NAME

Git::Repository::Log::Iterator - Split a git log stream into records

SYNOPSIS

    use Git::Repository::Log::Iterator;
    # use a default Git::Repository context
    my $iter = Git::Repository::Log::Iterator->new('HEAD~10..');
    # or provide an existing instance
    my $iter = Git::Repository::Log::Iterator->new( $r, 'HEAD~10..' );
    # get the next log record
    while ( my $log = $iter->next ) {
        ...;
    }

DESCRIPTION

"Git::Repository::Log::Iterator" initiates a git log command from a list of paramaters and parses its output to produce Git::Repository::Log objects represening each log item.

METHODS

new

    my $iter = Git::Repository::Log::Iterator->new( @args );

Create a new git log stream from the parameter list in @args and return a iterator on it.

new() will happily accept any parameters, but note that "Git::Repository::Log::Iterator" expects the output to look like that of "--pretty=raw", and so will force the the "--pretty" option (in case "format.pretty" is defined in the Git configuration). It will also forcibly remove colored output (using "--color=never").

Extra output (like patches) will be stored in the "extra" parameter of the Git::Repository::Log object. Decorations will be lost.

When unsupported options are recognized in the parameter list, new() will croak() with a message advising to use "run( 'log' => ... )" to parse the output yourself.

The object is really a blessed hash reference, with only two keys:

cmd: The Git::Repository::Command object running the actual git log command. It might not be defined in some cases (see below "new_from_fh" and "new_from_file").
fh: The filehandle from which the output of git log is actually read. This is the only attribute needed to run the "next" method.

new_from_fh

This constructor makes it possible to provide the filehandle directly.

The "cmd" key is not defined when using this constructor.

new_from_file

This constructor makes it possible to provide a filename that will be open()ed to produce a filehandle to read the log stream from.

The "cmd" key is not defined when using this constructor.

    my $log = $iter->next;

Return the next log item as a Git::Repository::Log object, or nothing if the stream has ended.
