Bliss Objects¶
lsobj¶
-
lsobj(): print the list of BLISS objects defined in a session. Can be used with usual jocker characters:*: matches everything?: matches any single character[seq]: matches any character in seq[!seq]: matches any character not in seq
Examples:
TEST_SESSION [2]: lsobj("dio*") # all objects starting by 'dio'
diode diode2 diode3 diode4 diode5 diode6 diode7 diode8 diode9
TEST_SESSION [3]: lsobj("[abc]*") # all objects starting by 'a', 'b' or 'c'
beamstop att1 bad calc_mot1 calc_mot2 custom_axis
TEST_SESSION [6]: lsobj("???") # all objects with 3-lettres names
MG1 MG2 bad s1b s1d s1f s1u
lsconfig¶
lsconfig(): print the list of BLISS objects in config, not only objects declared in current session.
Example:
DEMO [2]: lsconfig()

Data Policy¶
newproposal()newsample()newdataset(): Change the proposal sample and dataset names used to determine the saving path.
For more info about these three functions, see data policy section
Display¶
-
plotselect(): select counter(s) to plot in Flint -
clear(): clear the screen. -
silx_view(): launch Silx View on last scan’s data file. -
pymca(): launch PyMca on last scan’s data file.
Dialogs¶
Some bliss objects can be used with dialogs.
To check if an object has dialogs implemented you can use the menu function.
Using menu() without further arguments will display all objects that has
dialogs implemented.
Using using menu(object) will launch the dialog with his effects. If more than
one dialog exists for the same object you can either pass the dialog name as a string
like menu(lima_simulator, "saving") or just use menu(lima_simulator) and first
you will select between available dialogs and than use the selected one.
Using
TEST_SESSION [2]: menu()
Out [2]: Dialog available for the following objects:
ACTIVE_MG
MG1
MG2
ascan
lima_simulator
test_mg
transfocator_simulator
wago_simulator
...
TEST_SESSION [3]: show(trasfocator_simulator)
.. HERE THE DIALOG DISPLAYS ..
Out [3]: Transfocator transfocator_simulator: # effects of dialog
P0 L1 L2 L3 L4 L5 L6 L7 L8
IN IN OUT IN OUT OUT IN IN IN
TEST_SESSION [4]: show(lima_simulator, "saving")
.. HERE THE DIALOG DISPLAYS ..
Out [4]: # display of return status if present
TEST_SESSION [5]: show(lima_simulator)
.. HERE SUBMENU DIALOG DISPLAYS ..
.. THAN SELECTED DIALOG DISPLAYS ..
Out [5]: # display of return status if present
Wago Interlocks¶
-
interlock_show([wago]*): display interlocks info for given Wagos (for all wagos if no parameter is given). -
interlock_state(): return a tuple containing the actual state of the interlocks.
introspection, doc, logging¶
Logging and Debug¶
-
lslog(): display the list of loggers. -
lsdebug(): display the list of loggers currently in debug mode. -
debugon()/debugoff(): activate/deactivate debug on a BLISS object.
elog_print¶
elog_print() can be used like python’s standard print() to send messages to the logbook.
elog_add¶
The output from a previously execute command can be sent to the logbook
simply using elog_add(num).
When the parameter num is positive it refers to the shell paragraph number.
When the parameter num is negative it refers to the shell paragraph relative
to the current paragraph number.
If no parameter is specify the previous paragraph is sent (corresponds to -1).
Following an example sending to the logbook for three times the same output:
TEST_SESSION [1]: transfocator_simulator
Out [1]: Transfocator transfocator_simulator:
P0 L1 L2 L3 L4 L5 L6 L7 L8
OUT IN IN IN OUT IN OUT IN OUT
TEST_SESSION [2]: elog_add() # adds previous paragraph (-1)
TEST_SESSION [3]: elog_add(1) # can be used with reference to the paragraph number
TEST_SESSION [4]: elog_add(-3) # can be also used with relative negative reference
elog_plot¶
Export the actual curve plot to the logbook.
An optional argument allow to export the dedicated plot displaying a Lima or MCA controller.
TEST_SESSION [2]: elog_plot() # export the default curve plot to the logbook
TEST_SESSION [3]: elog_plot(lima_simulator) # export the plot displaying this Lima device
prdef (print definition)¶
prdef(<function>): Display information about given function : definition file, docstring and source code.
CC4 [17]: prdef(umv)
'umv' is defined in:
/users/blissadm/..../site-packages/bliss/common/standard.py:217
def umv(*args):
"""
Moves given axes to given absolute positions providing updated display of
the motor(s) position(s) while it(they) is(are) moving.
Arguments are interleaved axis and respective absolute target position.
"""
__umove(*args)
bench¶
bench(): context manager to help benchmarking functions.
Example:
DEMO [14]: with bench():
...: time.sleep(1.987654)
Execution time: 1s 987ms 970μs
