Refactoring Modeling:
- Languages Support: Java (full features)
Features List:
```
Available Commands:
analysis analysis code
api scan HTTP api from annotation
arch project package visualization
bs generate bad smell list and suggestions
call show call graph with specific method
cloc count lines of code with complexity estimation
concept build domain concept from source code
count count most refs function

git analysis git commit history for revs count, summary and suggest
help Help about any command
rcall reverse call graph visualization
refactor auto refactor code
suggest find usable Design Patterns from code
tbs generate tests bad smell
todo scan all todo, and list with time
version version
```
## Getting started
Requirements: [graphviz](https://www.graphviz.org/) for dot file to image (such as svg, png)
The easiest way to get coca is to use one of the pre-built release binaries which are available for OSX, Linux, Windows on the [release page](https://github.com/modernizing/coca/releases).
You can also install yourself :
```bash
go install github.com/modernizing/coca@latest
```
## Usage
### Analysis
```
coca analysis
```
### Arch
```
coca arch
```
Android Studio Gradle DSL Module (merge header)
command: `coca arch -x "com.android.tools.idea.gradle.dsl" -H true`
Android Studio Gradle DSL Module Elements Part:
command: `coca arch -x "com.android.tools.idea.gradle.dsl.parser.elements"`
### Find Bad Smells
```bash
coca bs -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
