Remote controlling#

DataLab may be controlled remotely using the XML-RPC protocol which is natively supported by Python (and many other languages). Remote controlling allows to access DataLab main features from a separate process.

Note

If you are looking for a lighweight alternative solution to remote control DataLab (i.e. without having to install the whole DataLab package and its dependencies on your environment), please have a look at the DataLab Simple Client package (pip install cdlclient).

From an IDE#

DataLab may be controlled remotely from an IDE (e.g. Spyder or any other IDE, or even a Jupyter Notebook) that runs a Python script. It allows to connect to a running DataLab instance, adds a signal and an image, and then runs calculations. This feature is exposed by the RemoteProxy class that is provided in module cdl.proxy.

From a third-party application#

DataLab may also be controlled remotely from a third-party application, for the same purpose.

If the third-party application is written in Python 3, it may directly use the RemoteProxy class as mentioned above. From another language, it is also achievable, but it requires to implement a XML-RPC client in this language using the same methods of proxy server as in the RemoteProxy class.

Data (signals and images) may also be exchanged between DataLab and the remote client application, in both directions.

The remote client application may be written in any language that supports XML-RPC. For example, it is possible to write a remote client application in Python, Java, C++, C#, etc. The remote client application may be a graphical application or a command line application.

The remote client application may be run on the same computer as DataLab or on a different computer. In the latter case, the remote client application must know the IP address of the computer running DataLab.

The remote client application may be run before or after DataLab. In the latter case, the remote client application must try to connect to DataLab until it succeeds.

Supported features#

Supported features are the following:

Switch to signal or image panel

Remove all signals and images

Save current session to a HDF5 file

Open HDF5 files into current session

Browse HDF5 file

Open a signal or an image from file

Add a signal

Add an image

Get object list

Run calculation with parameters

Note

The signal and image objects are described on this section: Internal data model.

Some examples are provided to help implementing such a communication between your application and DataLab:

See module: cdl.tests.remoteclient_app

See module: cdl.tests.remoteclient_unit

../../_images/remote_control_test.png — Screenshot of remote client application test (`cdl.tests.remoteclient_app`)#

Examples#

When using Python 3, you may directly use the RemoteProxy class as in examples cited above or below.

Here is an example in Python 3 of a script that connects to a running DataLab instance, adds a signal and an image, and then runs calculations (the cell structure of the script make it convenient to be used in Spyder IDE):
