stg-mail - Send a patch or series of patches by e-mail


stg mail  [options] [--] [<patch1>] [<patch2>] [<patch3>..<patch4>]


Send a patch or a range of patches by e-mail using the SMTP server specified by the stgit.smtpserver configuration option, or the --smtp-server command line option. This option can also be an absolute path to sendmail followed by command line arguments.

The From address and the e-mail format are generated from the template file passed as argument to --template (defaulting to .git/patchmail.tmpl or ~/.stgit/templates/patchmail.tmpl or /usr/share/stgit/templates/patchmail.tmpl). A patch can be sent as attachment using the --attach option in which case the mailattch.tmpl template will be used instead of patchmail.tmpl.

The To/Cc/Bcc addresses can either be added to the template file or passed via the corresponding command line options. They can be e-mail addresses or aliases which are automatically expanded to the values stored in the [mail "alias"] section of GIT configuration files.

A preamble e-mail can be sent using the --cover and/or --edit-cover options. The first allows the user to specify a file to be used as a template. The latter option will invoke the editor on the specified file (defaulting to .git/covermail.tmpl or ~/.stgit/templates/covermail.tmpl or /usr/share/stgit/templates/covermail.tmpl).

All the subsequent e-mails appear as replies to the first e-mail sent (either the preamble or the first patch). E-mails can be seen as replies to a different e-mail by using the --in-reply-to option.

SMTP authentication is also possible with --smtp-user and --smtp-password options, also available as configuration settings: smtpuser and smtppassword. TLS encryption can be enabled by --smtp-tls option and smtptls setting.

The following variables are accepted by both the preamble and the patch e-mail templates:

%(diffstat)s     - diff statistics
%(number)s       - empty if only one patch is sent or 'patchnr/totalnr'
%(snumber)s      - stripped version of '%(number)s'
%(nspace)s       - ' ' if %(number)s is non-empty, otherwise empty string
%(patchnr)s      - patch number
%(sender)s       - 'sender'  or 'authname <authemail>' as per the config file
%(totalnr)s      - total number of patches to be sent
%(version)s      - 'version' string passed on the command line (or empty)
%(vspace)s       - ' ' if %(version)s is non-empty, otherwise empty string

In addition to the common variables, the preamble e-mail template accepts the following:

%(shortlog)s     - first line of each patch description, listed by author

In addition to the common variables, the patch e-mail template accepts the following:

%(authdate)s     - patch creation date
%(authemail)s    - author's email
%(authname)s     - author's name
%(commemail)s    - committer's e-mail
%(commname)s     - committer's name
%(diff)s         - unified diff of the patch
%(fromauth)s     - 'From: author\n\n' if different from sender
%(longdescr)s    - the rest of the patch description, after the first line
%(patch)s        - patch name
%(prefix)s       - 'prefix' string passed on the command line
%(pspace)s       - ' ' if %(prefix)s is non-empty, otherwise empty string
%(shortdescr)s   - the first line of the patch description
