Taskchampion server/storage integration, general questions

[aktaboot]

Hello,

I have some questions regarding how taskchampion will integrate with taskwarrior

To give some context, I am trying to build a rust application that would synchronize taskwarrior tasks with etebase Calendar+Tasks ( called Etesync).

I was thinking about parsing the exported json or the tw datafiles directly. But I came across the SQLite database and taskchampion integration.

As far as I understand, taskchampion will be responsible for all data storage, so I should be looking to sync with the taskchampion instance instead.

• How should third party app integration work with taskchampion ? I suppose through the sync server ?
• Is this currently doable under the develop branch ?

Any hints on already available information that I may have missed are greatly appreciated

Thanks a lot, love the project

That's great! Early in the development of Taskchampion we actually looked at using etebase as a backend. I think it was a little experimental at the time, so we decided against it.

If I understand what you're suggesting, it's something very different: an app that will coordinate between tasks in Etesync and tasks in Taskwarrior. That's a great idea!

The idea is that integrations with Taskchampion run their own local replica, and share changes to the tasks with replica.sync(). So your interface to Taskchampion would be entirely local, via Rust APIs, and not directly via the sync server (but indirectly through replica.sync()).

This is doable on the develop branch.

I'd encourage you to have a look at taskchampion/docs/src and to run rustdoc for the taskchampion crate. Quite a bit has changed since the last time that crate was published! I'd expect we'll publish again when Taskwarrior is released.

Thanks a lot for the insightful reply, you got it right on what I am trying to achieve!

I will be posting updates at some point when things start working!

Sounds good. Let me know if you have questions!

Haven't made much progress with taskwarrior integration as I figured I'd wait for it the next release and publishing of the taskchampion-lib crate, but my problem might be unrelated

I had some issues while importing the lib crate, I could not use Replica or Storage to access the sqlite database.

for example if I try to use taskchampion_lib::replica::Replica : Struct Replica is private
I am also not sure how I should go about accessing the Storage

My initial thought was I would use SqliteStorage::new(sqlite.db) to access the database, not sure what I am doing wrong

I think you'll want to be using taskchampion -- the taskchampion-lib crate just exposes the C API, which is not especially easy to use from Rust.

It sounds like you have the right idea regarding storage -- just the wrong crate :)
