31 Send a patch or a range of patches (defaulting to the applied patches)
32 by e-mail using the 'smtpserver' configuration option. The From/To/Cc
33 addresses and the e-mail format are generated from the template file
34 passed as argument to '--template' (defaulting to
35 .git/patchmail.tmpl). A preamble e-mail can also be sent using the
36 '--first' option (no default template).
38 All the subsequent e-mails appear as replies to the first e-mail sent
39 (either the preamble or the first patch). E-mails can be seen as
40 replies to a different e-mail by using the '--refid' option.
42 SMTP authentication is also possible with '--smtp-user' and
43 '--smtp-password' options, also available as configuration settings:
44 'smtpuser' and 'smtppassword'.
46 The template e-mail headers and body must be separated by
47 '%(endofheaders)s' variable, which is replaced by StGIT with
48 additional headers and a blank line. The patch e-mail template accepts
49 the following variables:
51 %(patch)s - patch name
52 %(shortdescr)s - the first line of the patch description
53 %(longdescr)s - the rest of the patch description, after the first line
54 %(endofheaders)s - delimiter between e-mail headers and body
55 %(diff)s - unified diff of the patch
56 %(diffstat)s - diff statistics
57 %(date)s - current date/time
58 %(patchnr)s - patch number
59 %(totalnr)s - total number of patches to be sent
60 %(authname)s - author's name
61 %(authemail)s - author's email
62 %(authdate)s - patch creation date
63 %(commname)s - committer's name
64 %(commemail)s - committer's e-mail
66 For the preamble e-mail template, only the %(date)s, %(endofheaders)s
67 and %(totalnr)s variables are supported."""
