One of the nice features of Bazaar is the ability to send a bundle of changes to someone via email. If you use a supported mail client, it will even open the composer with the changes attached. If your client isn’t supported, then it’ll let you compose a message in your editor and then send it to an SMTP server.
GMail is not a supported mail client, but there are a few work arounds listed on the wiki. Those really come down to using an alternative mail client (either the editor or Mutt) and sending the mails through the GMail SMTP server. Neither solution really appealed to me. There doesn’t seem to be a programatic way of opening up GMail’s compose window and adding an attachment (not too surprising for a web app).
What is possible though is connecting via IMAP and adding messages to the drafts folder (assuming IMAP support is enabled). So I wrote a small plugin to do just that. It can be installed with the following command:
bzr branch lp:~jamesh/+junk/bzr-imapclient ~/.bazaar/plugins/imapclient
And then configure the IMAP server, username and mailbox according to the instructions in the README file. You can then use “bzr send” as normal and then complete and send the draft at your leisure.
One nice thing about the plugin implementation is that it didn’t need any GMail specific features: it should be useful for anyone who has their drafts folder stored on an IMAP server and uses an unsupported mail client.
The main area where this could be improved would be to open up the compose screen in the web browser. However, this would require knowing the internal message ID for the new message, which I can’t see how to access via IMAP.
