v0.2.0 is out :)
New features include the ability to set an estimated task duration, support for ongoing and canceled tasks, more powerful search (by tag, due date, task duration, completedness, and of course by name), and the TUI is more robust to external changes.
Thanks :)
It’s as simple as ticking off items (and adding new ones). The categories in Tasks (#tags in Cfait) and child/parent relationships are compatible (it’s all the same iCalendar standard). Tasks doesn’t understand the Blocked-by relationship but the tasks still appear.
You just need a CalDAV server to get going. I use Radicale because it’s lightweight and single-purpose so unlikely to break (and a self-hosted Wireguard VPN because I don’t have a static IP at home). For Android you also need an app to synchronize with the CalDAV server (Tasks doesn’t do it alone), I use DAVx5 (It’s all on F-Droid).
They are generated whenever a new version is released, and available on https://github.com/trougnouf/cfait/releases . I’ve updated the README.
v0.1.9 is out :)
Changelog on https://github.com/trougnouf/cfait/compare/v0.1.7...v0.1.9
My pleasure! :)
Subtasks is the main reason I made this program. I have it in the “Tasks” Android app and I wanted it on desktop too.
The main way it’s implemented is clicking on Link next to a parent task in the GUI (or selecting yank in the TUI), then selecting Child on another task makes it a sub-task of the parent.
I’ve also implemented part of RFC 9253 Support for iCalendar Relationships (Blocked-By logic); after selecting Link/yank on a parent task, there is also the option to select Block on another task and the blocked task appears grayed out and lists the tasks that are blocking it in its description. This is something I haven’t seen in any other CalDAV tasks software and the only thing I would have missed from something like Jira.
And of course one can filter by tags/categories (with AND or OR) so only a (sub-)project is shown (and I’ve added tag aliases, e.g. #refactor_this_worker could autocomplete to #refactor_this_worker, #program_name, #software_development, to make that more convenient).
