module Decidim
module ContentParsers
# A parser that searches mentions of Proposals in content.
#
# This parser accepts two ways for linking Proposals.
# - Using a standard url starting with http or https.
# - With a word starting with `~` and digits afterwards will be considered a possible mentioned proposal.
# For example `~1234`, but no `~ 1234`.
#
# Also fills a `Metadata#linked_proposals` attribute.
#
# @see BaseParser Examples of how to use a content parser

# Class used as a container for metadata

# @!attribute linked_proposals
# @return [Array] an array of Decidim::Proposals::Proposal mentioned in content
