Command Line Usage

Ultimately afew is a command line tool. You have to specify an action, and whether to act on all messages, or only on new messages. The actions you can choose from are:

tag

run the tag filters. See Initial tagging.

watch

continuously monitor the mailbox for new files

move-mails

move mail files between maildir folders

Initial tagging

Basic tagging stuff requires no configuration, just run

$ afew --tag --new
# or to tag *all* messages
$ afew --tag --all

To do this automatically you can add the following hook into your ~/.offlineimaprc:

postsynchook = ionice -c 3 chrt --idle 0 /bin/sh -c "notmuch new && afew --tag --new"

There is a lot more to say about general filter Configuration and the different Filters provided by afew.

Simulation

Adding –dry-run to any –tag or –sync-tags action prevents modification of the notmuch db. Add some -vv goodness to see some action.

Move Mode

To invoke afew in move mode, provide the –move-mails option on the command line. Move mode will respect –dry-run, so throw in –verbose and watch what effects a real run would have.

In move mode, afew will check all mails (or only recent ones) in the configured maildir folders, deciding whether they should be moved to another folder.

The decision is based on rules defined in your config file. A rule is bound to a source folder and specifies a target folder into which a mail will be moved that is matched by an associated query.

This way you will be able to transfer your sorting principles roughly to the classic folder based maildir structure understood by your traditional mail server. Tag your mails with notmuch, call afew –move-mails in an offlineimap presynchook and enjoy a clean inbox in your webinterface/GUI-client at work.

For information on how to configure rules for move mode, what you can do with it and what you can’t, please refer to Move Mode.
