Question

我试图将链接的脚注用于工作，但不知何故Redcarpet根本没有认识到我传递给初始化器的footnote扩展。我正在运行Redcarpet版本3.3.4，它应该将脚注功能合并到master中，如这些帖子中所述：Post 1

客户渲染器 class CustomMarkdownParser＆lt;隆重的接待::渲染HTML ::

    include ActionView::Helpers::UrlHelper
    include ActionView::Helpers::AssetTagHelper
    include AbstractController::Rendering

    def block_code(code, language)
        Pygments.highlight(code, lexer: language)
    end

    def parse_media_link(link)
    end


    def image(link, title, alt_text)
    end

    def link(link, title, content)
    end

    #def footnote_def(content, number)
    #end

    #def footnote_ref(number)
    #end
end

def md_parser(content)
    puts "Parsing Markdown"
    renderer = CustomMarkdownParser.new(
            hard_wrap: true,
            filter_html: true,
            with_toc_data: true)

    options ={

    }

    markdown = Redcarpet::Markdown.new(renderer,
                                       autolink: true, # detect links and wrap them in link tags
                                       no_intra_emphasis: true, # ensures _ inside words are not repolaced with <em> tags
                                       disable_indented_code_blocks: true, # does not convert lines prefixed with 4 spaces
                                       fenced_code_blocks: true,
                                       lax_spacing: true,
                                       strikethrough: true,
                                       footnotes: true,
                                       superscript: true,
                                       tables: true,
                                       underline: true
    )

    markdown.render(content).html_safe
end

我查看了宝石的代码，它列出了以下扩展名：

EXTENSION_MAP = { # old name => new name :autolink => :autolink, :fenced_code => :fenced_code_blocks, :filter_html => :filter_html, :hard_wrap => :hard_wrap, :prettify => :prettify, :lax_htmlblock => :lax_spacing, :no_image => :no_images, :no_intraemphasis => :no_intra_emphasis, :no_links => :no_links, :filter_styles => :no_styles, :safelink => :safe_links_only, :space_header => :space_after_headers, :strikethrough => :strikethrough, :tables => :tables, :generate_toc => :with_toc_data, :xhtml => :xhtml, # old names with no new mapping :gh_blockcode => nil, :no_tables => nil, :smart => nil, :strict => nil }

我不确定为什么不包括脚注。我收到的输出是这样的（读取^作为上标，结束方括号也是上标的）：大西洋[^ 1]， [^ 1]这是脚注

Answer 1

在自定义渲染器中，您将覆盖处理脚注的方法，因此它们不会执行任何操作。只需删除这些方法（footnote_def和footnote_ref）并允许原始文件运行。

此外，脚注定义的语法需要一个您似乎缺少的冒号：

[^1]: This is the footnote

Redcarpet脚注扩展无法正常工作
