javascript - 用于 nodejs 自动完成的 Ternjs

Question

我正在尝试使用 nodejs 和 tern 打印 js 文件的自动完成。Ternjs 拥有我见过的最糟糕的文档。

var tern = require("tern")

var ternServer = new tern.Server({})

var requestDetails = {
        "query": {
            "type": "completions",
            "file": "myfile.js",
            "end": {"line":0,"ch":3},
            "types":true,
            "includeKeywords":true,
            "sort":true,
            "guess":true,
            "docs":true,
            "urls":true,
            "origins":true,
            "lineCharPositions":true,
            "caseInsensitive":true
        },
        "files": [
            {
                "type": "full",
                "name": "myfile.js",
                "text": 'req'
            }
        ]
}

ternServer.request(requestDetails, function(error, success){
    console.log(success);
});

如果我使用 con，它提供了 continue 和 const，但它不起作用。但不是在那之后。在 atom 插件中，它提供了 require 模块自动完成功能。我是不是错过了什么。

这也是 .tern-project 文件

{
  "ecmaVersion": 6,
  "libs": [
    "browser",
    "jquery",
    "requirejs",
    "commonjs"
  ],
  "plugins": {
    "complete_strings": {
      "maxLength": 15
    },
    "node": {},
    "lint": {},
    "doc_comment": {
      "fullDocs": true,
      "strong": true
    }
  }
}

以这种方式启动服务器时，不会加载自动完成库。简单地在 .tern_project 文件中定义它们似乎不起作用。

如果您使用 node_modules/tern/bin/tern 启动服务器，您将获得一个端口，然后您可以成功地 POST 请求并通过这种方式获得完成。

curl -H "Content-Type:e": "completions","file": "myfile.js","end": {"line":0,"ch":3},"types":true,"includeKeywords":true,"sort":true,"guess":true,"docs":true,"urls":true,"origins":true,"lineCharPositions":true,"caseInsensitive":true},"files": [{"type": "full","name": "myfile.js","text": "req"}]}' http://localhost:[PORT]

如果这对您不起作用，您可以像这样手动添加 def 文件。

var tern = require("tern");
var fs = require("fs");

var ternServer = new tern.Server({ "async": true, "defs": findDefs()})
var requestDetails = {
    "query": {
        "type": "completions",
        "file": "myfile.js",
        "end": { "line": 0, "ch": 3 },
        "types": true,
        "includeKeywords": true,
        "sort": true,
        "guess": true,
        "docs": true,
        "urls": true,
        "origins": true,
        "lineCharPositions": true,
        "caseInsensitive": true,
    },
    "files": [{
        "type": "full",
        "name": "myfile.js",
        "text": 'req'
    }]
}

ternServer.request(requestDetails, function(error, success) {
    console.log(success);
});

function findDefs() {
  var defs = [];
  defs.push(JSON.parse(fs.readFileSync("node_modules/tern/defs/ecmascript.json", "utf8")));
  defs.push(JSON.parse(fs.readFileSync("node_modules/tern/defs/browser.json", "utf8")));
  defs.push(JSON.parse(fs.readFileSync("node_modules/tern/defs/jquery.json", "utf8")));
  defs.push(JSON.parse(fs.readFileSync("node_modules/tern/defs/underscore.json", "utf8")));
  return defs;
}
