'''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 -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``.
|
|
|
|
|
|
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.
