vue使用diff-match-patch和codemirror实现文本对比,实现合并功能

<template>
  <div>
    <codemirror ref="cmEditor" :value="code"></codemirror>
  </div>
</template>
 
<script>
import { codemirror } from "vue-codemirror-lite";
import "codemirror/lib/codemirror.css";
import "codemirror/mode/javascript/javascript.js";
import DiffMatchPatch from "diff-match-patch";
 
export default {
  components: {
    codemirror
  },
  data() {
    return {
      code: "// Your code here",
      dmp: new DiffMatchPatch()
    };
  },
  methods: {
    mergeChanges(newCode, oldCode) {
      let diff = this.dmp.diff_main(oldCode, newCode);
      this.dmp.diff_cleanupSemantic(diff);
      let patches = this.dmp.patch_make(oldCode, diff);
      let mergedCode = this.dmp.patch_apply(patches, oldCode)[0];
      return mergedCode;
    }
  }
};
</script>
 
<style>
/* Add global styles for CodeMirror if needed */
</style>

这个代码实例展示了如何在Vue组件中使用vue-codemirror-lite来创建一个代码编辑器，并使用diff-match-patch库来合并编辑器中的代码变更。mergeChanges方法接收新旧两段代码，计算它们的差异，并应用这些差异以合并更改，最后返回合并后的代码。在实际应用中，你可以在需要时调用mergeChanges方法来合并用户的编辑。
