=head1 NAME

Dist::Zilla::Plugin::Bugtracker - Automatically sets the bugtracker URL and mailto

=head1 VERSION

version 1.111080

=head1 SYNOPSIS

In C<dist.ini>:

    [Bugtracker]

=head1 DESCRIPTION

This plugin sets the distribution's bugtracker URL and possibly the email
address as metadata. You can set the C<web> and the C<mailto> values
independently in the plugin configuration.

=head1 METHODS

=head2 web

This is the bugtracker URL. It defaults to the CPAN RT URL, so it equivalent to:

    [Bugtracker]
    web = http://rt.cpan.org/Public/Dist/Display.html?Name=%s

See C<interpolate()> for more information.

=head2 mailto

This is the optional email address to which bug reports can be sent. If the
CPAN RT bugtracker is used, the email address defaults to C<bug-%l at
rt.cpan.org> - see C<interpolate()> for what this means.

If a different bugtracker URL is used, the email address is only included in
the metadata if it is explicitly given.

In the following examples, assume that the distribution is called C<Foo-Bar>.

Example 1:

    [Bugtracker]

will produce the defaults:

    web:    http://rt.cpan.org/Public/Dist/Display.html?Name=Foo-Bar
    mailto: bug-foo-bar at rt.cpan.org

Example 2:

To suppress the C<mailto> from example 1, use:

    [Bugtracker]
    mailto =

Example 3:

    [Bugtracker]
    web = http://github.com/me/%s/issues

will only produce a C<web> entry, but not a C<mailto> entry:

    web: http://github.com/me/Foo-Bar/issues

Example 4:

    [Bugtracker]
    mailto = me@example.org

will produce:

    web:    http://rt.cpan.org/Public/Dist/Display.html?Name=Foo-Bar
    mailto: me@example.org

Example 5:

    [Bugtracker]
    web = http://github.com/me/%s/issues
    mailto = bug-%U@example.org

will only produce a C<web> entry, but not a C<mailto> entry:

    web:    http://github.com/me/Foo-Bar/issues
    mailto: bug-FOO-BAR@example.org

See
L<CPAN::Meta::Spec|http://search.cpan.org/dist/CPAN-Meta/lib/CPAN/Meta/Spec.pm#resources>
for more information.

=head2 interpolate

Both the C<web> and C<mailto> strings are interpolated as follows:

    %s  The distribution name as is (e.g., 'Foo-Bar')
    %l  The distribution name in lowercase (e.g., 'foo-bar')
    %U  The distribution name in uppercase (e.g., 'FOO-BAR')
    %%  A literal '%' sign

=head2 metadata

Sets the bugtracker URL and possibly email address in the distribution's metadata.
