Using Google App Scripts to share documents - google-apps-script

Question

I have so many documents that I need to manage due to the amount of people that have access to them, and when someone needs to be added or removed, it can become a real pain and time consumer.
I'm curious, is there a script that you can set across multiple documents that give edit or view access.
I'm aware that there is this, "addEditor(emailAddress)", but from what I have gathered, you have to do a script for each document which defeats the purpose of productivity.
Basically, I need one script that gives access to a particular set of documents, and when I need someone removed, i just delete their name and run the script and removes edit/view access from those documents.
Ax example of a script, or rather what I'm trying to achieve. (Not actually a script):
//Human Resources//
addEditor(emailAddress) to BBM1 - Membership Tracker, "https://docs.google.com/spreadsheets/d/1gb8T1K74cRR_6qSyByqrtiphujrchceLP_QsMunoras/edit#gid=0"
//Administrator//
addEditor(emailAddress) to BBM1 - Membership Tracker, "https://docs.google.com/spreadsheets/d/1gb8T1K74cRR_6qSyByqrtiphujrchceLP_QsMunoras/edit#gid=0"
//Moderator//
addViewer(emailAddress) to BBM1 - Membership Tracker, "docs.google.com/spreadsheets/d/1gb8T1K74cRR_6qSyByqrtiphujrchceLP_QsMunoras/edit#gid=0"
So basically, I can just add emails to that, run the script, and it gives them edit access. But, I just don't know how to create a script that actually works for that and also to have a script across multiple documents.
Many Thanks,
Shaun.

Take a look on folder api. You can put all those files into a folder, and then everytime you run the script you can loop through all files in the folder and set correct permissions.
Example (untested):
var folderName = "My auto-managed documents";
var folderIterator = DriveApp.getFoldersByName(folderName);
while (folderIterator.hasNext()) {
var folder = folderIterator.next();
var fileIterator = folder.getFiles();
while (fileIterator.hasNext()) {
var file = fileIterator.next();
// Do things with the file:
// file.addEditor('my-email#example.com');
}
}
