# Watch and view your data in real-time.
This application allow you to watch your data in real-time (using a simple and documented protocol) or view them from files.

This crate make it easy to display the data from third-party applications.

GTK4 must be installed to build this application:
```
sudo apt install libgtk-4-dev
```


(under development)

- Usage examples are available here:

Data can be streamed in real-time through an ipc socket defined in /tmp/dataviewer.ipc.
The ipc is using the same format than files. The only difference is each message/update must be termined by a NULL character.
So, you may very well cat your dataview file in the ipc terminated by a '\0' followed up by updates each terminated by a '\0'.
