Just updated all of these scripts. They work with the Anvil file format! Sadly, Minecraft 1.13 breaks it again, and I haven't gotten around to fixing it, but you can run these scripts on version 1.12 maps and they should work fine. You can also download these from Github

These scripts are written in Python, and add various features to a Minecraft savefile. They behave like an automatic editor, altering the contents of an existing world. They do not change the way that Minecraft behaves in any way, and are not considered a mod.
You can download both the script and the interface module to your "saves" folder. Edit the script to set the options. Run it to edit the save file. See the appropriate forum thread for more details. They also work in MCEdit
These are extra wrapper modules to make the above scripts work as filters in MCEdit by Codewarrior. You must copy the script ("Forester.py" for example) as well as the wrapper (MCEditForester.py for example) and the interface file ("mcInterface.py") into the "MCEdit\filters" folder. The filter should show up automatically inside MCEdit. Be sure that all three files are present for each script (NOTE: the mcInterface.py that comes bundled with MCEdit is not up to date! Download the latest version to get things to work properly. (the Forester filter isn't up to date either, download the latest one below)).
The selection box is absolutely respected, so be sure to select a large enough area for the script to do its work.
