NAME

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

CONTENTS

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 evalute 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 );



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.

    Private Methods

post_process()


  $mason->post_process( $output ) : $filtered_output



Applies the post-processing filter.
