Reimplement projects name without using `task summary`

Hi! It's me again. This time the application panics.

The good news is that I've narrowed it down to a single task, thanks to divide and conquer. My guess is the acute accent in "Lógica" in the project name. If I remove the accent, taskwarrior-tui works again. I've attached data.zip with good.data and bad.data, both containing the same task, but bad.data has "CNC.Lógica" as the project name and good.data has "CNC.Logica" as its project name: data.zip

The following stacktrace is produced:

$ taskwarrior-tui --version
taskwarrior-tui 0.14.8

$ RUST_BACKTRACE=full taskwarrior-tui
Backtrace (most recent call first):
  File "<unknown>", line 0, in __libc_start_main

The application panicked (crashed).
  called `Result::unwrap()` on an `Err` value: ParseIntError { kind: Empty }
in src/pane/project.rs, line 144
thread: main

Taskwarrior behaves normally:

$ task --version
2.6.1

$ task next

ID Age   Project    Tag   Description              Urg
 1 10w   CNC.Lógica T cnc Implementar el algoritmo 2.29

1 task

It happens on version 0.14.6 from the Arch repo and the git version 0.14.8. The OS is Artix Linux.

I also have a crash, although just in the previous line :)

Can you both share the output of task summary?

edit: fyi, I had this problem with v2.5.3 of Taskwarrior. Now I installed v2.6.1 and I have other problems, will do a reboot just in case and see if they persist, and report if it is needed :) .

[kdheepak]

Thanks for sharing the task summary. Yeah, only the latest taskwarrior version is well supported. Older versions of taskwarrior are supported at a “best effort” level. Can you try with the latest version and let me know what happens? And please report any issues!

[Petemir]

Sorry, you can omit my crash then as it was fixed with taskwarrior 2.6.1 :) (but the OP one would still remain). The other issue I had was from a dirty shell environment, solved by a reboot.

(I do have to re-check a context issue though, as switching contexts in taskwarrior-tui shows me the same tasks, but if I change the context via task context X and then show the tasks, they are different.)

[kdheepak]

The context issue might be related to what is going on in #318

[lucaschamorrotuduri]

Dunno if you still need it, but:

$ task --version
2.6.1

I made a new release that should prevent taskwarrior-tui from crashing. You can try it out here: https://github.com/kdheepak/taskwarrior-tui/releases/tag/v0.14.9

However, I think I have to reimplement the projects pane entirely. I think the output of task summary may just be too complicated to parse reliably. So I'll leave this issue open, and rename it appropriately.

To build the project representation, can you use a hash map from project names to a structure recording information for that project, like parent, children, number of tasks, number of subtasks, etc?

[kdheepak]

Yeah that’d be the way to do it! But I’m swamped with work at the moment and can’t devote any time to any significant changes for a little while. Happy to review PRs from anyone though :)
