NAME

notice - Breaking-Change Acknowledgement

ABSTRACT

Breaking-Change Acknowledgement Enforcement

SYNOPSIS

package Example;

BEGIN {
$ENV{ACK_NOTICE_EXAMPLE_UNSTABLE} = 1;
}

use notice unstable => {
space => 'Example',
until => '2020-09-01',
notes => 'See https://example.com/latest/release-notes',
};

1;

DESCRIPTION

This package provides a mechanism for enforcing breaking-change
acknowledgements. When configured under a module namespace, a fatal
error (notice) will be thrown prompting the operator to acknowledge the
notice (unless the notice has already been ackowledged). Notices are
acknowledged by setting a predetermined environment variable. The
environment variable always takes the form of
ACK_NOTICE_CLASS_NOTICENAME. The fatal error (notice) is thrown
whenever, the encapsulating package is "used", the notice criteria is
met, and the environment variable is missing. Multiple notices can be
configured and each can have a time-based expiry aftewhich the notice
will never be triggered.

FUNCTIONS

This package implements the following functions:

check

check(ClassName $name, Any %args) : Maybe[Tuple[Str, Str, Str, Str, Str | ArrayRef]]

The check method returns truthy or falsy based upon whether the notice
criteria is met. When met, this function returns details about the
trigger engaged.

},
));

check example #2

# given: synopsis

delete $ENV{ACK_NOTICE_EXAMPLE_UNSTABLE};

notice::check('Example', (
unstable => {
until => '2000-09-01',
notes => 'see changelog',
},
));

check example #3

# given: synopsis

delete $ENV{ACK_NOTICE_EXAMPLE_UNSTABLE};
