Utilities to enable CPU Activity as a touchbar widget

This allows the touchbar to display a graph of the CPU activity over the last 100 seconds by interval of 5 seconds.

This utility simply returns the CPU activity in percent (%) beware that this is the sum of the activity percentage of each of your cores, so if you have 4 cores. Your maximum activity is 400%

This utility add the current CPU activity to the /tmp/cpu.log file and only keep the last 20 entries. It also prints the content of the file to stdout.

This script reads off the /tmp/cpu.log file, parses it, and generates a graph in heic format at location /tmp/cpulogimage.heic. It also prints out the JSON file that will be interpreted by BTT in order to update the icon in the touchbar with the new image.

Since my own laptop has 4 cores I divide the percentage by 400. If you have more (or less) cores you might want to change the "coreCount" variable in this file.

Pull the project with

git pull https://github.com/andrevidela/CPU-Activity-Touchbar.git

Then go into its directory

cd CPU-Activity-Touchbar

Here, you can use the install.sh script to symlink those utilities to your location of your preference by giving it the path as argument. I personally put them in /usr/local/bin. Which means I use the script like that

sh install.sh /usr/local/bin

In order for this to work you will need BetterTouchTool and you will have to add a new button in your touchbar.

1. First create a new TouchBar trigger
2. Select TouchBar Widget and then Shell script/Task widget
3. In the Script field enter the following program:

cpuHistory > /dev/null
cpuGraph

You can tweak the refresh rate by selecting another time interval.
