腳註考慮的例子中,我跑在IRB如下:逐字從<a href="http://kramdown.rubyforge.org/syntax.html#footnotes" rel="nofollow">http://kramdown.rubyforge.org/syntax.html#footnotes</a>啓用Kramdown
Kramdown::Document.new('This is some text.[^1]. Other text.[^footnote].').to_html
將返回:
"<p>This is some text.[^1]. Other text.[^footnote].</p>\n"
這似乎表明,腳註Kramdown默認是禁用的。我如何啓用它們?我查看了[選項文檔](http://kramdown.rubyforge.org/options.html),但我沒有看到啓用/禁用那裏列出腳註的選項。
