#ABSTRACT: Module for managing issues in a git branch within your repository

=head1 DESCRIPTION
|
|
|
|
Git::IssueManager is a Perl Module for using git as an issue store creating a
|
|
B<distributed issue management system>.
|
|
It uses the Git::LowLevel Module to store issues in a B<issue> branch using trees
|
|
and blobs.
|
|
|
|
|
|
=head2 EXAMPLE
|
|
|
|
use Git::IssueManager;
|
|
|
|
my $manager = Git::IssueManager->new(repository=>Git::LowLevel->new(git_dir=> "."));
|
|
if (!$manager->ready)
|
|
{
|
|
print("IssueManager not initialized yet. Please call \"init\" command to do so.");
|
|
exit(-1);
|
|
}
|
|
|
|
my @issues=$manager->list();
|
|
|
|
for my $i (@issues)
|
|
{
|
|
print $i->subject . "\n";
|
|
}
|

=head2 MOTIVATION
|
|
|
|
Issue management is an essential part in modern software engineering. In most cases tools
|
|
like I<jira> or I<github> are used for this task. The central nature of these tools is a large
|
|
disadvantage if you are often on the road. Furthermore if you are using I<git> for version
|
|
control you have everything available for B<distributed issue management>.
