- Engines now specify if they support ssml rather than the configuration
- The text client strips out ssml tags
- Engines can modify tags via the `self.modify_tag` method
Several tweaks to CLI behavior
* The "show/hide meter" setting is now persisted
* Fix behavior when scrolled back and logs are rolling off
* Fix potential crash when no logs exist
* Add Ctrl+R to force a refresh (undocumented for now-- help page is getting long and we need an automated system to resize help for smaller screens)
The calulated limit ensures that at least one message will be displayed.
Using a hard-coded constant is ugly, but such are scattered throughout
the script. Untangling those constants has been left for future patch.
* Add wait_for_response method to Websock client
The client handles the basic case when wanting to do a syncronous
request-response action.
The method sets up a handler waits for the response and handles timeout.
The expected format is that the reply message should have the same type as
the original message with ".response" appended.
An method in the Message class has been added to create a standard response for
a message.
* Let the :skills command use wait_for_response
* Minor docstring changes
Fixed typos and refined text
SkillManager now handles the skillmanager.list message and will reply with the
mycroft.skills.list message including a list of the loaded skills.
==== Protocol Notes ====
Added messages:
- skillmanager.list: skill manager send list of skills on messagebus
- mycroft.skills.list message with skill list
* Implement max-line to limit memory usage
The major point of the PR is to limit the memory usage of the CLI by
implementing a maximum log limit. It defaults to 5000.
Other changes:
* Add "--debug" option to support troubleshooting/debugging the CLI itself
* Add support for jumping to the top (Ctrl+T/Ctrl+PgUp) or bottom (Ctrl+B/Ctrl+PgDn) of the logs.
* Remove the "OLDEST" message from the log. It was really no longer necessary since the log navigation issues got straightened out, and it complicated the max log line logic.
Add Python 2/3 compatibility
==== Tech Notes ====
This allows the main bus, skills and cli to be run in both python 2.7 and
3.5+.
Mainly trivial changes
- syntax for exceptions
- logic for importing correct Queue module
- .iteritems -> future.utils.iteritems when accessing dicts key value
pairs
* Allow audio service to be run in python 3
* Make speech client work with python 3
* Importing of Queue version dependent
* Exception syntax corrected
* Creating sound buffer is version dependant
- Adapt context use range from builtins
- Use compatible next() instead of .next() when walking the skill
directory
* Make CLI Python 3 Compatible
- Use compatible BytesIO instead of StringsIO
- Open files as text instead of binary
- Make sure integer divisions are used
* Make messagebus send compatible
* Fix failing travis
Re-add future 0.16.0
* Make string checks compatible
* basestring doesn't exist in python 3 so it's imported from the "past"
* Fix latest compatibility issues in speech client
- handle urllib
- handle encoding before calling md5
* Make Api.build_json() python 2/3 compatible
The mapping from a VT100 key to NCURSES PgUp/PgDn was inverted,
resulting in different behavior for a keyboard and monitor plugged
in to the Pi than when SSH'ed in to the unit.
Several more tweaks for the CLI:
* Ctrl+Left and Ctrl+Right are now available to cycle through previous
entries, just like Ctrl+P and Ctrl+N
* Added ":clear log" command
The functionality of the PgUp and PgDn buttons was inverted in previous
commit.
Also added support for a ":keycode show" to assist in debugging things like
this, plus dropped support the "555" and "500" support which aren't obvious
why they were implemented in the first place. If users encounter problems
under different terminal emulators or whatever, we can use ":keycode show"
to track it down.
Finally, made the inital refresh occur in 1s to clean up any screen
corruption created by messages put out from import of packages at startup.
Several minor changes to the CLI:
* Placed lock on screen refresh from a new log message
* Slowed frequency of mic updates to limit opportunity for screen corruption.
Still happening occasionally, which is vexing.
* Up/Down arrow now scroll logs by a single line
* Ctrl+P/Ctrl+N (Previous/Next) now scroll through the command history
* Ensured that the "Oldest" line is always the first in the log
Several refinements:
* Remove the "What time is it" preloaded example
* Page up/down now moves by 1/2 the # visible log lines instead of always 10 lines
* Reduce the frequency of full-screen redraws to 10 secs instead of 5 (because less needed with the corruption fix)
* Add the version of mycroft-core in the upper-right corner
* FIX: screen redraw now uses a lock, preventing corruption from drawing simultaneously from multiple threads
This cleans up the amount of noise in the logs:
* Removed logging of the serial port raw read/writes.
* Removed the "Setting active skill" log in display_manager.py
* Corrected typo "dispaly"
* Added default CLI filter for mouth.display and mouth.icon messages
* Fixed bug when adding new filters
This commit officially switches the mycroft-core repository from
GPLv3.0 licensing to Apache 2.0. All dependencies on GPL'ed code
have been removed and we have contacted all previous contributors
with still-existing code in the repository to agree to this change.
Going forward, all contributors will sign a Contributor License
Agreement (CLA) by visiting https://mycroft.ai/cla, then they will
be included in the Mycroft Project's overall Contributor list,
found at: https://github.com/MycroftAI/contributors. This cleanly
protects the project, the contributor and all who use the technology
to build upon.
