This configuration was simply copied from my old Arch Linux system. There are some issues that still need to be solved, namely with fonts and missing bitcoin price script, but it's mostly minor.

"""This is a utility script for regex remaps on window names.
|
|
|
|
This is done in python, because of the complex regex logic, which would be pretty hard to
|
|
recreate in bash. This python script is expected to be called from the bash script controlling
|
|
the window names. Window name and class are obtained from piped stdin, to prevent having to
|
|
needlessly keep restarting this program, which takes a while due to the interpreter starting
|
|
overhead.
