jscpd MCP工具

Installation

$ npm install -g jscpd

Installation

$ npm install -g jscpd-server

Usage

$ npx jscpd /path/to/source

$ jscpd /path/to/code

$ jscpd --pattern "src/**/*.js"

Usage

Start the server:

$ jscpd-server

Check code for duplication:

$ curl -X POST http://localhost:3000/api/check \
  -H "Content-Type: application/json" \
  -d '{
    "code": "console.log(\"hello\");\nconsole.log(\"world\");",
    "format": "javascript"
  }'

23 clones · 4.2% duplication ```

Benchmarked on the fixtures/ directory (91 clones, 132 files):

~79% fewer tokens than the default console reporter.

Programming API

For integration copy/paste detection to your application you can use programming API:

jscpd Promise API

import {IClone} from '@jscpd/core';
import {jscpd} from 'jscpd';

const clones: Promise<IClone[]> = jscpd(process.argv);

jscpd async/await API

import {IClone} from '@jscpd/core';
import {jscpd} from 'jscpd';
(async () => {
  const clones: IClone[] = await jscpd(['', '', __dirname + '/../fixtures', '-m', 'weak', '--silent']);
  console.log(clones);
})();

detectClones API

import {detectClones} from "jscpd";

(async () => {
  const clones = await detectClones({
    path: [
      __dirname + '/../fixtures'
    ],
    silent: true
  });
  console.log(clones);
})()

detectClones with persist store

import {detectClones} from "jscpd";
import {IMapFrame, MemoryStore} from "@jscpd/core";

(async () => {
  const store = new MemoryStore<IMapFrame>();

  await detectClones({
    path: [
      __dirname + '/../fixtures'
    ],
  }, store);

  await detectClones({
    path: [
      __dirname + '/../fixtures'
    ],
    silent: true
  }, store);
})()

In case of deep customisation of detection process you can build your own tool with @jscpd/core, @jscpd/finder and @jscpd/tokenizer.
