tasksync

tasksync is a CLI tool to sync tasks between task trackers offered on an as-is basis. The project is in a relatively crude state and makes several assumptions about the end-user (namely: he or she is comfortable with programming).

tasksync was originally developed for, and has been tested with, task syncing between TaskWarrior and Google Tasks. Other implementations may be supported at a future date.

Pull requests are absolutely welcome on this project, especially if they make the project more user-friendly.

Installation

In the current state of the project, you're encouraged to run out of a virtual environment:

1. git clone https://github.com/burnison/tasksync
2. cd tasksync
3. virtualenv .venv
4. . .venv/bin/activate
5. python setup.py install

And, to use:

1. CLIENT_ID='xyz' CLIENT_SECRET='abc' python tasksync --help

Take care to protect your CLIENT_SECRET.

Configuration

To keep the utmost amount of flexibility, configuration is done through the config.py. This means a certain number of assumptions have been made about the user, specifically that he or she is comfortable with python programming. To configure,

1. As always, be sure you have up-to-date backups of everything in the event anything goes wrong.
2. Copy the provided config.py.example file to config.py.
3. Make whatever necessary changes to config.py (see Rough Design).

Notes about Google

When syncing against Google Tasks, an OAuth token will be required. You can create one using the Google Cloud Console.

Upon first execution, you will be prompted, by Google, to authenticate and grant tasksync permission to access your Google Tasks data. Be sure to check the URL, as tasksync relies on third-party libraries to perform OAuth authentication.

Rough design

Each synchronisation is an execution, provided by config.executions. In the provided example, tw2gt is an example on how you can synchronize Google Tasks with TaskWarrior.

Each execution contains an upstream and downstream source. In the provided example, upstream is Google Tasks, and downstream is TaskWarrior. Each source or sink contains a

• TaskFactory, which knows how to create Task objects from the underlying provider.
• Repository, which understands the wire level definition of a Task.
• Filter, which allows tasks to be excluded from the sync.
• Callback, which allows tasks to be fluffed, changed, rewritten, etc. during the sync.
• a decision whether or not "orphaned" tasks should be deleted. Orphaned tasks are those that have a bidirectional association to a task not present in the other system.

Additional providers can be added by the same mechanism, "simply" by extending the TaskFactory, TaskRepository, and Task classes.

Yep, this project is rough

As noted several times in this readme, enhancements are welcome. One day, I plan to add a CalDAV/TaskDAV provider. One day. That's my top priority.
