NAME

Mason::Filters::Standard - Standard filters

CONTENTS

DESCRIPTION

These filters are automatically composed into Mason::Component.

FILTERS

Capture ($ref) Uses $m->capture to capture the content in $ref instead of outputting it.



    % $.Capture(\my $content) {{
      <!-- this will end up in $content -->
    % }}

    ... do something with $content



CompCall ($path, @args...) Calls the component with path and @args, just as with $m->scomp, with an additional coderef argument yield that can be invoked to generate the content. Arguments passed to yield can be accessed inside the content via @_. This is the replacement for Mason 1’s Components With Content <http://search.cpan.org/perldoc?HTML::Mason::Devel#Component_Calls_with_Content>.



  In index.mc:
    % $.CompCall (list_items.mi, items => \@items) {{
    <li><% $_[0] %></li>
    % }}

  In list_items.mi:
    <%class>
    has items;
    has yield;
    </%class>

    % foreach my $item (@{$.items}) {
    <% $.yield->($item) %>
    % }



NoBlankLines Remove lines with only whitespace from content. This



    % $.NoBlankLines {{

    hello


    world   
    % }}



yields



    hello
    world



Repeat ($count) Repeat the content block $count times. Note that the block is re-executed each time, which may result in different content.



    <!-- Prints 1 to 5 -->
    % my $i = 1;
    % $.Repeat(5) {{
       <% $i++ %><br>
    % }}



Tee ($ref) Uses $m->capture to capture the content in $ref, and also output it.



    % $.Tee(\my $content) {{
      <!-- this will end up in $content and also be output -->
    % }}

    ...

    <!-- output content again down here -->
    <% $content %>



Trim Remove whitespace from the beginning and end of the content.
