31 Send a patch or a range of patches by e-mail using the 'smtpserver'
32 configuration option. The From address and the e-mail format are
33 generated from the template file passed as argument to '--template'
34 (defaulting to '.git/patchmail.tmpl' or
35 '~/.stgit/templates/patchmail.tmpl' or
36 '/usr/share/stgit/templates/patchmail.tmpl').
38 The To/Cc/Bcc addresses can either be added to the template file or
39 passed via the corresponding command line options. They can be e-mail
40 addresses or aliases which are automatically expanded to the values
41 stored in the [mail "alias"] section of GIT configuration files.
43 A preamble e-mail can be sent using the '--cover' and/or
44 '--edit-cover' options. The first allows the user to specify a file to
45 be used as a template. The latter option will invoke the editor on the
46 specified file (defaulting to '.git/covermail.tmpl' or
47 '~/.stgit/templates/covermail.tmpl' or
48 '/usr/share/stgit/templates/covermail.tmpl').
50 All the subsequent e-mails appear as replies to the first e-mail sent
51 (either the preamble or the first patch). E-mails can be seen as
52 replies to a different e-mail by using the '--refid' option.
54 SMTP authentication is also possible with '--smtp-user' and
55 '--smtp-password' options, also available as configuration settings:
56 'smtpuser' and 'smtppassword'.
58 The patch e-mail template accepts the following variables:
60 %(patch)s - patch name
61 %(sender)s - 'sender' or 'authname <authemail>' as per the config file
62 %(shortdescr)s - the first line of the patch description
63 %(longdescr)s - the rest of the patch description, after the first line
64 %(diff)s - unified diff of the patch
65 %(diffstat)s - diff statistics
66 %(version)s - ' version' string passed on the command line (or empty)
67 %(prefix)s - 'prefix ' string passed on the command line
68 %(patchnr)s - patch number
69 %(totalnr)s - total number of patches to be sent
70 %(number)s - empty if only one patch is sent or ' patchnr/totalnr'
71 %(fromauth)s - 'From: author\\n\\n' if different from sender
72 %(authname)s - author's name
73 %(authemail)s - author's email
74 %(authdate)s - patch creation date
75 %(commname)s - committer's name
76 %(commemail)s - committer's e-mail
78 For the preamble e-mail template, only the %(sender)s, %(version)s,
79 %(patchnr)s, %(totalnr)s and %(number)s variables are supported."""
