32 Send a patch or a range of patches by e-mail using the SMTP server
33 specified by the 'stgit.smtpserver' configuration option, or the
34 '--smtp-server' command line option. The From address and the e-mail
35 format are generated from the template file passed as argument to
36 '--template' (defaulting to '.git/patchmail.tmpl' or
37 '~/.stgit/templates/patchmail.tmpl' or
38 '/usr/share/stgit/templates/patchmail.tmpl'). A patch can be sent as
39 attachment using the --attach option in which case the 'mailattch.tmpl'
40 template will be used instead of 'patchmail.tmpl'.
42 The To/Cc/Bcc addresses can either be added to the template file or
43 passed via the corresponding command line options. They can be e-mail
44 addresses or aliases which are automatically expanded to the values
45 stored in the [mail "alias"] section of GIT configuration files.
47 A preamble e-mail can be sent using the '--cover' and/or
48 '--edit-cover' options. The first allows the user to specify a file to
49 be used as a template. The latter option will invoke the editor on the
50 specified file (defaulting to '.git/covermail.tmpl' or
51 '~/.stgit/templates/covermail.tmpl' or
52 '/usr/share/stgit/templates/covermail.tmpl').
54 All the subsequent e-mails appear as replies to the first e-mail sent
55 (either the preamble or the first patch). E-mails can be seen as
56 replies to a different e-mail by using the '--refid' option.
58 SMTP authentication is also possible with '--smtp-user' and
59 '--smtp-password' options, also available as configuration settings:
60 'smtpuser' and 'smtppassword'. TLS encryption can be enabled by
61 '--smtp-tls' option and 'smtptls' setting.
63 The following variables are accepted by both the preamble and the
64 patch e-mail templates:
66 %(diffstat)s - diff statistics
67 %(number)s - empty if only one patch is sent or ' patchnr/totalnr'
68 %(patchnr)s - patch number
69 %(sender)s - 'sender' or 'authname <authemail>' as per the config file
70 %(totalnr)s - total number of patches to be sent
71 %(version)s - ' version' string passed on the command line (or empty)
73 In addition to the common variables, the preamble e-mail template
74 accepts the following:
76 %(shortlog)s - first line of each patch description, listed by author
78 In addition to the common variables, the patch e-mail template accepts
81 %(authdate)s - patch creation date
82 %(authemail)s - author's email
83 %(authname)s - author's name
84 %(commemail)s - committer's e-mail
85 %(commname)s - committer's name
86 %(diff)s - unified diff of the patch
87 %(fromauth)s - 'From: author\n\n' if different from sender
88 %(longdescr)s - the rest of the patch description, after the first line
89 %(patch)s - patch name
90 %(prefix)s - 'prefix ' string passed on the command line
91 %(shortdescr)s - the first line of the patch description"""
