Bug: Error obtaining wireless information on desktop Macs

[moussaclarke]

Describe the bug

On desktop Macs, e.g. a macMini, the network shows as "Error obtaining Wireless information"

To Reproduce

Steps to reproduce the behavior:

1. On a desktop mac connected to WiFi, add the network plugin
2. Open tmux
3. Look at the status line

Expected behavior

Status line should show the network SSID

Screenshots

System

• OS: mac OS X 14.4.1
• Tmux Version: 3.4

I think what's going on is that en1 is wifi on desktop macs, not en0, so probably need to check which interface is active before calling networksetup

e.g. active=$(ifconfig | awk '/en0/ && /inet/ {print "en0"} /en1/ && /inet/ {print "en1"}')

This fixes it for me moussaclarke@970eab2

Can submit as PR if appropriate.

This fix does not work in the scenario where wither wired or both wireless and wired connections are used. Command networksetup -getairportnetwork $interface | cut -d ':' -f 2 | sed 's/^[[:blank:]]*//g' responses with

en0 is not a Wi-Fi interface.
Error obtaining wireless information.

Ok I guess we could fall back to Ethernet if we get that response from networksetup -getairportnetwork on the active interface.

Otherwise when I get a minute I'll see if I can figure out a less indirect way of checking the type of connection before calling networksetup -getairportnetwork - probably via ifconfig again

@oiavorskyi updated: moussaclarke@9770d37

I couldn't find a straightforward way to get the connection type, so just checking for the presence of the error message string. Feels somewhat brittle though? Also added a "No connection" status

Will test it on a wired connection when I get the chance.

@moussaclarke sorry for not responding in a very long time, I was on a vacation. Maybe it is possible to use the result of
networksetup -listallhardwareports | awk '/Hardware Port: Wi-Fi/{getline; print $2}'
to check which interface(s) are WiFi ones and then see if it is used a an active interface?
