# patchbomb.py - sending Mercurial changesets as patch emails # # Copyright 2005-2009 Matt Mackall <mpm@selenic.com> and others # # This software may be used and distributed according to the terms of the # GNU General Public License version 2 or any later version. '''command to send changesets as (a series of) patch emails The series is started off with a "[PATCH 0 of N]" introduction, which describes the series as a whole. Each patch email has a Subject line of "[PATCH M of N] ...", using the first line of the changeset description as the subject text. The message contains two or three body parts: - The changeset description. - [Optional] The result of running diffstat on the patch. - The patch itself, as generated by :hg:`export`. Each message refers to the first in the series using the In-Reply-To and References headers, so they will show up as a sequence in threaded mail and news readers, and in mail archives. To configure other defaults, add a section like this to your configuration file:: [email] from = My Name <my@email> to = recipient1, recipient2, ... cc = cc1, cc2, ... bcc = bcc1, bcc2, ... reply-to = address1, address2, ... Use ``[patchbomb]`` as configuration section name if you need to override global ``[email]`` address settings. Then you can use the :hg:`email` command to mail a series of changesets as a patchbomb. You can also either configure the method option in the email section to be a sendmail compatible mailer or fill out the [smtp] section so that the patchbomb extension can automatically send patchbombs directly from the commandline. See the [email] and [smtp] sections in hgrc(5) for details.

[DEST]...')) def patchbomb(ui, repo, *revs, **opts): '''send changesets by email By default, diffs are sent in the format generated by :hg:`export`, one per message. The series starts with a "[PATCH 0 of N]" introduction, which describes the series as a whole. Each patch email has a Subject line of "[PATCH M of N] ...", using the first line of the changeset description as the subject text. The message contains two or three parts. First, the changeset description. With the -d/--diffstat option, if the diffstat program is installed, the result of running diffstat on the patch is inserted. Finally, the patch itself, as generated by :hg:`export`. With the -d/--diffstat or -c/--confirm options, you will be presented with a final summary of all messages and asked for confirmation before the messages are sent. By default the patch is included as text in the email body for easy reviewing. Using the -a/--attach option will instead create an attachment for the patch. With -i/--inline an inline attachment will be created. With -o/--outgoing, emails will be generated for patches not found in the destination repository (or only those which are ancestors of the specified revisions if any are provided) With -b/--bundle, changesets are selected as for --outgoing, but a single email containing a binary Mercurial bundle as an attachment will be sent. With -m/--mbox, instead of previewing each patchbomb message in a pager or sending the messages directly, it will create a UNIX mailbox file with the patch emails. This mailbox file can be previewed with any mail user agent which supports UNIX mbox files. With -n/--test, all steps will run, but mail will not be sent. You will be prompted for an email recipient address, a subject and an introductory message describing the patches of your patchbomb. Then when all is done, patchbomb messages are displayed. If the PAGER environment variable is set, your pager will be fired up once for each patchbomb message, so you can verify everything is alright. In case email sending fails, you will find a backup of your series introductory message in ``.hg/last-email.txt``.
