code-tracer

提供一种在 Terminal 环境下对代码位置的执行堆栈进行跟踪，并提供nodejs版本提供核心模型中提供的方法github库上的链接访问，该插件主要用于对源代码研究和代码执行逻辑的学习及跟踪的需要。

如何使用

安装

npm install --save code-tracer

使用

在--debug模式下将启用日志打印功能

var tracer = require('code-tracer');

// 打印当前的信息，类似console.log
tracer.log('I am watching');

// 打印当前位置的代码堆栈信息
tracer.stack('What is stacks?');
