-board-client
```
## Example
To post and read the bulletins,
```python
import bulletin_board_client as bbclient
bbclient.set_addr("192.168.0.3:7578")
bbclient.post("test", "tag", [1,2,3])
bbclient.read("test")
```
## Compilation
Instead of installing via pip, you can compile the source yourself.
This crate depends on python packages of `numpy` and `maturin`.
First, you need to clone the repository:
```bash
cargo clone bulletin-board-python
# OR
git clone https://github.com/YShoji-HEP/BulletinBoard.git
```
Then, go to `bulletin-board-python` directory and run
```bash
maturin develop -r
```
