Description: Git Pre-Receive Hook to Validate Commits
        ========================================
        
        It is exhausting to edit files again and again to have a consistent style.
        This project provides a Git pre-receive hook to validate pushed commits on
        the Git server side.  The hook avoids all issues by rejecting any commit
        not matching the rules to get in to the repository in the first place.
        
        The pre-receive hook runs some checks on commits on its own, and searches
        for programming language specific syntax checkers on the PATH of the server
        to check changed files with them.  The process is pretty fast, because only
        the added and modified files on the pushed commits are passed to the syntax
        checkers, also in parallel.  It wouldn't slow you down unless your commits
        are touching hundreds of files.
        
        
        Installation
        ------------
        
        It is possible to install the tool with `pip`::
        
            pip install igcommit
        
        Link the `script <igcommit-receive>`_ to ``hooks/pre-receive`` on you Git
        repositories on your Git server::
        
            ln -s igcommit-receive /home/git/repositories/myproject.git/hooks/pre-receive

        Here is an example problem output::
        
            === CheckDuplicateCommitSummaries on CommitList ===

        Configuration
        -------------
        
        The script itself is currently configuration free.  Though, some of the syntax
        checkers called by the script uses or requires configurations.  Those
        configuration files has to be on the top level of the Git repository.

        Pros and Cons of Pre-receive Hook
        ---------------------------------
        
        Continuous Integration Server
            A continuous integration server can run such checks with the many other
            things it is doing.  Moving this job from it has many benefits:
        
            * Synchronous feedback
            * More efficient
            * Disallow any commit violating the rules
        
        Pre-commit Hook
            Even though, pre-receive hook gives later feedback than pre-commit hook,
            it has many advantages over it:
        
            * No client side configuration
            * Plugins has to be installed only once to the Git server
            * Everybody gets the same checks
            * Enforcement, nobody can skip the checks
            * Commit checking (pre-commit hook only gets what is changed in the commit)
        
        IDE Integration
            The same advantages compared to pre-commit hooks applies to IDE
            integration.  Though, IDE integration gives much sooner and nicer feedback,
            so it is still a good idea, even with the pre-receive hook.
        
        
        Dependencies
        ------------
        
        The script has no dependencies on Python 3.4 or above.  It runs on Python 2
        as well with the backport of enum library "enum34".  The script executes
        the validation commands using the shell.  The necessary ones for checked
        repositories need to be installed separately.  See the complete list of
        commands on the `config.py <igcommit/config.py>`_.  The commands which are not
        available on the ``PATH`` is not going to be used.
        
        
        Testing
        -------
        
        I found it useful to check what the script would have complained if it would
        be active on different Git repositories.  You can run a command like this
        to test it on a Git repository against last 50 commits::
        
            git log --reverse --oneline HEAD~50..HEAD |
                sed 's:\([^ ]*\) .*:\1 \1 refs/heads/master:' |
                python ../igcommit/igcommit-receive
