Share Your Shell 'Plugins'

🐚

Got something cool working with spacebar's shell options? 😎 Share the config and/or script!
Want to implement something but you're not quite sure how? 🤔 Go ahead and ask!

Note: Providing more of these "slots" is planned for a future release

I'll get things kicked off with a couple simple outputs I've been using :)

Unread e-mail indicator

I use mu/mu4e for e-mail inside Emacs. I can lose track of my e-mail throughout the day, but have been doing better since I added this (apart from today, clearly!)

spacebar -m config right_shell on
spacebar -m config right_shell_command "mu find 'm:/work/inbox' flag:unread | wc -l | tr -d \"[:blank:]\""
spacebar -m config right_shell_icon 

As you can see, it's for my work inbox, but could probably quite easily be switched out to evaluate mu4e-context-current via emacsclient

Current Kubernetes context/namespace

One for the engineers :)

spacebar -m config right_shell_command /path/to/script.sh
spacebar -m config right_shell_icon 

Where script.sh is:

#! /usr/bin/env bash

CONTEXT=$(kubectl config current-context)
NAMESPACE=$(kubectl config view --minify --output 'jsonpath={..namespace}')
echo "${CONTEXT}:${NAMESPACE}"

Current track information from mpd

Showing just artist, album and status for mpd using mpc.

Configuration

spacebar -m config title                off
spacebar -m config center_shell         on
spacebar -m config center_shell_command "$HOME/.config/spacebar/mpd"

Script

#! /usr/bin/env bash

STATUS="$(/usr/local/bin/mpc status 2>/dev/null)"

if [ $(echo "$STATUS" | wc -l | tr -d ' ') == "1" ]; then
  output="Queue up some tunes!"
else
  artist=$(echo "$STATUS" | awk -F" - " 'NR==1{print $1}')
  song=$(echo "$STATUS"   | awk -F" - " 'NR==1{print $2}')
  status=$(echo "$STATUS" | awk         'NR==2{print $1}')

  if [ $status = "[playing]" ]; then
    status="Playing"
  else
    status="Paused"
  fi

  output="${artist} • ${song} • ${status}"
fi

echo $output

CPU Utilization:

Config:

spacebar -m config right_shell_command  "$HOME/spacebar_scripts/cpu.sh"

Script:

#! /usr/bin/env bash

ps -axro pcpu | awk '{sum+=$1} END {print "%"sum}'

Keyboard Language:

Config:

spacebar -m config right_shell_command ~/bin/keyboard-layout.sh

Script:

#!/usr/bin/env bash

osascript -e 'tell application "System Events" to tell process "SystemUIServer" to get the value of the first menu bar item of menu bar 1 whose description is "text input"'

That being said, it would be helpful to have a "force spacebar to update" function as there is a severe delay, the shell script running only every 5 seconds

[cmacrae]

Very nice! As pointed out in the issue you raised, you can expect higher refresh frequencies (per module) in the rewrite :) You can also hack around this limitation in the current implementation with:

while sleep 1 ; do spacebar -m config left_shell_command "date" ; done

For example. This will draw the shell output of date every second

osascript -e 'tell application "System Events" to tell process "SystemUIServer" to get the value of the first menu bar item of menu bar 1 whose description is "text input"'

This does not work for me (macOS Big Sur).

These work for me, however (source)

defaults read ~/Library/Preferences/com.apple.HIToolbox.plist AppleSelectedInputSources | egrep -w'KeyboardLayout Name' | sed -E 's/^.+ = \"?([^\"]+)\"?;$/\\1/'

defaults read ~/Library/Preferences/com.apple.HIToolbox.plist AppleSelectedInputSources | command rg -e '"KeyboardLayout Name" = "*([^"]*)"*;' --replace '$1' --only-matching --color never

Wifi SSID and speed

network.sh

#!/bin/bash

output=$(/System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport -I)
airport=$(echo "$output" | grep 'AirPort' | awk -F': ' '{print $2}')

if [ "$airport" = "Off" ]; then
  echo "Offline"
else
  echo "$(echo "$output" | grep ' SSID' | xargs | awk -F': ' 'echo $2')" \
    "$(echo "$output" | grep 'lastTxRate' | awk -F': ' '{print $2}')" Mb/s
fi

spacebarrc

spacebar -m config right_shell        on
spacebar -m config right_shell_icon   
spacebar -m config right_shell_command "$HOME/.config/spacebar/network_speed.sh"

[anujc4]

Additionally, the "SSID: " prefix can also be removed by appending | sed 's/SSID: //') to the output

[cmacrae]

Very nice! 👏

I wrote script for checking Wi-Fi signal quality (RSSI / Noise) :

