# 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 ``` go get https://github.com/phodal/coca ``` help: ``` Usage: coca [command] Available Commands: analysis analysis package api scan api bs Bad Code Smell call call graph api concept concept api ga git analysis help Help about any command refactor auto refactor code cloc cloc [FILE or DIRECTORY] ``` ### Analysis ``` coca analysis -p [PATH] ``` ### Find Bad Smells ``` coca bs -p examples/api -s type ``` Examples Result: ``` { "dataClass": [ { "File": "examples/api/BookController.java", "BS": "dataClass" } ... ], "lazyElement": [ { "File": "examples/api/model/BookRepresentaion.java", "BS": "lazyElement" } ... ] } ``` ### Code Line Count ``` coca cloc ``` Results: ```
