28 help = 'Send a patch or series of patches by e-mail'
29 usage = [' [options] [<patch1>] [<patch2>] [<patch3>..<patch4>]']
31 Send a patch or a range of patches by e-mail using the SMTP server
32 specified by the 'stgit.smtpserver' configuration option, or the
33 '--smtp-server' command line option. This option can also be an
34 absolute path to 'sendmail' followed by command line arguments.
36 The From address and the e-mail format are generated from the template
37 file passed as argument to '--template' (defaulting to
38 '.git/patchmail.tmpl' or '~/.stgit/templates/patchmail.tmpl' or
39 '/usr/share/stgit/templates/patchmail.tmpl'). A patch can be sent as
40 attachment using the --attach option in which case the
41 'mailattch.tmpl' template will be used instead of 'patchmail.tmpl'.
43 The To/Cc/Bcc addresses can either be added to the template file or
44 passed via the corresponding command line options. They can be e-mail
45 addresses or aliases which are automatically expanded to the values
46 stored in the [mail "alias"] section of GIT configuration files.
48 A preamble e-mail can be sent using the '--cover' and/or
49 '--edit-cover' options. The first allows the user to specify a file to
50 be used as a template. The latter option will invoke the editor on the
51 specified file (defaulting to '.git/covermail.tmpl' or
52 '~/.stgit/templates/covermail.tmpl' or
53 '/usr/share/stgit/templates/covermail.tmpl').
55 All the subsequent e-mails appear as replies to the first e-mail sent
56 (either the preamble or the first patch). E-mails can be seen as
57 replies to a different e-mail by using the '--refid' option.
59 SMTP authentication is also possible with '--smtp-user' and
60 '--smtp-password' options, also available as configuration settings:
61 'smtpuser' and 'smtppassword'. TLS encryption can be enabled by
62 '--smtp-tls' option and 'smtptls' setting.
64 The following variables are accepted by both the preamble and the
65 patch e-mail templates:
67 %(diffstat)s - diff statistics
68 %(number)s - empty if only one patch is sent or ' patchnr/totalnr'
69 %(patchnr)s - patch number
70 %(sender)s - 'sender' or 'authname <authemail>' as per the config file
71 %(totalnr)s - total number of patches to be sent
72 %(version)s - ' version' string passed on the command line (or empty)
74 In addition to the common variables, the preamble e-mail template
75 accepts the following:
77 %(shortlog)s - first line of each patch description, listed by author
79 In addition to the common variables, the patch e-mail template accepts
82 %(authdate)s - patch creation date
83 %(authemail)s - author's email
84 %(authname)s - author's name
85 %(commemail)s - committer's e-mail
86 %(commname)s - committer's name
87 %(diff)s - unified diff of the patch
88 %(fromauth)s - 'From: author\n\n' if different from sender
89 %(longdescr)s - the rest of the patch description, after the first line
90 %(patch)s - patch name
91 %(prefix)s - 'prefix ' string passed on the command line
92 %(shortdescr)s - the first line of the patch description"""
