godag

godag can help you analyse the pkg internal dependency

1. How to Use

1. Install

go get -u github.com/legendtkl/godag

2. Run

godag --pkg_name=github.com/astaxie/beego --pkg_path=/Users/kltao/code/go/src/github.com/astaxie/beego --depth=1 --dot_file_path=a.dot

Flags

• pkg_name: (REQUIRED) the package name you want to analyze dependency
• pkg_path: (REQUIRED) the package path in your computer
• depth: (Optional) the code depth to analyze. For example, if depth is 1, we will only analyze the pkg dag: beego/cache, beego/context; if depth is 2, we will analyze the pkgs dag: beego/cache/redis, beego/cache/ssdb etc. The default value is 1.
• dot_file_path: (Optional) the dot file path. The default value is godag.dot in current dir.

3. Visualization

You can use graphviz to visualize dot file.

dot -Tpng godag.dot > godag.png
dot -Tsvg godag.dot > godag.svg

With beego in depth=1, we got the png as follow.

Install graphviz

Mac

brew install graphviz

Linux

yum or apt-get or source code

2. Features

• Simple. We depend no third party package.
• Depth Support.
• Something else maybe.

3. Weakness

• Support only third path package analyze. That means, if you want to analyze your local project, you might need to modify the code or contact me.
