当我将字符串传递给kramdown时，我似乎无法使列表函数正常工作：
例如，这是我的文字：
email_body = "Hi, Tim! Hopefully you get this. I just got your email address. \n\n My email is x@xcom. \n\n For example, you could tell me: * 3 hours from now\n * 2 days from now at 5pm\n * Wednesday afternoon\n"
email_body = Kramdown::Document.new(email_body).to_html
email_body = "<p>Hi, Tim! Hopefully you get this. I just got your email address. \n\n My email is x@xcom. \n\n For example, you could tell me: * 3 hours from now\n * 2 days from now at 5pm\n * Wednesday afternoon\n</p>"
我无法将其转换为基于Markdown / kramdown的正确HTML（例如插入<ul>和正确的换行符。

如果我们将您的正文文本格式化为heredoc可能会更容易：
email_body = <<BODY
Hi, Tim! Hopefully you get this. I just got your email address.
My email is x@xcom.
For example, you could tell me: * 3 hours from now
* 2 days from now at 5pm
* Wednesday afternoon
BODY
请注意，您的每个后续行都以空格开头？ Normal paragraphs should not be indented。同样要开始一个列表，你需要一个空白行，比如开始新的段落。因此，作为一个heredoc你真正想要的是：
email_body = <<BODY
Hi, Tim! Hopefully you get this. I just got your email address.
My email is x@xcom.
For example, you could tell me:
* 3 hours from now
* 2 days from now at 5pm
* Wednesday afternoon
BODY
或者作为一行：email_body_single_line = "Hi, Tim! Hopefully you get this. I just got your email address.\n\nMy email is x@xcom.\n\nFor example, you could tell me:\n\n* 3 hours from now\n* 2 days from now at 5pm\n* Wednesday afternoon\n"
然后你接近预期的输出：
output = Kramdown::Document.new(email_body).to_html
=> "<p>Hi, Tim! Hopefully you get this. I just got your email address.</p>\n\n<p>My email is x@xcom.</p>\n\n<p>For example, you could tell me:</p>\n\n<ul>\n <li>3 hours from now</li>\n <li>2 days from now at 5pm</li>\n <li>Wednesday afternoon</li>\n</ul>\n"
