+# 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
+
+```python
+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*")
+Out[3]: 
+['ANS/DG/DCCT-CTRL/State',
+ 'ANS/DG/DCCT-CTRL/Status',
+ 'ANS/DG/DCCT-CTRL/current',
+ 'ANS/DG/DCCT-CTRL/dose',
+ 'ANS/DG/DCCT-CTRL/lifeTime',
+ 'ANS/DG/DCCT-CTRL/lifeTimeErr']
+
+In [4]: # Get data between two dates, this return a pandas.Dataframe object
+   ...: AE.ExtrBetweenDates('ANS/DG/DCCT-CTRL/current', '2021-12-13', '2021-12-13-12:00')

+    Default is None (now).
+
+db: str
+    Which database to look in, 'H' or 'T'.
+
+Exceptions
+----------
+ValueError
+    The attribute is not found in the database.
+
+Returns
+-------
+[date, value] : array
+    date : numpy.ndarray of datetime.datime objects