#!/usr/bin/env bash

# Created by Andrzej Zahorski :)
result=$(/System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport -I \
    | grep "CtlRSSI\|agrCtlNoise" \
    | sed -e 's/^.*://g'  | { read -r a; read -r b; printf '%s\n' $((a-b)); })

printf 'Wi-Fi: '
# echo $result
if ((result > 40))
then
    echo "[++++]"
elif ((result > 25 && result <= 40))
then
    echo "[+++-]"
elif ((result > 15 && result <= 25))
then
    echo "[++--]"
elif ((result > 10 && result <= 15))
then
    echo "[+---]"
elif (( result > 0 &&result < 10  ))
then
    echo "[----]"
elif (( result == 0 ))
then
    echo "Off"
fi

I wrote a quick python script for collecting the current bitcoin price and the 24 hours percentage change from Coinmarketcap. However, it requires that you python3 installation has bs4 and requests.

spacebar -m config right_shell          on
spacebar -m config right_shell_icon     ""
spacebar -m config right_shell_command  "$HOME/.scripts/crypto"

#!/usr/bin/env python3
from bs4 import BeautifulSoup
import requests
import json
import sys

fiat = 'BTC'
if len(sys.argv) > 1:
    fiat = sys.argv[1]

if fiat.lower() == 'eth':
    cur = 1
    idx = '1027'
else:
    cur = 0
    idx = '1'
url = 'https://coinmarketcap.com/currencies/bitcoin'

cmc = requests.get(url)
soup = BeautifulSoup(cmc.content, 'html.parser')
data = soup.find('script', id='__NEXT_DATA__', type='application/json')
data = json.loads(data.contents[0])
crypt_data = data['props']['initialState']['cryptocurrency']['quotes'][idx]

percentChange = crypt_data['fmc24hpc']
price = crypt_data['p']
# percentChangeFormat = '<span color="{}">{}{:.2f}%</span>'
percentChangeFormat = '{}{:.2f}%'
precision = 2
if percentChange > 0:
    # percentChangeInfo = percentChangeFormat.format('#3BB92D', '', percentChange)
    percentChangeInfo = percentChangeFormat.format('', percentChange)
elif percentChange == 0:
    # percentChangeInfo = percentChangeFormat.format('#CCCCCC', '', percentChange)
    percentChangeInfo = percentChangeFormat.format('', percentChange)
else:
    # percentChangeInfo = percentChangeFormat.format('#F7555E', '', percentChange)
    percentChangeInfo = percentChangeFormat.format('', -percentChange)
print(('${:.' + str(precision) + 'f} {}').format(price, percentChangeInfo))  # Full Text

Here's a script to display the Current State of the Music App and/or current track information. It could use some tweaking particularly for long titles. It's kind of sloppy, but it works pretty well.

If anyone knows if there's a way to dynamically update the icon that would be great. My full script switches between a few different things like, stocks, music, etc. I've tried to put it in the script but it doesn't seem to work and spacebar stops responding.

MUSIC_INFO=$(osascript <<EOF
on titleCase(theString)
	set UpperFirstCharString to do shell script "echo " & character 1 of theString & " | tr [:lower:] [:upper:]"
	set theString to UpperFirstCharString & characters 2 through -1 of theString
	return theString
end titleCase

on appRunning(appName)
	if application appName is running then
		return true
	else
		return false
	end if
end appRunning

on musicPlaying()
	tell application "Music"
		set playerState to (get player state) as text
	end tell
	
	if playerState is "paused" then
		set stateIcon to " "
	else if playerState is "stopped" then
		set stateIcon to " "
	else if playerState is "playing" then
		set stateIcon to " "
	end if
		
	if playerState is not "stopped" then
		return {true, titleCase(playerState), stateIcon}
	else
		return {false, titleCase(playerState), stateIcon}
	end if
end musicPlaying

on getTrackInfo()
	set appRunning to appRunning("Music")
	set musicPlaying to musicPlaying()	
	
	if appRunning is true then
		if item 1 of musicPlaying is true then
			tell application "Music"
				set info to get {name, artist, album} of current track
				return "" & item 3 of musicPlaying & "  " & item 1 of info & " x " & item 2 of info & " - " & item 3 of info
			end tell
		else
			return item 3 of musicPlaying & "  Music Stopped "
		end if
	else
		return "    Music App Not Running "
	end if
end getTrackInfo

getTrackInfo()
EOF
)

printf "$MUSIC_INFO"

Used the same idea but made changes so it applies to spotify.app

MUSIC_INFO=$(osascript <<EOF
on titleCase(theString)
   set UpperFirstCharString to do shell script "echo " & character 1 of theString & " | tr [:lower:] [:upper:]"
   set theString to UpperFirstCharString & characters 2 through -1 of theString
   return theString
end titleCase

on appRunning(appName)
   if application appName is running then
   	return true
   else
   	return false
   end if
end appRunning

on getTrackInfo()
   set appRunning to appRunning("Spotify")
   
   if appRunning is true then
   	tell application "Spotify"
   		set info to get {name, artist} of current track
   		return "  " & item 1 of info & " x " & item 2 of info
   	end tell
   else
   	return "    Spotify App Not Running "
   end if
end getTrackInfo

getTrackInfo()
EOF
)

printf "$MUSIC_INFO"
