# Coca

[![Build Status](https://travis-ci.org/phodal/coca.svg?branch=master)](https://travis-ci.org/phodal/coca)

> Coca 是一个用于遗留系统重构的瑞士军刀。它可以分析代码中的 badsmell，行数统计，分析调用与依赖，进行 Git 分析，以及自动化重构等。

## Usage

install 

```bash
go get -u github.com/phodal/coca
```

help:

```bash
Usage:
  coca [command]


Available Commands:
  analysis    analysis package
  api         scan api
  bs          bad smell analysis
  call        call graph api
  cloc        cloc [FILE or DIRECTORY]
  concept     concept api
  count       count code
  evaluate    evaluate refactor effort
  git         git analysis
  help        Help about any command
  rcall       reverse call
  refactor    auto refactor code

```

### Analysis

```
coca analysis -p [PATH]
```

### Find Bad Smells

```bash
coca bs -p examples/api -s type
```

Examples Result:

```json
{
   "dataClass": [
      {
         "File": "examples/api/BookController.java",
         "BS": "dataClass"
      }
      ...
   ],
   "lazyElement": [
      {
         "File": "examples/api/model/BookRepresentaion.java",
         "BS": "lazyElement"
      }
      ...
   ]
}
```

### Code Line Count

```
coca cloc
```
