For a simple version

# Prepending emoji to the current PS1
echo "\n#Emoji PS1\nPS1=\"\\\$(node $PWD/emoji.js) \"\$PS1" >> ~/.bashrc
source ~/.bashrc

For animations, copy the psanimate and psanimate_stop functions from the /emoji.zsh-theme file to ~/.bashrc

If you face issues with node, install/update node to the latest stable version. This was developed on v16.6.0

:spiral_calendar: Schedule

The emoji.js file contains the logic behind the what emoji to show and when. There's a Schedule for the emoji which you can/should change in JS here.

const timings = [
  // from, duration, emoji, highlight?, unstoppable?
  [0, 500, '🛌', true, true],
  [530, 200, getRandom(activity_list)],
  [800, 200, '🥪', true],
  [1300, 130, '🍛', true],
  ...

The highlight flag shows an arrow ⬅ after the emoji <img width="1123" alt="Screenshot 2021-08-30 at 21 33 31" src="https://user-images.githubusercontent.com/2320747/131369199-3f87ad67-dd0e-4726-a044-e472312ee157.png"> The unstoppable flag says that the scheduled emoji cannot be overridden by

You can/should edit these two lists as well depending your interests, likes and visually appealing emojis.

const fun_list = "👾,🍀,🥑,⛰️ ,🪂,🍺,👨🏻‍🌾,🐢,🐼,🐙,🐳,🐓,🪵 ,🍄,🔥,🌪 ,🍁,🐚,🌊,🍉,🥝,🍋".split(',')
const activity_list = '🎨,🦮,📚,✍️ ,🎸,🛹,🏃🏻‍♂️'.split(',')

🎮 Animation

All of these could be animated. You can start the animation with the command (bash function) psanimate <interval-in-seconds>, defaults to 1 second. Animate calls the emoji function in the given interval with a rotating SWITCH boolean.

The following is dinner-time highighted emoji with psanimate .2

Animation runs as a background process, stores the pid in /tmp/psanimatepid-$$.

🦾 Automating animations

This is disabled by default since automated animations could be very much annoying. But you can enable it by setting the PS_AUTO_ANIMATE variable. The schedule and check-interval is in the function right below the variable. By default it checks every 30 minutes and animates during sleep time.

PS_AUTO_ANIMATE=1

✅ Finishing tasks

Certain activity emojis like food can be overridden (when it's over). This can be done with the command pstaskover. This sets the env variable PS_TASK_OVER and so an emoji from the fun_list is picked up after.

The PS_TASK_OVER resets after an hour. It uses bash traps.
