from ve_utils import wrap_dbus_value, unwrap_dbus_value
# vedbus contains three classes:
# VeDbusItemImport -> use this to read data from the dbus, ie import
# VeDbusItemExport -> use this to export data to the dbus (one value)
# VeDbusService -> use that to create a service and export several values to the dbus
# Code for VeDbusItemImport is copied from busitem.py and thereafter modified.
# All projects that used busitem.py need to migrate to this package. And some
# projects used to define there own equivalent of VeDbusItemExport. Better to
# use VeDbusItemExport, or even better the VeDbusService class that does it all for you.
# TODOS
# 1 check for datatypes, it works now, but not sure if all is compliant with
# com.victronenergy.BusItem interface definition. See also the files in
# tests_and_examples. And see 'if type(v) == dbus.Byte:' on line 102. Perhaps
# something similar should also be done in VeDbusBusItemExport?
# 2 Shouldn't VeDbusBusItemExport inherit dbus.service.Object?
# 7 Make hard rules for services exporting data to the D-Bus, in order to make tracking
# changes possible. Does everybody first invalidate its data before leaving the bus?
# And what about before taking one object away from the bus, instead of taking the
# whole service offline?
# They should! And after taking one value away, do we need to know that someone left
# the bus? Or we just keep that value in invalidated for ever? Result is that we can't
# see the difference anymore between an invalidated value and a value that was first on
# the bus and later not anymore. See comments above VeDbusItemImport as well.
# 9 there are probably more todos in the code below.
# Some thoughts with regards to the data types:
#
# Text from: http://dbus.freedesktop.org/doc/dbus-python/doc/tutorial.html#data-types
# ---
# Variants are represented by setting the variant_level keyword argument in the
# constructor of any D-Bus data type to a value greater than 0 (variant_level 1
# means a variant containing some other data type, variant_level 2 means a variant
# containing a variant containing some other data type, and so on). If a non-variant
# is passed as an argument but introspection indicates that a variant is expected,
# it'll automatically be wrapped in a variant.
# ---
#
# Also the different dbus datatypes, such as dbus.Int32, and dbus.UInt32 are a subclass
# of Python int. dbus.String is a subclass of Python standard class unicode, etcetera
#
# So all together that explains why we don't need to explicitly convert back and forth
# between the dbus datatypes and the standard python datatypes. Note that all datatypes
# in python are objects. Even an int is an object.
# The signature of a variant is 'v'.
# Export ourselves as a D-Bus service.

"""
Importing basics:
- If when we power up, the D-Bus service does not exist, or it does exist and the path does not
yet exist, still subscribe to a signal: as soon as it comes online it will send a signal with its
initial value, which VeDbusItemImport will receive and use to update local cache. And, when set,
call the eventCallback.
- If when we power up, save it
- When using get_value, know that there is no difference between services (or object paths) that don't
exist and paths that are invalid (= empty array, see above). Both will return None. In case you do
really want to know ifa path exists or not, use the exists property.
- When a D-Bus service leaves the D-Bus, it will first invalidate all its values, and send signals
with that update, and only then leave the D-Bus. (or do we need to subscribe to the NameOwnerChanged-
signal!?!) To be discussed and make sure. Not really urgent, since all existing code that uses this
class already subscribes to the NameOwnerChanged signal, and subsequently removes instances of this
class.
Read when using this class:
Note that when a service leaves that D-Bus without invalidating all its exported objects first, for
example because it is killed, VeDbusItemImport doesn't have a clue. So when using VeDbusItemImport,
make sure to also subscribe to the NamerOwnerChanged signal on bus-level. Or just use dbusmonitor,
because that takes care of all of that for you.

