A fourth alternative is to apply the patch attached below. It combines
the two flagmap dictionaries into one list which is used for both
directions, and it makes this list a global. The first change means
that there is no chance of the two mappings getting out of sync. The
second change means that flagmap can be monkeypatched by code in
.offlineimap.py, such as:
import offlineimap.imaputil as IU
if not hasattr(IU, 'monkeypatchdone'):
IU.flagmap += [('gnus-expire','E'),
IU.monkeypatchdone = True
The patch should produce results identical with the old code. It just
allows for easier customization. (And it doesn't recreate the flagmap
dictionaries every time the flag functions are called, so it might even
be more efficient. It also renames the variable list to another name,
to avoid shadowing the list class.)
I still like my second and third ideas above, but this fourth method
will at least allow users with special needs to handle custom flags.
The monkeypatching code above could be put in a FAQ somewhere, or in the
advanced section of the default .offlineimaprc file.
PS: Can someone confirm that my messages are making it through?
