=head1 METHODS

=cut

=head2 index

=cut

use IO::Capture::Stdout;
use File::Slurp qw(slurp);

=head2 run_gitweb

The main shim around C<gitweb.pm>.

=cut

sub run_gitweb {
  my ( $self, $c ) = @_;

  # XXX A slippery slope to be sure.
  if($c->req->param('a')) {
    my $capture = IO::Capture::Stdout->new();

    my $output = join '', $capture->read;
    $c->stash->{gitweb_output} = $output;
    $c->stash->{template} = 'gitweb.tt2';
  }
}

=head2 index

Provides the project listing.

=cut

  my ( $self, $c ) = @_;

  # Leave actions up to gitweb at this point.
  return $self->run_gitweb($c)

    searchtext => $c->req->param('searchtext') || '',
    projects   => $list,

=head2 blob

The blob action i.e the contents of a file.

=cut

sub blob : Local {
  my ( $self, $c ) = @_;

  $c->stash(
    blob   => $c->model('GPP')->get_object($c->req->param('h'))->content,

=head2 reflog

Expose the local reflog. This may go away.

=cut

sub reflog : Local {
  my ( $self, $c ) = @_;

  my @log = $c->model('Git')->reflog(
      '--since=yesterday'
  );

  $c->stash(

Exposes a given commit. Probably too simple currently.

Populate the header and footer. Perhaps not the best location.
