VistualCall

VistualCall is a gem to help you trace your code and export beautiful vistual call graph.

Introduction

Dependency

1. Graphviz

You need to install Graphviz by yourself.

Go to install graphviz.

Usage

1. Install gem

gem install vistual_call

2. Only the method needs to be wrapped.

require 'vistual_call'

def call_c
end

def call_b
  call_c
end

def call_a
  call_b
end

VistualCall.trace do
  call_a # enter call
end

The method after each node is call order number. This will help your understand the order of the function call.

用 vistual_call 分析 vistual_call 自己

```ruby
require_relative "vistual_call"

def call_a
end

VistualCall.trace(title: "Outer", show_dot: true) do
VistualCall.trace(title: "Inner", show_dot: true) do
call_a # whatever
end
end
```
