description	Design terminal output for a CLI tool with chalk colors, Unicode glyphs, multiple verbosity levels (human, verbose, quiet, JSON), and consistent voice rules. Covers color palette selection, status indicator design, reporter function architecture, ceremony/narrative output variants, and cross-terminal compatibility. Use when building a new CLI reporter module, adding warm narrative output to an existing tool, standardizing output across multiple commands, or designing machine-readable JSON alongside human-readable text.

設計 CLI 輸出

為命令行工具設一致多級終端輸出。

用

• 構 CLI 新報告者模組
• 加暖敘事輸出於標事務輸出
• 標準化多命令輸出格式
• 設並行機可讀 JSON+人可讀輸出
• 擇色、符、冗繁級予新終端工具

入

• 必：CLI 名+主受眾（開發者、運維、終用戶）
• 必：需格式化輸出之命令
• 可：是否欲「儀式」或敘事變體
• 可：品牌限（色板、調）

法

一：定色板

以 chalk 建名板對象。

載 chalk 須置無色退於後。 退須代板所用諸調用形，僅過字串不足：

// A factory returns a *function*; a direct style returns a string. Enumerate
// this list against the installed chalk, not from memory — chalk 6 added the
// three underline* variants, and a list that omits them is wrong for those names.
const FACTORIES = new Set(['ansi256', 'bgAnsi256', 'bgHex', 'bgRgb', 'hex',
  'rgb', 'underlineAnsi256', 'underlineHex', 'underlineRgb']);

function makeChalkStub() {
  return new Proxy((text) => text, {
    get(target, prop) {
      if (prop === 'then') return undefined;   // must not be a thenable
      if (prop === 'level') return 0;          // no color support, truthfully
      if ( prop === )  .(target, prop);
       .(prop) ?  () : ();
    },
  });
}

 chalk;
 { chalk = ( ()).; }
 { chalk = (); }
