%= scalar localtime
% end
DESCRIPTION
This plugin provides the functionality to easily memorize a portion of a template, to prevent re-evaluation. This may be useful when a portion of your response is expensive to generate but changes rarely (a menu for example).
The memorize
helper derives from the helper that was removed from Mojolicious
at version 4.0, with two major changes. The underlying plugin object is returned when no arguments are passed and the system is resiliant against time jumps.
HELPERS
memorize( [$name,] [$args,] [$template_block] )
-
When called with arguments, this helper wraps the functionality of the
memorize
method below. See its documentation for usage.When called without arguments, the plugin object is returned, allowing the use of other plugin methods or access to the plugin's cache.
ATTRIBUTES
cache
-
A hash reference containing the memorized template content and other data.
METHODS
expire( $name )
-
This method allows for manually expiring a memorized template block. This may useful if the template is set to never expire or when the underlying content is known to have changed.
This is an example of the utility of having access to the underlying hash. In the original implementation of the core helper, this access was not available.
memorize( [$name,] [$args,] $template_block )
-
This method behaves as the old helper did. It takes as many as three arguments, the final of which must be a template block (see "Blocks" in Mojolicious::Lite) to be memorized. The first argument may be a string which is the name (key) of the memorized template (used for later access); if this is not provided one will be generated. A hashref may also be passed in which is used for additional arguments.
As of this writing, the only available argument are
duration
andexpires
. Theduration
key specifies the number of seconds that the template should be memorized, while theexpires
key specifies a time (epoch seconds) after which the template should be re-evaluated.duration
is the recommened usage,expires
is provided for historical reasons, and is implemented usingduration
. If both are provided,duration
is used.Note that either key may be set to zero to prevent timed expiration.
register
-
This method is called upon loading the plugin and probably is not useful for other purposes.
