"""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.
