31 Send a patch or a range of patches (defaulting to the applied patches)
32 by e-mail using the 'smtpserver' configuration option. The From
33 address and the e-mail format are generated from the template file
34 passed as argument to '--template' (defaulting to .git/patchmail.tmpl
35 or /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 /usr/share/stgit/templates/covermail.tmpl).
45 All the subsequent e-mails appear as replies to the first e-mail sent
46 (either the preamble or the first patch). E-mails can be seen as
47 replies to a different e-mail by using the '--refid' option.
49 SMTP authentication is also possible with '--smtp-user' and
50 '--smtp-password' options, also available as configuration settings:
51 'smtpuser' and 'smtppassword'.
53 The template e-mail headers and body must be separated by
54 '%(endofheaders)s' variable, which is replaced by StGIT with
55 additional headers and a blank line. The patch e-mail template accepts
56 the following variables:
58 %(patch)s - patch name
59 %(maintainer)s - 'authname <authemail>' as read from the config file
60 %(shortdescr)s - the first line of the patch description
61 %(longdescr)s - the rest of the patch description, after the first line
62 %(endofheaders)s - delimiter between e-mail headers and body
63 %(diff)s - unified diff of the patch
64 %(diffstat)s - diff statistics
65 %(date)s - current date/time
66 %(version)s - ' version' string passed on the command line (or empty)
67 %(patchnr)s - patch number
68 %(totalnr)s - total number of patches to be sent
69 %(number)s - empty if only one patch is sent or ' patchnr/totalnr'
70 %(authname)s - author's name
71 %(authemail)s - author's email
72 %(authdate)s - patch creation date
73 %(commname)s - committer's name
74 %(commemail)s - committer's e-mail
76 For the preamble e-mail template, only the %(maintainer)s, %(date)s,
77 %(endofheaders)s, %(version)s, %(patchnr)s, %(totalnr)s and %(number)s
78 variables are supported."""
