Formatting Percentage Value

[faxotherapy]

Hi, I try to use @cpu_percentage_format. The little annoying thing is seeing percentage position moving back and forth, for example, from 8% to 10%, then 10 to 8. I'd like to have 08% or [space]8% instead of 8% so that I no longer see the percentage position moving back and forth on the right side of the status bar.

you can use (in .tmux.conf):

set -g @cpu_percentage_format "%3.0f%%"
set -g @gpu_percentage_format "%3.0f%%"

Note the 3.0 means [space][space]8, [space]10 and 100. If you only want to reserve 2 chars (and allow 100 to take an extra char) then use 2.0

Hi, thanks for your reply. Unfortunately, it does not work. Is there any specific order in tmux.conf where I should put this setting, because as such, it does no work. What I'd like is having the CPU label not moving all the time, because it causes some distraction.

you need to reload https://sanctum.geek.nz/arabesque/reloading-tmux-config/

Thanks for the tip, but it does not work either. I'm running tmux 2.8

@faxotherapy can you share your config files please?

@faxotherapy I've reduced your config to a minimal subset and it's working for me.

set -g @cpu_percentage_format "%3.0f%%"

Are you sure to have the latest tmux-cpu ?

According to this line in your config

set -g @cpu_percentage_format "%3.0f%%"

you shouldn't see decimals but there is decimal in your gif

So if it still not working after tmux-cpu upgrade, there's probably something wrong in the rest of your config file.