Futher discussion can be found at this blog post:
https://mycroft.ai/blog/right-license/
This commit also removes all __author__="" from the code. These
lines are painful to maintain and the etiquette surrounding their
maintainence is unclear. Do you remove a name from the list if the
last line of code the wrote gets replaced? Etc. Now all
contributors are publicly acknowledged in the aforementioned repo,
and actual authorship is maintained by Github in a much more
effective and elegant way!
Finally, a few references to "Mycroft AI" were changed to the correct
legal entity name "Mycroft AI Inc."
==== Fixed Issues ====
#403 Update License.md and file headers to Apache 2.0
#400 Update LICENSE.md
==== Documentation Notes ====
Deprecated the ScheduledSkill and ScheduledCRUDSkill classes.
These capabilities have been superceded by the more flexible MycroftSkill
class methods schedule_event(), schedule_repeating_event(), update_event(),
and cancel_event().
This extends the Command Line Interpreter with two new features:
* Add command
:find 'string'
Only show log lines that match the given string, including
newly incoming log lines. Hit Ctrl+X to end the search.
Ctrl+F works as a shortcut.
* Add command
:history #
Change the change history height to # lines. This setting
stays across sessions.
Several changes to CLI behavior, all minor:
* Inverted the behavior or PgUp/PgDn. I think it was just wrong
* Added "oldest" and "newest" indicators to the log listing to
simplify finding your way inside the logs
* Added support for _not_ scrolling when in the middle of the log
output. It will now only auto-scroll when already at the front
of the log so you keep seeing new messages automatically.
* Added a heading for the mic output level
* Limited the mic output level to just the size of the bottom
area (previously it was proportional to the screen height)
* FIX: Changed the default filter string for viseme
* FIX: The saving of settings was broken
* Ran autopep8 which added a few bits of whitespace here and there
* Added log filtering commands to the CLI. So you can do things within the CLI like:
:filter DEBUG (filters out any lines containing "DEBUG")
:filter remove DEBUG (stop filtering "DEBUG")
:filter "not this" (filters out any log lines containing "not this")
:filter list (displays active filters)
:filter clear (removes all filters)
* Added a ~/.mycroft-cli.conf configuration file. It currently contains the last-used filters.
* The mycroft.sh scripts were firing up the "fancy" CLI in the background and logging it constantly. This resulted in huge log files because of the constantly updated microphone level indicator.
* The chat history section now wraps long text strings
* Redesigned the section title to combine the header and underscore lines into a single line to save screen space
* Recolored several screen elements to make more sense. The query and the chat history now retain the cyan color, etc.
* The screen fully refreshes periodically, cleaning up garbage that might have accumulated from outside text being written to the terminal
* The mic meter no longer wraps around the screen when level numbers are too long
Main CLI enhancements:
* Microphone meter
* Long log line left/right scrolling
* Eliminated flicker
* VT100 ESC key code support (used by some terms)
In addition, to achieve the meter it was necessary to implement a mechanism for local Inter Process Communication (IPC). This is achieved using the file-system. By default a folder structure is created under /tmp/mycroft/ipc, but it can be directed to somewhere else by setting the config value in mycroft.conf:
"ipc_path" : "/path/to/somewhere"
In the future, Mark 1 and Picroft will get RAM disks to avoid burning out the SD card. This is also a very fast communication mechanism. This is all hidden under util.get_ipc_directory()
Further, the named signal mechanism was changed to use the IPC folder. The signal can have a lifetime now (not just one shot).
* Added "--simple" mode, to get the old cli behavior
* Rewrote to not use tail (works better with multiple log files)
* Added Ctrl+PgUp/Dn support for scrolling back in logs
* Added filtering
* Refined look and log coloring
* Added :help screen
* Added support for terminal resizing
* Uses curses
* Displays a "chat history" with requests and responses
* Shows filtered logs from mycroft-skills.log, mycroft-voice.log
* Start of framework for special ":" commands (for log searching, etc)
* "Input:" doesn't get intermingled with the output (usually -- long pauses can still cause it to happen)
* "Output:" is now displayed
* Ctrl+C is handled gracefully
- Initialize tts ws and enclosure at the main process
Note:
- This is a minimal change to fix the problem.
- The ultimate goal is to have a totally isolated TTS process which requires its own main and ws initialization to be developed soon.
The 1980s birthed a new form of interaction between computers and users. For the first time computers became capable of understanding the most basic form of human communication - pointing and grunting. The mouse and the GUI revolutionized computing and made computers accessible to the masses.
We have now entered a third era. We are rapidly approaching a time when computer systems will understand human language and respond using the most natural form of human communication – speech.
This is an important development. Some might even call it revolutionary.
Despite its importance, however, the technologies that will underpin this new method of interaction are the property of major tech firms who don't necessarily have the public's best interests at heart.
Not anymore.
Meet Mycroft – the worlds first open source natural language platform. Mycroft understands human language and responds with speech. It is being designed to run on anything from a phone to an automobile and will change the way we interact with open source technologies in profound ways.
Our goal here at Mycroft is to improve this technology to the point that when you interact with the software it is impossible to tell if you are talking to a human or a machine.
This initial release of the Mycroft software represents a significant effort by the Mycroft community to give the open source world access to this important technology. We are all hoping that the software will be useful to the public and will help to usher in a new era of human machine interaction.
Our community welcomes everyone to use Mycroft, improve the software and contribute back to the project. With your help and support we can truly make Mycroft an AI for everyone.
