param_def = []

This property holds the macro parameter description. It consists of a sequence of parameter information objects. A parameter information object is either:

1. a simple parameter object
2. a parameter repetition object

A simple parameter object is a sequence of:

1. a string representing the parameter name
2. a member of Macro.Type representing the parameter data type
3. a default value for the parameter or None if there is no default value
4. a string with the parameter description

Example:

param_def = ( ('value', Type.Float, None, 'a float parameter' ) )

A parameter repetition object is a sequence of:

1. a string representing the parameter repetition name

2. a sequence of parameter information objects

3. a dictionary representing the parameter repetition semantics or None to use the default parameter repetition semantics. Dictionary keys are:

   • min - integer representing minimum number of repetitions or None for no minimum.
   • max - integer representing maximum number of repetitions or None for no maximum.

   Default parameter repetition semantics is { 'min': 1, 'max' : None } (in other words, “at least one repetition” semantics)

Example:

param_def = (
    ( 'motor_list', ( ( 'motor', Type.Motor, None, 'motor name') ), None, 'List of motors')
)

result_def = []

This property holds the macro result description. It a single parameter information object.

hints = {}

Hints to give a client to perform special tasks. Example: scan macros give hints on the types of hooks they support. A GUI can use this information to allow a scan to have sub-macros executed as hooks.

env = ()

a set of mandatory environment variable names without which your macro cannot run

interactive = False

decide if the macro should be able to receive input from the user [default: False]. A macro which asks input but has this flag set to False will print a warning message each time it is executed

run(*args)

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

Raises:RuntimeError

prepare(*args, **kwargs)

Macro API. Prepare phase. Overwrite as necessary. Default implementation does nothing

on_abort()

Macro API. Hook executed when an abort occurs. Overwrite as necessary. Default implementation does nothing

on_pause()

Macro API. Hook executed when a pause occurs. Overwrite as necessary. Default implementation does nothing

on_stop()

Macro API. Hook executed when a stop occurs. Overwrite as necessary. Default implementation calls on_abort()

checkPoint()

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

pausePoint(timeout=None)

Macro API. Will establish a pause point where called. If an external source as invoked a pause then, when this this method is called, it will be block until the external source calls resume. You may want to call this method if your macro takes a considerable time to execute and you may whish to pause it at some time. Example:

for i in range(10000):
    time.sleep(0.1)
    self.output("At step %d/10000", i)
    self.pausePoint()

Recognized kwargs:

• data_type : [default: Type.String] specific input type. Can also specify a sequence of strings with possible values (use allow_multiple=True to say multiple values can be selected)
• key : [default: no default] variable/label to assign to this input
• unit: [default: no default] units (useful for GUIs)
• timeout : [default: None, meaning wait forever for input]
• default_value : [default: None, meaning no default value] When given, it must be compatible with data_type
• allow_multiple : [default: False] in case data_type is a sequence of values, allow multiple selection
• minimum : [default: None] When given, must be compatible with data_type (useful for GUIs)
• maximum : [default: None] When given, must be compatible with data_type (useful for GUIs)
• step : [default: None] When given, must be compatible with data_type (useful for GUIs)
• decimals : [default: None] When given, must be compatible with data_type (useful for GUIs)

parent_macro

Unofficial Macro API. Alternative to getParentMacro that does not throw StopException in case of a Stop. This should be called only internally by the Executor

description

Unofficial Macro API. Alternative to getDescription() that does not throw StopException in case of a Stop. This should be called only internally by the Executor

isAborted()

Unofficial Macro API.

isStopped()

Unofficial Macro API.

isPaused()

Unofficial Macro API.

classmethod hasResult()

Unofficial Macro API. Returns True if the macro should return a result or False otherwise

Returns:True if the macro should return a result or False otherwise Return type:bool

getResult()

Unofficial Macro API. Returns the macro result object (if any)

Returns:the macro result object or None

setResult(result)

Unofficial Macro API. Sets the result of this macro

Parameters:result – (object) the result for this macro

exec_()

Internal method. Execute macro as an iterator

stop()

Internal method. Activates the stop flag on this macro.

abort()

Internal method. Aborts the macro abruptly.

setProcessingStop(yesno)

Internal method. Activates the processing stop flag on this macro

isProcessingStop()

Internal method. Checks if this macro is processing stop

pause(cb=None)

Internal method. Pauses the macro execution. To be called by the Door running the macro to pause the current macro

resume(cb=None)

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

Hookable class

class Hookable(name='', parent=None, format=None)

getAllowedHookHints()

getHints()

getHooks(hint=None)

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

appendHook(hook_info)

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

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)

interactive = True

macro decorator

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

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())
