# Filters the content in the given block and outputs it. This function
# does not return anything; instead, the filtered contents is directly
# appended to the output buffer (`_erbout`).
#
# This function has been tested with ERB and Haml. Other filters may not
# work correctly.
#
# @example Running a filter on a part of an item or layout
#
# <p>Lorem ipsum dolor sit amet...</p>
# <% filter :rubypants do %>
# <p>Consectetur adipisicing elit...</p>
# <% end %>
#
# @param [Symbol] filter_name The name of the filter to run on the
# contents of the block
#
# @param [Hash] argument Arguments to pass to the filter
#
# @return [void]

# Find filter

# Filter captured data
