copypasteck

一个基本的用于检查复制粘贴重复的 rustc lint 插件。这将警告关于有重复条件或内容的 if 和 match 分支。

示例

# Cargo.toml
[package]
name = "example"
version = "0.1.0"
authors = ["You <[email protected]>"]

[dependencies.copypasteck]
git = "https://github.com/huonw/copypasteck"

// 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");
    }
}
