小编Kil*_*yte的帖子

我正在生成Javadocs.现在我想自动将所有库和JDK类链接到该lib或JDK的官方文档.这是可能的,如果是这样,我需要哪个命令行args

我有这个代码用于测试:

import org.scalatest.FlatSpec
import org.scalatest.matchers.Matchers

class TestSpec extends FlatSpec with Matchers {
  "something" should "be something else" in {
    "test" should be ("test")
  }
}

但是我得到这个错误:

Error:(21, 12) overloaded method value should with alternatives:
  (resultOfAfterWordApplication: org.scalatest.verb.ResultOfAfterWordApplication)(implicit fun: (String, String, org.scalatest.verb.ResultOfAfterWordApplication) => Unit)Unit <and>
  (right: => Unit)(implicit fun: org.scalatest.verb.StringVerbBlockRegistration)Unit <and>
  (right: org.scalatest.verb.BehaveWord)(implicit fun: String => org.scalatest.verb.BehaveWord)org.scalatest.verb.BehaveWord <and>
  (right: String)(implicit fun: (String, String, String) => org.scalatest.verb.ResultOfStringPassedToVerb)org.scalatest.verb.ResultOfStringPassedToVerb
 cannot be applied to (org.scalatest.matchers.Matcher[Any])
    "test" should be ("test")
           ^

我正在从他们的网站直接获取代码,并通过maven描述符org.scalatest安装ScalaTest:scalatest_2.10.0:2.0.M5现在似乎是最新的

我正在阅读scala默认库代码,发现这篇文章:

trait TraversableLike[+A, +Repr] extends Any
    with HasNewBuilder[A, Repr]
    with FilterMonadic[A, Repr]
    with TraversableOnce[A]
    with GenTraversableLike[A, Repr]
    with Parallelizable[A, ParIterable[A]]
{
    self =>
    ...
}

究竟是做什么的？

到目前为止我得到了什么：

= button_to 'Delete', "/blog/#{@post.id}", method: 'delete', class: 'btn btn-danger'

但是添加 aconfirm: 'Are you sure'没有效果。而且那条线非常难看，我想缩短它。
