with this double quoting, look at PS1 after assignment:
Your variables are expanded inside of a double-quote before assignment. If you escape the $ then it will be stored inside of PS1. You can also use single quotes to avoid expansion, but you have some in there so those are the 1 character you need to treat special inside single quotes:
Having a command execute for each prompt is a bit much. Also maybe you'd like to make it a function and handle those fatal errors in case you leave a git branch.
et voila!?

env::ps1
Env::PS1(3pm) User Contributed Perl Documentation Env::PS1(3pm)NAME
Env::PS1 - prompt string formatter
SYNOPSIS
# use the import function
use Env::PS1 qw/$PS1/;
$ENV{PS1} = 'u@h $ ';
print $PS1;
$readline = <STDIN>;
# or tie it yourself
tie $prompt, 'Env::PS1', 'PS1';
# you can also tie a scalar ref
$format = 'u@h$ ';
tie $prompt, 'Env::PS1', $format;
DESCRIPTION
This package supplies variables that are "tied" to environment variables like 'PS1' and 'PS2', if read it takes the contents of the
variable as a format string like the ones bash(1) uses to format the prompt.
It is intended to be used in combination with the various ReadLine packages.
EXPORT
You can request for arbitrary variables to be exported, they will be tied to the environment variables of the same name.
TIE
When you "tie" a variable you can supply one argument which can either be the name of an environement variable or a SCALAR reference. This
argument defaults to 'PS1'.
METHODS
"sprintf($format)"
Returns the formatted string.
Using this method all the time is a lot less efficient then using the tied variable, because the tied variable caches parts of the
format that remain the same anyway.
FORMAT
The format is copied mostly from bash(1) because that's what it is supposed to be compatible with. We made some private extensions which
obviously are not portable.
Note that this is not the prompt format as specified by the posix specification, that would only know "!" for the history number and "!!"
for a literal "!".
Apart from the escape sequences you can also use environment variables in the format string; use $VAR or "${VAR}".
The following escape sequences are recognized:
a The bell character, identical to "
