软件包摘要
Copy/paste detector for programming source code
历史
项目历史与用法
jscpd is a copy/paste detector for source code. It scans files for duplicated token sequences, reports clones in multiple formats, and is used as a code-quality gate in local development and CI.
项目历史
The GitHub repository was created in May 2013, and the npm package history begins in June 2013. The name originally stood for JavaScript Copy/Paste Detector, but the project expanded well beyond JavaScript into a broad multi-language duplicate-code scanner.
The README describes the detection engine as Rabin-Karp based. By 2026 the project documentation described support for more than 220 formats, multiple reporters, GitHub Action integration, an MCP server, AI-oriented reporter output, and a Rust-powered v5 engine.
采用历史
jscpd gained adoption as a lightweight alternative to heavier static-analysis suites for teams that wanted to fail builds or generate reports when duplication crossed a threshold. The npm package had a long 0.x to 4.x TypeScript/Node.js history before the 5.x Rust-native release line appeared in June 2026.
Homebrew packages jscpd as a CLI, npm distributes it for JavaScript toolchains, and the project site promotes curl, npm, cargo, brew, and nix installation paths. That multi-channel distribution matches its role as a language-agnostic source-code utility.
使用方式
Developers run jscpd against a repository or source directory, tune thresholds and ignore patterns through configuration such as .jscpd.json, and consume terminal, JSON, HTML, badge, CI, or AI-oriented reports.
为什么软件包爱好者会关心
jscpd is notable because duplicate-code detection sits between linting, static analysis, and build policy. The 2026 Rust rewrite also makes it a packaging case study: a Node-era CLI kept its ecosystem-facing package names while shifting core performance-sensitive work into a native binary.
