module Primer
# Conditionally renders a `Primer::BaseComponent` around the given content. If the given condition
# is true, a `Primer::BaseComponent` will render around the content. If the condition is false, only
# the content is rendered.
#
# @example True conditional
# <%# condition is true, so content will be wrapped in a <span> tag
# <%= render Primer::ConditionalWrapper.new(condition: true, tag: :span, class: "foobar")) do %>
# <%# also rendered %>
# <p class="bazboo">Some text</p>
# <% end %>
#
# @example False conditional
# <%# condition is false so no <span> tag will render around the content (i.e. the <p> tag)
# <%= render(Primer::ConditionalWrapper.new(condition: false, tag: :span, class: "foobar")) do %>
# <%# this content will be rendered %>
# <p class="bazboo">Some text</p>
# <% end %>
#
# @param condition [Boolean] Whether or not to wrap the content in a `Primer::BaseComponent`.
# @param base_component_arguments [Hash] The arguments to pass to `Primer::BaseComponent`.
