i3status VS i3blocks-contrib

My time display is in i3status, but that doesn't help you if you're using Windows.

Here is the default config on github - https://github.com/i3/i3status/blob/master/etc/i3status.conf

You need to append your custom arguments using JSON. You can look at this example here: https://github.com/i3/i3status/blob/master/contrib/net-speed.sh

https://github.com/i3/i3status/blob/2.13/i3status.c#L830

It sounds like you're asking how i3status rewrites the existing output line when you run it in a terminal. It and other programs that do this (e.g. long running commands with progress bars) use terminal escape codes. The relevant source line (as best I can tell) is at https://github.com/i3/i3status/blob/30a32cce3a16e6c79a81aad467cfe13c12e688cb/i3status.c#L662

Otherwise, the source for the wireless portion of i3status appears to be here: https://github.com/i3/i3status/blob/master/src/print_wireless_info.c

https://github.com/vivien/i3blocks-contrib/pull/484 (or https://github.com/shivankgarg98/i3blocks-contrib/tree/master/screenshot)

I made a wrapper around the mediaplayer module for i3blocks from the orignal contrib repo: https://github.com/vivien/i3blocks-contrib

I tried adding some i3status modules from https://github.com/vivien/i3blocks-contrib

There's a script at https://github.com/vivien/i3blocks-contrib/tree/master/bandwidth/bandwidth that might work for you with a bit of messing about.

For example, when I copy the battery script (https://github.com/vivien/i3blocks-contrib/tree/master/battery) into my i3blocks.conf, it doesn't work.
