Watch flag -w clashes with keyboard navigation and -when

jnd-au commented 3 weeks ago

The unreleased watch flag -w (057fc06) clashes with (a) keyboard navigation and (b) the -when option. That is, if the user:

Specifies the -w watch flag,
And either/both:
- A specific time with -when; or
- Uses left/right keyboard navigation to change the viewed time,
Then a logical paradox occurs without warning:
- The user’s requested time gets overwritten by the next minute’s tickMsg without warning.

What is the behavior you're expecting?

There are multiple possibilities, depending on personal preference, for example:

Emit an error message and abort, due to the conflicting user options
- Pro: Makes sense for -when CLI option
- Con: Doesn’t make sense when the user does left-right interactive keyboard navigation
Disable -w (watch) until t is pressed interactively
- Pro: Full control to the user
- Pro: Make senses when the user does left-right interactive keyboard navigation
- Con: Silent acceptance of conflicting CLI options

I implemented Option 2 in PR #61.
