NAME

Text::MicroMason::PostProcess - Apply Filters to All Template Output

SYNOPSIS

Instead of using this class directly, pass its name to be mixed in:

    use Text::MicroMason;
    my $mason = Text::MicroMason->new( -PostProcess );

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 );

Then use the compile and execute methods as you normally would:

    print $mason->execute( text=>$template, 'name'=>'Dave' );

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/
  } );

Public Methods

post_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 );

Supported Attributes

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.
