isomer.debugger module

Module: Debugger

Debugger overlord

class CLI(*args)

Bases: isomer.component.ConfigurableComponent

Command Line Interface support

This is disabled by default. To enable the command line interface, use either the Configuration frontend or the iso tool:

iso config enable CLI

__init__(*args)

Check for configuration issues and instantiate a component

cli_help(*args)

configprops = {}

register_event(event)

Registers a new command line interface event hook as command

stdin_read(data)

read Event (on channel stdin) This is the event handler for read events specifically from the stdin channel. This is triggered each time stdin has data that it has read.

class IsomerDebugger(root=None, *args)

Bases: isomer.component.ConfigurableComponent

Handles various debug requests.

__init__(root=None, *args)

Check for configuration issues and instantiate a component

channel = 'isomer-web'

Event to register new command line interface event hooks

__init__(cmd, thing, *args, **kwargs)

An event is a message send to one or more channels. It is eventually dispatched to all components that have handlers for one of the channels and the event type.

All normal arguments and keyword arguments passed to the constructor of an event are passed on to the handler. When declaring a handler, its argument list must therefore match the arguments used for creating the event.

Every event has a name attribute that is used for matching the event with the handlers.

Variables:

• channels –

  an optional attribute that may be set before firing the event. If defined (usually as a class variable), the attribute specifies the channels that the event should be delivered to as a tuple. This overrides the default behavior of sending the event to the firing component’s channel.

  When an event is fired, the value in this attribute is replaced for the instance with the channels that the event is actually sent to. This information may be used e.g. when the event is passed as a parameter to a handler.

• value – this is a circuits.core.values.Value object that holds the results returned by the handlers invoked for the event.
• success – if this optional attribute is set to True, an associated event success (original name with “_success” appended) will automatically be fired when all handlers for the event have been invoked successfully.
• success_channels – the success event is, by default, delivered to same channels as the successfully dispatched event itself. This may be overridden by specifying an alternative list of destinations using this attribute.
• complete – if this optional attribute is set to True, an associated event complete (original name with “_complete” appended) will automatically be fired when all handlers for the event and all events fired by these handlers (recursively) have been invoked successfully.
• complete_channels – the complete event is, by default, delivered to same channels as the initially dispatched event itself. This may be overridden by specifying an alternative list of destinations using this attribute.
