How can I use “watch” GDB?

阅读更多关于 How can I use “watch” GDB?

问题 I tried to watch the change of the "int a" by the command "watch a". However, the program does not stop, when it changes to 12. Why? /* FILE: test.c */ #include <stdio.h> #include <stdlib.h> int main(int argc, char** argv){ printf("Hello world\n"); int a = 12; a = 10; return 0; } 回答1: It may help to specify your platform, version of GDB, and exact sequence of GDB commands you used. Here is what I see (GDB appears to work just fine): $ gcc -g test.c $ gdb a.out GNU gdb (GDB) 6.8.50.20090430

VueJS - Skip watcher's first change

阅读更多关于 VueJS - Skip watcher's first change

问题 I'm creating a component in VueJS for an app I'm making, it has some watchers to apply logic to other parts of the component when my var changes. Once the component is initialized, it still needs to be set by some data from the server coming after a few events done by the user via Axios. This data gets to the component from an event emmited by the main app. Now the thing is that this var usually changes (not always), but I don't want that logic to be applied this first time, so I decided to

What does the {???} mean in the VC++ Watch window?

阅读更多关于 What does the {???} mean in the VC++ Watch window?

问题 I am debugging a C project with Visual Studio 2013. What does the {???} mean in the below Watch window? I guess there must be something wrong and I searched a bit. But no luck. 回答1: Igor’s suggestion is correct, this is the sample for this issue. If I disable the line code “currnode->nextnode = NULL;”, it will show the same result as yours. But if I enable it, it would show the NULL value like this screen shot, so it would be related to null value of the pointer. 来源： https://stackoverflow.com

grunt之watch续

　　上一回没有说完，我就是这样，做之前心中波澜壮阔，锦绣山河，等画完小草开始烦躁，完成鲜花出现动摇，然后心神涣散，最后虎头蛇尾。　　现在弥补下之前遗漏的问题。　　watch(V0.6.1)的tasks和options( github地址 ) watch和之前介绍的plugin有几点不同，首先files的值不是原来对象数组的形式，而是监听的文件的路径的字符串数组。其次，其他plugin的task结构为target+options，watch多一个属性类型，叫tasks，是监听的文件变动后需要执行的任务队列。目录结构还是参照之前，源文件夹是src，目标文件夹是dest，先做一个简单的实现。 'use strict'; module.exports = function(grunt) { require('load-grunt-tasks')(grunt); require('time-grunt')(grunt); var path = { src: 'src', dest: 'dest' } grunt.initConfig({ path: path, copy: { test: { files: [ { expand: true, cwd: '<%=path.src%>/', src: '{,*/}*', dest: '<%=path.dest%>/' } ] } },
