Macro API reference

Macro class

class Macro(*args, **kwargs)[source]

The Macro base class. All macros should inherit directly or indirectly from this class.

Abort = 0
All = 'All'
BlockFinish = '</BLOCK>'
BlockStart = '<BLOCK>'
Exception = 11
Fault = 8
Finished = 0
Init = 9
Pause = 7
Ready = 0
Running = 10
Stop = 7
abort()[source]

Internal method. Aborts the macro abruptly.

addObj(*args, **kwargs)[source]

Macro API. Adds the given object to the list of controlled objects of this macro. In practice it means that if a stop is executed the stop method of the given object will be called.

Parameters:
  • obj (object) – the object to be controlled
  • priority (int) – wheater or not reserve with priority [default: 0 meaning no priority ]
addObjs(*args, **kwargs)[source]

Macro API. Adds the given objects to the list of controlled objects of this macro. In practice it means that if a stop is executed the stop method of the given object will be called.

Parameters:obj_list (collections.Sequence) – list of objects to be controlled
checkPoint(*args, **kwargs)[source]

Macro API. Empty method that just performs a checkpoint. This can be used to check for the stop. Usually you won’t need to call this method

createExecMacroHook(*args, **kwargs)[source]

Macro API. Creates a hook that executes the macro given as a sequence of strings where the first string is macro name and the following strings the macro parameters

Parameters:
  • par_str_sequence – the macro parameters
  • parent_macro – the parent macro object. If None is given (default) then the parent macro is this macro
Returns:

a ExecMacroHook object (which is a callable object)

createMacro(*args, **kwargs)[source]

self.execMacro('mv', [[motor.getName(), '0']])
self.execMacro('mv', motor.getName(), '0') # backwards compatibility - see note
self.execMacro('ascan', 'th', 0, 100, 10, 1.0)
self.execMacro('mv', [[motor.getName(), 0]])
self.execMacro('mv', motor.getName(), 0) # backwards compatibility - see note
th = self.getObj('th')
self.execMacro('ascan', th, 0, 100, 10, 1.0)
self.execMacro('mv', [[th, 0]])
self.execMacro('mv', th, 0) # backwards compatibility - see note

# a sequence of parameters:
self.execMacro(['ascan', 'th', '0', '100', '10', '1.0')
self.execMacro(['mv', [[motor.getName(), '0']]])
self.execMacro(['mv', motor.getName(), '0']) # backwards compatibility - see note
self.execMacro(('ascan', 'th', 0, 100, 10, 1.0))
self.execMacro(['mv', [[motor.getName(), 0]]])
self.execMacro(['mv', motor.getName(), 0]) # backwards compatibility - see note
th = self.getObj('th')
self.execMacro(['ascan', th, 0, 100, 10, 1.0])
self.execMacro(['mv', [[th, 0]]])
self.execMacro(['mv', th, 0]) # backwards compatibility - see note

reloadMacros(*args, **kwargs)[source]

Macro API. Reloads the modules corresponding to the given macro names.

Raises:MacroServerExceptionList in case the macro(s) are unknown or the reload process is not successfull
Parameters:macro_names (sequence<str>) – a list of macro names
report(*args, **kwargs)[source]

Macro API. Record a log message in the sardana report (if enabled) with default level INFO. The msg is the message format string, and the args are the arguments which are merged into msg using the string formatting operator. (Note that this means that you can use keywords in the format string, together with a single dictionary argument.)

kwargs are the same as logging.Logger.debug() plus an optional level kwargs which has default value INFO

Example:

self.report("this is an official report of macro %s", self.getName())
Parameters:
  • msg (str) – the message to be recorded
  • args – list of arguments
  • kwargs – list of keyword arguments
resetViewOption(*args, **kwargs)[source]
result_def = []
resume(cb=None)[source]

Internal method. Resumes the macro execution. To be called by the Door running the macro to resume the current macro

returnObj(obj)[source]

Removes the given objects to the list of controlled objects of this macro.

Parameters:obj – object to be released from the control
Return type:object
run(*args)[source]

Macro API. Runs the macro. Overwrite MANDATORY! Default implementation raises RuntimeError.

