Hello,
I have a script which creates a certain text file.
Whenever I call it, I need to recreate this file, because I have no need in the previous content.
So I thought to remove the file every time I call the script, and that way I am sure that the previous content will not interrupt me.... (2 Replies)

Mason::Filters::Standard(3pm) User Contributed Perl Documentation Mason::Filters::Standard(3pm)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 <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.
