Step 2: 🧐 Snippet Analysis

From looking through the relevant snippets, I decided to make the following modifications:

File Path	Proposed Changes
bin/bluetooth/bluetooth-connect	Modify this script to write the name of the connected device to a file. This can be done by adding a line at the end of the connect function to echo the device name to a file, like so: echo "$1" > /tmp/connected_bluetooth_device.
bin/bspwm/bar	Modify this script to read the file containing the name of the connected Bluetooth device and display it on the bar. This can be done by adding a new function to read the file and echo its contents, and then calling this function in the _modules function. The new function could look like this:
	```bash
	_bluetooth() {
	if [ -f /tmp/connected_bluetooth_device ]; then
	local device_name
	device_name=$(cat /tmp/connected_bluetooth_device)
	echo "%{F$fg_alt}Bluetooth:%{F-} $device_name"
	fi
	}
	```
	And then in the _modules function, add a call to _bluetooth like so:
	```bash
	_modules() {
	while true; do
	echo "B" "$(_battery)"
	echo "T" "$(_temperature)"
	echo "D" "$(_datetime)"
	echo "K" "$(_keyboard)"
	echo "V" "$(_volume)"
	echo "BL" "$(_bluetooth)"
	sleep 1s
	done
	}
	```

Step 3: 📝 Planning

I have created a plan for writing the pull request. I am now working my plan and coding the required changes to address this issue. Here is the planned pull request:

Add currently connected Bluetooth device name to lemonbar script
sweep/add-bluetooth-device-name

Description

This PR adds functionality to display the currently connected Bluetooth device name on the lemonbar script in bin/bspwm/bar.

Changes Made

• Modified bin/bluetooth/bluetooth-connect script to write the name of the connected device to a file /tmp/connected_bluetooth_device.
• Added _bluetooth function to bin/bspwm/bar script to read the file and display the device name on the bar.
