Interpolation just provide variables. The declared variable must be
used later in the config file.

Here is what might worth the try:

call_pass = get_pass(%(account_name))

account_name = ACCOUNT_NAME
remotepasseval = call_pass

IOW, it's not possible to trash the remotepasseval in the remote

What I'm not 100% sure is that interpolation can work for variables
defined after they are used.

You have to define all the variables yourself. Since we can't remove the
remotepasseval lines in the Repository sections, it's easier to not use
interpolation like this:

remotepasseval = get_pass('ACCOUNT_NAME')

AFAIK, there are no predefined variables. The interpolation comes from
the configparser module. The official doc is:

I would just print() the values instead of writing them to a file.


If you have a lot of accounts, you might like to build the config file
with a script of your own and use a template system. For a script
written in python there is jinja2 (usually used for the web but this can
be used in a script).

Also, you might like to split your config file and have one config file
per account. Then, call offlineimap with

  offlineimap -c CONFIG_FILE_PATH
