Environment

The environment is a persistent dictionary which stores experiment-related information. It is accessed though the following functions:

• lsenv(): display the environment

  In [14]: blueskyDESY.lsenv()
                        Name                                                        Value   Type
  -------------------------- ------------------------------------------------------------ ------
                ActiveMntGrp                                                          MG1    str
                         MG1 {'counters': ['eh_c01', 'eh_c02', 'eh_c03'], 'timers': ['eh_   dict
  

• senv( k, v): set key k to value v

  In [15]: blueskyDESY.senv( 'ScanDir', '/tmp')
  ScanDir = '/tmp'
  
  In [16]: blueskyDESY.lsenv()
                        Name                                                        Value   Type
  -------------------------- ------------------------------------------------------------ ------
                ActiveMntGrp                                                          MG1    str
                         MG1 {'counters': ['eh_c01', 'eh_c02', 'eh_c03'], 'timers': ['eh_   dict
                     ScanDir                                                         /tmp    str
  

• usenv( k): deletes the key k from the environment

  In [17]: blueskyDESY.usenv( 'ScanDir')
  delete ScanDir
  
  In [18]: blueskyDESY.lsenv()
                        Name                                                        Value   Type
  -------------------------- ------------------------------------------------------------ ------
                ActiveMntGrp                                                          MG1    str
                         MG1 {'counters': ['eh_c01', 'eh_c02', 'eh_c03'], 'timers': ['eh_   dict
  

• getEnv(): returns the environment

   
  In [1]: blueskyDESY.getEnv()
  Out[1]: PersistEnv({'ActiveMntGrp': 'MG1', 
                      'MG1': {'counters': ['eh_c01', 'eh_c02'], 
                              'timers': ['eh_t01'], 
                               'sampleTime': 0.1}})
  

• setEnv( hsh): delete the elements of the environment then fill the environment with the dictionary supplied

  In [5]: blueskyDESY.setEnv( {'ActiveMntGrp': 'MG1', 'MG1': {'counters': ['eh_c01',
     ...: 'eh_c02', 'eh_c03'], 'timers': ['eh_t01'], 'sampleTime': 0.2}})
