如何在iTerm2中关闭自动换行？是否有特定命令要执行此操作或在首选项中执行此操作？我试图避免文本运行到下一行.我宁愿一边滚动.

我正在使用Sublime Text 2.当我在HTML文件上时.如果我调整窗口大小.最后的代码转移到下一行.我如何阻止这种情况发生？我希望代码继续向前,所以我将不得不左右滚动以查看代码的其余部分,而不是转移到下一行.

我已经截取屏幕截图以更好地说明我所指的内容.

窗口大小调整后.注意数字线？我怎么阻止它？我宁愿向右滚动以查看代码的其余部分,而不是让代码跳转到下一行.

我注意到这只发生在HTML文件中.

我刚开始学习Swift.我创建了一个游戏项目,并出现了一个模板.我没有对代码做任何事情.我试图运行该项目但是弹出了编译器错误.

我要去一个教程,所以它可能是我的环境有问题,或者这本书已经过时了.

Swift编译错误:'Double'不能转换为CGFloat

import SpriteKit

class GameScene: SKScene {
    override func didMoveToView(view: SKView) {
        /* Setup your scene here */
        let myLabel = SKLabelNode(fontNamed:"Chalkduster")
        myLabel.text = "Hello, World!";
        myLabel.fontSize = 65;
        myLabel.position = CGPoint(x:CGRectGetMidX(self.frame), y:CGRectGetMidY(self.frame));

        self.addChild(myLabel)
    }

    override func mouseDown(theEvent: NSEvent) {
        /* Called when a mouse click occurs */

        let location = theEvent.locationInNode(self)

        let sprite = SKSpriteNode(imageNamed:"Spaceship")
        sprite.position = location;
        sprite.setScale(0.5)

        let action = SKAction.rotateByAngle(M_PI, duration:1)
        sprite.runAction(SKAction.repeatActionForever(action))

        self.addChild(sprite)
    }

    override func update(currentTime: CFTimeInterval) {
        /* Called before each frame …

我已经下载了Zurb Foundation图标字体文件http://zurb.com/playground/foundation-icon-fonts-3

我解压缩它们并将/ foundation-icons文件夹放入我的/ css文件夹中.它是否正确？我试图按照文档"如何使用它们"部分,我无法弄清楚如何开始使用类.

我在我的.html中这样做来调用这些类.

<a class=".fi-social-facebook">Facebook</a>  

所以我假设我必须没有正确配置/设置我的文件字体.

更新:这是我的目录看起来...我正在引用它
,这就是我如何调用该类.

<i class="ft-social-facebook"></i><a href="#">Facebook</a>
<i class="ft-star"></i>

如何配置Sublime Text 3设置,以便特定文件类型具有自己的选项卡大小？我想要ruby到2个tab大小,python = 4,C++ = 4等等.我怎么做这个,而不是每次都手动这样做？

安装调试器时似乎有一个递归效果,gem install debugger -v '1.6.8'它表示安装成功,但是当我这样做时,消息再次出现bundle install或者bundle update

React Native入门.我确实安装了Android SDK,Java SDK和Android依赖项.在终端上运行演示应用程序时收到以下错误.

我确实运行了Galaxy Emulator:

~ emulator @galaxy
HAXM is working and emulator runs in fast virt mode

现在我运行它:

我克隆了一个rails repo,我现在正试图捆绑安装

背景:

• OSX El Capitan
• ruby 2.2.3p173(2015-08-18修订版51636)[x86_64-darwin15]

rails -v无法在Gemfile中列出的或本机上可用的任何gem源中找到gem'pg(> = 0)ruby'.运行bundle install以安装缺少的宝石.

我试图使用JavaScript Date()获取当前日期的月份名称; 类.我注意到除非我用月份名创建一个字符串数组,否则没有办法做到这一点.

var month = new Date();
month.getMonth();
> 10

我希望得到"十一月"而不是整数.是否有一个函数被调用来获取Date()类的字符串名称,或者我是否必须创建一个数组,如:

var monthNames = ["January", "February", "March", "April", "May", "June",
  "July", "August", "September", "October", "November", "December"
];

var d = new Date();
document.write("The current month is " + monthNames[d.getMonth()]);

我知道有库和上面的方法来做到这一点,但我很想知道是否有一个内置函数来执行此操作,我正在忽略.

我已经安装了语义UI rails gem

gem 'semantic-ui-rails'

我现在正尝试使用Symantec UI文档中的以下示例代码创建一个简单的导航栏:

<div class="ui secondary pointing menu">
  <a class="active item">
    Home
  </a>
  <a class="item">
    Messages
  </a>
  <a class="item">
    Friends
  </a>
  <div class="right menu">
    <a class="ui item">
      Logout
    </a>
  </div>
</div>
<div class="ui segment">
  <p></p>
</div>

出现纯文本但没有语义UI格式和样式.我是否需要配置一些内容才能启动和运行语义UI？
