PR #2879 updated the websocket-client and changed function
signatures to account for API changes in that package. These
were falsely changed as the GUI bus does not use the
websocket-client.
Consistency would be good however modifying the protocols
would require significant work. For now we have two slightly
different bus interfaces.
* Upgrade websocket-client to 1.2.1
core equivalent of https://github.com/MycroftAI/mycroft-messagebus-client/pull/21
There was an incompability with the latest websocket-client and the
messagebus which needed fixing for Linux distro compatibility. Since
messagebus-client was going to depend on websocket-client 1.2.1, let's
do the same in core
* Bump message bus client and tornado versions
New version of the messagebus-client released.
Upgraded Tornado to match new function signature.
* Revert removal of websocket-client
It is still used in the `mycroft.client.text.gui_server`
Should investigate removal of this so that websocket client versions do not need to be
kept in sync between mycroft-core and mycroft-messagebus-client.

Switch to new standard method to connect to bus client
Ensure exceptions during .run() are raised to the Enclosure service
Add missing .stop() method to base Enclosure Class
Shift call of .stop() to after exit signal
Major refactoring of the skills startup sequence
- Restructure to a less nested structure
- Remove usage of globals by wrapping a lot of state variables into a class this allows for things like caching a negative pairing status throughout the startup process
Message bus config loading is now shared by service and client.
messagebus.client.ws file is still available in case skills are using it. It is a backport that inherits from the new MessageBusClient class. Adds depreciation warning.
* Catch the new system.gui.user.interaction
This will in turn trigger the gui.page_interaction similar to the page flip but page_number will be None
* Fix issue when adding pages
Seems like appending would fail at times
* Add lock around namespace modifications
* Improve argument description for override_idle
* Add the SkillGUI method send_event()
Sends raw mycroft.events.triggered messages to the gui for the skills namespace.
Example usage:
self.gui.send_event('event_name' {'param1': 12, 'param2': 'abc'})
* Add remove page methods
* Implement SkillGUI.clear()
The method will now remove the namespace entirely from the gui.
This adds the message gui.clear.namespace
* Remove debug prints from SkillGUI
* Correcting docstring
* More docstring changes
* Remove whitespace added by Github webUI
* Add communication from GUI to skills
- "set" events from Qt will set/update a variable in the skills .gui member
- It's possible to add general event handlers using self.gui.register_handler()
- Moved registration of skill_id to just after skill init
* Ensure that simultaneously writes doesn't occur
Wrap WebSocketHandler.write_message() with a lock in an attempt to handle "buffererror: existing exports of data: object cannot be re-sized."
* Add better logging to help debug disconnect issue
* Allow overriding the idle page
SkillGUI.show_page() and SkillGUI.show_pages() now takes an optional
override_idle parameter. This is used as a hint by the mark-2 skill
and if possible the idle screen will not be shown.
* Improve debugging using Logger
* Raise exception when sending a non-existing gui page
* Restore running state to new connections
When a GUI is connected data and running namespaces are synchronised and
shown.
This refactors the code quite a bit moving the GUI state from the GUIConnection
object to the Enclosure.
The GUIConnection object does the handles the sync in the on_connection_open()
method.
* Add gui.page_interaction message
Currently triggered on page change on the display.
* Handle message when gui changes sessionData
* Check if socket exists on gui before sending data
* Increase port on each failure and retry
* Try to improve stability
- Remove sync_active
- Update the way variables are sent to the gui
* Do not show full path for pages
The cli now shows the basename of the current page to make it easier to
determine if the correct page is displayed.
* Make elements in loaded list named tuples
This makes the intent of the code a bit cleaner.
Several additions to the GUI protocol support
These changes allow switching between pages successfully with the current
mycroft-gui widget:
* Optimized commands to handle the active skill list
* MycroftSkill.gui.show_pages(list, idx) allows multiple-pages to be displayed
at a time starting with the given index visible.
* Merge SkillGUI.show_page with show_pages
This limits code duplication and makes things a bit more maintainable.
* Do not reload on changed .qmlc files
* Make EnclosureGeneric derive from Enclosure
* Update show function to match mycroft-gui-app
- adds internal representation of all loaded skills
- uses new commands to switch between pages and namespaces
* Add Extra debug output in enclosure
- Log if starting websocket fails
- Log the sending of page info in more detail
* Update GUI Debug client in CLI
- The CLI GUI now handles the new messages for switching pages
- Handle different data types better by using format instead of string concatenation
* Disable syncing code.
The sync code at startup outdated and needs to be reworked. Disabling it for now
to allow better interaction.
* Minor cleanups
- do not inherit from object
- use format instead of string concatenations
- remove duplicated self.loaded
- correct private member access
* Refactor GUIConnection.show()
Move the actions into separate methods for better overview of the logic
* Flipped "valid_file" to become "ignored_file"
is kept in order, but old namespaces/skills are never culled.
* The active namespace list is synced on a GUIConnection level
* QML display requests now are sent as a list instead of a single entry, i.e.
with "gui_urls" instead of "gui_url". Currently a skill can only send a single
QML, however.
* Change CLI GUI client to handle "gui_urls" instead of "gui_url"
Further fleshing out of the GUI mechanisms
* Support for data and page from Mycroft -> GUIConnection
* Add a 'reconnecting' event for the messagebus
* Add MycroftSkill.show_url()
* Plumb MycroftSkill.gui into the messagebus
* Implement MycroftSkill.gui dictionary
CLI extensions for the GUI:
* Can now act as a simple GUIConnection
* Minor revamp of messagebus connection, provides kinder handling when
messagebus isn't found or ready.
* BUGFIX: An empty filter would filter ALL messages
* BUGFIX: Input wider than the screen would cause a crash
* BUGFIX: "filter" or "find" with no param would filer "filter" or find "find"
Still very much a work in progress.
For understand and testing, here is the sequence:
STEP 1: GUI announces itself
* Connect to the main Mycroft messagebus
* Send: "mycroft.gui.connected" with data { "gui_id": XXX } where XXX is a uniq ID (uuid)
STEP 2: Mycroft creates GUI socket
* Mycroft extracts the gui_id
* Mycroft prepares a socket and announces its availability on the Mycroft messagebus with:
self.bus.emit(Message("mycroft.gui.port",
{"port": self.GUIs[gui_id].port,
"gui_id": gui_id}))
STEP 3: GUI connects
In python, a very minimal test socket handler on the GUI side would look like this
from websocket import create_connection
port = 18181 (from the message above)
ws = create_connection("ws://0.0.0.0:"+port+"/gui")
ws.send("Hello, World")
print("Sent")
print("Receiving...")
result = ws.recv()
print("Received '%s'" % result)
ws.close()
Enclosures
* Create a mechanism to instantiate unique Enclosure classes, depending on the platform found in the SYSTEM mycroft.conf
* Implement a generic Enclosure, which support the new GUI protocol
* Implement a Mark 1 Enclosure (expects the serial connection to an Arduino)
* Implement the start of a Mark II enclosure
* Implement a generic enclosure (no screen)
* Implement the GUI announcement and protocol basics
MycroftSkill
* Implement the basis of the GUI-controlling interfaces. Namely:
- MycroftSkill.show_text()
- MycroftSkill.show_image()
- MycroftSkill.show_html()
- MycroftSkill.show_page()
- MycroftSkill.gui to set values for page displays.
Configuration
* Add "gui_websocket" to the mycroft.config.py
