小编Scá*_*cán的帖子

因为我对HTML标签感到恼火,所以我开始将我的项目转换为HAML,因为它的结构更好.我很高兴安装提供了html2haml帮助我的工具.

虽然在语法上是正确的,处理文件给我一个奇怪的错误,我不太明白:

/stories/_story.html.haml:28: syntax error, unexpected keyword_ensure, expecting keyword_end
...:Util.html_safe(_erbout);ensure;@haml_buffer = @haml_buffer....
...                               ^
/stories/_story.html.haml:31: syntax error, unexpected $end, expecting keyword_end

我的haml源只有27行,因为我对此很新,我不知道它出错了...这里是代码:

%h1= story.title
%center
  %i
    by #{link_to story.user.name, story.user}
#story-short= story.short_desc
- if logged_in? and @current_user.id == story.user_id
  .list-buttons
    %center
      = link_to 'Edit', edit_story_path(story)
      |
      \#{link_to 'Delete', story, :method => 'delete', :confirm => 'Are you really sure?'}
#story-body
  - story.body.split("\n").each do |line|
  - if line.strip.empty?
    %hr/
  - else
    %p= line.strip
#comments
  %p{:onclick => "$('#comments').find('dl').slideToggle();"} Comments to this …

好吧,简单的问题:我有一个扩展的单例对象,scala.swing.Panel我希望它能通过简单的鼠标点击做出反应.但是......好吧,它不起作用.由于Scala是一种新语言,因此找到特定问题的信息并不容易.也许你可以帮忙:

import scala.swing._
import scala.swing.event._
import java.awt.{Graphics2D, Color}

object GamePanel extends Panel {
  val map: TileMap = new TileMap(10, 10)({
    (x, y) =>
      if (x == y) new Wood
      else if (x == 5) new Water
      else new Grass
  })

  reactions += {
    case MouseClicked(src, pt, mod, clicks, pops) => {
      selectedTile = (pt.x / map.tw, pt.y / map.th)
      println("Clicked")
      repaint
    }
  }

  var selectedTile = (0, 0)

  override def paint(g: Graphics2D) = {
    map.draw(g)
    g.setColor(Color.red)
    g.drawRect(selectedTile._1 - …
