# copypasteck

[![Build Status](https://travis-ci.org/huonw/copypasteck.png)](https://travis-ci.org/huonw/copypasteck)

A basic `rustc` lint plugin for checking for copy-paste

duplication. This will warn about `if` and `match` branches with

duplicated conditions or contents.

## Example

```toml

# Cargo.toml

[package]

name = "example"

version = "0.1.0"

authors = ["You "]

[dependencies.copypasteck]

git = "https://github.com/huonw/copypasteck"

```

```rust

// src/main.rs

#![feature(phase)]

#[phase(plugin)] extern crate copypasteck;

fn main() {

    let a = 10i;

    if a > 5 {

        println!("hi");

    } else if a > 5 {

        println!("bye");

    }

}

```

```
