30 Send a patch or a range of patches by e-mail using the 'smtpserver'
31 configuration option. The From address and the e-mail format are
32 generated from the template file passed as argument to '--template'
33 (defaulting to '.git/patchmail.tmpl' or
34 '~/.stgit/templates/patchmail.tmpl' or or
35 '/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 '--cover' and/or '--edit'
40 options. The first allows the user to specify a file to be used as a
41 template. The latter option will invoke the editor on the specified
42 file (defaulting to '.git/covermail.tmpl' or
43 '~/.stgit/templates/covermail.tmpl' or
44 '/usr/share/stgit/templates/covermail.tmpl').
46 All the subsequent e-mails appear as replies to the first e-mail sent
47 (either the preamble or the first patch). E-mails can be seen as
48 replies to a different e-mail by using the '--refid' option.
50 SMTP authentication is also possible with '--smtp-user' and
51 '--smtp-password' options, also available as configuration settings:
52 'smtpuser' and 'smtppassword'.
54 The template e-mail headers and body must be separated by
55 '%(endofheaders)s' variable, which is replaced by StGIT with
56 additional headers and a blank line. The patch e-mail template accepts
57 the following variables:
59 %(patch)s - patch name
60 %(maintainer)s - 'authname <authemail>' as read from the config file
61 %(shortdescr)s - the first line of the patch description
62 %(longdescr)s - the rest of the patch description, after the first line
63 %(endofheaders)s - delimiter between e-mail headers and body
64 %(diff)s - unified diff of the patch
65 %(diffstat)s - diff statistics
66 %(date)s - current date/time
67 %(version)s - ' version' string passed on the command line (or empty)
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 %(authname)s - author's name
72 %(authemail)s - author's email
73 %(authdate)s - patch creation date
74 %(commname)s - committer's name
75 %(commemail)s - committer's e-mail
77 For the preamble e-mail template, only the %(maintainer)s, %(date)s,
78 %(endofheaders)s, %(version)s, %(patchnr)s, %(totalnr)s and %(number)s
79 variables are supported."""
