You can customize these template strings +without changing the script itself, by defining a Python wrapper +around it. The python wrapper should ``import git_multimail`` and then +override the ``git_multimail.*`` strings like this:: + + import sys # needed for sys.argv + + # Import and customize git_multimail: + import git_multimail + git_multimail.REVISION_INTRO_TEMPLATE = """...""" + git_multimail.COMBINED_INTRO_TEMPLATE = git_multimail.REVISION_INTRO_TEMPLATE + + # start git_multimail itself: + git_multimail.main(sys.argv[1:]) + +The template strings can use any value already used in the existing +templates (read the source code). + +Using HTML in template strings +------------------------------ + +If ``multimailhook.commitEmailFormat`` is set to HTML, then +git-multimail will generate HTML emails for commit notifications. The +log and diff will be formatted automatically by git-multimail. By +default, any HTML special character in the templates will be escaped. + +To use HTML formatting in the introduction of the email, set +``multimailhook.htmlInIntro`` to ``true``. Then, the template can +contain any HTML tags, that will be sent as-is in the email. For +example, to add some formatting and a link to the online commit, use +a format like:: + + git_multimail.REVISION_INTRO_TEMPLATE = """\ + <span style="color:#808080">This is an automated email from the git hooks/post-receive script.</span><br /><br /> + + <strong>%(pusher)s</strong> pushed a commit to %(refname_type)s %(short_refname)s + in repository %(repo_shortname)s.<br /> + + <a href="https://github.com/git-multimail/git-multimail/commit/%(newrev)s">View on GitHub</a>. + """ + +Note that the values expanded from ``%(variable)s`` in the format +strings will still be escaped. + +For a less flexible but easier to set up way to add a link to commit +emails, see ``multimailhook.commitBrowseURL``. + +Similarly, one can set ``multimailhook.htmlInFooter`` and override any +of the ``*_FOOTER*`` template strings. |
