作者:向生活低头...
这篇文章主要给大家介绍了关于vue3中如何使用codemirror6增加代码提示功能的相关资料,Codemirror是一个不错的Web代码编辑库,可以方便简单的集成,需要的朋友可以参考下
1、安装依赖
// 安装codemirror、语言包、主题、自动补全
npm i codemirror npm i @codemirror/lang-javascript npm i @codemirror/autocomplete npm i @codemirror/theme-one-dark
本人安装的版本是
"dependencies": { "@codemirror/autocomplete": "^6.0.0", "@codemirror/lang-javascript": "^6.0.2", "@codemirror/theme-one-dark": "^6.0.0", "codemirror": "^6.0.1", ... },
2、创建编辑器
<template> <el-select placeholder="请选择分组" v-model="group" clearable @change="insertGroup" > <el-option v-for="dict in groupList :key="dict.id" :label="dict.dgName + '(' + dict.dgCode + ')'" :value="dict.dgCode" ></el-option> </el-select> <el-button @click="codeBeauty" style="margin-bottom: 0.5rem">代码格式化</el-button> <div id="coder"></div> <el-button type="primary" @click="submitForm" v-if="!testFlag">确 定</el-button> </template>
<style scoped> #coder{ margin-top: 10px; width: 100%; } </style>
<script setup name="Command"> import { javascript } from "@codemirror/lang-javascript"; import { oneDark } from "@codemirror/theme-one-dark"; import { basicSetup, EditorView } from "codemirror"; import { autocompletion } from "@codemirror/autocomplete"; const { proxy } = getCurrentInstance(); const allKeyList = ref([]); const groupList = ref([]); const group = ref(""); const data = reactive({ form: {}, }); const { form } = toRefs(data); let editor = null; // 获取自定义提示内容 function getCommandList() { groupList.value = [ { id: '1', label: '分组1', value: 'group1' }, { id: '2', label: '分组2', value: 'group2' }, ]; allKeyList.value = [ { label: "@match", type: "keyword", apply: "match", detail: "match" }, { label: "@hello", type: "variable", apply: "hello", detail: "hellodetail" }, { label: "@magic", type: "text", apply: "⠁⭒*.✩.*⭒⠁", detail: "macro" }, ]; } // 代码美化 function codeBeauty() { editor.dispatch({ changes: { from: 0, to: editor.state.doc.length, insert:js_beautify(getCommanContent() || "") }, }); } // 获取当前编辑器中的内容字符串 function getCommanContent() { let str = "" editor.state.doc.children.forEach((el,index) => { str += el.text.join("\n") + "\n" }) return str.slice(0,-1); } // 初始化编辑器 function initCodeContent(){ setTimeout(() => { if(!editor) { editor = new EditorView({ doc: "Press Ctrl-Space in here...\n", extensions: [ basicSetup, javascript(), oneDark, autocompletion({ override: [myCompletions] }), // EditorView.updateListener.of((v) => { // console.log(v.state.doc.toString()) // }), ], parent: document.getElementById("coder"), options: { lineNumbers: true, line: true, //ctrl-space唤起智能提示 extraKeys: { Ctrl: "autocomplete", }, //括号匹配 matchBrackets: true, }, }); } editor.dispatch({ changes: { from: 0, to: editor.state.doc.length, insert: form.value.commandContent || "Press Ctrl-Space in here...\n" }, }); }, 500); } // 自定义的代码不全,options为自定义内容,以@开头进行匹配 function myCompletions(context) { let word = context.matchBefore(/@\w*/); if (!word && !context.explicit) return null; return { from: word.from ? word.from : context.pos, options: allKeyList.value, }; } // 选择分组添加到编辑其中 function insertGroup() { insertCommandContant(group.value); group.value = ""; } // 外部输入内容,添加到编辑器当前光标(或选中内容)所在的位置 function insertCommandContant(insertContent) { editor.dispatch({ changes: { from: editor.state.selection.ranges[0].from, to: editor.state.selection.ranges[0].to, insert: insertContent }, }); } /** 提交按钮 */ function submitForm() { proxy.$modal.loading("正在保存,请稍候..."); form.value.commandContent = getCommanContent(); addForm(form.value).then((response) => { proxy.$modal.msgSuccess("新增成功"); proxy.$modal.closeLoading(); }).catch((err) => {proxy.$modal.closeLoading();}); } getCommandList(); initCodeContent(); </script>
