I need to run a script before each build. It is a script to insert an html file into a c++ source file. I don’t know python but I can learn it. An example program to do simple file operations would be great.
I looked at the docs but all I see if gobbledegook to my simple mind. There is all sorts of stuff about environment variables and I don’t understand why it is needed. Can’t a simple python script run that is specified in platformio.ini?
