NAME

Mason::Filters::Standard - Standard filters

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.

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.