Snoop on the function, writing everything it's doing to stderr.
This is useful for debugging.
When you decorate a function with `@pysnooper.snoop()`
or wrap a block of code in `with pysnooper.snoop():`, you'll get a log of
every line that ran in the function and a play-by-play of every local
variable that changed.
If stderr is not easily accessible for you, you can redirect the output to
a file::
@pysnooper.snoop('/my/log/file.log')
See values of some expressions that aren't local variables::
@pysnooper.snoop(watch=('foo.bar', 'self.x["whatever"]'))
Expand values to see all their attributes or items of lists/dictionaries:
@pysnooper.snoop(watch_explode=('foo', 'self'))
(see Advanced Usage in the README for more control)
Show snoop lines for functions that your function calls::
@pysnooper.snoop(depth=2)
Start all snoop lines with a prefix, to grep for them easily::
@pysnooper.snoop(prefix='ZZZ ')
On multi-threaded apps identify which thread are snooped in output::
@pysnooper.snoop(thread_info=True)
Customize how values are represented as strings::
@pysnooper.snoop(custom_repr=((type1, custom_repr_func1),
(condition2, custom_repr_func2), ...))
Variables and exceptions get truncated to 100 characters by default. You
can customize that:
@pysnooper.snoop(max_variable_length=200)
You can also use `max_variable_length=None` to never truncate them.
Show timestamps relative to start time rather than wall time::
@pysnooper.snoop(relative_time=True)

# vedbus contains three classes:
# VeDbusItemImport -> use this to read data from the dbus, ie import
# VeDbusItemExport -> use this to export data to the dbus (one value)
# VeDbusService -> use that to create a service and export several values to the dbus
# Code for VeDbusItemImport is copied from busitem.py and thereafter modified.
# All projects that used busitem.py need to migrate to this package. And some
# projects used to define there own equivalent of VeDbusItemExport. Better to
# use VeDbusItemExport, or even better the VeDbusService class that does it all for you.
# TODOS
# 1 check for datatypes, it works now, but not sure if all is compliant with
# com.victronenergy.BusItem interface definition. See also the files in
# tests_and_examples. And see 'if type(v) == dbus.Byte:' on line 102. Perhaps
# something similar should also be done in VeDbusBusItemExport?
# 2 Shouldn't VeDbusBusItemExport inherit dbus.service.Object?
# 7 Make hard rules for services exporting data to the D-Bus, in order to make tracking
# changes possible. Does everybody first invalidate its data before leaving the bus?
# And what about before taking one object away from the bus, instead of taking the
# whole service offline?
# They should! And after taking one value away, do we need to know that someone left
# the bus? Or we just keep that value in invalidated for ever? Result is that we can't
# see the difference anymore between an invalidated value and a value that was first on
# the bus and later not anymore. See comments above VeDbusItemImport as well.
# 9 there are probably more todos in the code below.
# Some thoughts with regards to the data types:
#
# Text from: http://dbus.freedesktop.org/doc/dbus-python/doc/tutorial.html#data-types
# ---
# Variants are represented by setting the variant_level keyword argument in the
# constructor of any D-Bus data type to a value greater than 0 (variant_level 1
# means a variant containing some other data type, variant_level 2 means a variant
# containing a variant containing some other data type, and so on). If a non-variant
# is passed as an argument but introspection indicates that a variant is expected,
# it'll automatically be wrapped in a variant.
# ---
#
# Also the different dbus datatypes, such as dbus.Int32, and dbus.UInt32 are a subclass
# of Python int. dbus.String is a subclass of Python standard class unicode, etcetera
#
# So all together that explains why we don't need to explicitly convert back and forth
# between the dbus datatypes and the standard python datatypes. Note that all datatypes
# in python are objects. Even an int is an object.
# The signature of a variant is 'v'.

Importing basics:
- If when we power up, the D-Bus service does not exist, or it does exist and the path does not
yet exist, still subscribe to a signal: as soon as it comes online it will send a signal with its
initial value, which VeDbusItemImport will receive and use to update local cache. And, when set,
call the eventCallback.
- If when we power up, save it
- When using get_value, know that there is no difference between services (or object paths) that don't
exist and paths that are invalid (= empty array, see above). Both will return None. In case you do
really want to know ifa path exists or not, use the exists property.
- When a D-Bus service leaves the D-Bus, it will first invalidate all its values, and send signals
with that update, and only then leave the D-Bus. (or do we need to subscribe to the NameOwnerChanged-
signal!?!) To be discussed and make sure. Not really urgent, since all existing code that uses this
class already subscribes to the NameOwnerChanged signal, and subsequently removes instances of this
class.
Read when using this class:
Note that when a service leaves that D-Bus without invalidating all its exported objects first, for
example because it is killed, VeDbusItemImport doesn't have a clue. So when using VeDbusItemImport,
make sure to also subscribe to the NamerOwnerChanged signal on bus-level. Or just use dbusmonitor,
because that takes care of all of that for you.
