What to do if I cannot find my emacs init file?

阅读更多关于 What to do if I cannot find my emacs init file?

I am trying to add haskell-mode to emacs by following these instructions: http://doc.gnu-darwin.org/haskell-mode/installation-guide.html This involves that I add some code to my ~/.emacs init file. However, my issue is that I cannot locate my emacs init file. I tried using find commands to locate it, as so: find . -name "*emacs*" find . -name "~/.emacs" However none of these appear to be very successful, as I get either too many results, or no results. So, given my situation, since I cannot locate my ~/.emacs init file, does this mean it does not exist? In that case, would it be smart to

Objective-C: init vs initialize

阅读更多关于 Objective-C: init vs initialize

问题 In Objective-C, what is the difference between the init method (i.e. the designated initializer for a class) and the initialize method? What initialization code should be put in each? 回答1: -init is an instance method, used to initialize a particular object. +initialize is a class method, run before any instances of the class are created and before other class methods are run. +initialize isn't something you use most of the time, but it's handy for setting up any static variables that the

Guice call init method after instantinating an object

阅读更多关于 Guice call init method after instantinating an object

Is it possible to tell Guice to call some method (i.e. init()) after instantinating an object of given type? I look for functionality similar to @PostConstruct annotation in EJB 3. gpampara Actually, it is possible. You need to define a TypeListener to get the functionality going. Something along the lines of the following in your module definition: bindListener(Matchers.subclassesOf(MyInitClass.class), new TypeListener() { @Override public <I> void hear(final TypeLiteral<I> typeLiteral, TypeEncounter<I> typeEncounter) { typeEncounter.register(new InjectionListener<I>() { @Override public void

How to set which control gets the focus on application start

阅读更多关于 How to set which control gets the focus on application start

问题 For a C# Windows Forms application, how do I set the default focus to a given control when my application starts? 回答1: The one with the minimum tab index automatically gets the focus (assuming the TabStop property is set to true). Just set the tab indices appropriately. By the way, Visual Studio provides a way to easily set tab indices by just clicking on the controls in the order you want. You can activate this feature by choosing "Tab Order" option in the "View" menu when you are in the

中国空气质量在线监测分析平台数据爬取分析页面分析：确定url、请求方式、请求参数、响应数据　　 1.访问网站首页： https://www.aqistudy.cn/html/city_detail.html ，通过抓包工具分析首页请求并没有获取到页面内的数据信息　　 2.因此可以确定页面内的数据是动态加载的，通过抓包工具捕获加密的响应对象，　　 3.加密响应对象是通过post请求携带加密的参数发起（2次）。　　 4.综上分析可以确定，动态请求时在搜索按钮触发时发起的，因此通过火狐firefox浏览器分析页面搜索按钮的绑定事件以及定位到具体的代码在哪一行。　　 5.通过标签绑定事件可以确定是触发了getData()函数，因此对应转包工具捕获到的两次请求，进入js代码，找到函数的执行过程。　　 6。在当前js中搜索找到getAQIData();和getWeatherData();函数，也没发现ajax发起的post请求，但都调用了getServerData函数，只是唯一一个参数不同method = 'GETDETAIL';method = 'GETCITYWEATHER';，因此继续分析getServerData函数。　　 7.在当前js中为找到getServerData 函数定义，切换到google浏览器对请求响应进行全局搜索，获取函数定义--- js反混淆。　　

How to return a value from init in Python?

阅读更多关于 How to return a value from __init__ in Python?

I have a class with an __init__ function. How can I return an integer value from this function when an object is created? I wrote a program, where __init__ does command line parsing and I need to have some value set. Is it OK set it in global variable and use it in other member functions? If so how to do that? So far, I declared a variable outside class. and setting it one function doesn't reflect in other function ?? Can Berk Güder __init__ is required to return None. You cannot (or at least shouldn't) return something else. Try making whatever you want to return an instance variable (or

Inheritance and init method in Python

阅读更多关于 Inheritance and init method in Python

问题 I'm begginer of python. I can't understand inheritance and __init__() . class Num: def __init__(self,num): self.n1 = num class Num2(Num): def show(self): print self.n1 mynumber = Num2(8) mynumber.show() RESULT: 8 This is OK. But I replace Num2 with class Num2(Num): def __init__(self,num): self.n2 = num*2 def show(self): print self.n1,self.n2 RESULT: Error. Num2 has no attribute "n1". In this case, how can Num2 access n1 ? 回答1: In the first situation, Num2 is extending the class Num and since

When is the init() function run?

阅读更多关于 When is the init() function run?

问题 I've tried to find a precise explanation of what the init() function does in Go. I read what Effective Go says but I was unsure if I understood fully what it said. The exact sentence I am unsure is the following: And finally means finally: init is called after all the variable declarations in the package have evaluated their initializers, and those are evaluated only after all the imported packages have been initialized. What does all the variable declarations in the package have evaluated

Subclassing dict: should dict.init() be called?

阅读更多关于 Subclassing dict: should dict.__init__() be called?

问题 Here is a twofold question, with a theoretical part, and a practical one: When subclassing dict: class ImageDB(dict): def __init__(self, directory): dict.__init__(self) # Necessary?? ... should dict.__init__(self) be called, just as a "safety" measure (e.g., in case there are some non-trivial implementation details that matter)? is there a risk that the code break with a future version of Python if dict.__init__() is not called? I'm looking for a fundamental reason of doing one thing or the
