🔖 Feature description

In the upcoming Tasks 3.3.0 it will be possible to select:

• either the Tasks emoji format
• or the dataview format

In the dataview's own parsing, it reads both Tasks and dataview formats.

However, in order to simplify the first release of dataview reading, I opted to live with the limitation that the code only reads the user's chosen format.

This feature request is adjust the task-reading code so that it parses all supported formats instead.

✔️ Solution

Adjust the Tasks serialiser code so that it iterates over all formats.

Probably #1505 should be fixed first, as it will make the implementation of this a lot easier.

❓ Alternatives

Use dataview, or use a text editor to convert all your tasks to dataview format.

If a dataview already has a functionality to understand both formats at the same time wouldn't it be just "hippity hoppity this is now my property" kind of PR?

I have no idea what you mean, but dataview does not support recurring tasks.

It would still be great to get support for Tasks emoji signifiers when using Dataview format!
