"""Example post-receive hook based on git-multimail.
The simplest way to use git-multimail is to use the script
git_multimail.py directly as a post-receive hook, and to configure it
using Git's configuration files and command-line parameters. You can
also write your own Python wrapper for more advanced configurability,
using git_multimail.py as a Python module.
This script is a simple example of such a post-receive hook. It is
intended to be customized before use; see the comments in the script
to help you get started.
Using git-multimail as a Python module as done here provides more
flexibility. It has the following advantages:
* The tool's behavior can be customized using arbitrary Python code,
without having to edit git_multimail.py.
* Configuration settings can be read from other sources; for example,
user names and email addresses could be read from LDAP or from a
database. Or the settings can even be hardcoded in the importing
Python script, if this is preferred.
This script is a very basic example of how to use git_multimail.py as
a module. The comments below explain some of the points at which the
script's behavior could be changed or customized.
"""
import sys
import os
# If necessary, add the path to the directory containing
# git_multimail.py to the Python path as follows. (This is not
# necessary if git_multimail.py is in the same directory as this
# script):
#LIBDIR = 'path/to/directory/containing/module'
#sys.path.insert(0, LIBDIR)
import git_multimail
# It is possible to modify the output templates here; e.g.:
#git_multimail.FOOTER_TEMPLATE = """\
#
#-- \n\
#This email was generated by the wonderful git-multimail tool.
#"""
# Specify which "git config" section contains the configuration for
# git-multimail:
config = git_multimail.Config('multimailhook')
# Select the type of environment:
try:
environment = git_multimail.GenericEnvironment(config=config)
#environment = git_multimail.GitoliteEnvironment(config=config)
except git_multimail.ConfigurationException:
sys.stderr.write('*** %s\n' % sys.exc_info()[1])
sys.exit(1)
# Choose the method of sending emails based on the git config:
mailer = git_multimail.choose_mailer(config, environment)
# Alternatively, you may hardcode the mailer using code like one of
# the following:
# Use "/usr/sbin/sendmail -oi -t" to send emails. The envelopesender
# argument is optional:
#mailer = git_multimail.SendMailer(
# command=['/usr/sbin/sendmail', '-oi', '-t'],
# envelopesender='git-repo@example.com',
# )
# Use Python's smtplib to send emails. Both arguments are required.
#mailer = git_multimail.SMTPMailer(
# envelopesender='git-repo@example.com',
# # The smtpserver argument can also include a port number; e.g.,
# # smtpserver='mail.example.com:25'
# smtpserver='mail.example.com',
# )
# OutputMailer is intended only for testing; it writes the emails to
# the specified file stream.
#mailer = git_multimail.OutputMailer(sys.stdout)
# Read changes from stdin and send notification emails:
git_multimail.run_as_post_receive_hook(environment, mailer)
