The easiest is to run pip3 install --user git+https://github.com/karlicoss/rescuexport.
Alternatively, you can git clone --recursive and use pip3 install --editable
Usage:
Recommended: create secrets.py keeping your api parameters, e.g.:
key = "KEY"
After that, use:
./export.py --secrets /path/to/secrets.py
That way you type less and have control over where you keep your plaintext secrets.
Alternatively, you can pass parameters directly, e.g.
./export.py --key <key>
However, this is verbose and prone to leaking your keys/tokens/passwords in shell history.
I highly recommend checking exported files at least once just to make sure they contain everything you expect from your export. If not, please feel free to ask or raise an issue!
