Text::MicroMason::PostProcess - Apply Filters to All Template Output
Contents
Description
This mixin class adds filtering of all template output to any MicroMason class.
Filter functions can accept the string to be output and return a filtered version:
$mason->post_process( sub {
my $foo = shift;
$foo =~ s/a-Z/A-Z/;
return $foo;
} );
If a filter function has an empty prototype, it's assumed to work on $_:
$mason->post_process( sub () {
s/a-Z/A-Z/
} );
PublicMethodspost_processors()
Gets and sets the functions to be used for output filtering.
Called with no arguments, returns the list of filter functions:
my @functions = $mason->post_processors();
Called with one array-ref argument, sets the list of filter functions:
$mason->post_processors( \@functions );
Called with one or more function-ref arguments, appends to the list:
$mason->post_processors( $filter1, $filter2 );
SupportedAttributes
post_process
Stores a reference to a function or an array of functions to be used:
$mason->{post_process} = $function;
$mason->{post_process} = [ $function1, $function2 ];
You can set this attribute when you create your mason object, or in calls to the compile and execute
methods.
PrivateMethodspost_process()
$mason->post_process( $output ) : $filtered_output
Applies the post-processing filter.

Synopsis
Instead of using this class directly, pass its name to be mixed in:
use Text::MicroMason;
my $mason = Text::MicroMason->new( -PostProcess );
Use the standard compile and execute methods to parse and evaluate templates:
print $mason->compile( text=>$template )->( @%args );
print $mason->execute( text=>$template, @args );
You can define output filters at creation or subsequently:
$mason = Text::MicroMason->new( -PostProcess, post_process => $func );
$mason->post_processors( $func );
$mason->compile( text => $template, post_process => $func );
$mason->execute( text => $template, { post_process => $func }, @args );
