module GitlabMarkdownHelper include Gitlab::Markdown # Use this in places where you would normally use link_to(gfm(...), ...). # # It solves a problem occurring with nested links (i.e. # "outer text gfm ref more outer text"). This will not be # interpreted as intended. Browsers will parse something like # "outer text gfm ref more outer text" (notice the last part is # not linked any more). link_to_gfm corrects that. It wraps all parts to # explicitly produce the correct linking behavior (i.e. # "outer text gfm ref more outer text"). def link_to_gfm(body, url, html_options = {}) return "" if body.blank? escaped_body = if body =~ /^\.*?}m) do |match| "#{match}#{link_to("", url, html_options)[0..-5]}" # "".length +1 end link_to(gfm_body.html_safe, url, html_options) end def markdown(text) unless @markdown gitlab_renderer = Redcarpet::Render::GitlabHTML.new(self, # see https://github.com/vmg/redcarpet#darling-i-packed-you-a-couple-renderers-for-lunch- filter_html: true, with_toc_data: true, hard_wrap: true) @markdown = Redcarpet::Markdown.new(gitlab_renderer, # see https://github.com/vmg/redcarpet#and-its-like-really-simple-to-use no_intra_emphasis: true, tables: true, fenced_code_blocks: true, autolink: true, strikethrough: true, lax_html_blocks: true, space_after_headers: true, superscript: true) end @markdown.render(text).html_safe end end
