由 不打扰是莪最后的温柔 提交于 2019-12-13 04:46:27
问题 I am a newbie to this framework struggling to understand scope . I followed the basic steps for creating a todo app given in the yeoman website. Here is my code : Index.Html <!doctype html> <html class="no-js"> <head> <meta charset="utf-8"> <title></title> <meta name="description" content=""> <meta name="viewport" content="width=device-width"> <link rel="stylesheet" href="bower_components/bootstrap/dist/css/bootstrap.css" /> <link rel="stylesheet" href="styles/main.css"> </head> <body ng-app=

xtext custom scoping: parameters of function

由 杀马特。学长 韩版系。学妹 提交于 2019-12-12 17:51:48
问题 I am trying to custom scoping, such that if I have something like function in my language that get parameters, I want that those parameters will be visible only until there is semicolon, and out of this scope, I want it to not be visible. I tried redefine the method getScope() in the file MyDslScopeProvider.xtend In getScope I did something like this: if (EclassName=="TypedParam" && EFeatureName=="type" && contextType == "TypedParam"){ return Scopes.scopeFor(Collections.singleton(context)

IResourceScopeCache for Avoid expensive scope calculation

由 霸气de小男生 提交于 2019-12-12 04:23:49
问题 I have the same problem that described is this link I want to use IResourceScopeCache in my getScope function I implemented, but I don't know how to do it. Didn't found anything that helped me. I have this file: MyDslScopeProvider.xtend that I override getScope() there. How can I use the cache there? override def IScope getScope(EObject context, EReference reference) { if (reference == SpectraPackage.Literals.TEMPORAL_PRIMARY_EXPR__POINTER) { val contextDecl = EcoreUtil2.getContainerOfType

Understanding nonlocal in Python 3

由 蹲街弑〆低调 提交于 2019-12-11 16:47:46
问题 I am trying to understand Python 3 variable scoping and nonlocal . Consider the following function (it is just an example): def build_property(something): def deco(func): def getter(self): return getattr(self, something) def setter(self, value): setattr(self, something, value) return property(getter, setter) return deco This works fine without nonlocal . But if now I want to conditionally create getters and setters depending on something I need nonlocal. def build_property(something): def

VBScipt: Call builtin functions shadowed by global variables

由 别说谁变了你拦得住时间么 提交于 2019-12-11 15:48:51
问题 VBScript on ASP Classic contains an "int" function. (It rounds numbers towards -∞.) Suppose that some excessively "clever" coder has created a global variable named "int". Is there any way to get at the original function? I've tried all manner of workarounds with scoping and dodgy execs, but no dice. I suspect that it is impossible, but I'm hoping that someone will know more about it than I do. EDIT: Thanks for the responses. Since y'all asked, the global variable, called "Int" (though

ruby variable scoping across classes

由 自古美人都是妖i 提交于 2019-12-11 11:20:33
问题 RuNubie here. I've got a class Login that logs into gmail using the net/IMAP library. What is happening is that I create a new instance of that class, such as: a = Login.new("username", "gmail.com", "passw") Then, I'm working on other classes that will do some "stuff" with the mailbox. The problem is that the @imap variable I've defined in Login seems to have disappeared (due to scoping I assume). This is how @imap is declared in Login class: @imap = Net::IMAP.new('imap.gmail.com',993,true

Oracle - How to have an out ref cursor parameter in a stored procedure?

由 耗尽温柔 提交于 2019-12-11 07:38:59
问题 The standard way that our applications pass information from oracle stored procedures to the oracle .net provider is via an out ref cursor parameter. In the past all of our stored procedures used to be in packages and had something like this: CREATE OR REPLACE PACKAGE test_package IS TYPE refcur IS REF CURSOR; PROCEDURE get_info ( o_cursor OUT refcur ); END test_package; / CREATE OR REPLACE PACKAGE BODY test_package IS PROCEDURE get_info ( o_cursor OUT refcur ) AS BEGIN OPEN o_cursor FOR

Force R function call to be self-sufficient

问题 I'm looking for a way to call a function that is not influenced by other objects in .GlobalEnv . Take a look at the two functions below: y = 3 f1 = function(x) x+y f2 = function(x) { library(dplyr) x %>% mutate(area = Sepal.Length *Sepal.Width) %>% head() } In this case: f1(5) should fail, because y is not defined in the function scope f2(iris) should pass, because the function does not reference variables outside its scope Now, I can overwrite the environment of f1 and f2 , either to baseenv
