Powerlevel10k Prompt Segment (zsh)

[mayurankv]

I wrote a prompt segment for powerlevel10k (zsh prompt) which uses the TCP server to report the current layer in kanata. The main issue is that the prompt obviously only re-renders when a command goes through so it doesn't update when the prompt is unchanged. Looking to see if I can re-render the prompt when kanata sends a message. If anyone has any extensions or improvements, please let me know! Hope this helps others!

zmodload zsh/net/tcp

typeset -gA unicode_map=(
	qwerty 'QWE'
	colemak 'COL'
	dvorak 'DVO'
	layers $'\ueea8'
	numpad '123'
	symbols 'SYMB'
	delimiters '()'
	navigation 'NAV'
	movement 'MOV'
)
default_value=$'\uf12a'

function prompt_my_kanata() {
ztcp 127.0.0.1 ${MYKANATAPORT-5829}
if [[ -n "${REPLY:-}" ]]; then
	read -r line <&$REPLY
	if [[ "$line" =~ \{\"LayerChange\":\{\"new\":\"([^\"]+)\"\}\} ]]; then
		layer="${match[1]}"
		icon=${unicode_map[$layer]:-$default_value}
		p10k segment -s "$layer" -i '' -f blue -t "$icon"
	fi
	exec {REPLY}<&-
fi
}
