ENRE

ENRE (ENtity Relationship Extractor ) is a tool for extraction of code entity dependencies(relationships) from source code. The resolved dependency types include:

Dependency Type	Description
Import	a File imports a Package, Module, etc.
Implement	A Class implements an Interface.
Extend	A Class inherits a Class.
Call	A function/Method calls A Function/method.
Use	A Function/Method uses or reads a Variable.
Set	A Function/Method uses or reads a Varibale.
Parameter	A Funciton/Method has a Class type parameter.
Return	A Function/Method returns a Class type value.

Features

ENRE supports analyzing source code written in Python, Go.

Usage

1)Prepare the executable jar

The released jar of ENRE is named as ENRE-v1.0.jar.

2) Set up Java environment

To execute ENRE-v1.0.jar, you should set up JAVA envionment. Please referer to Set up JAVA environment.

3) cmd usage

Now, everthing is already prepared well. Let's use ENRE to analyze source code. The usage command is:

java -jar <executable> <lang> <dir> <include-dir> <project-name>

• . The executable jar package of ENRE.
• . The language of source code that will be analyzed. It can be python or golang.
• . The path of the source code that will be analyzed.
• . The github url of source code. It only works when analyzing golang projects. Set it "null" when analyzing python projects.
• . A short alias name of the anayzed source code project.

Example I:

Use ENRE to analyze a demo project "fire" written in Python:

#in linux platform 
$java -jar ENRE-v1.0.jar  python  demo-projects/fire   null  fire   

#in windows platform
$java -jar ENRE-v1.0.jar  python  demo-projects\fire   null  fire 

After analysis, ENRE finally outputs the resovled entities and dependencies in JSON, XML, DOT files in new-generated fire-out/ directory.

Example II:

Use ENRE to analyze a demo project "beego" written in Go:

#in linux platform 
$java -jar ENRE-v1.0.jar  golang  demo-projects/beego   github.com/astaxie/beego  beego  

#in windows platform
$java -jar ENRE-v1.0.jar  golang  demo-projects\beego   github.com/astaxie/beego  beego

After analysis, ENRE finally outputs the resovled entities and dependencies in JSON, XML, DOT files in new-generated beego-out/ directory.
