I really liked it, if you have updated it I would like to know.
Especially if you have or could add git(branch [master | +2 -1 ] eg.) to it.
I moved away from SH/Bash to ZSH some time ago, however, I can look at adding that.
Thanks for this amazing work, I saw you left the enable variables but they weren't used in the code. I updated it to use them.

This is really cool! Reminds me of the kali-linux prompts. I do notice one thing namely if I do sudo -s the user name of root or the userthat did sudo is not shown. On RHEL 7 for example out-of-the-box when somone does sudo -s to root the promt is of the form [root@<host> <user>]. With your code both root and user are missing resulting in for example [22:00:14]─[!VDI-W10]─[/home/me]. The apsect of the RHEL prompt that shows the caller of sudo if very useful in my opinion.

hey ... i used this, It's good, but i get :
bash: warning: command substitution: ignored null byte in input
bash: warning: command substitution: ignored null byte in input
Coming from these two lines :
local parent_process=$(cat /proc/$PPID/cmdline | cut -d . -f 1)
local my_process=$(cat /proc/$$/cmdline | cut -d . -f 1)
Any idea why ?
