VERSION
    version 0.10

SYNOPSIS
        use GitStore;

        my $gs = GitStore->new('/path/to/repo');
        $gs->set( 'users/obj.txt', $obj );
        $gs->set( ['config', 'wiki.txt'], { hash_ref => 1 } );
        $gs->commit();
        $gs->set( 'yyy/xxx.log', 'Log me' );
        $gs->discard();
    
        # later or in another pl
        my $val = $gs->get( 'user/obj.txt' ); # $val is the same as $obj
        my $val = $gs->get( 'config/wiki.txt' ); # $val is { hashref => 1 } );
        my $val = $gs->get( ['yyy', 'xxx.log' ] ); # $val is undef since discard

DESCRIPTION
    It is inspired by the Python and Ruby binding. check SEE ALSO

METHODS
  new
        GitStore->new('/path/to/repo');
        GitStore->new( repo => '/path/to/repo', branch => 'mybranch' );
        GitStore->new( repo => '/path/to/repo', author => 'Someone Unknown <unknown\@what.com>' );

    repo
        your git dir (without .git)

    branch
        your branch name, default is 'master'

    author
        It is used in the commit info

  set($path, $val)
        $gs->set( 'yyy/xxx.log', 'Log me' );
        $gs->set( ['config', 'wiki.txt'], { hash_ref => 1 } );
        $gs->set( 'users/obj.txt', $obj );

    Store $val as a $path file in Git

    $path can be String or ArrayRef. Any leading slashes ('/') in the path
    will be stripped, as to make it a valid Git path. The same grooming is
    done for the "get()" and "delete()" methods.

    $val can be String or Ref[HashRef|ArrayRef|Ref[Ref]] or blessed Object

  get($path)
        $gs->get( 'user/obj.txt' );
        $gs->get( ['yyy', 'xxx.log' ] );

    Get $val from the $path file

    $path can be String or ArrayRef

  delete($path)
  remove($path)
    remove $path from Git store

  commit
        $gs->commit();
        $gs->commit('Your Comments Here');

    commit the set changes into Git

  discard
        $gs->discard();

    discard the set changes

  history($path)
    Returns a list of GitStore::Revision objects representing the changes
    brought to the *$path*. The changes are returned in ascending commit
    order.

FAQ
  why the files are not there?
    run

        git checkout

  any example?
        # if you just need a local repo, that's all you need.
        mkdir sandbox
        cd sandbox
        git init
        # use GitStore->new('/path/to/this/sandbox')
        # set something
        git checkout
    
        # follows are for remote git url
        git remote add origin git@github.com:fayland/sandbox2.git
        git push origin master
        # do more GitStore->new('/path/to/this/sandbox') later
        git checkout
        git pull origin master
        git push

KNOWN BUGS
    If all files are deleted from the repository, a 'dummy' file will be
    created to keep Git happy.
