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
33 address and the e-mail format are generated from the template file
34 passed as argument to '--template' (defaulting to .git/patchmail.tmpl
35 or /usr/share/stgit/templates/patchmail.tmpl). The To/Cc/Bcc addresses
36 can either be added to the template file or passed via the
37 corresponding command line options.
39 A preamble e-mail can be sent using the '--first' option. All the
40 subsequent e-mails appear as replies to the first e-mail sent (either
41 the preamble or the first patch). E-mails can be seen as replies to a
42 different e-mail by using the '--refid' option.
44 SMTP authentication is also possible with '--smtp-user' and
45 '--smtp-password' options, also available as configuration settings:
46 'smtpuser' and 'smtppassword'.
48 The template e-mail headers and body must be separated by
49 '%(endofheaders)s' variable, which is replaced by StGIT with
50 additional headers and a blank line. The patch e-mail template accepts
51 the following variables:
53 %(patch)s - patch name
54 %(maintainer)s - 'authname <authemail>' as read from the config file
55 %(shortdescr)s - the first line of the patch description
56 %(longdescr)s - the rest of the patch description, after the first line
57 %(endofheaders)s - delimiter between e-mail headers and body
58 %(diff)s - unified diff of the patch
59 %(diffstat)s - diff statistics
60 %(date)s - current date/time
61 %(patchnr)s - patch number
62 %(totalnr)s - total number of patches to be sent
63 %(authname)s - author's name
64 %(authemail)s - author's email
65 %(authdate)s - patch creation date
66 %(commname)s - committer's name
67 %(commemail)s - committer's e-mail
69 For the preamble e-mail template, only the %(maintainer)s, %(date)s,
70 %(endofheaders)s and %(totalnr)s variables are supported."""
