'''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.

'''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 --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. You can include a patch both as text in the email
body and as a regular or an inline attachment by combining the
-a/--attach or -i/--inline with the --body option.
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``.
Examples::
hg email -r 3000 # send patch 3000 only
hg email -r 3000 -r 3001 # send patches 3000 and 3001
hg email -r 3000:3005 # send patches 3000 through 3005
hg email 3000 # send patch 3000 (deprecated)
hg email -o # send all patches not in default
hg email -o DEST # send all patches not in DEST
hg email -o -r 3000 # send all ancestors of 3000 not in default
hg email -o -r 3000 DEST # send all ancestors of 3000 not in DEST
hg email -b # send bundle of all patches not in default
hg email -b DEST # send bundle of all patches not in DEST
hg email -b -r 3000 # bundle of all ancestors of 3000 not in default
hg email -b -r 3000 DEST # bundle of all ancestors of 3000 not in DEST
hg email -o -m mbox && # generate an mbox file...
mutt -R -f mbox # ... and view it with mutt
hg email -o -m mbox && # generate an mbox file ...
formail -s sendmail \\ # ... and use formail to send from the mbox
-bm -t < mbox # ... using sendmail
Before using this command, you will need to enable email in your
hgrc. See the [email] section in hgrc(5) for details.
