VERSION

       version 0.90

SYNOPSIS

           use Git::Raw;

           # open the Git repository at $path
           my $repo = Git::Raw::Repository -> open($path);

           my $commit1 = Git::Raw::Commit -> lookup($repo,
             '4a202b346bb0fb0db7eff3cffeb3c70babbd2045');

           my $commit2 = Git::Raw::Commit -> lookup($repo,
             '5b5b025afb0b4c913b4c338a42934a3863bf3644');

           if (Git::Raw::Graph -> is_descendant_of($repo, $commit1, $commit2)) {
             print $commit1 -> id, ' is a descendant of ', $commit2 -> id, "\n";
           } else {
             print $commit1 -> id, ' is a not descendant of ', $commit2 -> id, "\n";
           }

DESCRIPTION

       WARNING: The API of this module is unstable and may change without warning (any change
       will be appropriately documented in the changelog).

   ahead( $repo, $local, $upstream )
       Get the commits $local is ahead of $upstream. $local and $upstream should be peelable to a
       Git::Raw::Commit object, that is, it should be a Git::Raw::Commit or Git::Raw::Reference
       object, or alternatively a commit id or commit id prefix. This method returns a list of
       Git::Raw::Commit objects, sorted in topological order.

   behind( $repo, $local, $upstream )
       Get the commits $local is behind $upstream. $local and $upstream should be peelable to a
       Git::Raw::Commit object, that is, it should be a Git::Raw::Commit or Git::Raw::Reference
       object, or alternatively a commit id or commit id prefix. This method returns a list of
       Git::Raw::Commit objects, sorted in topological order.

   ahead_behind( $repo, $local, $upstream )
       Get the unique commits between $local and $upstream. $local and $upstream should be
       peelable to a Git::Raw::Commit object, that is, it should be a Git::Raw::Commit or
       Git::Raw::Reference object, or alternatively a commit id or commit id prefix. This method
       returns a hash reference with optional members "ahead" and "behind", each an array of
       Git::Raw::Commit objects, sorted in topological order.

   is_descendant_of( $repo, $commitish, $ancestor )
       Determine if $commitish is the descendant of $ancestor. $commitish and $ancestor should be
       peelable to a Git::Raw::Commit object, that is, it should be a Git::Raw::Commit or
       Git::Raw::Reference object, or alternatively a commit id or commit id prefix.
