Issue 1703 timewarrior block

[Mice7R]

Adds a block that displays the time of the current active task in timewarrior.

Closes #1703

[Mice7R]

I can fix the things clippy is complaining about and the typo but what can I do with cspell? timew is the name of the program.

[MaxVerevkin]

timew is the name of the program

Please add it to https://github.com/greshake/i3status-rust/blob/master/cspell.yaml

[MaxVerevkin]

@notramo would you like to test this?

[Mice7R]

This thing got stuck in pending. I've implemented your suggestion and updated the code for the new api.

[Mice7R]

Wait, I've noticed there is an error when "continuing" a task

[Mice7R]

There

Looks like there's 2 small formatting issues (missing ,s)

You can avoid having to use the TimewarriorRAW intermediate stucture like this:

Any maybe this is a stupid question, but as someone who's never used taskwarrior can you have multiple tasks at the same time?

Here's a version without using the RAW intermediate stuct:

Any maybe this is a stupid question, but as someone who's never used taskwarrior can you have multiple tasks at the same time?

Timewarrior and Taskwarrior are 2 different programs. This PR is about Timewarrior. In Timewarrior, one period can have multiple tags, but they must be started at the same time and ended at the same time (as they are attached to one interval). If someone wants to finish one tag and continue the other, they can stop the current period then start new with only one tag.
