30 Send a patch or a range of patches (defaulting to the applied patches)
31 by e-mail using the 'smtpserver' configuration option. The From
32 address and the e-mail format are generated from the template file
33 passed as argument to '--template' (defaulting to .git/patchmail.tmpl
34 or /usr/share/stgit/templates/patchmail.tmpl). The To/Cc/Bcc addresses
35 can either be added to the template file or passed via the
36 corresponding command line options.
38 A preamble e-mail can be sent using the '--cover' and/or '--edit'
39 options. The first allows the user to specify a file to be used as a
40 template. The latter option will invoke the editor on the specified
41 file (defaulting to .git/covermail.tmpl or
42 /usr/share/stgit/templates/covermail.tmpl).
44 All the subsequent e-mails appear as replies to the first e-mail sent
45 (either the preamble or the first patch). E-mails can be seen as
46 replies to a different e-mail by using the '--refid' option.
48 SMTP authentication is also possible with '--smtp-user' and
49 '--smtp-password' options, also available as configuration settings:
50 'smtpuser' and 'smtppassword'.
52 The template e-mail headers and body must be separated by
53 '%(endofheaders)s' variable, which is replaced by StGIT with
54 additional headers and a blank line. The patch e-mail template accepts
55 the following variables:
57 %(patch)s - patch name
58 %(maintainer)s - 'authname <authemail>' as read from the config file
59 %(shortdescr)s - the first line of the patch description
60 %(longdescr)s - the rest of the patch description, after the first line
61 %(endofheaders)s - delimiter between e-mail headers and body
62 %(diff)s - unified diff of the patch
63 %(diffstat)s - diff statistics
64 %(date)s - current date/time
65 %(version)s - ' version' string passed on the command line (or empty)
66 %(patchnr)s - patch number
67 %(totalnr)s - total number of patches to be sent
68 %(number)s - empty if only one patch is sent or ' patchnr/totalnr'
69 %(authname)s - author's name
70 %(authemail)s - author's email
71 %(authdate)s - patch creation date
72 %(commname)s - committer's name
73 %(commemail)s - committer's e-mail
75 For the preamble e-mail template, only the %(maintainer)s, %(date)s,
76 %(endofheaders)s, %(version)s, %(patchnr)s, %(totalnr)s and %(number)s
77 variables are supported."""
