Cannot display colors with watch

[autra]

Description

dysk never outputs color with watch -c.

I'd expect this usage to be possible with --color yes (or force?).

steps to reproduce

• use watch -c dysk --color yes

expected the output is colored

actual output is not colored.

additional info

Some tools behaves this way. Ex the crate dua does output colors when executing watch -c dua.

This is weird. It looks like watch removes the color, I have no idea why.

Try this:

dysk --color yes > colored

Then you can check the output is colored with

cat colored

But if you do

 watch -c cat colored

then there's no color.

I also checked there's no problem with neowatch.

[autra]

watch + dua do work though. No idea what's going on 😆

Thanks for neowatch! I didnt know this one.

I think a better solution would be to add a '--polling x' flag to the program to have it handle persisting. I would default to 300 seconds (5 mins) since it is high level enough where you might not need 5 seconding polling intervals by default.

[Canop]

Even if it probably addresses the original motivation behind this issue, I think the polling feature would be better discussed in a dedicated GitHub issue.

I can throw a req entry in if that would help keep things organized.

Why adding a polling feature when plenty of external tools (watch, neowatch etc...) can do this?

The same reasons we have tools like HTOP, TOP, BTOP rather than throwing down a watch command with a ps -ef. It's easier to manage and integrate.
