pySoleilControl
Useful python tools for SOLEIL control system.
The ultimate aim is to provide tools that can be used in a shell prompt, ipython prompt or in python applications (such as GUI).
Under construction, the first brick is a module to retrieve data from the Tango Archiver.
ArchiveExtractor
This module brings some functions to extract data from HDB/TDB.
Usage example, with an ipython prompt
In [1]: import pySoleilControl.ArchiveExtractor as AE
In [2]: # For now, we need manual initialization of the module
...: AE.init()
In [3]: # Looking for an attribute in HDB
...: AE.findattr("ans/dg/*dcct*")
