=head1 NAME
Mason::Filters::Standard - Standard filters
=head1 DESCRIPTION
These filters are automatically composed into
L<Mason::Component|Mason::Component>.
=head1 FILTERS
=over
=item Capture ($ref)
Uses C<< $m->capture >> to capture the content in I<$ref> instead of outputting
it.
% $.Capture(\my $content) {{
<!-- this will end up in $content -->
% }}
... do something with $content
=item CompCall ($path, @args...)
Calls the component with I<path> and I<@args>, just as with C<< $m->scomp >>,
with an additional coderef argument C<yield> that can be invoked to generate
the content. Arguments passed to C<yield> can be accessed inside the content
via C<@_>. This is the replacement for Mason 1's L<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) %>
% }
=item NoBlankLines
Remove lines with only whitespace from content. This
% $.NoBlankLines {{
hello
world
% }}
yields
hello
world
=item Repeat ($count)
Repeat the content block I<$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) {{
<% $i++ %><br>
% }}
=item Tee ($ref)
Uses C<< $m->capture >> to capture the content in I<$ref>, and also output it.
% $.Tee(\my $content) {{
<!-- this will end up in $content and also be output -->
% }}
...
<!-- output content again down here -->
<% $content %>
=item Trim
Remove whitespace from the beginning and end of the content.
