如何快速查询模块的函数?
发布于 5 天前 作者 gousern 501 次浏览 来自 问答

命令列下有什麼方式可以快速查詢模塊內的函數嗎? 目前缺點

  1. 需要安裝後才能查詢
  2. 只能查詢單一模塊 期待: 能否類似 Linux 底下的 man page。

例如:要查詢 utility 需要先安裝,才能查詢 utility 的函數。

> npm install utility

執行後

> node -pe "require('utility')"

便底下列出了 utility 的函數

{
  noop: [Function: noop],
  getParamNames: [Function: getParamNames],
  setImmediate: [Function: setImmediate] {
    [Symbol(util.promisify.custom)]: [Function]
  },

  dig: [Function],
  argumentsToArray: [Function],
  hash: [Function: hash],
  md5: [Function: md5],
  sha1: [Function: sha1],
  sha256: [Function: sha256],

  MIN_SAFE_INTEGER: -9007199254740991,
  MAX_SAFE_INTEGER_STR: '9007199254740991',
  isSafeNumberString: [Function: isSafeNumberString],

  logDate: [Function],
  YYYYMMDDHHmmss: [Function],
  YYYYMMDD: [Function: YYYYMMDD],
  datestruct: [Function],
  timestamp: [Function: timestamp],
  assign: [Function],
  has: [Function: has],
  getOwnEnumerables: [Function: getOwnEnumerables],
  map: [Function: map],
  escape: [Function: escapeHtml],
  unescape: [Function: unescape] {
    chars: {
      '"': '"',
      '"': '"',
      ''': "'",
      ''': "'",
      '&': '&',
      '&': '&',
      '>': '>',
      '>': '>',
      '&lt;': '<',
      '&#60;': '<'
    },
    extras: {
      '&cent;': '¢',
      '&#162;': '¢',
      '&copy;': '©',
      '&#169;': '©',
      '&euro;': '€',
      '&#8364;': '€',
      '&pound;': '£',
      '&#163;': '£',
      '&reg;': '®',
      '&#174;': '®',
      '&yen;': '¥',
      '&#165;': '¥'
    }
  },
  encodeURIComponent: [Function: encodeURIComponent_],
  decodeURIComponent: [Function: decodeURIComponent_]
}

有比較方便的方式嗎?

难道不应该看文档吗