Raises:RuntimeError
runMacro(*args, **kwargs)[source]

Macro API. Runs the macro. This the lower level version of execMacro(). The method only returns after the macro is completed or an exception is thrown. It should be used instead of execMacro when some operation needs to be done between the macro preparation and the macro execution. Example:

macro = self.prepareMacro("mymacro", "myparam")
self.do_my_stuff_with_macro(macro)
self.runMacro(macro)
Parameters:macro_obj – macro object
Returns:macro result
sendRecordData(*args, **kwargs)[source]

Macro API. Sends the given data to the RecordData attribute of the Door

Parameters:data – (sequence) the data to be sent
setData(*args, **kwargs)[source]

Macro API. Sets the data for this macro

Parameters:data (object) – new data to be associated with this macro
setEnv(*args, **kwargs)[source]

Macro API. Sets the environment key to the new value and stores it persistently.

Returns:a tuple with the key and value objects stored
Return type:tuple<str, object>
setLogBlockFinish(*args, **kwargs)[source]

Macro API. Specifies the end of a block of data. Basically it outputs the ‘/BLOCK’ tag

setLogBlockStart(*args, **kwargs)[source]

Macro API. Specifies the begining of a block of data. Basically it outputs the ‘BLOCK’ tag

setProcessingStop(yesno)[source]

Internal method. Activates the processing stop flag on this macro

setResult(result)[source]

Unofficial Macro API. Sets the result of this macro

Parameters:result – (object) the result for this macro
setViewOption(*args, **kwargs)[source]
stack(*args, **kwargs)[source]

Macro API. Logs the stack with level TRACE on the macro logger.

stop()[source]

Internal method. Activates the stop flag on this macro.

trace(*args, **kwargs)[source]

Macro API. Record a trace message in this object’s logger.

Parameters:
  • msg – (str) the message to be recorded
  • args – list of arguments
  • kw – list of keyword arguments
traceback(*args, **kwargs)[source]

Macro API. Logs the traceback with level TRACE on the macro logger.

unsetEnv(*args, **kwargs)[source]

Macro API. Unsets the given environment variable.

Parameters:key (str) – the environment variable name
warning(*args, **kwargs)[source]

Macro API. Record a warning message in this object’s logger. Accepted args and kwargs are the same as logging.Logger.warning(). Example:

self.warning("this is a log message for macro %s", self.getName())
Parameters:
  • msg (str) – the message to be recorded
  • args – list of arguments
  • kwargs – list of keyword arguments

Hookable class

class Hookable(name='', parent=None, format=None)[source]
appendHook(hook_info)[source]

Append a hook according to the hook information

Parameters:hook_info – sequence of two elements, the first one is the hook and its optional parameters/arguments, the second one is the list of hints e.g. hook places
getAllowedHookHints()[source]
getHints()[source]
getHooks(hint=None)[source]

This will return a list of hooks that have the given hint. Two reserved hints are always valid:

  • “_ALL_”: which contains all the hooks
  • “_NOHINTS_”: which contains the hooks that don’t provide any hint
Parameters:hint – (str) a hint. If None is passed, it returns a list of (hook,hints) tuples
Returns:(list) an ordered list of hooks that have the given hint
hooks

Hooks (callables) attached to the macro object together with the hook places (places where they will be called).

Getter:Return all hooks attached to the macro object (including general hooks).
Setter:Set hooks to the object. This may override eventual general hooks. Use appendHook() if the general hooks want to be kept. For backwards compatibility accepts hook in the list<callable> format.
Type:list<tuple> where each tuple has two elements: callable and list<str>

iMacro class

class iMacro(*args, **kwargs)[source]
interactive = True

macro decorator

class macro(param_def=None, result_def=None, env=None, hints=None, interactive=None)[source]

Class designed to decorate a python function to transform it into a macro. Examples:

@macro()
def my_macro1(self):
    self.output("Executing %s", self.getName())

@macro([ ["moveable", Type.Moveable, None, "motor to watch"] ])
def where_moveable(self, moveable):
    self.output("Moveable %s is at %s", moveable.getName(), moveable.getPosition())
